Relationship of Exercise and Hospital Readmission After Spinal Cord Injury: A Secondary Analysis

Importance: After spinal cord injury (SCI), as many as 45% of people experience at least one hospital readmission within 1 yr. Identification of feasible low-cost interventions to reduce hospital readmissions after SCI is needed. Objective: To explore whether a relationship exists between routine exercise and hospital readmission rates 1 yr after SCI. Design: We conducted a secondary analysis of data from the SCIRehab Project, a prospective cohort study. Setting: Five SCI inpatient rehabilitation facilities across the United States. Participants: Participants were people age 12 yr and older who had sustained an SCI, were admitted to a participating inpatient rehabilitation facility, completed the 12-mo postinjury interview, and reported exercising either monthly or not at all since discharge (N 5 520). Outcomes and Measures: The SCIRehab Project conducted 12-mo postinpatient rehabilitation discharge interviews. As part of the interviews, self-reported hospital readmissions and exercise frequencies since discharge (self-reported number of months, average days per week, and average minutes per day of exercise participation) were collected and analyzed. Results: A v² analysis determined that a significant correlation (u 5 ̶.091, p 5 .038) exists between monthly exercise and hospital readmissions 1 yr postinjury. Compared with those who did not exercise, participants who exercised monthly had 8.4% fewer hospital readmissions. Conclusions and Relevance: A relationship exists between exercise and hospital readmission, but follow-up research is needed to determine whether regular exercise reduces hospital readmissions among this population.
