HIV Pre-Exposure Prophylaxis Uptake Among High-Risk Population in Sub-Saharan Africa: A Systematic Review and Meta-Analysis

Globally, 38.4 million people are affected by the human immunodeficiency virus (HIV) pandemic, and more than 2.5 million new HIV infections occur yearly. HIV pre-exposure prophylaxis (PrEP) has been widely recognized as a potential way to prevent new infections among risk population. There is a paucity of abridged evidence on the level and barriers to PrEP service uptake in sub-Saharan Africa (SSA). Therefore, we conducted a systematic review to synthesize existing evidence on PrEP uptake in SSA. Relevant studies were searched from major databases (PubMed and PsychInfo) and direct Google Scholar. Data were extracted and recorded using a pilot-tested template. Methodological rigor, heterogeneity and publication bias of studies were assessed to minimize the inclusion of erroneous findings. A random effect model was used for the meta-analysis followed by narrative metasynthesis. The protocol of this systematic review has been by registered PROSPERO (ID: CRD42022308855). A total of 1830 studies were retrieved, and 30 studies met inclusion criteria of the systematic review. People who heard about PrEP ranged from 23% to 98%. The pooled prevalence of willingness to use PrEP was 64.2% (95% confidence interval: 55.5-72.0). Fear of side effect, stigma, nonreceptive attitude, cost of pills, low awareness about PrEP, perceived reason about the effectiveness of PrEP, and lack of friendly services were the common barriers to PrEP uptake in Africa. In conclusion, comprehensive knowledge and willingness to use PrEP were low in SSA. The barriers to low PrEP service uptake are avoidable through comprehensive awareness creation and availing essential services to key population in Africa. Expanding educational messages to key population using friendly approaches and more accessible platforms, engaging stakeholders, and integrating PrEP service with routine health care are important to foster HIV prevention and control in the future.

Policymakers' and healthcare providers' perspectives on the introduction of oral pre-exposure prophylaxis for key populations in Ghana

BACKGROUND

Key populations (KPs) such as female sex workers (FSWs), men who have sex with men (MSM), people who inject drugs (PWID), and their partners contribute more than a quarter (27.5%) of new HIV infection in Ghana. Oral pre-exposure prophylaxis (PrEP) can substantially reduce HIV acquisition among this group. While the available research indicates KPs willingness to take PrEP in Ghana, little is known about the position of policymakers and healthcare providers on the introduction of PrEP for KPs.

METHODS

Qualitative data were collected from September to October 2017 in the Greater Accra (GA) and Brong-Ahafo (BA) regions of Ghana. Key informant interviews were conducted with 20 regional and national policymakers and supplemented with In-depth Interviews with 23 healthcare providers to explore their level of support for PrEP and their perspectives on challenges and issues to consider for oral PrEP implementation in Ghana. Thematic content analysis was used to unearth the issues emerging from the interviews.

RESULTS

Policymakers and healthcare providers in both regions expressed strong support for introducing PrEP for KPs. Key concerns regarding oral PrEP introduction included potential for behavioral disinhibition, non-adherence and side effects of medication, cost and long-term financial implications, and stigma related to HIV and key populations. Participants stressed the need to integrate PrEP into existing services and the provision of PrEP should start with high risk groups like sero-discordant couples, FSWs and MSM.

CONCLUSIONS

Policymakers and providers recognize the value of PrEP in cubing new HIV infections but have concerns about disinhibition, non-adherence, and cost. Therefore, the Ghana health service should roll-out a range of strategies to address their concerns including: sensitization with providers to mitigate underlying stigma towards KPs, particularly MSM, integration of PrEP into existing services, and innovative strategies to improve continued use of PrEP.

Perspectives of Policymakers on the Introduction and Scale-Up of HIV Self-Testing and Implication for National HIV Programming in Ghana

Background: HIV self-testing (HIVST) has the potential to greatly increase HIV testing uptake, particularly among key populations (KPs) at higher risk for HIV. Studies have shown high acceptability and feasibility of HIVST among various target populations globally. However, less is known about the perspectives of policymakers, who are critical to the success of HIVST implementation. Their views on barriers to the introduction and scale-up of self-testing are critical to understand in order for HIVST to become part of the national HIV guidelines. We sought to understand policymakers' perspectives of challenges and facilitators to the introduction of HIVST at the client and structural levels.

Method: Key informant interviews (KIIs) were conducted with national and regional level policymakers involved in the HIV response. Twenty policymakers were purposively selected from Greater Accra (capital) and Brong-Ahafo (outlying) regions. Qualitative content analysis was used to arrive at the results after the verbatim transcripts were coded.

Results: Client-level challenges included lack of pre-test counseling, the need for confirmatory testing if reactive, potential for poor linkage to care and treatment, and client-level facilitator from policy makers' perspectives included increase testing modality that would increase testing uptake. Structural-level challenges mentioned by policymakers were lack of a national policy and implementation guidelines on HIVST, cost of HIVST kits, supply chain management of HIVST commodities, data monitoring and reporting of positive cases. The structural-level appeal of HIVST to policymakers were the reduced burden on health system and HIVST's contribution to achieving testing targets. Despite the challenges mentioned, policymakers unanimously favored and called for the introduction of HIVST in Ghana.

Conclusions: Findings indicate that a non-conventional HIV testing strategy such as HIVST is highly acceptable to policymakers. However, successful introduction of HIVST hinges on having national guidelines in place and stakeholder consultations to address various individual and structural -level implementation issues.

Perceptions of Ghanaian traditional health practitioners, primary health care workers, service users and caregivers regarding collaboration for mental health care

BACKGROUND

In low- and middle-income countries, the paucity of conventional health services means that many people with mental health problems rely on traditional health practitioners (THPs). This paper examines the possibility of forging partnerships at the Primary Health Care (PHC) level in two geopolitical regions of Ghana, to maximize the benefits to both health systems.

METHODS

The study was a qualitative cross-sectional survey. Eight (8) focus group discussions (FGDs) were conducted between February and April 2014. The views of THPs, PHC providers, service users (i.e. patients) and their caregivers, on the perceived benefits, barriers and facilitators of forging partnerships were examined. A thematic framework approach was employed for analysis.

RESULTS

The study revealed that underlying the widespread approval of forging partnerships, there were mutual undertones of suspicion. While PHC providers were mainly concerned that THPs may incur harms to service users (e.g., through delays in care pathways and human rights abuses), service users and their caregivers highlighted the failure of conventional medical care to meet their healthcare needs. There are practical challenges to these collaborations, including the lack of options to adequately deal with human rights issues such as some patients being chained and exposed to the vagaries of the weather at THPs. There is also the issue of the frequent shortage of psychotropic medication at PHCs.

CONCLUSION

Addressing these barriers could enhance partnerships. There is also a need to educate all providers, which should include sessions clarifying the potential value of such partnerships.

"Making the Mentally Ill Count", lessons from a Health and Demographic Surveillance System for people with mental and neurological disorders in the Kintampo districts of Ghana

Background

Persons with mental and neurological disorders (PMNDs) are among the most marginalised groups in developing countries, as they are socially excluded and overlooked in most developmental efforts. Due to high levels of stigma and other operational difficulties, PMNDs are often marginalised in routine enumeration exercises. Health and Demographic Surveillance System is an important public health research platform especially in countries that lacks reliable data systems, as it registers and monitor basic demographic and health events such as births, deaths and migration in a geographically defined population. This information is essential for policy development and resource distribution and service delivery. We aim to document the reasons for not counting PMNDs in our communities and demonstrate the usefulness of the Kintampo Health and Demographic Surveillance Systems (KHDSS) platform in counting PMNDs over time. We also documented strategies in providing vital information that helps in establishing the rights of PMNDs.

Methods

As a longitudinal study, psychiatric case register was established. Both quantitative and qualitative data collection techniques were used to solicit responses from stakeholders regarding the non-consideration of PMNDs as part of household membership in the study area. PMNDs were identified using the KHDSS and followed every 6 months. The “targeted” (actively searching for PMNDs) and “service provision” (providing medical treatment for PMNDs) approaches were adopted to enhance the identification of PMNDs.

Results

Stigma was the main reason cited for the non-counting of PMNDs in the area. Following a “targeted” and “service provision” approach, the number of PMNDs enrolled into the psychiatric case register went up to 68% in 2010; as against the previous levels of 49 and 54% in 2005 and 2008 respectively. The study highlights the intrinsic value of such an approach for social inclusion of PMNDs.

Conclusions

Stigma against PMNDs was report in this study. We provided evidence that the KHDSS platform is useful for identification of PMNDs for service provision. The paper highlights evidence for policy formulation and implementation.

Cumulative effects of heat exposure and storage conditions of Oxytocin-in-Uniject in rural Ghana: implications for scale up

Oxytocin-in-Uniject devices could be stored 30 to 40 days without refrigeration under typical field conditions, with wastage levels below 10%, based on simulation studies.

Objective:

Postpartum hemorrhage can be reduced substantially in home deliveries attended by community-based workers by using Oxytocin-in-Uniject (OIU) devices affixed with temperature-time indicators. We characterized the distribution of time to discard of these devices when stored under normal field conditions in Ghana.

Methods:

Two drug storage simulation studies were conducted in rural Ghana in 2011 and 2012. Devices were transported under refrigeration from manufacture (Argentina) to storage at the study site. Twenty-three field workers each stored at home (unrefrigerated) 25 OIU devices and monitored them daily to record: (1) time to transition from usable to unusable, and (2) continuous digital ambient temperature to determine heat exposure over the simulation period. Time to discard was estimated and compared with mean kinetic temperature exposure of the devices during the shipment and storage phases and with characteristics of the storage locations using Weibull regression models. We used the time to discard distributions in a Monte Carlo simulation to estimate wastage rates in a hypothetical program setting.

Results:

Time for shipment and transfer to long-term refrigerated storage and mean kinetic temperature during the shipment phase was 8.6 days/10.3°C and 13.4 days/12.1°C, for the first and second simulation studies, respectively. Median (range) time to discard when stored under field conditions (unrefrigerated) was 43 (6 to 59) days and 33 (14 to 50) days, respectively. Mean time to discard was 10.0 days shorter in the second simulation, during which mean kinetic temperature exposure was 3.9°C higher. Simulating a monthly distribution system and assuming typical usage, predicted wastage of product was less than 10%.

Conclusion:

The time to discard of devices was highly sensitive to small changes in temperature exposure. Under field conditions typical in rural Ghana, OIU packages will have a half-life of approximately 30 to 40 days based on the temperature monitor used during the study. Program managers will need to carefully consider variations in both ambient temperature and rate of use to allocate the appropriate supply level that will maximize coverage and minimize stock loss.

Effect on postpartum hemorrhage of prophylactic oxytocin (10 IU) by injection by community health officers in Ghana: a community-based, cluster-randomized trial

BACKGROUND

Oxytocin (10 IU) is the drug of choice for prevention of postpartum hemorrhage (PPH). Its use has generally been restricted to medically trained staff in health facilities. We assessed the effectiveness, safety, and feasibility of PPH prevention using oxytocin injected by peripheral health care providers without midwifery skills at home births.

METHODS AND FINDINGS

This community-based, cluster-randomized trial was conducted in four rural districts in Ghana. We randomly allocated 54 community health officers (stratified on district and catchment area distance to a health facility: ≥10 km versus <10 km) to intervention (one injection of oxytocin [10 IU] one minute after birth) and control (no provision of prophylactic oxytocin) arms. Births attended by a community health officer constituted a cluster. Our primary outcome was PPH, using multiple definitions; (PPH-1) blood loss ≥500 mL; (PPH-2) PPH-1 plus women who received early treatment for PPH; and (PPH-3) PPH-2 plus any other women referred to hospital for postpartum bleeding. Unsafe practice is defined as oxytocin use before delivery of the baby. We enrolled 689 and 897 women, respectively, into oxytocin and control arms of the trial from April 2011 to November 2012. In oxytocin and control arms, respectively, PPH-1 rates were 2.6% versus 5.5% (RR: 0.49; 95% CI: 0.27-0.88); PPH-2 rates were 3.8% versus 10.8% (RR: 0.35; 95% CI: 0.18-0.63), and PPH-3 rates were similar to those of PPH-2. Compared to women in control clusters, those in the intervention clusters lost 45.1 mL (17.7-72.6) less blood. There were no cases of oxytocin use before delivery of the baby and no major adverse events requiring notification of the institutional review boards. Limitations include an unblinded trial and imbalanced numbers of participants, favoring controls.

CONCLUSION

Maternal health care planners can consider adapting this model to extend the use of oxytocin into peripheral settings including, in some contexts, home births.

Impact on postpartum hemorrhage of prophylactic administration of oxytocin 10 IU via Uniject™ by peripheral health care providers at home births: design of a community-based cluster-randomized trial

Background

Hemorrhage is the leading direct cause of maternal death globally. While oxytocin is the drug of choice for postpartum hemorrhage prevention, its use has generally been limited to health facilities. This trial assesses the effectiveness, safety, and feasibility of expanding the use of prophylactic intramuscular oxytocin to peripheral health care providers at home births in four predominantly rural districts in central Ghana.

Methods

This study is designed as a community-based cluster-randomized trial in which Community Health Officers are randomized to provide (or not provide) an injection of oxytocin 10 IU via the Uniject^TM injection system within one minute of delivery of the baby to women who request their presence at home at the onset of labor. The primary aim is to determine if administration of prophylactic oxytocin via Uniject™ by this cadre will reduce the risk of postpartum hemorrhage by 50 % relative to deliveries which do not receive the prophylactic intervention. Postpartum hemorrhage is examined under three sequential definitions: 1) blood loss ≥500 ml (BL); 2) treatment for bleeding (TX) and/or BL; 3) hospital referral for bleeding and/or TX and/or BL. Secondary outcomes address safety and feasibility of the intervention and include adverse maternal and fetal outcomes and logistical concerns regarding assistance at home births and the storage and handling of oxytocin, respectively.

Discussion

Results from this trial will build evidence for the effectiveness of expanding the delivery of this established prophylactic intervention to peripheral settings. Complementary data on safety and logistical issues related to this intervention will assist policymakers in low-income countries in selecting both the best uterotonic and service delivery strategy for postpartum hemorrhage prevention. Results of this trial are expected in mid-2013. The trial is registered at ClinicalTrials.gov: NCT01108289.

'Whether you like it or not people with mental problems are going to go to them': a qualitative exploration into the widespread use of traditional and faith healers in the provision of mental health care in Ghana

Limited research has been conducted to explore the factors that support or obstruct collaboration between traditional healers and public sector mental health services. The first aim of this study was to explore the reasons underpinning the widespread appeal of traditional/faith healers in Ghana. This formed a backdrop for the second objective, to identify what barriers or enabling factors may exist for forming bi-sectoral partnerships. Eighty-one semi-structured interviews and seven focus group discussions were conducted with 120 key stakeholders drawn from five of the ten regions in Ghana. The results were analysed through a framework approach. Respondents indicated many reasons for the appeal of traditional and faith healers, including cultural perceptions of mental disorders, the psychosocial support afforded by such healers, as well as their availability, accessibility and affordability. A number of barriers hindering collaboration, including human rights and safety concerns, scepticism around the effectiveness of 'conventional' treatments, and traditional healer solidarity were identified. Mutual respect and bi-directional conversations surfaced as the key ingredients for successful partnerships. Collaboration is not as easy as commonly assumed, given paradigmatic disjunctures and widespread scepticism between different treatment modalities. Promoting greater understanding, rather than maintaining indifferent distances may lead to more successful co-operation in future.

Local suffering and the global discourse of mental health and human rights: an ethnographic study of responses to mental illness in rural Ghana

BACKGROUND

The Global Movement for Mental Health has brought renewed attention to the neglect of people with mental illness within health policy worldwide. The maltreatment of the mentally ill in many low-income countries is widely reported within psychiatric hospitals, informal healing centres, and family homes. International agencies have called for the development of legislation and policy to address these abuses. However such initiatives exemplify a top-down approach to promoting human rights which historically has had limited impact at the level of those living with mental illness and their families.

METHODS

This research forms part of a longitudinal anthropological study of people with severe mental illness in rural Ghana. Visits were made to over 40 households with a family member with mental illness, as well as churches, shrines, hospitals and clinics. Ethnographic methods included observation, conversation, semi-structured interviews and focus group discussions with people with mental illness, carers, healers, health workers and community members.

RESULTS

Chaining and beating of the mentally ill was found to be commonplace in homes and treatment centres in the communities studied, as well as with-holding of food ('fasting'). However responses to mental illness were embedded within spiritual and moral perspectives and such treatment provoked little sanction at the local level. Families struggled to provide care for severely mentally ill relatives with very little support from formal health services. Psychiatric services were difficult to access, particularly in rural communities, and also seen to have limitations in their effectiveness. Traditional and faith healers remained highly popular despite the routine maltreatment of the mentally ill in their facilities.

CONCLUSION

Efforts to promote the human rights of those with mental illness must engage with the experiences of mental illness within communities affected in order to grasp how these may underpin the use of practices such as mechanical restraint. Interventions which operate at the local level with those living with mental illness within rural communities, as well as family members and healers, may have greater potential to effect change in the treatment of the mentally ill than legislation or investment in services alone.
