[EX Q]: Intravenous tissue-type plasminogen activator (tPA) is a proven treatment for acute ischemic stroke, but there has been limited evaluation among patients aged ≥90 years.', 'We analyzed data from the Get With The Guidelines-Stroke national quality improvement registry from January 2009 to April 2013. Frequency, determinants, and outcomes of tPA use were compared among patients aged ≥90 and 3 younger age groups (18-64, 65-79, and 80-89 years).', 'Among 35\u2009708 patients from 1178 sites who arrived within 2 hours of time last known well and received tPA, 2585 (7.2%) were ≥90 years. Compared with younger patients, the rate of tPA use among patients without a documented contraindication was lower among patients aged ≥90 years (67.4% versus 84.1% in 18-89-year olds; P<0.0001). Discharge outcomes among individuals aged ≥90 years included discharge to home or acute rehabilitation in 31.4%, independent ambulation at discharge in 13.4%, symptomatic hemorrhage in 6.1%, and in-hospital mortality or hospice discharge in 36.4%. On multivariable analysis, good functional outcomes generally occurred less often and mortality more often among patients aged ≥90 years. The risk of symptomatic hemorrhage was increased compared with patients <65 years but was not significantly different than the risk in 66- to 89-year olds.

[EX Q]: To determine whether a paper-based antibiotic ordering system is an effective antibiotic stewardship measure.', 'An antibiotic order form (AOF) was introduced in July 2001 at a pediatric tertiary care hospital. Vancomycin courses prescribed before and after the AOF introduction were retrospectively reviewed based on Hospital Infection Control Practices Advisory Committee guidelines. The impact of the AOF on the appropriateness of vancomycin prescribing was evaluated in univariate and multivariable analyses that adjusted for other factors associated with appropriateness of vancomycin use. The density of vancomycin use after introduction of the AOF was also assessed.', 'Compliance with the AOF was poor (<50%) during the planned study period; therefore an additional 2 months of improved compliance (70-80%) were included. Rates of inappropriate vancomycin use increased during the study periods: 35% before AOF; 39% post-AOF; and 51% during the improved compliance period. On adjusted analysis, vancomycin utilization was significantly more inappropriate after introduction of the AOF. Vancomycin doses per 1000 patient days increased after introduction of the AOF.

[EX Q]: The cause of rheumatoid arthritis (RA) flares is multifactorial and not well understood. No reports of fractures influencing disease activity in patients with RA have been published. The purpose of this study was to determine whether fractures influence disease activity in patients with RA.', 'Hospital records of 470 patients with RA between 2011 and 2014 were analyzed. We first examined the incidence of flare using multiple regression analysis. Secondly, we examined the incidence of flare using DAS28-ESR, DAS28-CRP, and drug changes before bone fracture until bone union in the fracture cases.', 'Multiple linear regression analysis showed that female sex (p\u2009<\u20090.001), bottom DAS28-ESR (p\u2009<\u20090.001), and fracture (p\u2009=\u20090.041) were independent factor for DAS28-ESR at the last observation period, and sex (p\u2009=\u20090.040), bottom DAS28-CRP (p\u2009<\u20090.001), and fracture (p\u2009=\u20090.019) were independent factor for DAS28-CRP at the last observation period. The average DAS28-ESR value was significantly increased from 3.19 (prefracture) to 3.58 (bone union). The average DAS28-CRP value was also significantly increased from 2.45 (prefracture) to 2.79 (bone union).
