Abstract Background and study aims Endoscopic biliary intervention (BI) is often difficult to perform in patients with prior bariatric surgery (BRS). We sought to analyze outcomes of patients with prior BRS undergoing endoscopic and non-endoscopic BI. Patients and methods The Nationwide Inpatient Sample (2007 – 2011) was reviewed to identify all adult inpatients (≥ 18 years) with a history of BRS undergoing BI. The clinical outcomes of interest were in-patient mortality, length of stay (LOS), and total hospital charges. Results There were 7,343 patients with prior BRS who underwent BIs where a majority were endoscopic (4,482 vs. 2,861, P < 0.01). The mean age was 50±30.8 years and the majority were females (80.5 %). Gallstone-related disease was the most common indication for BI and managed more often with primary endoscopic management (2,146 vs. 1,132, P < 0.01). Inpatient mortality was not significantly different between patients undergoing primary endoscopic versus non-endoscopic BI (0.2 % vs. 0.7 %, P = 0.2). Patients with sepsis were significantly more likely to incur failed primary endoscopic BI (OR 2.74, 95 % CI 1.15, 6.53) and were more likely to be managed with non-endoscopic BI (OR 2.13, 95 % CI 1.3, 3.5). Primary non-endoscopic BI and failed endoscopic BI were both associated with longer LOS (by 1.77 days, P < 0.01 and by 2.17 days, P < 0.01, respectively) and higher hospitals charges (by $11,400, P < 0.01 and by $ 14,200, P < 0.01, respectively). Conclusion Primary endoscopic management may be a safe and cost-effective approach for patients with prior BRS who need BI. While primary endoscopic biliary intervention is more common, primary non-endoscopic intervention may be used more often for sepsis.

Background: Prior studies have not examined national trends and characteristics of unintentional non–health care facility (HCF) medication errors associated with cardiovascular drugs. Objective: To investigate non-HCF medication errors associated with cardiovascular drugs reported to poison control centers in the United States. Methods: A retrospective analysis of non-HCF medication errors associated with cardiovascular drugs from 2000 to 2012 was conducted using the National Poison Data System database. Results: There were 278 444 medication errors associated with cardiovascular drugs reported to US poison control centers during the study period, averaging 21 419 exposures annually. The overall rate of cardiovascular medication errors per 100 000 population increased 104.6% from 2000 to 2012 ( P < 0.001) and the highest rates were among older adults. Most cases (83.6%) did not require treatment at a HCF. Serious medical outcomes were reported in 4.0% of exposures. The cardiovascular drugs most commonly implicated in medication errors were β-blockers (28.2%), calcium antagonists (17.7%), and angiotensin-converting enzyme inhibitors (15.9%). Most of the 114 deaths were associated with cardiac glycosides (47.4%) or calcium antagonists (29.8%). Most medication errors involved taking or being given a medication twice (52.6%). Conclusions: This study describes characteristics and trends of non-HCF cardiovascular medication errors over a 13-year period in the United States. The number and rate of cardiovascular medication errors increased steadily from 2000 to 2012, with the highest error rates among older adults. Further research is needed to identify prevention strategies for these errors, with a particular focus on the older adult population.

SummaryBackgroundMicroscopic colitis (MC) is a common cause of chronic diarrhoea. Various treatment options have been described, but there are limited data describing outcomes of corticosteroid‐sparing treatments.AimTo evaluate the outcomes of patients with active MC treated with immune modulators.MethodsAll patients seen at Mayo Clinic, Rochester between January 1, 1997 and November 30, 2016 with a histological diagnosis of MC were identified. Patients treated with an immune modulator of interest were selected and clinical outcomes recorded.ResultsSeventy‐three MC patients (50 collagenous colitis and 23 lymphocytic colitis) with a median disease duration of 24 months (range, 7‐60) were included. The indications for treatment were budesonide‐refractoriness in 66%, budesonide dependence in 29%, and budesonide intolerance in 5%. Median age was 51.8 years (range, 43.4‐63.1) and 61 (84%) were female. Thiopurines were used in 49 patients (67%) for a median of 4 months (range, 1.5‐15). Complete and partial response occurred in 43% and 22% respectively. Adverse effects resulting in therapy cessation occurred in 17 patients (35%). Twelve patients (16%) were treated with methotrexate for a median of 14 months (3‐18.8). Complete and partial response occurred in 58% and 17%, respectively. Anti‐TNF therapy was used in 10 patients (14%) for a median of 4 months (range, 2.3‐5.5). Complete response occurred in four patients and partial response in four patients.ConclusionsThe majority of patients with active MC responded to thiopurines, methotrexate, or anti‐TNF therapy. Larger controlled studies are required to confirm the efficacy and safety of these medications in MC.
