Use of task-shifting to rapidly scale-up HIV treatment services: experiences from Lusaka, Zambia

Training primary healthcare workers on a task-strengthening strategy for integrating hypertension management into HIV care in Nigeria: implementation strategies, knowledge uptake, and lessons learned

BACKGROUND

With improved access to anti-retroviral drugs, persons living with HIV/AIDS (PLWHA) are living longer but with attendant increased risks of non-communicable diseases (NCDs). The increasing burden of NCDs, especially hypertension, could reverse gains attributed to HIV care. Nurses and Community Health Officers (CHO) in Nigeria are cardinal in delivering primary health care. A task-strengthening strategy could enable them to manage hypertension in HIV care settings. This study aimed to assess their knowledge and practice of hypertension management among Healthcare workers (HCWs) and to explore the challenges involved in conducting onsite training during pandemics.

METHODS

Nurses and CHOs in the employment of the Lagos State Primary Health Care Board (LSPHCB), Lagos State, Nigeria, were recruited. They were trained through hybrid (virtual and onsite) modules before study implementation and a series of refresher trainings. A pre-and post-training test survey was administered, followed by qualitative interviews to assess skills and knowledge uptake, the potential barriers and facilitators of task-sharing in hypertension management in HIV clinics, and the lessons learned.

RESULTS

Sixty HCWs participated in the two-day training at baseline. There was a significant improvement in the trainees' knowledge of hypertension management and control. The average score during the pre-test and post-test was 59% and 67.6%, respectively. While about 75% of the participants had a good knowledge of hypertension, its cause, symptoms, and management, 20% had moderate knowledge, and 5% had poor knowledge at baseline. There was also an increase in the mean score between the pre-test and post-test of the refresher training using paired t-tests (P < 0.05). Role-playing and multimedia video use improved the participants' uptake of the training. The primary barrier and facilitator of task sharing strategy in hypertension management reported were poor delineation of duties among HCWs and the existing task shifting at the Primary Healthcare Centres (PHC) level, respectively.

CONCLUSIONS

The task strengthening strategy is relevant in managing hypertension in HIV clinics in Nigeria. The capacity development training for the nurses and CHOs involved in the Integration of Hypertension Management into HIV Care in Nigeria: A Task Strengthening Strategy (TASSH-Nigeria) study yielded the requisite improvement in knowledge uptake, which is a reassurance of the delivery of the project outcomes at the PHCs.

Community Health Workers and Stigma Associated with Mental Illness: An Integrative Literature Review

Community health workers (CHWs) are facilitators between health services and service users, providing essential and effective support to those seeking health care. However, stigmatizing attitudes towards people with mental illness also exist among CHWs and are based on prejudicial and biasedopinions. This integrative review critically assessed evidence regarding CHWs approaches for addressing mental health issues. In total, 19 studies were included in this review. The results revealed that CHWs have limited knowledge about mental illness and also stigmatizing attitudes towards people with mental illness or substance use problems. Despite feeling unprepared, CHWs are favorable resources for mental health care and can contribute to reducing stigma due to the similarities they share with the communities that they serve. Task-sharing between health professionals and CHWs is an important strategy to improve access to health services and reducing stigma towards people with mental illness, provided that receive adequate training to perform the duties.

Doctor Clerk Implementation in Rural Community Hospitals for Effective Task Shifting of Doctors: A Grounded Theory Approach

With the diversification of medical care and work reform, doctor clerks play a major role today and are recruited to mitigate the burden of doctors worldwide. Their recruitment can improve the working conditions of physicians, facilitate task shifting in rural community hospitals, improve patient care, and help address the lack of healthcare resources. This study used a qualitative method to investigate difficulties in the implementation of doctor clerks and ascertain the features of effective implementation by collecting ethnographic data through field notes and semi-structured interviews with workers. We observed and interviewed 4 doctor clerks, 10 physicians, 14 nurses, 2 pharmacists, 1 nutritionist, and 2 therapists for our study. We clarified the doctor clerk process in rural hospitals through four themes: initial challenge, balance between education and expansion, vision for work progression, and drive for quality of care. We further clarified effectiveness, difficulties, and enhancing factors in implementation. Doctor clerk recruitment and bridging of discrepancies among medical professionals can mitigate professional workloads and improve staff motivation, leading to better interprofessional collaboration and patient care.

"Provider discretionary power practices to support implementation of patient-centered HIV care in Lusaka, Zambia"

Introduction

Traditional patient-provider relationships privilege the providers, as they possess the formal authority and clinical knowledge applied to address illness, but providers also have discretion over how they exercise their power to influence patients' services, benefits, and sanctions. In this study, we assessed providers' exercise of discretionary power in implementing patient-centered care (PCC) practices in Lusaka, Zambia.

Methods

HIV clinical encounters between patients on antiretroviral therapy (ART) and providers across 24 public health facilities in Lusaka Province were audio recorded and transcribed verbatim. Using qualitative content analysis, we identified practices of discretionary power (DP) employed in the implementation of PCC and instances of withholding DP. A codebook of DP practices was inductively and iteratively developed. We compared outcomes across provider cadres and within sites over time.

Results

We captured 194 patient-provider interactions at 24 study sites involving 11 Medical Officers, 58 Clinical Officers and 10 Nurses between August 2019 to May 2021. Median interaction length was 7.5 min. In a hierarchy where providers dominate patients and interactions are rapid, some providers invited patients to ask questions and responded at length with information that could increase patient understanding and agency. Others used inclusive language, welcomed patients, conducted introductions, and apologized for delayed services, narrowing the hierarchical distance between patient and provider, and facilitating recognition of the patient as a partner in care. Although less common, providers shared their decision-making powers, allowing patients to choose appointment dates and influence regimens. They also facilitated resource access, including access to services and providers outside of scheduled appointment times. Application of DP was not universal and missed opportunities were identified.

Conclusion

Supporting providers to recognize their power and intentionally share it is both inherent to the practice of PCC (e.g., making a patient a partner), and a way to implement improved patient support. More research is needed to understand the application of DP practices in improving the patient-centeredness of care in non-ART settings.

Retention of knowledge and clinical competence among Ugandan mid-level health providers 1 year after intensive clinical mentorship in TB and HIV management

INTRODUCTION

Clinical mentorship is effective in improving knowledge and competence of health providers and may be a useful task sharing approach for improving antiretroviral therapy. However, the endurance of the effect of clinical mentorship is uncertain.

METHODS

The midlevel health providers who participated in a cluster-randomized trial of one-on-one, on-site, clinical mentorship in tuberculosis and HIV for 8 h a week, every 6 weeks over 9 months were followed to determine if the gains in knowledge and competence that occurred after the intervention were sustained 6- and 12-months post-intervention. In December 2014 and June 2015, their knowledge and clinical competence were respectively assessed using vignettes and a clinical observation tool of patient care. Multilevel mixed effects regression analysis was used to compare the differences in mean scores for knowledge and clinical competence between times 0, 1, 2, and 3 by arm.

RESULTS

At the end of the intervention phase of the trial, the mean gain in knowledge scores and clinical competence scores in the intervention arm was 13.4% (95% confidence interval ([CI]: 7.2, 19.6), and 27.8% (95% CI: 21.1, 34.5) respectively, with no changes seen in the control arm. Following the end of the intervention; knowledge mean scores in the intervention arm did not significantly decrease at 6 months (0.6% [95% CI - 1.4, 2.6]) or 12 months (- 2.8% [95% CI: - 5.9, 0.3]) while scores in the control arm significantly increased at 6 months (6.6% [95% CI: 4.4, 8.9]) and 12 months (7.9% [95% CI: 5.4, 10.5]). Also, no significant decrease in clinical competence mean scores for intervention arm was seen at 6 month (2.8% [95% CI: - 1.8, 7.5] and 12 months (3.7% [95% CI: - 2.4, 9.8]) while in the control arm, a significant increase was seen at 6 months (5.8% [95% CI: 1.2, 10.3] and 12 months (11.5% [95% CI: 7.6, 15.5]).

CONCLUSIONS

Mentees sustained the competence and knowledge gained after the intervention for a period of one year. Although, there was an increase in knowledge in the control group over the follow-up period, MLP in the intervention arm experienced earlier and sustained gains. One-on-one clinical mentorship should be scaled-up as a task-sharing approach to improve clinical care. Trial Registration The study received ethics approvals from 3 institutions-the US Centers for Disease Control and Prevention Institutional Review Board (USA), the Institutional Review Board "JCRC's HIV/AIDS Research Committee" IRB#1-IRB00001515 with Federal Wide Assurance number (FWA00009772) based in Kampala and the Uganda National Council of Science and Technology (Uganda) which approves all scientific protocols to be implemented in Uganda.

Reorienting Primary Health Care Services for Non-Communicable Diseases: A Comparative Preparedness Assessment of Two Healthcare Networks in Malawi and Zambia

Despite positive NCD policies in recent years, majority of Sub-Saharan African (SSA) health systems are inadequately prepared to deliver comprehensive first-line care for NCDs. Primary health care (PHC) settings in countries like Malawi and Zambia could be a doorway to effectively manage NCDs by moving away from delivering only episodic care to providing an integrated approach over time. As part of a collaborative health system strengthening project, we assessed and compared the preparedness and operational capacity of two target networks of public PHC settings in Lilongwe (Malawi) and Lusaka (Zambia) to integrate NCD services within routine service delivery. Data was collected and analyzed using validated health facility survey tools. These baseline assessments conducted between August 2018 and March 2019, also included interviews with 20 on-site health personnel and focal persons, who described existing barriers in delivering NCD services. In both countries, policy directives to decentralize disease-specific NCD services to the primary care level were initiated to meet increased demand but lacked operational guidance. In general, the assessed PHC sites were inadequately prepared to integrate NCDs into various service delivery domains, thus requiring further support. In spite of existing multi-faceted limitations, there was motivation among healthcare staff to provide NCD services.

Client and provider preferences for HIV care: Implications for implementing differentiated service delivery in Thailand

INTRODUCTION

Differentiated service delivery (DSD) for antiretroviral therapy (ART) maintenance embodies the client-centred approach to tailor services to support people living with HIV in adhering to treatment and achieving viral suppression. We aimed to assess the preferences for HIV care and attitudes towards DSD for ART maintenance among ART clients and providers at healthcare facilities in Thailand.

METHODS

A cross-sectional study using self-administered questionnaires was conducted in September-November 2018 at five healthcare facilities in four high HIV burden provinces in Thailand. Eligible participants who were ART clients aged ≥18 years and ART providers were recruited by consecutive sampling. Descriptive statistics were used to summarize demographic characteristics, preferences for HIV services and expectations and concerns towards DSD for ART maintenance.

RESULTS

Five hundred clients and 52 providers completed the questionnaires. Their median ages (interquartile range; IQR) were 38.6 (29.8 to 45.5) and 37.3 (27.3 to 45.1); 48.5% and 78.9% were females, 16.8% and 1.9% were men who have sex with men, and 2.4% and 7.7% were transgender women, respectively. Most clients and providers agreed that ART maintenance tasks, including ART refill, viral load testing, HIV/sexually transmitted infection monitoring, and psychosocial support should be provided at ART clinics (85.2% to 90.8% vs. 76.9% to 84.6%), by physicians (77.0% to 94.6% vs. 71.2% to 100.0%), every three months (26.7% to 40.8% vs. 17.3% to 55.8%) or six months (33.0% to 56.7% vs. 28.9% to 80.8%). Clients agreed that DSD would encourage their autonomy (84.9%) and empower responsibility for their health (87.7%). Some clients and providers disagreed that DSD would lead to poor ART retention (54.0% vs. 40.4%), increased loss to follow-up (52.5% vs. 42.3%), and delayed detection of treatment failure (48.3% vs. 44.2%), whereas 31.4% to 50.0% of providers were unsure about these expectations and concerns.

CONCLUSIONS

Physician-led, facility-based clinical consultation visit spacing in combination with multi-month ART refill was identified as one promising DSD model in Thailand. However, low preference for decentralization and task shifting may prove challenging to implement other models, especially since many providers were unsure about DSD benefits. This calls for local implementation studies to prove feasibility and governmental and social support to legitimize and normalize DSD in order to gain acceptance among clients and providers.

Achieving universal access to obstetric ultrasound in resource constrained settings: A narrative review

OBJECTIVES

The potential benefits and challenges of achieving universal access to obstetric ultrasound services in resource constrained settings were reviewed, with a view to making some recommendations to address the huge burden of avoidable maternal and child morbidity and mortality.

KEY FINDINGS

In most resource-poor settings of the world, antenatal ultrasound is available only to a privileged few in urban centres, while the majority of the population living in rural areas have little or no access to diagnostic imaging services. There is also the extreme shortage of sonographers and doctors with specialist training in sonography. A comprehensive regulation must be put in place to achieve maximum benefits and to ensure quality assurance; appropriate use and application of ethics and training must be comprehensive.

CONCLUSION

Ultrasound service provision, in resource-scarce settings, has the potential to improve access and quality of health care services in areas like the point of care ultrasound service provision and in the fields of obstetrics and gynaecology. A comprehensive regulation must be put in place to achieve maximum benefits and to ensure quality assurance.

IMPLICATIONS FOR PRACTICE

Making ultrasound technology available and affordable in resource scare settings has the potential to improve access to diagnostic imaging services and reduce avoidable maternal and child death in resource constrained settings.

"They have been neglected for a long time": a qualitative study on the role and recognition of rural health motivators in the Shiselweni region, Eswatini

BACKGROUND

Community health workers (CHWs) are increasingly engaged to address human resource shortages and fill primary healthcare gaps. In Eswatini, a cadre of CHWs called Rural Health Motivators (RHM) was introduced in 1976 to respond to key public health challenges. However, the emergence of health needs, particularly HIV/TB, has been met with inadequate programme amendments, and the role of RHMs has become marginalised following the addition of other CHWs supported by non-governmental organisations. This study was implemented to understand the role of RHMs in decentralised HIV/TB activities. In this paper, we explore the findings in relation to the recognition of RHMs and the programme.

METHODS

This exploratory qualitative study utilised individual in-depth interviews, group and focus group discussions, participatory methods (utilising a game format) and observations. Participants were purposively selected and comprised RHM programme implementers, community stakeholders and local and non-governmental personnel. Data collection took place between August and September 2019. Interviews were conducted in English or siSwati and transcribed. SiSwati interviews were translated directly into English. All interviews were audio-recorded, manually coded and thematically analysed. Data was validated through methodical triangulation.

RESULTS

Suboptimal organisational structure and support, primarily insufficient training and supervision for activities were factors identified through interviews and observation activities. Significant confusion of the RHM role was observed, with community expectations beyond formally endorsed tasks. Community participants expressed dissatisfaction with receiving health information only, preferring physical assistance in the form of goods. Additionally, gender emerged as a significant influencing factor on the acceptability of health messages and the engagement of RHMs with community members. Expectations and structurally limiting factors shape the extent to which RHMs are recognised as integral to the health system, at all social and organisational levels.

CONCLUSIONS

Findings highlight the lack of recognition of RHMs and the programme at both community and national levels. This, along with historical neglect, has hindered the capacity of RHMs to successfully contribute to positive health outcomes for rural communities. Renewed attention and support mechanisms for this cadre are needed. Clarification of the RHM role in line with current health challenges and clearer role parameters is essential.

PREDICTORS OF WILLINGNESS TO TASK SHIFT AMONG FAMILY PLANNING PROVIDERS IN A SOUTH-WESTERN NIGERIAN STATE

BACKGROUND

Task shifting, the balanced reallocation of tasks usually from a higher cadre to a lower cadre among the health workforce team, has been proposed as a possible solution to the serious shortage of human resource in the health sector is being experienced in many developing countries. This study aimed to assess the views and experiences of nurses on task shifting in family planning services in Ibadan, Southwest Nigeria.

METHODOS

A descriptive cross-sectional study of 400 nurses with at least a year experience in providing family planning services at purposively selected tetiary, secondary and primary facilities in Ibadan was carried out using an intervieweradministered questionnaire. Chi-square test was used to determine association between categorical variables at 5% level of significance.

RESULTS

Mean age of the respondents was 41.1±8.7 years and 62% of the respondents were registered nurses/registered midwives. Although majority (91.5%) of the respondents were aware of the concept of task shifting, only 52.2% were willing to task shift family planning services to lower cadre staff and only 38.5% have actually task shifted family planning services to lower cadre staff. Age, educational status and awareness about task shifting were predictors of willingness to task shift family planning services.

CONCLUSION

Older registered nurses or registered midwives who were aware of the concept of task shifting were more willing to task shift family planning services. Also, a combination of both awareness and willingness to task shift among married women enhances the practice of task shifting of family planning services.

Effects of real-time electronic data entry on HIV programme data quality in Lusaka, Zambia

SETTING

Human immunodeficiency virus (HIV) clinics in five hospitals and five health centres in Lusaka, Zambia, which transitioned from daily entry of paper-based data records to an electronic medical record (EMR) system by dedicated data staff (Electronic-Last) to direct real-time data entry into the EMR by frontline health workers (Electronic-First).

OBJECTIVE

To compare completeness and accuracy of key HIV-related variables before and after transition of data entry from Electronic-Last to Electronic-First.

DESIGN

Comparative cross-sectional study using existing secondary data.

RESULTS

Registration data (e.g., date of birth) was 100% complete and pharmacy data (e.g., antiretroviral therapy regimen) was <90% complete under both approaches. Completeness of anthropometric and vital sign data was <75% across all facilities under Electronic-Last, and this worsened after Electronic-First. Completeness of TB screening and World Health Organization clinical staging data was also <75%, but improved with Electronic-First. Data entry errors for registration and clinical consultations decreased under Electronic-First, but errors increased for all anthropometric and vital sign variables. Patterns were similar in hospitals and health centres.

CONCLUSION

With the notable exception of clinical consultation data, data completeness and accuracy did not improve after transitioning from Electronic-Last to Electronic-First. For anthropometric and vital sign variables, completeness and accuracy decreased. Quality improvement interventions are needed to improve Electronic-First implementation.

Implementation strategies for infection prevention and control promotion for nurses in Sub-Saharan Africa: a systematic review

Background

Despite impressive reductions in infectious disease burden within Sub-Saharan Africa (SSA), half of the top ten causes of poor health or death in SSA are communicable illnesses. With emerging and re-emerging infections affecting the region, the possibility of healthcare-acquired infections (HAIs) being transmitted to patients and healthcare workers, especially nurses, is a critical concern. Despite infection prevention and control (IPC) evidence-based practices (EBP) to minimize the transmission of HAIs, many healthcare systems in SSA are challenged to implement them. The purpose of this review is to synthesize and critique what is known about implementation strategies to promote IPC for nurses in SSA.

Methods

The databases, PubMed, Ovid/Medline, Embase, Cochrane, and CINHAL, were searched for articles with the following criteria: English language, peer-reviewed, published between 1998 and 2018, implemented in SSA, targeted nurses, and promoted IPC EBPs. Further, 6241 search results were produced and screened for eligibility to identify implementation strategies used to promote IPC for nurses in SSA. A total of 61 articles met the inclusion criteria for the final review. The articles were evaluated using the Joanna Briggs Institute’s (JBI) quality appraisal tools. Results were reported using PRISMA guidelines.

Results

Most studies were conducted in South Africa (n = 18, 30%), within the last 18 years (n = 41, 67%), and utilized a quasi-experimental design (n = 22, 36%). Few studies (n = 14, 23%) had sample populations comprising nurses only. The majority of studies focused on administrative precautions (n = 36, 59%). The most frequent implementation strategies reported were education (n = 59, 97%), quality management (n = 39, 64%), planning (n = 33, 54%), and restructure (n = 32, 53%). Penetration and feasibility were the most common outcomes measured for both EBPs and implementation strategies used to implement the EBPs. The most common MAStARI and MMAT scores were 5 (n = 19, 31%) and 50% (n = 3, 4.9%) respectively.

Conclusions

As infectious diseases, especially emerging and re-emerging infectious diseases, continue to challenge healthcare systems in SSA, nurses, the keystones to IPC practice, need to have a better understanding of which, in what combination, and in what context implementation strategies should be best utilized to ensure their safety and that of their patients. Based on the results of this review, it is clear that implementation of IPC EBPs in SSA requires additional research from an implementation science-specific perspective to promote IPC protocols for nurses in SSA.

Accurate dried blood spots collection in the community using non-medically trained personnel could support scaling up routine viral load testing in resource limited settings

Regular plasma HIV-RNA testing for persons living with HIV on antiretroviral therapy (ART) is now the global standard, but as many as 60% of persons in Africa today on ART do not have access to standard laboratory HIV-RNA assays. As a result, patients in Zambia often receive treatment without any means of determining true virologic failure, which poses a risk of premature switch of ART regimens and widespread HIV drug resistance. Dry blood spots (DBS) on the other hand require unskilled personnel and less complex storage supply chain so are ideal to capture viral-load results from HIV patients outside clinic settings. We assess collection of DBS in the community using non-medically trained personnel (NMP) and documented challenges. We trained 23 NMP to collect DBS from lost to follow-up (LTFU) patients in 4 rural and urban Zambian districts. We developed a phlebotomy box to transport DBS without contamination at ambient temperature and concomitant training and standard operating procedures. We evaluated this through field observations, bi-weekly meetings, reports, and staff meetings. The laboratory assessed DBS quality for testing validity. We attempted to collect DBS from 357 participants in the community. Though individual reasons for refusal from the remaining 37% were not collected, NMPs reported privacy concerns, awkward box-size which drew attention in the community and fears of undisclosed uses of samples related to witchcraft and circulating narratives about past research. Successful DBS collection was not associated with patient gender, age, time on ART, enrolment CD4, facility. DBS viral-load collection by NMP is feasible in Zambia. Our training approach and assessments of NMP not part of the health system can be extended to patients by giving them more responsibility to manage their own differentiated care groups. Concerted efforts that compare collection of DBS by NMP to those collected by skilled-medical personnel are needed.

Perceptions on the feasibility of decentralizing phlebotomy services in community anti-retroviral therapy group model in Lusaka, Zambia

BACKGROUND

The focus of the community anti-retroviral therapy Group model is on drug refill, adherence and support groups. However, laboratory services are completely neglected in this model, and stable patient still have to go to the clinic for blood draws after drugs refills from the community. Due to the introduction of new ART drugs, the guidelines now recommend the use of viral loads to guide decision in switching all patients from NNRTI to dolutegravir based first line ART regimens. But the national viral load testing coverage stands at 37% and and falls short of meeting the global UNAIDS and phlebotomy delivery system is congested. The purpose of this study was to identify the perceptions in decentralizing phlebotomy services into the community anti-retroviral therapy Group model.

METHOD

A qualitative case study design was used. Data were collected through ten Focused group discussions among community anti-retroviral therapy Group members, community and health care workers at anti-retroviral therapy clinics and in-depth interviews with five key informants. Data were managed with the help of Nvivo version 10 and analyzed using thematic method.

RESULTS

Positive perceptions were identified as those which contributed to decongesting phlebotomy rooms, reduced missing phlebotomy appointments, work Load, and lost results. Improved quality of phlebotomy service delivery and testing coverage, innovative access to laboratory services and encouraged patient's accountability. The negative perceptions were compromised sample integrity, inability to perform prevention control and patients less contact with clinicians.

CONCLUSION

The study has demonstrated that decentralizing phlebotomy services within the CAG model has greater potential to improve the quality of services delivery for patients. In addition, it has perceived threats on the quality of specimen collected, patient's safety, and health care.

Factors influencing the confidence and knowledge of nurses prescribing antiretroviral treatment in a rural and urban district in the Western Cape province

Background

Since the introduction of nurse-initiated and managed antiretroviral treatment (NIMART) in South Africa in 2010, initiation of antiretroviral therapy (ART) in primary care has become the responsibility of nurses. The continued success of this approach is dependent on factors such as adequate training and effective support systems.

Objectives

This study aimed to investigate factors influencing the knowledge and confidence of professional nurses in managing patients living with human immunodeficiency virus (HIV) in primary healthcare settings in a rural and urban district in the Western Cape.

Methods

A cross-sectional survey was conducted amongst 77 NIMART-trained nurses from 29 healthcare facilities to measure demographic details, influencing factors, HIV management confidence and HIV management knowledge.

Results

The majority of participants had adequate HIV management knowledge and reported being very confident or expert in the HIV management skills or competencies. Participants trained recently on local guidelines (Practical Approach to Care Kit) (3 years ago or less) had significantly higher knowledge scores. Regular feedback about clinic and personal performance was associated with higher HIV management knowledge. Participants who received NIMART mentoring over a period of 2 weeks had a higher mean confidence score compared to other periods of mentoring. A higher caseload of patients living with HIV was also associated with higher knowledge and confidence.

Conclusion

Training, mentorship and clinical practice experience are associated with knowledge and confidence. Recommendations include the strengthening of current training and mentoring and ensuring that NIMART-trained nurses are provided with regular updates and sufficient opportunities for clinical practice.

[Human Resources for health policy mapping in Francophone African countries.]

OBJECTIVE

To identify all training, recruitment, deployment and retention programmes for healthcare human resources in five Francophone African countries in order to analyse progress in the authorities' efforts to resolve the problems of human resources for health.

METHODS

Analysis of policy processes was based on the University of Wisconsin logical framework approach to identify and describe programmes detailing missions and objectives, and outcome indicators. Data were derived from document analysis and interviews with key resource persons (N = 69).

RESULTS

Four main processes were identified: (1) training policies; (2) recruitment interventions; (3) strategies to improve governance by the creation of professional boards; (4) interventions on financial and non-financial incentive mechanisms. Two main groups of countries can be distinguished. One group presents a coherent succession of strategy integration (Burkina Faso, Mali) focusing on training policies to gradually move towards recruitment policies, deployment and incentive mechanisms. The other group presents a rupture of this political process with a return to training policies (Chad, Côte d'Ivoire) and recruitment and deployment policies (Côte d'Ivoire).

CONCLUSION

This study highlights the absence of structural reforms to improve health care performance to achieve Universal Health Coverage. A lack of policy impact evaluation and evidence-based data was also observed.

Barriers and facilitators to the implementation of doctor-nurse substitution strategies in primary care: a qualitative evidence synthesis

BACKGROUND

Having nurses take on tasks that are typically conducted by doctors (doctor-nurse substitution, a form of 'task-shifting') may help to address doctor shortages and reduce doctors' workload and human resource costs. A Cochrane Review of effectiveness studies suggested that nurse-led care probably leads to similar healthcare outcomes as care delivered by doctors. This finding highlights the need to explore the factors that affect the implementation of strategies to substitute doctors with nurses in primary care. In our qualitative evidence synthesis (QES), we focused on studies of nurses taking on tasks that are typically conducted by doctors working in primary care, including substituting doctors with nurses or expanding nurses' roles.

OBJECTIVES

(1) To identify factors influencing implementation of interventions to substitute doctors with nurses in primary care. (2) To explore how our synthesis findings related to, and helped to explain, the findings of the Cochrane intervention review of the effectiveness of substituting doctors with nurses. (3) To identify hypotheses for subgroup analyses for future updates of the Cochrane intervention review.

SEARCH METHODS

We searched CINAHL and PubMed, contacted experts in the field, scanned the reference lists of relevant studies and conducted forward citation searches for key articles in the Social Science Citation Index and Science Citation Index databases, and 'related article' searches in PubMed.

SELECTION CRITERIA

We constructed a maximum variation sample (exploring variables such as country level of development, aspects of care covered and the types of participants) from studies that had collected and analysed qualitative data related to the factors influencing implementation of doctor-nurse substitution and the expansion of nurses' tasks in community or primary care worldwide. We included perspectives of doctors, nurses, patients and their families/carers, policymakers, programme managers, other health workers and any others directly involved in or affected by the substitution. We excluded studies that collected data using qualitative methods but did not analyse the data qualitatively.

DATA COLLECTION AND ANALYSIS

We identified factors influencing implementation of doctor-nurse substitution strategies using a framework thematic synthesis approach. Two review authors independently assessed the methodological strengths and limitations of included studies using a modified Critical Appraisal Skills Programme (CASP) tool. We assessed confidence in the evidence for the QES findings using the GRADE-CERQual approach. We integrated our findings with the evidence from the effectiveness review of doctor-nurse substitution using a matrix model. Finally, we identified hypotheses for subgroup analyses for updates of the review of effectiveness.

MAIN RESULTS

We included 66 studies (69 papers), 11 from low- or middle-income countries and 55 from high-income countries. These studies found several factors that appeared to influence the implementation of doctor-nurse substitution strategies. The following factors were based on findings that we assessed as moderate or high confidence.Patients in many studies knew little about nurses' roles and the difference between nurse-led and doctor-led care. They also had mixed views about the type of tasks that nurses should deliver. They preferred doctors when the tasks were more 'medical' but accepted nurses for preventive care and follow-ups. Doctors in most studies also preferred that nurses performed only 'non-medical' tasks. Nurses were comfortable with, and believed they were competent to deliver a wide range of tasks, but particularly emphasised tasks that were more health promotive/preventive in nature.Patients in most studies thought that nurses were more easily accessible than doctors. Doctors and nurses also saw nurse-doctor substitution and collaboration as a way of increasing people's access to care, and improving the quality and continuity of care.Nurses thought that close doctor-nurse relationships and doctor's trust in and acceptance of nurses was important for shaping their roles. But nurses working alone sometimes found it difficult to communicate with doctors.Nurses felt they had gained new skills when taking on new tasks. But nurses wanted more and better training. They thought this would increase their skills, job satisfaction and motivation, and would make them more independent.Nurses taking on doctors' tasks saw this as an opportunity to develop personally, to gain more respect and to improve the quality of care they could offer to patients. Better working conditions and financial incentives also motivated nurses to take on new tasks. Doctors valued collaborating with nurses when this reduced their own workload.Doctors and nurses pointed to the importance of having access to resources, such as enough staff, equipment and supplies; good referral systems; experienced leaders; clear roles; and adequate training and supervision. But they often had problems with these issues. They also pointed to the huge number of documents they needed to complete when tasks were moved from doctors to nurses.

AUTHORS' CONCLUSIONS

Patients, doctors and nurses may accept the use of nurses to deliver services that are usually delivered by doctors. But this is likely to depend on the type of services. Nurses taking on extra tasks want respect and collaboration from doctors; as well as proper resources; good referral systems; experienced leaders; clear roles; and adequate incentives, training and supervision. However, these needs are not always met.

Targeted mentoring for human immunodeficiency virus programme support in South Africa

Background

Mentoring is a required component of health systems strengthening technical assistance interventions in low- and middle-income countries (LMICs). Mentoring is useful because it does not necessarily compromise service delivery and promotes the sharing of newly acquired knowledge and skills. However, there is a lack of research on the implementation of mentoring in the context of the HIV epidemic in southern Africa.

Objectives

This qualitative evaluation focussed on understanding the implementation process of targeted mentoring for clinical practice, data management and pharmacy management, at public health care facilities in South Africa; and on identifying critical factors influencing the effectiveness of mentoring as a technical assistance intervention in this context.

Methods

Purposive sampling was used to select participants from public health facilities in three South African Provinces. Participants were invited to take part in structured interviews. Datawere analysed using thematic analysis, and two core themes were identified: mentoring as knowledge and skills transfer; and mentoring as psychosocial support.

Results

In terms of knowledge and skills transfer, the sequential implementation of proactive and reactive mentoring was critical. Initial proactive mentoring involved mentors initiating training and developing professional relationships with mentees. Thereafter, a reactive mentoring phase allowed mentees to request support when required. This enabled mentors to leverage real-world problems faced by health workers to support their implementation of new knowledge and skills. The availability and accessibility of mentors alongside the relationships between mentors and mentees provided psychosocial support for health care workers which facilitated their self-efficacy in implementing new knowledge and skills.

Conclusion

These findings suggest that the success of mentoring programmes in LMICs may require specific attention to both knowledge transfer and the management of interpersonal relationships.

'They care rudely!': resourcing and relational health system factors that influence retention in care for people living with HIV in Zambia

INTRODUCTION

Despite access to free antiretroviral therapy (ART), many HIV-positive Zambians disengage from HIV care. We sought to understand how Zambian health system 'hardware' (tangible components) and 'software' (work practices and behaviour) influenced decisions to disengage from care among 'lost-to-follow-up' patients traced by a larger study on their current health status.

METHODS

We purposively selected 12 facilities, from 4 provinces. Indepth interviews were conducted with 69 patients across four categories: engaged in HIV care, disengaged from care, transferred to another facility and next of kin if deceased. We also conducted 24 focus group discussions with 158 lay and professional healthcare workers (HCWs). These data were triangulated against two consecutive days of observation conducted in each facility. We conducted iterative multilevel analysis using inductive and deductive reasoning.

RESULTS

Health system 'hardware' factors influencing patients' disengagement included inadequate infrastructure to protect privacy; distance to health facilities which costs patients time and money; and chronic understaffing which increased wait times. Health system 'software' factors related to HCWs' work practices and clinical decisions, including delayed opening times, file mismanagement, drug rationing and inflexibility in visit schedules, increased wait times, number of clinic visits, and frustrated access to care. While patients considered HCWs as 'mentors' and trusted sources of information, many also described them as rude, tardy, careless with details and confidentiality, and favouring relatives. Nonetheless, unlike previously reported, many patients preferred ART over alternative treatment (eg, traditional medicine) for its perceived efficacy, cost-free availability and accompanying clinical monitoring.

CONCLUSION

Findings demonstrate the dynamic effect of health system 'hardware' and 'software' factors on decisions to disengage. Our findings suggest a need for improved: physical resourcing and structuring of HIV services, preservice and inservice HCWs and management training and mentorship programmes to encourage HCWs to provide 'patient-centered' care and exercise 'flexibility' to meet patients' varying needs and circumstances.

Couples' voluntary HIV counseling and testing provider training evaluation, Zambia

With the expansion of couples' voluntary HIV counseling and testing (CVCT) in urban Zambia, there is a growing need to evaluate CVCT provider trainings to ensure that couples are receiving quality counseling and care. We evaluated provider knowledge scores, pre- and post-training and predictors of pre- and post-training test scores. Providers operating in 67 government clinics in four Copperbelt Province cities were trained from 2008 to 2013 in three domains: counseling, rapid HIV laboratory testing and data management. Trainees received pre- and post-training tests on domain-specific topics. Pre- and post-training test scores were tabulated by provider demographics and training type, and paired t-tests evaluated differences in pre- and post-training test scores. Multivariable ANCOVA determined predictors of pre- and post-training test scores. We trained 1226 providers, and average test scores increased from 68.8% pre-training to 83.8% post-training (p < 0.001). Test scores increased significantly for every demographic group and training type (p < 0.001) with one exception-test scores did not significantly increase for those receiving counseling or data management training who had less than a high school education. In multivariable analysis, higher educational level and having a medical background were predictive of a higher pre-test score; higher pre-test scores and having a medical background were predictive of higher post-test scores. Pre- and post-test assessments are critical to ensure quality services, particularly as task-shifting from medical to lay staff becomes more common. Assessments showed that our CVCT trainings are successful at increasing knowledge, and that those with lower education may benefit from repeat trainings.

Pathways of care for HIV infected children in Beira, Mozambique: pre-post intervention study to assess impact of task shifting

Background

In 2013, Mozambique implemented task-shifting (TS) from clinical officers to maternal and child nurses to improve care for HIV positive children < 5 years old. A retrospective, pre-post intervention study was designed to evaluate effectiveness of a new pathway of care in a sample of Beira District Local Health Facilities (LHFs), the primary, local, community healthcare services.

Methods

The study was conducted by accessing registries of At Risk Children Clinics (ARCCs) and HIV Health Services. Two time periods, pre- and post-intervention, were compared using a set of endpoints. Variables distribution was explored using descriptive statistics. T-student, Mann Whitney and Chi-square tests were used for comparisons.

Results

Overall, 588 HIV infected children (F = 51.4%) were recruited, 330 belonging to the post intervention period. The mean time from referral to ARCC until initiation of ART decreased from 2.3 (± 4.4) to 1.1 (± 5.0) months after the intervention implementation (p-value: 0.000). A significant increase of Isoniazid prophylaxis (O.R.: 2.69; 95%CI: 1.7–4.15) and a decrease of both regular nutritional assessment (O.R. = 0.45; 95%CI: 0.31–0.64) and CD4 count at the beginning of ART (O.R. = 0.46; 95%CI: 0.32–0.65) were documented after the intervention.

Conclusions

Despite several limitations and controversial results on nutrition assessment and CD4 count at the initiation of ART reported after the intervention, it could be assumed that TS alone may play a role in the improvement of the global effectiveness of care for HIV infected children only if integrated into a wider range of public health measures.

Mobilizing Community Health Workers to Address Mental Health Disparities for Underserved Populations: A Systematic Review

This systematic review evaluates efforts to date to involve community health workers (CHWs) in delivering evidence-based mental health interventions to underserved communities in the United States and in low- and middle-income countries. Forty-three articles (39 trials) were reviewed to characterize the background characteristics of CHW, their role in intervention delivery, the types of interventions they delivered, and the implementation supports they received. The majority of trials found that CHW-delivered interventions led to symptom reduction. Training CHWs to support the delivery of evidence-based practices may help to address mental health disparities. Areas for future research as well as clinical and policy implications are discussed.

Improved HIV and TB Knowledge and Competence Among Mid-level Providers in a Cluster-Randomized Trial of One-on-One Mentorship for Task Shifting

INTRODUCTION

Health worker shortages pose a challenge to the scale up of HIV care and treatment in Uganda. Training mid-level providers (MLPs) in the provision of HIV and tuberculosis (TB) treatment can expand existing health workforce capacity and access to HIV services.

METHODS

We conducted a cluster-randomized trial of on-site clinical mentorship for HIV and TB care at 10 health facilities in rural Uganda. Twenty MLPs at 5 randomly assigned to an intervention facilities received 8 hours a week of one-on-one mentorship, every 6 weeks over a 9-month period; and another 20 at 5 control facilities received no clinical mentorship. Enrolled MLPs' clinical knowledge and competence in management of HIV and TB was assessed using case scenarios and clinical observation at baseline and immediately after the 9-month intervention. The performance of the study health facilities on 8 TB and HIV care indicators was tracked over the 9-month period using facility patient records.

RESULTS

Thirty-nine out 40 enrolled MLPs had case scenario and clinical observation scores for both the baseline and end of intervention assessments. Mentorship was associated with a mean score increase of 16.7% (95% confidence interval: 9.8 to 23.6, P < 0.001) for the case scenario assessments and 25.9% (95% confidence interval: 14.4 to 37.5, P < 0.001) for the clinical observations. On-site clinical mentorship was significantly associated with an overall improvement for 5 of the 8 health facility TB and HIV indicators tracked.

CONCLUSIONS

One-on-one on-site mentorship improves individual knowledge and competence, has a downstream effect on facility performance, and is a simple approach to training MLPs for task shifting.

Cost-effectiveness of implementing the chronic care model for HIV care in Uganda

Objective

The chronic care model (CCM) is an integrated, population-based approach for treating those with chronic diseases that involves patient self-management, delivery system design and decision support for clinicians to ensure evidence-based care. We sought to determine effectiveness and cost-effectiveness of implementing the CCM for HIV care in Uganda.

Design

This controlled, pre/post-intervention study used difference-in-differences analysis to evaluate effectiveness of the CCM to improve patient adherence to antiretroviral therapy (ART) and CD4 counts.

Setting

One district hospital and two smaller facilities each in one intervention and one control district in Uganda.

Participants

About 46 randomly sampled patients receiving HIV services at three control sites and 56 patients from three intervention sites.

Intervention

Two group training sessions and monthly coaching visits from improvement experts over 1 year, implementing the CCM.

Main Outcome Measure(s)

Patient adherence to ART prescriptions (pill counts) and CD4 counts were measured at baseline and en dline.

Results

The odds of increased CD4 in the intervention group was 3.2 times higher than controls (P = 0.022). Clinician-reported ART adherence was 60% (P = 0.001) higher in the intervention group. The intervention cost $11 740 and served 7016 patients ($1.67 per patient). Incremental cost-effectiveness ratios of the intervention compared to business-as-usual was $6.90 per additional patient with improved CD4 and $3.40 per additional ART patient with stable or improved adherence.

Conclusion

For modest expenditure, it is possible to improve indicators of HIV care quality using the CCM. We recommended implementing the CCM in Uganda; it may be applicable in similar settings in other countries.

Task-shifting point-of-care CD4+ testing to lay health workers in HIV care and treatment services in Namibia

INTRODUCTION

Access to CD4+ testing remains a common barrier to early initiation of antiretroviral therapy among persons living with HIV/AIDS in low- and middle-income countries. The feasibility of task-shifting of point-of-care (POC) CD4+ testing to lay health workers in Namibia has not been evaluated.

METHODS

From July to August 2011, Pima CD4+ analysers were used to improve access to CD4+ testing at 10 selected public health facilities in Namibia. POC Pima CD4+ testing was performed by nurses or lay health workers. Venous blood samples were collected from 10% of patients and sent to centralised laboratories for CD4+ testing with standard methods. Outcomes for POC Pima CD4+ testing and patient receipt of results were compared between nurses and lay health workers and between the POC method and standard laboratory CD4+ testing methods.

RESULTS

Overall, 1429 patients received a Pima CD4+ test; 500 (35.0%) tests were performed by nurses and 929 (65.0%) were performed by lay health workers. When Pima CD4+ testing was performed by a nurse or a lay health worker, 93.2% and 95.2% of results were valid (p = 0.1); 95.6% and 98.1% of results were received by the patient (p = 0.007); 96.2% and 94.0% of results were received by the patient on the same day (p = 0.08). Overall, 97.2% of Pima CD4+ results were received by patients, compared to 55.4% of standard laboratory CD4+ results (p < 0.001).

CONCLUSIONS

POC CD4+ testing was feasible and effective when task-shifted to lay health workers. Rollout of POC CD4+ testing via task-shifting can improve access to CD4+ testing and retention in care between HIV diagnosis and antiretroviral therapy initiation in low- and middle-income countries.

Impact of pharmacy worker training and deployment on access to essential medicines for children under five in Malawi: a cluster quasi-experimental evaluation

BACKGROUND

Poor access to essential medicines is common in many low- and middle-income countries, partly due to an insufficient and inadequately trained workforce to manage the medicines supply chain. We conducted a prospective impact evaluation of the training and deployment of pharmacy assistants (PAs) to rural health centers in Malawi.

METHODS

A quasi-experimental design was used to compare access to medicines in two districts where newly trained PAs were deployed to health centers (intervention) and two districts with no trained PAs at health centers (comparison). A baseline household survey and two annual post-intervention household surveys were conducted. We studied children under five years with a history of fever, cough and difficulty in breathing, and diarrhea in the previous two weeks. We collected data on access to antimalarials, antibiotics and oral rehydration salts (ORS) during the childrens' symptomatic periods. We used difference-in-differences regression models to estimate the impact of PA training and deployment on access to medicines.

RESULTS

We included 3974 children across the three rounds of annual surveys: 1840 (46%) in the districts with PAs deployed at health centers and 2096 (53%) in districts with no PAs deployed at health centers. Approximately 80% of children had a fever, nearly 30% had a cough, and 43% had diarrhea in the previous two weeks. In the first year of the program, the presence of a PA led to a significant 74% increase in the odds of access to any antimalarial, and a significant 49% increase in the odds of access to artemisinin combination therapies. This effect was restricted to the first year post-intervention. There was no effect of presence of a PA on access to antibiotics or ORS.

CONCLUSION

The training and deployment of pharmacy assistants to rural health centers in Malawi increased access to antimalarial medications over the first year, but the effect was attenuated over the second year. Pharmacy assistants training and deployment demonstrated no impact on access to antibiotics for pneumonia or oral rehydration salts for diarrhea.

Global Burden of Skin Disease: Inequities and Innovations

PURPOSE OF REVIEW

We review the current understanding of the burden of dermatological disease through the lens of the Global Burden of Disease project, evaluate the impact of skin disease on quality of life in a global context, explore socioeconomic implications, and finally summarize interventions towards improving quality of dermatologic care in resource-poor settings.

RECENT FINDINGS

The Global Burden of Disease project has shown that skin diseases continue to be the 4th leading cause of nonfatal disease burden world-wide. However, research efforts and funding do not match with the relative disability of skin diseases. International and national efforts, such as the WHO List of Essential Medicines, are critical towards reducing the socioeconomic burden of skin diseases and increasing access to care. Recent innovations such as teledermatology, point-of-care diagnostic tools, and task-shifting help to provide dermatological care to underserved regions in a cost-effective manner.

SUMMARY

Skin diseases cause significant non-fatal disability worldwide, especially in resource-poor regions. Greater impetus to study the burden of skin disease in low resource settings and policy efforts towards delivering high quality care are essential in improving the burden of skin diseases.

Evaluations of training programs to improve human resource capacity for HIV, malaria, and TB control: a systematic scoping review of methods applied and outcomes assessed

BACKGROUND

Owing to the global health workforce crisis, more funding has been invested in strengthening human resources for health, particularly for HIV, tuberculosis, and malaria control; however, little is known about how these investments in training are evaluated. This paper examines how frequently HIV, malaria, and TB healthcare provider training programs have been scientifically evaluated, synthesizes information on the methods and outcome indicators used, and identifies evidence gaps for future evaluations to address.

METHODS

We conducted a systematic scoping review of publications evaluating postgraduate training programs, including in-service training programs, for HIV, tuberculosis, and malaria healthcare providers between 2000 and 2016. Using broad inclusion criteria, we searched three electronic databases and additional gray literature sources. After independent screening by two authors, data about the year, location, methodology, and outcomes assessed was extracted from eligible training program evaluation studies. Training outcomes evaluated were categorized into four levels (reaction, learning, behavior, and results) based on the Kirkpatrick model.

FINDINGS

Of 1473 unique publications identified, 87 were eligible for inclusion in the analysis. The number of published articles increased after 2006, with most (n = 57, 66%) conducted in African countries. The majority of training evaluations (n = 44, 51%) were based on HIV with fewer studies focused on malaria (n = 28, 32%) and TB (n = 23, 26%) related training. We found that quantitative survey of trainees was the most commonly used evaluation method (n = 29, 33%) and the most commonly assessed outcomes were knowledge acquisition (learning) of trainees (n = 44, 51%) and organizational impacts of the training programs (38, 44%). Behavior change and trainees' reaction to the training were evaluated less frequently and using less robust methods; costs of training were also rarely assessed.

CONCLUSIONS

Our study found that a limited number of robust evaluations had been conducted since 2000, even though the number of training programs has increased over this period to address the human resource shortage for HIV, malaria, and TB control. Specifically, we identified a lack evaluation studies on TB- and malaria-related healthcare provider training and very few studies assessing behavior change of trainees or costs of training. Developing frameworks and standardized evaluation methods may facilitate strengthening of the evidence base to inform policies on and investments in training programs.

Patient and Provider Satisfaction With a Comprehensive Strategy to Improve Prevention of Mother-to-Child HIV Transmission Services in Rural Nigeria

BACKGROUND

High mother-to-child HIV transmission rates in Nigeria are coupled with a critical shortage of trained health personnel, dearth of infrastructure, and low levels of male involvement in HIV care. This study evaluated maternal and provider satisfaction with services for prevention of mother-to-child transmission within the context of an implementation science cluster-randomized trial that included task shifting to lower-cadre workers, male engagement, point-of-care CD4 cell counts, and integrated mother-infant care.

METHODS

Patient and clinician satisfaction were measured at 6 control and 6 intervention sites using a 5-point Likert scale. Patient satisfaction was assessed at 6 weeks postpartum through a 22-item scale about the provider's ability to explain the health problem, time spent with the clinician, and motivation to follow prescribed treatment. Provider satisfaction was assessed through a 12-item scale about motivation, compensation, and training, with 4 additional questions about the impact of task shifting on job satisfaction to intervention arm providers.

RESULTS

We measured satisfaction among 340 mothers (intervention n = 160; control n = 180) and 60 providers (intervention n = 36; control n = 24). Total patient satisfaction (maximum 5) was higher in the intervention than control arm [median (interquartile range) = 4.61 (4.22-4.79) vs. 3.84 (3.22-4.22), respectively; P < 0.001]. Provider satisfaction was generally high, and was similar between the intervention and the control arms [median (interquartile range) = 3.60 (3.37-3.91) vs. 3.50 (3.08-4.25), respectively; P = 0.69]. Provider satisfaction dropped when questions on newly acquired provider roles were included [3.47 (3.25-3.72)]. Patient and provider satisfaction were not associated with uptake of antiretroviral therapy or mother-infant retention at 6 and 12 weeks postpartum.

CONCLUSIONS

Satisfaction was higher among patients at intervention sites, and provider satisfaction decreased when newly assigned roles were factored in. Task shifting should include training and supportive oversight to ensure comfort with assigned tasks.

The potential of task-shifting in scaling up services for prevention of mother-to-child transmission of HIV: a time and motion study in Dar es Salaam, Tanzania

BACKGROUND

In many African countries, prevention of mother-to-child transmission of HIV (PMTCT) services are predominantly delivered by nurses. Although task-shifting is not yet well established, community health workers (CHWs) are often informally used as part of PMTCT delivery. According to the 2008 World Health Organization (WHO) Task-shifting Guidelines, many PMTCT tasks can be shifted from nurses to CHWs.

METHODS

The aim of this time and motion study in Dar es Salaam, Tanzania, was to estimate the potential of task-shifting in PMTCT service delivery to reduce nurses' workload and health system costs. The time used by nurses to accomplish PMTCT activities during antenatal care (ANC) and postnatal care (PNC) visits was measured. These data were then used to estimate the costs that could be saved by shifting tasks from nurses to CHWs in the Tanzanian public-sector health system.

RESULTS

A total of 1121 PMTCT-related tasks carried out by nurses involving 179 patients at ANC and PNC visits were observed at 26 health facilities. The average time of the first ANC visit was the longest, 54 (95% confidence interval (CI) 42-65) min, followed by the first PNC visit which took 29 (95% CI 26-32) minutes on average. ANC and PNC follow-up visits were substantially shorter, 15 (95% CI 14-17) and 13 (95% CI 11-16) minutes, respectively. During both the first and the follow-up ANC visits, 94% of nurses' time could be shifted to CHWs, while 84% spent on the first PNC visit and 100% of the time spent on the follow-up PNC visit could be task-shifted. Depending on CHW salary estimates, the cost savings due to task-shifting in PMTCT ranged from US$ 1.3 to 2.0 (first ANC visit), US$ 0.4 to 0.6 (ANC follow-up visit), US$ 0.7 to 1.0 (first PNC visit), and US$ 0.4 to 0.5 (PNC follow-up visit).

CONCLUSIONS

Nurses working in PMTCT spend large proportions of their time on tasks that could be shifted to CHWs. Such task-shifting could allow nurses to spend more time on specialized PMTCT tasks and can substantially reduce the average cost per PMTCT patient.

Modifications to ART service delivery models by health facilities in Uganda in promotion of intervention sustainability: a mixed methods study

BACKGROUND

In November 2015, WHO released new treatment guidelines recommending that all diagnosed as HIV positive be enrolled on antiretroviral therapy (ART). Sustaining and expanding ART scale-up programs in resource-limited settings will require adaptations and modifications to traditional ART delivery models to meet the rapid increase in demand. We identify modifications to ART service delivery models by health facilities in Uganda to sustain ART interventions over a 10-year period (2004-2014).

METHODS

A mixed methods approach involving two study phases was adopted. In the first phase, a survey of a nationally representative sample of health facilities (n = 195) in Uganda which were accredited to provide ART between 2004 and 2009 was conducted. The second phase involved semi-structured interviews (n = 18) with ART clinic managers of 6 of the 195 health facilities purposively selected from the first study phase. We adopted a thematic framework consisting of four categories of modifications (format, setting, personnel, and population).

RESULTS

The majority of health facilities 185 (95%) reported making modifications to ART interventions between 2004 and 2014. Of the 195 health facilities, 157 (81%) rated the modifications made to ART as "major." Modifications to ART were reported under all the four themes. The quantitative and qualitative findings are integrated and presented under four themes. Format: Reducing the frequency of clinic appointments and pharmacy-only refill programs was identified as important strategies for decongesting ART clinics.

SETTING

Home-based care programs were introduced to reduce provider ART delivery costs. Personnel: Task shifting to non-physician cadre was reported in 181 (93%) of the health facilities.

POPULATION

Visits to the ART clinic were rationalized in favor of the sub-population deemed to have more clinical need. Two health facilities focused on patients living nearer the health facilities to align with targets set by external donors.

CONCLUSIONS

Over the study period, health facilities made several modifications ART interventions to improve fit with their resource-constrained settings thereby promoting long-term sustainability. Further research evaluating the effect of these modifications on patient outcomes and ART delivery costs is recommended. Our findings have implications for the sustainability of ART scale-up programs in Uganda and other resource-limited settings.

Facilitators and Barriers of Community-Level Quality Improvement for Maternal and Newborn Health in Tanzania

A quality improvement intervention for maternal and newborn health was carried out in southern Tanzania at the community level. It sought to improve health-seeking behaviors and uptake of community-level maternal and newborn health practices. A process evaluation populated using data primarily from in-depth interviews and focus group discussions with the intervention's implementers was undertaken in four villages receiving the intervention to evaluate the intervention's implementation, uncover facilitators and barriers of quality improvement, and highlight contextual factors that might have influenced implementation. Performance implementation scores were used to rank the villages. Identifying higher- and lower-performing villages highlighted key facilitators and barriers of community-level quality improvement related to support from local leaders, motivation through use of local quality improvement data, and regular education around quality improvement and maternal and newborn health. These findings can be taken formatively in the design of similar interventions in the future.

Patient engagement in HIV care and treatment in Zambia, 2004-2014

OBJECTIVE

To describe engagement along the HIV continuum of care using a large network of clinics in Zambia.

METHODS

We employed a practical framework to describe retention along the HIV treatment cascade, using routinely collected clinical data available in resource-constrained settings. We included health facilities in four Zambian provinces with more than 300 enrolled patients over the age of 5 years. We described attrition at each step, from HIV enrolment to 720 days after ART initiation. The population was further stratified by year of enrolment to describe temporal trends in patient engagement.

RESULTS

From January 2004 to December 2014, 444 439 individuals over the age of 5 years sought HIV care at 75 eligible health facilities. Among those enrolled into HIV care, 82.1% (95% confidence interval [CI]: 79.4-84.5%) were fully assessed for ART eligibility within 180 days of enrolment and 63.6% (95% CI: 61.7-65.3) were found to be eligible for ART based on the HIV treatment guidelines at the time. Of those patients eligible for ART, 81.1% (95% CI: 79.5-82.7%) initiated ART within 180 days. Patient retention in ART programme was 81.2% (95% CI: 80.4-81.9%) at 90 days, 70.0% (95% CI: 68.7-71.2%) at 360 days and 61.6% (95% CI: 60.0-63.2%) at 720 days. We noted a steady decline in proportions assessed for ART eligibility and deemed eligible for ART in the time frame. Proportions that started ART and remained in care remained relatively consistent.

CONCLUSION

We describe a simple approach for assessing patient engagement after enrolment into HIV care. Using limited types of data routinely available, we demonstrate an important and replicable approach to monitoring programmes in resource-constrained settings.

Human resources for health strategies adopted by providers in resource-limited settings to sustain long-term delivery of ART: a mixed-methods study from Uganda

BACKGROUND

Human resources for health (HRH) constraints are a major barrier to the sustainability of antiretroviral therapy (ART) scale-up programs in Sub-Saharan Africa. Many prior approaches to HRH constraints have taken a top-down trend of generalized global strategies and policy guidelines. The objective of the study was to examine the human resources for health strategies adopted by front-line providers in Uganda to sustain ART delivery beyond the initial ART scale-up phase between 2004 and 2009.

METHODS

A two-phase mixed-methods approach was adopted. In the first phase, a survey of a nationally representative sample of health facilities (n = 195) across Uganda was conducted. The second phase involved in-depth interviews (n = 36) with ART clinic managers and staff of 6 of the 195 health facilities purposively selected from the first study phase. Quantitative data was analysed based on descriptive statistics, and qualitative data was analysed by coding and thematic analysis.

RESULTS

The identified strategies were categorized into five themes: (1) providing monetary and non-monetary incentives to health workers on busy ART clinic days; (2) workload reduction through spacing ART clinic appointments; (3) adopting training workshops in ART management as a motivation strategy for health workers; (4) adopting non-physician-centred staffing models; and (5) devising ART program leadership styles that enhanced health worker commitment.

CONCLUSIONS

Facility-level strategies for responding to HRH constraints are feasible and can contribute to efforts to increase country ownership of HIV programs in resource-limited settings. Consideration of the human resources for health strategies identified in the study by ART program planners and managers could enhance the long-term sustainment of ART programs by providers in resource-limited settings.

Healthcare Professional Shortage and Task-Shifting to Prevent Cardiovascular Disease: Implications for Low- and Middle-Income Countries

Cardiovascular diseases (CVD) account for 18 million of annual global deaths with more than three quarters of these deaths occurring in low- and middle-income countries (LMIC). In LMIC, the distribution of risk factors is heterogeneous, with urban areas being the worst affected. Despite the availability of effective CVD interventions in developed countries, many poor countries still struggle to provide care due to lack of resources. In addition, many LMIC suffer from staff shortages which pose additional burden to the healthcare system. Regardless of these challenges, there are potentially effective strategies such as task-shifting which have been used for chronic conditions such as HIV to address the human resource crisis. We propose that through task-shifting, certain tasks related to prevention be shifted to non-physician health workers as well as non-nurse health workers such as community health workers. Such steps will allow better coverage of segments of the underserved population. We recognise that for task-shifting to be effective, issues such as clearly defined roles, evaluation, on-going training, and supervision must be addressed.

Can Disease-Specific Funding Harm Health? in the Shadow of HIV/AIDS Service Expansion

This article examines the effect of introducing a new HIV/AIDS service-prevention of mother-to-child transmission of HIV (PMTCT)-on overall quality of prenatal and postnatal care. My results suggest that local PMTCT introduction in Zambia may have actually increased all-cause child mortality in the short term. There is some evidence that vaccinations may have declined in the short term in association with local PMTCT introduction, suggesting that the new service may have partly crowded out existing pediatric health services.

A qualitative review of implementer perceptions of the national community-level malaria surveillance system in Southern Province, Zambia

Background

Parts of Zambia with very low malaria parasite prevalence and high coverage of vector control interventions are targeted for malaria elimination through a series of interventions including reactive case detection (RCD) at community level. When a symptomatic individual presenting to a community health worker (CHW) or government clinic is diagnostically confirmed as an incident malaria case an RCD response is initiated. This consists of a CHW screening the community around the incident case with rapid diagnostic tests (RDT) and treating positive cases with artemether-lumefantrine (AL, Coartem™) in accordance with national policy. Since its inception in 2011, Zambia’s RCD programme has relied on anecdotal feedback from staff to identify issues and possible solutions. In 2014, a systematic qualitative programme review was conducted to determine perceptions around malaria rates, incentives, operational challenges and solutions according to CHWs, their supervisors and district-level managers.

Methods

A criterion-based sampling framework based on training regime and performance level was used to select nine rural health posts in four districts of Southern Province. Twenty-two staff interviews were completed to produce English or bilingual (CiTonga or Silozi + English) verbatim transcripts, which were then analysed using thematic framework analysis.

Results

CHWs, their supervisors and district-level managers strongly credited the system with improving access to malaria services and significantly reducing the number of cases in their area. The main implementation barriers included access (e.g., lack of rain gear, broken bicycles), insufficient number of CHWs for programme coverage, communication (e.g. difficulties maintaining cell phones and “talk time” to transmit data by phone), and inconsistent supply chain (e.g., inadequate numbers of RDT kits and anti-malarial drugs to test and treat uncomplicated cases).

Conclusions

This review highlights the importance of a community surveillance system like RCD in shaping Zambia’s malaria elimination campaign by identifying community-based infections that might otherwise remain undetected. At this stage the system must ensure it can meet growing public demand by providing CHWs the tools and materials they need to consistently carry out their work and expand programme reach to more isolated communities. Results from this review will be used to plan programme scale-up into other parts of Zambia.

The impact of leadership hubs on the uptake of evidence-informed nursing practices and workplace policies for HIV care: a quasi-experimental study in Jamaica, Kenya, Uganda and South Africa

BACKGROUND

The enormous impact of HIV on communities and health services in Sub-Saharan Africa and the Caribbean has especially affected nurses, who comprise the largest proportion of the health workforce in low- and middle-income countries (LMICs). Strengthening action-based leadership for and by nurses is a means to improve the uptake of evidence-informed practices for HIV care.

METHODS

A prospective quasi-experimental study in Jamaica, Kenya, Uganda and South Africa examined the impact of establishing multi-stakeholder leadership hubs on evidence-informed HIV care practices. Hub members were engaged through a participatory action research (PAR) approach. Three intervention districts were purposefully selected in each country, and three control districts were chosen in Jamaica, Kenya and Uganda. WHO level 3, 4 and 5 health care institutions and their employed nurses were randomly sampled. Self-administered, validated instruments measured clinical practices (reports of self and peers), quality assurance, work place policies and stigma at baseline and follow-up. Standardised average scores ranging from 0 to 1 were computed for clinical practices, quality assurance and work place policies. Stigma scores were summarised as 0 (no reports) versus 1 (one or more reports). Pre-post differences in outcomes between intervention and control groups were compared using the Mantel Haenszel chi-square for dichotomised stigma scores, and independent t tests for other measures. For South Africa, which had no control group, pre-post differences were compared using a Pearson chi-square and independent t test. Multivariate analysis was completed for Jamaica and Kenya. Hub members in all countries self-assessed changes in their capacity at follow-up; these were examined using a paired t test.

RESULTS

Response rates among health care institutions were 90.2 and 80.4 % at baseline and follow-up, respectively. Results were mixed. There were small but statistically significant pre-post, intervention versus control district improvements in workplace policies and quality assurance in Jamaica, but these were primarily due to a decline in scores in the control group. There were modest improvements in clinical practices, workplace policies and quality assurance in South Africa (pre-post) (clinical practices of self-pre 0.67 (95 % CI, 0.62, 0.72) versus post 0.78 (95 % CI, 0.73-0.82), p = 0.002; workplace policies-pre 0.82 (95 % CI, 0.70, 0.85) versus post 0.87 (95 % CI, 0.84, 0.90), p = 0.001; quality assurance-pre 0.72 (95 % CI, 0.67, 0.77) versus post 0.84 (95 % CI, 0.80, 0.88)). There were statistically significant improvements in scores for nurses stigmatising patients (Jamaica reports of not stigmatising-pre-post intervention 33.9 versus 62.4 %, pre-post control 54.7 versus 64.4 %, p = 0.002-and Kenya pre-post intervention 35 versus 51.6 %, pre-post control 34.2 versus 47.8 %, p = 0.006) and for nurses being stigmatised (Kenya reports of no stigmatisation-pre-post intervention 23 versus 37.3 %, pre-post control 15.4 versus 27 %, p = 0.004). Multivariate results for Kenya and Jamaica were non-significant. Twelve hubs were established; 11 were active at follow-up. Hub members (n = 34) reported significant improvements in their capacity to address care gaps.

CONCLUSIONS

Leadership hubs, comprising nurses and other stakeholders committed to change and provided with capacity building can collectively identify issues and act on strategies that may improve practice and policy. Overall, hubs did not provide the necessary force to improve the uptake of evidence-informed HIV care in their districts. If hubs are to succeed, they must be integrated within district health authorities and become part of formal, legal organisations that can regularise and sustain them.

Successes and Challenges of HIV Mentoring in Malawi: The Mentee Perspective

HIV clinical mentoring has been utilized for capacity building in Africa, but few formal program evaluations have explored mentee perspectives on these programs. EQUIP is a PEPFAR-USAID funded program in Malawi that has been providing HIV mentoring on clinical and health systems since 2010. We sought to understand the successes and challenges of EQUIP’s mentorship program. From June-September 2014 we performed semi-structured, in-depth interviews with EQUIP mentees who had received mentoring for ≥ 1 year. Interview questions focused on program successes and challenges and were performed in English, audio recorded, coded, and analyzed using inductive content analysis with ATLAS.ti v7. Fifty-two mentees from 32 health centers were interviewed. The majority of mentees were 18–40 years old (79%, N = 41), 69% (N = 36) were male, 50% (N = 26) were nurses, 29% (N = 15) medical assistants, and 21% (N = 11) clinical officers. All mentees felt that EQUIP mentorship was successful (100%, N = 52). The most common benefit reported was an increase in clinical knowledge allowing for initiation of antiretroviral therapy (33%, N = 17). One-third of mentees (N = 17) reported increased clinic efficiency and improved systems for patient care due to EQUIP’s systems mentoring including documentation, supply chain and support for minor construction at clinics. The most common challenge (52%, N = 27) was understaffing at facilities, with mentees having multiple responsibilities during mentorship visits resulting in impaired ability to focus on learning. Mentees also reported that medication stock-outs (42%, N = 22) created challenges for the mentoring process. EQUIP’s systems-based mentorship and infrastructure improvements allowed for an optimized environment for clinical training. Shortages of health workers at sites pose a challenge for mentoring programs because mentees are pulled from learning experiences to perform non-HIV-related clinic duties. Evaluations of existing mentoring models are needed to continue to improve mentoring strategies that result in sustainable benefits for mentees, facilities, and patients.

Assessment of activities performed by clinical nurse practitioners and implications for staffing and patient care at primary health care level in South Africa

Background

The shortage of nurses in public healthcare facilities in South Africa is well documented; finding creative solutions to this problem remains a priority.

Objective

This study sought to establish the amount of time that clinical nurse practitioners (CNPs) in one district of the Western Cape spend on clinical services and the implications for staffing and skills mix in order to deliver quality patient care.

Methods

A descriptive cross-sectional study was conducted across 15 purposively selected clinics providing primary health services in 5 sub-districts. The frequency of activities and time CNPs spent on each activity in fixed and mobile clinics were recorded. Time spent on activities and health facility staff profiles were correlated and predictors of the total time spent by CNPs with patients were identified.

Results

The time spent on clinical activities was associated with the number of CNPs in the facilities. CNPs in fixed clinics spent a median time of about 13 minutes with each patient whereas CNPs in mobile clinics spent 3 minutes. Fixed-clinic CNPs also spent more time on their non-core functions than their core functions, more time with patients, and saw fewer patients compared to mobile-clinic CNPs.

Conclusions

The findings give insight into the time CNPs in rural fixed and mobile clinics spend with their patients, and how patient caseload may affect consultation times. Two promising strategies were identified – task shifting and adjustments in health worker deployment – as ways to address staffing and skills mix, which skills mix creates the potential for using healthcare workers fully whilst enhancing the long-term health of these rural communities.

Integrated prevention of mother-to-child HIV transmission services, antiretroviral therapy initiation, and maternal and infant retention in care in rural north-central Nigeria: a cluster-randomised controlled trial

BACKGROUND

Antiretroviral therapy (ART) and retention in care are essential for the prevention of mother-to-child HIV transmission (PMTCT). We aimed to assess the effect of a family-focused, integrated PMTCT care package.

METHODS

In this parallel, cluster-randomised controlled trial, we pair-matched 12 primary and secondary level health-care facilities located in rural north-central Nigeria. Clinic pairs were randomly assigned to intervention or standard of care (control) by computer-generated sequence. HIV-infected women (and their infants) presenting for antenatal care or delivery were included if they had unknown HIV status at presentation (there was no age limit for the study, but the youngest participant was 16 years old); history of antiretroviral prophylaxis or treatment, but not receiving these at presentation; or known HIV status but had never received treatment. Standard of care included health information, opt-out HIV testing, infant feeding counselling, referral for CD4 cell counts and treatment, home-based services, antiretroviral prophylaxis, and early infant diagnosis. The intervention package added task shifting, point-of-care CD4 testing, integrated mother and infant service provision, and male partner and community engagement. The primary outcomes were the proportion of eligible women who initiated ART and the proportion of women and their infants retained in care at 6 weeks and 12 weeks post partum (assessed by generalised linear mixed effects model with random effects for matched clinic pairs). The trial is registered with ClinicalTrials.gov, number NCT01805752.

FINDINGS

Between April 1, 2013, and March 31, 2014, we enrolled 369 eligible women (172 intervention, 197 control), similar across groups for marital status, duration of HIV diagnosis, and distance to facility. Median CD4 count was 424 cells per μL (IQR 268-606) in the intervention group and 314 cells per μL (245-406) in the control group (p<0·0001). Of the 369 women included in the study, 363 (98%) had WHO clinical stage 1 disease, 364 (99%) had high functional status, and 353 (96%) delivered vaginally. Mothers in the intervention group were more likely to initiate ART (166 [97%] vs 77 [39%]; adjusted relative risk 3·3, 95% CI 1·4-7·8). Mother and infant pairs in the intervention group were more likely to be retained in care at 6 weeks (125 [83%] of 150 vs 15 [9%] of 170; adjusted relative risk 9·1, 5·2-15·9) and 12 weeks (112 [75%] of 150 vs 11 [7%] of 168 pairs; 10·3, 5·4-19·7) post partum.

INTERPRETATION

This integrated, family-focused PMTCT service package improved maternal ART initiation and mother and infant retention in care. An effective approach to improve the quality of PMTCT service delivery will positively affect global goals for the elimination of mother-to-child HIV transmission.

HIV Prevention in Resource Limited Settings: A Case Study of Challenges and Opportunities for Implementation

BACKGROUND

Sub-Saharan Africa has the highest global prevalence of HIV, and the prevention of transmission between HIV-seropositive and -serodiscordant sexual partners is a critical component of HIV prevention efforts. Behavioral interventions that have demonstrated efficacy in reducing risk behaviors associated with HIV transmission and infection and have been translated, or adapted, to a variety of settings.

PURPOSE

This manuscript examined implementation of behavioral interventions within resource limited health care delivery settings, and their adoption and integration within service programs to achieve sustainability.

METHODS

The CDC/Partner Program, an evidence-based risk reduction intervention, was implemented in Community Health Centers (CHCs) in Zambia using a staged technology transfer process, the Training the Trainers Model. Provincial workshops and training workshops on the provision of the intervention were used to establish a cadre of trainers to provide on-site intervention facilitators capable of ultimately providing coverage to over 300 CHCs.

RESULTS

CHC staff provided the intervention to clinic attendees in four provinces over 4 years while also training new facilitators. The implementation process addressed multi-level issues within the context of training, consultants, decision making, administration, and evaluation as well as practical considerations surrounding travel, training, staff compensation and ongoing quality assurance.

CONCLUSIONS

The majority of challenges to implementation and maintenance were addressed and resolved, with the exception of structural limitations related to restricted resources for personnel and funding. Strengths of the program included its collaborative structure, active program leadership, commitment and support at the provincial level, the use of task shifting by existing clinic staff, the train the trainer model and ongoing quality control. Enhanced infrastructure is needed in for future implementation, such as training centers within each province, certified expert coaches and annual workshops and system changes to ensure available staff.

Improvement and retention of emergency obstetrics and neonatal care knowledge and skills in a hospital mentorship program in Lilongwe, Malawi

OBJECTIVE

To evaluate whether a hospital-based mentoring program could significantly increase short- and longer-term emergency obstetrics and neonatal care (EmONC) knowledge and skills among health providers.

METHODS

In a prospective before-and-after study, 20 mentors were trained using a specially-created EmONC mentoring and training program at Bwaila Hospital in Lilongwe, Malawi. The mentors then trained an additional 114 providers as mentees in the curriculum. Mentors and mentees were asked to complete a test before initiation of the training (Pre-Test), immediately after training (Post-Test 1), and at least 6 months after training (Post-Test 2) to assess written and practical EmONC knowledge and skills. Mean scores were then compared.

RESULTS

Scores increased significantly between the Pre-Test and Post-Test 1 for both written (n=134; difference 22.9%, P<0.001) and practical (n=125; difference 29.5%, P<0.001) tests. Scores were still significantly higher in Post-Test 2 than in the Pre-Test for written (n=111; difference 21.0%, P<0.001) and practical (n=103; difference 29.3%, P<0.001) tests.

CONCLUSION

A hospital-based mentoring program can result in both short- and longer-term improvement in EmONC knowledge and skills. Further research is required to assess whether this leads to behavioral changes that improve maternal and neonatal outcomes.

Task-Shifting and Quality of HIV Testing Services: Experiences from a National Reference Hospital in Zambia

BACKGROUND

With new testing technologies, task-shifting and rapid scale-up of HIV testing services in high HIV prevalence countries, assuring quality of HIV testing is paramount. This study aimed to explore various cadres of providers' experiences in providing HIV testing services and their understanding of elements that impact on quality of service in Zambia.

METHODS

Sixteen in-depth interviews and two focus group discussions were conducted with HIV testing service providers including lay counselors, nurses and laboratory personnel at purposively selected HIV testing sites at a national reference hospital in Lusaka. Qualitative content analysis was adopted for data analysis.

RESULTS

Lay counselors and nurses reported confidentiality and privacy to be greatly compromised due to limited space in both in- and out-patient settings. Difficulties in upholding consent were reported in provider-initiated testing in in-patient settings. The providers identified non-adherence to testing procedures, high workload and inadequate training and supervision as key elements impacting on quality of testing. Difficulties related to testing varied by sub-groups of providers: lay counselors, in finger pricking and obtaining adequate volumes of specimen; non-laboratory providers in general, in interpreting invalid, false-negative and false-positive results. The providers had been participating in a recently established national HIV quality assurance program, i.e. proficiency testing, but rarely received site supervisory visits.

CONCLUSION

Task-shifting coupled with policy shifts in service provision has seriously challenged HIV testing quality, protection of confidentiality and the process of informed consent. Ways to better protect confidentiality and informed consent need careful attention. Training, supervision and quality assurance need strengthening tailored to the needs of the different cadres of providers.

IAPAC Guidelines for Optimizing the HIV Care Continuum for Adults and Adolescents

BACKGROUND

An estimated 50% of people living with HIV (PLHIV) globally are unaware of their status. Among those who know their HIV status, many do not receive antiretroviral therapy (ART) in a timely manner, fail to remain engaged in care, or do not achieve sustained viral suppression. Barriers across the HIV care continuum prevent PLHIV from achieving the therapeutic and preventive effects of ART.

METHODS

A systematic literature search was conducted, and 6132 articles, including randomized controlled trials, observational studies with or without comparators, cross-sectional studies, and descriptive documents, met the inclusion criteria. Of these, 1047 articles were used to generate 36 recommendations to optimize the HIV care continuum for adults and adolescents.

RECOMMENDATIONS

Recommendations are provided for interventions to optimize the HIV care environment; increase HIV testing and linkage to care, treatment coverage, retention in care, and viral suppression; and monitor the HIV care continuum.

Tracing defaulters in HIV prevention of mother-to-child transmission programmes through community health workers: results from a rural setting in Zimbabwe

Introduction

High retention in care is paramount to reduce vertical human immunodeficiency virus (HIV) infections in prevention of mother-to-child transmission (PMTCT) programmes but remains low in many sub-Saharan African countries. We aimed to assess the effects of community health worker–based defaulter tracing (CHW-DT) on retention in care and mother-to-child HIV transmission, an innovative approach that has not been evaluated to date.

Methods

We analyzed patient records of 1878 HIV-positive pregnant women and their newborns in a rural PMTCT programme in the Tsholotsho district of Zimbabwe between 2010 and 2013 in a retrospective cohort study. Using binomial regression, we compared vertical HIV transmission rates at six weeks post-partum, and retention rates during the perinatal PMTCT period (at delivery, nevirapine [NVP] initiation at three days post-partum, cotrimoxazole (CTX) initiation at six weeks post-partum, and HIV testing at six weeks post-partum) before and after the introduction of CHW-DT in the project.

Results

Median maternal age was 27 years (inter-quartile range [IQR] 23 to 32) and median CD4 count was 394 cells/µL³ (IQR 257 to 563). The covariate-adjusted rate ratio (aRR) for perinatal HIV transmission was 0.72 (95% confidence intervals [95% CI] 0.27 to 1.96, p=0.504), comparing patient outcomes after and before the intervention. Among fully retained patients, 11 (1.9%) newborns tested HIV positive. ARRs for retention in care were 1.01 (95% CI 0.96 to 1.06, p=0.730) at delivery; 1.35 (95% CI 1.28 to 1.42, p<0.001) at NVP initiation; 1.78 (95% CI 1.58 to 2.01, p<0.001) at CTX initiation; and 2.54 (95% CI 2.20 to 2.93, p<0.001) at infant HIV testing. Cumulative retention after and before the intervention was 496 (85.7%) and 1083 (87.3%) until delivery; 480 (82.9%) and 1005 (81.0%) until NVP initiation; 303 (52.3%) and 517 (41.7%) until CTX initiation; 272 (47.0%) and 427 (34.4%) until infant HIV testing; and 172 (29.7%) and 405 (32.6%) until HIV test result collection.

Conclusions

The CHW-DT intervention did not reduce perinatal HIV transmission significantly. Retention improved moderately during the post-natal period, but cumulative retention decreased rapidly even after the intervention. We showed that transmission in resource-limited settings can be as low as in resource-rich countries if patients are fully retained in care. This requires structural changes to the regular PMTCT services, in which community health workers can, at best, play a complementary role.

Task shifting in surgery: Lessons from an Indian Heart Hospital

We present a case study that illustrates task shifting, the transfer of activities from senior to junior colleagues, in the context of cardiac surgery at the Narayana Health City Cardiac Hospital (NH) in India. The case discusses the factors driving the adoption of task shifting at NH and identifies the implications of task shifting for surgeon training, surgical capacity, and procedure costs. A comparison of the outcomes of two senior surgeons with similar experience, workload, and patient profiles--but varying in their level of task shifting--suggests that shifting of lower complexity tasks by senior surgeons to trained junior colleagues does not negatively impact in-hospital mortality and post-procedure length of stay. The study concludes with a discussion of task shifting's potential to improve access to affordable tertiary care in resource-constrained settings.

Trends in task shifting in HIV treatment in Africa: Effectiveness, challenges and acceptability to the health professions

BACKGROUND

Task shifting has been suggested to meet the demand for initiating and managing more patients on antiretroviral therapy. Although the idea of task shifting is not new, it acquires new relevance in the context of current healthcare delivery.

AIM

To appraise current trends in task shifting related to HIV treatment programmes in order to evaluate evidence related to the effectiveness of this strategy in addressing human resource constraints and improving patient outcomes, challenges identified in practice and the acceptability of this strategy to the health professions.

METHOD

Electronic databases were searched for studies published in English between January 2009 and December 2014. Keywords such as 'task shifting', 'HIV treatment', 'human resources' and 'health professions' were used.

RESULTS

Evidence suggests that task shifting is an effective strategy for addressing human resource constraints in healthcare systems in many countries and provides a cost-effective approach without compromising patient outcomes. Challenges include inadequate supervision support and mentoring, absent regulatory frameworks, a lack of general health system strengthening and the need for monitoring and evaluation. The strategy generally seems to be accepted by the health professions although several arguments against task shifting as a long-term approach have been raised.

CONCLUSION

Task shifting occurs in many settings other than HIV treatment programmes and is viewed as a key strategy for governing human resources for healthcare. It may be an opportune time to review current task shifting recommendations to include a wider range of programmes and incorporate initiatives to address current challenges.

Integrated clinical and quality improvement coaching in Son La Province, Vietnam: a model of building public sector capacity for sustainable HIV care delivery

Background

The global scale-up of antiretroviral therapy included extensive training and onsite support to build the capacity of HIV health care workers. However, traditional efforts aimed at strengthening knowledge and skills often are not successful at improving gaps in the key health systems required for sustaining high quality care.

Methods

We trained and mentored existing staff of the Son La provincial health department and provincial HIV clinic to work as a provincial coaching team (PCT) to provide integrated coaching in clinical HIV skills and quality improvement (QI) to the HIV clinics in the province. Nine core indicators were measured through chart extraction by clinic and provincial staff at baseline and at 6 month intervals thereafter. Coaching from the team to each of the clinics, in both QI and clinical skills, was guided by results of performance measurements, gap analyses, and resulting QI plans.

Results

After 18 months, the PCT had successfully spread QI activities, and was independently providing regular coaching to the provincial general hospital clinic and six of the eight district clinics in the province. The frequency and type of coaching was determined by performance measurement results. Clinics completed a mean of five QI projects. Quality of HIV care was improved throughout all clinics with significant increases in seven of the indicators. Overall both the PCT activities and clinic performance were sustained after integration of the model into the Vietnam National QI Program.

Conclusions

We successfully built capacity of a team of public sector health care workers to provide integrated coaching in both clinical skills and QI across a province. The PCT is a feasible and effective model to spread and sustain quality activities and improve HIV care services in a decentralized rural setting.
