Multimodal Quality Improvement Intervention With Dedicated Patient Flow Manager to Reduce Emergency Department Length of Stay and Occupancy: Interrupted Time Series Analysis

An Evaluation on the Attitude Toward Using Patient Rights and Satisfaction Levels in Emergency Department Patients

INTRODUCTION

In emergency health care services, patient satisfaction is one of the fundamental indicators of quality emergency care, making it essential to identify factors that can impact this component of care. This study aimed to determine emergency service patients' attitudes toward using patient rights, their satisfaction levels with emergency service, and related factors.

METHODS

The cross-sectional study was conducted with 382 patients who presented to the emergency department between November 2022 and March 2023. Data were collected using the Patient Description Form, the Emergency Department Patient Satisfaction Scale, and the Scale of Patient Rights Using Attitude. The study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for reporting.

RESULTS

The mean score of the Emergency Department Patient Satisfaction Scale was 53.88 ± 6.88 (minimum score, 30; maximum score, 68), and the mean score of the Scale of Patient Rights Using Attitude was 108.89 ± 11.90 (minimum score, 73; maximum score, 135). As a result of the regression analysis, it was found that the Scale of Patient Rights Using Attitude scores and frequency of ED visits significantly contributed to the Emergency Department Patient Satisfaction Scale scores. Younger patients who had higher educational status presented to the emergency department more frequently and had chronic diseases were associated with positive attitudes about using patient rights and had higher levels of ED patient satisfaction (P < .001).

DISCUSSION

The study has provided valuable information for assessing the attitudes of ED patients toward exercising their patient rights and their satisfaction levels. Respect for patient rights and their effective utilization by patients can enhance the quality of ED services and increase patient satisfaction.

Effects of process changes on emergency department crowding in a changing world: an interrupted time-series analysis

BACKGROUND

During a 6-year period, several process changes were introduced at the emergency department (ED) to decrease crowding, such as the implementation of a general practitioner cooperative (GPC) and additional medical staff during peak hours. In this study, we assessed the effects of these process changes on three crowding measures: patients' length of stay (LOS), the modified National ED OverCrowding Score (mNEDOCS), and exit block while taking into account changing external circumstances, such as the COVID-19 pandemic and centralization of acute care.

METHODS

We determined time points of the various interventions and external circumstances and built an interrupted time-series (ITS) model per outcome measure. We analyzed changes in level and trend before and after the selected time points using ARIMA modeling, to account for autocorrelation in the outcome measures.

RESULTS

Longer patients' ED LOS was associated with more inpatient admissions and more urgent patients. The mNEDOCS decreased with the integration of the GPC and the expansion of the ED to 34 beds and increased with the closure of a neighboring ED and ICU. More exit blocks occurred when more patients with shortness of breath and more patients > 70 years of age presented to the ED. During the severe influenza wave of 2018-2019, patients' ED LOS and the number of exit blocks increased.

CONCLUSIONS

In the ongoing battle against ED crowding, it is pivotal to understand the effect of interventions, corrected for changing circumstances and patient and visit characteristics. In our ED, interventions which were associated with decreased crowding measures included the expansion of the ED with more beds and the integration of the GPC on the ED.

Impact of New Bed Assignment Information System on Emergency Department Length of Stay: An Effect Evaluation for Lean Intervention by Using Interrupted Time Series and Propensity Score Matching Analysis

A long waiting period for available beds in emergency departments (EDs) is the major obstacle to a smooth process flow in ED services. We developed a new bed assignment information system that incorporates current strategies and resources to ease the bottleneck in the service flow. The study’s purpose was to evaluate the effect of the lean intervention plan. We included 54,541 ED patient visits in the preintervention phase and 52,874 ED patient visits in the postintervention phase. Segmented regression analysis (SRA) was used to estimate the level and trend in the preintervention and postintervention phases and changes in the level and trend after the intervention. After the intervention, the weekly length of stay (LOS) for patient visits, admitted patient visits, and nonadmitted patient visits decreased significantly by 0.75, 2.82, and 0.17 h, respectively. The trendline direction for overall patient visits and nonadmitted patient visits significantly changed after the intervention. However, no significant change was noted for admitted patient visits, although the postintervention trend visually differed from the preintervention trend. The concept of lean intervention can be applied to solve various problems encountered in the medical field, and the most common approach, SRA, can be used to evaluate the effect of intervention plans.
