Emergency Department (ED) overcrowding continues to be a public health issue as well as a patient safety issue. The underlying factors leading to ED crowding are numerous, varied, and complex. Although lack of in-hospital beds is frequently attributed as the primary reason for crowding, ED's dependencies on other ancillary resources, including imaging, consults, and labs, also contribute to crowding. Using retrospective data associated with imaging, including delays, processing time, and the…

Identification of root causes for emergency diagnostic imaging delays at three Canadian hospitals.

A discrete event simulation to evaluate impact of radiology process changes on emergency department computed tomography access.

Adding one transporter provided the greatest combination of reduced delay and ability to implement for CT access time for emergency department patients at a large academic medical center with six unique CT machines.

Analysis of factors influencing length of stay in the emergency department.

Triage level, investigations and consultations are important independent variables that influence ED LOS, and future research is necessary to determine how these and other factors can be incorporated into a model for predicting LOS.

Does improved access to diagnostic imaging results reduce hospital length of stay? A retrospective study

The results did not indicate that improved access to radiology results reduced the patients' LOS, but there was a significant reduction in LOS for patients undergoing CT scans, given the clinicians' interest in CT reports and the results of the subgroup analyses.

Physician Shift Scheduling to Improve Patient Safety and Patient Flow in the Emergency Department

It is observed that patient time in the ED and handoffs can be reduced by as much as 27% and 26%, with a 1.4% increase in full-time equivalents compared to the current practices.

Emergency department crowding, part 1--concept, causes, and moral consequences.

Emergency physician perceptions of medically unnecessary advanced diagnostic imaging.

Solutions most commonly felt to be "extremely" or "very" helpful for reducing unnecessary imaging included malpractice reform, increased patient involvement through education and shared decision-making and improved education of physicians on diagnostic testing.

Patient Care Management for Physicians: Reducing Handoffs in the ED

A simulation model was developed to test various physician to patient assignment policies to minimize the number of handoffs and reduce the workload at the end of a shift.
