Decreasing cost of public sector first-line ART services in India from 2007-2008 to 2015-2016.

ABSTRACT

INTRODUCTION: India has scaled-up antiretroviral treatment (ART) in public sector facilities, but data to understand time trends of average cost of ART are limited. MATERIALS AND METHODS: Cost and output data were collected at all public sector ART centres in undivided Andhra Pradesh (high-HIV burden state) and Rajasthan (low-HIV burden state) in India from fiscal year 2007-2008 to 2012-2013. Average cost per patient for first-line ART, and its relation with scale of services, were assessed. Using data on scale of services, the average cost was estimated up to 2015-2016. Break-even point was estimated from average and marginal cost functions. Costs were adjusted to 2015 constant price. RESULTS: The average cost per patient alive and on ART in 2015-2016 was US$162 in undivided Andhra Pradesh and US$186 in Rajasthan, which was 51.4% and 35.8% lower than in 2007-2008, respectively. Average ART drug cost declined by 27.2% during this period, and was 70.9% and 61.5% of the total ART cost in the two states in 2015-2016. The average cost other than ART drugs declined by 73.1% and 45.7%, with the number of patients served increasing 7 and 14.2 times, respectively. Average cost other than ART drugs had a significant negative relation with scale (R2 = 86.4%-82.8%, p<0.001). Break-even analysis suggested that 47.5% and 58.8% of the ART centres in undivided Andhra Pradesh and Rajasthan, respectively, were functioning below optimal scale in 2015-2016. The estimated total economic cost of first-line ART services provided in the public sector in India in fiscal year 2015-2016 was US$ 151 million; it would be US$ 216.1 million to provide this to all eligible persons in India. CONCLUSION: The average cost of providing first-line ART has declined in India, and further reduction is possible if the optimal scale of services is achieved. These findings can inform resource requirement for the ART programme in India.
