West Suffolk NHS Foundation Trust deploy AI to reduce delays in skin cancer detection and treatment

AI is as good at detecting skin cancer as dermatologists, and since introducing AI into their urgent suspected skin cancer pathway in 2021, WSFT have increased the proportion of patients seen within two weeks from 20% to 95%.


Our impact

5,335

patients seen

4.9 day

average waiting time reduction for first appointment following referral

65%

patients avoided a 2WW F2F dermatology appointment

ASPH needed Skin Analytics‘ help to set up an AI driven routine skin lesion pathway to address their backlog of 396 patients and pick up any premalignant or malignant lesions whilst discharging those lesions that had resolved.

ASPH and Skin Analytics initially partnered together in July 2022. Using Skin Analytics’ AI as a medical device, DERM, ASPH have seen more than 2,400 patients on their Urgent Suspected Cancer (USSC) pathway, of which, 21% have been discharged by Skin Analytics, 14% were redirected to an onward speciality and 14% were downgraded to a routine appointment.

With these benefits, nearly 50% of ASPH’s patients experienced a quicker next step in the post-referral pathway; so ASPH were confident in Skin Analytics’ ability to optimise their routine skin lesion pathway too.

The challenge

Over the last 6 years, there has been an almost 30% increase in 2-week wait dermatology referrals nationally. This rise combined with the impact of COVID-19 has resulted in a considerable backlog in skin cancer pathways [1]. It is expected that cancer referrals will continue to rise [2], particularly in East Anglia where there is a relatively high incidence of skin cancer cases due to its large agricultural workforce and ageing population. Historically, WSFT have looked at solutions including upskilling GPs and teledermatology for RTT, but referrals have remained high due to sub-par image quality and low adoption.

The solution

In collaboration with the local ICS, WSFT and Skin Analytics deployed an AI based service to address the backlog and help to reduce delays in skin cancer detection and treatment, without the need of additional face to face clinics. Within the WSFT pathway, the AI, Deep Ensemble for the Recognition of Malignancy (DERM) provides an immediate classification, re-directing low-risk lesions to be reviewed by a Skin Analytics dermatologist. The dermatologist confirms if the lesion is safe to be discharged while high-risk lesions are available immediately to be reviewed by the WSFT dermatologists virtually. Triaging patient care in this way provides effective management in a timely manner and ensures patients are seen in the appropriate clinic whether that be Dermatology, Plastic Surgery or Oculoplastic Surgery.
