| Abstract: | BackgroundThe purpose of this study was to compare outcomes after hip fracture surgery between DNR/DNI and full code cohorts to determine whether DNR/DNI status is an independent predictor of complications and mortality within one year. A significant number of geriatric hip fracture patients carry a code status designation of DNR/DNI (Do-Not-Resuscitate/Do-Not-Intubate). There is limited data addressing how this designation may influence prognosis.MethodsA retrospective chart review of all geriatric hip fractures treated between 2002 and 2017 at a single level-I academic trauma center was performed. 434 patients were eligible for this study with 209 in the DNR/DNI cohort and 225 in the full code cohort. The independent variable was code-status and dependent variables included patient demographics, surgery performed, American Society of Anesthesiologists, score, Charlson Comorbidity Index, significant medical and surgical complications within one year of surgery, duration of follow-up by an orthopaedic surgeon, duration of follow-up by any physician, and mortality within 1 year of surgery. One-year complication rates were compared, and multiple logistic regression analyses were performed to analyze the relationship between independent and dependent variables.ResultsThe DNR/DNI cohort experienced significantly more surgical complications compared to the full code cohort (14.8% vs 7.6%, p = 0.024). There was a significantly higher rate of medical complications and mortality in the DNR/DNI cohort (57.9% vs 36%, p < 0.001 and 19.1% vs 3.1%, p = 0.037, respectively). In the regression analysis, DNR/DNI status was an independent predictor of a medical complication (odds ratio 2.33, p = 0.004) and one-year mortality (odds ratio 9.69, p < 0.001), but was not for a surgical complication (OR 1.95, p = 0.892).ConclusionsIn our analysis, DNR/DNI code status was an independent risk factor for postoperative medical complications and mortality within one year following hip fracture surgery. The results of our study highlight the need to recognize the relationship between DNR/DNI designation and medical frailty when treating hip fractures in the elderly population. |
