Factors affecting the incidence of surgical site infections after geriatric hip fracture surgery: a retrospective study during 2017-2020.

Abstract

Introduction: Geriatric hip fracture are a common and disruptive public health problem worldwide. Surgical Site Infection (SSI) can be a devastating complication of this injury. By identifying these factors, the adverse outcomes of elderly hip fractures can be prevented. The objective of this study was to identify factors affecting the incidence of surgical site infection after geriatric hip fracture surgery.

Methods: In this retrospective study, 440 patients (60 years or older) underwent hip surgery at Imam Khomeini Hospital Complex were selected based on census between April 2017 and March 2020. Demographics information, and additional comorbidities and operation-related variables were extracted and analyzed. Data analyses were performed by descriptive statistics and inferential statistics. SPSS-19 software was used in this study and P values less than 0.05 were considered significant.

Results: The results of univariate analyzes showed that the type of surgery (p=0.005), readmission (p=0.0001) and level of self-care (p=0.001) were significantly associated with Surgical Site Infection (SSI). The results of regression analysis showed that history of readmission and self-care at all levels on SSI.

Conclusion: The findings showed that the history of readmission and self-care at all levels is effective on SSI in the elderly with hip fractures. Therefore, it can be concluded that by identifying the factors affecting the SSI with hip fractures, fewer acute complications, reduced death and shorter length of hospital stay.
