Doctors, surgeons and hospital chefs are among the worst at hand hygiene.
Figures from the latest Health Quality and Safety Commission National Hand Hygiene report, conducted over four months, reveals medical practitioners across all district health boards had a poor rate of hand washing - 57.1 per cent. The national standard is 70 per cent.
Of the 3,416 washing opportunities for medical practitioners, only 1,952 were acted upon, the report found. The 1,464 incidents when handwashing didn't take place are considered chances for infection to spread to patients.
Student doctors' compliance was 41.7 per cent and domestic staff, including cleaners and those working with food, was 35.6 per cent.
