Researchers presented findings from a real-world deployment of an autonomous AI medical device (AIaMD) in urgent suspected skin cancer pathways at two U.K. hospitals. The study, involving 8,391 patients, demonstrated that the AI system could autonomously discharge benign cases, thereby reducing the burden on specialist dermatologists and increasing overall clinical capacity.
A real-world study presented at the European Academy of Dermatology and Venereology (EADV) Congress 2026 evaluated the impact of an autonomous AI medical device on urgent suspected skin cancer referrals in two U.K. hospitals. The prospective study included 8,391 patients, representing 94% of urgent referrals across the sites over a 16-month period. The AI system, which is CE-marked as a Class III medical device, used clinical and dermoscopic smartphone images to classify skin lesions.
The autonomous pathway allowed the AI to independently discharge patients with benign lesions without requiring specialist review. In the study, the AI autonomously discharged 31% of patients at one hospital and 25% at the other. Teledermatologists subsequently discharged an additional 24% and 25% of patients, respectively. This process reduced the proportion of patients requiring routine follow-up from 27% to 12% compared with standard teledermatology, and lowered biopsy rates from 43% to 27% compared with conventional face-to-face care.
The study estimated that the autonomous pathway saved 2,851 hours of clinician time, representing a 62% gain in clinical capacity. Based on standard 20-minute consultations, this time savings was equivalent to more than 8,500 additional face-to-face appointments. Lead author Dr. Lucy Thomas noted that the primary value of the technology lies in unlocking specialist capacity, allowing dermatologists to focus on patients with skin cancer or severe inflammatory skin disease who require timely intervention.
為什麼這很重要
This study provides concrete evidence that autonomous AI can address critical workforce shortages in healthcare. By accurately identifying benign lesions, the system allows scarce specialist time to be redirected toward high-risk patients, potentially improving access to care for skin cancer and severe inflammatory conditions without replacing human clinicians.
Urgent suspected skin cancer referrals in England have nearly tripled since 2009, yet only about 6% result in a cancer diagnosis. Simultaneously, approximately one in four dermatologist roles in the U.K. remains unfilled. This study demonstrates a practical application of autonomous AI to mitigate this imbalance by safely managing low-risk cases, thereby addressing a significant bottleneck in healthcare delivery.
The findings suggest that autonomous AI can serve as a scalable solution for workforce shortages in specialized medical fields. By automating the triage of benign lesions, the system enables a more sustainable model of care where specialist expertise is allocated to high-acuity patients. This approach does not replace dermatologists but augments their capacity, potentially improving prognosis for cancer patients and quality of life for those with chronic skin conditions.
The study highlights the importance of ongoing safety monitoring in autonomous AI deployments. While the system showed high sensitivity for invasive melanoma and common skin cancers, it did result in six false-negative discharges, which were identified through post-market surveillance. This underscores the need for robust oversight mechanisms to ensure patient safety as autonomous AI systems become more integrated into clinical workflows.

Regulatory adoption of autonomous AI medical devices in other specialties, replication of these safety and efficacy results in larger or different healthcare settings, and the long-term impact on dermatology service sustainability and patient outcomes.
Regulatory bodies and healthcare systems may look to replicate this model in other specialties facing similar workforce pressures, such as radiology or pathology. The success of this deployment could influence guidelines for the use of autonomous AI in diagnostic pathways.
Further research will likely focus on validating these results in larger, more diverse populations and different healthcare settings to ensure generalizability. Long-term studies will be essential to assess the sustained impact on patient outcomes and service sustainability.
The integration of autonomous AI into clinical practice will require continued development of safety monitoring frameworks and post-market surveillance protocols to detect and address any performance drift or adverse events promptly.
