Evaluation of current practices in surgical antimicrobial prophylaxis in primary total hip prosthesis--a multicentre survey in private and public French hospitals.
Deep wound infection is a rare but dreaded postoperative complication after total hip prosthesis (THP) procedures but its incidence can be reduced by systemic antimicrobial prophylaxis. The objective of the present study was to evaluate whether antimicrobial prophylaxis for elective primary THP in patients without any history of hip infection, in orthopaedic wards, participating on a voluntary basis, in French public hospitals and private institutions, complies with published guidelines. Three types of data were collected from anaesthetic and surgical records (November 2000-January 2001) in participating hospitals: (1) administrative data on the hospitals and orthopaedic wards, (2) data on patients, (3) data on compliance of practices with five critical criteria derived from published French guidelines. These criteria concerned administration of prophylaxis, choice of antimicrobial agent, dose of first injection, timing of administration and total length of prophylaxis. Thirty institutions sent data files on 1257 THPs to the coordination centre. Compliance exceeded 80% for all criteria except one (interval between first and second injection). Cumulative compliance with the five criteria was 66.9%. Major compliance failures were an inappropriate interval between the first injection and incision, and total antimicrobial prophylaxis exceeding 48 h. Cumulative compliance was 87.9% in teaching hospitals, 61.8% in general hospitals and 67.7% in private institutions (P<1 x 10(-6)). It was slightly higher when the annual number of interventions was > or =100 (69.4 versus 62.3%; P<0.02). Although the protocol for antimicrobial prophylaxis in THP was clear and easy, one-third of practices did not conform with all five standards. Knowledge of the results by the participating institutions should encourage them to set up working groups to draft care protocols for THP and other surgical interventions, in order to improve practice and perhaps reduce costs.
