Challenges in delivering healthcare services among immigrants from Southeast Asia: A scoping review

Cross-border migration presents increasing challenges to healthcare systems globally. Ensuring equitable healthcare access for immigrant populations, particularly in Southeast Asia, requires a thorough understanding of the barriers to effective service delivery. This scoping review aimed to synthesize the existing literature on the challenges related to the delivery of healthcare services to immigrant communities from Southeast Asia. While previous studies (e.g., Brandenberger et al., 2019) applied the 3C framework to migrants and refugees globally, this review generates new insights by focusing specifically on Southeast Asia, a region underrepresented in the literature. By applying the 3C model in this context, our review identifies region-specific challenges, such as immigration policies, financial barriers, and COVID-19 impacts, that extend beyond the findings of earlier global reviews.

A comprehensive search was conducted in ProQuest, PubMed, ScienceDirect, and Scopus databases on October 13, 2024, for studies published between January 1, 2011, and October 13, 2024. The search strategy used tailored keywords, including "challenges," "healthcare services," "immigrants," and "Asia." Inclusion criteria focused on peer-reviewed, English-language articles reporting on challenges in healthcare service delivery among immigrant populations in Southeast Asia. Data extraction and synthesis were guided by the 3C model: communication, continuation of care, and confidence in the healthcare system.

The search identified 656 records, of which 7 studies met the inclusion criteria after a multi-stage screening process. Key challenges identified across the included studies were: Communication barriers, including language differences, cultural misunderstandings, and limited health literacy; Issues with continuation of care, such as poor health literacy, difficulties navigating healthcare systems, barriers to accessing services (e.g., due to legal status or financial constraints), and lack of coordination between healthcare and social services; and Lack of confidence in the healthcare system, stemming from distrust, lack of understanding, and negative experiences, including perceived discrimination.

This review highlights the complex challenges in delivering healthcare services to immigrants from Southeast Asia. These challenges, encompassing communication, continuation of care, and confidence, necessitate targeted and multifaceted interventions. Addressing these issues through culturally competent care, enhanced communication strategies, and policy reforms that promote equitable access is crucial for improving the health and well-being of immigrant populations and fostering more inclusive healthcare systems within the region.
