<![CDATA[Background: Interprofessional collaboration (IPC) is critical for delivering comprehensive and coordinated care, particularly in managing complex noncommunicable diseases (NCDs). However, in primary care settings, collaboration among healthcare professionals remains fragmented. Evidence on how different health professions collaborate in community health centers (CHCs) remains limited. This knowledge gap hampers efforts to strengthen team-based NCD management in primary care.Purpose: This study aimed to assess IPC among healthcare professionals in primary care and identify domains that require strengthening for NCD management.Methods: A cross-sectional study was conducted in 37 CHCs in Palembang City, South Sumatra Province, Indonesia. A total of 301 healthcare professionals, including nurses, medical doctors, midwives, and public health workers, were selected through simple random sampling. Data were collected using a sociodemographic questionnaire and the validated Indonesian version of the Collaborative Practice Assessment Tool (CPAT), which consists of 56 items across eight subscales. Descriptive statistics and Kruskal–Wallis tests were used to analyze the data.Results: A total of 301 healthcare professionals participated. Overall CPAT scores were relatively similar across professions, with median (IQR) values of 292 (275.75–330.50) for nurses, 304 (278–329.50) for medical doctors, 292 (278.50–334) for midwives, and 287 (279–314) for public health workers. The highest scores across professions were observed for general role responsibilities and autonomy and team leadership, while the lowest scores were observed for community linkages and coordination of care and patient involvement. Only the communication and information exchange domain showed a significant difference among professions (p = .039).Conclusion: IPC for NCD management in primary care demonstrated strengths in role clarity, autonomy, and team leadership but remained weak in communication, patient involvement, and community linkages. Targeted interventions, including structured interprofessional education, patient-centered care approaches, and stronger community partnerships, are needed to strengthen collaboration. ]]>
