Determination Of Number Of Dedicated Or's And Supporting Pricing Mechanisms For Emergent Surgeries, Leo Macdonald, Jomon Aliyas Paul
Determination Of Number Of Dedicated Or's And Supporting Pricing Mechanisms For Emergent Surgeries, Leo Macdonald, Jomon Aliyas Paul
Jomon Aliyas Paul
Inefficient management of emergent surgeries in hospitals can, in part, be attributed to a lack of rigorous analysis appropriate to capturing the underlying uncertainties inherent to this process and a pricing mechanism to ensure its financial viability. We develop a non-preemptive multi-priority queueing model that optimally manages emergent surgeries and supports the resource allocation decision-making process. Specifically, we utilize queueing and discrete event simulation to develop empirical models for determining the required number of emergent operating rooms for a hospital surgical department. We also present algorithms that estimate the appropriate pricing for patient surgeries differentiated by priority level given the …
A Model To Study Disparities And Lifetime Medical Costs, Jomon Aliyas Paul, Leo Macdonald, Govind Hariharan
A Model To Study Disparities And Lifetime Medical Costs, Jomon Aliyas Paul, Leo Macdonald, Govind Hariharan
Jomon Aliyas Paul
We develop a mathematical model that captures the complex interactions within the health service system featuring chronic diseases and provides valuable lessons that could assist in controlling escalating healthcare costs. We utilize a Monte Carlo simulation framework to simulate the evolution of a population subject to deaths, births, and disease conditions. The model estimates the lifetime health expenditures of individuals based on demographics including race, age, and gender, as well as risk factors that contribute to the development of specific disease conditions. We further incorporate interactions between multiple disease conditions and the effect of risk factors in chronic disease incidence …
Models Using The Benefits Of Cross Training Policies To Tackle Nurse Shortage Crisis, Jomon Paul, Leo Macdonald
Models Using The Benefits Of Cross Training Policies To Tackle Nurse Shortage Crisis, Jomon Paul, Leo Macdonald
Jomon Aliyas Paul
This paper seeks to offer insight into cross training strategies that could be effective in aiding in alleviating the nurse shortage issue and its potential to negatively impact on patient safety and mortality. We develop optimization models to evaluate the benefits of cross-training, in particular chaining practices, on nurse workforce planning under stochastic demand, and determine the optimal allocation of both regular and cross-trained staff at a minimum cost. We demonstrate the benefits of cross-training in terms of a reduction in the total number of nurses required to satisfy demand across multiple departments as well as from an economic (i.e. …
A Process Flow Based Framework For Nurse Demand Estimation To Address Nurse Shortage., Jomon Paul, Leo Macdonald
A Process Flow Based Framework For Nurse Demand Estimation To Address Nurse Shortage., Jomon Paul, Leo Macdonald
Jomon Aliyas Paul
The nursing shortage in the United States poses a serious problem to hospitals, given that nurses provide an indispensable service within the healthcare system. This issue is expected to worsen, especially given the aging population of baby-boomers, which includes those that are part of the nurse workforce. This has resulted in a wide variety of problems, including patient safety issues, inability to detect complications, and potential patient mortality rate increases. Nurse shortage implications go beyond healthcare quality, extending to health economics as well. Inaccurate estimates of the nursing resources required to satisfy patient demand in a hospital environment could make …
Efficient Operating Room Redesign Through Process Improvement And Optimal Handling Of Scheduled And Emergent Surgeries, Jomon Paul, Arun Jotshi
Efficient Operating Room Redesign Through Process Improvement And Optimal Handling Of Scheduled And Emergent Surgeries, Jomon Paul, Arun Jotshi
Jomon Aliyas Paul
This article is focused on the benefits of reducing variability and the role of Operations Research techniques in efficient operating room (OR) redesign through process improvement and optimal management of scheduled and emergent surgeries at hospitals. Issues at a participant hospital are studied which are presented in this article where in the authors develop a three step OR redesign model to address them. The three step redesign was carried out as follows. Firstly, the process bottlenecks affecting OR performance were identified with the help of a Discrete Event Simulation Model (DES). Once the DES model focusing on the “As-Is” operations …

Models For Solving Emergency Room Crisis., Jomon Aliyas Paul, Kedar Sambhoos

Emergency Departments (ED) across United States are distraught with issues like overcrowding, ambulance diversion, medical errors, patient left without being seen etc. The primary cause for all these interrelated problems is artificial variability that results mainly because of inaccurate severity estimation leading to inappropriate bed allocation and final disposition. To this effect, we propose Bayesian decision support tools that accurately classify new incoming patients into different severity types based on their chief complaints and at the same time assist doctors in subsequent diagnosis and disposition of patients. These tools are developed based on the decision making principles of attending physicians …

Simulation And Lean Six Sigma Integration For Improvement Of Hospital Operations., Jomon Aliyas Paul, Li Lin
Jomon Aliyas Paul
Patient throughput has become one of the most common measures of hospital performance in terms of patient satisfaction and operational efficiency. Throughout the country hospital emergency departments, which generally supply almost 50% of the inpatient population, face increased pressure on improving patient flow. Similarly performance of ORs, the largest revenue grosser for the hospital significantly affects the patient satisfaction considerably. In addition to employing a DMAIC - Lean Six Sigma approach to resolve these problems, In simulation has been used as an excellent tool to implement the Analyze and Improve phases of the six-sigma methodology. We used simulation, integrated with …
