Objective: To investigate the factors affecting early postoperative hospital-acquired infections in patients undergoing spinal surgery and the nursing countermeasures.
Methods: A total of 454 patients who underwent spinal surgery in our hospital from July 2017 to June 2021 were selected for the study. The probability of infection in patients was recorded. The sites of infection and the distribution of pathogenic bacteria were also analyzed. The risk factors for infection in patients were analyzed unifactorally and multifactorally to develop appropriate and effective nursing countermeasures.
Results: Of the 454 patients undergoing spinal surgery, 34 patients exhibited symptoms of infection, with an incidence of infection of 7.49%. Pulmonary infections were the highest proportion of these, accounting for 46.94% of all infected patients and 3.52% of all patients. There was no statistically significant difference in the incidence of early postoperative hospital-acquired infections between patients of different genders (p>0.05). The differences in early postoperative hospital infection rates among patients with different ages, length of stay, intraoperative placement materials, comorbid diabetes mellitus, indwelling catheters, and time of surgery were statistically significant (P>0.05). Multi-factor logistic regression analysis showed that age, length of stay, intraoperative placement material, comorbid diabetes, indwelling catheter, and time of surgery were the main factors affecting early postoperative hospital-acquired infections in patients undergoing spinal surgery (p<0.05).
Conclusion: Patient age, length of stay, intraoperative placement of materials, combined diabetes, indwelling catheters, and time of surgery are factors that influence postoperative infections in patients undergoing spinal surgery. Therefore, early postoperative hospital infections in patients undergoing spinal surgery should be avoided through preoperative assessment of patients, early removal of catheters, scientific adjustment of the application of antibacterial drugs, appropriate postoperative exercise interventions, and improvement of nursing staff's operational skills.
