Increasing handwashing in healthcare workers

Comment

Washing hands to reduce hospital acquired infection ( Bandolier 73 ) is an important topic examined before ( Bandolier 67 , 82 ). Just to remind ourselves, in the UK hospital acquired infection costs about £1 billion a year, affects 1 patient in 10 in hospital, is responsible for the deaths of many more people than are road accidents, and use the resources of about 27 400-bed hospitals. And that's just the broad picture. At the margins, the effects on healthcare under pressure, as during Winter crises, the effects are much more than these stark assessments.

There's precious little around on handwashing that is easy to find, so when a systematic review about how to increase handwashing in healthcare workers [1] hoves into view it deserves some attention.

Review


The search was through, using four databases, searching the Internet, examining reference lists and attempting to identify unpublished work. Any study that aimed to promote handwashing in healthcare workers as a hospital infection control measure was included. Nearly 3000 citations were identified and examined.

Results


There were 21 studies fulfilling the inclusion criteria. Seventeen were uncontrolled studies and only two were randomised studies. Almost all (20/21) used observation to assess compliance with handwashing.

Handwashing - main themes



The results of the studies are summarised in the box. Clearly it is the multifaceted approach that does best, as the recent example from Geneva ( Bandolier 82 , not included in this review) showed.

Comment


It is remarkable, given the importance of hospital acquired infection, that more attention has not been given to studies of hand decontamination, so that we know what to do for the best to minimise this important problem. This review is an excellent start for those wanting to reduce our (and their) ignorance. None mentions water at over 60°C without mixer taps, or any other positive barriers to handwashing.

In decent studies ( Bandolier 67 , 82 ) good handwashing initiatives can cut hospital acquired infections by about half. That is a big effect in a big problem. This review will benefit all those in secondary (and primary) care who want to deliver a safer and better service.
