Health care services for survivors of gender-based violence: a community and clinic-based intervention in Zambézia province, Mozambique

Moçambique introduziu directrizes para serviços integrados de violência baseada no género (VBG) em 2012. Em 2017, formámos prestadores de serviços em serviços empáticos e de apoio aos sobreviventes da VBG e introduzimos serviços domiciliários para sobreviventes que não têm acompanhamento. As proporções de taxas de visitas clínicas foram comparadas antes e depois do início da intervenção, utilizando testes de significância exata. Foram revistos dados de 1.806 sobreviventes da VBG, com um total de 2.005 eventos. A idade mediana foi de 23 anos (IQR 17-30) e 89% eram mulheres. Entre aqueles que relataram violência, 69% relataram violência física, 18% relataram violência sexual (VS) e 12% relataram violência psicológica. As taxas de comportamento de procura de cuidados foram maiores no período de intervenção (razão de taxas 1,31 [IC95%: 1,18-1,46]); p < 0,01. Entre aqueles elegíveis para profilaxia pós-exposição (PEP), 94% iniciaram a PEP. A adesão ao novo teste de HIV melhorou em pontos percentuais em 34% (14% para 48%), 34% (8% para 42%) e 26% (5% para 31%) em 1, 3 e 6 meses, respectivamente . A intervenção levou a um aumento na taxa de sobreviventes de VBG que procuram serviços de saúde e melhorou as taxas de cuidados de acompanhamento entre os sobreviventes de VS que iniciaram a PEP. O reforço do aconselhamento sobre adesão à PEP continua a ser crucial para melhorar os serviços de VBG.

The effect of a Mentor Mothers program on prevention of vertical transmission of HIV outcomes in Zambézia Province, Mozambique: a retrospective interrupted time series analysis

Introduction: Mentor Mothers (MM) provide peer support to pregnant and postpartum women living with HIV (PPWH) and their infants with perinatal HIV exposure (IPE) throughout the cascade of prevention of vertical transmission (PVT) services. MM were implemented in Zambézia Province, Mozambique starting in August 2017. This evaluation aimed to determine the effect of MM on PVT outcomes. Methods: A retrospective interrupted time series analysis was done using routinely collected aggregate data from 85 public health facilities providing HIV services in nine districts of Zambézia. All PPWH (and their IPE) who initiated antiretroviral therapy (ART) from August 2016 through April 2019 were included. Outcomes included the proportion per month per district of: PPWH retained in care 12 months after ART initiation, PPWH with viral suppression and IPE with HIV DNA PCR test positivity by 9 months of age. The effect of MM on outcomes was assessed using logistic regression. Results: The odds of 12-month retention increased 1.5% per month in the pre-MM period, compared to a monthly increase of 7.6% with-MM (35-61% pre-MM, 56-72% with-MM; p < 0.001). The odds of being virally suppressed decreased by 0.9% per month in the pre-MM period, compared to a monthly increase of 3.9% with-MM (49-85% pre-MM, 59-80% with-MM; p < 0.001). The odds of DNA PCR positivity by 9 months of age decreased 8.9% per month in the pre-MM period, compared to a monthly decrease of 0.4% with-MM (0-14% pre-MM, 4-10% with-MM; p < 0.001). The odds of DNA PCR uptake (the proportion of IPE who received DNA PCR testing) by 9 months of age were significantly higher in the with-MM period compared to the pre-MM period (48-100% pre-MM, 87-100% with-MM; p < 0.001). Conclusions: MM services were associated with improved retention in PVT services and higher viral suppression rates among PPWH. While there was ongoing but diminishing improvement in DNA PCR positivity rates among IPE following MM implementation, this might be explained by increased uptake of HIV testing among high-risk IPE who were previously not getting tested. Additional efforts are needed to further optimize PVT outcomes, and MM should be one part of a comprehensive strategy to address this critical need.

CD4 Trends with evolving treatment initiation policies among children living with HIV in zambézia province, mozambique, 2012-2018

Background: Historically, antiretroviral therapy (ART) initiation was based on CD4 criteria, but this has been replaced with "Test and Start" wherein all people living with HIV are offered ART. We describe the baseline immunologic status among children relative to evolving ART policies in Mozambique. Methods: This retrospective evaluation was performed using routinely collected data. Children living with HIV (CL aged 5-14 years) with CD4 data in the period of 2012-2018 were included. ART initiation "policy periods" corresponded to implementation of evolving guidelines: in period 1 (2012-2016), ART was recommended for CD4 <350 cells/mm3; during period 2 (2016-2017), the CD4 threshold increased to <500 cells/mm3; Test and Start was implemented in period 3 (2017-2018). We described temporal trends in the proportion of children with severe immunodeficiency (CD4 <200 cells/mm3) at enrollment and at ART initiation. Multivariable regression models were used to estimate associations with severe immunodeficiency. Results: The cohort included 1815 children with CD4 data at enrollment and 1922 at ART initiation. The proportion of children with severe immunodeficiency decreased over time: 20% at enrollment into care in period 1 vs. 16% in period 3 (P = 0.113) and 21% at ART initiation in period 1 vs. 15% in period 3 (P = 0.004). Children initiating ART in period 3 had lower odds of severe immunodeficiency at ART initiation compared with those in period 1 [adjusted odds ratio (aOR) = 0.67; 95% CI: 0.51 to 0.88]. Older age was associated with severe immunodeficiency at enrollment (aOR = 1.13; 95% CI: 1.06 to 1.20) and at ART initiation (aOR = 1.14; 95% CI: 1.08 to 1.21). Conclusions: The proportion of children with severe immunodeficiency at ART initiation decreased alongside more inclusive ART initiation guidelines. Earlier treatment of children living with HIV is imperative.
