To meet UNAIDS’ 90–90–90 treatment goals, effective approaches to HIV testing services (HTSs) are urgently needed. In 2015, a cross-sectional study was conducted to evaluate effectiveness and feasibility of partner notification for HTS in Tanzania. Men and women newly diagnosed with HIV were enrolled as index clients, listed sexual partners, and given options to notify and link their partners to HTS. Of 653 newly diagnosed individuals, 390 index clients were enrolled, listed 438 sexual partners, of whom 249 (56.8%) were successfully referred. Of 249 partners reaching the facilities, 96% tested for HIV, 148 (61.9%) tested HIV+ (all newly diagnosed), and 104 (70.3%) of partners testing positive were enrolled into HIV care and treatment. Results showed good acceptability, feasibility and effectiveness, as evidenced by high uptake of partner notification among newly diagnosed individuals, over half of listed partners successfully referred, and a very high positivity rate among referred sexual partners.

A growing evidence base supports expansion of partner notification in HIV testing services (HTS) in sub-Saharan Africa. In 2015, a cross-sectional study was conducted in Njombe region, Tanzania, to evaluate partner notification within facility-based HTS. Men and women newly diagnosed with HIV were enrolled as index clients and asked to list current or past sexual partners for referral to HTS. Successful partner referral was 2.5 times more likely among married compared to unmarried index clients and 2.2 times more likely among male compared to female index clients. In qualitative analysis, male as well as female index clients mentioned difficulties notifying past or casual partners, and noted disease symptoms as a motivating factor for HIV testing. Female index clients mentioned gender-specific challenges to successful referral. Women may need additional support to overcome challenges in the partner notification process. In addition to reducing barriers to partner notification specific to women, a programmatic emphasis on social strengths of males in successfully referring partners should be considered.

Preeclampsia and eclampsia (PE/E) are major contributors to maternal and neonatal deaths in developing countries, associated with 10–15% of direct maternal deaths and nearly a quarter of stillbirths and newborn deaths, many of which are preventable with improved care. We present results related to WHO-recommended interventions for screening and management of PE/E during antenatal care (ANC) and labor and delivery (L & D) from a study conducted in six sub-Saharan African countries. From 2010 to 2012, cross-sectional studies which directly observed provision of ANC and L & D services in six sub-Saharan African countries were conducted. Results from 643 health facilities of different levels in Ethiopia (n = 19), Kenya (n = 509), Madagascar (n = 36), Mozambique (n = 46), Rwanda (n = 72), and Tanzania (n = 52), were combined for this analysis. While studies were sampled separately in each country, all used standardized observation checklists and inventory assessment tools. 2920 women receiving ANC and 2689 women in L & D were observed. Thirty-nine percent of ANC clients were asked about PE/E danger signs, and 68% had their blood pressure (BP) taken correctly (range 48–96%). Roughly half (46%) underwent testing for proteinuria. Twenty-three percent of women in L & D were asked about PE/E danger signs (range 11–34%); 77% had their BP checked upon admission (range 59–85%); and 6% had testing for proteinuria. Twenty-five cases of severe PE/E were observed: magnesium sulfate (MgSO4) was used in 15, not used in 5, and for 5 use was unknown. The availability of MgSO4 in L & D varied from 16% in Ethiopia to 100% in Mozambique. Observed ANC consultations and L & D cases showed low use of WHO-recommended practices for PE/E screening and management. Availability of MgSO4 was low in multiple countries, though it was on the essential drug list of all surveyed countries. Country programs are encouraged to address gaps in screening and management of PE/E in ANC and L & D to contribute to lower maternal and perinatal mortality.

Despite emerging qualitative evidence of gendered community health worker (CHW) experience, few quantitative studies examine CHW gender differentials. The launch of a maternal, newborn, and child health (MNCH) CHW cadre in Morogoro Region, Tanzania enlisting both males and females as CHWs, provides an opportunity to examine potential gender differences in CHW knowledge, health promotion activities and client acceptability. All CHWs who received training from the Integrated MNCH Program between December 2012 and July 2013 in five districts were surveyed and information on health promotion activities undertaken drawn from their registers. CHW socio-demographic characteristics, knowledge, and health promotion activities were analyzed through bi- and multivariate analyses. Composite scores generated across ten knowledge domains were used in ordered logistic regression models to estimate relationships between knowledge scores and predictor variables. Thematic analysis was also undertaken on 60 purposively sampled semi-structured interviews with CHWs, their supervisors, community leaders, and health committee members in 12 villages from three districts. Of all CHWs trained, 97 % were interviewed (n = 228): 55 % male and 45 % female. No significant differences were observed in knowledge by gender after controlling for age, education, date of training, marital status, and assets. Differences in number of home visits and community health education meetings were also not significant by gender. With regards to acceptability, women were more likely to disclose pregnancies earlier to female CHWs, than male CHWs. Men were more comfortable discussing sexual and reproductive concerns with male, than female CHWs. In some cases, CHW home visits were viewed as potentially being for ulterior or adulterous motives, so trust by families had to be built. Respondents reported that working as female–male pairs helped to address some of these dynamics. Male and female CHWs in this study have largely similar knowledge and health promotion outputs, but challenges in acceptance of CHW counseling for reproductive health and home visits by unaccompanied CHWs varied by gender. Programs that pair male and female CHWs may potentially overcome gender issues in CHW acceptance, especially if they change gender norms rather than solely accommodate gender preferences.

Complex health interventions must incorporate user preferences to maximize their potential effectiveness. Discrete choice experiments (DCEs) quantify the strength of user preferences and identify preference heterogeneity across users. We present the process of using a DCE to supplement conventional qualitative formative research in the design of a demand creation intervention for voluntary medical male circumcision (VMMC) to prevent HIV in Tanzania. The VMMC intervention was designed within a 3-month formative phase. In-depth interviews (n = 30) and participatory group discussions (n = 20) sought to identify broad setting-specific barriers to and facilitators of VMMC among adult men. Qualitative results informed the DCE development, identifying the role of female partners, service providers’ attitudes and social stigma. A DCE among 325 men in Njombe and Tabora, Tanzania, subsequently measured preferences for modifiable VMMC service characteristics. The final VMMC demand creation intervention design drew jointly on the qualitative and DCE findings. While the qualitative research informed the community mobilization intervention, the DCE guided the specific VMMC service configuration. The significant positive utilities (u) for availability of partner counselling (u = 0.43, p < 0.01) and age-separated waiting areas (u = 0.21, p < 0.05) led to the provision of community information booths for partners and provision of age-separated waiting areas. The strong disutility of female healthcare providers (u = − 0.24, p < 0.01) led to re-training all providers on client-friendliness. This is, to our knowledge, the first study documenting how user preferences from DCEs can directly inform the design of a complex intervention. The use of DCEs as formative research may help increase user uptake and adherence to complex interventions.

While the lifetime risk of developing cervical cancer (CaCx) and acquiring HIV is high for women in Tanzania, most women have not tested for HIV in the past year and most have never been screened for CaCx. Good management of both diseases, which have a synergistic relationship, requires integrated screening, prevention, and treatment services. The aim of this analysis is to assess the acceptability, feasibility and effectiveness of integrating HIV testing into CaCx prevention services in Tanzania, so as to inform scale-up strategies. We analysed 2010 – 2013 service delivery data from 21 government health facilities in four regions of the country, to examine integration of HIV testing within newly introduced CaCx screening and treatment services, located in the reproductive and child health (RCH) section of the facility. Analysis included the proportion of clients offered and accepting the HIV test, reasons why testing was not offered or was declined, and HIV status of CaCx screening clients. A total of 24,966 women were screened for CaCx; of these, approximately one-quarter (26%) were referred in from HIV care and treatment clinics. Among the women of unknown HIV status (n = 18,539), 60% were offered an HIV test. The proportion of women offered an HIV test varied over time, but showed a trend of decline as the program expanded. Unavailability of HIV test kits at the facility was the most common reason for a CaCx screening client not to be offered an HIV test (71% of 6,321 cases). Almost all women offered (94%) accepted testing, and 5% of those tested (582 women) learned for the first time that they were HIV-positive. Integrating HIV testing into CaCx screening services was highly acceptable to clients and was an effective means of reaching HIV-positive women who did not know their status; effectiveness was limited, however, by shortages of HIV test kits at facilities. Integration of HIV testing into CaCx screening services should be prioritized in HIV-endemic settings, but more work is needed to eliminate logistical barriers. The coverage of CaCx screening among HIV care and treatment-enrolled women in Tanzania may be low and should be examined.
