Acute cardiac care & resuscitationCohort study
Impact of Inpatient Percutaneous Coronary Intervention Volume on 30-Day Readmissions After Acute Myocardial Infarction-Cardiogenic Shock
- Retrospective cohort study
- Nationwide Readmissions Database
Authors' conclusion
In AMI-CS, there was no association between hospital annual PCI volume and 30-day readmissions despite higher acuity in the higher volume PCI centers suggestive of better care pathways for CS at higher volume centers.
Study context
- Population
- Adult AMI-CS patients, Nationwide Readmissions Database, 2016–2019admissions, 3,954 hospitals
- Participants
- 49,558 patients
- Exposure
- Hospital annual inpatient percutaneous coronary intervention (PCI) volume quartiles
- Outcome
- 30-day all-cause, cardiac, noncardiac and HF readmissions
- Follow-up
- 30 days
Main finding
As reported in the abstract
30-day readmissions by hospital PCI volume quartile
All-cause
Cardiac
HF
Noncardiac
- All-cause readmission, Q1 to Q4: 17.6%, 18.4%, 18.2%, 18.7%; no difference
- P = 0.55
- Cardiac readmission, Q1 to Q4: 10.9%, 11.0%, 10.6%, 10.2%; no difference
- P = 0.29
- Heart-failure (HF) readmission, Q1 to Q4: 5.0%, 4.8%, 4.8%, 4.8%; no difference
- P = 0.99
- Noncardiac readmission, Q1 to Q4: 6.7%, 7.4%, 7.7%, 8.5%; more common in higher quartiles, not significant after multivariable adjustment
- P = 0.001
- Overall 30-day readmission rate
- 18.5%
Observational data: associations, not effects.
