Data Visualization Of Treatment Outcomes For Tuberculosis Patients, Joy Jenkins
Data Visualization Of Treatment Outcomes For Tuberculosis Patients, Joy Jenkins
Industrial Engineering Undergraduate Honors Theses
Tuberculosis is an infectious disease, and different treatments have been discovered over the years. However, patients may develop various drug resistance levels that affect the likelihood of becoming cured or dying. In this study, we sought to employ data visualization to explore the relationship between treatment trajectory, as indicated by smear and culture results in the follow-up tests and patient outcomes. A large sample of patients have been broken down by demographics including age, gender, and drug resistance status. Sankey diagrams were used to visualize the pathway progression of the patients over time split between two time periods- months 0-6 …
Simulating Alternative Tuberculosis Diagnosis Methods In Underdeveloped Countries, Luke Turner
Simulating Alternative Tuberculosis Diagnosis Methods In Underdeveloped Countries, Luke Turner
Industrial Engineering Undergraduate Honors Theses
Tuberculosis is the deadliest infectious disease in the world; it is especially rampant in underdeveloped countries because they do not have the infrastructure, technology, or funding to properly combat the infection. However, the development of portable point-of-care diagnosis machines can reverse this epidemic as they far surpass conventional laboratory identification. The question now is where to place these machines, which is a difficult decision with a lack of data. Therefore, a flexible simulation model is created to test the implementation of these machines with different countries and configurations. The simulation tests the baseline model and three proposed implementations of the …
Essays In Physicians Preference Items And Inventory Management Within The Healthcare Supply Chain, Mohammad A. Shbool
Essays In Physicians Preference Items And Inventory Management Within The Healthcare Supply Chain, Mohammad A. Shbool
Graduate Theses and Dissertations
This work is composed of a number of topics in the healthcare area, which are approached separately with appropriate methodologies. The two topics deal with physician preference items via two different approaches. The first one investigates stock keeping unit (SKU) proliferation in healthcare organizations due to physician preference items (PPI). It captures perspectives of physicians and supply chain professionals about this problem through two surveys. The second topic builds a decision-making framework for the PPI selection process that can be used by healthcare organizations to make more objective decisions. A Multi-criteria decision making technique is implemented to illustrate the framework.
Improving Reliability Of Medical Device Tracking Using Unique Device Identification, John A. Bonfanti
Improving Reliability Of Medical Device Tracking Using Unique Device Identification, John A. Bonfanti
Industrial Engineering Undergraduate Honors Theses
The term “disruptive innovation” has been the buzzword of industries looking to create technological advancements in their respective fields ever since the term was first coined in 1995. In order to invest in the future of the industry, companies are beginning to focus on new, innovative ideas that come into the market as a low-cost alternative to the sustaining innovations currently in place. Similar business-models can be seen in the healthcare industry, as physicians look to disruptive innovations to provide methods of diagnosis and treatment that are easier to perform and maintain. Companies, from medical device manufacturers to the hospitals …
Modeling The Adoption Of Identification Standards Within The Healthcare Supply Chain, Angelica Burbano
Modeling The Adoption Of Identification Standards Within The Healthcare Supply Chain, Angelica Burbano
Graduate Theses and Dissertations
The adoption of identification standards and its associated technology in the healthcare supply chain has been slow over the past twenty five years, despite the evidence of the benefits that can be achieved. The widespread use of identification standards in the form of barcode labeled medical products can contribute to the reduction of point of care errors and can increase the efficiency of healthcare supply chain related processes. This research is focused on the analysis of the adoption of identification standards in the healthcare supply chain with a particular focus on the healthcare provider adoption challenges. The research is divided …
Evaluating The Capacity Of A Proton Therapy Facility, Ridvan Gedik
Evaluating The Capacity Of A Proton Therapy Facility, Ridvan Gedik
Graduate Theses and Dissertations
A relatively new consideration in proton therapy planning is the requirement that the mix of patients treated satisfy desired percentages. Since it is very dicult to satisfy an integer number of patients in light of these requirements, deviations from patient mix preferences and their impacts on operational capabilities are of particular interest to healthcare planners. Therefore, we propose a bicriteria mathematical programming model that determines an outpatient schedule maximizing the number of fractions and minimizing the deviations from the patient mix ratios over the planning horizon. The tradeos between the two objectives are identied through analysis of ecient frontiers. Our …
Applying Inventory Control Practices Within The Sisters Of Mercy Health Care Supply Chain, Server Apras
Applying Inventory Control Practices Within The Sisters Of Mercy Health Care Supply Chain, Server Apras
Graduate Theses and Dissertations
This research lays a foundation for the better understanding of the application and acceptance of more advanced inventory control practices within the health care supply chain. The demand characteristics and optimal control policies for pharmaceutical items within a multi-echelon provider network are examined within the framework of a case study. Demand forecasting algorithms were applied to forecast demand for inventory control procedures. A spreadsheet-based inventory planning tool was used to minimize the inventory holding and ordering costs subject to fill rate constraints. The costs of inventory control models are compared to the current ordering and inventory control strategies to document …
