These findings are also consistent with a systematic review of results from 37 studies on determinants of readmissions, in which patient-level indicators of general ill health or complexity were shown to be the most commonly identified risk factors for readmissions.2 In this study, after controlling for demographic, clinical, index hospitalization, and health insurance characteristics, as well as health care utilization, readmission rates were higher among those with complexities compared to those without complexities.
