Background: in older patients, there is a high risk of hospital readmission within the first year after surgery for hip fracture, due to complications following treatment or to the evolution of prior comorbid conditions.
Objectives: to identify factors associated with readmissions related to the index surgical stay.
Design: retrospective cohort study.
Setting: administrative claims databases.
Subjects: patients over 75 surgically treated for hip fracture in Paris area.
Methods: we analysed all admissions in 2005, and tracked for 1-year readmissions. First readmissions (FRs) were classified as related or unrelated to the index stay, according to rules defined a priori. We analysed the association between patient characteristics and the FR.
Results: among 5,709 patients, 32% had at least one readmission, 53% were FR related. Near 80% of related readmissions occurred within 3 months from discharge. Surgical conditions caused 47% of all related readmissions, and male gender, dementia, cancer or kidney diseases were independent risks factors.
Conclusions: half of readmissions could be classified as related to the index stay and a great majority of these occurred early post discharge. Surgical conditions caused 47% of all related readmissions. Improvement in orthopedic-geriatric co-care is suitable to expect an impact on outcomes after surgery.
