Thailand s key population led health services KPLHS are a hallmark of the success of the country s HIV response In Thailand KPLHS refer to a defined set of HIV related health services for key populations designed and delivered by trained and qualified lay providers who are often members of key populations These services are needs based demand driven and client centered and include HIV testing pre exposure prophylaxis PrEP services and linkage to HIV care KPLHS augments the national program in Thailand by bridging the gap between government services and key populations especially for the most marginalized communities Currently more than half of all Thai PrEP users access PrEP through KPLHS In the first half of 2019 COVID 19 impacted the delivery of and access to KPLHS and other HIV services in Thailand For example numbers of HIV and STI testing clients in major HIV STI centers declined by 50 75 there were reductions in numbers of new HIV diagnoses and treatment initiations there was uncertainty around the supply of PrEP travel restrictions prevented some clients from visiting their usual providers and there were personal protective equipment shortages PrEP Xpress delivery service Mplus Foundation Chiang Mai The Institute of HIV Research and Innovation IHRI supported KPLHS to adapt PrEP services and implement a range of innovations at the community level These included extending PrEP prescriptions from 3 to 6 months for many clients continuing PrEPtelehealth consultations to minimize clinic visits and allow those under movement or travel restrictions to continue to access PrEP care Xpress delivery services for medicationSTI self sampling and PrEP effective use counseling was introduced allowing MSM clients to choose to stop re start and tailor daily or event driven use to their HIV risk Self sampling Tangerine Clinic IHRI As KP lay providers in community based clinics were not prioritized during personal protective equipment shortages KPLHS made improvised plastic shields and other protective equipment to help protect themselves and their clients Improvised PPE to protect clients and their providers at the MPLUS clinic Mplus Foundation Chiang Mai Outside the clinic KPLHS also helped ensure that client s essential life needs were met during the pandemic including food packages daily necessities temporary housing shelter emergency funds and live saving guides and toolkits for those practicing sex work Food deliveries to vulnerable clients SWING Foundation These service adaptations have helped overcome some of the barriers to PrEP services for key populations during the COVID 19 pandemic The adaptations are largely sustainable have helped expand the differentiated service delivery model for PrEP and are becoming popular options for clients Indeed STI self sampling has increased in popularity with rates of acceptance increasing from 48 in May 2020 to 78 in July 2020 KPLHS and other HIV services should embed adaptations that improve accessibility availability quality and acceptability including those introduced in response to the COVID 19 pandemic to improve PrEP services post COVID 19 The adaptations introduced by KPLHS in Thailand and their successes provide important lessons for other countries and HIV services
