Paper of the week 10.01.19: International variation in radiation dose for computed tomography examinations

2019-01-10T12:00:47+00:00

Reference: International variation in radiation dose for computed tomography examinations: prospective cohort study. Rebecca Smith-Bindman et al BMJ 2019;364:k4931 This week’s paper of the week is brought to you by Professor Sir Muir Gray, 3V Executive Director. Bottom line The authors conclusion was that: Variation was chiefly driven by how machines were used, rather than by patient or machine manufacturer or model.       Implications for value improvement  This is an example of what has been called a ‘one tailed curve’ namely a distribution curve where we are clear about what is good and what is not good. In this case lower doses are better than higher doses because there is no evidence that the higher dose improves outcome. [...]

Paper of the week: Temporal trends in use of tests in UK primary care

2018-12-21T10:47:25+00:00

This weeks paper of the week focuses on 'Temporal trends in use of tests in UK primary care, 2000-15: retrospective analysis of 250 million tests'. Listen to the podcast to hear author Jack O'Sullivan talk about this paper with 3V's Dr Tim Wilson Reference: O’Sullivan Jack W, Stevens Sarah, Hobbs F D Richard, Salisbury Chris, Little Paul, Goldacre Benet al. Temporal trends in use of tests in UK primary care, 2000-15: retrospective analysis of 250 million tests BMJ 2018; 363 :k4666 3V's Bottom Line There has been an 8% per annum increase in testing in UK primary care. Some of this increase will represent better monitoring or attempts to make earlier diagnoses. But some may represent overuse of testing, and certainly the impact of the increase is not just in the cost of testing, [...]
