Background: By high resolution consultation (HRC) we mean an ambulatory process of assistance fulfilled in a single day, by which treatment and diagnosis are established and recorded. Objective: To assess to which extent patients with digestive conditions may benefit from a single consultation system. Material: A descriptive study of 179 first visit events, randomly selected as high-resolution consultations in gastroenterology. We discuss the percentage of patients who benefited from HRC and the complementary tests performed. Results: Most common conditions included dyspepsia (16%), a family history of colon cancer (16%) and gastroesophageal reflux disease (GERD) (16%). Seventy-nine (44%) of all first visits became HRCs and 80 (45%) required a diagnostic test (100% abdominal ultrasound) that was reviewed on the same day. Performing a test on the same day significantly increased the percentage of HRCs (57% vs. 34%, p < 0.002). GERD, dyspepsia, cholelithiasis and chronic liver disease were the subjects most commonly leading to HRC. Conclusions: Gastroenterology consultations may largely benefit from an HRC system with only organizational changes and no additional costs.
