Introduction: Early endoscopic intervention (within 6 hours of admission) in patients with gastrointestinal bleeding (GIB) increases overall mortality but does not improve the mortality, length of stay (LOS), or transfusion requirement in lower GIB, while reducing the LOS in upper GIB. We aimed to study the prognosis of patients undergoing endoscopic intervention in < 1 day compared to ≥ 1 day.

Methods: This is a single-center retrospective cohort analysis of patients admitted to Intermediate unit and ICU with GIB as their primary diagnosis (03/2015 – 03/2021). Medical records of patients above 18 years of age were reviewed for baseline characteristics and lab values. Charlson comorbidity index (CCI), Glasgow Blatchford Score (GBS), AIMS 65, ABC, quick Sequential Organ Failure Assessment (qSOFA) scores on admission were calculated. Patients were compared according to time to scope i.e., < 1 day vs. ≥ 1 day. Outcome variables assessed included hospital LOS, 30-day mortality, and 90-day readmission rate. Pearson Chi-square and Mann Whitney U were applied to compare groups.

Results: Out of 212 patients admitted with GIB, 196 (92.5%) underwent endoscopic intervention in ≥ 1 day and 16 (7.5%) within 1 day. Baseline characteristics are illustrated in Figure 1. Patients scoped ≥ 1 day had higher PRBCs transfused (median 3 vs. 2; p< 0.01) and less frequently received antibiotics (15.3% vs. 37.5%, p< 0.01). None of the scores (GBS, AIM-65, qSOFA, CCI, and ABC) were significantly different between two groups (p-value >0.05). Median (interquartile range (IQR)) of the scores according to time to scope i.e., < 1 day vs. ≥ 1 day is as follows: 14.5 (8.3,15.8) vs. 12.0 (9.0, 14.0); AIM-65: 1.0(0.0, 1.0) vs. 1.0(1.0,2.0); qSOFA: 0.5 (0.0,1.0) vs. 0.0(0.0,1.0); CCI: 4.5(1.5,6.8) vs. 5.0(3.0,6.0); ABC: 0.0(0.0,1.0) vs. 0.0(0.0,0.0). There was no significant difference in hospital LOS and 30-day mortality. However, 90-day readmission rate were higher in patients who underwent endoscopic intervention < 1 day (p=0.04).

Discussion: Comparable risk stratification scores indirectly indicate equivalent severity of GIB between the two groups on presentation. According to our study, early endoscopic intervention does not significantly impact the LOS and 30-day mortality, but increases 90-day readmission rates. Further studies, primarily a prospective analysis, should be pursued to determine whether early endoscopic intervention should be avoided in certain scenarios.
