RESUMEN
INTRODUCTION: Septic shock is a severe form of sepsis that has a high mortality rate, and a substantial proportion of these patients will develop cardiac dysfunction, often termed septic cardiomyopathy (SCM). Some SCM patients may develop frank cardiac failure, termed sepsis-related cardiogenic shock (SeRCS). Little is known of SeRCS. This study describes baseline characteristics of patients with SCM and SeRCS compared to patients with septic shock without cardiac dysfunction. We compare clinical outcomes among SCM, SeRCS, and septic shock, and identify risk factors for the development of SCM and SeRCS. METHODS: Septic patients admitted to the ICU with an echocardiogram obtained within 72 hours were included. Left ventricular ejection fraction of ≤55% was used to define SCM, and cardiac index ≤2.1 L/min/m2 among patients with SCM defined SeRCS. Machine learning was used to identify risk factors for development of SCM and SeRCS. Logistic regression was used to compare mortality among groups. RESULTS: Among 1229 patients, 977 patients had septic shock without cardiac dysfunction, 207 had SCM, and 45 had SeRCS. In patients with septic shock, the strongest predictor for developing SCM and SeRCs was a prior history of cardiac dysfunction. Mortality did not significantly differ among the three groups. CONCLUSIONS: SCM and SeRCS affect a minority of patients with septic shock, disproportionately affecting individuals with a history of cardiac disease. We did not identify a mortality difference associated with SCM or SeRCS. Additional work is needed to define further subtypes and treatment options for this patient population.

BACKGROUND: Patients often have high expectations for recovery after critical illness, but the impact of these expectations on subsequent quality of life (QoL) after serious illnesses has not been evaluated empirically. RESEARCH QUESTION: Among adult survivors of acute respiratory failure (ARF), are met vs unmet expectations for health associated with self-reported QoL 6 months after discharge? STUDY DESIGN AND METHODS: This was a prospective longitudinal cohort study enrolling consecutive adult patients with ARF managed in ICUs at five academic medical centers. At hospital discharge, we evaluated participants' expected health 6 months in the future via a visual analog scale (VAS; range, 0-100), with higher scores representing better expected health. At 6-month follow-up, perceived health was assessed using the EQ-5D VAS, and QoL was assessed using the World Health Organization Quality of Life Brief Version (WHOQOL-BREF) instrument. Participants' health expectations were categorized as having been met when perceived health at 6 months was no more than eight points lower than their expectation at study enrollment. The primary analysis compared WHOQOL-BREF domain scores (range, 0-100) at 6 months after discharge in patients with met vs unmet health expectations using the nonparametric Mann-Whitney U test. Secondary analysis modeled WHOQOL-BREF domain scores using multivariate regression, and sensitivity analyses assessed QoL using EQ-5D-5L index values. RESULTS: In the primary analysis, QoL was significantly better among participants with met vs unmet health expectations across all domains of the WHOQOL-BREF: physical health (estimated difference in scores: median, 19 [interquartile range (IQR), 12-15]; P < .001), psychological health (median, 12 [IQR, 6-18]; P < .001), social relationships (median, 6 [IQR, 0-13]; P = .02), and environmental health (median, 12 [IQR, 6-13]; P < .001). In multivariate regression, the difference between expected and perceived health remained associated significantly with the physical health domain score. INTERPRETATION: Fulfillment of health expectations is associated with better QoL after ARF, suggesting a mechanism underpinning successful ICU recovery programs that incorporate normalization and expectation management.

OBJECTIVES: To characterize early unmet nonmedication discharge needs (UDNs), classified as durable medical equipment (DME), home health services (HHS), and follow-up medical appointments (FUAs) and explore their association with 90-day readmission and mortality among survivors of acute respiratory failure (ARF) who were discharged home. DESIGN: Prospective multicenter cohort study. SETTING: Six academic medical centers across United States. PARTICIPANTS: Adult survivors of ARF who required an ICU stay and were discharged home from hospital. INTERVENTIONS: None. Exposure of interest was the proportion of UDN for the following categories: DME, HHS, and FUA ascertained within 7-28 days after hospital discharge. MEASUREMENTS AND MAIN RESULTS: Two hundred eligible patients were recruited between January 2019 and August 2020. One-hundred ninety-five patients were included in the analytic cohort: 118 were prescribed DME, 134 were prescribed HHS, and 189 needed at least one FUA according to discharge plans. 98.4% (192/195) had at least one identified nonmedication need at hospital discharge. Median (interquartile range) proportion of unmet needs across three categories were 0 (0-15%) for DME, 0 (0-50%) for HHS, and 0 (0-25%) for FUA, and overall was 0 (0-20%). Fifty-six patients (29%) had 90-day death or readmission. After adjusting for prespecified covariates, having greater than the median level of unmet needs was not associated with an increased risk of readmission or death within 90 days of discharge (risk ratio, 0.89; 0.51-1.57; p = 0.690). Age, hospital length of stay, Acute Physiology and Chronic Health Evaluation II severity of illness score, and Multidimensional Scale Perceived Social Support score were associated with UDN. CONCLUSIONS: UDN were common among survivors of ARF but not significantly associated a composite outcome of 90-day readmission or death. Our results highlight the substantial magnitude of UDN and identifies areas especially vulnerable to lapses in healthcare coordination.

Rationale: Discussion of patient expectations for recovery is a component of intensive care unit (ICU) follow-up clinics. However, few studies have formally evaluated recovery-related expectations of ICU survivors. Objectives: To estimate the prevalence of unmet expectations for recovery 6 months after hospital discharge among adult survivors of acute respiratory failure (ARF). Methods: This was a prospective, longitudinal, cohort study of survivors of ARF discharged to home from five U.S. medical centers. Expectations for functional recovery were assessed by asking which activities and instrumental activities of daily living (I/ADLs) survivors expected to perform independently at 6 months. Survivors' expectations for overall health status were assessed using a visual analogue scale ranging from 0 to 100. At 6-month follow-up, participants reported which I/ADLs they could perform independently and rated their overall health status using a 100-point visual analogue scale. We defined a participant's functional expectations as being met if they reported independently performing I/ADLs as expected at hospital discharge. Health expectations were considered to be met when self-rated health status at 6 months was no more than 8 points lower than expected at enrollment. Results: Among 180 enrollees, 169 (94%) were alive, and 160 of these (95%) participated in 6-month follow-up. Functional expectations were met for 71% of participating survivors, and overall health expectations were met for 50%. Expectations for functional independence were high, ranging from 87% (housekeeping) to 99% (using a telephone). General health expectations were variable (median, 85; interquartile range [IQR], 75-95). At 6-month follow-up, self-rated, overall health ranged from 2 to 100 (median, 80; IQR, 60-85). In exploratory analyses, participants with met versus unmet expectations differed most in formal education (functional expectations standardized difference = 0.88; health expectations standardized difference = 0.41). Conclusions: Expectations of survivors of ARF about independent functioning were high and generally met, but half had unmet general health expectations 6 months after discharge. It is difficult to predict whose health expectations will be unmet, but possessing less formal education may be a risk factor. Clinical trial registered with www.clinicaltrials.gov (NCT03797313).

INTRODUCTION: Survivors of acute respiratory failure (ARF) commonly experience long-lasting physical, cognitive, and/or mental health impairments. Unmet medication needs occurring immediately after hospital discharge may have an important effect on subsequent recovery. METHODS AND ANALYSIS: In this multicenter prospective cohort study, we enrolled ARF survivors who were discharged directly home from their acute care hospitalization. The primary exposure was unmet medication needs. The primary outcome was hospital readmission or death within 3 months after discharge. We performed a propensity score analysis, using inverse probability weighting for the primary exposure, to evaluate the exposure-outcome association, with an a priori sample size of 200 ARF survivors. RESULTS: We enrolled 200 ARF survivors, of whom 107 (53%) were female and 77 (39%) were people of color. Median (IQR) age was 55 (43-66) years, APACHE II score 20 (15-26) points, and hospital length of stay 14 (9-21) days. Of the 200 participants, 195 (98%) were in the analytic cohort. One hundred fourteen (57%) patients had at least one unmet medication need; the proportion of medication needs that were unmet was 6% (0-15%). Fifty-six (29%) patients were readmitted or died by 3 months; 10 (5%) died within 3 months. Unmet needs were not associated (risk ratio 1.25; 95% CI 0.75-2.1) with hospital readmission or death, although a higher proportion of unmet needs may have been associated with increased hospital readmission (risk ratio 1.7; 95% CI 0.96-3.1) and decreased mortality (risk ratio 0.13; 95% CI 0.02-0.99). DISCUSSION: Unmet medication needs are common among survivors of acute respiratory failure shortly after discharge home. The association of unmet medication needs with 3-month readmission and mortality is complex and requires additional investigation to inform clinical trials of interventions to reduce unmet medication needs. Study registration number: NCT03738774 . The study was prospectively registered before enrollment of the first patient.

Septic shock is a common deadly disease often associated with cardiovascular dysfunction. Left ventricular longitudinal strain (LV LS) has been proposed as a sensitive marker to measure cardiovascular function; however, it is not available universally in standard clinical echocardiograms. We sought to derive a predictive model for LV LS, using machine learning techniques with the hope that we may uncover surrogates for LV LS. We found that left ventricular ejection fraction, tricuspid annular plane systolic excursion, sepsis source, height, mitral valve Tei index, LV systolic dimension, aortic valve ejection time, and peak acceleration rate were all predictive of LV LS in this initial exploratory model. Future modeling work may uncover combinations of these variables which may be powerful surrogates for LV LS and cardiovascular function.

OBJECTIVES: Access to personal health records in an ICU by persons involved in the patient's care (referred to broadly as "family members" below) has the potential to increase engagement and reduce the negative psychologic sequelae of such hospitalizations. Currently, little is known about patient preferences for information sharing with a designated family member in the ICU. We sought to understand the information-sharing preferences of former ICU patients and their family members and to identify predictors of information-sharing preferences. DESIGN: We performed an internet survey that was developed by a broad, multidisciplinary team of stakeholders. Formal pilot testing of the survey was conducted prior to internet survey administration to study subjects. SETTING: Internet survey. SUBJECTS: Subjects included English-speaking adults who had an ICU experience or a family member with ICU experience between 2013 and 2016. We used panel sampling to ensure an ethnically representative sample of the U.S. population. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: One thousand five hundred twenty surveys were submitted, and 1,470 were included in analysis. The majority of respondents (93.6%) stated that they would want to share present and past medical history, either all or that related to their ICU stay, with a designated family member of their choosing. The majority (79%) would also want their designated family member to be able to access that information from a home computer. Although most respondents preferred to share all types of information, they indicated varying levels of willingness to share specific types of more sensitive information. Information-sharing preferences did not differ by age, sex, ethnicity, or type of prior experience in the ICU (i.e., patient or family member). CONCLUSIONS: In the context of an ICU admission, sharing personal health information with a person of the patient's choosing appears desirable for most patients and family members. Policies and implementation of regulations should take this into consideration.

OBJECTIVE: To determine whether heart rate variability (HRV; a physiological measure of acute stress) is associated with persistent psychological distress among family members of adult intensive care unit (ICU) patients. METHODS: This prospective study investigated family members of patients admitted to a study ICU. Participants' variability in heart rate tracings were measured by low frequency (LF)/high frequency (HF) ratio and detrended fluctuation analysis (DFA). Questionnaires were completed 3 months after enrollment to ascertain outcome rates of anxiety, depression, and post-traumatic stress disorder (PTSD). RESULTS: Ninety-nine participants were enrolled (median LF/HF ratio, 0.92 [interquartile range, 0.64-1.38]). Of 92 participants who completed the 3-month follow-up, 29 (32%) had persistent anxiety. Logistic regression showed that LF/HF ratio (odds ratio [OR] 0.85, 95% confidence interval [CI] 0.43, 1.53) was not associated with 3-month outcomes. In an exploratory analysis, DFA α (OR 0.93, 95% CI 0.87, 0.99), α1 (OR 0.97, 95% CI 0.94, 0.99), and α2 (OR 0.94, 95% CI 0.88, 0.99) scaling components were associated with PTSD development. CONCLUSION: Almost one-third of family members experienced anxiety at three months after enrollment. HRV, measured by LF/HF ratio, was not a predictor of psychologic distress, however, exploratory analyses indicated that DFA may be associated with PTSD outcomes.

BACKGROUND: SARS-CoV-2 reinfection and reactivation has mostly been described in case reports. We therefore investigated the epidemiology of recurrent COVID-19 SARS-CoV-2. METHODS: Among patients testing positive for SARS-CoV-2 between March 11 and July 31, 2020 within an integrated healthcare system, we identified patients with a recurrent positive SARS-CoV-2 reverse transcription polymerase chain reaction (RT-PCR) assay ≥60 days after an initial positive test. To assign an overall likelihood of COVID-19 recurrence, we combined quantitative data from initial and recurrent positive RT-PCR cycle thresholds-a value inversely correlated with viral RNA burden- with a clinical recurrence likelihood assigned based on independent, standardized case review by two physicians. "Probable" or "possible" recurrence by clinical assessment was confirmed as the final recurrence likelihood only if a cycle threshold value obtained ≥60 days after initial testing was lower than its preceding cycle threshold or if the patient had an interval negative RT-PCR. RESULTS: Among 23,176 patients testing positive for SARS-CoV-2, 1,301 (5.6%) had at least one additional SARS-CoV-2 RT-PCRs assay ≥60 days later. Of 122 testing positive, 114 had sufficient data for evaluation. The median interval to the recurrent positive RT-PCR was 85.5 (IQR 74-107) days. After combining clinical and RT-PCR cycle threshold data, four patients (3.5%) met criteria for probable COVID-19 recurrence. All four exhibited symptoms at recurrence and three required a higher level of medical care compared to their initial diagnosis. After including six additional patients (5.3%) with possible recurrence, recurrence incidence was 4.3 (95% CI 2.1-7.9) cases per 10,000 COVID-19 patients. CONCLUSIONS: Only 0.04% of all COVID-19 patients in our health system experienced probable or possible recurrence; 90% of repeat positive SARS-CoV-2 RT-PCRs were not consistent with true recurrence. Our pragmatic approach combining clinical and quantitative RT-PCR data could aid assessment of COVID-19 reinfection or reactivation by clinicians and public health personnel.

BACKGROUND In 2019, the US Centers for Disease Control and Prevention (CDC) described the criteria for the diagnosis of e-cigarette or vaping product use-associated lung injury (EVALI), which may be caused by contamination of delta-9-tetrahydrocannabinoid (THC) e-liquids with vitamin E acetate. This report describes a case of a 20-year-old man with a history of recreational drug use that included vaping, who presented with EVALI and a coagulopathy associated with thrombotic events. CASE REPORT We present a 20-year-old patient who worked at a cannabidiol (CBD) manufacturing facility with a history of e-cigarette use and polysubstance abuse in remission who presented with respiratory and gastrointestinal symptoms accompanied by 50-pound weight loss over 6 months. The patient had been vaping with nicotine and THC-containing e-cigarettes multiple times per day for 1.5 years. He met the CDC surveillance criteria for EVALI, consisting of respiratory symptoms and infiltrates on imaging within 90 days of vaping, and was found to have eosinophilic pneumonia secondary to THC-containing e-cigarette use. Additionally, thrombi were detected in the pulmonary arteries, right saphenous vein, and right ventricle. A segmental infarct was noted in the inferior pole of the left kidney. CONCLUSIONS We present the second case report potentially linking e-cigarette use with clinically significant thrombogenesis, the first with both arterial and venous thromboses. This report demonstrates the importance of taking a history of e-cigarette use in patients presenting with lung injury. Although EVALI and the diagnostic criteria have only recently been described, systemic effects, including coagulopathy, are now being reported.

OBJECTIVES: Septic cardiomyopathy develops frequently in patients with sepsis and likely increases short-term mortality. However, whether septic cardiomyopathy is associated with long-term outcomes after sepsis is unknown. We investigated whether septic patients with septic cardiomyopathy have worse long-term outcomes than septic patients without septic cardiomyopathy. DESIGN: Retrospective cohort study. SETTING: Adult ICU. PATIENTS: Adult ICU patients with sepsis. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Left ventricular global longitudinal systolic strain was our primary measure of septic cardiomyopathy. We employed a suite of multivariable survival analyses to explore linear and nonlinear associations between left ventricular global longitudinal systolic strain and major adverse cardiovascular events, which included death, stroke, and myocardial infarction. Our primary outcome was major adverse cardiovascular event through 24 months after ICU discharge. Among 290 study patients, median left ventricular global longitudinal systolic strain was -16.8% (interquartile range, -20.4% to -12.6%), and 38.3% of patients (n = 111) experienced a major adverse cardiovascular event within 24 months after discharge. On our primary, linear analysis, there was a trend (p = 0.08) toward association between left ventricular global longitudinal systolic strain and major adverse cardiovascular event (odds ratio, 1.03; CI, < 1 to 1.07). On our nonlinear analysis, the association was highly significant (p < 0.001) with both high and low left ventricular global longitudinal systolic strain associated with major adverse cardiovascular event among patients with pre-existing cardiac disease. This association was pronounced among patients who were younger (age < 65 yr) and had Charlson Comorbidity Index greater than 5. CONCLUSIONS: Among patients with sepsis and pre-existing cardiac disease who survived to ICU discharge, left ventricular global longitudinal systolic strain demonstrated a U-shaped association with cardiovascular outcomes through 24 months. The relationship was especially strong among younger patients with more comorbidities. These observations are likely of use to design of future trials.

BACKGROUND: Cognitive impairment after sepsis is an important clinical problem. Determinants of postseptic cognitive impairment are not well understood. We thus undertook a systems biology approach to exploring a possible role for apolipoprotein E (APOE) in postseptic cognitive impairment. DESIGN: Prospective, observational cohort. SETTING: Intermountain Medical Center, a tertiary referral center in Utah. PATIENTS/PARTICIPANTS: Patients with sepsis admitted to study intensive care units. INTERVENTIONS: None. METHODS: We obtained peripheral blood for deep sequencing of RNA and followed up survivors at 6 months with a battery of cognitive instruments. We defined cognitive impairment based on the 6-month Hayling test of executive function. In our primary analysis, we employed weighted network analysis. Secondarily, we compared variation in gene expression between patients with normal versus impaired cognition. MEASUREMENTS AND MAIN RESULTS: We enrolled 40 patients, of whom 34 were follow-up eligible and 31 (91%) completed follow-up; 1 patient's RNA sample was degraded-the final analytic cohort was 30 patients. Mean Hayling test score was 5.8 (standard deviation 1.1), which represented 20% with impaired executive function. The network module containing APOE was dominated by low-expression genes, with no association on primary analysis (P = .8). Secondary analyses suggested several potential lines of future investigation, including oxidative stress. CONCLUSIONS: In this prospective pilot cohort, executive dysfunction affected 1 in 5 survivors of sepsis. The APOE gene was sparsely transcribed in peripheral leukocytes and not associated with cognitive impairment. Future lines of research are suggested.

BACKGROUND: Sepsis is a frequently lethal state, commonly associated with left ventricular (LV) dysfunction. Right ventricular (RV) dysfunction in sepsis is less well understood. RESEARCH QUESTION: In septic patients, how common is RV dysfunction, and is it associated with worse outcomes? STUDY DESIGN AND METHODS: We measured echocardiographic parameters on critically ill patients with severe sepsis or septic shock within the first 24 hours of ICU admission. We defined RV dysfunction as fractional area change (FAC) less than 35% or tricuspid annulus systolic plane excursion (TAPSE) less than 1.6 cm. We defined LV systolic dysfunction as ejection fraction (EF) less than 45% or longitudinal strain greater than -19%. Using logistic regression, we assessed the relationship between 28-day mortality and presence of RV dysfunction and LV systolic dysfunction, controlling for receipt of vasopressors, receipt of fluid, mechanical ventilation, and the acute physiology and chronic health evaluation (APACHE II) score. RESULTS: We studied 393 patients. RV and LV dysfunction were common (48% and 63%, respectively). Mean echocardiographic values were: RV end-diastolic area, 22.4 ± 7.0 cm2; RV end-systolic area, 14.2 ± 6.0 cm2; RV FAC, 38 ± 11%; TAPSE, 1.8 ± .06 cm; RV longitudinal strain, -15.3 ± 6.5%; LV EF, 60% ± 14%; LV longitudinal strain, -16.5% ± 6.0%. Patients with RV dysfunction had higher 28-day mortality (31% vs 16%, P = .001). In our multivariable regression model, RV dysfunction was associated with increased mortality (OR, 3.4; CI, 1.7-6.8; P = .001), and LV systolic dysfunction was not (OR, 0.63; CI, 0.3 -1.2; P = .32) INTERPRETATION: Right ventricular dysfunction is present in nearly half of studied septic patients and is associated with over threefold higher 28-day mortality.

INTRODUCTION: As short-term mortality declines for critically ill patients, a growing number of survivors face long-term physical, cognitive and/or mental health impairments. After hospital discharge, many critical illness survivors require an in-depth plan to address their healthcare needs. Early after hospital discharge, numerous survivors experience inadequate care or a mismatch between their healthcare needs and what is provided. Many patients are readmitted to the hospital, have substantial healthcare resource use and experience long-lasting morbidity. The objective of this study is to investigate the gap in healthcare needs occurring immediately after hospital discharge and its association with hospital readmissions or death for survivors of acute respiratory failure (ARF). METHODS AND ANALYSIS: In this multicentre prospective cohort study, we will enrol 200 survivors of ARF in the intensive care unit (ICU) who are discharged directly home from their acute care hospital stay. Unmet healthcare needs, the primary exposure of interest, will be evaluated as soon as possible within 1 to 4 weeks after hospital discharge, via a standardised telephone assessment. The primary outcome, death or hospital readmission, will be measured at 3 months after discharge. Secondary outcomes (eg, quality of life, cognitive impairment, depression, anxiety and post-traumatic stress disorder) will be measured as part of 3-month and 6-month telephone-based follow-up assessments. Descriptive statistics will be reported for the exposure and outcome variables along with a propensity score analysis, using inverse probability weighting for the primary exposure, to evaluate the relationship between the primary exposure and outcome. ETHICS AND DISSEMINATION: The study received ethics approval from Vanderbilt University Medical Center Institutional Review Board (IRB) and the University of Utah IRB (for the Veterans Affairs site). These results will inform both clinical practice and future interventional trials in the field. We plan to disseminate the results in peer-reviewed journals, and via national and international conferences. TRIAL REGISTRATION DETAILS: ClinicalTrials.gov (NCT03738774). Registered before enrollment of the first patient.

BACKGROUND: Family members of patients in intensive care units may experience psychological distress and substantial caregiver burden. OBJECTIVE: To evaluate whether change in caregiver burden from intensive care unit admission to 3-month follow-up is associated with caregiver depression at 3 months. METHODS: Caregiver burden was assessed at enrollment and 3 months later, and caregiver depression was assessed at 3 months. Depression was measured with the Hospital Anxiety and Depression Score. The primary analysis was the association between depression at 3 months and change in caregiver burden, controlling for a history of caregiver depression. RESULTS: One hundred one participants were enrolled; 65 participants had a surviving loved one and completed 3-month follow-up. At 3-month follow-up, 12% of participants met criteria for depression. Increased caregiver burden over time was significantly associated with depression at follow-up (Fisher exact test, P = .004), although this association was not significant after controlling for self-reported history of depression at baseline (Cochran-Mantel-Haenszel test, P = .23). CONCLUSIONS: Family members are increasingly recognized as a vulnerable population susceptible to negative psychological outcomes after a loved one's admission to the intensive care unit. In this small sample, no significant association was found between change in caregiver burden and depression at 3 months after controlling for baseline depression.
