Analysis on influencing factors of perioperative nosocomial infection in elderly patients with hip fracture under the background of enhance recovery after surgery / 中国实用护理杂志

ABSTRACT

Objective:To analyze the influencing factors of perioperative nosocomial infection in elderly patients with hip fracture under the background of enhance recovery after surgery so as to provide guidance for prevention and control of the nosocomial infection.Methods:The clinical data were collected from 1 628 elderly patients with hip fracture who were hospitalized from January 2018 to August 2019,during the implementation of enhance recovery after surgery in Tianjin hospital. Medical records of the patients were reviewed and statistically analyzed through hospital medical record system, the incidence of perioperative nosocomial infection and the influencing factors for the infection were observed.Results:Of the 1 628 hospitalized patients with hip fracture, 102 had nosocomial infection, 125 case-times, with the infection rate 6.27%(102/1 628) and the case-times infection rate 7.68%(125/1 628). Lower respiratory tract, urinary tract and surgical site were the dominant infection sites, accounting for 72.80% (91/125), 11.20% (14/125) and 10.40% (13/125) respectively. Univariate analysis and multivariate logistic regression analysis indicated that bone traction( OR value was 2.152, 95% CI 1.130-4.097), surgery ( OR value was 0.268, 95% CI 0.133-0.537), hospitalization days≥15 d( OR value was 12.123, 95% CI 6.017-24.426), indwelling urinary catheter ( OR value was 7.566, 95% CI 4.093-13.986), cardiac insufficiency( OR value was 2.112, 95% CI 1.192-3.740), electrolyte disturbance( OR value was 2.383, 95% CI 1.396-4.067), lower extremity arteriosclerosis obliterans( OR value was 2.540, 95% CI 1.279-5.045) and senile dementia( OR value was 3.673, 95% CI 1.670-8.082) were the influencing factors for the perioperative nosocomial infection. Conclusions:The main influencing factors of nosocomial infection in elderly patients with hip fracture during the perioperative period were bone traction, operation, length of stay, indwelling urinary catheter and coexisting diseases. The risk of nosocomial infection can be reduced by applying the concept of enhance recovery after surgery in clinical orthopedics, comprehensively optimizing perioperative management and implementing effective prevention and control measures of nosocomial infection.
