What your patient reads: creating a value-added tool for physicians.

Through a number of media sources, today's consumers have unprecedented access to health information of varying reliability and authority. Empowered by this information, patients are more involved in their health care decisions and more willing to question physicians' advice. This poses a challenge for physicians who must now find time to read mass media health reports in addition to medical research. In order to help physicians with this task, librarians at the University of Manitoba Health Sciences Libraries created What Your Patient Reads - one-page summaries of health-related media reports supplemented with references to evidence-based medical literature.

The impact of frailty on outcomes after cardiac surgery: a systematic review.

OBJECTIVE: Current preoperative assessments for cardiac surgery, such as the European System for Cardiac Operative Risk Evaluation II and the Society of Thoracic Surgeons risk score, are limited in their ability to predict postoperative outcomes. This is thought to be due to the reliance on chronological age as a predictor of health. In geriatrics, frailty assessments have been developed as a tool in determining physiologic functioning capacity. Whether or not frailty predicts postoperative outcomes independent of existing cardiac preoperative risk scores remains unknown. METHODS: We performed a systematic review to determine the association of frailty with negative postoperative outcomes such as major adverse cardiac and cerebrovascular events (MACCE) in patients undergoing cardiac surgery. We searched PubMed, EMBASE, the Cochrane library, and Ageline from inception until July 2013 and screened 5913 abstracts for potential inclusion. Of these, 6 studies examined the relationship between objective frailty assessments and postoperative outcomes. Our included studies evaluated 4756 patients undergoing cardiac surgery. RESULTS: Frailty, defined using multiple criteria, had a strong positive relationship with the risk of MACCE (odds ratio, 4.89; 95% confidence interval, 1.64-14.60). Relationships were stronger in older patients undergoing transcatheter aortic valve replacement (TAVR) than younger patients undergoing coronary artery bypass grafting and valvular surgery (hazard ratio for frailty in TAVR, 3.31-4.89 vs hazard ratio for non-TAVR, 1.10-3.16). CONCLUSIONS: Patients deemed frail, determined using an objective assessment tool, have a higher likelihood of experiencing mortality, morbidity, functional decline, and MACCE following cardiac surgery, regardless of definition. Further study is needed to determine which components of frailty are most predictive of negative postoperative outcomes before integration in risk prediction scores.
