CLINICAL NEWS JOURNAL WRAP Kim Eagle, MD, and the editors of ACC.org, present relevant articles taken from various journals. Study Assesses Trends in Readmissions and Use of Observation Units Readmission rates for both targeted and non-targeted conditions are decreasing, and changes in observation-unit stays did not account for the decrease in readmissions. These trends are consistent with hospitals’ response to incentives to reduce readmissions, including financial penalties for readmissions, according to a study published Feb. 24 in the New England Journal of Medicine. Rachael B. Zuckerman, MPH, the Office of the Assistant Secretary for Planning and Evaluation, Department of Health and Human Services, Washington, DC, et al., looked at monthly, hospital-level rates of readmission and observation-service use within 30 days after hospital discharge among Medicare elderly beneficiaries from Oct. 2007, to May 2015 at 3,387 hospitals. Results showed that readmission rates for targeted conditions—acute myocardial infarction, heart failure and pneumonia—declined from 21.5%–17.8%, while rates from nontargeted conditions declined from 15.3%–13.1%. Further, Zuckerman, et al., found that rates began to fall faster in April 2010, after the passage of the Affordable Care Act (ACA), and continued to decline at a slower rate. They also found that the rate of observation-service use for targeted and non-targeted conditions increased throughout the study period, but there was “no significant association” within hospitals between increases in observation service use and reductions in readmission. The authors conclude that the change in rate of readmissions suggests that the Hospital Readmissions Reduction Program, which is included in the ACA, “may have had a broad effect on care, especially for targeted conditions.” The authors add that ACC.org/CSWN moving forward, “given the change in patterns of care during the analysis period, it will be important to continue monitoring these trends.” Zuckerman RB, Steven H.

Studies Examine CVD Care in Women Women may be less likely than men to receive optimal care at hospital discharge when admitted for coronary artery disease (CAD), according to a study published Feb. 23 in a special women’s issue of Circulation: Cardiovascular Quality and Outcomes. The study, led by Deepak L. Bhatt, MD, MPH, looked at 49,358 patients ages 65 and older across 366 U.S. hospitals. Results showed that, compared with men, women were less likely to receive optimal care, and were more likely to have higher mortality if sub-optimal care was received. Further, African-Americans, compared with whites, were also more likely to die from CAD, though this disparity could not be accounted for by differences in the quality of care. The authors ultimately conclude that “approximately 69% of the sex disparity in mortality could potentially be reduced or greatly eliminated by providing optimal and equitable quality of care [to women].” A separate study by Kim Lavoie, PhD, University of Quebec at Montreal, et al., found that anxiety symptoms might mask cardiovascular disease symptoms among women— but not men—and may contribute to referral and diagnostic delays for women. The study looked at 2,342 patients who underwent a SPECT exercise stress test and underwent a psychi- Results showed that, compared with men, women [...] were more likely to have higher mortality if sub-optimal care was received. atric interview to assess mood and anxiety disorders. Results showed that in those without a history of CAD, women with anxiety were more likely to exhibit ischemia during exercise compared to women without anxiety. No significant effects were observed for men. The authors conclude that, moving forward, additional research is needed to confirm these findings, and that “future work should also investigate the extent to which psychiatric disorders affect care trajectory and/ or CAD outcomes among men and women, and whether interventions to improve psychiatric status among those with or at risk for CAD could improve outcomes.” Li S, Fonarow GC, Mukamal KJ, et al.
