Preoperative Management of Gastrointestinal and Pulmonary Medications: Society for Perioperative Assessment and Quality Improvement (SPAQI) Consensus Statement.

Perioperative medication management is integral to preoperative optimization but remains challenging because of a paucity of literature guidance. Published recommendations are based on the expert opinion of a small number of authors without collaboration from multiple specialties. The Society for Perioperative Assessment and Quality Improvement (SPAQI) recognized the need for consensus recommendations in this area as well as the unique opportunity for its multidisciplinary membership to fill this void. In a series of articles within this journal, SPAQI provides preoperative medication management guidance based on available literature and expert multidisciplinary consensus. The aim of this consensus statement is to provide practical guidance on the preoperative management of gastrointestinal and pulmonary medications. A panel of experts with anesthesiology, perioperative medicine, hospital medicine, general internal medicine, and medical specialty experience was drawn together and identified the common medications in each of these categories. The authors then used a modified Delphi approach to review the literature and to generate consensus recommendations.

Use of adenosine triphosphate to audit reprocessing of flexible endoscopes with an elevator mechanism.

BACKGROUND: There have been reported outbreaks of carbapenem-resistant Enterobacteriaceae infections linked to endoscopes with elevator mechanisms. Adenosine triphosphate (ATP) testing has been used as a marker for bioburden and monitoring manual cleaning for flexible endoscopes with and without an elevator mechanism. The objective of this study was to determine whether routine ATP testing could identify areas of improvement in cleaning of endoscopes with an elevator mechanism. METHODS: ATP testing after manual cleaning of TJF-Q180V duodenoscopes and GF-UCT180 linear echoendoscopes (Olympus America Inc, Center Valley, PA) was implemented. Samples were tested from the distal end, the elevator mechanism, and water flushed through the lumen of the biopsy channel. Data were recorded and compared by time point, test point, and reprocessing technician. RESULTS: Overall failure rate was 6.99% (295 out of 4,219). The highest percentage of failed ATP tests (17.05%) was reported in the first quarter of routine testing, with an overall decrease in rates over time. The elevator mechanism and working channel lumen had higher failure rates than the distal end. Quality of manual cleaning between reprocessing technicians showed variation. CONCLUSION: ATP testing is effective in identifying residual organic material and improving quality of manual cleaning of endoscopes with an elevator mechanism. Cleaning efficacy is influenced by reprocessing technicians and location tested on the endoscope. Close attention to the working channel and elevator mechanism during manual cleaning is warranted.

Dyssynergic defecation: a treatable cause of persistent symptoms when inflammatory bowel disease is in remission.

BACKGROUND: Introduction of biologic agents in inflammatory bowel disease (IBD) has increased the likelihood of disease remission. Despite resolution of active inflammation, a subset of IBD patients report persistent defecatory symptoms. AIM: To evaluate a group of patients with inflammatory bowel disease with suspected functional defecatory disorders, by use of anorectal manometric testing and subsequent biofeedback therapy. METHODS: A group of IBD patients with persistent defecatory problems despite clinical improvement were included in this study. These patients had no evidence of left-sided disease. Endoscopic and radiographic study findings and timing in relation to the manometry study were recorded. Anorectal manometry was performed by the standard protocol and included rectal sensory assessment, ability to expel a balloon, and pressure dynamics with simulated defecation. RESULTS: Thirty IBD patients (Crohn's 23 patients; ulcerative colitis six patients) presented with defecatory disorders including constipation (67%) increased stooling (10%), and rectal urgency and/or incontinence and rectal pain (6%). All but one patient had anorectal manometric criteria of dyssynergia (presence of anismus motor pattern and inability to expel the balloon). Of the patients who completed biofeedback therapy, 30% had a clinically significant (≥7-point) improvement in SIBDQ score, with a reduction in health-care utilization after a six-month period (p=0.02). CONCLUSIONS: Despite remission, some inflammatory bowel disease patients have persistent defecatory symptoms. Defecatory symptoms may not be predictive of an underlying inflammatory disorder. Lack of inflammatory activity and absence of left-sided disease should prompt investigation of functional disorders. Anorectal manometric testing and biofeedback therapy for patients with a diagnosis of dyssynergia may be a useful therapy.

Surgical outcomes in the elderly with inflammatory bowel disease are similar to those in the younger population.

BACKGROUND: Inflammatory bowel disease (IBD) has a bimodal distribution with approximately 15 % of patients manifesting after age 65. Previous reports suggest an increased risk of surgical complications in the elderly. AIM: To compare surgical outcomes in elderly IBD patients (≥ 65 years at the time of surgery) to matched younger IBD cohorts. METHODS: This was a retrospective cohort study at a single academic center of patients who underwent surgery for IBD. Forty-two elderly patients (≥ 65 years) were matched at least 1:1 (median 1:5) to patients in each of three control groups [18-35 years (n = 71); 36-49 years (n = 62); 50-64 years (n = 58)] according to gender, disease type/location, and type of surgery. Postoperative complications were compared. Patient characteristics were used in multivariate risk models. Analysis was performed using ordinary logistic regression. RESULTS: Twenty ileal or ileocolonic resections, 12 partial or total colectomies, four stricturoplasties, and six laparoscopic partial or total colectomies were performed in the elderly group. The post-operative complication rate was not statistically different between the elderly and younger cohorts (38 % vs. 39 % vs. 40 % vs. 48 % in the 18-35, 36-49, 50-64, and ≥ 65 years groups, respectively, p = 0.26). The only significant risk factors for complication were Charlson comorbidity index (p = 0.0002), preoperative hemoglobin (p = 0.0065), total parenteral nutrition use (p = 0.024), and failed medical therapy (as the indication for surgery) (p = <0.0001). CONCLUSIONS: The surgical complication rate among elderly and younger IBD patients was similar. Advanced age by itself should not be considered a risk factor for adverse operative outcome.

Impact of pregnancy on health-related quality of life of patients with inflammatory bowel disease.

OBJECTIVE: To examine the impact of pregnancy on health-related quality of life (HRQoL) of women with inflammatory bowel disease (IBD). METHODS: This was a retrospective study in a tertiary referral center and included women with ≥2 short inflammatory bowel disease questionnaire (SIBDQ) scores obtained during their pregnancy. Regression models were used to identify independent factors influencing SIBDQ scores and changes of SIBDQ scores at different time points. RESULTS: A total of 32 women (23 CD, 9 UC) with a mean age at pregnancy of 29.4 years and a mean disease duration of 7.8 years were included in the study. The mean pre-pregnancy SIBDQ score in our cohort was 49, which was significantly lower than the values during (55, P < 0.001) and post-pregnancy (53, P = 0.01). The score during pregnancy directly correlated with the pre-pregnancy SIBDQ score (correlation co-efficient 0.50, P = 0.003). Half of the patients had a ≥7-point increase in SIBDQ scores during pregnancy. Change in SIBDQ scores during pregnancy was inversely related to the pre-pregnancy score (-0.47, 95% CI -0.75 to -0.20) and changes in disease activity during pregnancy (-1.80, 95% CI -0.75 to -0.20). CONCLUSIONS: Half of the pregnant women with IBD in our cohort experienced improvement in their HRQoL. Pre-pregnancy HRQoL is predictive of HRQoL during pregnancy, supporting the need for optimizing disease activity prior to conception.

Vitamin D deficiency in patients with inflammatory bowel disease: association with disease activity and quality of life.

BACKGROUND: Vitamin D deficiency is common in inflammatory bowel disease (IBD). The aim of the study was to determine the prevalence and predictors of vitamin D deficiency in an IBD cohort. It was hypothesized that vitamin D deficiency is associated with increased disease activity and lower health-related quality of life (HRQOL). METHODS: This was a retrospective cohort study. Harvey-Bradshaw index and ulcerative colitis disease activity index were used to assess disease activity. Short Inflammatory Bowel Disease Questionnaire scores were used to assess HRQOL. Multivariate logistic regression was used to identify independent predictors of vitamin D deficiency and its association with disease activity and HRQOL. RESULTS: The study included 504 IBD patients (403 Crohn's disease [CD] and 101 ulcerative colitis [UC]) who had a mean disease duration of 15.5 years in CD patients and 10.9 years in UC patients; 49.8% were vitamin D deficient, with 10.9% having severe deficiency. Vitamin D deficiency was associated with older age (P = .004) and older age at diagnosis (P = .03). Vitamin D deficiency was associated with lower HRQOL (regression coefficient -2.21, 95% confidence interval [CI], -4.10 to -0.33) in CD but not UC (regression coefficient 0.41, 95% CI, -2.91 to 3.73). Vitamin D deficiency was also associated with increased disease activity in CD (regression coefficient 1.07, 95% CI, 0.43 to 1.71). CONCLUSIONS: Vitamin D deficiency is common in IBD and is independently associated with lower HRQOL and greater disease activity in CD. There is a need for prospective studies to assess this correlation and examine the impact of vitamin D supplementation on disease course.

QuantiFERON TB gold testing for tuberculosis screening in an inflammatory bowel disease cohort in the United States.

BACKGROUND: Reactivation of latent Mycobacterium tuberculosis (TB) is a rare, yet devastating infectious complication associated with anti-tumor necrosis factor alpha (TNF-α) therapy. We evaluated the performance of the QuantiFERON TB Gold test (QFT-G) for TB screening in a cohort of inflammatory bowel disease (IBD) patients in the United States. METHODS: We performed a retrospective, observational study of patients initiated and/or maintained on an anti-TNF-α agent in a single IBD referral center and recorded the frequency and the test results of QFT-G testing and the rate of TB reactivation. RESULTS: 512 QFT-G tests were done in 340 patients. Five patients (1.5%) had a positive, nine (2.7%) indeterminate, and 326 patients (95.8%) had a negative QFT-G. After a mean follow-up of 17 months there was one case of TB reactivation (0.3%). The use of immunosuppressive therapy or anti-TNF therapy at the time of testing did not affect the results of the QFT-G testing. Test-retest had substantial concordance (κ = 0.72). 25% of patients (n = 85) had TST testing. Concordance between the TST and QFT-G was found to be moderate (κ = 0.4152, P = 0.0041). CONCLUSIONS: Most patients with negative QFT-G tolerated anti-TNF therapy with no evidence of TB reactivation. Concomitant use of immunosuppressive therapy or anti-TNF did not seem to affect QFT-G results. One patient had an indeterminate QFT-G while on infliximab and later developed miliary TB. Concordance with TST is moderate.

Does primary sclerosing cholangitis impact quality of life in patients with inflammatory bowel disease?

BACKGROUND: Impairment of health-related quality of life (HRQoL) is an important concern in inflammatory bowel disease (IBD; ulcerative colitis [UC], Crohn's disease [CD]). Between 2%-10% of patients with IBD have primary sclerosing cholangitis (PSC). There has been limited examination of the disease-specific HRQoL in this population compared to non-PSC IBD controls. METHODS: This was a retrospective, case-control study performed at a tertiary referral center. Cases comprised 26 patients with a known diagnosis of PSC and IBD (17 UC, 9 CD). Three random controls were selected for each case after matching for IBD type, gender, age, and duration of disease. Disease-specific HRQoL was measured using the Short Inflammatory Bowel Disease Questionnaire (SIBDQ). Disease activity for CD was measured using the Harvey-Bradshaw index (HB) and using the UC activity index for UC. Independent predictors of HRQoL were identified. RESULTS: There was no significant difference in the age, gender distribution, or disease duration between PSC-IBD and controls. There was no difference in use of immunomodulators or biologics between the 2 groups. Mean SIBDQ score was comparable between PSC-IBD patients (54.5) and controls (54.1), both for UC and CD. Likewise, the disease activity scores were also similar (2.8 versus 3.1, P = 0.35). On multivariate analysis, higher disease activity score (-1.33, 95% confidence interval [CI] 95% CI -1.85 to -0.82) and shorter disease duration were predictive of lower HRQoL. Coexisting PSC did not influence IBD-related HRQoL. There was a higher proportion of permanent work disability in PSC-IBD (7.7%) compared to controls (0%). CONCLUSIONS: PSC does not seem to influence disease-specific HRQoL in our patients with IBD but is associated with a higher rate of work disability.
