The implementation of the two-week wait initiative for cancer referrals in the NHS has had a major impact on outpatient services. A low clinical detection rate among GPs for neurological cancer has resulted in a large number of urgent referrals with a low yield of positive diagnoses. We have devised a strategy for minimizing the impact on outpatient clinics: patients are scanned prior to clinical review and those with normal scans are referred back to the GP without a clinic appointment. Out of 69 referrals of suspected CNS cancer made in 2003, 61 were scanned and six resulted in a positive diagnosis. The equivalent of 10 clinics was saved, and an increased speed of diagnosis and treatment was achieved with no compromise in patient care. Our study illustrates the consequences of the 2-week wait initiative on the neurosurgical service, and proposes an effective and safe solution.
