Abstract:
Objective To explore the association between preoperative frailty and postoperative complications in elderly patients undergoing knee and hip surgeries.
Methods Three-hundred and six elderly (≥65 years) patients undergoing knee or hip surgeries were included and a prospective cohort study was performed in General Hospital of Eastern Theater Command from June 2016 to September 2019. The patients included 103 males, 203 females, aged 65-89 years, with mean age 74.5± 6.2 years. According to preoperative frailty assessment by modified frailty index (mFI), patients were divided into frail and non-frail groups. Baseline characteristics [Body mass index (BMI), ASA classification, intraoperative conditions (surgery time, blood loss), postoperative complication incidence and outcome (hospital stay, 30-day readmission)] and ROC curve were compared between the two groups.
Results This study showed that 34.3% (105/306)of patients were categorized as the frail group. The incidence of postoperative complications was 35.2% (37/105), which was significantly higher than non-frail group [16.9% (34/201)] (P<0.05). The area under ROC curve of preoperative frailty by area under ROC curve to predict postoperative complications was 0.87, with a sensitivity of 63% and specificity of 89%.
Conclusion Preoperative frailty significantly increases postoperative complication incidence in elderly patients undergoing knee and hip surgeries.
