Health Professions Education Strategies for Enhancing Capacity for Task-Shifting and Task-Sharing Implementation in Africa: A Scoping Review

INTRODUCTION

To compensate for the shortage of health workers and effectively use the available health workforce to provide access to health services at various levels of the health system, several countries are implementing task-shifting and task-sharing (TSTS). This scoping review was conducted to synthesize evidence on health professions education (HPE) strategies applied to enhance capacities for TSTS implementation in Africa.

METHODS

This scoping review was conducted using the enhanced Arksey and O'Malley's framework for scoping reviews. The sources of evidence included CINAHL, PubMed, and Scopus.

RESULTS

Thirty-eight studies conducted in 23 countries provided insights on the strategies implemented in various health services contexts including general health, cancer screenings, reproductive, maternal, newborn, child and adolescent health, HIV/AIDS, emergency care, hypertension, tuberculosis, eye care, diabetes, mental health, and medicines. The HPE strategies applied were in-service training, onsite clinical supervision and mentoring, periodic supportive supervision, provision of job aides, and preservice education.

DISCUSSION

Scaling up HPE based on the evidence from this study will contribute immensely to enhancing the capacity of health workers in contexts where TSTS are being implemented or planned to provide quality health services based on the population's health needs.

Task Shifting and Task Sharing Implementation in Africa: A Scoping Review on Rationale and Scope

Numerous studies have reported task shifting and task sharing due to various reasons and with varied scopes of health services, either task-shifted or -shared. However, very few studies have mapped the evidence on task shifting and task sharing. We conducted a scoping review to synthesize evidence on the rationale and scope of task shifting and task sharing in Africa. We identified peer-reviewed papers from PubMed, Scopus, and CINAHL bibliographic databases. Studies that met the eligibility criteria were charted to document data on the rationale for task shifting and task sharing, and the scope of tasks shifted or shared in Africa. The charted data were thematically analyzed. Sixty-one studies met the eligibility criteria, with fifty-three providing insights on the rationale and scope of task shifting and task sharing, and seven on the scope and one on rationale, respectively. The rationales for task shifting and task sharing were health worker shortages, to optimally utilize existing health workers, and to expand access to health services. The scope of health services shifted or shared in 23 countries were HIV/AIDS, tuberculosis, hypertension, diabetes, mental health, eyecare, maternal and child health, sexual and reproductive health, surgical care, medicines' management, and emergency care. Task shifting and task sharing are widely implemented in Africa across various health services contexts towards ensuring access to health services.

Exploring inter- and intra-organisational dynamics supporting task-shifting opportunities in AIDS service organisations: A qualitative study

Task-shifting of combination sexual health services from clinicians to community workers has been well-studied in low-resource settings, but lacks empirical examination as a response to service inequities in North American community-based AIDS service organisations (ASOs). This study adopts a qualitative exploratory approach to understanding how ASOs may support task-shifting for gay, bisexual and other men who have sex with men (GBMSM), drawing from interviews (n = 33) with clinicians and community workers in southern Ontario. Results include intra-organisational (including resource supports, development of community worker roles, providing task-shifting training, provider representation and inclusive service environment) and inter-organisational (including structure of engagement, streamlining referrals, development of effective partnerships, development of a formal organisational network and increasing awareness) dynamics which, when applied at an organisation level within ASOs, encourage successful and effective task-shifting. Related activities may be used to increase service quality and access for GBMSM. Considerations for application and management practice is provided.

Identifying models of HIV care and treatment service delivery in Tanzania, Uganda, and Zambia using cluster analysis and Delphi survey

BACKGROUND

Organization of HIV care and treatment services, including clinic staffing and services, may shape clinical and financial outcomes, yet there has been little attempt to describe different models of HIV care in sub-Saharan Africa (SSA). Information about the relative benefits and drawbacks of different models could inform the scale-up of antiretroviral therapy (ART) and associated services in resource-limited settings (RLS), especially in light of expanded client populations with country adoption of WHO's test and treat recommendation.

METHODS

We characterized task-shifting/task-sharing practices in 19 diverse ART clinics in Tanzania, Uganda, and Zambia and used cluster analysis to identify unique models of service provision. We ran descriptive statistics to explore how the clusters varied by environmental factors and programmatic characteristics. Finally, we employed the Delphi Method to make systematic use of expert opinions to ensure that the cluster variables were meaningful in the context of actual task-shifting of ART services in SSA.

RESULTS

The cluster analysis identified three task-shifting/task-sharing models. The main differences across models were the availability of medical doctors, the scope of clinical responsibility assigned to nurses, and the use of lay health care workers. Patterns of healthcare staffing in HIV service delivery were associated with different environmental factors (e.g., health facility levels, urban vs. rural settings) and programme characteristics (e.g., community ART distribution or integrated tuberculosis treatment on-site).

CONCLUSIONS

Understanding the relative advantages and disadvantages of different models of care can help national programmes adapt to increased client load, select optimal adherence strategies within decentralized models of care, and identify differentiated models of care for clients to meet the growing needs of long-term ART patients who require more complicated treatment management.

Uptake and predictors of early postnatal follow-up care amongst mother-baby pairs in South Africa: Results from three population-based surveys, 2010-2013

BACKGROUND

Achieving World Health Organization (WHO) recommendations for postnatal care (PNC) within the first few weeks of life is vital to eliminating early mother-to-child transmission of HIV (MTCT) and improving infant health. Almost half of the annual global deaths among children under five occur during the first six weeks of life. This study aims to identify uptake of three PNC visits within the first six weeks of life as recommended by WHO among South African mother-infant pairs, and factors associated with uptake.

METHODS

We analyzed data from three facility-based, nationally representative surveys (2010, 2011/12 and 2012/13) primarily designed to determine the effectiveness of the South African program to prevent MTCT. This analysis describes the proportion of infants achieving the WHO recommendation of at least 3 PNC visits. Interviews from 27 699 HIV-negative and HIV-positive mothers of infants aged 4-8 weeks receiving their six week immunization were included in analysis. Data were analyzed using STATA 13.0 and weighted for sample ascertainment and South African live births. We fitted a multivariable logistic regression model to estimate factors associated with early PNC uptake.

RESULTS

Over half (59.6%, 95% confidence interval (CI) = 59.0-60.3) of mother-infant pairs received the recommended three PNC visits during the first 6 weeks; uptake was 63.1% (95% CI = 61.9-64.3) amongst HIV exposed infants and 58.1% (95% CI = 57.3-58.9) amongst HIV unexposed infants. Uptake of early PNC improved significantly with each survey, but varied significantly by province. Multivariable analysis of the pooled data, controlling for survey year, demonstrated that number of antenatal visits (4+ vs <4 Adjusted odds ratio (aOR) = 1.13, 95% CI = 1.04-1.23), timing of initial antenatal visits (≤12 weeks vs >12 weeks, aOR = 1.13, 95% CI = 1.04-1.23), place of delivery (clinic vs hospital aOR = 1.5, 1.3-1.6), and infant HIV exposure (exposed vs unexposed aOR = 1.2, 95% CI = 1.1-1.2) were the key factors associated with receiving recommended PNC visits.

CONCLUSIONS

Approximately 40% of neonates did not receive three or more postnatal care visits in the first 6 weeks of life from 2010-2013. To improve uptake of early PNC, early antenatal booking, more frequent antenatal care attendance, and attention to HIV negative women is needed.

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.

"It is always HIV/AIDS and TB": Home-based carers' perspectives on epilepsy in Cape Town, South Africa

The study highlights the complex cultural religious factors affecting epilepsy and a need for integrated home-based care services. Two focus group discussions exploring home-based carers’ (HBCs) perspectives on epilepsy were conducted using a semi-structured focus group interview guide, which was based on Kleinman's explanatory model framework. The audio-recorded data were transcribed verbatim, and a thematic analysis was done. The three main themes were epilepsy names and metaphors, religious beliefs about the cause and treatment of epilepsy, and HBCs’ perceived roles and strategies for engaging in epilepsy care. Findings provide some insights for research, policy, and practice.

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.

Evaluation of the HIV lay counselling and testing profession in South Africa

BACKGROUND

With the launch of the national HIV Counselling and Testing (HCT) campaign in South Africa (SA), lay HIV counsellors, who had been trained in blood withdrawal, have taken up the role of HIV testing. This study evaluated the experiences, training, motivation, support, supervision, and workload of HIV lay counsellors and testers in South Africa. The aim was to identify gaps in their resources, training, supervision, motivation, and workload related to HCT services. In addition it explored their experiences with providing HIV testing under the task shifting context.

METHODS

The study was conducted in eight of South Africa's nine provinces. 32 lay counsellors were recruited from 67 HCT sites, and were interviewed using two questionnaires that included structured and semi-structured questions. One questionnaire focused on their role as HIV counsellors and the other on their role as HIV testers.

RESULTS

Ninety-seven percent of counsellors reported that they have received training in counselling and testing. Many rated their training as more than adequate or adequate, with 15.6% rating it as not adequate. Respondents reported a lack of standardised counselling and testing training, and revealed gaps in counselling skills for specific groups such as discordant couples, homosexuals, older clients and children. They indicated health system barriers, including inadequate designated space for counselling, which compromises privacy and confidentiality. Lay counsellors carry the burden of counselling and testing nationally, and have other tasks such as administration and auxiliary duties due to staff shortages.

CONCLUSIONS

This study demonstrates that HCT counselling and testing services in South Africa are mainly performed by lay counsellors and testers. They are challenged by inadequate work space, limited counselling skills for specific groups, a lack of standardised training policies and considerable administrative and auxiliary duties. To improve HCT services, there needs to be training needs with a standardised curriculum and refresher courses, for HIV counselling and testing, specifically for specific elderly clients, discordant couples, homosexuals and children. The Department of Health should formally integrate lay counsellors into the health care system with proper allocation of tasks under the task shifting policy.

TB/HIV-related training, knowledge and attitudes of community health workers in the Free State province, South Africa

With its emphasis on task shifting and multi-trained and skilled outreach teams the primary healthcare (PHC) re-engineering strategy in South Africa depends on the training, knowledge and attitudes of community health workers (CHWs) to provide a variety of TB/HIV services. The aim of this exploratory research was to assess TB/ HIV-related training, knowledge and attitudes of CHWs. Interviews were conducted with 206 CHWs at 28 clinics in 1 urban and 2 rural sub-districts in the Free State province. Descriptive and bivariate analyses were performed using chi-square, Kruskal-Wallis (H) and Mann-Whitney (U) tests for non-parametric data. More than half (54.9%) had not received basic training in HIV counselling and testing; almost one-third (31.1%) had not received basic training in TB/directly observed treatment (DOT) support. Furthermore, most CHWs had not received any follow-up training in HIV counselling and testing and in TB/DOT support. Significant associations (0.01 < p < 0.05) between the types of CHWs and their sub-district location, and their TB/HIV-related training, knowledge and attitudes were observed. In respect of the TB/HIV knowledge items assessed, a large majority (>95%) were knowledgeable, with only a few being ignorant about important facts related to TB/HIV. Lay counsellors were significantly more knowledgeable about TB/HIV than TB/DOT supporters and other CHWs were. Most CHWs disagreed with stigmatising statements about people with TB/HIV. The sub-district location of CHWs was significantly associated with their attitudes towards people with TB/HIV. CHWs in the two rural sub-districts were more likely to agree with stigmatising statements. In the context of PHC re-engineering, this exploratory research suggests that CHW TB/HIV training, knowledge and attitudes can and need to be improved if integrated TB/HIV services are to be successfully task-shifted to them in line with policy recommendations.

Task shifting from doctors to non-doctors for initiation and maintenance of antiretroviral therapy

BACKGROUND

The high levels of healthcare worker shortage is recognised as a severe impediment to increasing patients' access to antiretroviral therapy. This is particularly of concern where the burden of disease is greatest and the access to trained doctors is limited.This review aims to better inform HIV care programmes that are currently underway, and those planned, by assessing if task-shifting care from doctors to non-doctors provides both high quality and safe care for all patients requiring antiretroviral treatment.

OBJECTIVES

To evaluate the quality of initiation and maintenance of HIV/AIDS care in models that task shift care from doctors to non-doctors.

SEARCH METHODS

We conducted a comprehensive search to identify all relevant studies regardless of language or publication status (published, unpublished, in press, and in progress) from 1 January 1996 to 28 March 2014, with major HIV/AIDS conferences searched 23 May 2014. We had also contacted relevant organizations and researchers. Key words included MeSH terms and free-text terms relevant to 'task shifting', 'skill mix', 'integration of tasks', 'service delivery' and 'health services accessibility'.

SELECTION CRITERIA

We included controlled trials (randomised or non-randomised), controlled-before and after studies, and cohort studies (prospective or retrospective) comparing doctor-led antiretroviral therapy delivery to delivery that included another cadre of health worker other than a doctor, for initiating treatment, continuing treatment, or both, in HIV infected patients.

DATA COLLECTION AND ANALYSIS

Two authors independently screened titles, abstracts and descriptor terms of the results of the electronic search and applied our eligibility criteria using a standardized eligibility form to full texts of potentially eligible or uncertain abstracts. Two reviewers independently extracted data on standardized data extraction forms. Where possible, data were pooled using random effects meta-analysis. We assessed evidence quality with GRADE methodology.

MAIN RESULTS

Ten studies met our inclusion criteria, all of which were conducted in Africa. Of these four were randomised controlled trials while the remaining six were cohort studies.From the trial data, when nurses initiated and provided follow-up HIV therapy, there was high quality evidence of no difference in death at one year, unadjusted risk ratio was 0.96 (95% CI 0.82 to 1.12), one trial, cluster adjusted n = 2770. There was moderate quality evidence of lower rates of losses to follow-up at one year, relative risk of 0.73 (95% CI 0.55 to 0.97). From the cohort data, there was low quality evidence that there may be an increased risk of death in the task shifting group, relative risk 1.23 (95% CI 1.14 to 1.33, two cohorts, n = 39 160) and very low quality data reporting no difference in patients lost to follow-up between groups, relative risk 0.30 (95% CI 0.05 to 1.94).From the trial data, when doctors initiated therapy and nurses provided follow-up, there was moderate quality evidence that there is probably no difference in death compared with doctor-led care at one year, relative risk of 0.89 (95% CI 0.59 to 1.32), two trials, cluster adjusted n = 4332. There was moderate quality evidence that there is probably no difference in the numbers of patients lost to follow-up at one year, relative risk 1.27 (95% CI 0.92 to 1.77), P = 0.15. From the cohort data, there is very low quality data that death at one year may be lower in the task shifting group, relative risk 0.19 (95% CI 0.05 to 0.78), one cohort, n = 2772, and very low quality evidence that loss to follow-up was reduced, relative risk 0.34 (95% CI 0.18 to 0.66).From the trial data, for maintenance therapy delivered in the community there was moderate quality evidence that there is probably no difference in mortality when doctors deliver care in the hospital or specially trained field workers provide home-based maintenance care and antiretroviral therapy at one year, relative risk 1.0 (95% CI 0.62 to 1.62), 1 trial, cluster adjusted n = 559. There is moderate quality evidence from this trial that losses to follow-up are probably no different at one year, relative risk 0.52 (0.12 to 2.3), P = 0.39. The cohort studies did not report on one year follow-up for these outcomes.Across the studies that reported on virological and immunological outcomes, there was no clear evidence of difference whether a doctor or nurse or clinical officer delivered therapy. Three studies report on costs to patients, indicating a reduction in travel costs to treatment facilities where task shifting was occurring closer to patients homes. There is conflicting evidence regarding the relative cost to the health system, as implementation of the strategy may increase costs. The two studies reporting the patient and staff perceptions of the quality of care, report good acceptability of the service by patients, and general acceptance by doctors of the shifting of roles. One trial reported on the time to initiation of antiretroviral therapy, finding no clear evidence of a difference between groups. The same trial reports on new diagnosis of tuberculosis which favours nurse initiation of HIV care for increasing the numbers of diagnoses of tuberculosis made.

AUTHORS' CONCLUSIONS

Our review found moderate quality evidence that shifting responsibility from doctors to adequately trained and supported nurses or community health workers for managing HIV patients probably does not decrease the quality of care and, in the case of nurse initiated care, may decrease the numbers of patients lost to follow-up.

Evaluation of a well-established task-shifting initiative: the lay counselor cadre in Botswana

Background

Evidence supports the implementation of task shifting to address health worker shortages that are common in resource-limited settings. However, there is need to learn from established programs to identify ways to achieve the strongest, most sustainable impact. This study examined the Botswana lay counselor cadre, a task shifting initiative, to explore effectiveness and contribution to the health workforce.

Methods

This evaluation used multiple methods, including a desk review, a national lay counselor survey (n = 385; response = 94%), in-depth interviews (n = 79), lay counselors focus group discussions (n = 7), lay counselors observations (n = 25), and client exit interviews (n = 47).

Results

Interview and focus group data indicate that lay counselors contribute to essentially all HIV-related programs in Botswana and they conduct the majority of HIV tests and related counseling at public health facilities throughout the country. Interviews showed that the lay counselor cadre is making the workload of more skilled health workers more manageable and increasing HIV acceptance in communities. The average score on a work-related knowledge test was 74.5%. However for 3 questions, less than half answered correctly. During observations, lay counselors demonstrated average competence for most skills assessed and clients (97.9%) were satisfied with services received. From the survey, lay counselors generally reported being comfortable with their duties; however, some reported clinical duties that extended beyond their training and mandate. Multiple factors affecting the performance of the lay counselors were identified, including insufficient resources, such as private counseling space and HIV test kits; and technical, administrative, and supervisory support.

Conclusion

Lay counselors are fulfilling an important role in Botswana's healthcare system, serving as the entry point into HIV care, support, and treatment services.

Recommendation

For this and other similar task shifting initiatives, it is important that lay counselors' responsibilities are clear and that training and support are adequate to optimize their effectiveness.

Improved survival and antiretroviral treatment outcomes in adults receiving community-based adherence support: 5-year results from a multicentre cohort study in South Africa

INTRODUCTION

A large increase in lay health care workers has occurred in response to shortages of professional health care staff in sub-Saharan African antiretroviral treatment (ART) programs. However, little effectiveness data of the large-scale implementation of these programs is available. We evaluated the effect of a community-based adherence-support (CBAS) program on ART outcomes across 57 South African sites.

METHODS

CBAS workers provide adherence and psychosocial support for patients and undertake home visits to address household challenges affecting adherence. An observational multicohort study of adults enrolling for ART between 2004 and 2010 was performed. Mortality, loss to follow-up, and virological suppression were compared by intention to treat between patients who received and did not receive CBAS until 5 years of ART, using multiple imputation of missing covariate values.

RESULTS

Of the 66,953 patients who were included, 19,668 (29.4%) patients received CBAS and 47,285 (70.6%) patients did not. Complete-case covariate data were available for 54.3% patients. After 5 years, patient retention was 79.1% [95% confidence interval (CI): 77.7% to 80.4%] in CBAS patients versus 73.6% (95% CI: 72.6% to 74.5%) in non-CBAS patients; crude hazard ratio (HR) for attrition was 0.68 (95% CI: 0.65 to 0.72). Mortality and loss to follow-up were independently lower in CBAS patients, adjusted HR (aHR) was 0.65 (95% CI: 0.59 to 0.72) and 0.63 (95% CI: 0.59 to 0.68), respectively. After 6 months of ART, virological suppression was 76.6% (95% CI: 75.8% to 77.5%) in CBAS patients versus 72% (95% CI: 71.3% to 72.5%) in non-CBAS patients (P < 0.0001), adjusted odds ratio was 1.22 (95% CI: 1.14 to 1.30). Improvement in virological suppression occurred progressively for longer durations of ART [adjusted odds ratio was 2.66 (95% CI: 1.61 to 4.40) by 5 years].

CONCLUSIONS

Patients receiving CBAS had considerably better ART outcomes. Further scale-up of these programs should be considered in low-income settings.
