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

Area of Science:

• Orthopedics
• Geriatric Medicine
• Health Services Research

Background:

• Hip fractures are a common cause of hospitalization, particularly in older adults.
• Readmission after hip fracture surgery poses significant healthcare burdens and impacts patient outcomes.
• Identifying modifiable risk factors for readmission is crucial for improving post-operative care.

Purpose of the Study:

• To investigate known and novel risk factors for 30-day hospital readmission following hip fracture.
• To analyze the association between patient demographics, comorbidities, and discharge disposition with readmission rates.
• To identify specific patient subgroups requiring focused post-discharge management.

Main Methods:

• Utilized the Cerner Health Facts Electronic Health Record database (January-August 2015).
• Employed univariate analyses (Chi-square or Fisher exact test) to assess individual variable associations with readmission.
• Developed a multivariate logistic regression model to identify independent predictors of 30-day readmission.

Main Results:

• The study cohort comprised 34,790 admissions from 33,740 unique patients.
• The overall 30-day readmission rate for hip fracture patients was 10.7%.
• A significant novel finding was that patients with prior inpatient or emergency visits within the past year had a higher likelihood of 30-day readmission (P < 0.001).

Conclusions:

• Patients with a history of recent hospitalizations (inpatient/emergency visits) represent a high-risk group for 30-day readmission after hip fracture.
• Discharge to a location other than home is also associated with increased readmission risk.
• Targeted interventions and optimized care pathways for these high-risk patients are essential to reduce readmission rates.
