From waiting lists to weekend impact: How high-volume dermatology clinics transformed access in a London trust

Long waits in dermatology can delay diagnoses, increase patient anxiety, and strain services already under pressure. In late 2023, an NHS Trust in London partnered with 18 Week Support (18WS) to deliver a targeted weekend model designed to restore timely access and reduce backlogs.

The result was a high-throughput approach that combined outpatient clinics with surgical theatres – accelerating patient pathways without compromising on safety or quality.

The vision

The challenge was clear: reduce long waits, including 52-, 65- and 78-week breaches, while preserving core weekday capacity. With backlogs continuing to grow and weekday clinics at capacity, a weekend solution was essential.

The results

• 3,842 patients treated in just seven months

• 2,642 outpatients seen

• 1,200 surgical procedures delivered

• 72 patients seen on average per day

Why it worked

Built to last

What began as a short-term recovery initiative evolved into a scalable model for delivering high-quality elective dermatology care.

With measurable impact on access, performance, and patient experience, the partnership showcases how strategic insourcing can drive long-term transformation – without compromising governance, safety, or outcomes.
