Heart failure & cardiomyopathies
Risk Factors of Readmission and the Impact of Outpatient Management in Heart Failure Patients: A National Study in Japan
Authors' conclusion
This study comprehensively identified risk factors for readmission and found outpatient visit is personalized by readmission risk.
Study context
- Population
- HF patients, Japanese diagnosis-procedure-combination database, April 2016–March 2022analysed
- Participants
- 101,239 patients
- Exposure
- Outpatient visit frequency after discharge: <1, and >2 visits/month
- Outcome
- Readmission (risk factors and association with number of outpatient visits)
- Follow-up
- 60 days
Methodological detailsnational administrative database (diagnosis-procedure-combination), multiple logistic regression
