"Test, score and scope": a selection strategy for safe reduction of upper gastrointestinal endoscopies in young dyspeptic patients referred from primary care.

OBJECTIVE: To test the ability of pre-endoscopic clinical evaluation to predict clinically relevant findings of upper gastrointestinal endoscopy.
MATERIAL AND METHODS: Patients (341) who had been referred to upper gastrointestinal endoscopy for further evaluation of dyspeptic symptoms were included in this prospective, single-blinded study. Prior to endoscopy, the patients underwent a standardized clinical evaluation consisting of 1) a symptom questionnaire, 2) serological testing for Helicobacter pylori antibody and 3) determination of blood hemoglobin. Based upon this evaluation, patients were assigned to one of three defined risk groups. Group A comprised patients with known risk factors for diseases that would require further therapeutic or diagnostic management. Patients in groups B and C had no such risk factors. Patients in group C had heartburn or regurgitation as a predominant symptom, whereas patients in group B did not. The prevalence of clinically relevant findings upon upper endoscopy was then compared for these three groups.
RESULTS: The prevalence of clinically relevant endoscopic findings in risk groups A, B and C were 20.1, 2.4 and 1.6%, respectively (p<0.01 for both A versus B and A versus C). Furthermore, 89% of those with clinically relevant endoscopic findings belonged to group A, which comprised a total of 45% of the patients studied. In groups B and C, the prevalence of disease was similar to the area-specific prevalence in the general population without dyspeptic symptoms.
CONCLUSIONS: By using a simple standardized questionnaire, H. pylori serology and a hemoglobin reading in the evaluation of dyspeptic patients under 45 years of age, the need for endoscopy can be reduced by 55%.
