Abstract:
Objective:To explore the risk factors of pinhole infection in patients with external fixators, and build a risk prediction model.Methods:From January 2018 to June 2019, the data of patients ( n=300) with external fixators in the Department of Trauma and Orthopedics, South Hospital, South Medical University, were selected by retrospective survey, and were divided into infection group and non-infection group according to whether pinhole infection occurred in the postoperative case records. Single factor analysis and Logistic regression analysis were used to establish the risk factors of pinhole infection and its prediction model. The grade of risk prediction was constructed by the assignment method. Results:Among 300 patients with external fixators, 103 (34.33%) had pinhole infection and 197 (65.67%) had no infection. Logistic regression analysis showed that basic disease [ OR=4.726 (one of diabetes, pulmonary infection), 17.053 (two of diabetes, pulmonary infection, cardiovascular diseases) ], postoperative albumin [ OR=0.082 (<25 g/L) ], postoperative hemoglobin [ OR=3.715 (>90-120 g/L), 9.720 (>60-90 g/L), 7.338 (30~60 g/L) ], intraoperative bleeding volume [ OR=2.196 (200-400 ml), OR=3.256 (>400 ml) ] and the type of disinfectant [ OR=3.897 (chlorhexidine), 3.625 (iodophor + chlorhexidine) ] were risk factors for pinhole infection in patients with external fixators ( P<0.05). The constructed model was divided into high-risk group (≥ 7 points), higher-risk group (5-6 points), medium-risk group (4 points), low-risk group (3 points) and lower-risk group (0-2 points) . Conclusions:The model can well predict the risk of pinhole infection of orthopedic external fixator, provide reference for medical and nursing staff to identify the risk of external fixation infection in time, and prevent the occurrence of infection as soon as possible.
