ImportanceOverall, 1 in 3 family caregivers of patients who require intensive care unit (ICU) admission will experience significant posttraumatic stress symptoms (PTSSs), but little is known about how PTSSs evolve over time. Measuring PTSS trajectories could facilitate the development of targeted interventions to improve mental health outcomes for family caregivers of critically ill patients.ObjectiveTo measure 6-month PTSS trajectories among caregivers of patients with acute cardiorespiratory failure.Design, Setting, and ParticipantsThis prospective cohort study was conducted in the medical ICU of a large academic medical center among adult patients requiring (1) vasopressors for shock, (2) high-flow nasal cannula, (3) noninvasive positive pressure ventilation, or (4) invasive mechanical ventilation. Each patient was enrolled along with their primary caregiver, ie, the unpaid individual who provided the most physical, emotional, or financial support prior to ICU admission.Main Outcomes and MeasuresFamily caregiver PTSSs were assessed using the Impact of Events Scale–Revised within 48 hours of ICU admission, following ICU discharge, and 3 and 6 months after enrollment. Latent class growth analysis was used to measure PTSS trajectories. Preselected patient and caregiver characteristics measured at ICU admission were analyzed for association with trajectory membership. Six-month patient and caregiver outcomes were analyzed by caregiver trajectory.ResultsOverall, 95 family caregivers were enrolled and provided baseline data; mean (SD) age was 54.2 (13.6) years, 72 (76%) were women, 22 (23%) were Black individuals, and 70 (74%) were White individuals. Three trajectories were identified: persistently low (51 caregivers [54%]), resolving (29 [31%]), and chronic (15 [16%]). Low caregiver resilience, prior caregiver trauma, high patient severity of illness, and good patient premorbid functional status were associated with the chronic trajectory. Caregivers with the chronic PTSS trajectory had worse 6-month health-related quality of life (mean [SD] total 36-item Short Form Survey score, persistently low trajectory: 104.7 [11.3]; resolving trajectory: 101.7 [10.4]; chronic trajectory: 84.0 [14.4]; P P = .009).Conclusions and RelevanceIn this study, 3 distinct PTSS trajectories among ICU family caregivers were observed, with 16% of caregivers experiencing chronic PTSSs over the subsequent 6 months. Family caregivers with persistent PTSS had lower resilience, prior trauma, higher patient severity of illness, and higher baseline patient functional status compared with family caregivers with persistently low PTSS, with adverse effects on quality of life and work. Identifying these caregivers is an essential first step to develop interventions tailored to those with the greatest need for support.

CONTEXT. Severe Acute Brain Injury (SABI) is neurologically devastating, and surrogates for these patients may struggle with particularly complex decisions due to substantial prognostic uncertainty. OBJECTIVES. To compare anxiety and depression symptoms over time between SABI surrogates and non-SABI surrogates for patients requiring prolonged mechanical ventilation (PMV). METHODS. We conducted a secondary analysis of the data from a multicenter randomized trial of a decision aid intervention for surrogates of adults experiencing PMV. Eligible patients were enrolled from medical, surgical, trauma, cardiac, and neurologic intensive care units (ICUs). ICU admitting diagnoses were used to identify patients experiencing SABI. We compared anxiety and depression symptoms as measured by the Hospital Anxiety and Depression Scale score 6 months after trial enrollment between surrogates of patients with SABI and surrogates of patients experiencing PMV for other reasons. RESULTS. Our analysis included 206 patients, 60 (29%) with SABI and 146 (71%) without SABI, and their primary surrogate decision makers. After adjusting for potential confounders including surrogate demographics, surrogate financial distress, patient severity of illness baseline GCS, and patient health status at 6 months, we found that surrogates of patients experiencing SABI had higher symptoms of anxiety and depression than surrogates of non-SABI patients (adjusted mean difference 3.6, 95% CI 1.2–6.0). CONCLUSION. Surrogates of PMV patients with SABI experience persistently elevated anxiety and depression symptoms over 6 months compared to surrogates of PMV patients without SABI. Further work is needed to understand contributors to prolonged distress in this higher risk population.

Purpose To obtain information on how family visitor restriction during the COVID-19 pandemic has impacted the workplace experience of physicians and nurses in the medical intensive care unit, and to assess differences by profession. Materials and methods We developed a survey containing closed- and open-ended questions, applying both quantitative and qualitative analyses to our results. Results Of the 74 respondents, 29 (38%) were nurses and 45 (62%) were physicians. Nurses reported positive changes to daily workflow and the ability to provide medical care, while physicians reported negative changes in these areas. Both groups reported decreased comprehension and increased distress among families, and decreased ability to provide end-of-life care. For the qualitative analysis, eight themes were identified: the patient’s room as space, creation of a new space through virtual communication, time, increased complexity of care, challenges around the use of technology, adjustments to team roles and responsibilities, desire for families to return, and internal tension. Conclusion Intensive care physicians and nurses reported both positive and negative effects of family visitor restriction during the COVID-19 pandemic, with significant differences based on profession. Both groups expressed concern for an overall negative impact of visitor restriction on healthcare workers, patients, and their families.

Rationale: Inhaled treprostinil may improve oxygenation and have additional antiinflammatory effects in early acute hypoxemic respiratory failure, potentially preventing or reducing the severity of acute respiratory distress syndrome (ARDS).Objectives: To determine whether administration of inhaled treprostinil to patients at risk for ARDS is feasible, safe, and efficacious.Methods: We performed a double-blind, placebo-controlled, single-center randomized pilot trial at a quaternary care academic medical center. Patients with acute hypoxemia due to pneumonia or signs of low-pressure pulmonary edema with a unilateral or bilateral infiltrate on chest imaging and a 4 L/min supplemental oxygen requirement not requiring positive pressure ventilation were evaluated. Randomized patients received study drug or placebo (2:1 ratio). Treatment was initiated at 6 breaths every 4 hours and titrated up to 12 breaths. Subjects were maintained on treatment for 7 days and then tapered off over a period of 4 days. Study drug was stopped if positive pressure ventilation was required (invasive or noninvasive).Results: Fourteen patients were enrolled over a period of 31 months. Baseline characteristics were not significantly different between treatment groups with respect to age, sex, race, Acute Physiologic Assessment and Chronic Health Evaluation score, lung injury prediction score, or baseline mean oxygen saturation as measured by pulse oximetry (SpO2):fraction of inspired oxygen (FiO2) ratio. Trends in daily baseline and 30-minute postdose SpO2:FiO2 ratio for all treatment points were not significantly different between placebo and treprostinil. Four patients required positive pressure ventilation in the treprostinil group versus one in the placebo group.Conclusions: Inhaled treprostinil administration is feasible in patients at risk for ARDS but was not associated with improvement in the SpO2:FiO2 ratio relative to placebo. Drug-associated adverse events were not severe nor unexpected based on the known adverse effect profile of inhaled treprostinil. The clinical benefit of this intervention is unclear at this time in the absence of larger studies.Clinical trial registered with Clinicaltrials.gov (NCT02370095).

PURPOSE: To identify specific components of ICU clinician supportive care and communication that are associated with increased post-traumatic stress disorder (PTSD) symptoms for surrogate decision makers of patients with chronic critical illness (CCI). METHODS: We conducted a secondary analysis of data from a randomized controlled trial of palliative care-led meetings to provide information and support for CCI surrogates. The primary outcome for this secondary analysis was PTSD symptoms at 90 days, measured by the Impact of Event Scale-Revised (IES-R). Caregiver perceptions of clinician support and communication were assessed using a version of the After-Death Bereaved Family Member Interview (ADBFMI) instrument modified for use in non-bereaved in addition to bereaved caregivers. The association between ADBFMI items and IES-R score was analyzed using multiple linear regression. RESULTS: 90-day follow up was complete for 306 surrogates corresponding to 224 patients. 71% of surrogates were female and mean age was 51 years. Of the domains, negative perception of the patient’s physical comfort and emotional support was associated with the greatest increase in surrogate PTSD symptoms (beta coefficient 1.74, 95% CI 0.82 to 2.65). The three specific preselected items associated with increased surrogate PTSD symptoms were surrogate perception that clinicians did not listen to concerns (beta coefficient 10.7, 95% CI 3.6 to 17.9), failure of the physician to explain how the patient’s pain would be treated (beta coefficient 12.1, 95% CI 4.9 to 19.3), and lack of sufficient religious contact (beta coefficient 11.7, 95% CI 2 to 21.3). CONCLUSION: Modifiable deficits in ICU clinician support and communication were associated with increased PTSD symptoms among CCI surrogates.

Background Lidocaine is used to alleviate procedural pain but paradoxically increases pain during injection. Pain perception can be modulated by non-noxious stimuli such as temperature or touch according to the gate control theory of pain. We postulated that lidocaine dripped onto the skin prior to injection would cool or add the sensation of touch at the skin surface to reduce pain perception from the procedure. Methods A randomized clinical trial of patients referred to the procedure service from February 2011 through March 2015 was conducted. All patients received 1% subcutaneous lidocaine injection. Patients randomized to the intervention group had approximately 1 to 2 ml of lidocaine squirted onto the skin surface prior to subcutaneous lidocaine injection. Patients were blinded to the details of the intervention and were surveyed by a blinded investigator to document the primary outcome (severity of pain from the procedure) using a visual analog scale. Results A total of 481 patients provided consent and were randomized to treatment. There was a significant improvement in the primary outcome of procedural pain (control, 16.6 ± 24.8 mm vs 12.2 ± 19.4 mm; P = .03) with the intervention group as assessed by using the visual analog scale score. Pain scores were primarily improved for peripherally inserted central catheters (control, 18.8 ± 25.6 mm vs 12.2 ± 18.2 mm; P = .02) upon subgroup analysis. Conclusions Bedside procedures are exceedingly common. Data regarding the severity of procedural pain and strategies to mitigate it are important for the informed consent process and patient satisfaction. Overall, pain reported from common bedside procedures is low, but pain can be further reduced with the addition of lidocaine onto the skin surface to modulate pain perception.

BACKGROUND Previous research investigating the impact of delayed intensive care unit (ICU) transfer on outcomes has utilized subjective criteria for defining critical illness. OBJECTIVE To investigate the impact of delayed ICU transfer using the electronic Cardiac Arrest Risk Triage (eCART) score, a previously published early warning score, as an objective marker of critical illness. DESIGN Observational cohort study. SETTING Medical-surgical wards at 5 hospitals between November 2008 and January 2013. PATIENTS Ward patients. INTERVENTION None. MEASUREMENTS eCART scores were calculated for all patients. The threshold with a specificity of 95% for ICU transfer (eCART ≥ 60) denoted critical illness. A logistic regression model adjusting for age, sex, and surgical status was used to calculate the association between time to ICU transfer from first critical eCART value and in-hospital mortality. RESULTS A total of 3789 patients met the critical eCART threshold before ICU transfer, and the median time to ICU transfer was 5.4 hours. Delayed transfer (>6 hours) occurred in 46% of patients (n = 1734) and was associated with increased mortality compared to patients transferred early (33.2% vs 24.5%, P

Rationale: Chronically critically ill patients are often dependent on family members for surrogate decision-making, and these surrogates are at high risk for emotional distress. We hypothesized that patient- and surrogate-specific risk factors for surrogate post-traumatic stress disorder (PTSD) symptoms can be identified early in the course of chronic critical illness. Objectives: To identify risk factors for PTSD symptoms in surrogate decision-makers of chronically critically ill patients. Methods: We performed a secondary analysis of the database from a multicenter randomized trial of a communication intervention for chronic critical illness patients and surrogates. Variables preselected for plausible mechanism for increasing PTSD symptoms and identifiable by Day 10 of mechanical ventilation were included in the analysis for association with surrogate PTSD symptoms at 90 days, as measured by the Impact of Events Score–Revised (IES-R). Patient factors included demographics, insurance status, baseline functional status, chronic comorbidities, illness severity, and presence of advance directive. Surrogate variables included demographics, education level and employment, religion, relationship to patient, and Hospital Anxiety and Depression Scale score measured at enrollment. Multivariable linear regression models were then constructed for 26 potential risk factors, including biologically or mechanistically plausible confounders for each, with IES-R score as the outcome. All models were adjusted for multiple respondents, using a mixed model, considering the patients as a random factor. Results: Our analysis included 306 surrogates for 224 patients. A total of 49% of patients were female, and mean age was 59 years (95% confidence interval [CI], 56.4–60.7). A total of 71% of surrogates were female, and mean age was 51 years (95% CI, 49.3–52.4). After examining each potential risk factor in a separate multivariable model, only Day-10 surrogate Hospital Anxiety and Depression Scale score (β coefficient = 1.02; 95% CI, 0.73–1.30) and patient unresponsiveness (β coefficient = 8.39; 95% CI, 0.83–15.95) were associated with higher IES-R scores. Conclusions: Among surrogate decision-makers for chronically critically ill patients, high anxiety and depression scores and patient unresponsiveness on or near Day 10 of mechanical ventilation are risk factors for PTSD symptoms at 90 days.

Purpose: Intermediate care units (IMCUs) represent an alternative care setting with nurse staffing levels between those of the general ward and the intensive care unit (ICU). Despite rising prevalence, little is known about IMCU practices across US hospitals. The purpose of this study is to characterize utilization patterns and assess for variation. Materials and Methods: A 14-item survey was distributed to a random nationwide sample of pulmonary and critical care physicians between January and April 2017. Results: A total of 51 physicians from 24 different states completed the survey. Each response represented a unique institution, the majority of which were public (59%), academic (73%), and contained at least 1 IMCU (65%). Of the IMCUs surveyed, 58% operated as 1 mixed unit that admitted medical, cardiac, and surgical patients as opposed to having separate subspecialty units. Ninety-one percent of units admitted step-down patients from the ICU, but 39% of units accepted a mix of step-up patients, step-down patients, postoperative patients, and patients from the emergency department. Intensivists managed care in 21% of units whereas 36% had no intensivist involvement. Conclusion: Organization practices vary considerably between IMCUs across institutions. The impact of different organization practices on patient outcomes should be assessed.
