RESUMO
OBJECTIVES: We sought to characterize how the perceived risk of early dual antiplatelet therapy (DAPT) discontinuation is incorporated into operator decision-making regarding stent choice, using a simple pre-procedure survey screening for clinical variables that may lead to early DAPT discontinuation. BACKGROUND: Understanding which factors influence operator decision-making regarding stent choice during percutaneous coronary intervention (PCI) could help identify areas for quality improvement. METHODS: We retrospectively identified 1202 patients who underwent PCI from July 2008 to January 2013 at the Durham Veterans Affairs Medical Center. We excluded patients without a complete pre-procedure survey within 14days of PCI, repeat procedures on the same patient and those who received both drug-eluting stents (DES) and bare-metal stents (BMS) or no stent during PCI, leaving 864 patients. The primary outcome was the independent association of "yes" responses to survey items with the odds of DES use during PCI. RESULTS: Of 864 patients, 661 received DES and 203 received BMS. A "yes" response to "planned major surgery or dental work in the next year" (OR 0.20, 95% CI 0.11-0.36, p<0.001), "recent bleeding event or bleeding diathesis" (OR 0.31, 95% CI 0.14-0.68, p=0.003) or "currently taking Coumadin" (OR 0.39, 95% CI 0.19-0.78, p=0.007) was independently associated with lower odds of DES use. CONCLUSIONS: Responses to 3 items on a simple pre-procedure survey screening for clinical variables that may lead to early DAPT discontinuation were independently associated with stent type used during PCI, suggesting the importance of these factors in an operator's stent choice.

BACKGROUND: Patients with primary sclerosing cholangitis (PSC) and colonic inflammatory bowel disease (IBD) demonstrate increased risk of colorectal cancer. Prior studies have yielded conflicting information on the relationship between ursodiol (UDCA) and the risk of colorectal cancer or dysplasia in this group. AIMS: To examine the impact of UDCA on risk of colorectal cancer or dysplasia in adult PSC and IBD patients. METHODS: A systematic review and meta-analysis of case-control and cohort studies was performed. Subgroup analysis compared the effects of "low-to-medium" (<25 mg/kg/day) versus "high" dose (≥ 25 mg/kg/day) UDCA exposures. RESULTS: Inclusion and exclusion criteria, as well as all variables, were determined a priori. Seven papers, with 707 participants and greater than 5,751 person-years of follow-up time, met the criteria for final analysis. The overall pooled relative risk using a random effects model was not statistically significant (RR = 0.87, 95 % CI 0.51-1.49, p = 0.62). Subgroup analysis by UDCA dose category in a random effects model was not statistically significant (RR = 0.64, 95 % CI 0.38-1.07, p = 0.09), but suggested a possible trend in risk reduction at low-to-medium-dose exposures that may warrant further investigation. CONCLUSION: UDCA use was not associated with risk of colorectal cancer or dysplasia in adult PSC and IBD patients, but UDCA dose was a source of heterogeneity across studies. Subgroup analysis suggests a possible trend toward decreased colorectal cancer risk in low-to-medium-dose exposures. Additional study of UDCA treatments at low doses in PSC and IBD patients may be warranted.
