Abstract
OBJECTIVES Treatment for adults diagnosed with binge-eating disorder (BED) includes psychotherapy and/or pharmacotherapy and aims to reduce the frequency of binge-eating episodes and disordered eating, improve metabolic-related issues and reduce weight, and address mood symptoms. Data describing real-world treatment patterns are lacking; therefore, this study aims to characterize real-world treatment patterns among patients with BED. METHODS This retrospective study identified adult patients with BED using natural language processing of clinical notes from the Optum electronic health record database from 2009 to 2015. Treatment patterns were examined during the 12 months preceding the BED recognition date and during a follow-up period after BED recognition (1-3 years for most patients). RESULTS Among 1042 patients, 384 were categorized as the BED cohort and 658, who met less stringent criteria, were categorized as probable BED. In the BED cohort, mean ± SD age was 45.2 ± 13.4 years and 81.8% were women (probable BED, 45.9 ± 12.8 years, 80.2%). A greater percentage of patients in the BED cohort were prescribed pharmacotherapy (70.6% [probable BED, 66.9%]) than received/discussed psychotherapy (53.1% [probable BED, 39.2%]) at baseline. In the BED cohort, 54.4% of patients were prescribed antidepressants (probable BED, 52.4%), 25.3% stimulants (probable BED, 20.1%), and 34.4% nonspecific psychotherapy (probable BED, 24.6%) at baseline, with no substantive differences observed during follow-up. Low percentages of patients in the BED cohort received/discussed cognitive behavioral therapy at baseline (12.5% [probable BED, 9.0%) or during follow-up (13.0% [probable BED, 8.8%). Among patients with ≥1 psychotherapy visit, the mean ± SD number of visits in the BED cohort was 1.2 ± 5.9 at baseline (probable BED, 1.7 ± 7.3) and 2.2 ± 7.7 during follow-up (probable BED, 2.6 ± 7.7). CONCLUSION This cohort of patients with BED was treated more frequently with pharmacotherapy than psychotherapy. These data may help inform strategies for reducing differences between real-world treatment patterns and evidence-based recommendations.

Abstract
OBJECTIVE To estimate relative suicidality risk associated with binge-eating disorder (BED). METHODS Retrospective study of patients identified as having BED (N = 1042) and a matched general population cohort (N = 10,420) from the Optum electronic health record database between January 2009 and September 2015. Patients had ≥1 outpatient encounter with a provider who recognized BED during the 12-month baseline preceding entry date. Incidence and relative risk of suicidality were assessed. RESULTS Incidence per 1000 person-years (95% CI) of suicidal ideation and suicide attempts, respectively, was 31.1 (23.1, 41.0) and 12.7 (7.9, 19.4) in the BED cohort and 5.8 (4.7, 7.1) and 1.4 (0.9, 2.2) in the comparator cohort. Risk of suicidal ideation and suicide attempts was greater in the BED cohort (HR [95% CIs], 6.43 [4.42, 9.37]) than in the comparator cohort (HR [95% CI], 9.47 [4.99, 17.98]) during follow-up. After adjusting for psychiatric comorbidities, associations of suicidal ideation and suicide attempts with BED remained elevated in patients with BED having histories of suicidality. CONCLUSIONS Findings suggest that history of suicidality may result in an increased risk of suicidal ideation and suicide attempts in patients with BED relative to the general population. Psychiatric comorbidity burden may explain the elevated risk of these conditions in BED.

Abstract
Objective: To evaluate annual concomitant psychotropic medication use among stimulant-treated children/adolescents with ADHD. Method: Children/adolescents with ≥1 primary ADHD diagnosis who had received ≥30 days of stimulant medication were identified from insurance claims for each calendar year (2011-2014). Use of 15 psychotropic medications concomitantly with stimulants was evaluated and their prevalence in each year was calculated overall and by medication category for children (6-12 years) and adolescents (13-17 years). Results: Each year 133,354 to 157,303 children and 95,632 to 111,280 adolescents were included. Annual period prevalence of any concomitant psychotropic medication use was 22.9% to 25.0% for children and 25.2% to 28.2% for adolescents. The most common medication categories included selective serotonin reuptake inhibitors (children: 6.8%-7.9%; adolescents: 12.7%-14.9%), atypical antipsychotics (4.2%-5.4%; 5.3%-6.3%), and guanfacine extended release (5.1%-7.0%; 2.3%-3.6%). Conclusion: Around a quarter of children/adolescents with ADHD were prescribed psychotropic medication concomitant to stimulant treatment, although only 2 of the 15 medication classes studied were Food and Drug Administration (FDA)-approved for adjunctive use.

Abstract
Objectives: To assess the impact of long-term pharmacotherapy with guanfacine immediate- or extended-release (GXR), administered alone or as an adjunctive to a stimulant, on weight and height in children and adolescents with attention-deficit/hyperactivity disorder (ADHD). Methods: Data were extracted from U.S. Department of Defense medical records for patients 4-17 years of age at index date (initiation of any study medication following a year without ADHD medications, or diagnosis if unmedicated) with weight/height measurements for the analysis period (January 2009-June 2013) and the previous year (baseline). Longitudinal weight and height z-scores were analyzed using multivariable regression in three cohorts: guanfacine (initial period of guanfacine exposure), first-line stimulant monotherapy (initial period of exposure), and unmedicated. Guanfacine cohort subgroups were based on previous/concurrent stimulant exposure. Results: The weight analyses included 47,910 patients (66.8% male) and the height analyses 41,248 (67.2% male). Mean initial exposure in the weight analyses was 237 days (standard deviation [SD] = 258, median = 142) for guanfacine and 257 days (SD = 284, median = 151) for first-line stimulant monotherapy, and was similar in the height analyses. Modeling indicated that guanfacine monotherapy was not associated with clinically meaningful deviations from normal z-score trajectories for weight (first-line, n = 943; nonfirst-line, n = 796) or height (first-line, n = 741; nonfirst-line, n = 644). In patients receiving guanfacine adjunctive to a stimulant, modeled weight (n = 1657) and height (n = 1343) z-scores followed declining trajectories. In this subgroup, mean standardized weight/height had decreased during previous stimulant monotherapy. For first-line stimulant monotherapy, modeled weight (n = 32,999) and height (n = 28,470) z-scores followed declining trajectories during year 1. In the unmedicated cohort, modeled weight (n = 11,515) and height (n = 10,050) z-scores were stable. Conclusions: Guanfacine monotherapy (first-line or nonfirst-line) was not associated with marked deviations from normal growth in this modeling study of children and adolescents with ADHD. In contrast, growth trajectories followed an initially declining course with stimulants, whether given alone or with adjunctive guanfacine.

Abstract
OBJECTIVE Patients with constipation account for 3.1 million US physician visits a year, but care costs for patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) compared to the general public have received little study. The study aim was to describe healthcare utilization and compare medical costs for patients with IBS-C or CIC vs matched controls from a community-based sample. METHODS A nested case-control sample (IBS-C and CIC cases) and matched controls (1:2) for each case group were selected from Olmsted County, MN, individuals responding to a community-based survey of gastrointestinal symptoms (2008) who received healthcare from a participating Rochester Epidemiology Project (REP) provider. Using REP healthcare utilization data, unadjusted and adjusted standardized costs were compared for the 2- and 10-year periods prior to the survey for 115 IBS-C patients and 230 controls and 365 CIC patients and 730 controls. Two time periods were chosen as these conditions are episodic, but long-term. RESULTS Outpatient costs for IBS-C ($6,800) and CIC ($6,284) patients over a 2-year period prior to the survey were significantly higher than controls ($4,242 and $5,254, respectively) after adjusting for co-morbidities, age, and sex. IBS-C outpatient costs ($25,448) and emergency room costs ($6,892) were significantly higher than controls ($21,024 and $3,962, respectively) for the 10-year period prior. Unadjusted data analyses of cases compared to controls demonstrated significantly higher imaging costs for IBS-C cases and procedure costs for CIC cases over the 10-year period. LIMITATIONS Data were collected from a random community sample primarily receiving care from a limited number of providers in that area. CONCLUSIONS Patients with IBS-C and CIC had significantly higher outpatient costs for the 2-year period compared with controls. IBS-C patients also had higher ER costs than the general population.

Abstract
BACKGROUND The prevalence of irritable bowel syndrome with constipation (IBS-C) is estimated to be between 4.3% and 5.2% among adults in the United States. Little is known about the health care resource utilization and costs associated with IBS-C. OBJECTIVES To (a) evaluate the annual total all-cause, gastrointestinal (GI)-related, and IBS-C-related health care costs among IBS-C patients seeking medical care in a commercially insured population and (b) estimate the incremental all-cause health care costs among IBS-C patients relative to matched controls. METHODS Patients aged ≥ 18 years with continuous medical and pharmacy benefit eligibility in 2010 were identified from the HealthCore Integrated Research Database, which consists of administrative claims from 14 geographically dispersed U.S. health plans representing 45 million lives. IBS-C patients were defined as those with ≥ 1 medical claim with an ICD-9-CM diagnosis code in any position for IBS (ICD-9-CM 564.1x) and either ≥ 2 medical claims for constipation (ICD-9-CM 564.0x) on different service dates or ≥ 1 medical claim for constipation plus ≥ 1 pharmacy claim for a constipation-related prescription on different dates of service during the study period. Controls were defined as patients without any medical claims for IBS, constipation, abdominal pain, or bloating or pharmacy claims for constipation-related prescriptions. Controls were randomly selected and matched with IBS-C patients in a 1:1 ratio based on age (± 4 years), gender, health plan region, and health plan type. Patients with diagnoses or prescriptions suggesting mixed IBS, IBS with diarrhea, chronic diarrhea, or drug-induced constipation were excluded. Total health care costs in 2010 U.S. dollars were defined as the sum of health plan and patient paid costs for prescriptions and medical services, including inpatient visits, emergency room (ER) visits, physician office visits, and other outpatient services. The total cost approach was used to assess total all-cause or disease-specific health care costs for patients with IBS-C, while the incremental cost approach was used to examine the excess all-cause costs of IBS-C by comparing IBS-C patients with matched controls. Generalized linear models with bootstrapping were used to assess the incremental all-cause costs attributable solely to IBS-C after adjusting for demographics, Elixhauser Comorbidity Index (ECI) score, and other general and GI-related comorbidities not included in the ECI score. RESULTS A total of 7,652 patients (n = 3,826 each in the IBS-C and control cohorts) were included in the analysis. The mean (± SD) age was 48 (± 17) years, and 83.6% were female. The mean annual all-cause health care costs for IBS-C patients were $11,182, with over half (53.7%) of the costs attributable to outpatient services, including physician office visits and other outpatient services (13.1% and 40.6%, respectively). Remaining total all-cause costs were attributable to hospitalizations (21.8%), prescriptions (19.1%), and ER visits (5.4%). GI-related costs ($4,456) comprised 39.8% of total all-cause costs, while IBS-C-related costs ($1,335) accounted for 11.9% and were primarily driven by costs of other outpatient services (50.3%). After adjusting for demographics and comorbidities, the incremental annual all-cause health care costs associated with IBS-C were $3,856 ($8,621 for IBS-C patients vs. $4,765 for controls, P less than 0.01) per patient per year, of which 78.1% of the incremental costs were due to medical services, and 21.9% were due to prescription fills. CONCLUSIONS IBS-C imposes a substantial economic burden in terms of direct health care costs in a commercially insured population. Compared with matched controls, IBS-C patients incurred significantly higher total annual all-cause health care costs even after controlling for general and GI-related comorbidities. Incremental all-cause costs associated with IBS-C were mainly driven by costs related to more frequent use of medical services as opposed to prescriptions.

Abstract
OBJECTIVE To evaluate total annual all-cause, gastrointestinal-related, and symptom-related healthcare costs among chronic constipation (CC) patients and estimate incremental all-cause healthcare costs of CC patients relative to matched controls. METHODS Patients aged ≥18 years with continuous medical and pharmacy benefit eligibility in 2010 were identified from the HealthCore Integrated Research Database. CC patients had ≥2 medical claims for constipation (ICD-9-CM code 564.0x) ≥90 days apart or ≥1 medical claim for constipation plus ≥1 constipation-related pharmacy claim ≥90 days apart, and no medical claims for irritable bowel syndrome (IBS). Sub-groups with and without abdominal symptoms were classified according to the presence/absence of abdominal pain (ICD-9-CM code 789.0x) and bloating (ICD-9-CM code 787.3x). Controls without claims for constipation, abdominal pain, bloating, or IBS or constipation-related prescriptions were randomly selected and matched 1:1 with CC patients on age, gender, health plan region, and plan type. Generalized linear models with bootstrapping evaluated incremental all-cause costs attributable to CC, adjusting for demographics and comorbidities. RESULTS Overall, 14,854 patients (n = 7427 each in CC and control groups) were identified (mean age = 59 years; 75.4% female). Mean annual all-cause costs for CC patients were $11,991 (2010 USD), with nearly half (44.8%) attributable to outpatient services, including physician office visits and other outpatient services (10.0% and 34.8%, respectively). GI-related costs comprised 33.7% of total all-cause costs. Symptom-related costs accounted for 10.5%, primarily driven by costs of other outpatient services (50.6%). Adjusted incremental all-cause costs associated with CC were $3508 per patient per year ($4446 for CC with abdominal symptoms; $2783 for CC without abdominal symptoms), of which 81.0% were from medical services. Incremental cost estimates may be over- or under-estimated due to classification based on claims. CONCLUSIONS CC imposes a substantial burden in direct healthcare costs in a commercially insured population, mainly attributable to greater use of medical services.

Abstract
Two 6-week studies compared the analgesic efficacy, tolerability and safety of a non-steroidal anti-inflammatory drug (celecoxib 200 mg twice a day [bid]) and an opioid (tramadol HCl 50 mg four times a day [qid]) in subjects with chronic low-back pain (CLBP). Successful responders (primary endpoint) were defined as subjects completing 6 weeks of treatment and having > or = 30% improvement on the Numerical Rating Scale for pain. A total of 796 and 802 subjects were randomized to treatment in study 1 and study 2, respectively. A significantly greater percentage of celecoxib-treated subjects were successful responders compared with tramadol HCl-treated subjects (study 1: 63.2% versus 49.9%, respectively; study 2: 64.1% versus 55.1%, respectively). Fewer adverse events (AEs) and serious AEs were reported in the celecoxib-treated group. Overall, celecoxib 200 mg bid was more effective than tramadol HCl 50 mg qid in the treatment of CLBP, with fewer AEs reported.

Abstract
Selective cyclooxygenase (COX)-2 inhibitors have been associated with an increased risk of thromboembolic cardiovascular (CV) events. Prior studies have found that rofecoxib has a destabilizing effect on blood pressure; however, whether this translates to an increased risk of thromboembolic CV events is unknown. The objective of this study was to evaluate risk of thromboembolic CV events among hypertensive and nonhypertensive patients treated with rofecoxib or celecoxib, nonselective nonsteroidal anti-inflammatory drugs (ns-NSAIDs), or no NSAIDs (nonusers). This was a retrospective cohort study of 31,743 adult arthritis patients enrolled in a Blue Cross/Blue Shield health insurance plan in the northeastern United States. The main outcome measure was incident acute myocardial infarction and stroke. A clinically significant channeling effect was observed where selective COX-2 inhibitor users had a more severe CV risk profile. Among normotensive patients, the hazard ratio (HR) of CV events for ns-NSAIDs, rofecoxib, or celecoxib versus nonusers was 0.91 (95% confidence interval, 0.68-1.21), 1.05 (0.61-1.80), and 1.19 (0.86-1.66), respectively. Among hypertensive patients, the risk of CV events for ns-NSAIDs users was not significantly different versus nonusers (HR=1.21; 0.88-1.67). However, rofecoxib was associated with a significant 2-fold increase in CV risk versus nonusers of NSAIDs (HR=2.16; 1.51-3.09), whereas celecoxib was not (HR=1.18; 0.89-1.57). These data support the hypothesis that elevated CV risk is not a drug class effect of selective COX-2 inhibitors. That this effect was specific to hypertensive patients indicates that blood pressure destabilization is likely an important contributing mechanism.
