Race Differences in Initial Presentation, Early Treatment, and 1-year Outcomes of Pediatric Crohn's Disease: Results from the ImproveCareNow Network

Racial and ethnic differences in diagnosis age and blood biomarkers in a pediatric inflammatory bowel disease cohort

OBJECTIVE

Prompt diagnosis of pediatric-onset inflammatory bowel disease (IBD) is crucial for preventing a complicated disease course; however, it is not well understood how social determinants of health might affect pediatric IBD diagnosis. This study examined differences in diagnosis age, biomarkers of disease severity, and anthropometrics with sociodemographic factors in a pediatric IBD cohort.

METHODS

Pediatric IBD patients (n = 114) and their parents/caregivers were enrolled from the Children's of Alabama Pediatric IBD Clinic in Birmingham, Alabama. Primary analyses examined associations of child race and ethnicity, parental income, parental education, single-parent household status, insurance type, and distance to a tertiary pediatric gastroenterology referral center with diagnosis age. Secondary analyses examined differences in biomarker levels, height, and body mass index at the time of diagnosis.

RESULTS

Racial and ethnic minority children were diagnosed at an older age compared to Non-Hispanic White children (14.4 ± 0.40 vs. 11.7 ± 0.38 years; p < 0.001), and this trend was robust to adjustment with other sociodemographic variables. Parental attainment of a college education attenuated the link between minority race and ethnicity and the likelihood of older age at diagnosis, while other sociodemographic variables had no moderating effect. Racial and ethnic minority children were 5.7 times more likely to have clinically elevated erythrocyte sedimentation rate at diagnosis compared to Non-Hispanic White children (p = .024).

CONCLUSIONS

These results suggest that child race and ethnicity may exert a primary effect on the age at diagnosis with pediatric-onset IBD. This study highlights the need for further research on racial and ethnic disparities to promote health equity in pediatric-onset IBD.

Child Health Needs and the Pediatric Gastroenterology Workforce: 2020-2040

This article is part of an American Board of Pediatrics Foundation-sponsored effort to analyze and forecast the pediatric subspecialty workforce between 2020 and 2040. Herein, an overview of the current pediatric gastroenterology workforce is provided, including demographics, work characteristics, and geographic distribution of practitioners. Brief context is provided on the changing nature of current practice models and the increasing prevalence of some commonly seen disorders. On the basis of a rigorous microsimulation workforce projection model, projected changes from 2020 to 2040 in the number of pediatric gastroenterologists and clinical workforce equivalents in the United States are presented. The article closes with a brief discussion of training, clinical practice, policy, and future workforce research implications of the data presented. This data-driven analysis suggests that the field of pediatric gastroenterology will continue to grow in scope and complexity, propelled by scientific advances and the increasing prevalence of many disorders relevant to the discipline. The workforce is projected to double by 2040, a growth rate faster than most other pediatric subspecialties. Disparities in care related to geography, race, and ethnicity are among the most significant challenges for the years ahead. Changes to training and education, incentives to meet the needs of underserved populations, and new multidisciplinary models for health care delivery will be necessary to optimally meet the volume, diversity, and complexity of children with gastroenterological diseases in the years ahead.

Racial Disparities in Pediatric Inflammatory Bowel Disease Care: Differences in Outcomes and Health Service Utilization Between Black and White Children

OBJECTIVE

To describe racial inequities in pediatric inflammatory bowel disease care and explore potential drivers.

METHODS

We undertook a single-center, comparative cohort study of newly diagnosed Black and non-Hispanic White patients with inflammatory bowel disease, aged <21 years, from January 2013 through 2020. Primary outcome was corticosteroid-free remission (CSFR) at 1 year. Other longitudinal outcomes included sustained CSFR, time to anti-tumor necrosis factor therapy, and evaluation of health service utilization.

RESULTS

Among 519 children (89% White, 11% Black), 73% presented with Crohn's disease and 27% with ulcerative colitis. Disease phenotype did not differ by race. More patients from Black families had public insurance (58% vs 30%, P < .001). Black patients were less likely to achieve CSFR 1-year post diagnosis (OR: 0.52, 95% CI:0.3-0.9) and less likely to achieve sustained CSFR (OR: 0.48, 95% CI: 0.25-0.92). When adjusted by insurance type, differences by race to 1-year CSFR were no longer significant (aOR: 0.58; 95% CI: 0.33, 1.04; P = .07). Black patients were more likely to transition from remission to a worsened state, and less likely to transition to remission. We found no differences in biologic therapy utilization or surgical outcomes by race. Black patients had fewer gastroenterology clinic visits and 2-fold increased odds for emergency department visits.

CONCLUSIONS

We observed no differences by race in phenotypic presentation and medication usage. Black patients had half the odds of achieving clinical remission, but a degree of this was mediated by insurance status. Understanding the cause of such differences will require further exploration of social determinants of health.

Racial and Ethnic Variation in Presentation, Diagnosis, Treatment, and Outcome of Pediatric Crohn Disease: A Single Center Study

OBJECTIVES

Disparities in health care for racial/ethnic minority children in the United States who are burdened by pediatric Crohn's disease (PCD) are not well understood.

METHODS

A retrospective review of the Texas Children's Hospital ImproveCareNow database from 2007 to 2015 was performed. CD patients with a minimum of 2-year follow-up were included if the onset of symptoms attributable to inflammatory bowel disease was clearly documented. We primarily aimed to identify race and ethnicity associations in diagnostic delay, presentation, treatment, and 2-year outcomes. We also examined early versus late diagnosis (ie, over 6 months from disease onset) associations with these variables unrelated to race/ethnicity.

RESULTS

One hundred and sixty-six PCD patients [57.8% non-Hispanic White (NH-White), 18.1% African American (AA), and 15.7% Hispanic] met selection criteria. Time to diagnosis was shorter in Hispanic patients ( P < 0.01) and they were older at diagnosis than NH-White patients ( P = 0.0164). AA patients (33%, P < 0.01) and Hispanic patients (35%, P < 0.05) had lower rates of granuloma detection than NH-White patients (63%). AA patients had lower rates of steroid-free remission (SFR) at 2 years than NH-White patients ( P < 0.05). Higher ESR and lower hemoglobin levels were associated with early diagnosis ( P < 0.01). Early diagnosis was associated with higher rates of surgery within 2 years of diagnosis ( P < 0.05). Diagnostic fecal calprotectin levels inversely associated with SFR at 2 years ( P < 0.05). Early use of biologics positively, and early use of corticosteroids negatively correlated with 2-year SFR ( P < 0.05).

CONCLUSIONS

Race and ethnicity may influence the diagnosis, treatment, and outcomes of PCD. This recognition presents a nidus toward establishing equity in PCD care.

Racial and Ethnic Distribution of Inflammatory Bowel Disease in the United States

BACKGROUND

The current burden of Crohn's disease (CD) and ulcerative colitis (UC) in minority populations is largely unknown. We sought to evaluate the relative prevalence of CD and UC across racial and ethnic groups within the National Patient-Centered Clinical Research Network (PCORnet).

METHODS

We queried electronic health records from 337 centers from January 2013 to December 2018. We compared the relative prevalence of CD and UC across racial/ethnic groups to the general PCORnet populations using χ 2 and univariable logistic regression.

RESULTS

Among 39,864,077 patients, 114,168 had CD, and 98,225 had UC. Relative to the overall PCORnet population, Black adult patients were significantly less likely than White patients to have a diagnosis of CD (odds ratio [OR], 0.53; 95% CI, 0.52-0.54) or UC (OR, 0.41; 95% CI, 0.40-0.43). Pediatric Black patients were also less likely to have a diagnosis of CD (OR, 0.41; 95% CI, 0.39-0.43) or UC (OR, 0.38; 95% CI, 0.35-0.41). Adult Hispanic patients were less likely to have a diagnosis of CD (OR, 0.33; 95% CI, 0.32-0.34) or UC (OR, 0.45; 95% CI, 0.44-0.46) compared with non-Hispanic patients. Similarly, pediatric Hispanic patients were less likely to have a diagnosis of CD (OR, 0.34; 95% CI, 0.32-0.36) or UC (OR, 0.50; 95% CI, 0.47-0.53).

CONCLUSIONS

Despite the increasing racial and ethnic diversity in the United States, these data suggest that CD and UC are modestly less prevalent among patients of non-White races and Hispanic ethnicity.

Disease-Specific Health Disparities: A Targeted Review Focusing on Race and Ethnicity

Background: Wide disparities in health status exist in the United States across race and ethnicity, broadly driven by social determinants of health—most notably race and ethnic group differences in income, education, and occupational status. However, disparities in disease frequency or severity remain underappreciated for many individual diseases whose distribution in the population varies. Such information is not readily accessible, nor emphasized in treatment guidelines or reviews used by practitioners. Specifically, a summary on disease-specific evidence of disparities from population-based studies is lacking. Our goal was to summarize the published evidence for specific disease disparities in the United States so that this knowledge becomes more widely available “at the bedside”. We hope this summary stimulates health equity research at the disease level so that these disparities can be addressed effectively. Methods: A targeted literature review of disorders in Pfizer’s current pipeline was conducted. The 38 diseases included metabolic disorders, cancers, inflammatory conditions, dermatologic disorders, rare diseases, and infectious targets of vaccines under development. Online searches in Ovid and Google were performed to identify sources focused on differences in disease rates and severity between non-Hispanic Whites and Black/African Americans, and between non-Hispanic Whites and Hispanics. As a model for how this might be accomplished for all disorders, disparities in disease rates and disease severity were scored to make the results of our review most readily accessible. After primary review of each condition by one author, another undertook an independent review. Differences between reviewers were resolved through discussion. Results: For Black/African Americans, 29 of the 38 disorders revealed a robust excess in incidence, prevalence, or severity. After sickle cell anemia, the largest excesses in frequency were identified for multiple myeloma and hidradenitis suppurativa. For Hispanics, there was evidence of disparity in 19 diseases. Most notable were metabolic disorders, including non-alcoholic steatohepatitis (NASH). Conclusions: This review summarized recent disease-specific evidence of disparities based on race and ethnicity across multiple diseases, to inform clinicians and health equity research. Our findings may be well known to researchers and specialists in their respective fields but may not be common knowledge to health care providers or public health and policy institutions. Our hope is that this effort spurs research into the causes of the many disease disparities that exist in the United States.

Reduced Systemic Corticosteroid Use among Pediatric Patients With Inflammatory Bowel Disease in a Large Learning Health System

OBJECTIVES

Corticosteroids have long been used to treat inflammatory bowel disease. However, cumulative corticosteroid exposure is associated with adverse effects, particularly in growing children. Professional guidelines recommend steroid-sparing strategies. It remains unknown whether corticosteroid use has decreased in children with inflammatory bowel disease.

METHODS

We performed retrospective cohort study using data from 2007 to 2018 from the international multi-center ImproveCareNow Network, a pediatric inflammatory bowel disease quality improvement collaborative. Pediatric patients diagnosed with inflammatory bowel disease were included. Patients with missing diagnosis or corticosteroid use data were excluded. We performed serial cross-sectional analyses of period prevalence and used multivariate regression models.

RESULTS

27,321 patients were included (65% Crohn disease, 28% ulcerative colitis, 7% indeterminate colitis). Corticosteroids were used in 10,206 (37%). Corticosteroid use decreased from 28% (2007) to 12% (2018). Black patients received corticosteroids more commonly than white patients. This disparity improved as corticosteroid use decreased in both groups. Most corticosteroid use occurred <120 days after diagnosis. Corticosteroid or 5-aminosalicylate use <120 days after diagnosis predicted later corticosteroid use. Anti-tumor necrosis factor-alpha medication use <120 days after diagnosis was associated with a reduction in corticosteroid use. As corticosteroid use decreased, steroid-sparing therapy use increased and height and weight z scores improved, particularly among children with Crohn disease. Despite improvement across the network, variation in corticosteroid usage remains.

CONCLUSIONS

Corticosteroid use among pediatric patients with inflammatory bowel disease in the ImproveCareNow Network has decreased over time. Racial disparities in corticosteroid use were found, but gradually improved.

Black Race and Public Insurance Are Predictive of Inappropriate Evaluation of Iron Deficiency Anemia and Diarrhea

BACKGROUND AND AIMS

Socioeconomic status, race, and insurance can impact healthcare delivery and utilization in several chronic disease states. The primary aim of our study was to determine whether race and insurance status are predictors of having an appropriate workup for celiac disease and inflammatory bowel disease (IBD) when presenting with iron deficiency anemia (IDA) and chronic diarrhea.

METHODS

Medical records of patients seen at the University of Chicago Medical Center between January 1, 2006, and September 20, 2017, were reviewed. Patients with two separate encounters within 6 months associated with the diagnosis codes for both IDA and chronic diarrhea were identified. Patients without a diagnosis code for IBD and celiac disease were further grouped as those that had an "appropriate" workup and those that did not. Factors associated with the appropriate evaluation were analyzed by univariate and multivariate logistic regression.

RESULTS

In total, 899,701 records were searched. A total of 83 patients fit inclusion into the study (8 IBD, 3 CD, 72 neither IBD or CD). Black race was associated with a 91% decreased odds of having the appropriate workup on univariate (OR 0.090, 95%CI 0.017-0.475, p = 0.005) and age-adjusted multivariate analysis (OR 0.095, 95% CI 0.017-0.527, p = 0.007). Public insurance status was significantly associated with a 90% decreased odds of appropriate workup on univariate (OR 0.102, 95% CI 0.024-0.438, p = 0.002) and age-adjusted multivariate analysis (OR 0.104, 95% CI 0.021-0.513, p = 0.005).

CONCLUSIONS

Black race and public insurance were significantly associated with not having an appropriate workup for IBD and celiac disease when presenting with iron deficiency and chronic diarrhea.

Disparities in Objective Sleep Quality as Assessed Through Wrist Actigraphy in Minority Patients With Inflammatory Bowel Disease

BACKGROUND

Inflammatory bowel disease (IBD) is associated with a reduced quality of life. Minority patients with IBD specifically report more impairing symptoms compared with nonminority patients. Sleep quality, a key component of quality of life, is significantly compromised in minority patients compared with nonminority patients. Nevertheless, subjective and objective sleep assessments in minority patients with IBD have not explicitly been assessed. The purpose of this prospective cohort study is to assess and compare objective sleep parameters utilizing wrist actigraphy between minority and nonminority IBD patients.

METHODS

In this institutional review board approved study, 74 patients with IBD were recruited and stratified into 2 cohorts by self-identification: white nonminority patients and minority patients. Patients in the minority cohort included black and Hispanic individuals (black and nonblack). Exclusion criteria included significant comorbidity, a history of an underlying sleep disorder, or patients who did not self-identify into categorized cohorts. Sleep was measured not only through wrist-based actigraphy but also with sleep surveys. Sleep parameters were compared between minority and nonminority cohorts. Regression analyses were performed to assess for factors independently associated with parameters of poor sleep quality.

RESULTS

Sixty-four patients (86.4%) were included in the final analysis. Thirty-one individuals (48.4%) were categorized into the nonminority cohort, and 33 (51.6%) patients were in the minority cohort. A significantly higher number of minority patients had poorer sleep efficiency and fragmented sleep compared with nonminority patients (90.9% vs 67.7%; P = 0.03 and 87.8% vs 61.3%; P = 0.02). In the adjusted analysis, minority status was independently associated with poor sleep efficiency (odds ratio = 6.41; 95% confidence interval, 1.48-28.17; P = 0.0139) and fragmented sleep (odds ratio = 4.98; 95% confidence interval, 1.09-22.89; P = 0.0389).

CONCLUSIONS

Minority patients with IBD were shown to have poorer objective measures of sleep as assessed through wrist actigraphy compared to nonminority patients. Cultural competency in the care of minority patients with IBD, specifically focusing on the management of psychosocial issues, is needed to address these disparities in sleep. The inclusion of minority patients with IBD in studies investigating sleep and other psychosocial issues are warranted not only to assess potential disparities in disease course but also to determine the etiologies of poor sleep in minority patients with IBD.

What Are the Most Challenging Aspects of Inflammatory Bowel Disease? An International Survey of Gastroenterologists Comparing Developed and Developing Countries

Background and Aims

As inflammatory bowel disease (IBD) becomes more prevalent, the challenges that gastroenterologists face in managing these patients evolve. We aimed to describe the most important challenges facing gastroenterologists from around the world and compare these between those working in developed and developing countries.

Methods

An online questionnaire was developed, and a link distributed to gastroenterologists. Data were analyzed descriptively using Friedman and Wilcoxon matched-pair signed rank tests to compare rankings for responses. Mann-Whitney U tests were used to compare rankings between responses from gastroenterologists from developed and developing countries. Lower scores reflected greater challenges.

Results

Of 872 who started, 397 gastroenterologists (45.5%) completed the survey. Respondents represented 65 countries (226 [56.9%] from developed countries). Overall, the challenge ranked most important (smallest number) was increasing IBD prevalence (13.6%). There were significant differences in mean ranking scores for many simple aspects of care for those from developing countries compared to providers from developed countries, such as access to simple IBD treatments (5.52 vs. 6.02, p = 0.01), access to anti-TNF drugs including dose escalation (3.33 vs. 3.93, p < 0.01), access to good stoma care (2.57 vs. 3.03, p < 0.001), access to therapeutic drug monitoring (1.47 vs. 1.84, p < 0.001), and access to care for people from low socioeconomic status (2.77 vs. 3.37, p < 0.001).

Conclusions

Increasing IBD prevalence is seen by gastroenterologists as the greatest challenge facing them. There are significant differences between the IBD challenges facing gastroenterologists from developed and developing countries that reflect inequities in access to health care.

Abdominal Pain After Pediatric Inflammatory Bowel Disease Diagnosis: Results From the ImproveCareNow Network

OBJECTIVES

Although abdominal pain is a hallmark symptom of pediatric inflammatory bowel disease (IBD), limited research has examined pain during the first year after diagnosis. The purpose of the present study is to examine prevalence, predictors, and impact of abdominal pain during the 12 months after pediatric IBD diagnosis using data from the ImproveCareNow (ICN) Network.

PATIENTS AND METHODS

Participants consisted of 13,875 youth (age 8-18 years, 44% female, 81% Caucasian) with IBD (65% Crohn's disease; 27% ulcerative colitis, 8% indeterminate colitis) enrolled in the ICN Network with data from clinic visits during the first year after diagnosis (1-22 visits; mean = 3.7). Multivariable mixed effects logistic regression models were conducted to analyze the presence versus the absence of abdominal pain, activity limitations, and decrements in well-being.

RESULTS

The percentage of youth reporting abdominal pain decreased significantly during the first year after diagnosis and yet a sizeable group reported continued pain at 12 months (55.9% at diagnosis; 34.0% at 12 months). Multivariable analyses revealed that greater time since diagnosis (odds ratio [OR] = 0.98, P < 0.001), higher disease severity (OR = 11.84, P < 0.001), presence of psychosocial risk factors (OR = 2.33, P = 0.036), and female sex (OR = 1.90, P < 0.010) were significant correlates of continuing abdominal pain. Abdominal pain was significantly associated with decrements in well-being (OR = 5.11, P < 0.001) as well as limitations in activity (OR = 9.31, P < 0.001), over and above the influence of disease severity.

CONCLUSIONS

Abdominal pain is prevalent and impactful, even when controlling for disease activity, during the first year after pediatric IBD diagnosis. Results from the present study can inform screening and tailored pain management intervention efforts in pediatric IBD.

Socioeconomic disparities in the comorbidities and surgical management of pediatric Crohn's disease

BACKGROUND

To examine differences in comorbidities and surgical management based on socioeconomics in hospitalized children with Crohn's disease (CD).

METHODS

Using the Kids' Inpatient Database for 2006-2012, we identified patients (<21 years) with a CD diagnosis. Cases were analyzed and stratified by median parental income by zip code. Multivariable logistic regression was performed.

RESULTS

Of the 28,337 pediatric CD hospitalizations identified, patients were more likely male (51.1%), non-Hispanic white (71.3%), and had a mean age of 15.9 years. The proportion of minority patients increased as income quartile declined. Higher income quartile patients were more likely to be coded with anxiety and less likely with anemia. The highest income quartile was more likely to have a bowel obstruction, and peritoneal/intestinal abscess and was also 28% more likely to undergo a major surgical procedure.

CONCLUSIONS

Significant variability exists in the reported comorbidities and surgical interventions associated with CD by income quartile. Lower income quartile patients are more likely to be of minority ethnicity and anemic, but less likely to undergo a major surgical procedure. Further investigation is warranted to determine whether these differences represent disease variability, differences in healthcare resource allocation, or implicit bias in management.

IMPACT

There is a disparity in the care of children and young adults with Crohn's disease based on parental income. Links between parental income and the treatment of Crohn's disease in children and young adults has not been assessed in national datasets in the United States. Children in the highest income quartile were more likely to undergo a major surgical procedure. The variations in healthcare for hospitalized children and young adults with CD found in this study may represent variability in patient disease, implicit bias, or a disparity in healthcare delivery across the United States.

Black/African American Patients with Pediatric Crohn's Disease Report Less Anxiety and Fatigue than White Patients

OBJECTIVES

To compare patient-reported outcomes in black/African American patients with white patients participating in IBD Partners Kids & Teens, in order to identify possible racial healthcare disparities in pediatric inflammatory bowel disease (IBD) as future targets for improvement.

STUDY DESIGN

This was a cross-sectional analysis comparing patient-reported outcomes in black/African American patients with white patients, aged 9-18 years, with IBD participating in the IBD Partners Kids & Teens cohort from August 2013 to April 2018. Secondary outcomes included number of IBD-related hospitalizations and surgeries, current medication use, and disease activity.

RESULTS

We included 401 patients with Crohn's disease (white = 378 [94%]; black/African American = 23 [6%]). For children with Crohn's disease, black/African American patients compared with white patients reported less anxiety (40.7 vs 47.5, P = .001) and fatigue (44.3 vs 48.4, P = .047) despite more frequently reported treatment with biologics (91% vs 61%, P = .006) and antibiotics (17% vs 5%, P = .03) and history of hospitalizations (81% vs 52%, P = .02).

CONCLUSIONS

Black/African American children with Crohn's disease were less likely to report anxiety or fatigue than white patients, despite an apparent more severe disease course reflected by greater reported frequency of treatment with biologics and antibiotics and history of hospitalizations.

Quality improvement in healthcare for patients with inflammatory bowel disease

Since inflammatory bowel diseases (IBD) are chronic disorders with typical remission and relapses and no cure, maintaining high quality of provided healthcare to patients with IBD plays a major role in the management and reducing disease-related morbidity. To hone process-based quality indicators in order to ameliorate quality of care, the indicators must be based on high quality evidence and expert consensus. ImproveCareNow (ICN) group gave us a great example of quality improvement (QI) by gaining experience in how to exercise, apply and implement QI methods in the care of children with IBD. "The American Gastroenterological Association" has developed an adult "IBD physician performance measures set" and both "Crohn's and Colitis Foundation of America" (CCFA) and "Crohn's and Colitis Canada" (CCC) have developed sets of most highly rated process and outcome measures. "The Emerging Practice in IBD Collaborative (EPIC) Canadian group" developed definitions of quality indicators for best-practice management of IBD in Canada. "Quality of Care through the Patient's Eyes (QUOTE-IBD)" was honed as a questionnaire to quantify quality of care in the eyes of patients with IBD. This is now widely used in several European countries. The current concepts of quality of care as well as quality indicators will be discussed in this article.

A comparison of the risk of postoperative recurrence between African-American and Caucasian patients with Crohn's disease

BACKGROUND

Many patients with Crohn's disease will develop complications that require surgery. Recurrence after surgery is common.

AIM

To assess racial differences in postoperative recurrence between African-Americans and Caucasians.

METHODS

Medical records of Crohn's disease patients who underwent surgery (ileal, colonic, or ileocolonic resection) between June 2014 and June 2016 were reviewed. The primary endpoints were clinical and endoscopic remission at 6-12 months after a Crohn's disease surgery. Secondary outcomes included biological and histologic remission. Risks of recurrence were assessed by univariate, multivariate, and propensity score-matched analysis.

RESULTS

Thirty-six African-American and 167 Caucasian patients with Crohn's disease were included for analysis. There was no difference in disease location, disease behaviour, type of surgery performed, and pre- or postoperative medication use between the two groups. The rate of endoscopic remission did not differ between African-American and Caucasian patients (50% vs 42%, P = 0.76), and race did not influence the risk of endoscopic recurrence on univariate, multivariate, or propensity score-matched analysis. The rate of clinical remission was significantly lower in African-American patients compared to Caucasian patients (36% vs. 63%, P = 0.008). African-American race was significantly associated with clinical recurrence on univariate (odds ratio (OR) 6.76, 95% CI 1.50-30.40; P = 0.01), multivariate (OR 5.02, 95% CI 1.60-15.80; P = 0.006), and propensity-matched analysis (68% vs. 32% in Caucasians, P = 0.005). Rates of biologic and histologic remission were similar between the two groups on all analyses.

CONCLUSIONS

We found that African-American patients with Crohn's disease have a similar degree of objective measures of mucosal inflammation after surgery including endoscopic recurrence as compared to Caucasian patients. However, African-American race was significantly associated with clinical recurrence, suggesting the presence of ethnic variation in postoperative presentation in Crohn's disease.

Minority Pediatric Patients with Inflammatory Bowel Disease Demonstrate an Increased Length of Stay

BACKGROUND

Genetic and other biological factors may lead to differences in disease behavior among children with inflammatory bowel disease of different races, which may be further modified by disparities in care delivery. Using the Kids' Inpatient Database, we aimed to evaluate differences in the management of pediatric patients with inflammatory bowel disease by race, focusing on length of stay (LOS).

METHODS

We performed a cross-sectional analysis using 2000 to 2012 data from the Kids' Inpatient Database, a nationally representative database. We identified pediatric patients (≤18 years of age) with discharge diagnoses of Crohn's disease (CD) or ulcerative colitis (UC). We used multivariable logistic regression to evaluate the relationship between race and LOS, controlling for age, payer status need for surgery, and year of admission.

RESULTS

We identified 27,295 hospitalizations for children with inflammatory bowel disease (62% CD and 38% UC), Compared with white patients with CD, black (adjusted odds ratio 1.37; 95% confidence interval, 1.22-1.53; P < 0.001) and Hispanic patients (adjusted odds ratio: 1.37; 95% confidence interval: 1.19-1.59; P < 0.001) with CD demonstrated increased odds of a LOS greater than the 75th percentile. When compared with white patients with UC, Hispanic patients also demonstrated increased odds of a LOS greater than the 75th percentile (adjusted odds ratio: 1.20; 95% confidence interval, 1.02-1.42, P = 0.015).

CONCLUSIONS

After controlling for age, year of admission, and clinical phenotypes, black and Hispanic patients with CD and Hispanic patients with UC had longer LOS than white patients. These may be due to differences in provider/hospital characteristics, socioeconomic differences, and/or differences in genetics and other biological factors (see Video Abstract, Supplemental Digital Content 1, http://links.lww.com/IBD/B656).
