EKU Podcast: Rational testing in primary care
Notas do episódio
Estimates have suggested that 25% of primary care laboratory tests might be ‘unnecessary’, with research demonstrating unwarranted variation and overuse of specific tests including thyroid function tests, liver function tests, prostate- specific antigen tests, and vitamin D tests.
In this podcast Dr Thomas Round talks to Dr Jessica Watson, GP and Consultant Senior Lecturer at the University of Bristol with an interest in evidence based rational testing, about rational testing in primary care. They explore why testing is undertaken in medicine and general practice, when doctors should use blood tests, how to share information about tests with patients, manage patient queries and demand and when to retest.
They discuss the increase in testing demand, the science behind testing and what the evidence shows us regarding over testing. In addition, they review recent research and guidance e.g. accessible results practical toolkits and the PITSTOP project. They also offer top tips for everyday practice and signpost to useful resources.
