Operating room scheduling is an important operational problem in most hospitals. In this paper, a novel mixed integer programming MIP model is presented for minimizing Cmax and operating room idle times in hospitals. Using this model, we can determine the allocation of resources including operating rooms, surgeons, and assistant surgeons to surgeries, moreover the sequence of surgeries within o...

We propose an extension of the PAS problem described in our previous work [6], which considers also constraints about the utilisation of operating rooms for patients that have to undergo a surgery. We design a solution approach based on local search, which explores the search space using complex neighbourhood operators.

This paper addresses the problem of operating room (OR) scheduling at the tactical level of hospital planning and control. Hospitals repetitively construct operating room schedules, which is a time consuming, tedious and complex task. The stochasticity of the durations of surgical procedures complicates the construction of operating room schedules. In addition, unbalanced scheduling of the oper...

conclusions the world health organization (who) has suggested relatively relaxed limits of 100 cfu/m3 for bacteria and 50 cfu/m3 for fungi in the hospital air. therefore, quantitative and qualitative outcomes of this study demonstrate that contamination level and bacterial variety in surgery rooms and emergency departments is high and effective measures must be taken to control the possible hea...

background: nursing project management is widely used in different aspects of the society. however, whether the nursing project management can control the infections in the operation room (or) is rarely reported. we evaluated the outcomes of surgical patients after implementing a nursing project management program to provide new scientific ways to manage the or infections. methods: overall, 382...

background and purpose: upon centuries, wars have taken over countries due to theadvancement of sophisticated warfare,causingserious injuries among soldiers. nurses are directly involved in preoperative and postsurgical patient care. one of the most remarkable contributions of the iranian operating room nurses was to provide medical care for wounded soldiers in field hospitals during the iran-i...

A s revenues have decreased, health care systems have instituted intensive cost reduction programs, such as the use of pharmaceutical practice guidelines, to attempt to maintain profitability. After implementing such initiatives, some health care systems are having difficulty in further decreasing costs without sacrificing customer (patient) service. The next generation of process improvement e...

Abstract One of the critical issues in healthcare management is operating room (OR) scheduling problem. Solutions to this problem consider surgery durations and allocate elective surgeries OR sessions order create surgical lists high quality. Determining quality a list key undertaking within focus research. Currently, probability- and/or expectation-based measures are used instead statistical d...
