Quantile regression model producing predicted percentiles of total payments from the date of rehospitalization to 30-days after rehospitalization by rehospitalization facility (same or different), overall and stratified by index hospital for-profit status, controlled for patient characteristics of age, gender, race, Medicaid and disability status, comorbidities (hypertension, fluid and electrolyte disorders, congestive heart failure, chronic pulmonary disease, deficiency anemias, diabetes-uncomplicated, valvular disease, hypothyroidism, peripheral vascular disorders, cardiac arrythmias, and an indicator denoting the presence of other comorbidity), index hospital length of stay and Center for Medicare and Medicaid Service’s Hierarchical Condition Category Score; and Index hospital characteristics of annual discharge number, teaching status, for-profit status (omitted in stratified models), billing region and rural-urban community area code. 95% Confidence intervals were bootstrapped using 1000 analytic repetitions.
