Outcomes of Transcatheter Aortic Valve Implantation in Nonagenarians Compared to <90 Years Patients.
Given that life expectancy has improved, nonagenarians have become a significant proportion of world population. As aortic stenosis is primarily a disease of the elderly, the need for invasive cardiac approaches is expected to increase in people of extreme age. Herein, we compare the in-hospital adverse clinical outcomes and mortality after transcatheter aortic valve implantation (TAVI) procedures in nonagenarians to younger than 90 year old patients. ⋯ The prevalence of TAVI procedural success is remarkably high in nonagenarians and comparable to that of younger patients. However, the in-hospital mortality rate was 2-fold more than that of <90-year-old patients.

Unnecessary laboratory tests contribute to iatrogenic harm and are a major source of waste in the health care system. We previously developed a machine learning algorithm to help clinicians identify unnecessary laboratory tests, but it has not been externally validated. In this study, we externally validate our machine learning algorithm. ⋯ We externally validated the machine learning model and showed that the model performed similarly, supporting the generalizability to other settings. While this model demonstrated good performance for predicting abnormal labs and transitions, it does not perform well enough for prediction of laboratory values in most clinical applications.

The purpose of this research was to use direct observation of the physical examination to elucidate the role physical examination technique plays in diagnostic accuracy. Physical examination is important for quality clinical care and requires multiple interrelated skills. The relationship of physical examination technique to related skills is poorly understood. Current methods of teaching and assessing physical examination skills provide few opportunities to evaluate physical examination technique and accuracy. ⋯ Our findings emphasize the necessity of multi-dimensional physical examination assessment. Observed deterioration of physical examination skill during internship may reflect contemporary practice patterns, which deprioritize the physical examination. Future research on physical examination education should focus on the interface between physical examination technique and related clinical skills.

The Braden Skin Score (BSS) is a bedside nursing assessment that may be a measure of frailty and predicts mortality among patients in the cardiac intensive care unit (CICU). We examined the association between each of the 6 individual BSS subscores with hospital mortality in patients in the CICU. We hypothesized that BSS subscores reflecting patient frailty would have a stronger association with outcomes. ⋯ BSS can serve as a rapid noninvasive screening tool for identifying poor outcomes in patients in the CICU. BSS subdomains that are more strongly associated with mortality appear to reflect physical frailty. Insofar as the BSS and its subscores measure frailty, a low BSS may identify frail patients.

Residents serve as access points to the health care system for the most vulnerable patients in the United States. Two large academic medical centers have identified performance gaps between resident and faculty physicians. Our intent in this study was to measure the scope of resident-faculty performance gaps in a nationwide sample and identify potential targets for intervention. ⋯ Resident-faculty performance disparities may be a widespread problem nationally. Potential targets for intervention include increased preceptor engagement, improving access for empanelment in the faculty practice for vulnerable patient populations, and employing more robust handoff practices. Integrating a culture of quality improvement to continuously monitor important educational metrics such as outcome disparities, panel demographics, educational continuity, and patient loss in the resident panel should be a routine practice for academic health centers.
