Acceptance and Commitment Therapy Reduces Psychological Stress in Patients With Inflammatory Bowel Diseases.

BACKGROUND & AIMS: Patients with Crohn's disease or ulcerative colitis have relatively high levels of stress and psychological dysfunction. Acceptance and commitment therapy (ACT) is a psychological intervention that comprises acceptance and mindfulness procedures, along with commitment and behavior change strategies, to increase psychological flexibility and reduce stress. We performed a randomized controlled trial to investigate the effect of ACT on stress in patients with inflammatory bowel diseases (IBD). METHODS: A total of 122 patients with quiescent or stable, mildly active IBD were randomly assigned to an 8-week ACT program or treatment as usual (control group). Clinical, demographic, disease activity, and psychological data and blood and feces were collected at baseline and at 8 weeks and 3 months after the intervention (week 20). Scalp hair was collected at baseline and week 20 for measurement of steroid concentrations. The primary endpoint was change in stress symptoms, assessed with the Depression Anxiety Stress Scale. Secondary endpoints included changes in perceived stress, anxiety, depression, quality-of-life domains, disease activity, and cortisol concentration in hair. RESULTS: Overall, 79 participants were included in the complete case intention-to-treat analysis. There were 39% and 45% reductions in stress in the treatment group from baseline to 8 and 20 weeks, respectively, compared with 8% and 11% in the control group (group × time interaction, P = .001). ACT was associated with reduced perceived stress (P = .036) and depression (P = .010), but not anxiety (P = .388), compared with control individuals. In the intention-to-treat analysis, changes in all 4 quality-of-life domains over time were similar in the ACT and control groups. In the per-protocol analysis, the overall well-being quality-of-life domain improved in the ACT group compared with the control group (P = .009). Subjective and objective disease activity measurements were similar between groups over the study period (all P values >.05). Hair cortisol concentrations correlated with stress (rs = 0.205, P = .050) and anxiety (rs = 0.208, P = .046) at baseline but did not change significantly in the ACT group over the study period compared with the control group (P = .831). CONCLUSION: In a randomized controlled trial of patients with IBD, an 8-week ACT therapy course improved stress and other indices of psychological health.ClinicalTrials.gov Identifier: NCT02350920.

Assessment of the value of gastroenterologists' activity in the outpatient setting: applying the "Moneyball" approach to clinical care.

BACKGROUND: With the emergence of alternative payment systems replacing the traditional funding models, the value of physician activity is scrutinized more closely. Attempts have been made to quantify the value of endoscopists' activity; there is little in the medical literature describing gastroenterologists' value in the outpatient setting. AIMS: To characterize the value of clinical activity of gastroenterologists in the outpatient setting. METHODS: The value of clinical activity of ten gastroenterologists in an academic medical center was estimated. Value was defined as Q (quality of clinical care) divided by TA (duration of outpatient visit adjusted for complexity level); TA served as a surrogate measure of the cost of the clinician's services. Medical records of each patient's clinical visit were reviewed and graded independently by three staff gastroenterologists; each reviewer was blinded to the identity of the physician and to other reviewers' scores. RESULTS: Over consecutive weeks, the clinical records of 307 patients who were seen by ten gastroenterologists were reviewed and graded for quality (Q) and complexity (C); the duration of each visit (T) was recorded. Each physician saw a mean of 31 patients; mean physician value varied from 0.28 to 0.87. More senior physicians demonstrated higher levels of value. CONCLUSION: Measurement of the value of clinical activity represents an important component of gastroenterologists' performance. There was a threefold variation among physician levels of value with more experienced clinicians demonstrating higher value levels. Further studies will be required to more clearly define valid metrics for physician value.

CRP/Albumin Ratio: An Early Predictor of Steroid Responsiveness in Acute Severe Ulcerative Colitis.

INTRODUCTION: Identifying hospitalized patients with acute severe ulcerative colitis (ASUC) who will be refractory to corticosteroid therapy and require rescue therapy remains difficult. Hypoalbuminemia worsens with time during hospitalization and is associated with rapid clearance of and reduced response to infliximab (IFX) rescue. Early use of rescue therapy may therefore be more effective. Simple clinical and laboratory predictors of corticosteroid responsiveness would facilitate earlier use of rescue therapy. MATERIALS AND METHODS: Retrospective study of a prospectively maintained database of 3600 patients attending a single center was conducted. Patients with histologically confirmed ulcerative colitis admitted with ASUC over a 5-year period from January 2010 to December 2014 were identified. All patients initially received intravenous corticosteroids. Patient demographics were collected; C-reactive protein (CRP) and albumin levels were recorded at baseline and during admission. Receiver operating characteristic statistics were used to determine the optimal stool frequency, CRP, albumin, and CRP/albumin ratio (CAR) to predict steroid response. RESULTS: A total of 124 ASUC patients were admitted during a 5-year period. Median follow-up was 2.3 years. A total of 62 patients (50%) were steroid responsive, 55 patients (44%) received rescue IFX, 22 patients (18%) required colectomy within 30 days of admission, whereas a further 14 (11%) required colectomy during follow-up. By receiver operating characteristic statistics, day 3 CAR was a more accurate marker of steroid responsiveness than day 3 CRP or day 3 albumin alone [area under curve=0.75 (P<0.001)]. The optimal CAR to predict response to steroids on day 3 was 0.85 (sensitivity 70%, specificity 76%). When combined with D3 stool frequency, specificity improved to 83%. If at day 3, CAR was >0.85 and stool frequency was >3, the relative risk of steroid nonresponse was significantly raised at 3.9 (95% confidence interval, 2.1-7.2). CONCLUSIONS: Raised D3 CAR is an early predictor of steroid-refractory ASUC. When combined with D3 stool frequency, its predictive ability improves. In patients with predicted steroid nonresponse, early introduction of rescue IFX at this stage may be more effective, before serum albumin falls profoundly.

Covered self-expanding metal stents for the management of common bile duct stones.

BACKGROUND AND AIMS: Little medical literature exists for the use of fully covered self-expanding metal stents (CSEMSs) in the management of retained common bile duct (CBD) stones. Our aim was to assess the safety and efficacy of CSEMSs for the indication of retained "difficult" CBD stones. METHODS: This retrospective cases series included 44 patients (30 women; median age, 69 years [range, 24-88]) who underwent CSEMS insertion for the indication of retained "difficult" CBD stones in 2 tertiary referral centers. Patients underwent temporary placement of CSEMSs after incomplete stone clearance at ERCP. Follow-up ERCP was arranged for stent removal and subsequent attempt at duct clearance. Procedure-related adverse events were also recorded. RESULTS: Successful biliary drainage was achieved in all cases after CSEMS placement. Forty-two stents were removed with successful duct clearance achieved in 36 cases (82%) after a median in-stent duration of 8 weeks. There were 10 cases (22.7%) of stent migration, all noted incidentally during follow-up. One patient died of nonbiliary causes before attempted removal. CONCLUSION: This is the largest published retrospective case series for use of CSEMSs for management of retained CBD stone disease to date. We have shown high success rates for this indication. A well-designed, multicenter, randomized controlled trial might address the uncertainty of cost-to-benefit ratio and appropriate duration for CSEMSs to be left in situ. Specific stent modification for this indication, including wider distal flare and retrieval purse string loop, may also be useful.
