This document discusses improving patient experience times (PET) in emergency departments (ED). It outlines the current poor ED PET performance nationally and at example hospitals. Reasons for delays include medical personnel, bed capacity, and delayed radiology and laboratory results. The document proposes introducing push notifications to alert clinicians when radiology and laboratory results are available to reduce waiting times. It discusses reengineering the process, conducting a pilot, and implementing change while managing resistance from stakeholders. The goal is to improve the patient experience and flow through EDs.
