How do emergency departments in England process the results of laboratory investigations?

Aims To determine how emergency departments in England process laboratory investigation results, to identify risk, and to note examples of good practice. Methods A telephone survey was conducted, and data were entered anonymously into Excel spreadsheets. Fisher's exact test was used to test the independence of pairs of variables. Results Data were collected from 167 out of 193 (87%) emergency departments in England. The majority had nurse-requested blood tests. There was a statistical association between nurse-requesting and failure by the clinician seeing the patient to check results. Fourteen (8%) departments did not allow patients to leave until all their results were available. A senior doctor did a second 'safety' check of results in 83 (50%) departments. Many respondents were able to give examples of patients who had been recalled to hospital after a second check. Only a minority of departments had information systems that could identify high-risk patients. Conclusion A second 'safety' check by an experienced consultant, associate specialist or middle grade doctor identifies error. This is time-consuming, but could be supported and simplified by using intelligently designed information systems.
