Handwashing is simple, cost-effective and the single most important measure in the prevention of transmission of multiple antibiotic-resistant bacteria, which can spread via the contaminated hands of healthcare workers (HCWs) in intensive care units (ICUs). Despite this simplicity and efficacy, compliance with handwashing protocols is unsatisfactory among HCWs in ICUs. No single interventional measure is successful in improving handwashing compliance.

A continuous educational program was started in February 1998 by the department of infection control, emphasising the importance of handwashing in the prevention of nosocomial infections in the ICU. It took the form of posters, lectures and regular discussions. The posters were pasted in all the strategic areas of the ICU, displaying the indications and precise technique of handwashing. HCWs were directly observed for handwashing compliance, while working in the ICU. Each indication of handwashing was counted as an opportunity of handwashing.

Assessment of handwashing compliance was made once a year during the educational programme. In the final annual assessment in February 2002, out of 1,175 opportunities of handwashing, compliance was observed in 856 (72.8%) among all categories of staff. Highest compliance of 97.5% was recorded among nurses. The compliance among technicians was 47.7%, while the lowest compliance of 37.6% was observed among doctors (RR 2.591, p<0.0001). Opportunities of handwashing utilised with good technique were observed among 98.2% nurses. Handwashing compliance among females was significantly higher (76.2% versus 23.8%) than the male HCWs (RR 3.196, p<0.0001).

A comparative study of the yearly assessments made since the start of the educational program also revealed significant increases in handwashing compliance among nurses (p<0.0001) and technicians (p<0.001), while no statistically significant changes in the handwashing behaviour among doctors was observed during the study period (February 1998 to February 2002).

Disappointing handwashing compliance among doctors visiting and working in the ICU, despite their better understanding of hospital-acquired infections (HAI) and continuous educational programme remains a cause for concern. Additional efforts are required to discover more effective interventional measures to improve handwashing compliance among doctors.
