["Our current practice is that initial (day 1) positive blood culture results are communicated to clinical teams; the task of recording those results in the notes is left to the clinical team. Microbiological information may be of crucial importance to an on-call doctor asked to review an unwell patient. We therefore sought to establish the extent to which day 1 positive blood culture information is available in patients' notes and its accuracy.", 'There were 51 positive blood cultures over a 14-day period. Patient notes of 39 of these were available for examination for evidence of the day 1 culture report, the accuracy of that report and evidence of clinical interpretation.', 'The proportion of notes with a record was disappointingly low (54%), although the record was almost always accurate. Results reported at the weekend were as likely to be recorded in the notes as those given during the week.'] Does documentation of positive blood culture result in a London teaching hospital?
