RESUMO
INTRODUCTION: Patients with disorders of gut-brain interaction (DGBIs) are high users of health care. Past studies exploring predictors of utilization have lacked patient-level clinical data. The aim of the current study is to identify demographic, clinical, and psychological predictors of health care utilization in patients with irritable bowel syndrome (IBS), functional constipation (FC), and functional diarrhea (FDr). METHODS: Consecutive new patients diagnosed with IBS, FC, and FDr (using Rome IV criteria) completed questionnaires assessing health care utilization as well as clinical and psychological symptoms. Health care utilization was assessed using a 13-item measure inquiring about the previous 6 months. Patient-Reported Outcome Measures Information System (PROMIS) was used to assess severity of abdominal pain, constipation, diarrhea, anxiety, depression, and sleep disturbance. RESULTS: Of the 507 patients diagnosed with IBS, FC, or FDr, 434 completed the health care utilization questionnaire (mean age of 44 years, 79.5% female, and 73.5% IBS). In the final multivariable models, more severe abdominal pain and higher depression scores were significantly associated with increased utilization of (i) total outpatient visits, (ii) outpatient visits for gastrointestinal (GI) symptoms, and (iii) number of medications for GI symptoms. More severe abdominal pain was also significantly predictive of GI-related emergency department visits. Altered bowel habits were not consistent predictors of health care utilization. DISCUSSION: Severity of abdominal pain and depressive symptoms, but not bowel habits, is a primary driver of increased care-seeking behavior in patients with IBS, FC, and FDr.

BACKGROUND: Abdominal bloating is common in functional gastrointestinal disorders (FGID). To better characterize this patient population, we evaluated clinical and psychological characteristics of bloating and analyzed their differences by bloating severity. METHODS: Patients with FGIDs evaluated at a single academic outpatient referral gastroenterology clinic were surveyed. Bloating severity was classified as minimal, moderate or severe. Symptom-specific questionnaires were used to evaluate bowel habits, abdominal bloating, depression, anxiety, somatization and sleep disturbance. Associations between bloating severity, clinical characteristics and FGID subtypes were analyzed in univariate and multivariate modeling. KEY RESULTS: Of 612 FGID patients included (78% female, mean age of 44 ± 16.5 years), bloating was reported as minimal in 231(37.8%), moderate in 217(35.4%), or severe in 164(26.8%). Patients with severe bloating were more likely to be female, younger, and have co-existing functional dyspepsia than those with minimal bloating (p < 0.05). Bloating severity and severity of abdominal distension were significantly correlated (p < 0.05). On multivariable regression, patients who met criteria for functional constipation and functional dyspepsia had 80% and 125% higher odds, respectively, of severe bloating compared to minimal to moderate bloating. Younger age, abdominal pain and constipation severity, and somatization scores were also independently associated with severity of bloating. CONCLUSIONS & INFERENCES: Severe bloating is associated with younger age, and with more severe abdominal pain, constipation, and somatization. Patients who met criteria for functional constipation and functional dyspepsia are more likely to experience severe bloating.
