Impact of Antibiotic Prophylaxis Change on Surgical Site Infections After Pancreaticoduodenectomy

Patients undergoing pancreaticoduodenectomy after preoperative biliary drainage are at increased risk of surgical site infections (SSI) due to bile colonization. Recent guidelines recommend the use of piperacillin/tazobactam instead of cephalosporins for antibiotic prophylaxis in this population. However, the relevance of this strategy may depend on local microbiological ecology. This monocentric ambispective cohort study aims to compare SSI rates between two periods: before and after implementation of piperacillin/tazobactam prophylaxis. The study also evaluates microbiological profiles of bile cultures, antibiotic susceptibility, and postoperative antibiotic exposure. The primary hypothesis is that adaptation of antibiotic prophylaxis to local ecology may optimize outcomes while limiting unnecessary exposure to broad-spectrum antibiotics.

Effectiveness of Digital Game-Based Learning in Teaching Surgical Site Infection Prevention to Nursing Students

This study aims to evaluate the effectiveness of digital game-based learning in teaching evidence-based surgical site infection prevention interventions to second-year nursing students. Using a mixed-methods randomized controlled design, students will be assigned to either a digital game-based learning group or a traditional theoretical education group. Quantitative outcomes will assess changes in students' knowledge levels and cognitive load across three measurement points (baseline, 4-week post-intervention, and 8-week follow-up). In addition, qualitative data will be collected through semi-structured interviews with students in the intervention group to explore their learning experiences and perceptions of the digital learning approach. The findings of this study are expected to contribute to evidence-based educational strategies in nursing education, particularly in the teaching of surgical site infection prevention.
