Readmission Rates After Hip Fracture: Are There Prefracture Warning Signs for Patients Most at Risk of Readmission?

This is the authors' abstract. We don't add key points for this paper.

BACKGROUND: The purpose of this study was to evaluate known and yet unknown risk factors associated with readmission to the hospital within 30 days after hip fracture. METHODS: In this study, we used the Cerner Health Facts Electronic Health Record database data from January to August 2015. The univariate association of each variable (discharge location, demographic details, and comorbidities) against the 30-day readmission status was evaluated using the Chi-square test or the Fisher exact test. The significant variables (P < 0.05) obtained by the univariate analysis were used to build the multivariate logistic regression model to evaluate the multivariate associations of the variables. RESULTS: Thirty-four thousand seven hundred ninety index admissions of 33,740 unique patients were included in the study cohort. The overall 30-day readmission rate for patients with hip fractures was 10.7%. We demonstrated a new variable not discussed in previous articles on this topic: patients with previous inpatient/emergency visits within the past year were more likely to be readmitted within 30 days after the hip fracture surgery (P < 0.001). CONCLUSION: For patients with hip fractures, particular efforts should be taken to optimize outcomes in those with recent hospitalizations and/or discharge to a location other than home.

Prior hospitalizations associated with higher 30-day readmission after hip fracture; leaves open whether targeted interventions reduce risk.
