Perceptions of HIV transmission and pre-exposure prophylaxis among health care workers and community members in Rwanda

Knowledge and attitude to HIV pre exposure prophylaxis among women in five sub-Saharan African countries: a multilevel model analysis of population-based survey 2021-2022

BACKGROUND

HIV Pre-Exposure Prophylaxis (HIV PrEP) may help reduce the rate of HIV infection among women in sub-Saharan Africa (SSA). This study aimed to assess women's knowledge and attitudes toward PrEP, a crucial component of HIV prevention, using nationwide data. It is the first study of its kind conducted in five SSA countries: Burkina Faso, Ghana, Côte d'Ivoire, Kenya, and Tanzania. The primary objective was to examine women's knowledge and attitudes toward PrEP for the prevention of HIV infection, as well as to explore individual- and community-level factors associated with it.

METHODS

The current study utilized the 2021/22 demographic and health survey datasets from five African nations, namely Burkina Faso, Côte d'Ivoire, Ghana, Kenya, and Tanzania. The analysis was performed using Stata 17. A weighted sample of 77,052 women of reproductive age participated in the survey. Univariate and multivariable multilevel logistic regressions were conducted to assess parameters related to knowledge and attitudes toward PrEP in these countries. In both the univariate regression and the final model, the significance of variables was determined using P values of ≤ 0.2 and < 0.05.

RESULTS

Overall, only about 13.88 (95% CI: 13.64,14.12) of women had knowledge and attitudes toward HIV PrEP. The highest (34.29%) and lowest (5.61%) values were observed for Kenya and Tanzania respectively. Higher rates of knowledge, and attitude toward HIV PrEP among women were independently associated with age 25-34 years old (AOR = 1.52, 95% CI:1.41,1.64), and 35-49 years old (AOR = 1.56, 95% CI:1.43,1.69), primary education level (AOR = 1.79,95% CI:1.65,1.95), and secondary/higher education level (AOR = 2.92, 95% CI: 2.67,3.20), richer (AOR = 1.14, 95% CI:1.02,1.27), and richest (AOR = 1.21, 95% CI:1.06,1.37), employed women (AOR = 1.82, 95% CI:1.65,1.99), had media exposure (AOR = 1.49,95% CI:1.40,1.59),knowledge of modern contraception (AOR = 2.62, 95% CI: 1.94,3.43), had at least one ANC visit (AOR = 1.99, 95% CI:1.47,2.69), gave birth at health institutions (AOR = 1.17, 95% CI: 1.02,1.37), ever had given birth (AOR = 1.53, 95% CI: 1.41,1.66), female household heads (AOR = 1.24, 95% CI:1.17,1.31), rural women (AOR = 0.83, 95% CI: 0.76,0.89). Similarly, women from communities with high ANC coverage (AOR = 1.84, 95% CI: 1.61,2.11), high community mass media exposure (AOR = 1.62, 95% CI: 1.39,1.88), and high community wealth level (AOR = 1.48, 95% CI: 1.30,1.68), and women from the high illiteracy rate community (AOR = 0.71, 95% CI: 0.61,0.82) showed statistically significant associations with the outcome variable in the final model.

CONCLUSIONS

Less than one-seventh of women exhibited knowledge of and positive attitudes toward HIV PrEP. All stakeholders involved in HIV/AIDS prevention and control have recognized the significance of the factors mentioned above. Enhancing maternal health services, such as promoting institutional delivery, contraception, antenatal care (ANC), and women's empowerment, alongside harnessing the power of media and embracing these transformative changes, will contribute to a greater understanding of and more favorable attitudes toward HIV PrEP within the population.

Knowledge, attitudes, and associated factors towards HIV pre-exposure prophylaxis among health care providers

The knowledge and attitudes of health care providers were limited as reviewed in many studies. Attitudes and knowledge about pre-exposure prophylaxis among healthcare providers have not been investigated in Ethiopia even though pre-exposure prophylaxis is a novel healthcare topic. The aim was to assess knowledge, attitudes, and associated factors towards pre-exposure prophylaxis among healthcare providers in Gojjam health facilities, North West Ethiopia, 2022. An institutional-based cross-sectional study was conducted from June 1-30 among 410 healthcare providers in public health facilities in the East Gojjam zone. A simple random sampling technique was used to recruit the required study participants. The statistical program EPI Data version 4.6 was used to enter the data, and statistical packages for Social science version 25 was used for analysis. Variables with a p-value less than 0.25 in the bivariable analysis were included in the multivariable logistic regression analysis. Statistical significance was determined with a p-value less than 0.05. The good knowledge and the favorable attitude of healthcare providers toward HIV pre-exposure prophylaxis were 55.7% (50.6-60.2%) and 60.2% (55.0-65.0%) respectively. male participant (AOR 1.67; 95% CI (1.01-2.55), service year ≥ 10 years (AOR 2.52; 95% CI (1.23-5.17), favorable attitudes (AOR 1.92; 95%CI (1.25-2.95), and providers good sexual behavior (AOR 1.85; 95%CI (1.21-2.82) were significantly associated with the good knowledge, and training (AOR 2.15; 95% CI (1.23-3.76), reading the guideline (AOR 1.66; 95% CI (1.02-2.70), and good knowledge (AOR 1.78; 95% CI (1.16-2.75) was significantly associated with the favorable attitudes. In general, the finding of this study shows that the knowledge and attitudes of healthcare providers were low. Since this is a new initiative their knowledge is lower than their attitudes. Male, service year 10 years, and good provider sexual behavior were factors significantly associated with good knowledge. Training, reading the guidelines, and good knowledge were factors significantly associated with a favorable attitudes. As a result, healthcare facilities intervention programs and strategies better target these factors to improve the knowledge and attitudes of healthcare providers. Preparing training programs to enhance knowledge and attitudes towards PrEP is recommended.

Sociodemographic predictors of beliefs about getting HIV infection by witchcraft or supernatural means: a population-based study of 15335 Senegalese women

Aim

To provide more insights about beliefs of witchcraft and supernatural means as causes of human immunodeficiency virus (HIV) among women in Senegal.

Method

We included eligible women from the demographic and health survey conducted in Senegal during the year 2017.

Results

We included 15335 women, of those 620 (4%) thought that they can get HIV through witchcraft or supernatural means. After the adjustment of all available covariates, old age, receiving primary or secondary education, higher wealth index, more frequency of listening to radio, watching television for less than once a week and reading newspaper or magazine for at least once a week were significantly associated with a reduction in the witchcraft and supernatural means beliefs (p < 0.05). Moreover, rural residence was associated with an increase in the wrong HIV beliefs (p < 0.05).

Conclusion

We demonstrated many predictors of the wrong beliefs about getting HIV infection by witchcraft or supernatural means in the Senegalese women. Policymakers should initiate health educational programs in parallel with increasing the socioeconomic status to limit the HIV transmission. In addition, continuous monitoring of the HIV knowledge in the endemic countries is crucial to decrease HIV burden.

Effect of implementation strategies on pre-exposure prophylaxis persistence among female sex workers in South Africa: an interrupted time series study

BACKGROUND

A disproportionate number of new HIV infections in South Africa are among female sex workers; pre-exposure prophylaxis (PrEP) for HIV prevention is freely available to female sex workers in the country, but unique barriers challenge PrEP persistence. TB HIV Care, a large South African non-profit organisation that provides daily oral PrEP (tenofovir disoproxil fumarate and emtricitabine), has implemented multiple strategies to improve PrEP persistence. We aimed to evaluate the effect of different implementation strategies on PrEP persistence in a large-scale real-world setting.

METHODS

In this interrupted time series study, we estimated level changes in 1-month oral PrEP persistence associated with roll-out of various implementation strategies among female sex workers across nine districts in South Africa. We used routinely collected data from TB HIV Care programme files from June 7, 2016, to April 30, 2021. Poisson regression of 1-month persistence was used to assess the effect of these strategies. In secondary analyses, we tested the association between each of the strategies and 4-month persistence.

FINDINGS

The median 1-month PrEP persistence for female sex workers was 33% (IQR 27-40). SMS support and refill reminders were associated with an 11% relative increase in 1-month persistence (risk ratio [RR] 1·11, 95% CI 1·02-1·26) and clinical mentoring for PrEP providers was associated with a 127% relative increase (RR 2·27, 95% CI 1·94-2·66) among female sex workers. The loyalty rewards programme was negatively associated with 1-month persistence (RR 0·71, 95% CI 0·67-0·83). Although clinical mentoring improved 4-month persistence, SMS support text messages had no significant effect.

INTERPRETATION

Identification and subsequent use of clinical mentoring for PrEP providers and SMS support and refill reminders might improve the usefulness of PrEP overall to prevent new HIV infections among female sex workers. PrEP persistence remains an important issue, and strategies to build on our findings are needed.

Factors Associated With HIV-Related Stigma Among Indonesian Healthcare Workers: A Cross-Sectional Online Survey

BACKGROUND

Despite worldwide advances in HIV care and growing scientific knowledge about HIV, stigma and prejudice continue to hinder people living with HIV/AIDS (PLWHA) from seeking treatment and care. HIV-related stigma among healthcare workers in Indonesia has been investigated and measured in only a few empirical studies.

PURPOSE

This study was developed to identify factors related to holding stigmatizing attitudes toward PLWHA among professional healthcare providers in Indonesia.

METHODS

A cross-sectional survey approach using convenience and snowball sampling techniques was used. Data were collected in February and March 2022. All of the participants were healthcare workers in Indonesia who had completed an online survey that collected demographic data and measured HIV-related stigma, fear of HIV transmission, and HIV-related knowledge. Bivariate analysis and multiple linear regression were used to investigate the association between the independent and dependent variables.

RESULTS

The study enrolled 252 participants, including eight physicians (3.2%), 200 nurses (79.4%), and 44 midwives (17.5%). Over two thirds of the participants (65.1%) had no formal HIV training. Stigmatizing attitudes were associated with lower levels of HIV knowledge ( B = -0.480, p < .01), fear of becoming infected with the HIV virus ( B = 0.354, p < .05), and type of HIV care setting ( B = -2.913, p < .05). Of the three participant categories, physicians had the highest levels of both HIV knowledge and PLWHA-related stigma.

CONCLUSIONS

The findings indicate many healthcare workers in Indonesia receive limited formal training on HIV, have low levels of HIV knowledge, and fear HIV transmission. Therefore, providing comprehensive and up-to-date education about HIV for health workers and proper personal protective equipment should be incorporated into programs aimed at reducing stigmatizing attitudes against patients with HIV among healthcare workers in Indonesia.

Integrating PrEP in maternal and child health clinics in Kenya: analysis of a service availability and readiness assessment (SARA) survey

Background

Risk of HIV acquisition is high during pregnancy and postpartum, and pre-exposure prophylaxis (PrEP) is recommended for peripartum populations. Integrating PrEP into maternal and child health (MCH) clinics is feasible and acceptable. Understanding clinics' service availability and readiness is essential for effective scale up.

Methods

The PrEP in Pregnancy, Accelerating Reach and Efficiency study (PrEPARE; NCT04712994) engaged PrEP-experienced facilities previously linked to a programmatic or research study in Western Kenya to document available services and commodities via a modified service availability and readiness assessment (SARA) survey with 20 PrEP tracer items covering: staffing/guidelines, services/equipment, and medicines/commodities. Facilities' prior study engagement occurred between 2017 and 2019; SARA survey data was collected between April 2020 and June 2021. Descriptive statistics were stratified by prior study engagement. ANOVA tests assessed associations between facility characteristics and gaps. Fisher's tests assessed differences in commodity availability and stockouts.

Results

Of the 55 facilities surveyed, 60% had received PrEP training in the last two years, 95% offered PrEP integrated into MCH, and 64% and 78% had both auditory and visual privacy in PrEP and HIV testing service (HTS) delivery spaces, respectively. Supervision frequency was heterogeneous, but 82% had received a supervision visit within 3 months. Availability of commodities was variable and the most commonly unavailable commodities were PrEP in MCH (71% available) and risk assessment screening tool (RAST) and PrEP cards (60% and 75% available, respectively). The number of service and commodity gaps per facility ranged from zero to eight (median: 3; IQR: 2, 5). The most frequent gaps were: PrEP training and risk assessment cards (40% each), lack of privacy in PrEP (36%) and HIV testing services (31%) spaces, PrEP pills in MCH (29%), and PrEP cards (25%). There were no differences in mean number of gaps by county, previous study engagement, or public vs. private status. Level 4 facilities had fewer gaps (mean 2.2) than level 2, 3, and 5 facilities (mean 5.7, 4.5, and 5.3 respectively; p < 0.001).

Conclusions

PrEP service availability and readiness was generally high across MCH facilities. However, there is a need for increased frequency of provider training and supportive supervision focused on fidelity. To address key commodity stockouts such as PrEP pills, implementation of electronic logistics management information systems may be needed. Targeting these gaps is essential to effectively scale up integrated PrEP delivery, especially among facilities with limited infrastructure.

Motivations for pre-exposure prophylaxis uptake and decline in an HIV-hyperendemic setting: findings from a qualitative implementation study in Lesotho

BACKGROUND

Pre-Exposure Prophylaxis (PrEP) has demonstrated clinical efficacy in preventing HIV infection, yet its uptake remains low. This study, conducted in five PrEP implementing districts in Lesotho, examined factors motivating persons at risk of HIV infection to adopt or reject PrEP when offered freely.

METHODS

In-depth interviews were undertaken with stakeholders directly engaged with PrEP policy (n = 5), program implementation (n = 4), and use (current PrEP users = 55, former PrEP users = 36, and PrEP decliners (n = 6)). Focus group discussions (n = 11, 105 total participants) were conducted with health staff directly providing HIV and PrEP services.

RESULTS

Demand for PrEP was reported highest among those at greatest risk for HIV acquisition: those in serodiscordant relationships and/or engaged in sex work. Culturally sensitive PrEP counseling was described as an opportunity to transfer knowledge, build trust, and address user concerns. Conversely, top-down counseling resulted in PrEP distrust and confusion about HIV status. Key motivations for PrEP uptake revolved around sustaining core social relationships, desire for safer conception, and caring for ailing relatives. The decline of PrEP initiation was driven by a combination of individual-level factors (risk perception, perceived side effects, disbelief of the drug's efficacy and PrEP's daily pill regimen), societal factors (lack of social support and HIV-related stigma), and structural factors related to PrEP access.

CONCLUSIONS

Our findings suggest strategies for effective national PrEP rollout and implementation include: (1) demand creation campaigns which highlight positive aspects of PrEP, while simultaneously addressing apprehensions for uptake; (2) strengthening health provider counseling capacity; and (3) addressing societal and structural HIV-related stigma.

Feasibility and acceptability of peer-delivered HIV self-testing and PrEP for young women in Kampala, Uganda

BACKGROUND

Adolescent girls and young women (AGYW) account for 29% of new HIV infections in Uganda despite representing just 10% of the population. Peer support improves AGYW linkage to HIV care and medication adherence. We evaluated the feasibility and acceptability of peer delivered HIV self-tests (HIVST) and oral pre-exposure prophylaxis (PrEP) to young women in Uganda.

METHODS

Between March and September 2021, we conducted a pilot study of 30 randomly selected young women, aged 18-24 years, who had received oral PrEP for at least three months, but had suboptimal adherence as measured by urine tenofovir testing (< 1500 ng/ml). Participants were offered daily oral PrEP and attended clinic visits three and six months after enrollment. Between clinic visits, participants were visited monthly by trained peers who delivered HIVST and PrEP. Feasibility and acceptability of peer-delivered PrEP and HIVST (intervention) were measured by comparing actual versus planned intervention delivery and product use. We conducted two focus groups with young women, and five in-depth interviews with peers and health workers to explore their experiences with intervention delivery. Qualitative data were analyzed using thematic analysis.

RESULTS

At baseline, all 30 enrolled young women (median age 20 years) accepted peer-delivered PrEP and HIVST. Peer delivery visit completion was 97% (29/30) and 93% (28/30) at three and six months, respectively. The proportion of participants with detectable tenofovir in urine was 93% (27/29) and 57% (16/28) at months three and six, respectively. Four broad themes emerged from the qualitative data: (1) Positive experiences of peer delivered HIVST and PrEP; (2) The motivating effect of peer support; (3) Perceptions of female controlled HIVST and PrEP; and (4) Multi-level barriers to HIVST and PrEP use. Overall, peer delivery motivated young women to use HIVST and PrEP and encouraged persistence on PrEP by providing non-judgmental client-friendly services and adherence support.

CONCLUSION

Peer delivery of HIVST and oral PrEP was feasible and acceptable to this sample of young women with suboptimal PrEP adherence in Uganda. Future larger controlled studies should evaluate its effectiveness among African AGWY.

Longitudinal patterns of initiation, persistence, and cycling on preexposure prophylaxis among female sex workers and adolescent girls and young women in South Africa

OBJECTIVE

Female sex workers (FSW) and adolescent girls and young women (AGYW) face a disproportionately high risk of HIV in South Africa. Oral preexposure prophylaxis (PrEP) can avert new infections, but its effectiveness is linked to consistent use. Early discontinuation of PrEP in this population is high, but less is known about longitudinal patterns of PrEP use, including patterns of re-initiation and cycling.

DESIGN

Longitudinal descriptive analysis of routine program data.

METHODS

Between 2016 and 2021, 40 681 FSW and AGYW initiated PrEP at TB HIV Care, the largest PrEP provider to this population in South Africa and were included. Using survival analyses and group-based trajectory modeling, we described patterns of initiation, discontinuation, re-initiation, and cycling.

RESULTS

Total initiations increased over the life of the program for both FSW and AGYW. About 40% of FSW [0.41, 95% confidence interval (CI) [0.40-0.42]] and AGYW (0.38, 95% CI [0.37-0.38]) remained on PrEP at one month. FSW were more likely to restart PrEP, however <10% restarted PrEP within a year of initiation. Three latent trajectory groups of PrEP use were identified for FSW (low use, early cycling, and ongoing cycling) and two for AGYW (low use and ongoing cycling). Persistence was negatively associated with initiation among AGYW, but there was no clear relationship among FSW. Those initiating later in the program and older women had a reduced risk of discontinuation.

CONCLUSIONS

Persistence on PrEP was low, but cycling on and off PrEP was common, with early missed visits and inconsistent, but ongoing use. A push to increase PrEP initiations needs to factor in readiness and persistence support, to achieve public health impact.

Multi-level Factors Driving Pre-exposure Prophylaxis Non-initiation Among Young Women at High Risk for HIV in Kenya

Few studies have focused on understanding pre-exposure prophylaxis (PrEP) non-initiation among young, high-risk women in sub-Saharan Africa. This study aimed to qualitatively explore why young women in Kenya at high-risk for HIV chose not to enroll in a PrEP adherence trial. We performed 40 semi-structured interviews with young high-risk women assessing concerns about PrEP and/or study participation. We also assessed community-level factors influencing decision-making around PrEP through 10 focus groups involving peers, young men, caregivers, and community leaders. Our qualitative data reflect the complexity of navigating barriers preventing PrEP initiation in settings where taking PrEP may be perceived as immoral behavior. Framed within the context of risk perception, the decision to start PrEP may run counter to the potential risk of losing support from one's community. Our findings suggest that approaches addressing social norms, while de-medicalizing HIV prevention services, are needed to further increase PrEP uptake among young Kenyan women.

Providers' Attitudes and Experiences with Pre-Exposure Prophylaxis Implementation in a Population-Based Study in Kenya and Uganda

Pre-exposure prophylaxis (PrEP) implementation is underway across sub-Saharan Africa. However, little is known about health care providers' experiences with PrEP provision in generalized epidemic settings, particularly outside of selected risk groups. In this study (NCT01864603), universal access to PrEP was offered to adolescents and adults at elevated risk during population-level HIV testing in rural Kenya and Uganda. Providers received training on PrEP prescribing and support from local senior clinicians. We conducted in-depth interviews with providers (n = 19) in four communities in Kenya and Uganda to explore the attitudes and experiences with implementation. Transcripts were coded and analyzed using interpretivist methods. Providers had heterogenous attitudes toward PrEP in its early implementation: some expressed enthusiasm, while others feared being blamed for "failures" (HIV seroconversions) if participants were nonadherent, or that offering PrEP would increase "immorality." Providers supported PrEP usage among HIV-serodifferent couples, whose mutual support for daily pill-taking facilitated harmony and protection from HIV. Providers reported challenges with counseling on "seasons of risk," and safely stopping and restarting PrEP. They felt uptake was hampered for women by difficulties negotiating with partners, and for youth by parental consent requirements. They believed PrEP continuation was hindered by transportation costs, stigma, pill burden, and side effects, and was facilitated by counseling, proactive management of side effects, and home/community-based provision. Providers are critical "implementation actors" in interventions to promote adoption of new technologies such as PrEP. Dedicated training and ongoing support for providers may facilitate successful scale-up.

Potential Role of Conversational Agents in Encouraging PrEP Uptake

Approximately 1.2 million people are living with HIV, with many of them unaware of their infection. Pre-exposure prophylaxis (PrEP) is available to minimize transmission among those at high risk for infection, including men who have sex with men, people who inject drugs, and female sex workers. Despite its availability, there is low usage of PrEP. To address this problem, various digital tools have been examined in HIV research. Among those, conversational agents are still underused and their capacity warrants examination to reach at-risk populations. In this paper, we discuss the potential of conversational agents in increasing uptake of PrEP by addressing barriers experienced among those at high risk for infection.

Introducing the Dapivirine Vaginal Ring in Sub-Saharan Africa: What Can We Learn from Oral PrEP?

PURPOSE OF REVIEW

Clinical trials have found that the dapivirine vaginal ring (DVR) is safe to use and effective at reducing women's risk of acquiring HIV infection. As countries prepare for the introduction of this novel long-acting, woman-controlled prevention method, an examination of key learnings from oral pre-exposure prophylaxis (PrEP) delivery will help programs leverage successful innovations and approaches to support DVR scale-up and expand the method mix for HIV prevention.

RECENT FINDINGS

Intensive efforts over the past 5 years have yielded lessons on how to facilitate access to oral PrEP; expand service delivery for PrEP; address the knowledge, attitudes, and skills providers need to support PrEP initiation and effective use; develop messaging that builds community and partner support and combats stigma; and understand the cyclical nature of PrEP use. Evidence from oral PrEP introduction and scale-up can help inform and expedite DVR introduction.

Health care providers' attitudes toward and experiences delivering oral PrEP to adolescent girls and young women in Kenya, South Africa, and Zimbabwe

Background

In Kenya, South Africa, and Zimbabwe, oral pre-exposure prophylaxis (PrEP) is recommended for adolescent girls and young women (AGYW) at high risk of HIV. Health providers play a critical role in the uptake and effective use of sexual and reproductive health services; however, few published studies have explored providers’ attitudes toward and experiences delivering PrEP to AGYW.

Methods

We conducted a cross-sectional qualitative study, interviewing 113 providers at 36 public, private, and nongovernmental health facilities in Kenya, South Africa, and Zimbabwe that were offering PrEP during the research period or were likely to offer PrEP in the future. Data were coded in NVivo 11, and an applied thematic analysis was conducted.

Results

Most providers preferred that adolescent girls wait until age 18 to have sex but acknowledged that many girls younger than 18 could benefit from oral PrEP. Their primary concern was whether adolescent girls would be able to take PrEP daily, especially if they do not tell their parents or partners they are using it. Providers reported that it was more challenging to deliver PrEP and other HIV services to girls younger than 18. Those with experience providing PrEP pointed to stigma and lack of PrEP awareness in communities as two primary barriers to PrEP uptake and use.

Conclusions

Providers were generally accepting of oral PrEP as an HIV prevention option for AGYW; however, many had negative attitudes about adolescent girls being sexually active and concerns about whether they could take PrEP daily. Results were used to update national PrEP training materials to address negative provider attitudes about PrEP use by AGYW.

Low costs and opportunities for efficiency: a cost analysis of the first year of programmatic PrEP delivery in Kenya's public sector

Background

In 2017, the Kenyan Ministry of Health integrated provision of pre-exposure prophylaxis (PrEP) into public HIV-1 care clinics as a key component of the national HIV-1 prevention strategy. Estimates of the cost of PrEP provision are needed to inform the affordability and cost-effectiveness of PrEP in Kenya.

Methods

We conducted activity-based micro-costing from the payer perspective to estimate both the financial and economic costs of all resources and activities required to provide PrEP in Kenya’s public sector. We estimated total and unit costs in 2019 United States dollars from a combination of project expense reports, Ministry of Health training reports, clinic staff interviews, time-and-motion observations, and routinely collected data from PrEP recipient files from 25 high-volume HIV-1 care clinics.

Results

In the first year of programmatic PrEP delivery in 25 HIV-1 care clinics, 2,567 persons initiated PrEP and accrued 8,847 total months of PrEP coverage, accounting for 2 % of total outpatient clinic visits. The total financial cost to the Ministry of Health was $91,175, translating to an average of $10.31 per person per month. The majority (69 %) of financial costs were attributable to PrEP medication, followed by administrative supplies (17 %) and training (9 %). Economic costs were higher ($188,584 total; $21.32 per person per month) due to the inclusion of the opportunity cost of staff time re-allocated to provide PrEP and a proportional fraction of facility overhead. The vast majority (88 %) of the annual $80,811 economic cost of personnel time was incurred during activities to recruit new clients (e.g., discussion of PrEP within HIV-1 testing and counselling services), while the remaining 12 % was for activities related to both initiation and maintenance of PrEP provision (e.g., client consultations, technical advising, support groups).

Conclusions

Integration of PrEP provision into existing public health HIV-1 care service delivery platforms resulted in minimal additional staff burden and low incremental costs. Efforts to improve the efficiency of PrEP provision should focus on reductions in the cost of PrEP medication and extra-clinic demand creation and community sensitization to reduce personnel time dedicated to recruitment-related activities.

"We've Got Our Own Beliefs, Attitudes, Myths": A Mixed Methods Assessment of Rural South African Health Care Workers' Knowledge of and Attitudes Towards PrEP Implementation

South Africa maintains the world's largest HIV prevalence, accounting for 20.4% of people living with HIV internationally. HIV Pre-exposure prophylaxis (PrEP) has demonstrated efficacy; however, there is limited data on PrEP implementation in South Africa, particularly in rural areas. Using grounded theory analysis of semi-structured interviews and exploratory factor analyses of structured surveys, this mixed methods study examines healthcare workers' (HCWs)' beliefs about their patients and the likelihood of PrEP uptake in their communities. The disproportionate burden of HIV among Black South Africans is linked to the legacy of apartheid and resulting disparities in wealth and employment. HCWs in our study emphasized the importance of addressing these structural barriers, including increased travel burden among men in the community looking for work, poor transportation infrastructure, and limited numbers of highly skilled clinical staff in their rural community. HCWs also espoused a vision of PrEP that prioritizes women due to perceived constraints on their sexual agency, and that minimizes the impact of HIV-related stigma on PrEP implementation. However, HCWs' additional concerns for risk compensation may reflect dominant social mores around sexual behavior. In recognition of HCWs' role as both informants and community members, implementation scientists should invite local HCWs to partner as early as the priority-setting stage for PrEP interventions. Inviting leadership from local HCWs may increase the likelihood of delivery plans that account for unique local context and structural barriers researchers may otherwise struggle to uncover.

Health system adaptations and considerations to facilitate optimal oral pre-exposure prophylaxis scale-up in sub-Saharan Africa

Following WHO's 2015 recommendation, countries in sub-Saharan Africa have progressively scaled up oral pre-exposure prophylaxis (PrEP) as part of combination HIV prevention. PrEP has potential to significantly reduce new HIV infections in sub-Saharan Africa if it is widely available, accessible, and effectively used. Initial scale-up efforts have generated progress, drawing lessons from existing HIV interventions, such as antiretroviral therapy and biomedical prevention. However, beset by unprepared health systems, scale-up has been slow, resulting in suboptimal coverage among priority groups at higher risk of HIV acqusition. Using the WHO health system building blocks framework, this Review synthesises literature on essential considerations for PrEP scale-up in sub-Saharan Africa, highlighting the importance of health system adaptability and responsiveness.

Awareness of and willingness to use HIV pre-exposure prophylaxis among community residents

INTRODUCTION

Human Immunodeficiency Virus (HIV) Pre-exposure prophylaxis (PrEP) helps to decrease HIV acquisition and transmission rates. The purpose of this study was to assess awareness of HIV PrEP and willingness to use it, if available, among individuals residing in Buea, Cameroon.

METHODS

Residents in different communities throughout Buea, Cameroon participated in the study through survey completion with their responses assessed by age, marital status, highest level of education completed, profession, and health area (urban or rural).

RESULTS

421 participants completed the survey with the majority being 20-29 years of age, single, having secondary or tertiary education, residing in rural Cameroonian areas. Eighty percent of respondents had not previously heard of HIV PrEP. Ninety-five percent of the study sample expressed willingness to use HIV PrEP, if available. Participants ages 40 years old and above were less aware of HIV PrEP than those 39 years old and younger. Primary education, serving in the role of a nurse, doctor, or scientist, along with hospital affiliations were characteristics closely associated with HIV PrEP awareness. Participants younger than 20 years old were less likely to report willingness to use HIV PrEP whereas married participants found HIV PrEP to be a more favorable option.

CONCLUSIONS

Awareness of HIV PrEP was minimal with healthcare personnel having more familiarity. Willingness to use HIV PrEP decreased by age but higher among married participants. Further promotion of HIV PrEP and facilitating its accessibility can lead to less transmissions of HIV worldwide.

PrEP rollout in Africa: status and opportunity

Following recommendations by the World Health Organization in 2015, and key clinical trials, countries in sub-Saharan Africa, the region with the highest burden of human immunodeficiency virus (HIV), developed policies that incorporate pre-exposure prophylaxis (PrEP) into national HIV-prevention strategies. By the end of 2019, more than one third of people receiving PrEP globally were in Africa. Crucial understandings gained from early rollout among at-risk populations, such as HIV-serodiscordant couples, adolescent girls and young women, female sex workers, and men who have sex with men, include the importance of strategies for maintaining persistent adherence to PrEP and novel approaches to making PrEP services accessible, simplified and efficient. This Perspective will discuss the current status of these programs and how to further widen their implementation.
