Waiting times in emergency departments: a resource allocation or an efficiency issue?

Abstract

Background: In recent years, the flow of patients to the Emergency Departments (ED) of Western countries has steadily increased, thus generating overcrowding and extended waiting times. Scholars have identified four main causes for this phenomenon, related to: continuity of primary care services; availability of specific clinical pathways for chronic patients; ED's personnel endowment; organization of the ED. This study aims at providing a logical diagnostic framework to support managers in investigating specific solutions to be applied to their EDs to cope with high ED waiting times. The framework is based on the ED waiting times and ED admission rate matrix. It was applied to the Tuscan EDs as illustrative example. Methods: To provide the factors to be analyzed once the EDs are positioned into the matrix, a list of issues has been identified. The matrix was applied to Tuscan EDs. Data were collected from the Tuscan performance evaluation system, integrated with specific data on Tuscan EDs' personnel. The Tuscan EDs matrix, the descriptive statistics for each quadrant and the Spearman's rank correlation analysis among waiting times, admission rates and a set of performance indicators were conducted to help managers to read the phenomena that they need to investigate. Results: The combined reading of the correlations and waiting times-admission rates matrix shows that there are no optimal rules for all the EDs in managing admission rates and waiting times, but solutions have to be found considering mixed and personalized strategies. Conclusions: The waiting times-admission rates matrix provides a tool able to support managers in detecting the problems related to the management of ED services. In particular, using this matrix, healthcare managers could be facilitated in the identification of possible solutions for their specific situation.

Hospital complications among older adults: Better processes could reduce the risk of delirium

“…In a healthcare management framework, common factors associated with ED boarding could be grouped into four main categories: a) how primary care and continuity are organized, b) the existence and effectiveness of organizational models and clinical pathways for chronic patients, c) the presence of bottlenecks related to ED's personnel or equipment endowment, and d) how the ED is organized and its connection with the rest of the hospital (Vainieri et al, 2020). Our study may help healthcare managers to identify feasible targets for process improvement in the connection between ED and the rest of the hospital (e.g., a sensible elective surgery's schedule).…”

Solutions for improved hospital-wide patient flows – a qualitative interview study of leading healthcare providers

“…There is an ongoing debate within healthcare services on what decision-makers and healthcare managers should do to improve the financial situation as costs continue to rise without an equivalent gain in productivity [ 3 , 8 , 9 ]. The question looming is whether productivity improvements can be reached with or without increasing available resources [ 6 , 11 ]. This study gives good insights into the thoughts of senior managers at the world’s leading hospitals concerning the best path ahead.…”

Validity of Wait Time Complaints and Effect of Trainee Presence in an Ophthalmic Emergency Department

“…The implications of a prolonged waiting in the emergency room have been described, which highlight the need for efficiency and adequate staffing. 6 , 7 , 14 , 15 While this task is complicated when institutional objectives include providing quality trainee education, efforts aimed at improving overall efficiency should focus on optimizing workflow and trainee efficiency.…”
