Implementation of Aceh Health Insurance () 2013-2021: Has health equity been achieved for all Acehnese after armed conflict?

Aceh Health Insurance (-JKA) has been implemented since 2010 to increase the health equity by covering the health expenses and guaranteeing that all Acehnese are covered regardless of their economic, educational, and social statuses. However, since its implementation, there has been no study on its impact on health quality, particularly regarding the utilization of the main referral hospital (Dr Zainoel Abidin Hospital located in Banda Aceh) and the effects of the geographic accessibility and the number of specialist doctors in each regency/city on hospital utilization. This retrospective study assessed the equity factors during the Aceh Health Insurance implementation and during its integration to National Health Insurance (-JKN) from 2013 to 2021 using data of travel time (time spent for travelling from the origin regency/city of referred patients to the main referral center) and healthcare resources (number of specialist doctors).
