"One stop" clinic for upper gastrointestinal cancer-an alternative to "straight to test" referrals?

Background: Patients suspected to have upper gastrointestinal (UGI) cancer can be referred directly for investigation; however, at times this may result to inappropriate referrals. This study explores the model of a "one-stop" clinic as an alternative to the direct referral system. The current study aims to assess the feasibility and outcomes of a one-stop UGI clinic and evaluate sensitivity and specificity of "on-the-day" diagnoses.

Methods: A retrospective analysis of case notes of patients seen in one-stop clinic, between January 2017 and January 2019, was conducted. All General Practitioner (GP) referrals were screened by a specialist nurse.

Results: After completion of the post-GP referral screening process, 252 patients (median age 68 years, IQR 58.8-77.3 years; M:F ratio 118:134) were allocated to the one-stop clinic. OGD was not required, contra-indicated or declined in 27 cases (10.7%). The records of three patients could not be found. One patient did not attend. Overall, 221 patients underwent testing and received "on-the-day" diagnoses. Sensitivity was 94% (range 87-100%), and specificity was 92% (88-96%). Ninety-six percent of patients received a diagnosis on the day.

Conclusions: The one-stop clinic was feasible and had good specificity and sensitivity. The finding of 10.7% of cases not being suitable for OGD indicates that a patient/specialist consultation is necessary to prevent misuse of endoscopy appointments. The authors recommend widespread adoption of one-stop clinics in UGI surgery.
