Reaching Adolescent Girls and Young Women With HIV Self-Testing and Contraception at Girl-Friendly Drug Shops: A Randomized Trial in Tanzania.

PURPOSE: We hypothesized that an intervention designed to create girl-friendly drug shops would increase access to sexual and reproductive health products and services among adolescent girls and young women (AGYW) (ages 15-24 years) in Tanzania. METHODS: We conducted a four-month randomized trial at 20 drug shops in Shinyanga, Tanzania from August-December 2019 to determine if the Malkia Klabu ("Queen Club") intervention increased AGYW patronage and the provision of HIV self-testing (HIVST), contraception, and health facility referrals to AGYW (primary outcomes). Drug shops were randomized 1:1 to the intervention or comparison arm. All shops were provided with OraQuick HIVST kits to give to AGYW for free. Intervention shops implemented Malkia Klabu, a loyalty program for AGYW created using human-centered design through which AGYW could also access free contraception. We compared outcomes in intention-to-treat analyses using shop observations and shopkeeper records. RESULTS: By endline, shops implementing Malkia Klabu had higher AGYW patronage than comparison shops (rate ratio: 4.4; 95% confidence interval: 2.0, 9.8). Intervention shops distributed more HIVST kits (median per shop: 130.5 vs. 58.5, P = .02) and contraceptives (325.5 vs. 7.0, P < .01) to AGYW and provided more referrals for HIV, family planning, or pregnancy services combined (3.5 vs. 0.5, P = .02) than comparison shops. DISCUSSION: The Malkia Klabu intervention increased AGYW patronage and the provision of HIVST kits, contraception, and referrals to AGYW at drug shops, despite HIVST kits being freely available at all participating shops. Enhancing drug shops with girl-friendly services may be an effective strategy to reach AGYW with sexual and reproductive health services.

Financial incentives to improve re-engagement in HIV care: results from a randomized pilot study.

OBJECTIVE: Determine the feasibility, acceptability, and preliminary effectiveness of financial incentives to motivate re-engagement in HIV care in Shinyanga, Tanzania. METHODS: Out-of-care people living with HIV (PLHIV) were identified from medical records in four clinics and home-based care providers (HBCs) from April 13, 2018 to March 3, 2020. Shinyanga Region residents, ≥18 years, who were disengaged from care were randomized 1:1 to a financial incentive (∼$10 USD) or the standard of care (SOC), stratified by site, and followed for 180 days. Primary outcomes were feasibility (located PLHIV who agreed to discuss the study), acceptability (enrollment among eligibles), and re-engagement in care (clinic visit within 90 days). RESULTS: HBCs located 469/1,309 (35.8%) out-of-care PLHIV. Of these, 215 (45.8%) were preliminarily determined to be disengaged from care, 201 (93.5%) agreed to discuss the study, and 157 eligible (100%) enrolled. Within 90 days, 71 (85.5%) PLHIV in the incentive arm re-engaged in care vs. 58 (78.4%) in the SOC (Adjusted Risk Difference [ARD] = 0.08, 95% CI: -0.03, 0.19, p = 0.09). A higher proportion of incentivized PLHIV completed an additional (unincentivized) visit between 90-180 days (79.5% vs. 71.6%, ARD = 0.10, 95% CI: -0.03, 0.24, p = 0.13) and remained in care at 180 days (57.8% vs. 51.4%, ARD = 0.07, 95% CI: -0.09, 0.22, p = 0.40). CONCLUSIONS: Short-term financial incentives are feasible, acceptable, and have the potential to encourage re-engagement in care, warranting further study of this approach.

Profiling of antimicrobial dispensing practices in accredited drug dispensing outlets in Tanzania: a mixed-method cross-sectional study focusing on pediatric patients.

BACKGROUND: The emergency of antimicrobial resistance due to irrational antimicrobial use has put public health under threat. Accredited Drug Dispensing Outlets (ADDOs) play an important role in enhancing availability and accessibility of antimicrobials, however, there is a scarcity of studies assessing antimicrobial dispensing practices in these outlets, focusing on children in Tanzania. OBJECTIVE: This study was conducted to assess the antimicrobial dispensing practices among ADDO dispensers and explore the factors influencing the use of antimicrobials for children in Tanzania. METHODS: A community-based cross-sectional study utilizing both qualitative (interviews) and quantitative (simulated clients) methods was conducted between June and September 2020 in seven zones and 14 regions in Tanzania. RESULTS: The study found inappropriate dispensing and use of antimicrobials for children, influenced by multiple factors such as patient's and dispenser's knowledge and attitude, financial constraints, and product-related factors. Only 8% (62/773) of dispensers asked for prescriptions, while the majority (90%) were willing to dispense without prescriptions. Most dispensers, 83% (426/513), supplied incomplete doses of antimicrobials and only 60.5% (345/570) of the dispensers gave proper instructions for antimicrobial use to clients. Over 75% of ADDO dispensers displayed poor practice in taking patient history. CONCLUSION: ADDO dispensers demonstrated poor practices in dispensing and promoting rational antimicrobial use for children. Training, support, and regulatory interventions are required to improve antimicrobial dispensing practices in community drug outlets.

Implementation of antibiotic stewardship programmes in paediatric patients in regional referral hospitals in Tanzania: experience from prescribers and dispensers.

Background: In 2017, Tanzania launched the National Action Plan for Antimicrobial Resistance (NAPAR), 2017-2022 and implementation of antibiotic stewardship programmes (ASPs) was one of the agendas. Since the launch of the National Action Plan, no study has been done to assess its implementation. Objectives: To explore the experiences of prescribers and dispensers on implementing ASPs among paediatric patients attending Regional Referral Hospitals (RRHs) in Tanzania. Methods: An exploratory qualitative study was conducted among key informants, in 14 RRHs in Tanzania between July and August 2020. A total of 28 key informants, 14 dispensers in charge of pharmacies and 14 medical doctors in charge of paediatric departments (prescribers), were interviewed. A hybrid thematic analysis was conducted on the gathered information. Results: Most of the study participants were not conversant with the term 'antibiotic stewardship'. Some had heard about the programmes but were not aware of the activities involved in the programme. Those who were knowledgeable on ASPs mentioned the lack of existence of such programmes in their settings. They further added that absence or limited knowledge of the stewardship concepts may have influenced the current poor practices. Barriers to the implementation of ASPs mentioned were lack of laboratory facilities to support culture and susceptibility tests, lack of materials and reagents, management pressure to prevent loss or to generate income, patients' influence and limited training opportunities. Conclusions: Despite launching the NAPAR in 2017, we found limited implementation of ASPs in the management of paediatric patients. This study highlighted some barriers and identified possible intervention points.

Drivers of irrational use of antibiotics among children: a mixed-method study among prescribers and dispensers in Tanzania.

BACKGROUND: Misuse of antibiotics has been associated with poor knowledge, attitude and practice (KAP). Therefore, this study aimed to assess if KAP of prescribers and dispensers could drive irrational use of antibiotics among children in Tanzania. METHODS: A convergent parallel mixed-methods study design that employed quantitative and qualitative approaches was conducted in 14 regional referral hospitals (RRHs). A total of 108 participants, prescribers [54] and dispensers [54] working with the pediatric population in the respective regions participated in a quantitative survey, by filling the standard questionnaire while 28 key informant interviews were conducted with in-charges of units from the pharmacy and pediatric departments. Two key informants (prescriber and dispenser) were selected from each RRH. RESULTS: Overall, among prescribers and dispensers, there was adequate knowledge; 81.5% and 79.6%, p = 0.53, those with positive attitudes were 31.5% and 81.5%, p < 0.001 and poor practices were among 70.4% and 48% p = 0.0312 respectively. Among prescribers, 14.8% agreed and strongly agreed that prescribing antibiotics that a patient did not need does not contribute to resistance. Moreover 19% disagreed to prescribe antibiotics according to local guidelines. Among dispensers, a-quarter of the dispensers thought individual efforts to implement antibiotic stewardship would not make a difference, 17% agreed and strongly agreed that antibiotics can treat viral infection and 7% agreed and strongly agreed antibiotics can be stopped upon resolution of symptoms. From qualitative interviews, both participants displayed an adequate understanding of multi-contributors of antibiotic resistance (AR) including polypharmacy, community self-medication, among others. Regardless, both professions declared to prescribed and dispensed antibiotics according to the antibiotics available in stock at the facility. Furthermore, prescribers perceived laboratory investigation took a long time, hence wasting their time. On the other hand, Dispensers reported not to provide adequate instruction to the patients, after dispensing antibiotics. CONCLUSIONS: Both prescribers and dispensers had adequate knowledge, few prescribers had positive attitudes and the majority had poor practices. Few dispensers had poor attitude and practice. These findings highlight the need to provide adequate training on antimicrobial stewardship and enforce regulation that foster appropriate medical practice.

Compliance to infection prevention and control interventions for slowing down COVID-19 in early phase of disease transmission in Dar es Salaam, Tanzania.

Introduction: on 16th March 2020, Tanzania announced its first COVID-19 case. The country had already developed a 72-hour response plan and had enacted three compulsory infection prevention and control interventions. Here, we describe public compliance to Infection Prevention and Control (IPC) public health measures in Dar es Salaam during the early COVID-19 response and testing of the feasibility of an observational method. Methods: a cross sectional study was conducted between April and May 2020 in Dar es Salaam City. At that time, Dar es Salaam was the epi centre of the epidemic. Respondents were randomly selected from defined population strata (high, medium and low). Data were collected using a structured questionnaire and through observations. Results: a total of 390 subjects were interviewed, response rate was 388 (99.5%). Mean age of the respondents was 34.8 years and 168 (43.1%) had primary level education. Out of the 388 respondents, 384 (98.9%) reported to have heard about COVID-19 public health and social measures, 90.0% had heard from the television and 84.6% from the radio. Covering coughs and sneezes using a handkerchief was the most common behaviour observed among 320 (82.5%) respondents; followed by hand washing hygiene practice, 312 (80.4%) and wearing face masks, 240 (61.9%). Approximately 215 (55.4%) adhered to physical distancing guidance. Age and gender were associated with compliance to IPC measures (both, p<0.05). Conclusion: compliance to public health measures during the early phase of COVID-19 pandemic in this urban setting was encouraging. As the pandemic continues, it is critical to ensure compliance is sustained and capitalize on risk communication via television and radio.

Determinants of misuse of antibiotics among parents of children attending clinics in regional referral hospitals in Tanzania.

Parents are the important implementers on appropriate/inappropriate use of antibiotics, especially in the pediatric population. Limited studies have associated poor knowledge, attitude, and practice (KAP) among parents with antibiotics misuse. Therefore, this study was conducted to determine the parents' KAP and factors associated with inappropriate use of antibiotics among Tanzanian children. A hospital-based cross-sectional study was conducted in 14 regional referral hospitals (RRHs) in Tanzania between June and September 2020. KAP was estimated using a Likert scale, whereas KAP factors were determined using logistic regression models. A total of 2802 parents were enrolled in the study. The median age (interquartile range) of parents was 30.0 (25-36) years where 82.4% (n = 2305) were female parents. The majority of the parents had primary education, 56.1% (n = 1567). Of 2802 parents, only 10.9% (n = 298) had good knowledge about antibiotics, 16.4% (n = 455) had positive attitude whereas 82.0% (n = 2275) had poor practice on the appropriate use of antibiotics. Parents' education level, i.e., having a university degree (aOR: 3.27 95% CI 1.62-6.63, p = 0.001), good knowledge (aOR: 1.70, 95% CI 1.19-2.23, p = 0.003) and positive attitudes (aOR: 5.56, 95% CI 4.09-7.56, p < 0.001) were significantly associated with the appropriate use of antibiotics in children. Most parents had poor knowledge, negative attitude, and poor practice towards antibiotics use in children. Parents' education level, employment status, knowledge on antibiotic use, and good attitude contributed to the appropriate use of antibiotics in children attending clinics at RRHs.

A growing disadvantage of being born in an urban area? Analysing urban-rural disparities in neonatal mortality in 21 African countries with a focus on Tanzania.

INTRODUCTION: Neonatal mortality rate (NMR) has been declining in sub-Saharan African (SSA) countries, where historically rural areas had higher NMR compared with urban. The 2015-2016 Demographic and Health Survey (DHS) in Tanzania showed an exacerbation of an existing pattern with significantly higher NMR in urban areas. The objective of this study is to understand this disparity in SSA countries and examine the specific factors potentially underlying this association in Tanzania. METHODS: We assessed urban-rural NMR disparities among 21 SSA countries with four or more DHS, at least one of which was before 2000, using the DHS StatCompiler. For Tanzania DHS 2015-2016, descriptive statistics were carried out disaggregated by urban and rural areas, followed by bivariate and multivariable logistic regression modelling the association between urban/rural residence and neonatal mortality, adjusting for other risk factors. RESULTS: Among 21 countries analysed, Tanzania was the only SSA country where urban NMR (38 per 1000 live births) was significantly higher than rural (20 per 1,000), with largest difference during first week of life. We analysed NMR on the 2015-2016 Tanzania DHS, including live births to 9736 women aged between 15 and 49 years. Several factors were significantly associated with higher NMR, including multiplicity of pregnancy, being the first child, higher maternal education, and male child sex. However, their inclusion did not attenuate the effect of urban-rural differences in NMR. In multivariable models, urban residence remained associated with double the odds of neonatal mortality compared with rural. CONCLUSION: There is an urgent need to understand the role of quality of facility-based care, including role of infections, and health-seeking behaviour in case of neonatal illness at home. However, additional factors might also be implicated and higher NMR within urban areas of Tanzania may signal a shift in the pattern of neonatal mortality across several other SSA countries.

Durability of effects from short-term economic incentives for clinic attendance among HIV positive adults in Tanzania: long-term follow-up of a randomised controlled trial.

INTRODUCTION: Conditional economic incentives are shown to promote medication adherence across a range of health conditions and settings; however, any long-term harms or benefits from these time-limited interventions remain largely unevaluated. We assessed 2-3 years outcomes from a 6-month incentive programme in Tanzania that originally improved short-term retention in HIV care and medication possession. METHODS: We traced former participants in a 2013-2016 trial, which randomised 800 food-insecure adults starting HIV treatment at three clinics to receive either usual care (control) or up to 6 months of cash or food transfers (~US$11/month) contingent on timely attendance at monthly clinic appointments. The primary intention-to-treat analysis estimated 24-month and 36-month marginal risk differences (RD) between incentive and control groups for retention in care and all-cause mortality, using multiple imputation for a minority of missing outcomes. We also estimated mortality HRs from time-stratified Cox regression. RESULTS: From 3 March 2018 to 19 September 2019, we determined 36-month retention and mortality statuses for 737 (92%) and 700 (88%) participants, respectively. Overall, approximately 660 (83%) participants were in care at 36 months while 43 (5%) had died. There were no differences between groups in retention at 24 months (86.5% intervention vs 84.4% control, RD 2.1, 95% CI -5.2 to 9.3) or 36 months (83.3% vs 77.8%, RD 5.6, -2.7 to 13.8), nor in mortality at either time point. The intervention group had a lower rate of death during the first 18 months (HR 0.27, 95% CI 0.10 to 0.74); mortality was similar thereafter (HR 1.13, 95% CI 0.33 to 3.79). CONCLUSION: These findings confirm that incentives are a safe and effective tool to promote short-term adherence and potentially avert early deaths at the critical time of HIV treatment initiation. Complementary strategies are recommended to sustain lifelong retention in HIV care. TRIAL REGISTRATION NUMBER: NCT01957917.

Designing drug shops for young women in Tanzania: applying human-centred design to facilitate access to HIV self-testing and contraception.

Adolescent and young adult women in sub-Saharan Africa experience barriers to sexual and reproductive health (SRH) services that elevate their risk of human immunodeficiency virus (HIV) acquisition and unintended pregnancy. Community drug shops may be effective distribution points to connect young women with SRH products. Thus, we used human-centred design (HCD) to create drug shops where young women could access HIV self-testing and contraception in Shinyanga, Tanzania. Enhancing the HCD process with behavioural science, we collected diverse data (i.e. 18 in-depth interviews, 9 'shadowing' interviews, 6 shop observations, 6 focus groups) to understand the latent needs and motivations of young women and drug shopkeepers, brainstormed creative solutions and iteratively refined and tested solutions for acceptability, feasibility and cultural fit. We found a widespread moral imperative to control young women's behaviour via misinformation about SRH, community gossip and financial control. Young women often engaged in mundane shopping at the behest of others. At drug shops, few SRH products were deemed appropriate for unmarried women, and many reactively sought SRH products only after engaging in higher risk behaviours. In response to these insights, we designed the 'Malkia Klabu' ('Queen Club') loyalty programme through which young women could earn mystery prizes by shopping at drug shops and discreetly request free SRH products, including HIV self-test kits, by pointing at symbols on loyalty cards. Our HCD approach increases the likelihood that the intervention will address the specific needs and preferences of both drug shopkeepers and young women. We will evaluate its effectiveness in a randomized trial.

Sales and pricing decisions for HIV self-test kits among local drug shops in Tanzania: a prospective cohort study.

BACKGROUND: Public health initiatives must look for ways to cost-effectively scale critical interventions to achieve high coverage. Private sector distribution channels, can potentially distribute preventive healthcare products to hard-to-reach populations, decongest public healthcare systems, and increase the sustainability of programs by getting customers to share costs. However, little is known about how sellers set prices for new products. By introducing a new product, HIV self-test kits, to local drug shops, we observed whether shops experimented with pricing, charged different buyers different prices, and whether prices converged within the local market over our study period. METHODS: From August to December 2019, we provided free HIV self-test kits, a new product, to 26 drug shops in Shinyanga, Tanzania to sell to the local community. We measured sales volume, price, customer age and sex using shop records. Using a multiple linear regression model, we conducted F-tests to determine whether shop, age, sex, and time (week) respectively were associated with price. We measured willingness-to-pay to restock test kits at the end of the study. RESULTS: 514 test kits were sold over 18 weeks; 69% of buyers were male, 40% were aged 25-34 and 32% aged 35-44. Purchase prices ranged from 1000 to 6000 Tsh (median 3000 Tsh; ~$1.30 USD). Within shops, prices were 11.3% higher for 25-34 and 12.7% higher for 45+ year olds relative to 15-19-year olds (p = 0.029) and 13.5% lower for men (p = 0.023) on average. Although prices varied between shops, prices varied little within shops over time, and did not converge over the study period or cluster geospatially. Mean maximum willingness-to-pay to restock was 2000 Tsh per kit. CONCLUSIONS: Shopkeepers charged buyers different prices depending on buyers' age and sex. There was limited variation in prices within shops over time and low demand among shopkeepers to restock at the end of the study. Given the subsidized global wholesale price ($2 USD or ~ 4600 Tsh), further demand creation and/or cost-reduction is required before HIV self-test kits can become commercially viable in drug shops in this setting. Careful consideration is needed to align the motivations of retailers with public health priorities while meeting their private for-profit needs.

HIV prevention at drug shops: awareness and attitudes among shop dispensers and young women about oral pre-exposure prophylaxis and the dapivirine ring in Shinyanga, Tanzania.

BACKGROUND: HIV risk remains high among adolescent girls and young women (AGYW, ages 15-24) in Tanzania. Many AGYW experience stigma and provider bias at health facilities, deterring their use of HIV prevention services. Privately-owned drug shops, ubiquitous in many communities, may be an effective and accessible channel to deliver HIV prevention products to AGYW, including oral pre-exposure prophylaxis (PrEP) and the dapivirine vaginal ring. METHODS: In July-August 2019, we enrolled 26 drug shops in Shinyanga, Tanzania in an ongoing study to create "girl-friendly" drug shops where AGYW can access HIV self-testing and contraception. At baseline, all shop dispensers were given basic information about oral PrEP and the dapivirine ring and were asked about their interest in stocking each. During the next 3-5 months, we surveyed AGYW (n = 56) customers about their interest in oral PrEP and the ring. RESULTS: Among dispensers, the median age was 42 years and 77% were female. Overall, 42% of dispensers had heard of a medication for HIV prevention. Almost all dispensers reported some interest in stocking oral PrEP (92%) and the dapivirine ring (96%). Most (85%) reported they would provide oral PrEP to AGYW who requested it. Among AGYW customers, the median age was 17 years; 29% of AGYW were married or had a steady partner and 18% had children. Only 20% of AGYW had heard of a medication to prevent HIV, yet 64% and 43% expressed some interest in using oral PrEP and the dapivirine ring, respectively, after receiving information about the products. PrEP interest was higher among AGYW who were partnered and had children. CONCLUSIONS: Despite low prior awareness of PrEP among shop dispensers and AGYW, we found high levels of interest in oral PrEP and the dapivirine ring in both groups. Community-based drug shops represent a promising strategy to make HIV prevention more accessible to AGYW.

Financial incentives to promote retention in care and viral suppression in adults with HIV initiating antiretroviral therapy in Tanzania: a three-arm randomised controlled trial.

BACKGROUND: Financial incentives promote use of HIV services and might support adherence to the sustained antiretroviral therapy (ART) necessary for viral suppression, but few studies have assessed a biomarker of adherence or evaluated optimal implementation. We sought to determine whether varying sized financial incentives for clinic attendance effected viral suppression in patients starting ART in Tanzania. METHODS: In a three-arm, parallel-group, randomised controlled trial at four health facilities in Shinyanga region, Tanzania, adults aged 18 years or older with HIV who had started ART within the past 30 days were randomly assigned (1:1:1) using a tablet-based application (stratified by site) to receive usual care (control group) or to receive a cash incentive for monthly clinic attendance in one of two amounts: 10 000 Tanzanian Shillings (TZS; about US$4·50) or 22 500 TZS (about $10·00). There were no formal exclusion criteria. Participants were masked to the existence of two incentive sizes. Incentives were provided for up to 6 months via mobile health technology (mHealth) that linked biometric attendance monitoring to automated mobile payments. We evaluated the primary outcome of retention in care with viral suppression (<1000 copies per mL) at 6 months using logistic regression. This trial is registered with ClinicalTrials.gov, NCT03351556. FINDINGS: Between April 24 and Dec 14, 2018, 530 participants were randomly assigned to an incentive strategy (184 in the control group, 172 in the smaller incentive group, and 174 in the larger incentive group). All participants were included in the primary intention-to-treat analysis. At 6 months, approximately 134 (73%) participants in the control group remained in care and had viral suppression, compared with 143 (83%) in the smaller incentive group (risk difference [RD] 9·8, 95% CI 1·2 to 18·5) and 150 (86%) in the larger incentive group (RD 13·0, 4·5 to 21·5); we identified a positive trend between incentive size and viral suppression (p trend=0·0032), although the incentive groups did not significantly differ (RD 3·2, -4·6 to 11·0). Adverse events included seven (4%) deaths in the control group and 11 (3%) deaths in the intervention groups, none related to study participation. INTERPRETATION: Small financial incentives delivered using mHealth can improve retention in care and viral suppression in adults starting HIV treatment. Although further research should investigate the durability of effects from short-term incentives, these findings strengthen the evidence for implementing financial incentives within standard HIV care.
