abstract
One of the policy mechanisms aimed at improving population health through health care delivery is the Hospital Readmissions Reduction Program (HRRP) as outlined in the Affordable Care Act. Although numerous procedural and behavioral interventions have been implemented, the empirical evidence of the efficacy of these interventions is mixed and specific to certain patient segments. This review aimed to systematically assess studies of hospital interventions to reduce 30-day readmissions for specific diseases and populations. Following the PRISMA review checklist, searches were conducted from January 2000 to August 2018 in the MEDLINE and EMBASE databases using terms such as patient readmission, readmit and re-hospitalization in conjunction with disease terms such as asthma, chronic obstructive pulmonary disease (COPD) and pneumonia. Of 3,806 articles identified, 45 were included after a 3-step inclusion process. The age group most frequently considered among the studies was the 65 age cohort. Multidisciplinary collaborative interventions were most frequently effective for the subset of elderly, female, Caucasian, and heart failure patients. Interventions involving patient or family education delivered before and after care were most effective for racial minority, elderly, COPD, and heart failure patients. Telephone follow-up, tele-homecare, and medication reconciliation were largely found to be successful in reducing readmissions. Major gaps exist in identifying successful interventions for reducing 30-day readmissions among patients who sought treatment for sepsis, stroke, and replacement of the hip or knee. Our findings indicate an opportunity for researchers to further study, and for healthcare organizations to implement, more well-informed interventional strategies to reduce readmissions.
