Episode 355: Reporting lab results – the cause of, and the solution to, the overdiagnosis problem – Part IV

In episode 355, James and Mike finish delving into the issues around lab reporting and measurements. We finally get to some potential solutions (sort of) with how to deal with the variation seen around all lab values/measurements. We focus primarily by describing the variation around the top 20-30 lab tests because there is no way to get away from the inherent biologic variation seen with all these tests. Hopefully, if one appreciates the variation, one can use good clinical skills and judgment when it comes to interpreting lab tests. Or maybe the entire podcast series  just makes your blood pressure up – which as we talk about in the podcast, BP changes are difficult to evaluate.

Episode 354: Reporting lab results – the cause of, and the solution to, the overdiagnosis problem – Part III

In episode 354, James and Mike continue to delve into the issues around lab reporting and measurements. In this part, we talk about the variation seen with blood pressure measurements, glucose and Vitamin D as further examples of what clinicians need to be aware. Having this insight should give you more confidence to interpret lab values, or just frustrate the heck out of you. You decide.

Episode 353: Reporting lab results – the cause of, and the solution to, the overdiagnosis problem – Part II

In episode 353, James and Mike continue to delve into the issues around lab reporting. In this part, we talk about the variation seen with every measurement. We talk about reference change values and what they mean for clinical practice. We use examples of bone density and cholesterol to explain some of the nuances and problems associated with test variance. The bottom line is that cholesterol and BMD measurements, with rare exception, are of no clinical value. Yikes!

Episode 352: Reporting lab results – the cause of, and the solution to, the overdiagnosis problem

In episode 352, James and Mike start to delve into the issues around lab reporting and the numbers that are reported and what the numbers really mean. We talk about the highs and the lows and the variability associated with measurement and realize at the end that, while lab tests may have important variability, the quality of our podcasts never varies – which may or may not be a good thing.

Episode 351: PREMIUM – O2 in COPD and bariatric surgery for diabetes

In episode 351, Mike and James welcome Danielle and Joey to the podcast and they go all PREMIUM on us. The new dynamic duo go over studies from 2 important areas – O2 for COPD and bariatric surgery for diabetes. At the end of the podcast we realize that Mike and James are superfluous when it comes to the podcast quality and usefulness – sad!

Episode 350: Trouble Sleeping: Spend less time in Bed?

In episode 350, Mike and James talk about the evidence around sleep restriction. The evidence is fairly solid and the results typically suggest an impact greater than sleeping pills with sleep restriction improving sleep for one in every two to six patients compared to sleep hygiene alone.  At the end of the podcast, James realises that Mike presented the evidence while being fast asleep – showing that the concept of sleep restriction actually works.

Episode 349: Screening with a complete blood count is evidently of no value

In episode 349, Mike and James talk about the evidence around screening otherwise asymptomatic adults with a complete blood count. While it feels like it should be a good thing to do, the evidence is pretty clear that it doesn’t provide any benefit even though ~ 10% of tests will be abnormal. Basically no one benefits and serious disease is virtually never found.

Episode 348: What is Urgent About Hypertensive Urgency?

In episode 348, Mike and James invite Mike Kolber yet again and he urgently works us through the evidence for treating hypertensive urgency. At the end we realize that asymptomatic patients with BPs >180/110 mmHg can be dealt with addition or initiation of oral agents at presentation with close outpatient follow-up. Even though it is “urgent” we don’t need to panic.
