Dyspnea is a common and often debilitating symptom with a complex diagnostic work-up.

Technologic advancements and the evolving digital health landscape have offered innovative solutions to several of our health care system's issues as well as increased the number of digital interactions and type of personal health information that is generated and collected, both within and outside of traditional health care. This American College of Physicians' position paper discusses the state of privacy legislation and regulations, highlights existing gaps in health information privacy protections, and outlines policy principles and recommendations for the development of health information privacy and security protections that are comprehensive, transparent, understandable, adaptable, and enforceable. The principles and recommendations aim to improve on the privacy framework in which physicians have practiced for decades and expand similar privacy guardrails to entities not currently governed by privacy laws and regulations. The expanded privacy framework should protect personal health information from unauthorized, discriminatory, deceptive, or harmful uses and align with the principles of medical ethics, respect individual rights, and support the culture of trust necessary to maintain and improve care delivery.

The American College of Physicians (ACP) developed this guideline to provide clinical recommendations on the appropriate use of high-flow nasal oxygen (HFNO) in hospitalized patients for initial or postextubation management of acute respiratory failure. It is based on the best available evidence on the benefits and harms of HFNO, taken in the context of costs and patient values and preferences.

In their article, McKay and colleagues show that rapid antigen tests have utility in nursing home settings to screen nursing home residents and staff. The editorialists discuss how these findings provide additional support to the idea that antigen testing could be useful to identify people who are likely to be contagious and may transmit SARS-CoV-2, and that rapid antigen tests can be a useful screening tool to limit infectious outbreaks.

Use of high-flow nasal oxygen (HFNO) for treatment of adults with acute respiratory failure (ARF) has increased.

The American College of Physicians (ACP) developed this guideline to provide clinical recommendations on the appropriate use of point-of-care ultrasonography (POCUS) in patients with acute dyspnea in emergency department (ED) or inpatient settings to improve the diagnostic, treatment, and health outcomes of those with suspected congestive heart failure, pneumonia, pulmonary embolism, pleural effusion, or pneumothorax.

To address high COVID-19 burden in U.S. nursing homes, rapid SARS-CoV-2 antigen tests have been widely distributed in those facilities. However, performance data are lacking, especially in asymptomatic people.
