Table 1 Time frame definitions in the ED

From: The cost-effectiveness of upfront point-of-care testing in the emergency department: a secondary analysis of a randomised, controlled trial

Administrative timeTreatment time
Time from patient arrival to doctor evaluationTime from doctor evaluation to disposition decision
All patients go through the same process of opening a file and registering on the hospital system in our ED.After a disposition decision is made, the patient may or may not timeously leave the ED.
The administrative process can be substantially longer on some days than on other days. This would change the wait-times for the patients prior to them presenting to the doctor and would confound the time measurements overall and therefore impact on the cost analysis.Exit block may lead to a delay in the patient leaving the ED even if a timeous disposition decision is made.
Only treatment time was evaluated.The disposition decision time was utilised.
