An optimization framework to determine an optimal local sharing variance for organ allocation
In this study, we focus on the analysis of sharing variances which allow allocating organs within participating members before offering them at other levels. This type of variance has been successfully implemented in the past. For example, Florida and Tennessee created the Statewide Sharing program whereby kidneys are made available within-state donor service areas before they are made available for regional or national allocation. This program removed geographic disparities within those two states and resulted in better performance of the system in the states. Given these success stories, we propose a multi-period optimiz...

A stochastic location model for designing primary healthcare networks integrated with workforce cross-training
Publication date: Available online 5 November 2019Source: Operations Research for Health CareAuthor(s): Amir Ahamdi-Javid, Nasrin RamsheAbstractHealth posts aim to elevate the level of public health by providing primary health services. The effectiveness of a health-post network depends on factors, such as the number and location of health posts. The service quality in such networks can be improved by controlling the amount of congestion at facilities. An important policy for decreasing operational cost of these networks is to consider a workforce mix of flexible and dedicated servers. This paper integrates the network des...

Understanding provider-level properties that influence the transmission of healthcare associated infections using network analysis
This study focused on Carbapenem-resistant Enterobacteriaceae (CRE) acquisition for patients who stayed in a long-term acute care hospital (LTACH) in central Virginia during July and August 2014. We used both patient data (e.g., bed movement, screening results for CRE) and provider activity data documented through the electronic medical record. We created a network of patients for each HCW and performed Poisson regression analysis including the network measures. A total of 204 providers saw at least one of the nine positive patients who stayed in the LTACH over the study period. From the Poisson regression, provider types,...

Using mixed integer programming and constraint programming for operating rooms scheduling with modified block strategy
This study aims to find the optimal sequence and schedule of patients by minimizing the cost of overtime, makespan and completion time of surgeons’ operations by considering the resource constraints. Considering the limitations and real conditions of Al-Zahra Hospital, the largest educational hospital in Isfahan, Iran, is also an aspect of this study. The problem is modeled by mixed integer programming and Constraint Programming (CP). The performance of the models is verified by several random test instances. The results indicate that CP is more efficient than mathematical modeling in terms of the computational time ...

Improving sustainability in a two-level pharmaceutical supply chain through Vendor-Managed Inventory system
This article aims to improve the sustainability of a pharmaceutical supply chain using a real case study. An analytical model is proposed to explore the effect of implementing a Vendor-Managed Inventory (VMI) system in minimizing the quantity of the expired medications at hospitals. Further, a set of Monte-Carlo simulation tests are conducted to investigate the robustness of the VMI model under demand uncertainty. Experimental results on a real case study under deterministic demand show the efficiency of the VMI model in eliminating the amount of expired medications without compromising customer’s satisfaction.

Needy boarding patients in emergency departments: An exploratory case study using discrete-event simulation
This article firstly explores the limited previous research on boarding patients. Secondly, this paper quantitatively demonstrates that needy boarding patients can significantly impact system performance and hence should be accounted for in the analysis and planning of an emergency department through discrete-event simulation. Next, three static priority policies (first-come, first-served and always prioritizing either boarding patients or the other patients) and one dynamic priority policy (using accumulating priorities) are evaluated on various performance measures. We find, for our case study, that system performance is...

A variability reduction method for the operating room scheduling problem under uncertainty using CVaR
The objective of the SMILP model is to minimize the CVaR of overtime and idle time costs. Numerical experiments are conducted on real-life benchmark instances, and showed that CVaR outperformed the widely used expected value (EV) approach in reducing variance of the total cost. As compared to the EV in terms of the total cost, the CVaR reduced the variance by 37%, produced a 25% lower interquartile range, and 24% lower median absolute deviation at a slight increase (4%) in the expected value.
