Chat GPT vs Clinician: challenging the diagnostic capabilities of A.I. in dermatology.

BACKGROUND: Chat Generative Pre-trained Transformer (Chat GPT) is an online language-based platform, designed to answer questions in a human-like way, using deep learning technology. OBJECTIVE: To examine the diagnostic capabilities of Chat GPT using real world, anonymised, medical dermatology cases. METHODS: Clinical information from 90 consecutive patients referred to a single dermatology emergency clinic between June to December 2022 were examined. Thirty-six patients were included. Anonymised clinical information was transcribed and input into Chat GPT 4.0 followed by the question "what is the most likely diagnosis?". The suggested diagnosis made by Chat GPT was then compared to the diagnosis made in dermatology. RESULTS: After inputting a clinical history and examination by a dermatologist, Chat GPT made a correct primary diagnosis 56% of the time (20/36). Using the clinical history and cutaneous signs from non-specialists, it was able to make a correct diagnosis 38% of the time (14/36). This was similar to the diagnostic rate of non-specialists 36% (13/36), although much lower than dermatologists (83%, 30/36). There was no differential offered by referring sources 27% of the time (10/36), unlike chat GPT which provided a differential diagnosis 100% of the time. Qualitative analysis showed Chat GPT offered responses with caution, often justifying reasoning. CONCLUSION: This study illustrates that whilst Chat GPT has a diagnostic capability, in its current form it does not significantly improve diagnostic yield in primary or secondary care.

Cutaneous sarcoma: a review and practical approach to management.

Sarcomas arising in the skin are rare but potentially fatal. These tumours originate from mesenchymal cells and can be divided between those that arise in soft tissue and those arising from bone. General guidelines exist for the management of soft-tissue sarcomas; however, there are no specific guidelines for cutaneous sarcomas. Current literature was reviewed for management of seven cutaneous sarcomas including atypical fibroxanthoma, pleomorphic dermal sarcoma, dermal and subcutaneous leiomyosarcoma, dermatofibroma sarcoma protuberans, Kaposi sarcoma, cutaneous angiosarcoma and malignant peripheral nerve sheath tumour. All suspected sarcomas should be discussed in a sarcoma multidisciplinary team meeting. This article is not a clinical guideline but should serve as a practical summary of how these tumours present, how they are recognized histologically, and how best to manage and follow-up patients. The aim is to support clinicians and facilitate the best and most evidence-based standard of care available.

A UK-wide study to describe resource consumption and waste management practices in skin surgery including Mohs micrographic surgery.

BACKGROUND: There is a lack of national guidance specifying how skin surgery, including Mohs micrographic surgery (MMS), should be conducted, leading to a degree of heterogeneity in the set-up of skin surgery services and how skin surgeries are performed. OBJECTIVES: To provide the first UK-wide cross-sectional study reporting real-world data on the set-up and waste management practices of skin surgery, including MMS. METHODS: A UK-wide service evaluation study was conducted between 1 March 2022 and 30 June 2022 using a standardized data collection pro forma. Twelve participating sites from England, Northern Ireland, Scotland and Wales provided data from 115 skin surgery lists involving 495 patients and 547 skin surgery procedures between 1 March 2022 and 30 June 2022. RESULTS: Mean total weight of nonsharps skin surgery waste was 0.52 kg per procedure (0.39 kg clinical waste, 0.05 kg general waste and 0.08 kg recycling waste). Data from a single site using disposable surgical instruments reported a mean of only 0.25 kg of sharps waste per procedure. The recycling rate ranged between 0% and 44% across the cohort with a mean recycling rate of 16%. CONCLUSIONS: We advocate that staff transition to the British Society of Dermatological Surgery 2022 sustainability guidance, which made wide-ranging recommendations to facilitate staff to transition to sustainable practices in skin surgery.

Does music reduce anxiety for patients undergoing dermatological surgery? A systematic review.

BACKGROUND: The incidence of skin cancer is increasing globally, leading to a greater need for dermatologists to perform skin surgery. However, skin surgery can be a potentially stressful experience for patients due to the fear of a possible cancer diagnosis coupled with anxiety related to pain and cosmetic outcomes. AIM: To examine whether there is any evidence to support the hypothesis that listening to music during dermatological surgery under local anaesthesia can help reduce patient anxiety. METHODS: This systematic review considered all original research published until May 2020. Four relevant studies were identified, comprising a total of 381 patients (three randomized control trials and one case-control trial). RESULTS: Two of the four studies showed a significant reduction in perioperative anxiety in patients who had listened to music during surgery. Both of the other studies showed no statistically significant difference between music and no music for patients, although one of these noted reduced anxiety in surgeons. CONCLUSION: There is currently limited evidence to support the use of perioperative music in clinical practice to reduce anxiety in skin surgery. However, given the potential benefits and the likely limited costs of this simple intervention, we believe that further research on this topic is warranted.
