Cost of a diagonal sexual and reproductive health package to enhance reproductive health among female sex workers in Durban, South Africa

Abstract

Background and objectives: In response to HIV epidemic in Sub- Saharan Africa, there has been widespread concern about the structure and delivery of Sexual Reproductive Health (SRH) and HIV services to improve outcomes among high-risk groups, including sex workers. The ‘Diagonal Interventions to Fast-Forward Enhanced Reproductive health’ (DIFFER) project was conceptualised based on the hypothesis that integrating vertical SRH interventions targeted to FSW, with horizontal health systems strengthening, is likely to be more effective and cost-effective than current practice. The aim of the study was to measure the cost of designing and delivering a SRH package for female sex workers in Durban, South Africa, as part of the DIFFER project. / Methods: We measured the total and incremental costs of the DIFFER intervention package in Durban from a provider perspective, using a combination of ingredients and activity based costing approaches. An excel-based data capture tool was developed to collect the intervention package cost data. The intervention costs were collected prospectively from the project accounts of the implementing agencies and costs to the public health providers were collected via key informant interviews using a cost data capture form and subsequently entered into the spreadsheet. The total and average annual costs, as well as total and average annual costs per sex worker covered were estimated. All costs were adjusted for inflation, discounted and converted to 2016 International dollar. / Results: Total and average annual program costs of implementing the DIFFER intervention in Durban were INT$411,239 (INT$ 428,461, including services provided to the general population) and INT$256,594 (INT$ 273,816, including services provided to the general population) respectively. The total cost and average annual cost per sex worker covered were INT$117 and INT$ 73 respectively. Staff costs accounted for the largest proportion of the intervention cost, comprising more than 80% of the total cost, following by material and supplies, accounting for 10% of costs. / Conclusion: The DIFFER intervention package in Durban is a low cost intervention and likely to be cost-effective and sustainable. The intervention can be considered for replication and scale-up in South Africa and similar settings elsewhere
