Introduction Lesotho, the country with the second‐highest HIV/AIDS prevalence (23.6%) in the world, has made considerable progress towards achieving the “95‐95‐95” UNAIDS targets, but recent success in improving treatment access to all known HIV positive individuals has severely strained existing healthcare infrastructure, financial and human resources. Lesotho also faces the challenge of a largely rural population who incur a significant time and financial burden to visit healthcare facilities. Using data from a cluster‐randomized non‐inferiority trial conducted between August 2017 and July 2019, we evaluated costs to providers and costs to patients of community‐based differentiated models of multi‐month delivery of antiretroviral therapy (ART) in Lesotho. Methods The trial of multi‐month dispensing compared 12‐month retention in care among three arms: conventional care, which required quarterly facility visits and ART dispensation (3MF); three‐month community adherence groups (CAGs) (3MC) and six‐month community ART distribution (6MCD). We first estimated the average total annual cost of providing HIV care and treatment followed by the total cost per patient retained 12 months after entry for each arm, using resource utilization data from the trial and local unit costs. We then estimated the average annual cost to patients in each arm with self‐reported questionnaire data. Results The average total annual cost of providing HIV care and treatment per patient was the highest in the 3MF arm ($122.28, standard deviation [SD] $23.91), followed by 3MC ($114.20, SD $23.03) and the 6MCD arm ($112.58, SD $21.44). Per patient retained in care, the average provider cost was $125.99 (SD $24.64) in the 3MF arm and 6% to 8% less for the other two arms ($118.38, SD $23.87 and $118.83, SD $22.63 for the 3MC and 6MCD respectively). There was a large reduction in patient costs for both differentiated service delivery arms: from $44.42 (SD $12.06) annually in the 3MF arm to $16.34 (SD $5.11) annually in the 3MC (63% reduction) and $18.77 (SD $8.31) annually in 6MCD arm (58% reduction). Conclusions Community‐based, multi‐month models of ART in Lesotho are likely to produce small cost savings to treatment providers and large savings to patients in Lesotho. Patient cost savings may support long‐term adherence and retention in care.

Background In the context of a move to universal health coverage, three separate systematic reviews were conducted to summarise available evidence on the direct costs of interventions for type 2 diabetes mellitus, hypertension, and cardiovascular disease in South Africa. Methods PubMed® and Web of Science was searched for literature published between 01 and 1995 and 27 October 2022. Additionally, reference and citations lists of retrieved articles and experts were consulted. We also tracked reference lists of previous, related systematic reviews. Eligible publications were cost analyses of clinical interventions targeted at adults age 15 + reporting primary estimates of in- and out-of-hospital costs from a provider perspective. Costs were extracted and converted to 2021 US dollars, and article methodological and reporting quality was appraised using the 2013 CHEERS checklist. Results Of the 600, 1,172 and 1,466 identified publications for type 2 diabetes mellitus, hypertension, and cardiovascular disease, respectively, 10, 12, and 17 met full inclusion criteria. 60% of articles reported cardiovascular disease costs, 52% were of good reporting quality, and 10%, 50%, and 39% of type 2 diabetes mellitus, hypertension and cardiovascular disease papers reported private-sector costs only. Hypertension drug costs ranged from $2 to $85 per person-month, while type 2 diabetes mellitus drug costs ranged between $57 and $630 per person-year (ppy). Diabetes-related complication treatment costs ranged from $55 for retinopathy treatment to $25,193 ppy for haemodialysis, while cardiovascular disease treatment costs were between $160 and $37,491 ppy. Drugs and treatment of complications were major cost drivers for hypertension and type 2 diabetes mellitus, while hospitalisation drove cardiovascular disease costs. Conclusion The intervention costs of type 2 diabetes mellitus, hypertension and cardiovascular disease care have received more attention recently, particularly diabetes-related complications and cardiovascular disease. However, 39% of identified cardiovascular disease treatment costs used a private sector perspective, leaving significant research gaps in the public sector and the cheaper to treat hypertension and type 2 diabetes mellitus. This review fills an information gap regarding the intervention costs of these diseases in South Africa.

Background In the context of a move to universal health coverage, three separate but connected systematic reviews were conducted to summarise available evidence on the direct costs of interventions for type 2 diabetes mellitus, hypertension, and cardiovascular disease in South Africa. Methods PubMed® was searched for literature published between 01 January 1995 and 30 November 2021. Additionally, reference and citations lists of retrieved articles and systematic reviews were reviewed, and experts were consulted. Eligible publications were cost analyses of clinical interventions targeted at adults age 15 + reporting primary estimates of in- and out-of-hospital costs from a provider perspective. Costs were extracted and converted to 2021 US dollars, and article methodological and reporting quality was appraised using the 2013 CHEERS checklist. Results Of the 248, 650 and 968 identified publications for type 2 diabetes mellitus, hypertension, and cardiovascular disease, respectively, 10, 12, and 18 met full inclusion criteria. 60% of articles reported cardiovascular disease costs, 50% were of good reporting quality, and 10%, 50%, and 39% of type 2 diabetes mellitus, hypertension and cardiovascular disease papers reported private-sector costs only. Hypertension drug costs ranged from $2 to $85 per person-month, while type 2 diabetes mellitus drug costs ranged between $57 and $630 per person-year (ppy). Diabetes-related complication treatment costs ranged from $55 for retinopathy treatment to $25,193 ppy for haemodialysis, while cardiovascular disease treatment costs were between $160 and $37,491 ppy. Drugs and treatment of complications were major cost drivers for hypertension and type 2 diabetes mellitus, while hospitalisation drove cardiovascular disease costs. Conclusions The economic impact of type 2 diabetes mellitus, hypertension and cardiovascular disease care has received more attention recently, particularly diabetes-related complications and cardiovascular disease. However, 39% of identified cardiovascular disease treatment costs used a private sector perspective, leaving significant research gaps in the public sector and the cheaper to treat hypertension and type 2 diabetes mellitus. This review provides an insightful, though incomplete, picture of the economic burden of these diseases in South Africa.
