In Indonesia, primary health centres (PHCs) are mandated to provide essential medicines to ensure equal access to medication for all Indonesians, as stated in the national medicine policy. However, limited information is available regarding the actual practices of health workers within the context of decentralised governance. This paper investigates the discrepancies between national policies and local practices in two Indonesian districts, shedding light on coping mechanisms employed in each phase of medicine management within PHCs.

Background: Over the years, the knowledge translation (KT) field has moved from promoting linearized models to embracing the importance of interaction and learning. Likewise, there is now increased attention on the transfer of KT approaches to new environments. Some scholars, however, have warned that ideas about transferability still hinge on linear thinking and doing.

Background: At the onset of the COVID-19 pandemic, a local consortium in Uganda set up a telehealth approach that aimed to educate 3,500 Community Health Workers (CHW) in rural areas about COVID-19, help them identify, refer and care for potential COVID-19 cases, and support them in continuing their regular community health work. The aim of this study was to assess the functioning of the telehealth approach that was set up to support CHWs during the COVID-19 pandemic.

Methods: For this mixed-method study, we combined analysis of routine consultation data from the call-center, 24 interviews with key-informants and two surveys of 150 CHWs.

Knowledge translation platforms (KTPs) are seen as an important collaborative arrangement between researchers, policymakers, and practitioners. Yet, their 'sustainability' is a recurring issue. Several studies describe what makes KTPs sustainable, and focus on the role of institutional and contextual factors therein, yet few studies show how sustaining of KTPs is done in practice.

The World Health Organization and others warn that substandard and falsified medicines harm health and waste money, especially in low- and middle-income countries. However, no country has measured the market-wide extent of the problem, and no standardized methods exist to estimate the prevalence of either substandard or falsified medicines. This is, in part, because the task seems overwhelming; medicine markets are huge and diverse, and testing medicines is expensive.

Indonesia faces a growing informal sector in the wake of implementing a national social health insurance system-Jaminan Kesehatan Nasional (JKN)-that supersedes the vertical programmes historically tied to informal employment. Sustainably financing coverage for informal workers requires incentivising enrolment for those never insured and recovering enrolment among those who once paid but no longer do so. This study aims to assess the ability- and willingness-to-pay of informal sector workers who have stopped paying the JKN premium for at least six months, across districts of different fiscal capacity, and explore which factors shaped their willingness and ability to pay using qualitative interviews.

Introduction: Indonesia, the world's fourth most populous nation, is close to achieving universal health coverage (UHC). A widely-publicised falsified vaccine case in 2016, coupled with a significant financial deficit in the national insurance system, has contributed to concern that the rapid scale-up of UHC might undermine medicine quality. We investigated the political and economic factors that drive production and trade of poor-quality medicines in Indonesia.

Background: While leading AIDS organizations expect faith and health collaborations to play a crucial role in organizing and scaling up community-based HIV services, it is unclear how this can be realized. Little primary research has been conducted into which strategies for collaboration and service provision are most effective, efficient, scalable and sustainable. Seeking to align research with urgent needs, enhance coordination and increase the likelihood that results are used, this study aimed to set an inclusive global research agenda that reflects priority research questions from key stakeholders at the intersection of HIV healthcare and faith.

Background: In several countries, attempts are made to improve health promotion by centrally rating the effectiveness of health promotion interventions. The Dutch Effectiveness Rating System (ERS) for health promotion interventions is an improvement-oriented approach in which multi-disciplinary expert committees rate available health promotion interventions as 'theoretically sound', 'probably effective' or 'proven effective'. The aim of this study is to explore the functioning of the ERS and the perspective of researchers, policy-makers and practitioners regarding its contribution to improvement.
