Patient referral in primary health care: A scoping review of Malaysian publications

ABSTRACT

Introduction: An effective referral system is essential for optimising resource use and improving patient outcomes. In Malaysia, local referral publications have not been comprehensively reviewed. This scoping review maps the current Malaysian literature on the referral process between primary and secondary/tertiary care.
Methods: We searched bibliographic databases using terms related to patient referral, primary health care and Malaysia. Additional sources included guidelines, conference abstracts and reference lists of included articles. All Malaysian publications that discussed referral rates, criteria, processes, barriers or referral-related interventions were eligible.
Results: Ninety-two publications were included: 68 were reviews or guidelines, and 24 were original research articles. Most guidelines had specific sections on referral criteria but lacked referencing of local research to support their recommendations. Most original research (n=19) examined referral from primary care perspectives, while only five focused on secondary/tertiary care perspectives. The reported referral rates ranged from 1.76% in public clinics to 1.8%–2.4% in private general practice. The key themes identified included appropriateness of referral, reasons for referral, barriers to referral and interventions to improve referral quality. The evidence gaps included limited real-world evaluation of referral pathways and lack of private-sector studies, indicating insufficient Malaysian data to develop national guidelines regarding patient referral.
Conclusion: Malaysian evidence on patient referral remains limited but highlights important issues including appropriateness, communication gaps and systemic barriers. Strengthening primary–secondary care linkages, adopting electronic referral systems and evaluating specific referral interventions are potential strategies to optimise resource allocation and support the development of standardised referral guidelines.
