Essays On Perioperative Services Problems In Healthcare, Amogh S. Bhosekar
All Dissertations
One of the critical challenges in healthcare operations management is to efficiently utilize the expensive resources needed while maintaining the quality of care provided. Simulation and optimization methods can be effectively used to provide better healthcare services. This can be achieved by developing models to minimize patient waiting times, minimize healthcare supply chain and logistics costs, and maximize access. In this proposal, we study some of the important problems in healthcare operations management. More specifically, we focus on perioperative services and study scheduling of operating rooms (ORs) and management of necessary resources such as staff, equipment, and surgical instruments. We …

A maturity model, the Smart Maturity Model for Health Care (SMMHC), is a tool designed for maturity assessment. A four-step implementation plan was also created in this research. The implementation plan views the maturity of the institute and develops a strategy on how to improve it. The research utilized Integrated …
Comparing And Improving The Design Of Physical Activity Data Visualizations, Peter M. Frackleton
Comparing And Improving The Design Of Physical Activity Data Visualizations, Peter M. Frackleton
Masters Theses
Heart disease is a leading cause of death in the United States, and older adults are at highest risk of being diagnosed with heart disease. Consistent physical exercise is an effective means of deterring onset of heart disease, and physical activity tracking devices can inspire greater activity in older adults. However, physical activity tracking device abandonment is quite common due to limitations on what can be learned from the activity data that is collected. Better data visualization of physical data presents an opportunity to surpass these limitations. In this thesis, a task-based human subject study was performed with three different …
A Model For Assessing Staff Resilience To Improve Organizational Resilience In Emergency Departments, Stefani Baz
A Model For Assessing Staff Resilience To Improve Organizational Resilience In Emergency Departments, Stefani Baz
Honors Undergraduate Theses
Organizational Resilience is defined as the ability of an organization to anticipate sudden disruptions, effectively respond, and adapt in a changing environment to deliver its objectives, as well as successfully recover. In order to increase resilience at an organizational level, it is important to understand how individuals collectively contribute to resilience capability of an organization. Emergency Departments (EDs) are considered to be particularly well suited to investigating resilience capability due to their highly unpredictable and complex operating environment. Further, the resilience capability of EDs and their staff is suggested to be essential to successful delivery of safe, high-quality, and timely …
Barriers And Facilitators Influencing Compliance With Enhanced Recovery After Surgery Protocol: A Qualitative Study, Paige Boudreaux
Barriers And Facilitators Influencing Compliance With Enhanced Recovery After Surgery Protocol: A Qualitative Study, Paige Boudreaux
LSU Master's Theses
Standardization in many industries has proven to lead to improved productivity and efficiency, however, standard practice in healthcare has proven difficult due to patient and physician variation. Evidence-based practices provide an opportunity to create more standardization. Enhanced Recovery After Surgery (ERAS) programs are attempting to standardize the surgical pathways of patients by implementing standard evidence-based steps, beginning in the surgeons office and continuing through a patients discharge (Ljungqvist, Scott, & Fearon, 2017). Implementing ERAS to standardize the surgical care of patients has shown to improve patient outcomes, reduce length of stay and reduce readmissions, however, there is a lack of …
The Application Of Usability Engineering Methods To Evaluate And Improve A Clinical Decision Support System, Kristine Desotto
The Application Of Usability Engineering Methods To Evaluate And Improve A Clinical Decision Support System, Kristine Desotto
Masters Theses
Delays in the process of diagnosing and treating cancer are common and lead to confusion and undesirable outcomes. Care coordinators are often embedded within the system of care to manage follow-up care. Electronic and real-time reminder systems can be used to support the care coordinator’s work, but electronic health record (EHR) usability is known to be poor. This study, completed in collaboration with the Department of Veterans Affairs (VA) Connecticut Healthcare System, evaluated the Cancer Coordination and Tracking System (CCTS), an EHR-linked, web-based tool for cancer care management.
A set of expert-driven and user-driven usability engineering methods was applied to …
Ensemble Machine Learning To Predict Family Consent For Organ Donation, Md Ehsan Khan
Ensemble Machine Learning To Predict Family Consent For Organ Donation, Md Ehsan Khan
Graduate Dissertations and Theses
There is ever increasing disparity between number of organs needed for transplantation and numbers available for donation to save lives. As a result, thousands of people die every year waiting for organs. Therefore, it is now more important than ever before to take serious actions to decrease this disparity. One way to bridge gap between organ demand and supply is to increase family consent for organ donation. This research studied the factors associated with family consent. Machine Learning approach had been used in very few literature to understand factors related to family consent. This study uses six Ensemble Machine Learning …
Healthcare Utilization Awareness And Labor Monitoring Methodology: A Theoretical I.M.S.E. Approach To Risk Minimization And Human Metrics Capturing In The Nursing Workforce, Luis Reyes
Open Access Theses & Dissertations
The healthcare industry is so complex and dynamic that the development of any tool designed to promote positive patient outcomes nearly requires the developer to be an actual healthcare practitioner. Many healthcare tools exists that initially give the perception that there will be no future requirements that may hinder the tools' integrity, but more often than not, the unexpected occurs. The future is one unpredictable element of life that most engineers wish they could capture with optimal precision. I.M.S.E. (Industrial, Manufacturing and Systems Engineering) applications do not assist with fortune telling, but they do assist with creating robust tools designed …
The Effect Of Interruptions On Primary Task Performance In Safety-Critical Environments, Cheryl Ann Nicholas
The Effect Of Interruptions On Primary Task Performance In Safety-Critical Environments, Cheryl Ann Nicholas
Doctoral Dissertations
Safety critical systems in medicine utilize alarms to signal potentially life threatening situations to professionals and patients. In particular, in the medical field multiple alarms from equipment are activated daily and often simultaneously. There are a number of alarms which require caregivers to take breaks in complex, primary tasks to attend to the interruption task which is signaled by the alarm. The motivation for this research is the knowledge that, in general, interrupting tasks can have a potentially negative impact on performance and outcomes of the primary task. The focus of this research is on the effect of an interrupting …
Large-Scale Solution Approaches For Healthcare And Supply Chain Scheduling, Ridvan Gedik
Large-Scale Solution Approaches For Healthcare And Supply Chain Scheduling, Ridvan Gedik
Graduate Theses and Dissertations
This research proposes novel solution techniques for two real world problems. We first consider a patient scheduling problem in a proton therapy facility with deterministic patient arrivals. In order to assess the impacts of several operational constraints, we propose single and multi-criteria linear programming models. In addition, we ensure that the strategic patient mix restrictions predetermined by the decision makers are also enforced within the planning horizon. We study the mathematical structures of the single criteria model with strict patient mix restrictions and derive analytical equations for the optimal solutions under several operational restrictions. These efforts lead to a set …
Time-Driven Activity-Based Costing For Healthcare Provider Supply Chain Processes, Martha Isaura Gonzalez
Time-Driven Activity-Based Costing For Healthcare Provider Supply Chain Processes, Martha Isaura Gonzalez
Graduate Theses and Dissertations
In a time when healthcare costs continue to rise, nearly a third of hospital operating expenses are related to supplies, and the healthcare supply chain is complex, it is pertinent for healthcare providers to have a clear understanding of their healthcare supply chain process costs. Having a clear picture into how these costs are driven and where opportunities for cost reductions exist can support supply chain efficiencies. In this research, we develop a Time-Driven Activity-Based Costing (TDABC) supply chain cost management tool for healthcare providers. A TDABC management system can provide healthcare providers with valuable product and process supply chain …

Rfid Technology Selection And Economic Justification For Healthcare Asset Tracking, Tyler Robert Peabody, Tali Freed
Rfid Technology Selection And Economic Justification For Healthcare Asset Tracking, Tyler Robert Peabody, Tali Freed
Master's Theses
Although Radio Frequency Identification (RFID) and Real-Time Location System (RTLS) technologies for inventory tracking have been growing in popularity, the healthcare industry has been reluctant to adopt these technologies. One of the primary reasons for this lack of enthusiasm has been the risk associated with electromagnetic interference between RFID/RTLS systems and medical equipment functionality. The other reason has been the substantial cost and complexity of implementing RFID/RTLS in healthcare organizations. In this study, we show that there are several ways to safely install RFID/RTLS systems to improve the inventory management processes of hospitals and clinics. We then analyze the inventory …
