Background: Few point prevalence surveys (PPS) have been conducted in Vietnam on SSIs or antimicrobial use in surgery. We performed PPSs of surgical site infection (SSI) before and after antibiotic stewardship programs (ASP) and infection control (IC) in a Vietnamese tertiary-care hospital. --- Method: ASP and IC practices were implemented in operating rooms and the orthopedic department including antibiotic training, skin preparation, hand hygiene, gloves and sterile instruments, and SSIs risk factors. A PPS of SSIs and AMS was performed in January 2016 according to Center Disease Control methods, before ASP and IC, and in December 2019. Information recorded included surgical, antibiotic prophylaxis, microorganisms and SSI risk factors. Skin preparation compliance assessed preoperative washing and antisepsis. --- Results: SSI prevalence was 7.8% in 2016 versus 5.4% in 2019 (p = 0.7). Significant differences were found for diabetes mellitus, NNIS score, scheduled surgery and prophylactic antibiotics. A third-generation cephalosporin was prescribed more than 48 hours after surgery for most patients in both periods. Skin preparation compliance increased from 54.4–70.5% between assessments. --- Conclusions: The decreased SSI, although non-statistically significant, warrants continuing this program. Vietnamese hospital must provide comprehensive IC education to healthcare-workers addressing standard precautions and establish IC policies.
