Objective To compare preventive effect between continuous dissecting suture and traditional interrupted suture, silver ion dressing and traditional dressing, on the incisional surgical site infection (SSI) after ostomy for colorectal surgery, and to explore the influencing factors of SSI. Methods ① Sixty patients underwent the firstly elective open ostomy for colorectal surgery, who were treated in Department of Colorectal Tumor Surgery and Department of Colorectal&Hernial Minimally Invasive Surgery of Shengjing Hospital from Mar. 2015 to Jan. 2016, were collected to equivalently divided into continuous dissecting suture group and traditional interrupted suture group randomly. ② Twenty-seven patients with emergency open ostomy for colorectal surgery, who were treated in Department of Colorectal Tumor Surgery and Department of Colorectal&Hernial Minimally Invasive Surgery of Shengjing Hospital from Jan. 2009 to Jun. 2015, as well as 33 patients with elective open ostomy for colorectal surgery, who were treated in the same 2 Departments from Jul. 2015 to May. 2016, were collected to equivalently divided into silver ion dressing group and traditional dressing group. ③ Clinical data of 184 patients with elective open ostomy for colorectal surgery who were treated in Department of Colorectal Tumor Surgery and Department of Colorectal&Hernial Minimally Invasive Surgery of Shengjing Hospital from Jan. 2009 to May. 2016 were collected to analyze the influencing factors of SSI after elective open ostomy for colorectal surgery. Results ① There was no significant difference in the incidence of SSI between continuous dissecting suture group (3.3%, 1/30) and traditional interrupted suture group (16.7%, 5/30), P=0.085. ② The incidence of SSI in silver ion dressing group (6.7%, 2/30) was significantly lower than that of traditional dressing group (30.0%, 9/30), P=0.020. ③ There were 28 patients (15.2%) of the 184 elective patients and 11 patients (40.7%) of the 27 emergency patients suffered from SSI after open ostomy for colorectal surgery, and the incidence of SSI in elective surgery group was lower than that of emergency surgery group (P=0.001). ④ Results of logistic regression model showed that, patients with body mass index (BMI) <25 kg/m2 had lower risk of SSI than patients with BMI≥25 kg/m2(OR=0.383, P=0.023), patients received permanent colostomy had higher risk of SSI than patients received protective ileostomy (OR=4.370, P=0.004), patients underwent Mile’s surgery had higher risk of SSI than patients received distal anastomosis (OR=4.406, P=0.005). Conclusions The ostomy is a high risk factor for incisional SSI after elective open ostomy for colorectal surgery, especially for the obesity patients and patients who receive colostomy. The using of silver ion dressing play an important role in preventing the incisional SSI.
ObjectiveTo review the research on the reasons of unplanned reoperation (URP) for degenerative lumbar spine diseases, and to provide new ideas for improving the quality of surgery for degenerative lumbar spine diseases. Methods The literature about the URP of degenerative lumbar spine diseases at home and abroad in recent years was reviewed and analyzed. Results At present, the reasons for URP include surgical site infection (SSI), hematoma formation, cerebrospinal fluid leakage (CSFL), poor results of surgery, and implant complications. SSI and hematoma formation are the most common causes of URP, which happen in a short time after surgery; CSFL also occurs shortly after surgery but is relatively rare. Poor surgical results and implant complications occurred for a long time after surgery. Factors such as primary disease and surgical procedures have an important impact on the incidence of URP. ConclusionThe main reasons for URP are different in various periods after lumbar spine surgery. Interventions should be given to patients with high-risk URP, which thus can reduce the incidence of URP and improve the surgery quality and patients’ satisfaction.
Objective To analyze the trend of standardized infection ratio (SIR) of surgical site infection (SSI) in small bowel surgery, objectively evaluate the effect of infection control, and provide evidence-based strategies for SSI prevention. Methods According to Centers for Disease Control and Prevention (CDC) / National Healthcare Safety Network (NHSN) surveillance definitions for specific types of infections and the monitoring methods of SSI events published by NHSN, the SSI and related risk factors of adult inpatients undergoing small bowel surgery in Yichang Central People’s Hospital between January 1, 2016 and December 31, 2022 were prospectively monitored. The inpatients undergoing small bowel surgery that meets the definition of International Classification of Diseases, 10th Revision Clinical Modifications/Procedure Coding System (ICD-10-CM/PCS), a multivariate binary logistic regression model was used to calculate the predicted infections in each year, the model included the risk factors for small bowel surgery in NHSN Complex Admission/Readmission (A/R) SSI Model with 7 years of surveillance data as the baseline. The SIR was calculated by dividing the number of observed SSI by the number of predicted SSI in each year. The Mid-P method was used to test the difference of SIR compared to the previous year, and the linear regression model was used to analyze the trend of SIR. Results A total of 2 436 patients were included, with 48 cases of deep incision infection and 49 cases of organ/cavity infection, and the overall incidence rate of infection was 4.0%. From 2016 to 2022, there were 151, 244, 222, 260, 320, 408, and 831 patients who underwent small bowel surgery, respectively. The Mid-P test showed that there was a significant difference in SIR from 2016 to 2019 (P<0.05), and there was an increase in 2018 compared with 2017. There was no significant difference in SIR compared to the previous year from 2019 to 2022 (P>0.05), and there was no significant difference in the trend of SIR of SSI (P=0.065). Conclusions From January 1, 2017, to December 31, 2022, advances have been made in SSI control practices of small bowel surgery in six consecutive years, except for 2018, but there was no annual downward trend from 2020 to 2022. The use of SIR provides a new approach for evaluating the quality of infection control.
Objective To explore the application methods and values of using health failure mode and effect analysis (HFMEA) to prevent surgical site infection (SSI) in patients undergoing bone fracture and craniotomy surgery with class Ⅰ incision. Methods Patients undergoing bone fracture and craniotomy surgery with class Ⅰ incision at the Chengdu Pidu District People’s Hospital between January 2020 to December 2021 were selected. Based on whether receiving HFMEA-based risk management or not, the patients were divided into conventional group and intervention group. The compliance rates with infection control measures, changes in risk priority numbers (RPN) at various stages (1 month and 10 months after intervention) of HFMEA implementation, and the incidence of SSI between the conventional group and the intervention group were compared. Results A total of 884 surgeries were included. Among them, there were 399 cases in the conventional group and 485 cases in the intervention group; 16 cases SSI occurred. A total of 7 SSI prevention and control measures had been formulated. Except for proper surgical attire (P＞0.05), there were statistically significant differences in the compliance rate of the other prevention and control measures between the two groups of patients (P＜0.05). In the intervention group, the RPN values of pre-operative, intra-operative, and post-operative risk factors at the 10th month after intervention were all lower than those at the 1st month after intervention (P<0.05). Except for the incidence of SSI during craniotomy surgery (6.1% vs. 1.8%, P=0.375), there were statistically significant differences in the total SSI incidence (3.3% vs. 0.6%) and bone fracture surgery SSI incidence (2.7% vs. 0.5%) between the conventional group and the intervention group (P>0.05). Conclusion Applying HFMEA-based risk management techniques to prospectively identify, assess, analyze, manage and track the risk of SSI in bone fracture and craniotomy surgery with class Ⅰ incision can effectively enhance the adherence of preventive measures and reduce the incidence rate of SSI.
