Multitasking and interruptions while making diagnostic decisions have been frequently observed in the healthcare work environment. However, little evidence from controlled experiments is available to determine whether physician multitasking affects the quality and timely performance of diagnostic decisions. In the current study, we designed a diagnostic task to examine the effects of concurrent tasks on diagnostic decision making using a controlled laboratory experiment, in which potential confounding factors were controlled to allow the quantification of diagnostic performance and strategies. The results showed that diagnostic performance was negatively affected by a complex concurrent memorization task that required participants to listen to verbal updates and remember information about other patients while performing the diagnostic task. In contrast, a simple concurrent sound monitoring task did not affect diagnostic performance. Both types of concurrent tasks significantly increased mental workload. Diagnostic decision strategies were not significantly different between the single- and dual-task conditions. These findings provide new insights into the cognitive mechanisms underlying diagnostic decision and physician multitasking. Implications for the control and improvement of healthcare quality are discussed.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"3 1","pages":"254 - 262"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2013.858378","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564043","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}

Most medication error studies to date have focused on reporting patient misidentification statistics from case studies, on classifying types of patient identification errors, or on evaluating the impact of technology on the patient identification process, but few have proposed specific strategies or guidelines to decrease patient identification errors. Our study makes three key contributions to the patient identification literature. To better understand the verification of patient identifiers (VPI) process, we first formalize the requirements for this process based on the Joint Commission's national patient safety guidelines. Second, we show the implications of these requirements by applying them to artifacts typically used in medication administration (e.g., patient's statements about their identity, patient's identification band, medication label, and medication order). Third, we evaluate whether nurses comply with these requirements when administering medications using data from clinical simulations. We found that nurses must choose from a considerable number of alternatives to fulfill the Joint Commission guidelines. Despite the number of available alternatives, a small percentage of nurses complied with the requirements for VPI, whether doing so manually or using barcode verification technology. Our findings suggest further study is needed to determine what strategies might improve compliance.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"3 1","pages":"280 - 291"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2013.862329","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564207","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}

However, there has been very limited research that analyzes the impact of overbooking on the major causes/factors of patient no-show and most importantly, its implications on patient no-show. In this paper, we take a novel approach and develop a game-theoretic framework (with queueing models) to explore the impact of overbooking on patient no-show through its effect on two important factors shown to affect no-show: appointment delay (time between a patient requesting an appointment and his actual appointment time) and office delay (the amount of time a patient waits in the office to see the doctor). While overbooking reduces appointment delay (which may positively affect patient no-show rate), it increases office delay (which may negatively affect patient no-show rate). Our results show that, considering both impacts of appointment delay and office delay, patient no-show rate always increases after overbooking. Further, there exists a critical range of patient panel size within which overbooking may also lead to lower expected profit for the clinic. Correspondingly, we propose two easy-to-implement strategies, which can increase clinic’s expected profit and reduce no-show at the same time.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"3 1","pages":"147 - 170"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2013.820239","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60563508","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}

However, keeping high availability can result in high expiry of slow-moving medical items because of their finite lifetimes. Lateral transshipment between inventory locations has been reported to reduce expiry of blood products, which are fast-moving. This paper extends lateral transshipment to slow-moving critical items in a medical system to reduce expiry and proposes a decision rule. Transshipment may take place when demand happens at a location or when a unit expires. The proposed decision rule takes the myopic-best action at each decision epoch by assuming no transshipments in the future. The rule is iteratively applied at all decision epochs to realize long-term savings. Simulation results demonstrate significant cost savings by the lateral transshipment based on the proposed decision rule. The decision rule works well compared to the upper-bound percentage of total savings. The savings are more considerable when the difference of demand rates between locations is large and the lifetime of the medical item is not too long or too short. The savings could be more significant when the number of locations increases but is bounded. Furthermore, simulation results on an example of Fomepizole demonstrate about 9.5% cost savings realized by lateral transshipment based on the proposed decision rule.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"3 1","pages":"193 - 206"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2013.824524","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60564018","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}

Those with comorbid diseases may be particularly vulnerable. This paper studies the impact of comorbidities, with a particular focus on mental disorders, on HIV patient outcomes as measured by patient length of stay (LOS) and total charges. Generalized linear models (gamma models) allowing heteroscedasticity are developed to characterize the effects of selected comorbidities on HIV patient outcomes in the adult 2006 National Inpatient Sample. Comorbid HIV patients experience different LOS and total charges. In particular, having mental disorders resulted in a decrease in both LOS (19%) and total charges (15%) for HIV patients. To characterize the role of individual mental disorders, principal component and cluster analyses on ICD-9 codes are used to study the impact of mental disorder, and eight conditions are found to be most strongly associated with HIV. Gamma models with these identified mental disorders as independent variables are then developed. The results have shown different effects on LOS and charges for each condition, and special attention should be given to those mental disorders (e.g., drug dependence) that increased LOS and charges when present.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"3 1","pages":"139 - 146"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2013.820238","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60563624","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}

Scheduling surgeries for a single surgeon operating in two parallel operating rooms (ORs) motivates the work. The basic idea is that staff perform cleanup and setup in one OR while the surgeon is operating in the other. The benefit is less waiting time for the surgeon between surgeries, but may also result in added idle time for staff if cleanup and set-up are completed prior to completion of surgery in the other OR. When surgeries are long relative to cleanup and setup times, parallel OR scheduling is not attractive as significant OR and staff idle time will result. The problem we address consists of assigning surgeries to ORs and sequencing them, and is formulated as an integer stochastic program using sample average approximation. A decomposition based solution approach is developed. Computational testing based on real data shows that the proposed methods solve the problems to optimality in acceptable processing times. Using the solution methodology, we conduct additional experiments to provide insight as to the conditions when scheduling a single surgeon in parallel operating rooms is cost effective.","PeriodicalId":89563,"journal":{"name":"IIE transactions on healthcare systems engineering","volume":"3 1","pages":"127 - 138"},"PeriodicalIF":0.0,"publicationDate":"2013-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19488300.2013.787563","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60562960","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}

The suggested protocol, however, can be adapted to address other instances of the RA problem in the context of other infectious disease epidemics. Section 1 defines all the parameters and run conditions for the ABS model. In Section 2 we discuss calibration of the RA objective function (DALYs function) and related sensitivity analyses. An investigation of variance reduction for the ABS model is presented in Section 3. A short discussion on application of mixture design and the corresponding triangular output displays for this design is discussed in Section 4.
