3. Figure 2
Number of hospitalizations in the prior year by whether or not readmission occurred within 30 days of discharge. Each bar represents the frequency of 30-day readmissions (y-axis) based on the number of hospitalizations due to sickle cell disease (SCD) of a given patient in the previous year (x-axis). Patients with fewer than 5 hospitalizations in the previous year had 18% frequency of readmission in 30 days. In contrast, patients with 5 or more hospitalizations in the previous year had a readmission frequency of 75%. This figure represents 158 first admissions for 88 patients over 3 years, so some patients are included more than once in these calculations.

4. Figure 3
The predicted probability of a readmission within 30 days in adults with sickle cell disease (SCD), with and without hospitalization vs the number of hospitalizations in the prior years. The blue curve shows patients that did not have a primary care provider (PCP) during the time of the study, and the green curve shows patients that had a PCP. Patients without a PCP required about 3 fewer hospitalizations to be predicted to have a readmission.
