Rationale Intensive care unit (ICU) visitation restrictions during the coronavirus disease (COVID-19) pandemic have drastically reduced family-engaged care. Understanding the impact of physical distancing on family members of ICU patients is needed to inform future policies. Objectives To understand the experiences of family members of critically ill patients with COVID-19 when physically distanced from their loved ones and to explore ways clinicians may support them. Methods This qualitative study of an observational cohort study reports data from 74 family members of ICU patients with COVID-19 at 10 United States hospitals in four states, chosen based on geographic and demographic diversity. Adult family members of patients admitted to the ICU with COVID-19 during the early phase of the pandemic (February–June 2020) were invited to participate in a phone interview. Interviews followed a semistructured guide to assess four constructs: illness narrative, stress experiences, communication experiences, and satisfaction with care. Interviews were transcribed verbatim and analyzed using an inductive approach to thematic analysis. Results Among 74 interviewees, the mean age was 53.0 years, 55% were white, and 76% were female. Physical distancing contributed to substantial stress and harms (nine themes). Participants described profound suffering and psychological illness, unfavorable perceptions of care, and weakened therapeutic relationship between family members and clinicians. Three communication principles emerged as those most valued by family members: contact, consistency, and compassion (the 3Cs). Family members offered suggestions to guide clinicians faced with communicating with physically distanced families. Conclusions Visitation restrictions impose substantial psychological harms upon family members of critically ill patients. Derived from the voics of family members, our findings warrant strong consideration when implementing visitation restrictions in the ICU and advocate for investment in infrastructure (including staffing and videoconferencing) to support communication. This study offers family-derived recommendations to operationalize the 3Cs to guide and improve communication in times of physical distancing during the COVID-19 pandemic and beyond.

BACKGROUND. The airways of obese asthmatics have been shown to be NO deficient, and this contributes to airway dysfunction and reduced response to inhaled corticosteroids. In cultured airway epithelial cells, L-citrulline, a precursor of L-arginine recycling and NO formation, has been shown to prevent asymmetric dimethyl arginine-mediated (ADMA-mediated) NO synthase (NOS2) uncoupling, restoring NO and reducing oxidative stress. METHODS.In a proof-of-concept, open-label pilot study in which participants were analyzed before and after treatment, we hypothesized that 15 g/d L-citrulline for 2 weeks would (a) increase the fractional excretion of NO (FeNO), (b) improve asthma control, and (c) improve lung function. To this end, we recruited obese (BMI >30) asthmatics on controller therapy, with a baseline FeNO of ≤30 ppb from the University of Colorado Medical Center and Duke University Health System. RESULTS.A total of 41 subjects with an average FeNO of 17 ppb (95% CI, 15-19) and poorly controlled asthma (average asthma control questionnaire [ACQ] 1.5 [95% CI, 1.2-1.8]) completed the study. Compared with baseline, L-citrulline increased whereas ADMA and arginase concentration did not (values represent the mean Δ and 95% CI): plasma L-citrulline (190 μM, 84-297), plasma L-arginine (67 μM, 38-95), and plasma L-arginine/ADMA (ratio 117, 67-167). FeNO increased by 4.2 ppb (1.7-6.7 ppb); ACQ decreased by -0.46 (-0.67 to 0.27 points); the forced vital capacity and forced exhalation volume in 1 second, respectively, changed by 86 ml (10-161 ml) and 52 ml (-11 to 132 ml). In a secondary analysis, the greatest FEV 1 increments occurred in those subjects with late-onset asthma (>12 years) (63 ml [95% CI, 1-137]), in females (80 ml [95% CI, 5-154]), with a greater change seen in late-onset females (100 ml, [95% CI, 2-177]). The changes in lung function or asthma control were not significantly associated with the changes before and after treatment in L-arginine/ADMA or FeNO.

IntroductionFew studies have documented the value of mentoring for medical students, and research has been limited to more subjective (e.g., job satisfaction, perceived career preparation) rather than objective outcomes. This study examined whether having a mentor is associated with match outcome (where a student matched based on their rank order list [ROL]).MethodsWe sent a survey link to all emergency medicine (EM) program coordinators to distribute to their residents. EM residents were surveyed about whether they had a mentor during medical school. Match outcome was assessed by asking residents where they matched on their ROL (e.g., first choice, fifth choice). They were also asked about rank in medical school, type of degree (MD vs. DO), and performance on standardized tests. Residents who indicated having a mentor completed the Mentorship Effectiveness Scale (MES), which evaluates behavioral characteristics of the mentor and yields a total score. We assessed correlations among these variables using Pearson’s correlation coefficient. Post-hoc analysis using independent sample t-test was conducted to compare differences in the MES score between those who matched to their first or second choice vs. third or higher choice.ResultsParticipants were a convenience sample of 297 EM residents. Of those, 199 (67%) reported having a mentor during medical school. Contrary to our hypothesis, there was no significant correlation between having a mentor and match outcome (r=0.06, p=0.29). Match outcome was associated with class rank (r=0.13, p=0.03), satisfaction with match outcome (r= −0.37, p<0.001), and type of degree (r=0.12, p=0.04). Among those with mentors, a t-test revealed that the MES score was significantly higher among those who matched to their first or second choice (M=51.31, SD=10.13) compared to those who matched to their third or higher choice (M=43.59, SD=17.12), t(194)=3.65, p<0.001, d=0.55.ConclusionSimply having a mentor during medical school does not impact match outcome, but having an effective mentor is associated with a more favorable match outcome among medical students applying to EM programs.

Rationale Family members of critically ill patients with coronavirus disease (COVID-19) have described increased symptoms of posttraumatic stress disorder (PTSD). Little is known about how these symptoms may change over time. Objectives We studied changes in PTSD symptoms in family members of critically ill patients with COVID-19 over 12 months. Methods This prospective, multisite observational cohort study recruited participants at 12 hospitals in five states. Calls were made to participants at 3–4 months, 6 months, and 12 months after patient admission to the intensive care unit. Results There were 955 eligible family members, of whom 330 (53.3% of those reached) consented to participate. Complete longitudinal data was acquired for 115 individuals (34.8% consented). PTSD symptoms were measured by the IES-6 (Impact of Events Scale-6), with a score of at least 10 identifying significant symptoms. At 3 months, the mean IES-6 score was 11.9 ± 6.1, with 63.6% having significant symptoms, decreasing to 32.9% at 1 year (mean IES-6 score, 7.6 ± 5.0). Three clusters of symptom evolution emerged over time: persistent symptoms (34.8%, n = 40), recovered symptoms (33.0%, n = 38), and nondevelopment of symptoms (32.2%, n = 37). Although participants identifying as Hispanic demonstrated initially higher adjusted IES-6 scores (2.57 points higher [95% confidence interval (CI), 1.1–4.1; P < 0.001]), they also demonstrated a more dramatic improvement in adjusted scores over time (4.7 greater decrease at 12 months [95% CI, 3.2–6.3; P < 0.001]). Conclusions One year later, some family members of patients with COVID-19 continue to experience significant symptoms of PTSD. Further studies are needed to better understand how various differences contribute to increased risk for these symptoms.
