Due to the acuity and time-sensitive needs of their clinical condition, patients presenting with certain emergent pathologies may lack capacity to provide meaningful prospective informed consent to participate in clinical research. For these reasons, these populations have often been excluded from research investigations. To mitigate this, regulations allowing exception from informed consent (EFIC; 21 CFR 50.24) or waiver of informed consent (WIC; 45 CFR 46.101) were developed in 1996. The purpose of this study was to identify trends in the utilization of EFIC and WIC in emergency research. We also sought to describe the disclosure of necessary prestudy regulatory requirements and justification for the use of EFIC/WIC as reported in completed EFIC/WIC clinical trials. ⋯ Since their implementation in 1996, the EFIC/WIC regulations have allowed progress in research aimed at determining optimal care for devastating life-threatening conditions. However, consistent and rigorous report of regulatory prestudy requirements and justification of the use of EFIC/WIC is lacking in clinical trial publications or on websites such as ClinicalTrials.gov. Since research without consent is an ethically sensitive issue and not widely understood, better justification of its needs within the presentation of the research itself may educate the general medical community and also reduce concerns about whether or not the regulations are being properly applied.

The ability of emergency physicians (EPs) to identify hydronephrosis using point-of-care ultrasound (POCUS) has been assessed in the past using computed tomography (CT) scans as the reference standard. We aimed to determine the ability of EPs to identify and grade hydronephrosis on POCUS using the consensus interpretation of POCUS by emergency radiologists as the reference standard. ⋯ Emergency physicians were found to have moderate to high sensitivity for identifying hydronephrosis on POCUS when compared with the consensus interpretation of the same studies by emergency radiologists. These POCUS findings by EPs produced more definitive results when at least moderate degree of hydronephrosis was present.

Observational Study
Development and Validation of a Measure to Assess Patients' Threat Perceptions in the Emergency Department.
Threat perceptions in the emergency department (ED; e.g., patients' subjective feelings of helplessness or lack of control) during evaluation for an acute coronary syndrome (ACS) are associated with the development of posttraumatic stress disorder (PTSD), and PTSD has been associated with medication nonadherence, cardiac event recurrence, and mortality. This study reports the development and validation of a seven-item measure of ED threat perceptions in English- and Spanish-speaking patients evaluated for ACS. ⋯ This brief tool assessing ED threat perceptions has clinical utility for providers to identify patients at risk for developing cardiac-induced PTSD and is critical to inform research on whether threat may be modified in-ED to reduce PTSD incidence.

Multicenter Study
Patient Preferences Regarding Shared Decision Making in the Emergency Department: Findings From a Multisite Survey.
As shared decision making (SDM) has received increased attention as a method to improve the patient-centeredness of emergency department (ED) care, we sought to determine patients' desired level of involvement in medical decisions and their perceptions of potential barriers and facilitators to SDM in the ED. ⋯ We found that the majority of ED patients in our large, diverse sample wanted to be involved in medical decisions, especially in the case of a "serious" medical problem, and felt that they had the ability to do so. Nevertheless, many patients were unlikely to actively seek involvement and defaulted to allowing the physician to make decisions during the ED visit. After fully explaining the consequences of a decision, clinicians should make an effort to explicitly ascertain patients' desired level of involvement in decision making.

Interruptions can adversely impact human performance, particularly in fast-paced and high-risk environments such as the emergency department (ED). Understanding physician behaviors before, during, and after interruptions is important to the design and promotion of safe and effective workflow solutions. However, traditional human factors-based interruption models do not accurately reflect the complexities of real-world environments like the ED and may not capture multiple interruptions and multitasking. ⋯ Using this framework provides a more detailed description of physician behaviors in complex environments. Understanding the different types of interruption and resumption patterns, which may have a different impact on performance, can support the design of interruption mitigation strategies.
