Description
For more than twenty years, clinical researchers have been publishing data regarding incidence and risk of adverse events (AEs) incurred during hospitalizations. Hospitals have standard operating policies and procedures (SOPP) to protect patients from AE. The AE specifics (rates, SOPP failures, timing and risk factors) during heart failure (HF) hospitalizations are unknown. There were 1,722 patients discharged with a primary diagnosis of HF from an academic hospital between January 2005 and December 2007. Three hundred eighty-one patients experienced 566 AEs, classified into four categories: medication (43.9%), infection (18.9%), patient care (26.3%), or procedural (10.9%). Three distinct analyses were performed: 1) patient's perspective of SOPP reliability including cumulative distribution and hazard functions of time to AEs; 2) Cox proportional hazards model to determine independent patient-specific risk factors for AEs; and 3) hospital administration's perspective of SOPP reliability through three years of the study including cumulative distribution and hazard functions of time between AEs and moving range statistical process control (SPC) charts for days between failures of each type. This is the first study, to our knowledge, to consider reliability of SOPP from both the patient's and hospital administration's perspective. AE rates in hospitalized patients are similar to other recently published reports and did not improve during the study period. Operations research methodologies will be necessary to improve reliability of care delivered to hospitalized patients.

Description
The current Enterprise Requirements and Acquisition Model (ERAM), a discrete event simulation of the major tasks and decisions within the DoD acquisition system, identifies several what-if intervention strategies to improve program completion time. However, processes that contribute to the program acquisition completion time were not explicitly identified in the simulation study. This research seeks to determine the acquisition processes that contribute significantly to total simulated program time in the acquisition system for all programs reaching Milestone C. Specifically, this research examines the effect of increased scope management, technology maturity, and decreased variation and mean process times in post-Design Readiness Review contractor activities by performing additional simulation analyses. Potential policies are formulated from the results to further improve program acquisition completion time.

Description
The healthcare industry is currently facing significant changes. One of the changes in the industry is a movement towards patient-focused care, which considers the patient as a person and the impact of care on the person. Patient experience is part of patient-focused care, and has similarities to the marketing term customer experience, which contributes to happier customers and long-term financial growth and success for businesses. This thesis defines current issues in patient experience as it relates to hospital manager decision making. Through secondary research, this thesis demonstrates what patient experience is, the role it plays in healthcare and hospital settings, the pressures on hospitals to increase patient experience performance, how patient experience performance is measured, and what strategies or action drive improvements under current performance measurements. Many studies and articles exist examining each of these issues individually. However, these sources do not comprehensively define patient experience in hospitals with perspective on how this influences hospital strategy and decision-making. Previous works on patient experience from the perspective of hospital strategy do not include considerations for recent industry shifts, most notably the Patient Protection and Affordable Care Act. The collected definitions in this thesis provide guidance of relevant concerns hospital managers consider when formulating organization-wide strategy related to patient experience. This thesis explains how patient experience contributes to the success of hospitals in the short-term, medium-term, and long-term and how patient experience may shift its focus over time. Short-term concerns include specific regulations and definitions from the Centers for Medicare and Medicaid services, responsible for over half of all payments to hospitals. Conforming to CMS standards is a matter of survival for most hospitals in the short-term. Hospitals are adjusting to rules and payment models not in existence just two years ago. First, hospitals will adapt, and then hospitals will strive to optimize under new standards as well as respond to adjustments in the rules over the next several years. After patient experience standards are well established, certain aspects of patient experience will be part of long-term differentiation and success for hospitals. Responding comprehensively to the shift towards improving patient experience is a critical aspect for hospitals to weather the many changes in the healthcare industry. Patient experience will provide better care to patients and better financial health to the hospitals that perform above patient experience standards.
