Abstract: OBJECTIVES: In remote Australian First Nations communities, the burden of curable sexually transmitted infections (STIs) is highest for young women and men aged 16-29 years and for women is associated with two-fold higher rates of hospitalisations for pelvic inflammatory disease (PID) than for non-First Nations women. Following a randomised trial, decentralised community-led molecular point-of-care (POC) testing for STIs has operated in remote primary care across Australia for more than 7 years, improving uptake and timeliness of treatment for chlamydia, gonorrhoea and trichomonas infections. However, cost-effectiveness remains unknown. METHODS: A decision analytic model was devised to compare costs and outcomes associated with a POC testing programme for chlamydia, gonorrhoea and trichomonas infections in women and men aged 16-29 years seeking care, compared with standard care (laboratory-based testing). The analysis used a government payer perspective and 10-year time horizon. The primary outcome was the cost ($A) per quality-adjusted life year (QALY) gained. Sensitivity analyses examined uncertainty around the results. RESULTS: Based on a combined testing positivity rate of 36% and 29% for chlamydia, gonorrhoea and trichomonas for women and men, respectively, the POC testing programme, compared with laboratory testing, produced an estimated incremental cost per QALY ratio (ICER) of $A19 714 (95% CIs $A19 608 to $A19 821) over 10 years. Among those with an STI, the POC testing programme was predicted to reduce diagnosed PID by 30% and preterm/low birth weight babies by 17%. Sensitivity analyses indicated that the ICER was most sensitive to the probability of infection and receiving treatment within 2 days, based on a willingness-to-pay threshold of $A50 000. CONCLUSION: This health economic evaluation indicates that a scaled molecular POC testing programme for the management of STIs in remote primary care settings is cost-effective compared with standard care. Sustained POC testing in this setting is likely to improve reproductive health outcomes.
