Introduction Considerable resources have been used to achieve DOH targets for Two-week Colorectal Clinics (TWC) but few studies have monitored the increase in referrals, the decrease in diagnostic yield (DY) of referral criteria and whether this costly strategy has improved outcomes.
Method A prospective study of the numbers referred to the TWC in Portsmouth for each of the referral criteria and the DY for bowel cancer in 2013/14 compared with 2000/1.1
Results The last 12 years has seen a 235% increase (6951to 16362) in referrals to the TWC, compared to a 130% increase (18151to 24042) in routine clinics. 41% of all new patient referrals to surgical clinics are to the TWC, compared to 27% in 2000/1. An extra 194 clinics per year are required to see these patients. DY for cancer in the TWC has fallen from 9.4% (65/695) to 4.1% (20/487). The greatest fall was for patients referred with a change in bowel habit with rectal bleeding.
Conclusion A doubling in outpatient staff has been required to cope with the increase in referrals to the TWC. There has been a decrease in adherence to the TWC referral criteria, particularly change in bowel habit, resulting in a DY of 1.8% (3/170) for patients referred with C+B-. Unless this is improved there is little point in continuing with the TWC.
