2-Week wait referrals in suspected skin cancer: does an instructional module for general practitioners improve diagnostic accuracy?
The two-week wait (2WW) scheme in the United Kingdom for suspected skin cancer has been criticised for having low pick up rates, with a high proportion of clinically benign lesions being referred as suspicious. We studied the referral patterns of skin cancer to our hospital under the 2WW initiative, and aimed to quantify the effect of a targeted continuing medical education (CME) module on improving diagnostic accuracy. All referrals to our hospital (dermatology and plastic surgery) under the 2WW rule were audited between July and September 2006. A targeted CME module was sent to GPs describing and illustrating common lesions. After 11 months, all 2WW referrals were prospectively studied between August and October 2007. The main outcome measure was the percentage of correctly referred squamous cell carcinomas (SCCs) and melanomas. 237 referrals were made between July and August 2006, and 223 referrals between August and October 2007. The proportion of appropriately referred skin cancers (SCCs and melanomas) was 23.2% before CME, and 20.6% after CME. There were no differences in pick up rates before and after the CME amongst suspected SCCs (21.1% vs. 29.7%) or melanomas (24.6% vs. 15.1% respectively). Referrals to Plastic Surgery were more likely to be confirmed histologically as melanomas or SCCs (23.6% and 33.7% respectively) than those made to Dermatology (17.5% and 15.3% respectively). The proportion of correctly suspected skin malignancies under the 2WW initiative remains low despite education. A targeted CME module sent to GPs fails to improve pick up rates. There is a need for continuing dermatology training amongst referring physicians.
