Secondary Prevention of Esophageal Variceal Bleeding Is Often Imperfect: A National, Population-Based Cohort Study of 3592 Patients.

ABSTRACT

BACKGROUND AND AIMS: Secondary prevention of esophageal variceal bleeding is important to improve prognosis, but uptake of guidelines is unknown in a real-world setting. Here, we determined the proportion of patients receiving appropriate nonselective beta-blocker treatment and repeat upper endoscopy after a first episode of esophageal variceal bleeding within a reasonable time frame. METHODS: Population-based registers were used to identify all patients with a first episode of esophageal variceal bleeding in Sweden from 2006 to 2020. Crosslinkage between registers was performed to receive information on the cumulative incidence of patients with a dispensation of nonselective beta-blockers and repeat upper endoscopy within 120 days from baseline. Overall mortality was investigated using Cox regression. RESULTS: In total, 3592 patients were identified, with a median age of 63 (interquartile range, 54-71) years. The cumulative incidence of a dispensation of nonselective beta-blockers and a repeat endoscopy within 120 days was 33%. A total of 77% received either of these treatments. Overall mortality was high, with 65% of patients dying after esophageal variceal bleeding during the full follow-up period (median 1.7 years). We observed an improved overall mortality during the later years of the study period (adjusted hazard ratio for the 2016-2020 period compared with the 2006-2010 period, 0.80; 95% confidence interval, 0.71-0.89). Patients with receipt of nonselective beta-blockers and repeat upper endoscopy had better overall survival compared with those without (adjusted hazard ratio, 0.80; 95% confidence interval, 0.72-0.90). CONCLUSIONS: Secondary prevention of esophageal variceal bleeding has not been widely undertaken, with many patients not receiving guideline-supported interventions within a reasonable time frame. This highlights a need to raise awareness on appropriate prevention strategies to clinicians and patients.
