Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main study parameter / endpoint: accuracy (PPV, NPV, sensitivity, and specificity) of the eNose for detecting confirmed BE with the diagnosis made by transnasal endoscopy and upper endoscopy as the reference standard in primary care. Gold standard: transnasal endoscopy and upper endoscopy. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary study parameters / endpoints: - Patient acceptability of the eNose, the uTNE and if applicable the upper endoscopy (i.e. test experience) (directly after procedure) - Willingness to undergo repeat procedure (directly after procedure) - CWS-8 (at baseline, 7 days and 30 days after procedure and 90 days after the last study procedure (i.e. uTNE or if applicable the upper endoscopy)) - STAI-6 (at baseline, 7 days and 30 days after procedure and 90 days after the last study procedure (i.e. uTNE or if applicable the upper endoscopy)) - IES-15 (7 days and 30 days after procedure and 90 days after the last study procedure (i.e. uTNE or if applicable the upper endoscopy)) - Endoscopic findings, procedure yield, defined as the proportion of patients found to have Barrett*s esophagus or (early stage) esophageal cancer, or another finding - Rate of successful intubation and complete evaluation by uTNE - Safety of the eNose breath test and uTNE (Adverse Events) - Reproducibility of a positive breath test - Number of confirmed diagnoses of Barrett*s esophagus (defined as >1cm of columnar metaplasia combined with the presence of intestinal metaplasia on biopsies) - Rate and quality of successful biopsies taken by uTNE (number, size, and quality of biopsies sufficient for histologic diagnosis) Other study parameters: Demographics: gender, age, civil status, employment status, social status, BMI, waist circumference. General medical history: hypertension, cardiovascular, pulmonary, hepatic, diabetes, GERD symptoms, malignancies, infectious diseases and medication use (including heartburn medication). Alarm symptoms: hematemesis, melena, weight loss, fever. Lifestyle factors: tobacco use, alcohol use, physical activity, diet. Endoscopic and histologic diagnosis: Prague classification (length of BE), presence of esophagitis, hiatal hernia or dysplasia, other conditions. Family history: number of first-grade relatives with BE or EAC. Test char | — |
