The better use to improve laboratory requesting patterns among primary care physicians: a systematic review in Makah al-Mokaramahat Saudi Arabia 2024

Abstract

Background: Laboratory tests are important tools in primary care, but their use is sometimes inappropriate. Laboratory tests are essential for screening, diagnosis and monitoring of diseases and are extensively used both in primary care.There is ample evidence that many laboratory investigations requested are not necessary.  Repeat laboratory investigations are a common cause of unnecessary requests. It is generally recognized that the number of laboratory tests are increasing far more than the number of patients. The increased uses of tests probably have benefited some patients through earlier diagnosis and treatment, however, their contribution to the quality of care also is debatable. This is especially the case when the usage is not based on clinical need and scientific evidence, but rather on habits, defensive medicine or similar causes.
