Yield of alarm features in predicting significant endoscopic findings among hospitalized patients with dyspepsia.

BACKGROUND

Dyspepsia is a very prevalent upper gastrointestinal tract symptoms complex. Some of these symptoms might arise from serious underlying diseases, so the promotion of evidence-based guidelines could potentially better align evaluation and treatment.

AIM

To determine the value of alarm features as a predictive factor for significant endoscopic findings (SEFs) among hospitalized patients presenting with dyspepsia.

METHODS

We conducted a retrospective case-control study including information about 6208 endoscopic procedures performed for hospitalized patients. Patients were divided into two groups, with and without SEFs, and compared to elucidate the ability of the different alarm features to predict SEFs.

RESULTS

During the study, 605 patients fulfilled the inclusion criteria. When the demographics and clinical characteristics of the two groups were compared, tachycardia ( < 0.05), normocytic anemia, ( < 0.05), leukocytosis ( < 0.05), and hypoalbuminemia ( < 0.05) documented on admission prior to endoscopy were strong predictors of SEFs. Among the alarm features, upper gastrointestinal bleeding, persistent vomiting, odynophagia [odds ratio (OR) = 3.81, < 0.05; OR = 1.75, = 0.03; and OR = 7.81, = 0.07, respectively] were associated with SEFs. Unexplained weight loss was strongly associated with malignancy as an endoscopic finding (OR = 2.05; < 0.05). In addition, long-term use of anti-aggregate medications other than aspirin ( < 0.05) was correlated to SEFs.

CONCLUSION

Novel predictors of SEFs were elucidated in this study. These parameters could be used as an adjunctive in decision making regarding performing upper endoscopy in hospitalized patients with dyspepsia.
