Helping the captive audience: advance notice of diagnostic service for hospital inpatients

Nan Liu1, Miao Bai2, Zheng Zhang3

Problem: Inpatients wait for hospital diagnostic services, causing chaos. Methodology: We propose "advance notice" scheduling, providing patients with preparation and service time windows. Markov Decision Process optimizes decisions. Numerical study shows significant operational improvement. Managerial implications: Advance notice policy reduces waiting and improves appointment-based services.

Problem: Evaluating an ED delay announcement system in Hong Kong's healthcare. Methodology: Studying 1.3M patient visits, we estimate patient sensitivity to announced waiting times (WT) and factors influencing it. Results show potential improvements in reducing WT and patients leaving without being seen. Implications: Increase patient awareness, reduce WT update window, focus on older population and Kowloon district for promotion.



The impact of hospital and patient characteristics on psychiatry readmissions

We study hospitals' operational characteristics contributing to the re-admission of psychiatry patients. We propose that length of stay (LOS) mediates the effects of hospital characteristics on the risk of readmission. We reveal how patient characteristics moderate these effects. Using a dataset of 15,000 psychiatry patients, we provide evidence on the negative volume-outcome and nonlinear LOS-outcome relationship. Our analysis provides helpful insights for managing the flow of psychiatric patients.
