Pre- vs Post-COVID-19 Pandemic Risk-adjusted Survival Rates in the US Hospitals: Retrospective Cohort Study of Hospital Performance
Pre- vs Post-COVID-19 Pandemic Risk-adjusted Survival Rates in the US Hospitals: Retrospective Cohort Study of Hospital Performance
This study aims to perform a retrospective cohort study of administrative health data to understand how care delivery performance varies across US hospitals post-COVID-19 pandemic compared to the pre-pandemic performance. We also hope to identify which factors contribute to performance changes.
The study cohort will include one random encounter per patient for all adult (age ≥18years) encounters. All inpatients with the Premier healthcare database (PINC-AI) and those patients who were admitted under observation status and expired in the hospital or those who presented acutely to the emergency department and died in the emergency department will be considered as inpatients for the purpose of this study as per prior precedence in including such patients.
All pediatric inpatients, skilled nursing facilities inpatients, long term acute care inpatients, rehabilitation facility inpatients, psychiatric inpatients, hospice inpatients, chemical dependency unit inpatients and deceased organ donor inpatients are excluded after applying encounter level exclusion criteria from this inpatient cohort. Application of this encounter level exclusion will also preferentially exclude any children hospitals, skilled nursing facilities, acute long term care facilities, psychiatry hospitals, inpatient hospices and chemical dependency units.
