Public health emergencies have the potential to place enormous strain on health systems. The current pandemic of the novel 2019 coronavirus disease has required hospitals in numerous countries to expand their surge capacity to meet the needs of patients with critical illness. When even surge capacity is exceeded, however, principles of critical care triage may be needed as a means to allocate scarce resources, such as mechanical ventilators or key medications. ⋯ Implementing a triage system requires careful coordination between clinicians, health systems, local and regional governments, and the public, with a goal of transparency to maintain trust. We discuss the principles of tertiary triage and methods for implementing such a system, emphasizing that these systems should serve only as a last resort. Even under triage, we must uphold our obligation to care for all patients as best possible under difficult circumstances.

Randomized controlled trials (RCTs) are considered the highest level of evidence to establish causal associations in clinical research. There are many RCT designs and features that can be selected to address a research hypothesis. Designs of RCTs have become increasingly diverse as new methods have been proposed to evaluate increasingly complex scientific hypotheses. ⋯ To illustrate their diversity, examples of RCTs from the literature are provided. Statistical considerations, such as power and type I error rates, are discussed with the intention of providing practical guidance about how to specify study hypotheses that address the scientific question while being statistically appropriate. Finally, the freely available Consolidated Standards of Reporting Trials guidelines and US Food and Drug Administration guidance documents are introduced, along with a set of guidelines one should consider when planning an RCT or reviewing RCTs submitted for publication in peer-reviewed academic journals.

Guidelines for clinical documentation of evaluation and management face-to-face services were developed > 20 years ago. Recently, the Centers for Medicare & Medicaid Services (CMS) have addressed office and other outpatient services and the corresponding reimbursement, intending to reduce the amount of required documentation and to alleviate clerical burden. A CMS final rule for 2021 will eliminate the history and physical examination as criteria for level of service, allow time or medical decision-making to be used as coding criteria, and will recognize a code for prolonged service. The net effect of these changes may be some decrease in documentation burden, a change in the composition of clinical notes, and greater recognition by CMS of primary care and those who see highly complex patients requiring prolonged services.
