Bridging Policy and Service Performance of Hospital-Based Nutrition Support by Healthcare Information Technology.

Although the healthcare policy was implemented to incentivize the multidisciplinary services of hospital-based nutrition support team (NST) in South Korea, timely completion of the services has been challenging in the hospitals. We enhanced NST healthcare information technology (NST-HIT) to bridge the gap between policy implementation and seamless execution of the policy in the hospital system. A 48 month pre-test-post-test study was performed, including a 12 month pre-intervention period, a six month intervention period, and a 30 month post-intervention period. The enhanced NST-HIT provided sufficient patient data and streamlined communication processes among end-users. A Student's t-test showed that the timely completion rate of NST consultations, the reimbursement rate of NST consultations, average response times of NST physicians and nurses, and length of hospital stay significantly improved during the post-intervention period. A segmented regression analysis of interrupted time series showed that the average response times of NST physicians had sustained after the interventions. We believe that well-structured, multi-pronged initiatives with leadership support from the hospital improved service performance of hospital NST in response to national-level healthcare policy changes.
