Abstract

Each year over 800,000 adults with chronic obstructive pulmonary disease (COPD) are admitted to U.S. hospitals. Because low oxygen affects most organ systems, they could be treated for any of several different illnesses. However, that treatment typically involves inhaled medications administered three or four times per day according to a common, hospital-wide medication schedule. Administered by a respiratory care practitioner (RCP) assigned to the unit where the patient is located, each treatment takes about 20 minutes. Unfortunately, lengthy administration times and common medication schedules interact to create significant workload peaks for RCPs, causing a large fraction of the scheduled medications to be administered late. This contributes to lengthier hospital stays and other undesirable outcomes.

RCP workload peaks can be attenuated by assigning different scheduled medication times to each care unit. However, this strategy does little to improve on-time performance if individual RCPs only treat the patients in one or two care units. We propose un-tethering RCPs from their traditional unit assignments, allowing them to move together as a team from care unit to care unit administering inhaled medications. Combined with staggered medication schedules, this “swarm” strategy can dramatically reduce late medication errors. Perhaps more importantly, swarm staffing enables a primary care relationship between RCPs and their chronic patients; a key element of an effective chronic care model. This research characterizes the late medication problem, presents stochastic models to select and assess alternative staggered medication schedules, and reports the experience of one hospital that adopted this strategy.

Topic: Information Effects on Performance of Two-tier Service Systems with Strategic Customers

Abstract: This paper considers a two-tier service system with one free service channel and one toll service channel. While the free system offers free service with a long waiting time, the toll service system offers paid service with a guaranteed maximum expected waiting time at a price. This kind of service system can be found in many public service situations. For example, for a certain type of non-emergency surgery, the free system may represent the public hospital service covered by the government medical insurance plan and accessed by all patients and the toll system may represent the private hospital service with limited number of patients admitted at any point in time. We study the information effects on the performance of such a two-tier service system with strategic customers. First we find that providing real-time delay information to customers can significantly improve the performances of both toll and free systems. Furthermore, we show that the system performance characteristics remain similar for both with real-time and without real-time delay information scenarios. The implication of this observation is that a system with real-time delay information can be approximately analyzed by a model without real-time delay information. We also investigate the effects of the pricing and service guarantee on the performance of the two-tier service system and reveal that there is an inconsistency between the toll system's profit goal and the customer service goal of the public service. *This is a joint work with Hsing Paul Luh
