Effect of a Standardized Protocol of Antibiotic Therapy on Surgical Site Infection after Laparoscopic Surgery for Complicated Appendicitis

Antibiotic therapy in pediatric acute appendicitis: Compliance with local protocol to reduce antibiotic overuse

PURPOSE

Acute appendicitis is one of the commonest surgical emergencies in pediatrics. Treatment usually consists of a combination of surgery and antibiotics. The present study was designed to assess compliance with our local antibiotic protocol and analyse the consequences of non-compliance.

METHODS

Children presenting with acute appendicitis between 2015 and 2017 were included in this study. The diagnosis of acute appendicitis was confirmed during surgery. Data concerning the antibiotic therapy received and infectious complications were reviewed.

RESULTS

A total of 142 children with acute appendicitis were included. Antibiotic therapy complied with the protocol in 27.4% of cases, while an excessive duration of antibiotic therapy was observed in 65% of cases. A total of 270 days of non-recommended antibiotic therapy was noted; 32% of patients received a non-recommended combination of antibiotics. The infectious complications rate was 12.8% in the group of patients receiving appropriate antibiotic therapy, and 11.6% in the group with non-compliance to the protocol. No statistically significant difference between the groups was found (P=0.85).

CONCLUSION

Poor compliance with the antibiotic guidelines for appendicitis resulted in antibiotic overuse with no benefit in terms of anti-infective efficacy. Better information for the medical team and repeated evaluation of our practices are essential.

Surgical Site Infection After Gastrointestinal Surgery in China: A Multicenter Prospective Study

BACKGROUND

There is no nationwide database of information on surgical site infection (SSI) after gastrointestinal surgery in China. This study aimed to determine the incidence of SSI after gastrointestinal surgery in China and evaluate the related risk factors.

MATERIALS AND METHODS

The multicenter, prospective, observational study enrolled adult patients who underwent gastrointestinal surgery from May 1, 2018 to June 30, 2018 in 30 hospitals in China. The demographic and perioperative characteristics were collected, and the primary outcome was 30-d SSI. Predictors of SSI were determined by multivariable logistic regressions. Subgroup analysis was performed to determine the predictors of SSI in different surgeries.

RESULTS

A total of 1290 patients were enrolled and SSI occurred in 68 patients (5.2%). Multivariate analysis with adjustments revealed that normal body mass index, normal blood glucose level, low national nosocomial infection surveillance risk index score, noncolon surgery, laparoscopic or robotic surgery, and use of mechanical bowel preparation were associated with reduced SSI in gastrointestinal surgery. Subgroup analysis revealed diverse predictors of SSI in diverse surgeries. National nosocomial infection surveillance risk index score of 2 and a high blood glucose level increased the incidence of SSI in colorectal and noncolorectal surgery, respectively. Besides, mechanical bowel preparation and laparoscopic or robotic surgery were protective factors for SSI in colorectal and noncolorectal surgery, respectively.

CONCLUSIONS

This study provides the newest data of SSI after gastrointestinal surgery in China and revealed some predictors of SSI in diverse surgeries, which can be a tool to look for areas to target quality improvement initiatives.
