Promotion of hand hygiene: the experience of the orthopaedic hospital Gaetano Pini-CTO, Milan, Italy.

BACKGROUND: Hand hygiene is the primary preventive measure against health care-associated infections in terms of cost-effectiveness. In 2005, the WHO proposed the "Global Patient Safety Challenge" campaign, with the aim of reducing the overall incidence of such infections, through multimodal programs and strategies, interactive training tools and standardised methods for monitoring compliance.

STUDY DESIGN: On the basis of project "Rimani", sponsored by the Health and Social Care Authority of Emilia-Romagna, the Istituto Ortopedico Gaetano Pini has implemented a project which seeks to increase healthcare staff's compliance with hand hygiene.

METHODS: A multidisciplinary working group was created to prepare the project documents. Starting from 5th April 2015, twenty operational units were asked to produce information and training material. On 5th May, during a conference, a committee selected the three best works. The material was distributed on a monthly basis to the various departments. In addition to the training, the specifically trained operators of the Medical Monitoring Department carried out direct hand washing tests, filling out appropriate checklists. Non-compliance relating to the technique recorded in 2014 and 2015 was compared and a statistical analysis was conducted using Student's t-test for paired data.

RESULTS: Three tests were carried out in 2014. Ninety-nine cases were monitored and 5 non-compliance cases were reported, concerning the execution of the procedural steps, the running time and closing the tap with one's hands at the end of the wash. In 2015 two tests, involving 30 operational units, were carried out. 60 observations were performed, and no non-conformities emerged concerning the technique. Statistical analysis showed a significant reduction of non-compliances between the 2014 and 2015 P = 0.000).

CONCLUSION: The results obtained agree with the main findings in literature. The comparison between the 2014 and 2015 tests shows a trend of improvement in the wash technique. This confirms the effectiveness of a multidisciplinary approach and recognises the active and participatory involvement suggested by the WHO.
