Dangers in the Beauty Industry
PodcastDX
This week we discuss dangers in the beauty industry. From a client's perspective, the issues might not be as severe, but the clinicians who must deal with chemicals day in and day out are at a greater risk. The average woman uses 12 different beauty products every day — cleansers, conditioners, hair dyes, fragrances, skin care products, scented lotions, nail polish, and makeup, to name a few. Take a quick glance at the labels, and you'll see a cocktail of chemical components. You might assume that all these ingredients have been tested to ensure that they're safe for long-term...

Elderly Fade
PodcastDX
This week's episode has the cohosts talking about social isolation and earlier death among the elderly population. Studies have shown that loneliness is associated with a higher risk of mortality in older adults. For example, one study found that individuals experiencing loneliness at one or more points in time had a higher hazard for mortality compared to those who never experienced loneliness. Loneliness can trigger physiological stress responses, potentially leading to chronic inflammation and reduced immunity. These factors can contribute to the development of...

Tularemia or Rabbit Fever
PodcastDX
Tularemia is a highly infectious disease you get from the bacterium F. tularensis. You can get it from bug bites, infected animals, contaminated water or food, and particles of bacteria in the air. Tularemia can affect your skin, eyes, throat, lungs and intestines. Tularemia should be treated as soon as possible with antibiotics. We will not have a guest for this week, but would love to invite anyone who has been diagnosed with Tularemia to be a guest on a future show. Tularemia causes your lymph nodes to painfully swell and other symptoms in your lungs, eyes, throat and intestines,...

Blastomycosis
PodcastDX
Our guest for this week is Sara Olson. Sara (her TikTok name is ) is from the Wolf River area of Wisconsin which just happens to hold the highest concentration of the fungus that causes Blastomycosis. When Sara got Blastomycosis in January 2024, she thought it was 'just the flu'. With a chest xray, she was diagnosed with pneumonia. Several rounds of antibiotics didn't help so she did a CT scan where they found an embolism. Still not knowing anything else, they continued treating her for bacterial pneumonia. They did a swab of her sputum in which her health...

This week we will discuss the topic of Diagnostic Radiology. The error rate of radiology is 4% world wide which comes out to be 40 million interpretive errors a year. Errors in diagnostic radiology occur for a variety of reasons related to human error, technical factors and system faults. It is important to recognize that various cognitive biases contribute to these errors.
Cognitive biases have a complex and significant impact on the perception of examinations within diagnostic radiology, with the clear and present danger of diagnostic errors. The following are some of the more common cognitive biases that can affect day-to-day decision making
Alliterative bias
Alliterative bias (sometimes called satisfaction of report) is the tendency for your diagnostic impression to be unduly influenced by the prior interpretation made by another radiologist or clinician. It is a type of confirmation bias and it can result in the same incorrect impression being propagated from one radiologist to the next. Formulating your own interpretation before reviewing any prior imaging reports may help reduce alliterative bias.
Anchoring bias
Anchoring bias is the tendency for your initial impression to unduly influence your evaluation of subsequently collected information. Careful assessment of all imaging findings prior to formulating a diagnosis and consideration of alternate diagnoses may help minimize anchoring bias.
Automation bias
Automation bias is the tendency for reporters using computer-aided decision support to over rely on the software for the diagnosis, and to ignore their own opinions 2. Making your own assessment prior to reviewing the computer-aided findings, and knowing the limitations of the automated software, can help reduce this bias.
Availability bias
Availability bias refers to the tendency for your diagnostic judgements to be unduly influenced by information or experiences that are readily recalled in your mind. Use of information sources beyond your own personal experience, such as publications or an opinion from colleagues, may help to minimize availability bias.
Bandwagon effect
The bandwagon effect (sometimes termed diagnosis momentum) refers to the tendency for you to do or think as others do, simply because that's what others are doing. Applying your own judgment and not dismissing your own opinion can help avoid this bias.
Confirmation bias
Having a predetermined diagnosis in mind, then looking for evidence that supports this predetermined idea. Alliterative errors 3, sometimes referred to as satisfaction of report errors, are caused by the tendency to overvalue previous reports, and can be conceptualised as a type of confirmation bias.
Framing bias
Framing bias refers to the tendency to be unduly influenced by how a clinical question is asked or how the problem is presented. For example, a request form that presents a succinct history that perfectly matches a particular pathology, may influence your interpretation of the imaging. Reviewing the images prior to reading the clinical indication can help avoid any influence. Obtaining more detailed clinical information via the electronic medical record may help provide you with a more balanced assessment of the clinical situation.
Hindsight bias
Hindsight bias is the tendency to overestimate the prior predictability of an event (eg. a diagnosis) after the event is known. In other words, the difficulty of making the correct diagnostic decision initially is retrospectively de-emphasized, after the diagnosis has been proven. It is also informally termed as the “I knew it all along” or "retrospectoscope" bias 5. It is important to be conscious of this bias so that you are not overly critical of yourself or others when quite reasonable errors are made.
Outcome bias
A tendency to favor a less severe diagnosis based on empathy for a patient.
Representativeness bias
Making a judgment on an aspect of an image that is based on one's own perception of what that represents. Representativeness bias as the description suggest can also be heuristic in nature.
Search satisfaction
Search satisfaction is the tendency to prematurely stop searching after early findings satisfy the reader that the diagnosis or symptoms can be explained. Satisfaction of search (SOS) errors have been reported to account for 22% of diagnostic errors 4. A systematic approach to image interpretation and review of check areas and not-to-miss diagnoses can help to reduce this bias.
Zebra retreat bias
A reader will not make a rare diagnosis, which is otherwise supported by the available evidence due to a lack of confidence.
