摘要：We develop a finite-horizon discrete-time constrained Markov decision process (MDP) to model diagnostic decisions after mammography where we maximize the total expected quality-adjusted life years (QALYs) of a patient under resource constraints. We use clinical data to estimate the parameters of the MDP model and solve it as a mixed-integer program. By repeating optimization for a sequence of budget levels, we calculate incremental cost-effectiveness ratios attributable to consecutive levels o...

摘要：Free-for-service (FFS) contracts, first introduced in 2004, dramatically changed the way the pharmaceutical distribution supply chains are designed, managed, and operated. Investment buying (IB), forward buying in anticipation of drug price increases, used to be the way the distributors made most of their profits. FFS contracts limit the amount of inventory distributors can carry at any time (by imposing an inventory cap) and require inventory information sharing from the distributors to the m...

摘要：There is now a broad consensus among healthcare professionals that the U.S. healthcare delivery system is woefully inefficient and needs to be radically redesigned. Healthcare costs have always been a driving force in policy and management, but quality has become equally important in driving decisions, particularly since emerging payment systems include metrics on clinical and operational performance. With the increasing use of information technology to capture financial, operational, and clin...

摘要：This series of discussions presents commentaries on where the field of healthcare operations management is now and possible future research directions, expanding upon the key points raised by Green [Green LV (2012) The vital role of operations analysis in improving healthcare delivery. Manufacturing Service Oper. Management 14(4):488-494].

摘要：We study the impact of physician workload on hospital reimbursement utilizing a detailed data set from the trauma department of a major urban hospital. We find that the proportion of patients assigned a high-severity status for reimbursement purposes, which maps, on average, to a 47.8% higher payment for the hospital, is substantially reduced as the workload of the discharging physician increases. This effect persists after we control for a number of systematic differences in patient character...

摘要：This research investigates the effect of process management on clinical and experiential quality. Clinical quality measures hospitals' performance on patient safety, i.e., adherence to standards, whereas experiential quality relates to patient centeredness, i.e., responsiveness to the needs and preferences of the patient. Drawing from the organizational learning literature, we argue for a trade-off between clinical and experiential quality as hospitals emphasize process management. We also stu...

摘要：One key driver of improvement in surgical outcomes is a surgeon's prior experience. However, research notes that not all experience provides equal value for performance. How, then, should surgeons accumulate experience to improve quality outcomes? In this paper, we investigate the differential effects of focal and related (i.e., tasks similar to, but not identical to, the focal task) experience. We open up the black box of the volume-outcome relationship by going beyond just dividing experienc...

摘要：In recent years, the performance-based approach to contracting for medical services has been gaining popularity across different healthcare delivery systems, both in the United States (under the name of pay for performance) and abroad (payment by results in the United Kingdom). The goal of our research is to build a unified performance-based contracting (PBC) framework that incorporates patient access-to-care requirements and that explicitly accounts for the complex outpatient care dynamics fa...
