Determinants of Healthcare Utilization Among Veterans with Inflammatory Bowel Disease

Abdominal pain is associated with an increased risk of future healthcare resource utilization in inflammatory bowel disease

BACKGROUND

Numerous factors influence healthcare resource utilization (HRU) in inflammatory bowel disease (IBD). We previously demonstrated an association between the presence of certain IBD-related symptoms and HRU. We conducted a longitudinal study to identify the clinical variables and IBD-related symptoms predictive of HRU.

METHODS

This investigation utilized clinical encounters at an IBD center within a tertiary care referral center between 10/29/2015-12/31/2019. Participants were assessed over two time points (index and follow-up office visits) separated by a minimum of 6 months. Demographics, endoscopic disease severity, totals and sub-scores of surveys assessing for IBD-related symptoms, HRU, and substance use, and IBD-related medications. HRU was defined as any IBD-related emergency room visit, hospitalization, or surgery during the 6 months prior to follow-up appointment. We identified patients exhibiting HRU (at follow-up) and computed descriptive statistics and contingency table analyses of index appointment clinical data to identify predictors of HRU. Multivariable logistic regression models were fit incorporating significant demographic and clinical factors.

RESULTS

162 consecutively enrolled IBD patients (mean age 44.0 years; 99f:63 m; 115 Crohn's disease [CD], 45 ulcerative colitis [UC], 2 indeterminate colitis) were included. 121 patients (74.7%) exhibited HRU (mean age 43.6 years; 73f:48 m; 84 CD, 36 UC, 1 IC) preceding follow-up appointment. Abdominal pain (OR = 2.18, 95% CI 1.04-4.35, p = 0.04) at the index appointment was the only study variable significantly associated with HRU on bivariate analysis (Table 1). However, none of the clinical factors evaluated in this study were independently associated with HRU in our multivariable logistic regression model.

CONCLUSIONS

In this longitudinal study, abdominal pain was the only clinical variable that demonstrated an association with future HRU (even when considering other symptoms and key variables such as disease activity, IBD-medications, and psychiatric comorbidities (i.e., anxious or depressed state). These findings reinforce the importance of regularly screening for and effectively treating abdominal pain in IBD.

Creation of an Inflammatory Bowel Disease Referral Pathway for Identifying Patients Who Would Benefit From Inflammatory Bowel Disease Specialist Consultation

BACKGROUND

Recommendations regarding signs and symptoms that should prompt referral of patients with inflammatory bowel disease (IBD) to an IBD specialist for a consultation could serve to improve the quality of care for these patients. Our aim was to develop a consult care pathway consisting of clinical features related to IBD that should prompt appropriate consultation.

METHODS

A scoping literature review was performed to identify clinical features that should prompt consultation with an IBD specialist. A panel of 11 experts was convened over 4 meetings to develop a consult care pathway using the RAND/UCLA Appropriateness Method. Items identified via scoping review were ranked and were divided into major and minor criteria. Additionally, a literature and panel review was conducted assessing potential barriers and facilitators to implementing the consult care pathway.

RESULTS

Of 43 features assessed, 13 were included in the care pathway as major criteria and 15 were included as minor criteria. Experts agreed that stratification into major criteria and minor criteria was appropriate and that 1 major or 2 or more minor criteria should be required to consider consultation. The greatest barrier to implementation was considered to be organizational resource allocation, while endorsements by national gastroenterology and general medicine societies were considered to be the strongest facilitator.

CONCLUSIONS

This novel referral care pathway identifies key criteria that could be used to triage patients with IBD who would benefit from IBD specialist consultation. Future research will be required to validate these findings and assess the impact of implementing this pathway in routine IBD-related care.

Symptoms associated with healthcare resource utilization in the setting of inflammatory bowel disease

Several symptoms have been connected to increased healthcare resource utilization (HRU) in the context of inflammatory bowel disease (IBD), including both Crohn's disease (CD) and ulcerative colitis (UC). This study was designed to investigate the prevalence of IBD-associated symptoms and to determine whether any are independently associated with HRU. We undertook a retrospective analysis of data related to consecutive IBD patient encounters from a tertiary care referral center between 1/1/2015 and 8/31/2019. Demographics, clinical activity, endoscopic severity, IBD-related symptom scores, anxiety and depression scores, and other key clinical data were abstracted. Four hundred sixty-seven IBD patients [247f.: 220 m; 315 CD, 142 UC and 11 indeterminate colitis] were included in this study. The most common symptoms were fatigue (83.6%), fecal urgency (68.2%) and abdominal pain (63.5%). Fatigue, abdominal pain, anxiety or depression, corticosteroids, and opioids were each positively associated with HRU, while NSAID and mesalamine use were inversely associated on bivariate analysis. The only factor that demonstrated a statistically significant association with HRU in the whole cohort on multivariable analysis was abdominal pain. Abdominal pain is independently associated with HRU and should be specifically screened for in IBD patients to identify individuals at risk of undergoing expensive interventions. This study also reinforces the importance of optimizing diagnostic and therapeutic management of abdominal pain in IBD.

Racial disparity in healthcare utilization among patients with Irritable Bowel Syndrome: results from a multicenter cohort

BACKGROUND

Racial disparity in healthcare is defined as differences in healthcare services received by racial groups not due to difference in needs or preferences. As irritable bowel syndrome (IBS) is highly correlated with social factors, healthcare disparities are important factors in the sociocultural model of IBS. We used healthcare utilization as a lens to examine potential racial disparities in IBS.

METHODS

We retrospectively matched 3823 IBS minority patients who self-identified as "Hispanic," "Black," or "Asian" to white IBS controls and examined the number of patients with gastroenterology consults, gastroenterology procedures, and IBS-related Primary Care visits within each cohort from 2003 to 2017.

KEY RESULTS

Minority IBS patients were less likely to receive a gastroenterology consult than white IBS controls. Both Black and Asian IBS patients were more likely to have an IBS-related Primary Care visit than white IBS controls. All 3 minority IBS cohorts received significantly more gastroenterology procedures compared to white IBS controls.

CONCLUSIONS & INFERENCES

Minority IBS patients are more likely to receive gastroenterology procedures than white IBS patients. Further studies are needed to determine whether increased procedure likelihood in minority IBS patients represents a communication gap between minority patients and their providers or patient preference.

A Phenome-Wide Analysis of Healthcare Costs Associated with Inflammatory Bowel Diseases

INTRODUCTION

Crohn's disease (CD) and ulcerative colitis (UC) are associated with considerable direct healthcare costs. There have been few comprehensive analyses of all IBD- and non-IBD comorbidities that determine direct costs in this population.

METHODS

We used data from a validated cohort of patients with inflammatory bowel disease (IBD). Total healthcare costs were estimated as a sum of costs associated with IBD-related hospitalizations and surgery, imaging (CT or MR scans), outpatient visits, endoscopic evaluation, and emergency room (ER) care. All ICD-9 codes were extracted for each patient and clustered into 1804 distinct phecode clusters representing individual phenotypes. A phenome-wide association analysis (PheWAS) was performed using logistic regression to identify predictors of being in the top decile of costs.

RESULTS

Our cohort is comprised of 10,721 patients with IBD among whom 50% had CD. The median age was 46 years. The median total cost per patient is $11,203 (IQR $2396-30,563). The strongest association with total healthcare costs was intestinal obstruction without mention of hernia (p = 5.93 × 10^-156) and other intestinal obstruction (p = 9.24 × 10^-131). In addition, strong associations were observed for symptoms consistent with severity of IBD including the presence of fluid-electrolyte imbalance (p = 1.90 × 10^-130), hypovolemia (p = 1.65 × 10^-114), abdominal pain (p = 7.29 × 10^-60), and anemia (p = 1.90-10^-83). Cardiopulmonary diseases and psychological comorbidity also demonstrated significant associations with total costs with the latter being more strongly associated with ER visit-related costs.

CONCLUSIONS

Surrogate markers suggesting possible irreversible bowel damage and active disease demonstrate the greatest influence on IBD-related healthcare costs.

Clinical Characteristics of Inflammatory Bowel Disease Patients Requiring Long-Term Parenteral Support in the Present Era of Highly Effective Biologic Therapy

BACKGROUND

Despite advances in the medical management of inflammatory bowel disease (IBD), a subset of patients may require extensive surgery, leading to short-bowel syndrome/intestinal failure requiring long-term home parenteral nutrition (PN) or customized intravenous fluid (IVF) support. Our aim was to further define the characteristics of IBD patients requiring home PN/IVF.

METHODS

This is an observational study from a prospective IBD research registry. Patients receiving long-term home PN/IVF support during 2009-2015 were identified and compared with remaining IBD patients. Demographics, surgical history, smoking, narcotic use, IBD treatment, healthcare charges, and presence of biomarkers were reviewed. The IBD-PN group was stratified into 3 groups based on median healthcare charges.

RESULTS

Of 2359 IBD patients, there were 25 (1%, 24 with Crohn's disease) who required home PN/IVF, and 250 randomly selected IBD patients matched for disease type formed the control population. Median duration of PN use was 27 months (interquartile range, 11-66). PN use was significantly associated with smoking, narcotic use, IBD-related operations, and lower quality-of-life scores. Among IBD-PN patients, 7 of 25 (28%, 3 after use of teduglutide) were able to successfully discontinue this modality. Median healthcare charges in the IBD-PN group were $51,456 annually. Median charges in the controls were $3427. Period prevalence mortality was 11.5% in IBD-PN and 3.8% in controls.

CONCLUSIONS

IBD patients requiring long-term home PN/IVF support are a small minority in the present era of immunomodulator/biologic therapy. These refractory patients have a 15-fold increase in annual median healthcare charges compared with control IBD patients.

Predictors of High Health Care Utilization in Patients With Inflammatory Bowel Disease Within 1 Year of Establishing Specialist Care

BACKGROUND

A small proportion of patients with inflammatory bowel disease (IBD) consume a disproportionate amount of health care resources, with most of these spent on unplanned care in emergency room (ER) and hospital visits. Interventions in those at high risk in the outpatient setting could reduce the need for future inpatient care. We sought to describe the characteristics predictive of high health care utilization within 1 year after an initial IBD clinic encounter.

METHODS

This was a retrospective study of new IBD patients seen at the outpatient clinics of 2 tertiary IBD centers in the United States. Baseline sociodemographic and clinical characteristics were collected, and the number of IBD-related ER and hospital visits were recorded over the 1-year period after the initial clinic encounter. Patients with ≥2 visits (high utilizers) were compared with those with no visits.

RESULTS

Of the 735 patients included in the final analysis, 106 (14.4%) were high utilizers, and they had a mean of 2.9 visits (maximum = 10) in the 1 year after their initial encounter. In multivariate analysis, insurance coverage through medical assistance (odds ratio [OR] 3.57; 95% confidence interval [CI], 1.38-9.20), steroid use (OR 1.83; 95% CI, 1.11-3.04), short inflammatory bowel disease questionnaire score <50 (OR 2.29; 95% CI, 1.23-4.27), and current ostomy (OR 4.82; 95% CI, 1.51-15.37) were independently associated with high utilization.

CONCLUSIONS

Multidisciplinary care and resources should be preferentially channeled towards new clinic patients with severe disease and on medical assistance, as this could reduce future inpatient visits and result in cost savings.

Disease-Associated Costs in Children With Inflammatory Bowel Disease: A Systematic Review

BACKGROUND

As a chronic noncurable disorder often diagnosed in childhood or adolescence, inflammatory bowel disease (IBD) confers a significant financial lifetime burden. The objective of this systematic review was to determine the disease-associated costs (both direct and indirect) associated with IBD in children and young adults.

METHODS

We conducted a systematic review of the literature and included any study reporting direct health services-related costs or the indirect economic burden of IBD in persons aged ≤19 years (PROSPERO protocol number CRD2016036128). A technical panel of experts in pediatric gastroenterology and research methodology formulated the review questions, reviewed the search strategies and review methods, and provided input throughout the review process.

RESULTS

Nine studies met criteria for inclusion, 6 of which examined direct costs, 1 of which examined both direct and indirect costs, 1 of which assessed indirect costs, and 1 of which assessed out-of-pocket (OOP) costs. Inflammatory bowel disease-associated costs were significantly higher compared with costs in non-IBD populations, with wide variations in cost estimates, which prevented us from conducting a meta-analysis. Costs in Crohn's disease were higher than in ulcerative colitis. Overall, direct costs shifted from inpatient hospitalization as a major source of direct costs to medications, mainly driven by anti-tumor necrosis factor agents, as the leading cause of direct costs. Predictors of high costs included uncontrolled disease, corticosteroid treatment in the previous year, and comorbidity burden.

CONCLUSIONS

The pediatric literature examining IBD-attributable costs is limited, with widely variable cost estimates. There is a significant knowledge gap in the research surrounding indirect costs and OOP expenses.

Albumin nano-encapsulation of caffeic acid phenethyl ester and piceatannol potentiated its ability to modulate HIF and NF-kB pathways and improves therapeutic outcome in experimental colitis

Hypoxia inducible factor and nuclear factor-kappa beta pathways have been proposed as therapeutic targets for several inflammatory diseases. Caffeic acid phenethyl ester (CAPE) and piceatannol (PIC) are natural anti-inflammatory compounds; however, poor bioavailability and limited understanding of biomolecular mechanistic limits its clinical use. The aims of this study are to enhance bioavailability and investigate their impact on nuclear p65 and HIF-1α for the first time in experimental colitis.Dextran sulphate sodium was used to induce colitis in mice and effect of either free CAPE/PIC or CAPE/PIC loaded albumin nanoparticles treatment was observed on disease development and levels of cellular p65 and HIF-1α.Our results indicate that albumin nano-encapsulation of CAPE/PIC not only enhances its anti-inflammatory potential but also potentiates its ability to effectively modulate inflammation related biomolecular pathways. Hence, combining nanotechnology with natural compounds could result in development of new therapeutic options for IBD.

Index Severity Score and Early Readmission Predicts Increased Mortality in Ulcerative Colitis Patients

BACKGROUND

Readmissions are common after hospitalization related to ulcerative colitis (UC). A risk score to stratify the severity of UC hospitalizations and risk of colectomy has been previously reported. Our aim was to predict hospital-related outcomes after hospitalizations for UC utilizing this severity score.

METHODS

We utilized the Nationwide Readmissions Database (2010-2014) for hospitalized patients with UC and differentiated patients by index severity (low, intermediate, high). Baseline characteristics, surgical rates, readmissions, mortality, and hospital outcomes were collected. The primary outcomes of interest included readmission and mortality rates.

RESULTS

There were 133,819 patients admitted with UC with 22,762 (17%) readmitted within 30 days. Those readmitted within 30 days had a 4.5% calendar year mortality rate, compared with 0.45% in those not readmitted within 30 days (P < 0.001). Index surgery rates (19.2% vs 12.3%), length of stay (6.9 vs 5.4 days), and hospital costs ($13,530 vs $10,366; P < 0.001 for all) were higher in those readmitted within 30 days. Patients with high-severity presentations had higher surgical rates (31.6%), higher 30-day and calendar year readmission rates (24.3% and 46.0%, respectively), increased index and calendar year mortality (2.5% and 2.0%, respectively), longer length of stay (15.1 days), and increased costs ($31,136) compared with those with low severity (P < 0.001 for all). Calendar-year survival rates in those with intermediate and high scores were significantly lower than in those with low scores.

CONCLUSIONS

An index severity score of intermediate or high and early readmissions are predictors of calendar year mortality. Future efforts should emphasize more focused care in high-risk patients, as this may reduce readmissions and improve outcomes.

Elderly-Onset and Adult-Onset Ulcerative Colitis Are More Similar than Previously Reported in a Nationwide Cohort

BACKGROUND

Elderly-onset ulcerative colitis (EO-UC) is recognized as a distinct subpopulation of UC. To our knowledge, there have been no nationwide studies of EO-UC populations in the USA.

AIMS

We aim to characterize differences in presentation at diagnosis and clinical course between EO-UC and adult-onset UC (AO-UC) patients in a national cohort.

METHODS

Complete medical records of patients newly diagnosed with UC from October 2001 to October 2011 in the Veterans Affairs health system were obtained. Patients were followed until colectomy, death, or the end of the observation period on November 2015. EO-UC patients (age of diagnosis ≥65 years) were compared to AO-UC patients (age of diagnosis ≤40 years) with respect to demographic, severity, and therapeutic data. Statistical analysis was performed using JMP statistical software.

RESULTS

We identified 836 newly diagnosed UC patients, of which 207 had EO-UC and 102 had AO-UC. The mean age of diagnosis was 72.4 years (EO-UC) and 32.9 years (AO-UC), with a mean 8-year follow-up period. The incidence of pancolitis at the time of diagnosis was similar between both groups (p = 0.67). There was no difference in steroid use (36.7 vs 45.1%, p = 0.1563), thiopurine use (19.3 vs 22.6%, p = 0.5081), and colectomy rates (6.3 vs 5.9%, p = 0.8911) between EO-UC and AO-UC populations. There was lower anti-TNF use in EO-UC patients compared to AO-UC patients (5.8 vs 14.7%, p = 0.0091).

CONCLUSION

In this nationwide cohort, we found that the use of steroids, thiopurines, and colectomy was similar in both populations, while anti-TNF use was lower among the elderly.
