An Excel spreadsheet template with defined parameters and preset drop-down options was provided to participating practices, with instructions on its use. The template was locked to prevent changes being made to it. The parameters requested were: age at referral, sex, and specific cancer suspected (bladder, brain, breast, cervical, colorectal, endometrial, gallbladder, laryngeal, leukaemia, liver, lung, lymphoma, melanoma, mesothelioma, myeloma, oesophageal, oropharyngeal, ovarian, pancreatic, prostate, renal, sarcoma, small intestine, stomach, testicular, thyroid, vulval, other
AimTo examine primary care referral patterns, compliance with referral guidance, and eventual outcome for patients.
Design and settingProspective audit within general practice in Scotland.
MethodGPs in Scotland reviewed all urgent suspected cancer referrals over a 6-month period. They noted the final diagnosis and assessed whether the referral was in accordance with agreed referral guidelines.
ResultsA total of 18 775 urgent suspected cancer referrals were analysed from 516 GP practices. The referral rate ranged from 3.7 to 24.0 per 1000 per annum; 30.8% of referrals were for patients aged under 50 years, yet this age group accounts for only 11.1% of all diagnosed cancers; 10.3% of all urgent cancer referrals were for suspected melanoma, despite this cancer accounting for only 4.1% of new cancers. The proportion of patients subsequently diagnosed with cancer was greatest for leukaemia (61.7%), prostate (52.6%), and lung cancer referrals (39.7%), and lowest for melanoma (11.8%), oesophago-gastric (11.2%), brain (10.6%), and laryngeal cancer referrals (7.8%). Compliance with referral guidelines was 90.9%. A large proportion of referrals considered to be outside the guidelines still had a cancer diagnosed (urological 15.9%, lung 8.8%, colorectal 8.4%, and breast 6.4%).
ConclusionThere is wide variation in GP referral rates for suspected cancer with a greater than expected proportion of referrals for younger people. Many referrals considered to be outside the national guidelines were diagnosed with cancer, suggesting factors other than those in referral guidelines alert GPs to the possibility of cancer.
