Training needs assessment for clinicians at antiretroviral therapy clinics: evidence from a national survey in Uganda

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.

Alternative financing mechanisms for ART programs in health facilities in Uganda: a mixed-methods approach

Background

Sub-Saharan Africa is heavily dependent on global health initiatives (GHIs) for funding antiretroviral therapy (ART) scale-up. There are indications that global investments for ART scale-up are flattening. It is unclear what new funding channels can bridge the funding gap for ART service delivery. Many previous studies have focused on domestic government spending and international funding especially from GHIs. The objective of this study was to identify the funding strategies adopted by health facilities in Uganda to sustain ART programs between 2004 and 2014 and to explore variations in financing mechanisms by ownership of health facility.

Methods

A mixed-methods approach was employed. A survey of health facilities (N = 195) across Uganda which commenced ART delivery between 2004 and 2009 was conducted. Six health facilities were purposively selected for in-depth examination. Semi-structured interviews (N = 18) were conducted with ART Clinic managers (three from each of the six health facilities). Statistical analyses were performed in STATA (Version 12.0) and qualitative data were analyzed by coding and thematic analysis.

Results

Multiple funding sources for ART programs were common with 140 (72%) of the health facilities indicating at least two concurrent grants supporting ART service delivery between 2009 and 2014. Private philanthropic aid emerged as an important source of supplemental funding for ART service delivery. ART financing strategies were differentiated by ownership of health facility. Private not-for-profit providers were more externally-focused (multiple grants, philanthropic aid). For-profit providers were more client-oriented (fee-for-service, insurance schemes). Public facilities sought additional funding streams not dissimilar to other health facility ownership-types.

Conclusion

Over the 10-year study period, health facilities in Uganda diversified funding sources for ART service delivery. The identified alternative funding mechanisms could reduce dependence on GHI funding and increase local ownership of HIV programs. Further research evaluating the potential contribution of the identified alternative financing mechanisms in bridging the global HIV funding gap is recommended.

Effectiveness of educational outreach in infectious diseases management: a cluster randomized trial in Uganda

BACKGROUND

Integrated Infectious Diseases Capacity Building Evaluation (IDCAP) teams designed and implemented two health worker in-service training approaches: 1) an off-site classroom-based integrated management of infectious diseases (IMID) course with distance learning aspects, and 2) on-site support (OSS), an educational outreach intervention. We tested the effects of OSS on workload and 12 facility performance indicators for emergency triage assessment and treatment, HIV testing, and malaria and pneumonia case management among outpatients by two subgroups: 1) mid-level practitioners (MLP) who attended IMID training (IMID-MLP) and 2) health workers who did not (No-IMID).

METHODS

Thirty-six health facilities participated in the IDCAP trial, with 18 randomly assigned to Arm A and 18 to Arm B. Two MLP in both arms received IMID. All providers at Arm A facilities received nine monthly OSS visits from April to December 2010 while Arm B did not. From November 2009 to December 2010, 777,667 outpatient visits occurred. We analyzed 669,580 (86.1 %) outpatient visits, where provider cadre was reported. Treatment was provided by 64 IMID-MLP and 1,515 No-IMID providers. The effect of OSS was measured by the difference in pre/post changes across arms after controlling for covariates (adjusted ratio of relative risks = a RRR).

RESULTS

The effect of OSS on patients-per-provider-per-day (workload) among IMID-MLP (aRRR = 1.21; p = 0.48) and No-IMID (aRRR = 0.90; p = 0.44) was not statistically significant. Among IMID-MLP, OSS was effective for three indicators: malaria cases receiving an appropriate antimalarial (aRRR = 1.26, 99 % CI = 1.02-1.56), patients with negative malaria test result prescribed an antimalarial (aRRR = 0.49, 99 % CI = 0.26-0.92), and patients with acid-fast bacilli smear negative result receiving empiric treatment for acute respiratory infection (aRRR = 2.04, 99 % CI = 1.06-3.94). Among No-IMID, OSS was effective for two indicators: emergency and priority patients admitted, detained or referred (aRRR = 2.12, 99 % CI = 1.05-4.28) and emergency patients receiving at least one appropriate treatment (aRRR = 1.98, 99 % CI = 1.21-3.24).

CONCLUSION

Effects of OSS on workload were not statistically significant. Significant OSS effects on facility performance across subgroups were heterogeneous. OSS supported MLP who diagnosed and treated patients to apply IMID knowledge. For other providers, OSS supported team work to manage emergency patients. This evidence on OSS effectiveness could inform interventions to improve health workers' capacity to deliver better quality infectious diseases care.

Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians

Responding to critical shortages of physicians, most sub-Saharan countries have scaled up training of non-physician clinicians (NPCs), resulting in a gradual but decisive shift to NPCs as the cornerstone of healthcare delivery. This development should unfold in parallel with strategic rethinking about the role of physicians and with innovations in physician education and in-service training. In important ways, a growing number of NPCs only renders physicians more necessary - for example, as specialized healthcare providers and as leaders, managers, mentors, and public health administrators. Physicians in sub-Saharan Africa ought to be trained in all of these capacities. This evolution in the role of physicians may also help address known challenges to the successful integration of NPCs in the health system.

Effect of integrated infectious disease training and on-site support on the management of childhood illnesses in Uganda: a cluster randomized trial

Background

The Integrated Infectious Disease Capacity-Building Evaluation (IDCAP) was designed to test the effects of two interventions, Integrated Management of Infectious Disease (IMID) training and on-site support (OSS), on clinical practice of mid-level practitioners. This article reports the effects of these interventions on clinical practice in management of common childhood illnesses.

Methods

Two trainees from each of 36 health facilities participated in the IMID training. IMID was a three-week core course, two one-week boost courses, and distance learning over nine months. Eighteen of the 36 health facilities were then randomly assigned to arm A, and participated in OSS, while the other 18 health facilities assigned to arm B did not. Clinical faculty assessed trainee practice on clinical practice of six sets of tasks: patient history, physical examination, laboratory tests, diagnosis, treatment, and patient/caregiver education. The effects of IMID were measured by the post/pre adjusted relative risk (aRR) of appropriate practice in arm B. The incremental effects of OSS were measured by the adjusted ratio of relative risks (aRRR) in arm A compared to arm B. All hypotheses were tested at a 5 % level of significance.

Results

Patient samples were comparable across arms at baseline and endline. The majority of children were aged under five years; 84 % at baseline and 97 % at endline. The effects of IMID on patient history (aRR = 1.12; 95 % CI = 1.04-1.21) and physical examination (aRR = 1.40; 95 % CI = 1.16-1.68) tasks were statistically significant. OSS was associated with incremental improvement in patient history (aRRR = 1.18; 95 % CI = 1.06-1.31), and physical examination (aRRR = 1.27; 95 % CI = 1.02-1.59) tasks. Improvements in laboratory testing, diagnosis, treatment, and patient/caregiver education were not statistically significant.

Conclusion

IMID training was associated with improved patient history taking and physical examination, and OSS further improved these clinical practices. On-site training and continuous quality improvement activities support transfer of learning to practice among mid-level practitioners.

Readiness of Ugandan health services for the management of outpatients with chronic diseases

OBJECTIVE

Traditionally, health systems in sub-Saharan Africa have focused on acute conditions. Few data exist on the readiness of African health facilities (HFs) to address the growing burden of chronic diseases (CDs), specifically chronic, non-communicable diseases (NCDs).

METHODS

A stratified random sample of 28 urban and rural Ugandan HFs was surveyed to document the burden of selected CDs by analysing the service statistics, service availability and service readiness using a modified WHO Service Availability and Readiness Assessment questionnaire. Knowledge, skills and practice in the management of CDs of 222 health workers were assessed through a self-completed questionnaire.

RESULTS

Among adult outpatient visits at hospitals, 33% were for CDs including HIV vs. 14% and 4% at medium-sized and small health centres, respectively. Many HFs lacked guidelines, diagnostic equipment and essential medicines for the primary management of CDs; training and reporting systems were weak. Lower-level facilities routinely referred patients with hypertension and diabetes. HIV services accounted for most CD visits and were stronger than NCD services. Systems were weaker in lower-level HFs. Non-doctor clinicians and nurses lacked knowledge and experience in NCD care.

CONCLUSION

Compared with higher level HFs, lower-level ones are less prepared and little used for CD care. Health systems in Uganda, particularly lower-level HFs, urgently need improvement in managing common NCDs to cope with the growing burden. This should include the provision of standard guidelines, essential diagnostic equipment and drugs, training of health workers, supportive supervision and improved referral systems. Substantially better HIV basic service readiness demonstrates that improved NCD care is feasible.

Access to antiretroviral treatment, issues of well-being and public health governance in Chad: what justifies the limited success of the universal access policy?

Universal access to antiretroviral treatment (ART) in Chad was officially declared in December 2006. This presidential initiative was and is still funded 100% by the country's budget and external donors' financial support. Many factors have triggered the spread of AIDS. Some of these factors include the existence of norms and beliefs that create or increase exposure, the low-level education that precludes access to health information, social unrest, and population migration to areas of high economic opportunities and gender-based discrimination. Social forces that influence the distribution of dimensions of well-being and shape risks for infection also determine the persistence of access barriers to ART. The universal access policy is quite revolutionary but should be informed by the systemic barriers to access so as to promote equity. It is not enough to distribute ARVs and provide health services when health systems are poorly organized and managed. Comprehensive access to ART raises many organizational, ethical and policy problems that need to be solved to achieve equity in access. This paper argues that the persistence of access barriers is due to weak health systems and a poor public health leadership. AIDS has challenged health systems in a manner that is essentially different from other health problems.

Advances in clinical education: a model for infectious disease training for mid-level practitioners in Uganda

Advances in health professional education have been slow to materialize in many developing countries over the past half-century, contributing to a widening gap in quality of care compared to developed countries. Recent calls for reform in global health professional education have stressed, among other priorities, the need for approaches that strengthen clinical reasoning skills. While the development of these skills is critical to enhance health systems, little research has been carried out on the effectiveness of applying these strategies in the context of severe human resource shortages and complex disease presentations. Integrated Infectious Disease Capacity Building Evaluation (IDCAP) based at the Infectious Diseases Institute at Makerere University created a training program using current best practices in clinical education to support the development of complex reasoning skills among clinicians in rural Uganda. Over a period of 9 months, the program integrated classroom and clinic-based training approaches and measured indicators of success with particular reference to common infectious diseases. This article describes in detail the IDCAP approach to integrating advances in health professional education theory in the context of an overburdened, inadequately resourced primary health care system; results from the evaluation are expected in 2012.

Policy and programmatic implications of task shifting in Uganda: a case study

BACKGROUND

Uganda has a severe health worker shortage and a high demand for health care services. This study aimed to assess the policy and programmatic implications of task shifting in Uganda.

METHODS

This was a qualitative, descriptive study through 34 key informant interviews and eight (8) focus group discussions, with participants from various levels of the health system.

RESULTS

Policy makers understood task shifting, but front-line health workers had misconceptions on the meaning and intention(s) of task shifting. Examples were cited of task shifting within the Ugandan health system, some formalized (e.g. psychiatric clinical officers), and some informal ones (e.g. nurses inserting IV lines and initiating treatment). There was apparently high acceptance of task shifting in HIV/AIDS service delivery, with involvement of community health workers (CHW) and PLWHA in care and support of AIDS patients.There was no written policy or guidelines on task shifting, but the policy environment was reportedly conducive with plans to develop a policy and guidelines on task shifting.Factors favouring task shifting included successful examples of task shifting, proper referral channels, the need for services, scarcity of skills and focused initiatives such as home based management of fever. Barriers to task shifting included reluctance to change, protection of professional turf, professional boundaries and regulations, heavy workload and high disease burden, poor planning, lack of a task shifting champion, lack of guidelines, the name task shifting itself, and unemployed health professionals.There were both positive and negative views on task shifting: the positive ones cast task shifting as one of the solutions to the dual problem of lack of skills and high demand for service, and as something that is already happening; while negative ones saw it as a quick fix intended for the poor, a threat to quality care and likely to compromise the health system.

CONCLUSION

There were widespread examples of task in Uganda, and task shifting was mainly attributed to HRH shortages coupled with the high demand for healthcare services. There is need for clear policy and guidelines to regulate task shifting and protect those who undertake delegated tasks.

A single-blind randomized controlled trial to evaluate the effect of extended counseling on uptake of pre-antiretroviral care in Eastern Uganda

Background

Many newly screened people living with HIV (PLHIV) in Sub-Saharan Africa do not understand the importance of regular pre-antiretroviral (ARV) care because most of them have been counseled by staff who lack basic counseling skills. This results in low uptake of pre-ARV care and late treatment initiation in resource-poor settings. The effect of providing post-test counseling by staff equipped with basic counseling skills, combined with home visits by community support agents on uptake of pre-ARV care for newly diagnosed PLHIV was evaluated through a randomized intervention trial in Uganda.

Methods

An intervention trial was performed consisting of post-test counseling by trained counselors, combined with monthly home visits by community support agents for continued counseling to newly screened PLHIV in Iganga district, Uganda between July 2009 and June 2010, Participants (N = 400) from three public recruitment centres were randomized to receive either the intervention, or the standard care (the existing post-test counseling by ARV clinic staff who lack basic training in counseling skills), the control arm. The outcome measure was the proportion of newly screened and counseled PLHIV in either arm who had been to their nearest health center for clinical check-up in the subsequent three months +2 months. Treatment was randomly assigned using computer-generated random numbers. The statistical significance of differences between the two study arms was assessed using chi-square and t-tests for categorical and quantitative data respectively. Risk ratios and 95% confidence intervals were used to assess the effect of the intervention.

Results

Participants in the intervention arm were 80% more likely to accept (take up) pre-ARV care compared to those in the control arm (RR 1.8, 95% CI 1.4-2.1). No adverse events were reported.

Conclusions

Provision of post-test counseling by staff trained in basic counseling skills, combined with home visits by community support agents had a significant effect on uptake of pre-ARV care and appears to be a cost-effective way to increase the prerequisites for timely ARV initiation.

Trial registration

The trial was registered by Current Controlled Trials Ltd C/OBioMed Central Ltd as ISRCTN94133652 and received financial support from Sida and logistical support from the European Commission.

Inadequate pre-antiretroviral care, stock-out of antiretroviral drugs and stigma: policy challenges/bottlenecks to the new WHO recommendations for earlier initiation of antiretroviral therapy (CD<350 cells/microL) in eastern Uganda

OBJECTIVE

This study explores reasons for late ART initiation among known HIV positive persons in care from a client/caretaker perspective in eastern Ugandan where ART awareness is presumably high yet AIDS related mortality is a common function of late initiation of ARVs.

METHODS

In Iganga, Uganda we conducted in-depth interviews with clients who started ART at 50-200 CD4 cells/microL and those initiated very late at CD4<50 cells/microL. Focus-group discussions were also conducted with caretakers of clients on ART. Content analysis was performed to identify recurrent themes.

RESULTS

ARV stock-outs, inadequate pre-antiretroviral care and lack of staff confidentiality were system barriers to timely ART initiation. Weak social support and prevailing stigma and misconceptions about ARVs as drugs designed to kill, cause cancer, infertility or impotence were other important factors.

CONCLUSION

If the new WHO recommendations (start ART at CD4 350 cells/microL) should be feasible, PLHIV/communities need sensitization about the importance of regular pre-ARV care through the local media and authorities. The ARV supply chain and staff attitudes towards client confidentiality must also be improved in order to encourage timely ART initiation. PLHIV/communities should be sensitization about drug package labeling and the use and importance of ARVs. Stronger social support structures must be created through public messages that fight stigma, enhance acceptance of PLHIV and encourage timely ART initiation.
