Rapid Response:

Evidence for handwashing for the GPs

Dear Editor,

Jefferson and colleagues concluded from their systematic review that
handwashing and other simple physical interventions could reduce the
transmission of epidemic respiratory viruses.1 Both the previous2 and
current reviews included studies conducted in the community and hospital
settings but none at the primary care level. During the epidemic of severe
acute respiratory syndrome (SARS), eight primary care doctors (including
one dentist) and at least one family member of these doctors contracted
SARS with two subsequent deaths in Hong Kong.3 Another review which
focussed on evidence related to hand hygiene for general practitioners
identified four randomised control trials using gastrointestinal outcomes
such as diarrhoea as outcome measures and none on respiratory illness or
symptoms.4 Given the epidemiology, pathogens, length of contact and
severity of respiratory infections are different in a primary care context
than in the hospital and community setting, further evidence is urgently
required if the frontline practising doctors are to be convinced.
