Prevalence of chronic narcotic use among children with inflammatory bowel disease

Psychiatric Disorders in Adult and Paediatric Patients With Inflammatory Bowel Diseases - A Systematic Review and Meta-Analysis

BACKGROUND

Inflammatory bowel diseases [IBD], which are associated with a high disease burden, are also reported to be accompanied by a high prevalence of psychiatric disorders. However, the literature on IBD and psychiatric disorders has not been reviewed.

METHODS

This systematic review followed the PRISMA guidelines, and its protocol was registered at PROSPERO [ID: CRD42020214359]. PubMed, Embase and PsycINFO were consulted for the literature search. Studies reporting on diagnosed psychiatric disorders in IBD were included. Pooled prevalence rates were calculated using random effects meta-analyses. Study quality was assessed using the Newcastle-Ottawa Scale [NOS].

RESULTS

Sixty-nine studies were identified with an average cohort size of 60 114 patients. Pooled prevalence rates were: mood disorders, 10% (95% confidence interval [CI] = 7%; 15%); anxiety disorders, 12% [95% CI = 8%; 18%]; substance misuse, 3% [95% CI = 1%; 7%]; psychotic disorders, 2% [95% CI = 1%; 4%]; behavioural disorders, 1% [95% CI = 0%; 3%]; personality disorders, 3% [95% CI = 1%; 10%]; developmental disorders, 1% [95% CI = 0%; 3%]; and behavioural and emotional disorders with onset usually during childhood, 1% [95% CI = 1%; 3%]. All analyses had high statistical heterogeneity [I2 > 99%]. Seven studies reported an increased risk of suicide in IBD patients compared to controls.

CONCLUSION

The prevalence of psychiatric comorbidities was high [11-82%] in patients with IBD and was higher than in the background population. Addressing mental health problems in patients with IBD can improve their adherence to treatment and the somatic disease course and, consequently, reduce morbidity and mortality.

Psychiatric comorbidity in childhood onset immune-mediated diseases-A systematic review and meta-analysis

AIM

To estimate psychiatric comorbidity in childhood onset immune-mediated inflammatory diseases (IMID).

METHODS

The PRISMA guidelines were followed, and the protocol was registered at Prospero (ID: CRD42021233890). Literature was searched in PubMed, PsycINFO and Embase. Original papers on prevalence rates of diagnosed psychiatric disorders and/or suicide in paediatric onset inflammatory bowel disease (pIBD), rheumatic diseases (RD) and autoimmune liver diseases were selected. Pooled prevalence rates of psychiatric disorders (grouped according to ICD-10 criteria) within the various IMID were calculated using random-effects meta-analysis. Risk of bias was evaluated by the Newcastle-Ottawa scale.

RESULTS

Twenty-three studies were included; 13 describing psychiatric disorders in pIBD and 10 in RD. Anxiety and mood disorders were mostly investigated with pooled prevalence rates in pIBD of 6% (95% confidence interval (CI): 4%-9%) and 4% (95%CI: 2%-8%), respectively, in register-based studies, and 33% (95%CI: 25%-41%) and 18% (95%CI: 12%-26%), respectively, in studies using psychiatric assessment. In RD, rates were 13% (95%CI: 12%-15%) for anxiety disorders and 20% (95%CI: 15%-26%) for mood disorders based on psychiatric assessment.

CONCLUSION

Anxiety and depression are commonly reported in childhood onset IMID. Physicians should be attentive to mental health problems in these patients as they seem overlooked.

Polypharmacy in Patients With Inflammatory Bowel Disease: Prevalence and Outcomes in a Single-center Series

BACKGROUND

Polypharmacy can complicate the course and management of chronic diseases, and has been little explored in patients with inflammatory bowel disease (IBD) to date.

AIM

The aim of this study was to determine the prevalence of polypharmacy in a series of IBD patients, describing associated factors and its correlation with poor disease outcomes.

MATERIALS AND METHODS

Retrospective study of a single-center series. Polypharmacy was defined as the simultaneous use of 5 or more drugs. Disease outcomes, IBD treatment nonadherence and undertreatment were evaluated at 1 year.

RESULTS

A total of 407 patients were included [56% males, median age: 48 y (interquartile range, 18 to 92 y)], of whom 60.2% had Crohn's disease; Chronic comorbidity and multiple comorbidities were present in 54% and 27% of patients, respectively. Median number of prescriptions per patient was 3 (range: 0 to 15). Polypharmacy was identified in 18.4% of cases, inappropriate medication in 10.5% and use of high-risk drugs in 6.1% (mainly opioids). In multivariate analysis, polypharmacy was associated with chronic comorbidity [odds ratio (OR)=10.1, 95% confidence interval (CI): 2.14-47.56; P˂0.003], multiple comorbidities (OR=3.53, 95% CI: 1.46-8.51; P=0.005) and age above 62 years (OR=3.54, 95% CI: 1.67-7.51; P=0.001). No association with poor disease outcomes was found at 12 months. However, polypharmacy was the only factor associated with IBD treatment nonadherence (OR=2.24, 95% CI: 1.13-4.54, P=0.02).

CONCLUSIONS

Polypharmacy occurs in around 1 in 5 patients with IBD, mainly in older adults and those with comorbidity. This situation could interfere with adherence to IBD treatment and therapeutic success.

Emerging Comorbidities in Inflammatory Bowel Disease: Eating Disorders, Alcohol and Narcotics Misuse

Inflammatory bowel disease (IBD) is a chronic and potentially devastating condition of the digestive tract which is exemplified by increasing prevalence worldwide, byzantine pathogenesis with a poorly defined role of the environmental factors, and complex clinical demonstration. As a systemic disease, IBD may progress with a wide spectrum of extraintestinal manifestations (EMs) and comorbidities affecting different organs and systems, from anaemia, undernutrition, and cancer to those which are often neglected like anxiety and depression. Evolving IBD epidemiology and changing environment are reflected by an expanding list of IBD-related comorbidities. In contrast to the well-established role of smoking the connection between alcohol and IBD is still debatable on many levels, from pathogenesis to complications. Furthermore, little is known about narcotics use in IBD patients, even if there are obvious factors that may predispose them to narcotics as well as alcohol misuse. Last but not least, the question arises what is the prevalence of eating disorders in IBD. In our paper, we aimed to discuss the current knowledge on alcohol and drugs misuse and eating disorders as emerging extraintestinal comorbidities in IBD.

Interventions for the management of abdominal pain in ulcerative colitis

BACKGROUND

Ulcerative colitis (UC) is a chronic inflammation of the colon characterised by periods of relapse and remission. It starts in the rectum and can extend throughout the colon. UC and Crohn's disease (CD) are the most common inflammatory bowel diseases (IBDs). However, UC tends to be more common than CD. It has no known cure but can be managed with medication and surgery. However, studies have shown that abdominal pain persists in up to one-third of people with UC in remission. Abdominal pain could be a symptom of relapse of the disease due to adverse effects of medication, surgical complications and strictures or adhesions secondary to UC.

OBJECTIVES

To assess the efficacy and safety of interventions for managing abdominal pain in people with ulcerative colitis.

SEARCH METHODS

We searched CENTRAL, MEDLINE and five other databases and clinical trials registries on 28 April 2021. We contacted authors of relevant studies and ongoing or unpublished trials that may be relevant to the review. We also searched references of trials and systematic reviews for any additional trials.

SELECTION CRITERIA

All published, unpublished and ongoing randomised trials that compared interventions for the management of abdominal pain with other active interventions or standard therapy, placebo or no therapy were included. People with both active and inactive disease were included. We excluded studies that did not report on any abdominal pain outcomes.

DATA COLLECTION AND ANALYSIS

Two review authors independently conducted data extraction and 'Risk of bias' assessments. We analysed data using Review Manager 5. We expressed dichotomous and continuous outcomes as risk ratios (RRs) and mean differences (MDs), respectively, with 95% confidence intervals. We assessed the certainty of the evidence using the GRADE methodology.

MAIN RESULTS

We included five studies (360 randomised participants). Studies considered mainly participants in an inactive state of the disease.   No conclusions could be drawn about the efficacy of any of the interventions on pain frequency, pain intensity, and treatment success. The certainty of the evidence was very low for all comparisons because of imprecision due to sparse data, and risk of bias. One study compared a low FODMAPs diet (n=13) to a sham diet (n=13). The evidence is very uncertain about the effect of this treatment on pain frequency (MD -4.00, 95% CI -20.61 to 12.61) and intensity (MD -9.00, 95% CI -20.07 to 2.07). Treatment success was not reported. One study compared relaxation training (n=20) to wait-list (n=20). The evidence is very uncertain about the effect of this treatment on pain frequency at end of intervention (MD 2.60, 95% CI 1.14 to 4.06) and 6-month follow-up (MD 3.30, 95% CI 1.64 to 4.96). Similarly, the evidence is very uncertain about the effect of this treatment on pain intensity at end of intervention (MD -1.70, 95% CI -2.92 to -0.48) and 6-month follow-up (MD -2.30, 95% CI -3.70 to -0.90). Treatment success was not reported. One study compared yoga (n=30) to no intervention (n=30). The study defined treatment success as the presence or absence of pain; however, the data they provided was unclear. Pain frequency and intensity were not reported. One study compared a kefir diet (Lactobacillus bacteria, n=15) to no intervention (n=15). The evidence is very uncertain about the effect of this treatment on pain intensity (MD -0.17, 95% CI -0.91 to 0.57). Pain frequency and treatment success were not reported. One study compared a stellate ganglion block treatment (n=90) to sulfasalazine treatment (n=30). The study defined treatment success as "stomachache"; however, the data they provided was unclear. Pain frequency and intensity were not reported. Two studies reported withdrawals due to adverse events. One study reported withdrawals due to adverse events as zero. Two studies did not report this outcome.  We cannot draw any conclusions about the effects of any of the interventions on withdrawals due to adverse events because of the very limited evidence. The reporting of secondary outcomes was inconsistent. Adverse events tended to be very low or zero. However, we can make no clear judgements about adverse events for any of the interventions, due to the low number of events. Anxiety was measured and reported at end of intervention in only one study (yoga versus no intervention), and depression was not measured in any of the studies. We can therefore draw no meaningful conclusions about these outcomes.

AUTHORS' CONCLUSIONS

We found very low-certainty evidence on the efficacy and safety of interventions for the management of abdominal pain in ulcerative colitis. Pervasive issues with very serious imprecision from small samples size and high risk of bias have led to very low-certainty outcomes, precluding conclusions. While few adverse events and no serious adverse events were reported, the certainty of these findings was again very low for all comparisons, so no conclusions can be drawn. There is a need for further research. We have identified eight ongoing studies in this review, so an update will be warranted. It is key that future research addresses the issues leading to reduced certainty of outcomes, specifically sample size and reporting that leads to high risk of bias. It is also important that if researchers are considering pain as a critical outcome, they should report clearly if participants were pain-free at baseline; in that case, data would be best presented as separate subgroups throughout their research.

Opioid prescribing to preteen children undergoing ambulatory surgery in the United States

BACKGROUND

Overuse and misuse of opioids is a continuing crisis. The most common reason for children to receive opioids is postoperative pain, and they are often prescribed more than needed. The amount of opioids prescribed varies widely, even for minor ambulatory procedures. This study uses a large national sample to describe filled opioid prescriptions to preteen patients after all ambulatory surgical procedures and common standard procedures.

METHODS

We analyzed Truven Health MarketScan data for July 2012 through December 2016 to perform descriptive analyses of opioid fills by age and geographic area, change over time, second opioid fills in opioid-naïve patients, and variation in the types and amount of medication prescribed for 18 common and standard procedures in otolaryngology, urology, general surgery, ophthalmology, and orthopedics.

RESULTS

Over 10% of preteen children filled perioperative opioid prescriptions for ambulatory surgery in the period 2012 to 2016. The amount prescribed varied widely (median 5 days' supply, IQR 3-8, range 1-90), even for the most minor procedures, for example, frenotomy (median 4 days' supply, IQR 2-5, range 1-60). Codeine fills were common despite safety concerns. Second opioid prescriptions were filled by opioid-naïve patients after almost all procedures studied. The rate of prescribing declined significantly over time and varied substantially by age and across census regions.

CONCLUSIONS

We identified opioid prescribing outside of the norms of standard practice in all of the specialties studied. Standardizing perioperative opioid prescribing and developing guidelines on appropriate prescribing for children may reduce the opioids available for misuse and diversion.

Substance use disorders among youth with chronic physical illness

This study estimated prevalence of substance use disorder in youth with chronic physical illness; quantified magnitudes of association between different chronic physical illnesses with substance use disorder; and, tested whether mental disorder moderates these associations. Data come from 6,377 individuals aged 15-30 years in the Canadian Community Health Survey-Mental Health. Alcohol, cannabis, or other drug use disorder measured using the WHO Composite International Diagnostic Interview 3.0. Individuals with chronic physical illness were more likely to have other drug use disorder compared to healthy controls (2.4% vs. 1.3%; p < .001), but not more likely to have alcohol (7.8% vs. 6.8%) or cannabis use disorder (5.0% vs. 3.6%). Odds of alcohol use disorder were higher among individuals with musculoskeletal conditions, OR = 1.41 (1.03-1.93), but lower among individuals with neurological conditions, OR = 0.49 (0.33-0.72), compared to healthy controls. No associations were found for cannabis use disorder. Odds of other drug use disorder were higher among individuals with endocrine conditions, OR = 2.88 (1.37-6.06). In the presence vs. absence of major depressive disorder, odds for substance use disorder were higher among individuals with respiratory or endocrine conditions. However, odds were lower among individuals with comorbid neurological and major depressive disorders or comorbid respiratory and generalized anxiety disorders. The complexity of the association between chronic physical illness and substance use disorder is compounded when accounting for the moderating effect of mental disorder, which in some contexts, results in a reduced likelihood of substance use disorder in youth with chronic physical illness.

Evaluation of Opioid Use in Acute Pancreatitis in Absence of Chronic Pancreatitis: Absence of Opioid Dependence an Important Feature

BACKGROUND

Chronic opioid use and dependence is common in patients with chronic pancreatitis. Patients with acute pancreatitis are frequently treated with opioids, but their risk for ongoing use is not well known. The aim of our study is to characterize opioid use in patients after an episode of acute pancreatitis and to assess persistent, chronic, and daily opioid use in such patients in the absence of chronic pancreatitis.

METHODS

This is a single-center review of prospectively enrolled patients with acute pancreatitis. Using the Massachusetts Prescription Awareness Tool, we recorded all opioid prescriptions (ie, frequency, duration, and amount) for patients from December 2016 to September 2019, after index hospitalization for acute pancreatitis. Patients with chronic pancreatitis were excluded. We used univariate and multivariate analysis to determine predictors of opioid use at discharge and subsequent follow-up over 18 months.

RESULTS

Of 235 enrolled patients who were opioid-naïve, 123 patients (52.3%) received opioids at discharge after index hospitalization. In follow-up over 18 months, 40 patients (17.0%) received additional opioid prescriptions. These patients had more severe disease, longer length of stay, and higher pain score at discharge. Patients with prior history of acute pancreatitis, local complications, and higher pain scores were twice as likely to subsequently be prescribed opioids. Persistent opioid use was seen only in recurrent acute pancreatitis. There was no daily or chronic opioid use.

CONCLUSIONS

In the absence of chronic pancreatitis, there was no daily or chronic use of opioids in patients with acute pancreatitis. Persistent use was only seen in patients with recurrent acute pancreatitis. These patients are at increased risk of chronic opioid use and dependence.

Biopsychosocial Correlates of Presence and Intensity of Pain in Adolescents With Inflammatory Bowel Disease

Background: There is growing consensus that pain in pediatric inflammatory bowel disease (IBD) is not fully explained by disease-related processes. However, previous studies have largely measured individual biological, psychological, or social risk factors for pain in isolation. Further, not all youth with IBD presenting to clinic will report presence of pain, and those who do vary in their reports of pain intensity. This study therefore extends prior research by determining biopsychosocial correlates of both presence and intensity of pain in adolescents with IBD, in order to inform targeted pain management intervention approaches. Methods: Adolescents with IBD followed at SickKids, Toronto, and their parents were consecutively enrolled from outpatient clinic. IBD characteristics (diagnosis, time since diagnosis, patient-reported disease activity) were collected. Adolescents reported on current pain (NRS-10), internalizing symptoms (Strengths and Difficulties Questionnaire), and pain catastrophizing (Pain Catastrophizing Scale-Child). Parents reported on protective responses to child pain (Adult Responses to Child Pain) and pain catastrophizing (Pain Catastrophizing Scale-Child). Hurdle models were conducted to examine predictors of presence and intensity of pain in the same model. Biological (patient-reported disease activity, IBD diagnosis subtype, illness duration), psychological (internalizing symptoms, pain catastrophizing), and social (parent pain catastrophizing, parent protective responses) factors were entered as predictors, adjusting for age and sex. Results: Participants included 100 adolescents (12-18; Mean = 15 years) with IBD (60% Crohn's Disease, 40% Ulcerative Colitis or IBD-unclassified) and 76 parents. The majority of the sample was in clinical remission or reported minimal symptoms. Half of participants reported no current pain; for those reporting pain, intensity ranged 1-7 (M = 3.43, SD = 1.98). Disease activity (OR = 53.91, p < 0.001) and adolescent internalizing symptoms (OR = 7.62, p = 0.03) were significant predictors of presence of pain. Disease activity (RR = 1.37, p = 0.03) and parent protective responses (RR = 1.45, p = 0.02) were significant predictors of intensity of pain. Conclusions: Results suggest that the experience of pain in pediatric IBD is biopsychosocially determined. Patient-reported disease activity and internalizing symptoms predicted presence of pain, while disease activity and parent protective responses predicted intensity of pain. While medical intervention in pediatric IBD is focused on disease management, results suggest that depression/anxiety symptoms as well as parent protective responses may be important targets of pain management interventions in pediatric IBD.

Association of opioid use and peripheral artery disease

BACKGROUND

Prescription opioids account for 40% of all U.S. opioid overdose deaths, and national efforts have intensified to reduce opioid prescriptions. Little is known about the relationship between peripheral artery disease (PAD) and high-risk opioid use. The objectives of this study were to evaluate this relationship and to assess the impact of PAD treatment on opiate use.

METHODS

In this retrospective cohort study, the Truven Health MarketScan database (Truven Health Analytics, Ann Arbor, Mich), a deidentified national private insurance claims database, was queried to identify patients with PAD (two or more International Classification of Diseases, Ninth Revision diagnosis codes of PAD ≥2 months apart, with at least 2 years of continuous enrollment) from 2007 to 2015. Critical limb ischemia (CLI) was defined as the presence of rest pain, ulcers, or gangrene. The primary outcome was high opioid use, defined as two or more opioid prescriptions within a 1-year period. Multivariable analysis was used to determine risk factors for high opioid use.

RESULTS

A total of 178,880 patients met the inclusion criteria, 35% of whom had CLI. Mean ± standard deviation follow-up time was 5.3 ± 2.1 years. An average of 24.7% of patients met the high opioid use criteria in any given calendar year, with a small but significant decline in high opioid use after 2010 (P < .01). During years of high opioid use, 5.9 ± 5.5 yearly prescriptions were filled. A new diagnosis of PAD increased high opioid use (21.7% before diagnosis vs 27.3% after diagnosis; P < .001). A diagnosis of CLI was also associated with increased high opioid use (25.4% before diagnosis vs 34.5% after diagnosis; P < .001). Multivariable analysis identified back pain (odds ratio [OR], 1.89; 95% confidence interval [CI], 1.84-1.93; P < .001) and illicit drug use (OR, 1.87; 95% CI, 1.72-2.03; P < .001) as the highest predictors of high opioid use. A diagnosis of CLI was also associated with higher risk (OR, 1.61; 95% CI, 1.57-1.64; P < .001). A total of 43,443 PAD patients (24.3%) underwent 80,816 PAD-related procedures. After exclusion of periprocedural opioid prescriptions (4.9% of all opioid prescriptions), the yearly percentage of high opioid users increased from 25.8% before treatment to 29.6% after treatment (P < .001).

CONCLUSIONS

Patients with PAD are at increased risk for high opioid use, with nearly one-quarter meeting described criteria. CLI and treatment for PAD additionally increase high opioid use. In addition to heightened awareness and active opioid management, our findings warrant further investigation into underlying causes and deterrents of high-risk opioid use.

Challenges in Transitional Care in Inflammatory Bowel Disease: A Review of the Current Literature in Transition Readiness and Outcomes

Transitional care for patients with IBD focuses on efforts to successfully transfer care from pediatric to adult providers while encouraging the assumption of health care responsibility. As 25% of patients will be diagnosed with IBD before the age of 18 years, many will undergo this process. Efforts to enhance this process have included transition clinics and other means to improve patient comfort with transition and develop the skill of health care self-management. Currently, most pediatric practitioners provide transition care with informal education and emphasize independence without formal programs. A variety of tools to assess transition readiness have been developed. Given the varied disease process, often varied and subjective outcomes, and lack of studies such as randomized controlled trials, further data are necessary to determine the best avenue to transition and assess outcomes. Critically relevant to providing adequate care to transitioning patients includes understanding the development of self-management skills and the developmental processes relevant to young adults with IBD. Transition represents an area for quality improvement, and although progress has been made in recognition and promotion of transition practices, future directions in research will allow improved understanding of the evidence-based practices and needs of these individuals to further enhance their care.

Persistent Opioid Use Among Children, Adolescents, and Young Adults After Common Cleft Operations

BACKGROUND

Surgical care represents an important source of opioid prescribing and chronic use, but rates of prolonged opioid use following pediatric procedures remain unclear. The authors describe the rates and risk factors for new persistent opioid use in patients after common cleft operations.

METHODS

The authors examined claims from the Truven Marketscan databases from January 1, 2010 to December 31, 2014. The authors included opioid-naive patients ages 8 to 25, who underwent 1 of 10 cleft-related procedures. Patients were considered opioid-naïve if they had no opioid prescription fills in the 11 months prior to the perioperative period. The authors obtained a random sample of age-matched, nonsurgical patients from the same dataset to be used as a control group. Included cleft patients had no procedural codes in the 6 months following surgery. All included patients filled an opioid prescription during the perioperative period, defined as 30 days before and 14 days after surgery. The primary outcome was new persistent opioid use, which is defined as continued opioid prescription fills between 90 and 180 days after the procedure.

RESULTS

This cohort included 2039 cleft patients and 2100 control patients. The incidence of new persistent opioid use following surgery was 4.4% and 0.1% in the control group. Higher odds of opioid use 3 months beyond surgery were associated with distractor placement (OR 5.34, CI 2.00-14.24, P = 0.001). Increasing age (OR 1.11, CI 1.04-1.17, P = 0.001) and presence of a gastrointestinal comorbidity (OR 7.37, CI 1.49-36.54, P = 0.014) were also associated with new persistent use.

CONCLUSIONS

New persistent opioid use occurs after cleft-related procedures and could lead to chronic use in children, adolescents, and young adults.

Alcohol and narcotics use in inflammatory bowel disease

The aim of this study was to evaluate alcohol consumption and narcotics use among patients with inflammatory bowel diseases (IBD). A comprehensive literature search was conducted in Medline using relevant keywords. The references of the retrieved articles were also searched to identify additional articles. Only English-language studies that provided evidence on alcohol consumption and/or narcotics use among non-hospitalized IBD patients were included in the present review. Twelve studies were included that examined the use of alcohol among IBD patients. The prevalence of alcohol consumption among IBD patients appeared to be similar to that of the general population. The majority of the studies reported worsening of IBD symptoms among patients who consumed alcoholic beverages. Four studies were identified that evaluated narcotics use as analgesia among IBD patients. Narcotics use was prevalent among IBD patients and correlated with a longer disease duration and comorbid mental illnesses. The available evidence suggests that alcohol consumption may have a deleterious effect on IBD symptoms. Furthermore, a considerable proportion of IBD patients are reported to use a narcotic as analgesia and this was correlated with their mental health status. Further studies are needed to address these important facets of IBD.

Starting Young: Trends in Opioid Therapy Among US Adolescents and Young Adults With Inflammatory Bowel Disease in the Truven MarketScan Database Between 2007 and 2015

Background

Opioids are commonly prescribed for relief in inflammatory bowel disease (IBD). Emerging evidence suggests that adolescents and young adults are a vulnerable population at particular risk of becoming chronic opioid users and experiencing adverse effects.

Objectives

This study evaluates trends in the prevalence and persistence of chronic opioid therapy in adolescents and young adults with IBD in the United States.

Method

A longitudinal retrospective cohort analysis was conducted with the Truven MarketScan Database from 2007 to 2015. Study subjects were 15-29 years old with ≥2 IBD diagnoses (Crohn's: 555/K50; ulcerative colitis: 556/K51). Opioid therapy was identified with prescription claims within the Truven therapeutic class 60: opioid agonists. Persistence of opioid use was evaluated by survival analysis for patients who remained in the database for at least 3 years following index chronic opioid therapy use.

Results

In a cohort containing 93,668 patients, 18.2% received chronic opioid therapy. The annual prevalence of chronic opioid therapy increased from 9.3% in 2007 to 10.8% in 2015 (P < 0.01), peaking at 12.2% in 2011. Opioid prescriptions per patient per year were stable (approximately 5). Post hoc Poisson regression analyses demonstrated that the number of opioid pills dispensed per year increased with age and was higher among males. Among the 2503 patients receiving chronic opioid therapy and followed longitudinally, 30.5% were maintained on chronic opioid therapy for 2 years, and 5.3% for all 4 years.

Conclusion

Sustained chronic opioid use in adolescents and young adults with IBD is increasingly common, underscoring the need for screening and intervention for this vulnerable population.

Risk of post-operative surgical site infections after vedolizumab vs anti-tumour necrosis factor therapy: a propensity score matching analysis in inflammatory bowel disease

BACKGROUND

Perioperative vedolizumab (VDZ) and anti-tumour necrosis factor (TNFi) therapies are implicated in causing post-operative complications in inflammatory bowel disease (IBD).

AIM

To compare the risk of surgical site infections (SSIs) between VDZ- and TNFi-treated IBD patients in propensity-matched cohorts.

METHODS

The Optum Research Database was used to identify IBD patients who received VDZ or TNFi within 30 days prior to abdominal surgery between January 2015 and December 2016. The date of IBD-related abdominal surgery was defined as the index date. SSIs were determined by ICD-9/10 and CPT codes related to superficial wound infections or deep organ space infections after surgery. Propensity score 1:1 matching established comparable cohorts based on VDZ or TNFi exposure before surgery based on evidence-based risk modifiers.

RESULTS

The propensity-matched sample included 186 patients who received pre-operative biologic therapy (VDZ, n = 94; TNFi, n = 92). VDZ and TNFi cohorts were similar based on age, gender, IBD type, concomitant immunomodulator exposure, chronic opioid or corticosteroid therapy, Charlson Comorbidity Index and malnutrition. VDZ patients were more likely to undergo an open bowel resection with ostomy. After propensity score matching, there was no significant difference in post-operative SSIs (TNFi 12.0% vs VDZ 14.9%, P = 0.56). Multivariable analysis indicated that malnutrition was the sole risk factor for developing SSI (OR 3.1, 95% CI 1.11-8.71) regardless of the type of biologic exposure.

CONCLUSION

In the largest, risk-adjusted cohort analysis to date, perioperative exposure to VDZ therapy was not associated with a significantly higher risk of developing an SSI compared to TNFi therapy.

Opioid misuse in gastroenterology and non-opioid management of abdominal pain

Opioids were one of the earliest classes of medications used for pain across a variety of conditions, but morbidity and mortality have been increasingly associated with their chronic use. Despite these negative consequences, chronic opioid use is increasing worldwide, with the USA and Canada having the highest rates. Chronic opioid use for noncancer pain can have particularly negative effects in the gastrointestinal and central nervous systems, including opioid-induced constipation, narcotic bowel syndrome, worsening psychopathology and addiction. This Review summarizes the evidence of opioid misuse in gastroenterology, including the lack of evidence of a benefit from these drugs, as well as the risk of harm and negative consequences of opioid use relative to the brain-gut axis. Guidelines for opioid management and alternative pharmacological and nonpharmacological strategies for pain management in patients with gastrointestinal disorders are also discussed. As chronic pain is complex and involves emotional and social factors, a multimodal approach targeting both pain intensity and quality of life is best.

Maladaptive Coping and Depressive Symptoms Partially Explain the Association Between Family Stress and Pain-Related Distress in Youth With IBD

Objective

To extend existing research on the pain burden experienced by youth with inflammatory bowel disease (IBD) by examining the complexity of psychosocial factors involved in pain-related distress.

Methods

Parents completed measures of family stress and their child's pain-related expressions of distress and coping. Youth with IBD rated their depressive symptoms (n = 183 dyads). Mediation analyses were performed using regression-based techniques and bootstrapping.

Results

Greater family stress was positively related to children's pain-related expressions of distress and passive coping. Significant indirect effects were found in the relationship between family stress and expressed pain-related distress through parent-reported passive coping, depressive symptoms, and both passive coping and depressive symptoms sequentially.

Conclusions

Results suggest that family stress can place children at risk for greater expressed pain-related distress through effects on coping and depressive symptoms. Addressing psychosocial difficulties is important for closing the gap between disability and health in youth with IBD.

Trends in Narcotic and Corticosteroid Prescriptions in Patients with Inflammatory Bowel Disease in the United States Ambulatory Care Setting from 2003 to 2011

BACKGROUND/HYPOTHESIS

Before the availability of biological therapies, corticosteroids and narcotics were frequently used in patients with inflammatory bowel disease (IBD) because of a paucity of disease-modifying therapies. The increased accessibility to effective biologicals for IBD over the last decade should be leading to less use of corticosteroids and narcotic medications. This study aims to examine trends in prescriptions of corticosteroids and narcotics to patients with IBD in the United States during the period 2003 to 2011.

METHODS

Data from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey were used to examine visits of patients with IBD. Trends in corticosteroid and narcotic prescriptions were explored, and predictors of use were assessed using survey-weighted chi-square tests.

RESULTS

From 2003 to 2011, a total of 1119 patients with IBD had visits recorded in the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey databases. Although biological prescriptions significantly increased from 3.3% in 2003 to 2005 to 15.9% in 2009 to 2011 (P = 0.004), there was no significant decrease in corticosteroid or narcotic prescriptions during this same time frame. Patients with IBD were less likely to receive narcotics (odds ratio = 0.38) when seeing a medical specialist compared with primary care physicians or surgeons.

CONCLUSIONS

Despite the availability of more effective biological therapies, prescriptions for corticosteroids and narcotics did not decline in patients with IBD visiting U.S. ambulatory clinics and emergency departments from 2003 to 2011.
