Programmes for the prevention of mother-to-child HIV infection transmission have made progress in Yunnan Province, China, from 2006 to 2015: a cost effective and cost-benefit evaluation.

BACKGROUND

Prevention of mother-to-child transmission (PMTCT) of HIV programmes have substantially reduced HIV infections among infants in Yunnan Province, China. We conducted a macro-level economic evaluation of Yunnan's PMTCT programmes over the 10 years from 2006 to 2015 from a policymaker perspective.

METHODS

The study methodology was in accordance with the guidelines from the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement. We quantified the output from the Yunnan's PMTCT programmes by estimating the number of paediatric HIV infections averted and the relative savings to both the health care system and society. The return-on-investment ratio (ROI) was calculated as the output (numerator) divided by the input (denominator).

RESULTS

We have found that the US$ 49 million investment in Yunnan's PMTCT programmes over the period from 2006 to 2015 averted an estimated 2725 new paediatric HIV infections and resulted in an estimated 134,008 QALY acquired. It saved an estimated US$ 0.5 billion in treatment expenditures for Yunnan's healthcare system and nearly US$ 3.9 billion in productivity. The ROI was 88.4, meaning every US$ 1 invested brought about US$ 88.4 in benefits.

CONCLUSIONS

Our results support the ongoing investment in PMTCT programmes in Yunnan Province. The PMTCT strategy is a cost effective and cost-benefit strategy in the periods from 2006 to 2015. Despite higher investments in the future, the overall investment in the PMTCT programmes in Yunnan province could be offset by averting more paediatric infections.
