BACKGROUND: Hand hygiene (HH) is one of the most important measures to prevent healthcare‐associated infections. Data on HH compliance in companion animal veterinary institutions in Europe are sparse. METHODS: This observational study assessed HH according to WHO standards in three large and two medium‐sized clinics and two primary care practices in Switzerland. Associations with HH indication, professional group, clinical area and institution were determined using a generalized linear mixed effects model. RESULTS: Based on 2056 observations, overall HH compliance [95% confidence interval] was 32% [30%–34%]. HH compliance was highest in the consultation area (41% [38%–45%]) and after contact to body fluids (45% [40%–50%]), and lowest in the pre‐OR area (20% [15%–24%]) and before clean/aseptic procedures (12% [9%–15%]). Veterinarians showed a higher HH compliance (37% [34%–40%]) than veterinary nurses (25% [22%–28%]). HH compliance was lower before clean/aseptic procedures compared to all other indications (all p < 0.015 except ‘before touching a patient’ in medium‐sized clinics/practices, p = 0.095) and higher in the consultation area compared to all other areas in large clinics (all p < 0.04). CONCLUSION: Effective HH training should urgently be promoted for all veterinary personnel with special emphasis on the importance of HH before clean/aseptic procedures.
