Background:
Early endoscopy has been shown to improve outcomes and optimize cost-effectiveness in nonvariceal upper-GI bleeding (NVUGIB). However, there is little information regarding clinical and process determinants that affect the time from onset of bleeding to performance of the endoscopy.
Objective:
The aim of this study was to identify factors that predict time to endoscopy in patients with new onset NVUGIB.
Design:
Linear regression models were constructed with time between triage (outpatients) or onset of bleeding (inpatients) and the performance of endoscopy.
Setting:
The RUGBE is a nationwide, multicenter database collected for the purpose of obtaining descriptive data on patients with NVUGIB.
Patients:
The study population consisted of 1500 patients (89.6%) who underwent gastroscopy within 48 hours.
Results:
Median time to endoscopy was 12 hours (95% CI 11.0, 13.0). Endoscopy after working hours (regression coefficient [beta] -3.52; 95% CI -5.47, -1.58), availability of an endoscopy nurse on-call for the procedure (beta -2.48; 95% CI -3.83, -1.14), and admission to a hospital unit were associated with a shorter interval to endoscopy. In contrast, the presence of chest pain (beta 3.65; 95% CI 1.64, 5.67) or dyspnea (beta 2.79; 95% CI 1.10, 4.48), absence of gross blood on rectal examination (beta 2.20; 95% CI 0.69, 3.71), and inpatient status at onset of bleeding (beta 14.6; 95% CI 8.70, 20.4) were independent predictors of a delayed endoscopy. Subgroup analysis showed that actual time intervals as well as independent predictors of time until endoscopy differed between inpatients and outpatients.
Limitations:
Retrospective analysis.
Conclusions:
The timing of endoscopy in patients with NVUGIB is dependent on both clinical and process parameters, which differ between inpatient and outpatient settings. They bear implications with regards to shaping practice and deciding on resource allocation in order to facilitate an early endoscopy, which is currently recommended for improved patient outcomes.
