Background: Hyperkalemia can be detected by point-of-care (POC) blood testing and by artificial intelligence- enabled electrocardiography (ECG). These 2 methods of detecting hyperkalemia have not been compared.

Objective: To determine the accuracy of POC and ECG potassium measurements for hyperkalemia detection in patients with critical illness.

Methods: This retrospective study involved intensive care patients in an academic medical center from October 2020 to September 2021. Patients who had 12-lead ECG, POC potassium measurement, and central laboratory potassium measurement within 1 hour were included. The POC potassium measurements were obtained from arterial blood gas analysis; ECG potassium measurements were calculated by a previously developed deep learning model. Hyperkalemia was defined as a central laboratory potassium measurement of 5.5 mEq/L or greater.

Results: Fifteen patients with hyperkalemia and 252 patients without hyperkalemia were included. The POC and ECG potassium measurements were available about 35 minutes earlier than central laboratory results. Correlation with central laboratory potassium measurement was better for POC testing than for ECG (mean absolute errors of 0.211 mEq/L and 0.684 mEq/L, respectively). For POC potassium measurement, area under the receiver operating characteristic curve (AUC) to detect hyperkalemia was 0.933, sensitivity was 73.3%, and specificity was 98.4%. For ECG potassium measurement, AUC was 0.884, sensitivity was 93.3%, and specificity was 63.5%.

Conclusions: The ECG potassium measurement, with its high sensitivity and coverage rate, may be used initially and followed by POC potassium measurement for rapid detection of life-threatening hyperkalemia.

Background: The quality cardiopulmonary resuscitation (CPR) coach role was developed for hospital-based resuscitation teams. This supplementary team member (CPR coach) provides real-time, verbal feedback on chest compression quality to compressors during a cardiac arrest.

Objectives: To evaluate the impact of a quality CPR coach training intervention on resuscitation teams, including presence of coaches on teams and physiologic metrics of quality CPR delivery in real compression events.

Methods: The quality CPR coach curriculum and role implementation were designed and evaluated using a logic model framework. Medical records of patients who had in-unit cardiopulmonary arrests were reviewed retrospectively. Data included physiologic metrics of quality CPR delivery. Analysis included descriptive statistics and comparison of arrest data before and after the intervention.

Results: A total of 79 cardiopulmonary arrests were analyzed: 40 before and 39 after the intervention. Presence of a quality CPR coach on resuscitation teams was more frequent after training, increasing from 35% before the intervention to 72% after (P = .002). No significant difference was found in the frequency of application of Zoll defibrillator pads. Metrics of quality CPR delivery and adherence with American Heart Association recommendations were either unchanged or improved after the intervention.

Conclusions: The quality CPR coach training intervention significantly increased coach presence on code teams, which was associated with clinically significant improvements in some metrics of quality CPR delivery in real cardiopulmonary arrests.

Background: Family satisfaction with intensive care is a measure of patient experience and patient-centered care. Among the factors that might influence family satisfaction are the timing of patient admittance to the intensive care unit (ICU), the ICU environment, and individual health care providers.

Objective: To evaluate family satisfaction with the ICU and to explore associations between satisfaction and specific characteristics of the ICU stay.

Methods: Participants were adult family members of ICU patients. One family member per patient was enrolled. Regression was used to test the association between time or day of admittance and scores on the Family Satisfaction With Care in the Intensive Care Unit survey. Additionally, we explored exposure to admitting physicians and registered nurses. Free-text survey comments were grouped by using qualitative content analysis.

Results: Surveys were completed by 401 family members. There was no association between survey scores and providers, nor between scores and the time or day of the ICU admission. Three major themes emerged as important to patient and family satisfaction: (1) communication and information, (2) personalization or the patient as expert, and (3) staff and environment.

Conclusions: Family satisfaction with an ICU admission was not influenced by the timing of the admission. Overall satisfaction with the ICU was high. The qualitative analysis points to the importance of collecting qualitative data in addition to using standard survey tools to capture the richness of patient experience. Ongoing efforts to engage with families remain critical to the practice of family- and patient-centered care in the ICU.

Background: Moral distress affects the well-being of health care professionals and can lead to burnout and attrition. Assessing moral distress and taking action based on this assessment are important. A new moral conflict assessment (MCA) designed to prompt action was developed and tested.

Objective: To evaluate the utility of the MCA.

Methods: All intensive care unit professionals in 3 hospitals were invited to attend a presentation about the MCA and to participate in semistructured interviews that followed the steps of the MCA. Transcriptions of interviews were interpreted by using qualitative content analysis.

Results: Analysis of individual interviews of 7 participants and 1 focus group of 3 participants revealed that the MCA was a catalyst for expressing feelings and characterizing moral distress, but optimal use required a facilitator. Participants noted that prevention and amelioration of moral distress were determined by organizational culture issues such as consistent understanding of what can be accomplished in the intensive care unit, resolution of power imbalances among staff, and psychological safety to mention moral issues. Structural determinants included disparate work and education schedules between nurses and physicians. Leader determinants included listening to staff and ensuring accountability to address causes and consequences of moral distress. Education and communication were proposed most often as solutions for moral distress.

Conclusions: The evaluation revealed positive and negative features of the MCA. Prevention and amelioration of moral distress require attention to cultural, structural, and leadership issues through education and communication.
