Background: Readmission within 30 days after hospitalization for heart failure (HF) is a major public health problem.
Objective: To examine whether timing and type of post-discharge follow-up impacts risk of 30-day readmission in adults hospitalized for HF.
Design: Nested matched case-control study (January 1, 2006–June 30, 2013).
Setting: A large, integrated health care delivery system in Northern California.
Participants: Hospitalized adults with a primary diagnosis of HF discharged to home without hospice care.
Measurements: Outpatient visits and telephone calls with cardiology and general medicine providers in non-emergency department and non-urgent care settings were counted as follow-up care. Statistical adjustments were made for differences in patient sociodemographic and clinical characteristics, acute severity of illness, hospitalization characteristics, and post-discharge medication changes and laboratory testing.
Results: Among 11,985 eligible adults, early initial outpatient contact within 7 days after discharge was associated with lower odds of readmission [adjusted odds ratio (OR)=0.81; 95% CI, 0.70–0.94], whereas later outpatient contact between 8 and 30 days after hospital discharge was not significantly associated with readmission (adjusted OR=0.99; 95% CI, 0.82–1.19). Initial contact by telephone was associated with lower adjusted odds of 30-day readmission (adjusted OR=0.85; 95% CI, 0.69–1.06) but was not statistically significant.
Conclusions: In adults discharged to home after hospitalization for HF, outpatient follow-up with a cardiology or general medicine provider within 7 days was associated with a lower chance of 30-day readmission.
