ABSTRACT
BACKGROUND: A preoperative, in-community antimicrobial decolonization protocol combining chlorohexidine gluconate (CHG) sponges and mupirocin ointment to reduce surgical site infections amongst hip and knee replacement patients has been adopted in Alberta, Canada. Patient compliance with the protocol is essential for effectiveness. It is, therefore, important to understand patterns, and reasons why, patients do, and do not, comply. METHODS: A descriptive survey of patients having elective total hip or knee replacement at seven clinics in Alberta was conducted to determine patient compliance and reasons for noncompliance. Descriptive statistics and multivariate logistic regression were computed. RESULTS: Patient compliance was assessed in 3,427 patients. There were no differences in compliance based on the baseline protocols and enhanced protocols, but there was a difference based on clinic location. The odds of compliance with three CHG sponges were 4.47 times higher in rural versus urban clinics (P < .001). The most common reason for noncompliance for patients instructed to use 3 CHG sponges was "patient forgot". CONCLUSIONS: Compliance did not change when enhanced protocols were introduced; however, compliance differed by clinic location. Reasons for noncompliance included "sponges not provided", "patient forgot", and "surgery date moved". Results may inform clinics on areas where improvements could be made to increase patient compliance.
