The role of patient perception of crowding in the determination of real-time patient satisfaction at Emergency Department.

Objective: To evaluate the associations between real-time overall patient satisfaction and Emergency Department (ED) crowding as determined by patient percepton and crowding estimation tool score in a high-volume ED.

Design: A prospective observational study.

Setting: A tertiary acute hospital ED and a Level 1 trauma center.

Optimal Measurement Interval for Emergency Department Crowding Estimation Tools.

Study Objective: Emergency department (ED) crowding is a barrier to timely care. Several crowding estimation tools have been developed to facilitate early identification of and intervention for crowding. Nevertheless, the ideal frequency is unclear for measuring ED crowding by using these tools.

Roles of disease severity and post-discharge outpatient visits as predictors of hospital readmissions.

Background: Risks prediction models of 30-day all-cause hospital readmissions are multi-factorial. Severity of illness (SOI) and risk of mortality (ROM) categorized by All Patient Refined Diagnosis Related Groups (APR-DRG) seem to predict hospital readmission but lack large sample validation. Effects of risk reduction interventions including providing post-discharge outpatient visits remain uncertain.

A Derivation and Validation Study of an Early Blood Transfusion Needs Score for Severe Trauma Patients.

Background: There is no existing adequate blood transfusion needs determination tool that Emergency Medical Services (EMS) personnel can use for prehospital blood transfusion initiation. In this study, a simple and pragmatic prehospital blood transfusion needs scoring system was derived and validated.

Methods: Local trauma registry data were reviewed retrospectively from 2004 through 2013.
