DescriptionThis indicator measures the time interval between the Disposition Date/Time (as determined by the main service provider) and the Date/Time Patient Left Emergency Department (ED) for admission to an inpatient bed or operating room.
Interpretation

The 90th or 50th percentile of this indicator represents the maximum length of time that 90% or 50% of patients admitted from the ED wait for an inpatient bed or an operating room in the ED.

A small number is desirable for this indicator.

Background, Interpretation and Benchmarks
Rationale

Time is crucial to the effectiveness and outcome of patient care, especially for emergency patients. In conjunction with other indicators, this can be used to monitor the inpatient bed turnover rate and the total length of time admitted patients spend in the ED in an effort to improve the efficiency and, ultimately, the outcome of patient care.

Many factors can influence the indicator results, including the availability of inpatient beds, the percentage of alternate level of care (ALC) patients, the overall patient population and hospital resources.

Interpretation

The 90th or 50th percentile of this indicator represents the maximum length of time that 90% or 50% of patients admitted from the ED wait for an inpatient bed or an operating room in the ED.

A small number is desirable for this indicator.
