Clinical and demographic predictors of Barrett's esophagus among patients with gastroesophageal reflux disease: a multivariable analysis in veterans.

Background The subgroup of patients with gastroesophageal reflux disease (GERD) that should undergo endoscopy to rule out Barretts esophagus (BE) has not been well defined. Goals To examine demographic and clinical variables predictive of BE before endoscopy. Study A validated GERD questionnaire was administered to 107 patients with biopsy-proven BE and to 104 patients with GERD but no BE shown by endoscopy. Frequent symptoms were defined as symptoms that occurred at least once or more each week. Severity of symptoms was rated on a scale from 1 to 4 (mild to very severe). Univariate analysis and multivariable logistic regression were performed to determine whether demographic characteristics and the duration, severity, and frequency of GERD symptoms were associated with the identification of BE. Results Eighty-five percent of the GERD patients and 82% of the BE patients completed the questionnaire. There was no difference between the groups in terms of race, gender, or proton pump inhibitor use. The BE patients were older (median age, 64 vs. 57 years, p = 0.04). In multivariable logistic regression, an age of more than 40 years (p = 0.008), the presence of heartburn or acid regurgitation (p = 0.03), and heartburn more than once a week (p = 0.007) were all independent predictors of the presence of BE. Interestingly, patients with BE were less likely to report severe GERD symptoms (p = 0.0008) and nocturnal symptoms (p = 0.03). Duration of symptoms, race, alcohol, and smoking history were not associated with BE. Conclusions Upper endoscopy should be performed in GERD patients more than 40 years of age who report heartburn once or more per week. The severity of symptoms and the presence of nocturnal symptoms are not reliable indicators of the presence of BE.

Health-related quality of life and severity of symptoms in patients with Barrett's esophagus and gastroesophageal reflux disease patients without Barrett's esophagus.

OBJECTIVES:The aims of this study were: 1) to compare the health-related quality of life (HRQL) of patients with Barretts esophagus (BE) to that of patients with GERD who did not have BE;2) to compare HRQL of gastroesophageal reflux disease (GERD) patients to that of normative data for the US general population; and 3) to examine the impact of GERD symptom frequency and severity on HRQL.METHODS:The SF-36 and a validated GERD questionnaire were administered to 107 patients with biopsy-proven BE and to 104 patients with GERD but no BE by endoscopy. Frequent symptoms were defined as symptoms that occurred at least once weekly. Severity of symptoms was rated on a scale from 1 to 4 (mild to very severe).RESULTS:In all, 85% of the GERD patients and 82% of BE patients completed the questionnaires. There was no difference in the scores of the eight subscales of the SF-36 between BE patients and those with GERD but without BE (p > 0.05). However, both groups scored below average on all subscales of the SF-36 compared to published US norms for an age- and gender-matched group. Using multivariable linear regression, the social functioning subscale of the SF-36 correlated with the presence of heartburn or acid regurgitation, severity of acid regurgitation, frequency of heartburn, frequency of acid regurgitation, and number of comorbidities. Similarly, the physical functioning subscale correlated with age, frequency of heartburn, and number of comorbidities. The bodily pain subscale correlated with the frequency of heartburn and number of comorbidities. The bodily pain subscale correlated with the frequency of heartburn and the severity of dysphagia, whereas the role emotional subscale correlated with the frequency of heartburn and the presence of dysphagia.CONCLUSIONS:Although there were no differences in HRQL between BE and GERD patients, both groups scored below average on the subscales of the SF-36 compared to normal controls. GERD symptom frequency and severity were associated with bodily pain and with impaired social, emotional, and physical functioning, suggesting a profound impact on daily living.

Factors associated with acceptance and full publication of GI endoscopic research originally published in abstract form

BACKGROUND Many abstracts submitted to annual scientific meetings never come to full publication in peer-reviewed journals. The objective of this study was to determine factors associated with the fate of endoscopic research abstracts submitted to the annual scientific meeting of the American Society for Gastrointestinal Endoscopy (ASGE). METHODS All abstracts (n = 461) submitted to the annual meeting of the ASGE in May of 1994 were retrospectively reviewed. The following databases were searched for evidence of publication of abstracts in full-manuscript form: Medline, HealthSTAR, Current Contents, CINHAL, and Cancerlit. All abstracts were reviewed between May 4, 1998 and June 30, 1998. Univariate and multivariate analysis were performed to determine the association between abstract characteristics and acceptance for presentation at the meeting and for publication. RESULTS Fifty-five percent (247/451) of submitted abstracts were accepted for presentation. In univariate analysis, pediatric studies, prospective studies, randomized studies, and studies from university-affiliated medical centers (UAMC), were more likely to be accepted for presentation (p < 0.05). In multivariate analysis, the variables: pediatric studies (p = 0.01), prospective studies (p = 0.005), randomized studies (p = 0.06), and studies from UAMC (p = 0.01) predicted acceptance of abstracts for presentation at the meeting. The overall publication rate was 25.1%. The publication rates 1, 2, 3, and 4 years after the meeting were 6.7%, 16.2%, 22.8%, and 25.1%, respectively. Multivariate Cox proportional hazards analysis showed that accepted abstracts (p = 0.0003) studies reporting positive results (p = 0.0015), and studies from outside the United States (p = 0.036) were more likely to be published in manuscript form. CONCLUSIONS The overall publication rate of abstracts reporting endoscopic research is 25%, lower than that in any published report from other medical societies. Abstracts from the United States were less likely to be published in full-manuscript form. Although there was no positive outcome bias for acceptance of abstracts for presentation at the meeting, there was bias toward publication of statistically significant results. Further investigations are warranted to determine the variation in the publication of research results according to country of origin and to determine factors that hinder publication of GI endoscopic research in manuscript form.

A cost analysis of outpatient care for patients with Barrett's esophagus in a managed care setting.

OBJECTIVES:Although Barretts esophagus (BE) may be associated with severe gastroesophageal reflux disease (GERD), there are currently no studies that evaluate resource utilization in Barretts patients. The aims of this study were 1) to determine the cost and number of endoscopies and clinic visits to the GI clinic for GERD or its complications in patients with BE; 2) to determine the pattern and cost of medication use in patients with BE; and 3) to compare medication use by patients with BE to that of patients with insulin-requiring diabetes mellitus (DM).METHODS:Using the cost distribution report data and the pharmacy acquisition costs from the Durham VAMC, we calculated the monthly cost of endoscopies, clinic visits related to GERD, and medication use in 53 patients with BE between 1/1/94 and 1/1/97. We also calculated the average cost of medication use for 55 patients with insulin-requiring DM.RESULTS:All patients with BE were male. Their median age was 64.0 yr (IQR 57–68). Of them, 92% were white; 23% had low-grade dysplasia (LGD). Patients with LGD were more likely to have more than three endoscopies in 3 yr than were those with no LGD (OR 6.3, 95% CI 1.11–35.67). There was no difference in clinic visits in the patients with and without dysplasia (OR 0.335, 95% CI 0.093–1.206). A total of 139 endoscopies and 172 clinic visits were observed. Outpatient care for patients with BE costs approximately

Medication cost per month in patients with BE was approximately
