Hospital nutrition services are an important component of healthcare systems because they contribute directly to patients’ nutritional fulfillment, recovery processes, patient safety, and healthcare quality improvement. Inadequate nutrition management may increase the risk of malnutrition, prolong hospitalization, and reduce the effectiveness of medical treatment. Therefore, this study aimed to analyze the implementation of inpatient nutrition service management at Rumah Sakit Islam Karawang, particularly regarding nutrition planning, food processing, and meal distribution systems. This research employed a descriptive qualitative design to obtain a comprehensive understanding of inpatient nutrition service implementation within the hospital setting. Data were collected through observations, documentation, and literature review, while data analysis was conducted using descriptive qualitative analysis involving data reduction, presentation, interpretation, and conclusion drawing. The findings revealed that inpatient nutrition service management at Rumah Sakit Islam Karawang has been implemented systematically through integrated menu planning systems, individualized dietary determination based on patients’ clinical conditions, standardized food processing procedures, and scheduled meal distribution practices. The hospital applies a seven-day menu cycle system and maintains hygiene, sanitation, and food safety standards during food preparation and distribution activities. In addition, timely meal distribution and dietary accuracy support patient nutritional fulfillment and contribute to healthcare service quality improvement. This study implies that effective nutrition service management systems can strengthen patient-centered healthcare services, improve patient satisfaction, support recovery processes, and enhance hospital operational quality. The originality of this study lies in its comprehensive analysis of inpatient nutrition service management by integrating nutrition planning, food processing, and meal distribution systems within a single hospital context, whereas previous studies generally focused only on specific aspects such as dietary accuracy, food distribution, or patient satisfaction. Therefore, this study provides additional empirical insights into hospital nutrition service management and contributes to the development of healthcare quality improvement strategies in hospital settings.
