Baseline tests or screening: what tests do family physicians order routinely on their healthy patients?

Abstract

The purpose of this study was to survey the attitudes of family doctors to the performance of baseline tests and to determine which doctors perform these tests. Family physicians in a continuing medical education programme in Tel Aviv, Israel. An anonymous questionnaire was distributed focusing on performance of tests by doctors in healthy patients and not as part of a screening programme. Questionnaires were returned by 147 of 165 physicians surveyed (89% response rate). Baseline tests were performed by 98% of respondents: not routinely by 54%, 7% at the patient's request, and 2% did not perform tests. The decision to perform baseline tests was influenced by the presence of other risk factors of disease (86%), patient age (61%), family history (59%), patient request for tests (24%), and patient sex (20%). The tests performed were blood counts, glucose, renal function tests, urinalysis, liver function tests, and electrocardiograms. Baseline tests were useful in case finding of new illnesses for 49% of physicians and 40% said the tests had proved useful during a subsequent illness. The remainder of the physicians found no use for baseline tests. Physicians from the former Soviet Union were more likely to favour baseline tests. Almost all of the physicians in this study reported that they perform baseline tests on most of their patients. Evidence based guidelines for these tests and education of physicians are needed.
