Adecuaci?n de la higiene prequir?rgica de manos en un hospital universitario de Madrid

BACKGROUND // We know the importance of hand hygiene in the prevention of healthcare-associated infections. However, its compliance is still a challenge. Moreover, when it is complied with, as in the case of preoperative hygiene, there are few studies on the proper performance of the technique. The aim of this paper is to assess adequacy of pre-surgical hand hygiene in operating room staff of different surgical specialities at a university teaching hospital in Madrid. METHODS // A cross-sectional study was made. Adequacy of pre-surgical hand hygiene was assessed in operating room staff of the different specialities and professional categories by direct covert observation. It was evaluated in 852 opportunities during the months of October, November and December 2020. A specific form was designed for data collection, following the recommendations of the World Health Organisation (WHO). Adequacy was described with frequency distributions of the different groups observed. Whether Chi-square or Fisher's exact tests were used to compare the different categories. RESULTS // Pre-surgical hand hygiene opportunities were evaluated, 75.5% in surgeons and 24.5% in nurses. Overall compliance with pre-surgical hand hygiene technique was 80.5 % (686). The most frequent surgical service evaluated was General Surgery with 240 observations. The professional category with the best adequacy was nursing (86.1%) and the surgical service one was Traumatology (90.2%). An stopwatch was used by some 25.8% of the evaluated professionals, with an adequate hygiene time of 96,8% (p<0,05) for that group. CONCLUSIONS // The overall adequacy of pre-surgical hand hygiene in the operating room professionals is high. Significant statis-tically differences in adequacy are found between professional categories and surgical specialities, with better compliance in nursing staff and in Traumatology. Better results are achieved by the use of an stopwatch.
