General practitioners' knowledge about patients and use of medical records in out of hours calls.

The medical record is an established adjunct to good care and this paper describes the extent to which general practitioners use patients' records in out of hours calls and how their previous knowledge of their patients affects the decision to visit. Seven general practitioners from three group practices in Cambridge and Newmarket each operating a separate out of hours rota recorded details of out of hours telephone calls. Of 368 calls recorded, 293 (80%) resulted in a visit. In 51% of calls the patient was known to the doctor but the doctors were just as likely to visit patients they knew as those unknown to them. In 41% of the calls the doctors were able to recall a degree of clinically relevant information about the patient. In 47 of the calls (13%) recalled information concerning the patient was an influence in the decision whether to visit. The patient's record was collected before the visit in 30% of visits to the elderly compared with 17% for all age groups. The most often quoted reasons for not collecting the medical record were that it was likely to be unhelpful and/or it was geographically inconvenient. Although doctors who collected the record found it useful in 84% of cases, obtaining the record either before or after the visit rarely changed the management of the patient. On the occasions when it did affect management it was of importance both clinically and medico-legally.(ABSTRACT TRUNCATED AT 250 WORDS)
