Background:
The Hand Hygiene Liaison Group and Epic Projects (Pratt et al., J Hosp Infect 47[Suppl A], 2001) have asked specifically for further trials of educational interventions to improve hand decontamination compliance and infection control in the hospital setting. This study investigates the efficacy of a 'clean practice protocol' (CPP), derived from international guidelines, to improve compliance of infection-control practices by surgical teams in a large UK teaching hospital.
Methods:
The key infection-control activities were summated to form the CPP presented here. An undisclosed infection-control audit of consultant-led ward-rounds from breast, gastrointestinal, vascular, urological, and intensive care departments was performed. The audit results were presented to the surgical teams, after which an education/awareness program was implemented. A repeat undisclosed audit was performed 3 months later. In both audits, infection-control activities were recorded together with consultation time and any patient infective complications.
Results:
The surgical teams performed as follows in the initial audit: hand decontamination (28% of consultations), correct use of gloves (2%), instrument cleaning (0%), garment contamination (49%), and notes contamination (34%). Introduction of the CPP education program significantly improved hand decontamination to 87% (p < 0.0001), the correct use of gloves/aprons to 50% (p < 0.0001), and overall infection-control practice from 63% to 89% (p < 0.05).
Conclusions:
The introduction of the CPP significantly improved compliance of hand decontamination, correct usage of gloves and aprons, and overall infection-control in a large teaching hospital. The CPP is a highly effective auditing and educational tool that can be readily adapted for use in hospitals globally to monitor and improve infection-control practices.

The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...
