We are interested in reducing the waiting time of the patients and in increasing the utilization of the operating rooms (OR). The sum of the overtime of the staff and the time where the ORs are not utilized for surgeries are used as a surrogate measure for OR utilization. A Non-Dominated Sorting Genetic Algorithm II (NSGA-II) that uses a random key representation for the schedules is proposed to solve heuristically this scheduling problem. The NSGA-II approach is hybridized with a local search approach. Discrete-event simulation is used to assess the fitness of the chromosomes within each generation of the NSGA-II approach taking into account the expected availability of surgeons, anesthesia doctors, nurses, stochastic surgery durations, and preferences of the patients with respect to the point of time of the surgery. The simulation model is described in detail and used to study the impact of stochastic arrival patterns of the patients and stochastic surgery durations on the performance of the executed schedules. Rescheduling strategies are investigated in different situations. We present the results of computational experiments using data from an actual eye hospital. These results clearly demonstrate that schedules obtained by dispatching rules and manually by the medical staff are outperformed by the proposed NSGA-II approach. Finally, a successful real-world implementation of the scheduling heuristic is briefly discussed.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"4 1","pages":"191 - 208"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2014.965395","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Homecare services are aimed at providing medical, paramedical, and social aid to patients at their own homes, leading to reduced hospitalization and healthcare operations costs in the medium to long term. However, the home healthcare worker scheduling problem is a complex one since it combines the hard vehicle routing and the staff assignment problems. As such, the purpose of this research is to present a fuzzy simulated evolution algorithm, based on fuzzy evaluation techniques, to address the homecare worker scheduling problem in a home care environment. The main objective is to decide on (i) which patients to assign to each worker, and (ii) the best route or trip for each care giver to execute the healthcare tasks so as to satisfy the patient's preferences in the time window during which the care giver should visit and offer the requested healthcare service. Computational results on illustrative experiments show that the proposed algorithm is a promising decision support tool.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"4 1","pages":"209 - 216"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2014.966213","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the amount of leukocyte in a unit of the blood is a critical issue in the blood transfusion process and patient safety, estimating and monitoring the capability of the leukocyte filtering process to meet the target window is very important for blood service sectors. However, observed data from the leukocyte filtering process show that the leukocyte levels after filtering demonstrate a right skewed distribution and applying conventional methods with a normality assumption fails to provide trustful results. Hence, we first conduct a simulation study to compare different methods in estimating the process capability index of non-normal processes and then we apply these techniques to obtain the process capability of the leukocyte filtering process. The study reveals that the Box-Cox transformation method provides reliable estimation of the process capability of the leukocyte filtering process.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"4 1","pages":"167 - 177"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2014.965393","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper traces the evolution of Industrial Engineering in healthcare from its beginning through the present with an emphasis on the period ending 1989. It discusses the hospital roots of the profession that began with emulating the use of IE in manufacturing (hospital management engineering) and how it has come to embrace various dimensions of healthcare as Health Systems Engineering (HSE). The paper's objective is to provide the background of HSE which includes discussions of the environmental, governmental, and healthcare industry factors that were and remain the impetus for growth of the profession; the various ways by which a healthcare organization can avail itself of securing Health Systems Engineering capabilities; the past and current ways by which practitioners enter the HSE field; the professional organizations to provide easy networking, career development, professional recognition opportunities, and advocacy for the profession; etc.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"4 1","pages":"217 - 229"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2014.966214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60566109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radio frequency identification (RFID) technology has been found to be one way to potentially alleviate this problem by improving process efficiency and reducing costs. However, return on investment (ROI) in RFID technology and its impact are based on the specifics for each healthcare organization and there is no standard methodology. Therefore, a methodology for ROI was created and a case study in a 600-bed hospital was undertaken to determine the feasibility of RFID implementation and its potential impact on asset management. The variables used in the ROI computational methodology were clinical and biomedical asset searching time, shrinkage rates, utilization rates and RFID implementation costs. Specific mobile assets that would benefit most from RFID technology were then selected within these variables. Under the assumptions from past studies, this work determined that implementing RFID technology within the 600-bed hospital was a financially viable decision with a 10.2-month payback period of the initial investment costs, and an expected 327% ROI within three years. This study highlights important RFID asset management techniques and characteristics for hospitals to consider as they determine their own financial feasibility with regards to RFID implementation. The approach can be used to inform budget planning in institutions for RFID implementation.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"4 1","pages":"144 - 155"},"PeriodicalIF":0.0,"publicationDate":"2014-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2014.938207","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do this effectively, care must be coordinated across several types of specialists, and potentially across multiple settings. In this paper, we develop a Patient-Centered Surgical Home (PCSH) for outpatient surgery based on the concept of the Perioperative Surgical Home proposed by the American Society of Anesthesiologists. A key feature of the PCSH is to have an anesthesiology preoperative assessment clinic (APC) serve as system coordinator and information integrator. Based on a study of outpatient surgery at the University of Texas Health Science Center at San Antonio and its primary teaching hospital using statistical analysis and simulation, we demonstrate how this can be accomplished. We show that for the PCSH to succeed, APC must see the right patients with the right information by overcoming improper triaging of patients and patient information deficiencies. Our analysis shows that with the proper screening tool and modifications to the way triage is handled, it is possible to increase the number of patients that the APC sees each day with a modest increase in resources. Much of the potential benefits rest on the cooperation of the referring clinics as well as closing the gap between the current level of patient information and what is needed for optimizing medical decisions. Estimated cost savings are over one million dollars annually with a PCSH. Since APC-like clinics are common, our findings have great potential for widespread implementation of similar PCSH models with commensurate benefits.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"4 1","pages":"119 - 134"},"PeriodicalIF":0.0,"publicationDate":"2014-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2014.922142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such risks are often associated with harm resulting from errors in medication, diagnosis, and clinical procedures, among others. Preventing harm to patients demands the timely identification of risks to support the selection and implementation of effective strategies. While identifying and assessing risks in healthcare are particularly challenging due to the ambiguity and uncertainty that characterize such systems, most of the risk analysis methods currently used or proposed in healthcare have been developed for systems where unsafe conditions and risk metrics are well-defined. Therefore, their actual use in healthcare systems is inconsistent. The objective of this paper is to provide systems engineers, and researchers from related fields, with an overview of the current state of healthcare risk analysis and to highlight research contributions needed to support the proactive identification and assessment of risks in healthcare systems.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"4 1","pages":"104 - 88"},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2014.911786","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An ambulance dispatched to a call serves patient on site and, if it is necessary to transfer to an emergency department (ED), a decision has to be made in selecting an appropriate hospital. The hospital selection is closely associated with the response time especially by influencing the availability of ambulances. The hospital selection problem is getting increasingly important because of the crowding problems EDs are struggling with. In this research, the impact of various hospital selection policies (including the diversion policy popularly used in practice) on response time is systematically investigated and a novel hospital selection policy—3C policy—is proposed that integrates three decision principles of closeness, congestion, and centrality. The experimental results demonstrate that the proposed policy significantly and robustly outperforms other policies, e.g. reducing response time by up to 90% over diversion policy. The 3C policy emphasizes the critical role that networking and information technology will play in measuring and communicating information associated with the policy.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"4 1","pages":"105 - 117"},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2014.914608","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
