Provider- and patient-level costs associated with providing antiretroviral therapy during the postpartum phase to women living with HIV in South Africa: A cost comparison of three postpartum models of care.

OBJECTIVE: To compare the unit and total costs of three models of ART care for mother-infant pairs during the postpartum phase from provider and patient's perspectives: (i) local standard of care with women in general ART services and infants at well-baby clinics; (ii) women and infants continue to receive care through an integrated maternal and child care approach during the postpartum breastfeeding period; and (iii) referral of women directly to community adherence clubs with their infants receiving care at well-baby clinics. METHODS: Capital and recurrent cost data (relating to buildings, furniture, equipment, personnel, overheads, maintenance, medication, diagnostic tests and immunisations) were collected from a provider's perspective at six sites in Cape Town, South Africa. Patient time, collected via time-and-motion observation and questionnaires, was used to estimate patient perspective costs and is comprised of lost productivity time, time spent travelling and the direct cost of travelling. RESULTS: The cost of postpartum ART visits under models I, II and III was US $13, US $10 and US $7 per visit for a mother-infant pair, respectively, in 2018 US$. The annual costs for the mother-infant pair utilising the average visit frequencies (a mean of 4.5, 6.9 and 6.7 visits postpartum for models I, II and III, respectively) including costs for infant immunisations, visits, medication and diagnostic tests for both mothers and infants were: I - US $222, II - US $335 and III - US $249. Sensitivity analysis to assess the impact of visit frequency on visit cost showed that Model I annual costs would be most costly if visit frequency was equalised. CONCLUSION: This comparative analysis of three models of care provides novel data on unit costs and insight into the costs to provide ART and care to mother-infant pairs during the delicate postpartum phase. These costs may be used to help make decisions around integrated services models and differentiated service delivery for postpartum WLH and their children.

OBJECTIF: Comparer le coût et unitaire et total de trois modèles de soins ART pour les paires mère-enfant pendant la phase post-partum selon les perspectives du fournisseur et du patient: (I) - normes locales des soins avec les femmes dans les services généraux de l'ART et les nourrissons dans les cliniques de bien-être pour bébés; (II) - les femmes et les nourrissons continuent de recevoir des soins via une approche intégrée de soins maternels et infantiles pendant la période d'allaitement post-partum; et (III) - orientation des femmes directement vers les clubs d'adhésion communautaires, leurs nourrissons recevant des soins dans les cliniques de bien-être pour bébés pour bébés. MÉTHODES: Les données sur les coûts d'investissement et les coûts récurrents (relatifs aux bâtiments, au mobilier, à l'équipement, au personnel, aux frais généraux, à l'entretien, aux médicaments, aux tests de diagnostic et aux vaccinations) ont été recueillies selon le point de vue du prestataire sur six sites à Cape Town, en Afrique du Sud. Le temps du patient, recueilli via l'observation du temps et des mouvements et des questionnaires, a été utilisé pour estimer les coûts selon le point de vue du patient, et comprend le temps de productivité perdu, le temps passé en déplacement et le coût direct du déplacement. RÉSULTATS: Le coût des visites ART post-partum dans les modèles I, II et III était respectivement de 13 USD, 10 USD et 7 USD par visite pour une paire mère-enfant en USD de 2018. Les coûts annuels pour la paire mère-enfant en utilisant la fréquence moyenne des visites (une moyenne de 4,5 ; 6,9 et 6,7 visites post-partum pour les modèles I, II et III respectivement), y compris les coûts des vaccinations infantiles, des visites, des médicaments et des tests diagnostiques pour les mères et les nourrissons étaient: I - 222 USD, II - 335 USD et III - 249 USD. L'analyse de sensibilité pour évaluer l'impact de la fréquence des visites sur le coût des visites a montré que les coûts annuels du modèle I seraient les plus élevés si la fréquence des visites était égalisée. CONCLUSIONS: Cette analyse comparative de trois modèles de soins fournit de nouvelles données sur les coûts unitaires et un aperçu des coûts de fourniture de l'ART et de soins aux paires mère-enfant pendant la phase délicate du post-partum. Ces coûts peuvent être utilisés pour aider à la prise des décisions concernant les modèles de services intégrés et la prestation de services différenciés pour les femmes en période de post-partum et leurs enfants.

Does treatment collection and observation each day keep the patient away? An analysis of the determinants of adherence among patients with Tuberculosis in South Africa.

Directly observed treatment short course (DOTS) has been the recommended strategy for Tuberculosis (TB) control since 1995. Developed as an alternative to inpatient treatment, it involves observation of patients' medication intake to promote adherence. However, the burden of daily clinic visits may affect access to care. Using a mixed methods approach, we consider whether (1) non-adherence differs systematically between patients required to make daily clinic visits and patients cared for under less frequent clinic visits and (2) the association between frequency of required clinic visits and adherence depends on affordability and acceptability of care. Data were collected in facility exit interviews with 1200 TB patients in two rural and two urban sub-districts in South Africa. Additionally, 17 in-depth interviews were completed with TB patients. After controlling for socioeconomic and demographic factors, patient type (new or retreatment) and treatment duration, regression analyses showed that daily attending patients were over twice as likely to report a missed clinic visit (P < 0.001) or a missed dose of treatment (P = 0.002) compared with patients required to attend clinics for treatment collection less frequently. Missed visits increased with treatment duration (P = 0.01). The significant interaction between clinic visit frequency and treatment duration indicated that sustaining daily visits over time may become increasingly difficult over the course of treatment. The qualitative analysis identified treatment cost and duration, patients' physical condition and varying social contexts (family, community and work) as important influences on adherence. These findings suggest that strategies involving daily clinic visits may require reconsideration if resources for TB care are to be used efficiently. The adoption of approaches that place patient interests at the centre of TB treatment delivery would appear to be of high priority, particularly in countries where TB prevalence is high and resources for TB care are highly constrained.

The quality of HIV testing services for adolescents in Cape Town, South Africa: do adolescent-friendly services make a difference?

We used adolescent simulated clients to evaluate whether HIV testing services in clinics participating in an adolescent-friendly initiative in Cape Town were superior to regular clinic services. We found improved accessibility to HIV testing, but no impact on adolescent's experience of negative attitudes from health workers and confidentiality breaches.

High levels of risk behavior among people living with HIV Initiating and waiting to start antiretroviral therapy in Cape Town South Africa.

Baseline data were collected in Cape Town during 2006 to study if patients on combination antiretroviral therapy (ART) experience decreased inhibition to avoid risky sexual behavior. A total of 924 HIV-positive individuals were recruited; 520 who initiated ART within 3 months and 404 waiting for ART. Nearly half of men (40.1%) and women (46.3%) reported having unprotected sex their last time. Men and women who did not disclose their HIV status to their partner [Odds ration (OR)=2.57 (95% CI: 1.22-5.50) and 2.84 (95% CI: 1.84-4.39), respectively], and those with ambivalent perception about the relationship between ART and HIV transmission [OR=2.08 (95% CI: 1.00-4.30) and 2.39 (95% CI: 1.50-3.84), respectively], were twice as likely to have had unprotected sex their last time. Results suggest an urgent need to strengthen prevention interventions among HIV-positive individuals on and about to start ART in this setting.
