Abstract

Objectives: Blood tests for endocrinological derangements are frequently requested in general medical inpatients, in particular those in the older age group. Interrogation of these tests may present opportunities for healthcare savings. Methods: This multicentre retrospective study over a 2.5‐year period examined the frequency with which three common endocrinological investigations [thyroid stimulating hormone (TSH), HbA1c, 25‐hydroxy Vitamin D3] were performed in this population, including the frequency of duplicate tests within a given admission, and the frequency of abnormal test results. The Medicare Benefits Schedule was used to calculate the cost associated with these tests. Results: There were 28,564 individual admissions included in the study. Individuals ≥65 years old were the majority of inpatients in whom the selected tests were performed (80% of tests). TSH was performed in 6730 admissions, HbA1c was performed in 2259 admissions, and vitamin D levels were performed in 5632 admissions. There were 6114 vitamin D tests performed during the study period, of which 2911 (48%) returned outside the normal range. The cost associated with vitamin D level testing was $183,726. Over the study period, 8% of tests for TSH, HbA1c, and Vitamin D were duplicates (where a second test was performed within a single admission), which was associated with a cost of $32,134. Conclusions: Tests for common endocrinological abnormalities are associated with significant healthcare costs. Avenues by which future savings may be pursued include the investigation of strategies to reduce duplicate ordering and examining the rationale and guidelines associated with ordering tests such as vitamin D levels.

26. Should this artificial intelligence algorithm be used in my practice now? A checklist approach.

Abstract

This article discusses the potential use of artificial intelligence (AI) algorithms in medical practice, specifically in the field of ophthalmology. The authors propose a checklist of 10 questions that clinicians can use to determine whether an AI algorithm is ready for clinical use. The checklist includes considerations such as whether the algorithm improves patient outcomes, whether it has been tested against the current standard of care, and whether it may perpetuate healthcare system biases. The authors emphasize the need for ongoing monitoring, maintenance, and cost considerations when implementing AI algorithms in medical practice. [Extracted from the article]
