Abstract
Objective To evaluate the factors associated with readmission within 30 days after discharge
(R30) and in-hospital mortality (IHM) in elderly patients undergoing proximal femur
fracture surgery (PFF).
Methods Retrospective cohort with data from 896 medical records of elderly (≥ 60 years) patients
submitted to PFF surgery in a Brazilian hospital between November 2014 and December,
2019. The patients included were followed-up from the date of hospitalization for
surgery up to 30 days after discharge. As independent variables, we evaluated gender,
age, marital status, pre- and postoperative hemoglobin (Hb), international normalized
ratio, time of hospitalization related to the surgery, door-surgery time, comorbidities,
previous surgeries, use of medications, and the American Society of Anesthesiologists
(ASA) score.
Results The incidence of R30 was 10.2% (95% confidence interval [CI]: 8.3–12.3%), and the
incidence of IHM was 5.7% (95%CI: 4.3–7.4%). Regarding R30, hypertension (odds ratio
[OR]: 1.71; 95%CI: 1.03–2.96), and regular use of psychotropic drugs (OR: 1.74; 95%CI:
1.12–2.72) were associated in the adjusted model. In the case of IHM, higher chances
were associated with chronic kidney disease (CKD) (OR: 5.80; 95%CI: 2.64–12.31), longer
hospitalization time (OR: 1.06; 95%CI: 1.01–1.10), and R30 (OR: 3.60; 95%CI: 1.54–7.96).
Higher preoperative Hb values were associated with a lower chance of mortality (OR:
0.73; 95%CI: 0.61–0.87).
Conclusion Findings suggest that the occurrence of these outcomes is associated with comorbidities,
medications, and Hb.
