Predictive factors for early hospital readmission and 1-year mortality in elder patients following surgical treatment of a hip fracture; [Cerrahi olarak tedavi edilmiş ileri yaş kalça kırığı hastalarında taburculuk sonrası erken dönem hastane başvurusu ve bir yıllık mortalitenin belirleyici faktörleri]

BACKGROUND: Early hospital readmission after surgically treated hip fracture is a common entity, often involving an adverse event and causing strains on an already overburdened healthcare system. The main purposes of the present study were to determine the 30-day readmission rate, analyze the predictive factors for early hospital readmissions, and assess 1-year mortality following surgical treatment of hip fracture in elderly patients. Retrospective case-control study. METHODS: In total, 517 patients with a mean age of 74 years were evaluated. The rate of early readmission, age, gender, body mass index, fracture type, pre-fracture mobility status, preoperative time to surgery, American Society of Anesthesiologists score, implant type, postoperative intensive care unit stay, total length of postoperative hospital stay, comorbidities, and the main reasons for readmission were the criteria for data collection. Multivariate analysis was performed to determine the main predictors of early hospital readmission. Mortality within the first year after surgery was also assessed. RESULTS: A higher prevalence of chronic obstructive pulmonary disease, cardiac arrhythmia or ischemic heart disease, diabetes, and dementia or Parkinson’s disease was detected in readmitted patients. Advanced age, American Society of Anesthesiologists (ASA) grade ≥3, postoperative intensive care unit (ICU) stay, and pre-existing cardiac arrhythmia or ischemic heart disease were identified as the main predictors. The 1-year mortality rate for the readmitted group was 53.9%, whereas it was 24% for those patients who were not readmitted. CONCLUSION: The readmission rate following surgical treatment of hip fracture in elder patients was 12%, and its main predictive factors were advanced age, ASA grade ≥3, postoperative ICU stay, and pre-existing cardiac arrhythmia or ischemic heart disease. Hospital readmission within the first 30-day period following initial discharge was significantly correlated with an increased 1-year mortality rate. © 2017 TJTES.
