          The delivery of HIV care in the initial rapid scale-up of HIV care and treatment was based on existing clinic-based models, which are common in highly resourced settings and largely undifferentiated for individual needs. A new framework for treatment based on variable intensities of care tailored to the specific needs of different groups of individuals across the cascade of care is proposed here. Service intensity is characterised by four delivery components: (i) types of services delivered, (ii) location of service delivery, (iii) provider of health services and (iv) frequency of health services. How these components are developed into a service delivery framework will vary across countries and populations, with the intention being to improve acceptability and care outcomes. The goal of getting more people on treatment before they become ill will necessitate innovative models of delivering both testing and care. As HIV programmes expand treatment eligibility, many people entering care will not be ‘patients’ but healthy, active and productive members of society 1. To take the framework to scale, it will be important to: (i) define which individuals can be served by an alternative delivery framework; (ii) strengthen health systems that support decentralisation, integration and task shifting; (iii) make the supply chain more robust; and (iv) invest in data systems for patient tracking and for programme monitoring and evaluation.

          La délivrance des soins du VIH dans le déploiement initial rapide des soins et du traitement du VIH a été basée sur des modèles existants dans les cliniques, qui sont courants dans les régions bénéficiant d’importantes ressources et largement indifférenciées pour les besoins individuels. Un nouveau cadre est proposé ici pour le traitement basé selon les intensités variables de soins, adaptés aux besoins spécifiques des différents groupes de personnes à travers la cascade de soins. L’intensité des services est caractérisée par quatre éléments de délivrance: (1) les types de services délivrés, (2) l’emplacement de la délivrance des services, (3) Les prestataires des services de santé et (4) la fréquence des services de santé. La façon dont ces éléments sont développés dans un cadre de prestation de services peut varier selon les pays et les populations, l’intention étant d’améliorer les résultats d’acceptabilité et des soins. Le but d’obtenir plus de personnes sous traitement avant qu’ils ne tombent malades nécessitera des modèles innovateurs de prestation à la fois pour dépistage et pour les soins. Comme les programmes VIH étendent l’éligibilité au traitement, beaucoup de gens qui entrent dans les soins ne seront pas des “malades- mais des éléments sains de la société, actifs et productifs. Afin de tenir le cadre à l’échelle, il sera important de: (1) définir les individus qui peuvent être traités par un cadre alternatif de prestation, (2) renforcer les systèmes de santé qui soutiennent la décentralisation, l’intégration et le transfert des tâches; (3) rendre la chaîne d’approvisionnement plus robuste et (4) investir dans des systèmes de données pour le suivi des patients et pour le suivi et l’évaluation du programme.

          Los servicios de atención del VIH durante el inicio de la primera etapa de rápida expansión del tratamiento y cuidados del VIH estaban basados en modelos clínicos existentes, comunes en lugares con abundancia de recursos y poco diferenciados en cuanto a necesidades individuales. Aquí se propone un nuevo marco para el tratamiento basado en intensidades variables de cuidados, hecho a medida según las necesidades específicas de los diferentes grupos de individuos a lo largo del tratamiento. La intensidad del servicio se caracteriza por cuatro componentes de entrega: (1) tipología de los servicios ofrecidos, (2) lugar de entrega de los servicios, (3) proveedor de los servicios sanitarios, y (4) frecuencia de los servicios sanitarios. El cómo estos componentes conforman un marco de entrega de servicios variará según el país y la población, con la intención de mejorar la aceptabilidad y los resultados de los cuidados. El objetivo de conseguir que más personas reciban tratamiento antes de que enfermen requerirá de modelos innovadores en la oferta tanto de pruebas para detección como de los cuidados. A medida que los programas para el VIH expandan los criterios de elegibilidad para el tratamiento, muchas de las personas que comiencen a recibir cuidados no serán “pacientes- sino miembros sanos, activos y productivos de la sociedad. Con el fin de expandir la escala de esta estructura, sería importante: (1) definir cuales individuos pueden ser atendidos dentro de un marco de entrega de servicios alternativo; (2) fortalecer los sistemas sanitarios que apoyan la descentralización, integración y delegación de funciones; (3) robustecer la cadena de proveedores; e (4) invertir en sistemas de datos para el seguimiento de pacientes y para la monitorización y evaluación de programas.

          Task shifting of antiretroviral treatment from doctors to primary-care nurses in South Africa (STRETCH): a pragmatic, parallel, cluster-randomised trial

          Summary Background Robust evidence of the effectiveness of task shifting of antiretroviral therapy (ART) from doctors to other health workers is scarce. We aimed to assess the effects on mortality, viral suppression, and other health outcomes and quality indicators of the Streamlining Tasks and Roles to Expand Treatment and Care for HIV (STRETCH) programme, which provides educational outreach training of nurses to initiate and represcribe ART, and to decentralise care. Methods We undertook a pragmatic, parallel, cluster-randomised trial in South Africa between Jan 28, 2008, and June 30, 2010. We randomly assigned 31 primary-care ART clinics to implement the STRETCH programme (intervention group) or to continue with standard care (control group). The ratio of randomisation depended on how many clinics were in each of nine strata. Two cohorts were enrolled: eligible patients in cohort 1 were adults (aged ≥16 years) with CD4 counts of 350 cells per μL or less who were not receiving ART; those in cohort 2 were adults who had already received ART for at least 6 months and were being treated at enrolment. The primary outcome in cohort 1 was time to death (superiority analysis). The primary outcome in cohort 2 was the proportion with undetectable viral loads (<400 copies per mL) 12 months after enrolment (equivalence analysis, prespecified difference <6%). Patients and clinicians could not be masked to group assignment. The interim analysis was blind, but data analysts were not masked after the database was locked for final analysis. Analyses were done by intention to treat. This trial is registered, number ISRCTN46836853. Findings 5390 patients in cohort 1 and 3029 in cohort 2 were in the intervention group, and 3862 in cohort 1 and 3202 in cohort 2 were in the control group. Median follow-up was 16·3 months (IQR 12·2–18·0) in cohort 1 and 18·0 months (18·0–18·0) in cohort 2. In cohort 1, 997 (20%) of 4943 patients analysed in the intervention group and 747 (19%) of 3862 in the control group with known vital status at the end of the trial had died. Time to death did not differ (hazard ratio [HR] 0·94, 95% CI 0·76–1·15). In a preplanned subgroup analysis of patients with baseline CD4 counts of 201–350 cells per μL, mortality was slightly lower in the intervention group than in the control group (0·73, 0·54–1.00; p=0·052), but it did not differ between groups in patients with baseline CD4 of 200 cells per μL or less (0·94, 0·76–1·15; p=0·577). In cohort 2, viral load suppression 12 months after enrolment was equivalent in intervention (2156 [71%] of 3029 patients) and control groups (2230 [70%] of 3202; risk difference 1·1%, 95% CI −2·4 to 4·6). Interpretation Expansion of primary-care nurses' roles to include ART initiation and represcription can be done safely, and improve health outcomes and quality of care, but might not reduce time to ART or mortality.

            Task-shifting of antiretroviral delivery from health care workers to persons living with HIV/AIDS: clinical outcomes of a community-based program in Kenya.

            To assess whether community-based care delivered by people living with HIV/AIDS (PLWAs) could replace clinic-based HIV care. Prospective cluster randomized controlled clinical trial. Villages surrounding 1 rural clinic in western Kenya. HIV-infected adults clinically stable on antiretroviral therapy (ART). The intervention group received monthly Personal Digital Assistant supported home assessments by PLWAs with clinic appointments every 3 months. The control group received standard of care monthly clinic visits. Viral load, CD4 count, Karnofsky score, stability of ART regimen, opportunistic infections, pregnancies, and number of clinic visits. After 1 year, there were no significant intervention-control differences with regard to detectable viral load, mean CD4 count, decline in Karnofsky score, change in ART regimen, new opportunistic infection, or pregnancy rate. Intervention patients made half as many clinic visits as did controls (P < 0.001). Community-based care by PLWAs resulted in similar clinical outcomes as usual care but with half the number of clinic visits. This pilot study suggests that task-shifting and mobile technologies can deliver safe and effective community-based care to PLWAs, expediting ART rollout and increasing access to treatment while expanding the capacity of health care institutions in resource-constrained environments.

              Community-supported models of care for people on HIV treatment in sub-Saharan Africa.

              Further scale-up of antiretroviral therapy (ART) to those in need while supporting the growing patient cohort on ART requires continuous adaptation of healthcare delivery models. We describe several approaches to manage stable patients on ART developed by Médecins Sans Frontières together with Ministries of Health in four countries in sub-Saharan Africa.
