Clinicians have been paying more attention to the problem of overdiagnosis as part of the more general problem of “overmedicalization” of society in general. This also includes overtreatment, diagnostic creep, and disease mongering.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;In this issue of &lt;i&gt;JACEP Open&lt;/i&gt;, Meltzer et al demonstrated that a point-of-care multiplex polymerase chain reaction (PCR) analyzer identifying the microbiological cause of an infectious disease at an urgent care center (UCC) led to increased patient satisfaction.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; Patients presenting to an UCC with respiratory symptoms were randomized to point-of-care multiplex PCR testing identifying viral and bacterial pathogens or a control group that got no testing. They found patients were more cognizant of the need to quarantine and take time off work when they knew the test results. There was no significant effect on antibiotic prescription, although the study was only powered for patients’ satisfaction.&lt;/p&gt;&lt;p&gt;Superficially, this seems reasonable for UCCs, and some may argue that this technology could be useful in the Emergency Department. However, this begs the question of whether the wider use of these diagnostic tools would increase the potential for overdiagnosis.&lt;/p&gt;&lt;p&gt;The definition of overdiagnosis was articulated in a 2018 editorial:&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; “identification of abnormalities that were never going to cause harm, abnormalities that do not progress, that progress too slowly to cause symptoms or harm during a person's remaining lifetime, or that resolve spontaneously.” They focused primarily on the overdiagnosis of cancers, but the concept is also applicable here. Overdiagnosis and over-testing are a complex problem, with many implications. The risk of overdiagnosis increases with the number of tests ordered that identify a disease not destined to meaningfully harm the patient, making the risks of testing outweigh the benefits. While difficult to determine at the individual level, this should be studied in population samples where the chance of an overdiagnosis in a particular situation can be estimated.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;It is understood that overdiagnosis has many harms including the cost of the tests, the need for follow-up testing, treatment for diseases that will not affect health or longevity, and giving patients either a false sense of security or causing unnecessary anxiety.  Patients may not understand why testing should be avoided and health care providers must spend more time counselling patients to avoid unnecessary testing.&lt;/p&gt;&lt;p&gt;Overused medical testing also effects patients’ life by involving them in more frequent medical encounters and potentially serious effects of unnecessary treatment.  Another harmful impact is that patients","PeriodicalId":73967,"journal":{"name":"Journal of the American College of Emergency Physicians open","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/emp2.13307","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142448989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He was employed at a livestock slaughterhouse and did not wear gloves when handling animals. The most common animals he was in contact with were sheep and goats. The rash was only in one location, between his third and fourth digit on his left hand (Figures 1 and 2) and worsened over the previous 4 days. The blister is approximately 1 cm × 1 cm × 1 cm and tender to touch. He denied any fevers, chills, or additional rashes. Due to the uniqueness of the patient's profession, dermatology was consulted and a shave biopsy was performed.</p><p>The patient was ultimately diagnosed with Orf virus based on clinical presentation alone. Tissue biopsy showed epidermal hyperplasia with vacuolated cytoplasm and eosinophilic inclusion bodies in upper epidermal keratinocytes, ulceration, and mixed inflammatory infiltrate, which aligned with the clinical diagnosis of Orf. Orf is caused by the <i>Parapoxvirus</i> and is often self-limiting, lasting around 4–6 weeks. It is found in people who have direct contact with animals, most commonly farms. Treatment is mainly supportive, cleaning the wound with soap and water, and keeping the wound dry and covered with a bandage. It is important to keep zoonotic diseases on the differential of rash.</p>","PeriodicalId":73967,"journal":{"name":"Journal of the American College of Emergency Physicians open","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/emp2.13286","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142447603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
