Positive attitudes toward adoption of a multi-component intervention strategy aimed at improving HIV outcomes among adolescents and young people in Nampula, Mozambique: perspectives of HIV care providers.

BACKGROUND: Service providers' attitudes toward interventions are essential for adopting and implementing novel interventions into healthcare settings, but evidence of evaluations in the HIV context is still limited. This study is part of the CombinADO cluster randomized trial (ClinicalTrials.gov NCT04930367), which is investigating the effectiveness of a multi-component intervention package (CombinADO strategy) aimed at improving HIV outcomes among adolescents and young adults living with HIV (AYAHIV) in Mozambique. In this paper we present findings on key stakeholder attitudes toward adopting study interventions into local health services. METHODS: Between September and December 2021, we conducted a cross-sectional survey with a purposive sample of 59 key stakeholders providing and overseeing HIV care among AYAHIV in 12 health facilities participating in the CombinADO trial, who completed a 9-item scale on attitudes towards adopting the trial intervention packages in health facilities. Data were collected in the pre-implementation phase of the study and included individual stakeholder and facility-level characteristics. We used generalized linear regression to examine the associations of stakeholder attitude scores with stakeholder and facility-level characteristics. RESULTS: Overall, service-providing stakeholders within this setting reported positive attitudes regarding adopting intervention packages across study clinic sites; the overall mean total attitude score was 35.0 ([SD] = 2.59, Range = [30-41]). The study package assessed (control or intervention condition) and the number of healthcare workers delivering ART care in participating clinics were the only significant explanatory variables to predict higher attitude scores among stakeholders (ß = 1.57, 95% CI = 0.34-2.80, p = 0.01 and ß = 1.57, 95% CI = 0.06-3.08, p = 0.04 respectively). CONCLUSIONS: This study found positive attitudes toward adopting the multi-component CombinADO study interventions among HIV care providers for AYAHIV in Nampula, Mozambique. Our findings suggest that adequate training and human resource availability may be important in promoting the adoption of novel multi-component interventions in healthcare services by influencing healthcare provider attitudes.

Mother-child separation among women living with HIV and their children in the first four years postpartum in South Africa.

OBJECTIVES: Mother-child pairs may separate during early life, yet the health impacts thereof are unclear. We explored the patterns and impact of separation among women living with HIV (WLHIV) and their children in South Africa. METHODS: WLHIV who had initiated antiretroviral therapy (ART) during pregnancy received HIV viral load (VL) testing and completed a timeline questionnaire of mother-child separation since delivery at 3-5 years post-partum. Health care usage was abstracted from routine medical records. We examined associations between separation and (a) maternal health outcomes (engagement in HIV care and HIV viral suppression, [VS]) and (b) child health outcomes (post-breastfeeding HIV testing and immunisation completion), using logistic regression. RESULTS: Of 346 mother-child pairs (median maternal age at antenatal ART initiation, 28 years), 24% were ever separated (median time to first separation 20 months, interquartile range [IQR] 9, 31). Most separated children were living with their grandmothers (65/83, 78%). Mothers who ever separated were younger, and more likely to be employed, and to reside in informal housing than those who never separated. Any separation reduced the odds of VS ≤ 50 copies/mL at four years post-partum (odds ratio 0.57; 95% CI 0.34-0.93); associations were similar for VL ≤ 1000 copies/mL and maternal engagement in care. No association was found between separation and child confirmatory HIV testing or immunisation completion. CONCLUSIONS: In this setting, mother-child separation is common in the first four years of life and appears associated with suboptimal maternal outcomes. Further research is required to understand the drivers and implications of mother-child separation.

OBJECTIFS: Les couples mère-enfant peuvent être séparés au début de la vie, mais les effets sur la santé ne sont pas clairs. Nous avons exploré les modèles et l'impact de la séparation chez les femmes vivant avec le VIH (PVVIH) et leurs enfants en Afrique du Sud. MÉTHODES: Les PVVIH qui avaient initié un traitement antirétroviral (ART) pendant la grossesse ont subi un test de charge virale du VIH (CV) et ont rempli un questionnaire chronologique sur la séparation mère-enfant depuis l'accouchement à 3-5 ans post-partum. L'utilisation des soins de santé a été extraite des dossiers médicaux de routine. Nous avons examiné les associations entre la séparation et (a) les résultats pour la santé maternelle (engagement dans les soins du VIH et la suppression virale du VIH [SV]) et (b) les résultats pour la santé de l'enfant (dépistage du VIH après l'allaitement et achèvement de la vaccination), en utilisant la régression logistique. RÉSULTATS: Sur 346 couples mère-enfant (âge maternel médian au début de l'ART prénatal, 28 ans), 24% ont été séparés (délai médian jusqu'à la première séparation 20 mois, intervalle interquartile [IQR] 9 à 31). La plupart des enfants séparés vivaient avec leurs grands-mères (65/83, 78%). Les mères qui ont vécu une telle séparation étaient plus jeunes et plus susceptibles d'avoir un emploi et de vivre dans un logement informel que celles qui ne l'ont jamais vécue. Toute séparation réduisait les chances de SV ≤50 copies/mL à quatre ans après l'accouchement (odds ratio 0,57; IC95%: 0,34-0,93); les associations étaient similaires pour la CV ≤1000 copies/mL et l'engagement de la mère dans les soins. Aucune association n'a été trouvée entre la séparation et le test de confirmation du VIH chez l'enfant ou l'achèvement de la vaccination. CONCLUSIONS: Dans ce contexte, la séparation mère-enfant est courante au cours des quatre premières années de la vie et semble associée à des résultats maternels sous-optimaux. Des recherches supplémentaires sont nécessaires pour comprendre les facteurs et les implications de la séparation mère-enfant.
