Table 1 Sample conceptual framework of measures of ICU capacity strain

From: Quality and performance measures of strain on intensive care capacity: a protocol for a systematic review

Health care quality dimension Structure Process Outcome
Safe Nurse to patient ratio ICU-averaged TISS score Adverse event rate
Effective ICU census Delay to ICU admission rate Adverse event rate
Mortality rate
Efficient ICU discharge protocol After-hours discharge rate Unplanned ICU readmission rate
Equity GOC designation GOC discussion documentation Refusal rate
Family satisfaction
Patient-centered Family present at ICU bedside rounds Time to family conference after admission HRQL
Family satisfaction
Timely ICU bed occupancy Queuing
Avoidable ICU bed days
Adverse event rate
Mortality rate
