An evaluation of the training module of an interactive infection control co
mputer-assisted learning (CAL) software program was carried out with ward-b
ased nurses, third-year medical students and infection control personnel. A
ll nursing staff, 87% of the medical students and all infection control sta
ff found the programme easy and enjoyable to use. The module was accessed 3
101 times on the hospital network in 18 months with usage settling to betwe
en 100-150 times per month. There was a higher level of use by night-duty a
nd weekend staff. Medical students gained as much infection control knowled
ge from using the CAL package (increase in correct responses from 63.5% to
83.4%; P<0.0001) as they did from a formal lecture (increase in correct res
ponses from 62.1% to 79.5%; P<0.0001). We conclude the training module whic
h is accessible on the hospital wards and across the academic network, is a
convenient and effective way for staff and students to gain a basic unders
tanding in evidence-based infection control practices, at locations and tim
es suitable for them. (C) 2000 The Hospital Infection Society.
