Data based on Medicare fee-for-service patients aged 65 or over between 1 January 2012 and 1 October 2015. Target conditions include heart failure, acute myocardial infarction, or pneumonia.
P value for difference in monthly change among subgroups.
Among patients with multiple hospital revisits within 30 days of discharge, only the first revisit for each type of encounter was counted.
Among patients with multiple hospital revisits within 30 days of discharge, all visits for each type of encounter were counted.
