The Medical Defence Union has written to members to reinforce advice on dealing with the millennium computer bug. It says doctors should 'assume that anything electronic they use in their practice could become date sensitive on 1 January' and other flashpoints, including 9 September this year and 29 February next year. It also advises doctors to 'check all dates and actions' so they can 'demonstrate you have taken all adequate and reasonable steps to protect patients in the event of a claim'.
