No. 0070482 A Stochastic Overbooking Model for Outpatient Clinical Scheduling with No-Shows Kumar Muthuraman, Mark Lawley School of Industrial Engineering, School of Biomedical Engineering, Purdue University, West Lafayette, IN 47906 [email protected], (765) 494-5416, [email protected], (765) 494-5415 POMS 18th Annual Conference Dallas, Texas, U.S.A., May 4 to May 7, 2007 We formulate a stochastic overbooking model and develop an appointment scheduling policy for outpatient clinics. The schedule is constructed for a single service period partitioned into time slots of equal length. A clinic scheduler assigns patients to slots through a sequential patient call-in process where the scheduler must provide each calling patient with an appointment time before the patient’s call terminates. Each calling patient has a no-show probability, and overbooking is used to compensate for patient no-shows. The scheduling objective captures patient waiting time, staff overtime, and patient revenue. We derive conditions under which the objective evolution is unimodal and investigate the behavior of the scheduling policy under a variety of conditions.

An Appointment Order Outpatient Scheduling System That Improves Outpatient Experience
Patient wait time and access to care have long been a recognized problem in modern outpatient healthcare delivery systems. Despite all the efforts to develop appointment rules and policies, the problem of long patient waits persists. Regardless of the reasons, the fact remains that there are few implemented models for effective scheduling that consider patient wait times, physician idle time, o...

BACKGROUND Patient no-shows in outpatient delivery systems remain problematic. The negative impacts include underutilized medical resources, increased healthcare costs, decreased access to care, and reduced clinic efficiency and provider productivity. OBJECTIVE To develop an evidence-based predictive model for patient no-shows, and thus improve overbooking approaches in outpatient settings to...
متن کاملA Stochastic Model for Prioritized Outpatient Scheduling in a Radiology Center
This paper discussed the scheduling problem of outpatients in a radiology center with an emphasis on priority. To more compatibility to real-world conditions, we assume that the elapsed times in different stages to be uncertain that follow from the specific distribution function. The objective is to minimize outpatients’ total spent time in a radiology center. The problem is formulated as a fle...

Background and Objectives: Operating rooms (ORs) are precious resources in hospitals, as they constitute more than 40% of the hospital revenues.As such, surgical cancellations are very costly to hospitals. Same-day surgery cancellations or no-shows were found to be the main contributing factor to underutilization of operating rooms (ORs) in a public-sector hospital despite the ...
