(A) Number of index hospitalizations by year for those with (orange) and without (purple) 30-day all-cause readmission. (B) Yearly readmissions presented as a proportion of those with (orange) and without (purple) 30-day all-cause readmission. Only California and New York State Inpatient Databases collect admission year as a distinct variable, hence Florida data are not included here. *As data were available for only the first 3 quarters of 2011, fourth quarter hospitalizations were extrapolated based on the average number of admissions in each of the first 3 quarters of 2011.
