Healthcare spending and utilization for pediatric Irritable Bowel Syndrome in a commercially insured population.

BACKGROUND: Pediatric Irritable Bowel Syndrome (IBS) is common and can be associated with disabling gastrointestinal symptoms. Comprehensive data regarding utilization and cost of pediatric IBS are lacking. Our aim was to determine the annual all-cause spending and healthcare utilization in pediatric IBS. METHODS: Cross-sectional cohort study using a national claims database of commercially insured individuals. 932,592 members, age 8-18 years, were included. Members were selected based on PheWas codes and continuous enrollment in 2014. Linear and binomial regression models were used to calculate healthcare spending and compare comorbidities between IBS subjects and controls. KEY RESULTS: 1215 members with claims for IBS (68.4% female) and 931,377 controls (55.7% female) were included. Mean age was 15.03 ± 2.83 (median 16) years in the IBS group and 13.14 ± 3.12 (median 13) years in controls. Mental health and chronic pain comorbidities were more prevalent in the IBS cohort. Healthcare spending: The mean annual all-cause incremental spending of members with IBS was $6,364.60 compared to controls when adjusting for age and gender. Healthcare utilization: Members with IBS had increased healthcare utilization including higher rates of inpatient, outpatient, and emergency room visits, and higher rates of health service utilization including medical care, radiology/laboratory services, surgery, anesthesia, mental health, and physical therapy. General pediatrics was more frequently consulted by controls. All subspecialty consultations, with the exception of dental medicine and endocrinology, were sought more frequently by IBS patients. CONCLUSION: Patients with IBS incur significant annual spending through increased healthcare utilization.

Functional Luminal Imaging Probe Assessment in Postfundoplication Patients Changes Management Beyond Manometry.

OBJECTIVES: Fundoplication is a commonly performed pediatric surgery but the surgery can result in nonspecific symptoms that merit further evaluation. The goal of this study was to determine the utility of Functional Luminal Imaging Probe (FLIP) compared with high-resolution manometry with impedance (HRIM) in the evaluation of fundoplication symptoms. METHODS: We reviewed the FLIP and HRIM tracings of symptomatic fundoplication patients. We compared FLIP results of fundoplication patients to those of pediatric achalasia and control patients. We also compared the role of FLIP to HRIM in clinical decision-making and clinical outcomes. RESULTS: EGJ distensibilities of fundoplication patients ranged from 0.6 to 8.2 mm/mmHg. Because of the different pediatric patient sizes (8.9--73.5 kg), balloon size inflations varied but, after adjusting balloon fill volume by weight, there was a linear relationship between inflation and distensibility. When compared with control patients and achalasia patients, distensibilities of fundoplication patients were lower than control patients and higher than achalasia patients (P = 0.0001). Patients who had an EGJ intervention had a mean EGJ distensibility of 2.3 ±â€Š1.1 mm/mmHg compared with 5.1 ±â€Š1.6 mm/mmHg in medically managed patients (P = 0.0001). Patients who had an esophagogastric junction (EGJ) intervention had a mean IRP of 13.9 ±â€Š6.1 mmHg compared with medically managed patients who had a mean IRP of 9.9 ±â€Š3.9 mmHg (P = 0.3). CONCLUSIONS: We show FLIP may provide additional insight into EGJ physiology in symptomatic fundoplication patients and complements HRIM.

Emergency department burden of constipation in the United States from 2006 to 2011.

OBJECTIVES: Although constipation is typically managed in an outpatient setting, there is an increasing trend in the frequency of constipation-related hospital visits. The aim of this study was to analyze trends related to chronic constipation (CC) in the United States with respect to emergency department (ED) visits, patient and hospital characteristics, and associated costs. METHODS: Data from 2006 to 2011, in which constipation (The International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnosis codes 564.00-564.09) was the primary discharge diagnosis, were obtained from the National Emergency Department Sample (NEDS). RESULTS: Between 2006 and 2011, the frequency of constipation-related ED visits increased by 41.5%, from 497,034 visits to 703,391 visits, whereas the mean cost per patient rose by 56.4%, from $1,474 in 2006 to $2,306 in 2011. The aggregate national cost of constipation-related ED visits increased by 121.4%, from $732,886,977 in 2006 to $1,622,624,341 in 2011. All cost data were adjusted for inflation and reported in 2014 dollars. Infants (<1 year old) had the highest rate of constipation-related ED visits in both 2006 and 2011. The late elders (85+ years) had the second highest constipation-related ED visit rate in 2006; however, the 1- to 17-year-old age group experienced a 50.7% increase in constipation-related ED visit rate from 2006 to 2011 and had the second highest constipation-related ED visit rate in 2011. CONCLUSIONS: The frequency of and the associated costs of ED visits for constipation are significant and have increased notably from 2006 to 2011.

Health-related quality of life in pediatric patients with functional and organic gastrointestinal diseases.

OBJECTIVE: To compare health-related quality of life (HRQOL) in pediatric patients with functional gastrointestinal disorders (FGIDs) and organic gastrointestinal (GI) diseases with an age-, sex-, and race/ethnicity-matched healthy sample across GI diagnostic groups and with one another. STUDY DESIGN: The Pediatric Quality of Life Inventory 4.0 Generic Core Scales were completed in a 9-site study by 689 families. Patients had 1 of 7 physician-diagnosed GI disorders: chronic constipation, functional abdominal pain, irritable bowel syndrome, functional dyspepsia, Crohn's disease, ulcerative colitis, and gastroesophageal reflux disease. The healthy control sample included 1114 families. School days missed, days in bed and needing care, parent missed workdays, work impact, and healthcare utilization were compared as well. RESULTS: Patients with an FGID or organic GI disease demonstrated lower HRQOL than the healthy controls across all dimensions (physical, emotional, social, and school; P < .001 for all), with larger effect sizes for patients with an FGID. Patients with an FGID manifested lower HRQOL than those with an organic GI disease. Patients with an FGID or organic GI disease missed more school, spent more days in bed and needing care, had greater healthcare utilization, and had parents who missed more workdays with greater work impact (P < .001 for most), with larger effect sizes for the patients with an FGID. CONCLUSION: Patients with an FGID or organic GI disease demonstrate impaired HRQOL compared with healthy children. HRQOL can be used as a common metric to compare patient outcomes in clinical research and practice both within and across groups of patients with FGIDs and organic GI diseases.

Assessment of abdominal pain through global outcomes and recent FDA recommendations in children: are we ready for change?

OBJECTIVES: Irritable bowel syndrome is a multisymptom construct, with abdominal pain (AP) acting as the driving symptom of patient-reported severity. The Food and Drug Administration considers a >30% decrease in AP as satisfactory improvement, but this has not been validated in children. We investigated the correspondence of 2 measures for AP assessment, ≥30% improvement in AP and global assessment of improvement. METHODS: Secondary analysis of data from 72 children who completed a randomized clinical trial for abdominal pain-associated functional gastrointestinal disorders. Children completed daily assessment of AP intensity, functional disability inventory (FDI), question regarding pain's interference with activities, and 2 global assessment questions. We measured the extent to which ≥30% improvement of AP and global assessment questions correlated with each other and with disability. RESULTS: The global questions correlated with each other (r=0.74; P<0.0001) and with a ≥30% improvement in AP (P<0.01). Global outcomes were satisfaction with treatment was inversely related to the child's report of interference with activities (P<0.01) and symptom relief was positively associated with ≥30% improvement in FDI scores (P<0.009). A 30% change in FDI scores was associated with global questions of symptom relief (P=0.009) but not with satisfaction with treatment (P=0.07). The association of AP improvement with interference with activities (P=0.14) or change in FDI scores (P=0.27) did not reach significance. CONCLUSIONS: Currently used global assessments are significantly associated with decreased pain intensity, decreased interference with daily activities, and a ≥30% change in FDI scores, whereas recommended 30% improvement in pain intensity is not as comprehensive.
