Abstract

OBJECTIVE:

Document trends in time to post-discharge follow-up visit for Medicare patients with an index admission for heart failure (HF), acute myocardial infarction (AMI), or community-acquired pneumonia (CAP). Determine factors predicting whether the first post-discharge utilization event is a follow-up visit, treat-and-release emergency department (ED) visit, or readmission.

METHODS:

Using Medicare claims data from 2007-2010, we plotted annual cumulative incidence functions for the time frame post-discharge to follow-up visit, accounting for competing risks with censoring at 30 days. We used multinomial probit regression to determine factors predicting the probability of first-occurring post-discharge utilization events within 30 days.

RESULTS:

For each cohort, the cumulative incidence of follow-up visits increased during the study period. For example, in 2010, 54.6% of HF patients had a follow-up visit within 10 days of discharge compared to 47.9% in 2007. Within each cohort, the largest increase in follow-up visits took place between 2008 and 2009. Follow-up visits were less likely for patients who were Black, Hispanic, and enrolled in Medicaid or Medicare Advantage, and they were more likely for patients with greater comorbidities and prior procedures as well as those with private or supplemental Medicare coverage. There were no changes in 30-day readmission rates.

DISCUSSION:

Although increases in follow-up visits may have been inf luenced by the introduction of publicly reported readmission rates in 2009, these increases did not continue in 2010 and were not associated with a change in readmissions. Patients who were Black, Hispanic, and/or enrolled in Medicaid or Medicare Advantage were less likely to have follow-up visits.
