Background and aims
Inpatients developing upper gastrointestinal (GI) haemorrhage are at increased risk of death. This study was performed to elucidate differences in inpatients and outpatients.
Patients/methods
Three hundred and sixty-two patients who needed esophagogastroduodenoscopy for upper GI bleeding were identified from endoscopy charts. Patients’ characteristics, bleeding parameters, clinical presentation, pre-existing medication, and laboratory data were compared between patients who were admitted because of upper GI bleeding and patients who developed bleeding while in hospital for other reasons.
Results/findings
Hospital mortality was 39.0% in inpatients vs. 11.1% in outpatients (p<0.01). Death due to bleeding was observed in 9.5% of inpatients vs. 2.5% of outpatients (p<0.01). Whereas peptic ulcer was the most common source of bleeding in both, variceal bleeding was the most common cause of death because of haemorrhage in both. Recurrent bleeding was associated with mortality in outpatients (p<0.001), but not in inpatients (p=0.11). Rates of bleeding recurrence and need for surgery was similar in both groups. Inpatients suffered more often from renal disease, pulmonary disease, diabetes mellitus, coagulopathy, or immunosuppression, and were treated more frequently with acetylsalicylic acid, glucocorticoids and heparin. The frequency of pre-existing disease was higher in inpatients.
Interpretation/conclusion
Higher mortality after GI bleeding in inpatients than in outpatients is due to a generally higher prevalence of co-morbidity rather than a single or a few risk factors.
