Access to and use of health and social services among people who inject drugs in two urban areas of Mozambique, 2014: qualitative results from a formative assessment.

BACKGROUND: Prior to 2014, data about health seeking behaviors or service uptake for People who inject drugs (PWID) in Mozambique did not exist. We present the results from the formative assessment component of the Biological and Behavioral Survey (BBS). METHODS: Standardized interview guides were used during key informant interviews (KII) and focus group discussions (FGD) in Maputo and Nampula/Nacala to discuss issues related to risk behaviors and access to and utilization of health and social services by PWID. The target sample size was not defined a priori, but instead KII and FGD were conducted until responses reached saturation. Data analysis was based on the principles of grounded theory related to qualitative research. RESULTS: Eighty-eight respondents, ages 15 to 60, participated in KIIs and FGDs. Participants were majority male from diverse income and education levels and included current and former PWID, non-injection drug users, health and social service providers, peer educators, and community health workers. Respondents reported that PWID engage in high-risk behaviors such as needle and syringe sharing, exchange of sex for drugs or money, and low condom use. According to participants, PWID would rather rent, share or borrow injection equipment at shooting galleries than purchase them due to stigma, fear of criminalization, transportation and purchase costs, restricted pharmacy hours, personal preference for needle sharing, and immediacy of drug need. Barriers to access and utilization of health and social services include distance, the limited availability of programs for PWID, lack of knowledge of the few programs that exist, concerns about the quality of care provided by health providers, lack of readiness as a result of addiction and perceived stigma related to the use of mental health services offering treatment to PWID. CONCLUSIONS: Mozambique urgently needs to establish specialized harm reduction programs for PWID and improve awareness of available resources. Services should be located in hot spot areas to address issues related to distance, transportation and the planning required for safe injection. Specific attention should go to the creation of PWID-focused health and social services outside of state-sponsored psychiatric treatment centers.

High prevalence of HIV, HBsAg and anti-HCV positivity among people who injected drugs: results of the first bio-behavioral survey using respondent-driven sampling in two urban areas in Mozambique.

BACKGROUND: Few countries in sub-Saharan Africa know the magnitude of their HIV epidemic among people who inject drugs (PWID). This was the first study in Mozambique to measure prevalence of HIV, HBV, and HCV, and to assess demographic characteristics and risk behaviors in this key population. METHODS: We used respondent-driven sampling (RDS) to conduct a cross-sectional behavioral surveillance survey of PWID in two cities of Mozambique lasting six months. Participants were persons who had ever injected drugs without a prescription. Participants completed a behavioral questionnaire and provided blood specimens for HIV, hepatitis B surface antigen (HBsAg) and hepatitis C virus antibody (anti-HCV) testing. We performed RDS-adjusted analysis in R 3.2 using RDSAT 7.1 weights. RESULTS: We enrolled 353 PWID in Maputo and 139 in Nampula/Nacala; approximately 95% of participants were men. Disease prevalence in Maputo and Nampula/Nacala, respectively, was 50.1 and 19.9% for HIV, 32.1 and 36.4% for HBsAg positivity, and 44.6 and 7.0% for anti-HCV positivity. Additionally, 8% (Maputo) and 28.6% (Nampula/Nacala) of PWID reported having a genital sore or ulcer in the 12 months preceding the survey. Among PWID who injected drugs in the last month, 50.3% (Maputo) and 49.6% (Nampula/Nacala) shared a needle at least once that month. Condomless sex in the last 12 months was reported by 52.4% of PWID in Maputo and 29.1% in Nampula/Nacala. Among PWID, 31.6% (Maputo) and 41.0% (Nampula/Nacala) had never tested for HIV. In multivariable analysis, PWID who used heroin had 4.3 (Maputo; 95% confidence interval [CI]: 1.2, 18.2) and 2.3 (Nampula/Nacala; 95% CI: 1.2, 4.9) greater odds of having HIV. CONCLUSION: Unsafe sexual behaviors and injection practices are frequent among PWID in Mozambique, and likely contribute to the disproportionate burden of disease we found. Intensified efforts in prevention, care, and treatment specific for PWID have the potential to limit disease transmission.

Prevalence of HIV, viral hepatitis B/C and tuberculosis and treatment outcomes among people who use drugs: Results from the implementation of the first drop-in-center in Mozambique.

BACKGROUND: People who use drugs (PWUD) which includes both people who inject drugs (PWID) and non-injection drug users (NIDU) are marginalized, experience high levels of stigma and discrimination, and are likely to have challenges with accessing health services. Mozambique implemented the first drop-in center (DIC) for PWUD in Maputo City in 2018. This analysis aims to assess the prevalence of HIV, viral hepatitis B (HBV) and C (HCV) and tuberculosis (TB) among PWUD, and assess their linkage to care and associated correlates. METHODS: We conducted a cross-sectional retrospective analysis of routine screening data collected from the first visit at the drop-in center (DIC) during the period of May 2018 to November 2019 (18 months). Descriptive and multivariable logistic regression analysis were conducted to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) of HIV, HBV, HCV and TB infections among PWID and NIDU. Cox proportional hazards models of determinants were used to estimate time from HIV diagnosis to linkage to care for PWUD. RESULTS: A total of 1,818 PWUD were screened at the DIC, of whom 92.6% were male. The median age was 27 years (range:14-63). Heroin was the most consumed drug (93.8%), and among people who used it, 15.5% injected it. Prevalence of HIV (43.9%), HCV (22.6%) and HBV (5.9%) was higher among PWID (p<0.001). Linkage to HIV care was observed in 40.5% of newly diagnosed PWID. Factors associated with shorter time to linkage to care included drug injection (aHR=1.6) and confirmed TB infection (aHR=2.9). CONCLUSION: This was the first analysis conducted on the implementation of the DIC in Mozambique and highlights the importance of targeted services for this high-risk population. Our analysis confirmed a high prevalence of HIV, HBV and HCV, and highlight the challenges with linkage to care among PWID. The expansion of DIC locations to other high-risk localities to enhance HIV testing, treatment services and linkage to care to reduce ongoing transmission of HIV, HBV, HCV and TB and improve health outcomes.
