RESUMO

Between October 2015 and August 2016, Zimbabwe conducted the Zimbabwe Population-Based HIV Impact Assessment (ZIMPHIA) cross-sectional survey to determine progress toward epidemic control. Of 25,131 eligible adults aged 15-64 years, 20,577 (81.8%) consented to face-to-face questionnaire and biomarker testing in this nationally representative household survey. Home-based rapid HIV testing was performed using Determine, First Response, and STAT-PAK as the tiebreaker. HIV-positive tests were confirmed in a laboratory using Geenius HIV-1/2; viral load (VL) was measured using Roche TaqMan and BioMerieux NucliSENS. Recency of infection was tested using Sedia HIV-1 Limiting Antigen (LAg)-Avidity. Presence of antiretroviral (ARV) drugs was detected using high performance liquid chromatography/mass spectrometry (HPLC/MS). The recent infection testing algorithm included LAg-avidity enzyme immunoassay [normalized optical density (ODn ≤1.5), VL ≥1,000 copies/mL, and absence of ARV drugs]. Weighted annual HIV incidence was compared with United Nations Joint Programme on HIV/AIDS (UNAIDS) Spectrum models estimates. Overall, 26 of 2,901 HIV-seropositive individuals had a recent infection (men, 8; women, 18). Overall weighted annual incidence among persons aged 15-64 years was 0.42% [95% confidence interval (CI): 0.25-0.59] and was 0.44% (95% CI: 0.25-0.62) for those aged 15-49 years, similar to 2016 Spectrum model estimate (0.54%, 95% CI: 0.49-0.66) for this age group. Among persons aged 15-49 years, HIV prevalence was 13.35% (95% CI: 12.71-14.02), estimated HIV-positive individuals were 968,951 (95% CI: 911,473-1,026,430), of these, 41,911 (95% CI: 37,412-44,787) were annual-new infections, and this was similar to 2016 Spectrum estimates. The observed HIV incidence in ZIMPHIA 2015-2016 validated the 2016 Spectrum estimates and Zimbabwe's progress toward epidemic control.

RESUMO

BACKGROUND: Voluntary Medical Male Circumcision (VMMC) is an effective method for HIV prevention and the World Health Organization (WHO) has recommended its expansion in 14 African countries with a high prevalence of HIV and low prevalence of male circumcision. The WHO has recently pre-qualified the PrePex device, a non-surgical male circumcision device, which reduces procedure time, can increase acceptability of VMMC, and can expand the set of potential provider cadres. The PrePex device was introduced in Zimbabwe as a way to scale-up VMMC services in the country. With the rapid scale-up of the PrePex device, as well as other similar devices, a strong surveillance system to detect adverse events (AE) is needed to monitor the safety profile of these devices. We performed a systems-based evaluation of the PrePex device AE active surveillance system in Zimbabwe. METHODS: The evaluation was based on the Centers for Disease Control and Prevention's Updated Guidelines for Evaluating Public Health Surveillance Systems. We adapted these guidelines to fit our local context. The evaluation incorporated the review of the standard operating procedures and surveillance system documents. Additionally, structured, in-person interviews were performed with key stakeholders who were users of the surveillance system at various levels. These key stakeholders were from the Ministry of Health, implementing partners, and health facilities in Harare. RESULTS: Clients were requested to return to the facility for follow-up on days 7, 14 and 49 after placement of the device. In the event of a severe AE, a standard report was generated by the health facility and relayed to the Ministry of Health Child and Care and donor agencies through predefined channels within 24 hours of diagnosis. Clinic staff reported difficulties with the amount of documentation required to follow up with clients and to report AEs. The surveillance system's acceptability among users interviewed was high, and users were motivated to identify all possible AEs related to this device. The surveillance system was purely paper-based and both duplicate and discrepant reporting forms between sites were identified. CONCLUSION: The PrePex AE active surveillance system was well accepted among participants in the health system. However, the amount of documentation which was required to follow-up with patients was a major barrier within the system, and might lead to decreased timeliness and quality of reporting. A passive surveillance system supported by electronic reporting would improve acceptance of the program.

RESUMO

BACKGROUND: In 2013, Zimbabwe's voluntary medical male circumcision (VMMC) program adopted performance-based financing (PBF) to speed progress towards ambitious VMMC targets. The $25 USD PBF intended to encourage low-paid healthcare workers to remain in the public sector and to strengthen the public healthcare system. The majority of the incentive supports healthcare workers (HCWs) who perform VMMC alongside other routine services; a small portion supports province, district, and facility levels. METHODS: This qualitative study assessed the effect of the PBF on HCW motivation, satisfaction, and professional relationships. The study objectives were to: 1) Gain understanding of the advantages and disadvantages of PBF at the HCW level; 2) Gain understanding of the advantages and disadvantages of PBF at the site level; and 3) Inform scale up, modification, or discontinuation of PBF for the national VMMC program. Sixteen focus groups were conducted: eight with HCWs who received PBF for VMMC and eight with HCWs in the same clinics who did not work in VMMC and, therefore, did not receive PBF. Fourteen key informant interviews ascertained administrator opinion. RESULTS: Findings suggest that PBF appreciably increased motivation among VMMC teams and helped improve facilities where VMMC services are provided. However, PBF appears to contribute to antagonism at the workplace, creating divisiveness that may reach beyond VMMC. PBF may also cause distortion in the healthcare system: HCWs prioritized incentivized VMMC services over other routine duties. To reduce workplace tension and improve the VMMC program, participants suggested increasing HCW training in VMMC to expand PBF beneficiaries and strengthening integration of VMMC services into routine care. CONCLUSION: In the low-resource, short-staffed context of Zimbabwe, PBF enabled rapid VMMC scale up and achievement of ambitious targets; however, side effects make PBF less advantageous and sustainable than envisioned. Careful consideration is warranted in choosing whether, and how, to implement PBF to prioritize a public health program.

RESUMO

To date, there is no research on voluntary medical male circumcision (VMMC) catchment areas or the relationship between distance to a VMMC facility and attendance at a post-operative follow-up visit. We analyzed data from a randomly selected subset of males self-seeking circumcision at one of 16 participating facilities in Nyanza Province, Kenya between 2008 and 2010. Among 1437 participants, 46.7 % attended follow-up. The median distance from residence to utilized facility was 2.98 km (IQR 1.31-5.38). Nearly all participants (98.8 %) lived within 5 km from a facility, however, 26.3 % visited a facility more than 5 km away. Stratified results demonstrated that among those utilizing fixed facilities, greater distance was associated with higher odds of follow-up non-attendance (OR5.01-10km vs. 0-1km = 1.71, 95 % CI 1.08, 2.70, p = 0.02; OR>10km vs. 0-1 km = 2.80, 95 % CI 1.26, 6.21, p = 0.01), adjusting for age and district of residence. We found 5 km marked the threshold distance beyond which follow-up attendance significantly dropped. These results demonstrate distance is an important predictor of attending follow-up, and this relationship appears to be modified by facility type.

RESUMO

This paper discusses characteristics that are associated with enhanced maternal and child health (MCH) epidemiology functioning in state health agencies. The concept of the "MCH Epidemiology Effort" is introduced as "the epidemiologic work carried out by multiple units and agencies aimed at informing program planning and policy development on behalf of women, children and families." This concept focuses attention on MCH epidemiology functioning at the organizational level rather than on individual MCH epidemiologists. The analysis used data from all 50 states and the District of Columbia. Each state participated in a telephone interview and submitted material that demonstrated the breadth, depth, and capacity of its MCH Epidemiology Effort. Several organizations, including the Council for State and Territorial Epidemiologists, the Health Resources and Services Administration/Maternal and Child Health Bureau, and the Centers for Disease Control and Prevention provided additional secondary data. The outcome for analysis was a three-category measure of MCH epidemiology functioning. The findings are consistent with, and add specificity to, those from prior assessments. In a multivariable model, agenda-setting by consensus, involvement of external stakeholders, the total of doctorally trained staff, and accessing CDC assignees or other staff were all significantly related to higher level MCH epidemiology functioning (ORs of 6.1, 6.6, 2.5, and 6.4, respectively; P<0.05). Organizational visibility of the MCH Epidemiology Effort and a data environment marked by routine data-sharing and data integration were marginally related. We provide recommendations for action at the state and federal level for advancing evidence-based decision-making in maternal and child health.
