RESUMO
Background: Severe alcohol withdrawal syndrome (SAWS) is highly morbid, costly, and common among hospitalized patients, yet minimal evidence exists to guide inpatient management. Research needs in this field are broad, spanning the translational science spectrum. Goals: This research statement aims to describe what is known about SAWS, identify knowledge gaps, and offer recommendations for research in each domain of the Institute of Medicine T0-T4 continuum to advance the care of hospitalized patients who experience SAWS. Methods: Clinicians and researchers with unique and complementary expertise in basic, clinical, and implementation research related to unhealthy alcohol consumption and alcohol withdrawal were invited to participate in a workshop at the American Thoracic Society 2019 International Conference. The committee was subdivided into four groups on the basis of interest and expertise: T0-T1 (basic science research with translation to humans), T2 (research translating to patients), T3 (research translating to clinical practice), and T4 (research translating to communities). A medical librarian conducted a pragmatic literature search to facilitate this work, and committee members reviewed and supplemented the resulting evidence, identifying key knowledge gaps. Results: The committee identified several investigative opportunities to advance the care of patients with SAWS in each domain of the translational science spectrum. Major themes included 1) the need to investigate non-γ-aminobutyric acid pathways for alcohol withdrawal syndrome treatment; 2) harnessing retrospective and electronic health record data to identify risk factors and create objective severity scoring systems, particularly for acutely ill patients with SAWS; 3) the need for more robust comparative-effectiveness data to identify optimal SAWS treatment strategies; and 4) recommendations to accelerate implementation of effective treatments into practice. Conclusions: The dearth of evidence supporting management decisions for hospitalized patients with SAWS, many of whom require critical care, represents both a call to action and an opportunity for the American Thoracic Society and larger scientific communities to improve care for a vulnerable patient population. This report highlights basic, clinical, and implementation research that diverse experts agree will have the greatest impact on improving care for hospitalized patients with SAWS.

BACKGROUND: Timely initiation of physical, occupational, and speech therapy in critically ill patients is crucial to reduce morbidity and improve outcomes. Over a 5-year time interval, we sought to determine the utilization of these rehabilitation therapies in the USA. METHODS: We performed a retrospective cohort study utilizing a large, national administrative database including ICU patients from 591 hospitals. Patients over 18 years of age with acute respiratory failure requiring invasive mechanical ventilation within the first 2 days of hospitalization and for a duration of at least 48 h were included. RESULTS: A total of 264,137 patients received invasive mechanical ventilation for a median of 4.0 [2.0-8.0] days. Overall, patients spent a median of 5.0 [3.0-10.0] days in the ICU and 10.0 [7.0-16.0] days in the hospital. During their hospitalization, 66.5%, 41.0%, and 33.2% (95% CI = 66.3-66.7%, 40.8-41.2%, 33.0-33.4%, respectively) received physical, occupational, and speech therapy. While on mechanical ventilation, 36.2%, 29.7%, and 29.9% (95% CI = 36.0-36.4%, 29.5-29.9%, 29.7-30.1%) received physical, occupational, and speech therapy. In patients receiving therapy, their first physical therapy session occurred on hospital day 5 [3.0-8.0] and hospital day 6 [4.0-10.0] for occupational and speech therapy. Of all patients, 28.6% (95% CI = 28.4-28.8%) did not receive physical, occupational, or speech therapy during their hospitalization. In a multivariate analysis, patients cared for in the Midwest and at teaching hospitals were more likely to receive physical, occupational, and speech therapy (all P < 0.05). Of patients with identical covariates receiving therapy, there was a median of 61%, 187%, and 70% greater odds of receiving physical, occupational, and speech therapy, respectively, at one randomly selected hospital compared with another (median odds ratio 1.61, 2.87, 1.70, respectively). CONCLUSIONS: Physical, occupational, and speech therapy are not routinely delivered to critically ill patients, particularly while on mechanical ventilation in the USA. The utilization of these therapies varies according to insurance coverage, geography, and hospital teaching status, and at a hospital level.

OBJECTIVES: To assess the impact of a discharge diagnosis of critical illness polyneuromyopathy on health-related outcomes in a large cohort of patients requiring ICU admission. DESIGN: Retrospective cohort with propensity score-matched analysis. SETTING: Analysis of a large multihospital database. PATIENTS: Adult ICU patients without preexisting neuromuscular abnormalities and a discharge diagnosis of critical illness polyneuropathy and/or myopathy along with adult ICU propensity-matched control patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 3,567 ICU patients with a discharge diagnosis of critical illness polyneuropathy and/or myopathy, we matched 3,436 of these patients to 3,436 ICU patients who did not have a discharge diagnosis of critical illness polyneuropathy and/or myopathy. After propensity matching and adjusting for unbalanced covariates, we used conditional logistic regression and a repeated measures model to compare patient outcomes. Compared to patients without a discharge diagnosis of critical illness polyneuropathy and/or myopathy, patients with a discharge diagnosis of critical illness polyneuropathy and/or myopathy had fewer 28-day hospital-free days (6 [0.1] vs 7.4 [0.1] d; p < 0.0001), had fewer 28-day ventilator-free days (15.7 [0.2] vs 17.5 [0.2] d; p < 0.0001), had higher hospitalization charges (313,508 [4,853] vs 256,288 [4,470] dollars; p < 0.0001), and were less likely to be discharged home (15.3% vs 32.8%; p < 0.0001) but had lower in-hospital mortality (13.7% vs 18.3%; p < 0.0001). CONCLUSIONS: In a propensity-matched analysis of a large national database, a discharge diagnosis of critical illness polyneuropathy and/or myopathy is strongly associated with deleterious outcomes including fewer hospital-free days, fewer ventilator-free days, higher hospital charges, and reduced discharge home but also an unexpectedly lower in-hospital mortality. This study demonstrates the clinical importance of a discharge diagnosis of critical illness polyneuropathy and/or myopathy and the need for effective preventive interventions.

BACKGROUND: Although alcohol misuse is associated with deleterious outcomes in critically ill patients, its detection by either self-report or examination of biomarkers is difficult to obtain consistently. Phosphatidylethanol (PEth) is a direct alcohol biomarker that can characterize alcohol consumption patterns; however, its diagnostic accuracy in identifying misuse in critically ill patients is unknown. METHODS: PEth values were obtained in a mixed cohort comprising 122 individuals from medical and burn intensive care units (n = 33), alcohol detoxification unit (n = 51), and healthy volunteers (n = 38). Any alcohol misuse and severe misuse were referenced by Alcohol Use Disorders Identification Test (AUDIT) and AUDIT-C scores separately. Mixed-effects logistic regression analysis was performed, and the discrimination of PEth was evaluated using the area under the receiver-operating characteristic (ROC) curve. RESULTS: The area under the ROC curve for PEth was 0.927 (95% CI: 0.877, 0.977) for any misuse and 0.906 (95% CI: 0.850, 0.962) for severe misuse defined by AUDIT. By AUDIT-C, the area under the ROC curves was 0.948 (95% CI: 0.910, 0.956) for any misuse and 0.913 (95% CI: 0.856, 0.971) for severe misuse. The PEth cut-points of ≥250 and ≥400 ng/ml provided optimal discrimination for any misuse and severe misuse, respectively. The positive predictive value for ≥250 ng/ml was 88.7% (95% CI: 77.5, 95.0), and the negative predictive value was 86.7% (95% CI: 74.9, 93.7). PEth ≥ 400 ng/ml achieved similar values, and similar results were shown for AUDIT-C. In a subgroup analysis of critically ill patients only, test characteristics were similar to the mixed cohort. CONCLUSIONS: PEth is a strong predictor and has good discrimination for any and severe alcohol misuse in a mixed cohort that includes critically ill patients. Cut-points at 250 ng/ml for any, and 400 ng/ml for severe, are favorable. External validation will be required to establish these cut-points in critically ill patients.

BACKGROUND: The association between alcohol misuse and the need for intensive care unit admission as well as hospital readmission among those discharged from the hospital following a critical illness is unclear. This study sought to determine whether alcohol misuse was associated with (1) admission to an intensive care unit (ICU) among a cohort of patients receiving outpatient care and (2) hospital readmission among those discharged from the hospital following critical illness. METHODS: This was a retrospective cohort study conducted with data from 24 Veterans Affairs (VA) health care facilities between 2004 and 2007. Scores on the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) questionnaire were used to identify patients with past-year abstinence, lower-risk alcohol use, moderate alcohol misuse, or severe alcohol misuse. The primary outcome was admission to a VA intensive care unit within the year following administration of the AUDIT-C. In an analysis focused on patients discharged from the ICU, the 2 main outcomes were hospital readmission within 1 year and within 30 days. RESULTS: Among 486,115 veterans receiving outpatient care, the adjusted probability of ICU admission within 1 year was 2.0% (95% confidence interval [CI]: 1.7%-2.3%) for abstinent patients, 1.6% (95% CI: 1.3%-1.8%) for patients with lower-risk alcohol use, 1.8% (1.4%-2.3%) for patients with moderate alcohol misuse, and 2.5% (2.0%-2.9%) for patients with severe alcohol misuse. Among the 9,030 patients discharged from an ICU, the adjusted probability of hospital readmission within 1 year was 48% (46%-49%) in abstinent patients, 44% (42%-45%) in patients with lower-risk alcohol use, 42% (39%-45%) in patients with moderate alcohol misuse, and 55% (49%-60%) in patients with severe alcohol misuse. CONCLUSIONS: Alcohol misuse may represent a modifiable risk factor for a cycle of ICU admission and subsequent hospital readmission.

OBJECTIVES: Alcohol use disorders are common among patients admitted to an ICU, yet systematic screening is rarely performed. We sought to confirm the construct validity of the full Alcohol Use Disorders Identification Test and to evaluate the performance of the brief three-item Alcohol Use Disorders Identification Test-C using the full Alcohol Use Disorders Identification Test as a proxy gold standard in a population of patients with a medical critical illness. DESIGN: Secondary analysis. SETTING: The acute respiratory distress syndrome network, a consortium of 12 university centers (44 hospitals) dedicated to conducting multicenter clinical trials in patients with acute respiratory distress syndrome. SUBJECTS: Patients meeting consensus criteria for acute respiratory distress syndrome. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 1,133 patients enrolled in one of three acute respiratory distress syndrome network studies, 1,037 (92%) had full Alcohol Use Disorders Identification Test data available. Of the included patients, 236 (23%) scored above the screening threshold for an alcohol use disorder on the full Alcohol Use Disorders Identification Test. Construct validity analysis of the full Alcohol Use Disorders Identification Test supported a three-factor model. Compared with the full Alcohol Use Disorders Identification Test, the Alcohol Use Disorders Identification Test -C had an area under the receiver operating characteristic curve of 0.99 for men and 0.98 for women. The optimal cutoff was 4 for both genders. At this cutoff, the Alcohol Use Disorders Identification Test -C had a sensitivity of 95% (95% CI, 92-98%) and specificity of 94% (95% CI, 92-96%) for men and sensitivity of 89% (95% CI, 82-96%) and specificity of 99% (95% CI, 98-100%) for women. CONCLUSIONS: Although a three-factor structure for the Alcohol Use Disorders Identification Test was confirmed in ICU patients with acute respiratory distress syndrome, the first three questions focusing on alcohol consumption provide information that is comparable with the full 10-item Alcohol Use Disorders Identification Test screening questionnaire. This study is limited by the lack of a true gold standard, and the performance of the Alcohol Use Disorders Identification Test -C is likely overestimated due to this limitation.

BACKGROUND: Severity of alcohol withdrawal syndrome (AWS) is associated with hospital mortality and length of stay. However, as there is no consensus regarding how to predict the development of severe alcohol withdrawal syndrome (SAWS), we sought to determine independent predictors of SAWS. METHODS: We conducted a systematic review and meta-analysis of studies evaluating hospitalized patients with AWS versus SAWS-delirium tremens (DT) and/or seizures. Random-effects meta-analysis [PRISMA guidelines] was performed on common baseline variables and predictive effects for development of SAWS were calculated using RevMan v5.2. Funnel plots were constructed, and tests of heterogeneity were performed. RESULTS: Of 226 studies screened, 17 met criteria and 15 were included in the meta-analysis. The primary findings were that an incident occurrence of DT or alcohol withdrawal seizures was significantly predicted by history of a similar event (OR 2.58 for DT vs. no-DT, 95% CI 1.41, 4.7; OR 2.8 for seizure vs. no-seizure, 95% CI 1.09, 7.19). Both a lower initial platelet count and serum potassium level were predictive of an incident occurrence of DT (platelet count mean difference [MD] -45.64/mm(3) vs. no-DT, 95% CI -75.95, -15.33; potassium level MD -0.26 mEq/l vs. no-DT, 95% CI -0.45, -0.08), seizures, and SAWS. Higher initial alanine aminotransferase was seen in patients with SAWS (MD 20.97 U/l vs. no-SAWS, 95% CI 0.89, 41.05). Higher initial serum gamma-glutamyl transpeptidase was seen in patients with incident alcohol withdrawal seizures (MD 202.56 U/l vs. no-seizure, 95% CI 3.62, 401.5). Significant heterogeneity was observed, and there was evidence of publication bias. Notably, neither gender nor comorbid liver disease was predictive. CONCLUSIONS: The course of prior episodes of AWS is the most reliable predictor of subsequent episodes. Thrombocytopenia and hypokalemia also correlate with SAWS. We propose further research into drinking patterns, gender, and medical comorbidities.

OBJECTIVES: The effects of excess alcohol consumption (alcohol misuse) on outcomes in patients with acute lung injury have been inconsistent, and there are no studies examining this association in the era of low tidal volume ventilation and a fluid conservative strategy. We sought to determine whether validated scores on the Alcohol Use Disorders Identification Test that correspond to past-year abstinence (zone 1), low-risk drinking (zone 2), mild to moderate alcohol misuse (zone 3), and severe alcohol misuse (zone 4) are associated with poor outcomes in patients with acute lung injury. DESIGN: Secondary analysis. SETTING: The Acute Respiratory Distress Syndrome Network, a consortium of 12 university centers (44 hospitals) dedicated to the conduct of multicenter clinical trials in patients with acute lung injury. SUBJECTS: Patients meeting consensus criteria for acute lung injury enrolled in one of three recent Acute Respiratory Distress Syndrome Network clinical trials. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 1,133 patients enrolled in one of three Acute Respiratory Distress Syndrome Network studies, 1,037 patients had an Alcohol Use Disorders Identification Test score available for analysis. Alcohol misuse was common with 70 (7%) of patients having Alcohol Use Disorders Identification Test scores in zone 3 and 129 (12%) patients in zone 4. There was a U-shaped association between validated Alcohol Use Disorders Identification Test zones and death or persistent hospitalization at 90 days (34% in zone 1, 26% in zone 2, 27% in zone 3, 36% in zone 4; p < 0.05 for comparison of zone 1 to zone 2 and zone 4 to zone 2). In a multiple logistic regression model, there was a significantly higher odds of death or persistent hospitalization in patients having Alcohol Use Disorders Identification Test zone 4 compared with those in zone 2 (adjusted odds ratio 1.70; 95% confidence interval 1.00, 2.87; p = 0.048). CONCLUSIONS: Severe but not mild to moderate alcohol misuse is independently associated with an increased risk of death or persistent hospitalization at 90 days in acute lung injury patients.

BACKGROUND: Rehospitalization is an important and costly outcome that occurs commonly in several diseases encountered in the medical intensive care unit (ICU). Although alcohol use disorders are present in 40% of ICU survivors and alcohol withdrawal is the most common alcohol-related reason for admission to an ICU, rates and predictors of rehospitalization have not been previously reported in this population. METHODS: We conducted a retrospective cohort study of medical ICU survivors with a primary or secondary discharge diagnosis of alcohol withdrawal using 2 administrative databases. The primary outcome was time to rehospitalization or death. Secondary outcomes included time to first emergency department or urgent care clinic visit in the subset of ICU survivors who were not rehospitalized. Cox proportional hazard models were adjusted for age, gender, race, homelessness, smoking, and payer source. RESULTS: Of 1,178 patients discharged from the medical ICU over the study period, 468 (40%) were readmitted to the hospital and 54 (4%) died within 1 year. Schizophrenia (hazard ratio 2.23, 95% CI 1.57, 3.34, p < 0.001), anxiety disorder (hazard ratio 2.04, 95% CI 1.30, 3.32, p < 0.01), depression (hazard ratio 1.62, 95% CI 1.05, 2.40, p = 0.03), and Deyo comorbidity score ≥3 (hazard ratio 1.43, 95% CI 1.09, 1.89, p = 0.01) were significant predictors of time to death or first rehospitalization. Bipolar disorder was associated with time to first emergency department or urgent care clinic visit (hazard ratio 2.03, 95% CI 1.24, 3.62, p < 0.01) in the 656 patients who were alive and not rehospitalized within 1 year. CONCLUSIONS: The presence of a psychiatric comorbidity is a significant predictor of multiple measures of unplanned healthcare utilization in medical ICU survivors with a primary or secondary discharge diagnosis of alcohol withdrawal. This finding highlights the potential importance of targeting longitudinal multidisciplinary care to patients with a dual diagnosis.

INTRODUCTION: Critically ill patients can develop acute respiratory failure requiring endotracheal intubation. Swallowing dysfunction after liberation from mechanical ventilation, also known as post-extubation dysphagia, is common and deleterious among patients without neurologic disease. However, the risk factors associated with the development of post-extubation dysphagia and its effect on hospital lengthofstay in critically ill patients with neurologic disorders remains relatively unexplored. METHODS: We conducted a retrospective, observational cohort study from 2008 to 2010 of patients with neurologic impairment who required mechanical ventilation and subsequently received a bedside swallow evaluation (BSE) by a speech-language pathologist. RESULTS: A BSE was performed after mechanical ventilation in 25% (630/2,484) of all patients. In the 184 patients with neurologic impairment, post-extubation dysphagia was present in 93% (171/184), and was classified as mild, moderate, or severe in 34% (62/184), 26% (48/184), and 33% (61/184), respectively. In univariate analyses, statistically significant risk factors for moderate/severe dysphagia included longer durations of mechanical ventilation and the presence of a tracheostomy. In multivariate analysis, adjusting for age, tracheostomy, cerebrovascular disease, and severity of illness, mechanical ventilation for >7 days remained independently associated with moderate/severe dysphagia (adjusted odds ratio=4.48 (95%confidence interval=2.14 to 9.81), P<0.01). The presence of moderate/severe dysphagia was also significantly associated with prolonged hospital lengthofstay, discharge status, and surgical placement of feeding tubes. When adjusting for age, severity of illness, and tracheostomy, patients with moderate/severe dysphagia stayed in the hospital 4.32 days longer after their initial BSE than patients with none/mild dysphagia (95% confidence interval=3.04 to 5.60 days, P<0.01). CONCLUSION: In a cohort of critically ill patients with neurologic impairment, longer duration of mechanical ventilation is independently associated with post-extubation dysphagia, and the development of post-extubation dysphagia is independently associated with a longer hospital length of stay after the initial BSE.

INTRODUCTION: We sought to determine whether higher levels of the novel biomarker growth differentiation factor-15 (GDF-15) are associated with poor outcomes and the presence of pulmonary vascular dysfunction (PVD) in patients with acute respiratory distress syndrome (ARDS). METHODS: We conducted a retrospective cohort study in patients enrolled in the Acute Respiratory Distress Syndrome Network Fluid and Catheter Treatment (FACT) Trial. Patients enrolled in the FACT Trial who received a pulmonary artery catheter (PAC), had plasma available from the same study day and sufficient hemodynamic data to determine the presence of PVD were included. Logistic regression was used to determine the association between GDF-15 level and 60-day mortality. RESULTS: Of the 513 patients enrolled in the FACT Trial assigned to receive a PAC, 400 were included in this analysis. Mortality at 60 days was significantly higher in patients whose GDF-15 levels were in the third (28%) or fourth (49%) quartile when compared to patients with GDF-15 levels in the first quartile (12%) (P <0.001). Adjusting for severity of illness measured by APACHE III score, the odds of death for patients with GDF-15 levels in the fourth quartile when compared to the first quartile was 4.26 (95% CI 2.18, 10.92, P <0.001). When added to APACHE III alone for prediction of 60-day mortality, GDF-15 levels increased the area under the receiver operating characteristic curve from 0.72 to 0.77. At an optimal cutoff of 8,103 pg/mL, the sensitivity and specificity of GDF-15 for predicting 60-day mortality were 62% (95% CI 53%, 71%) and 76% (95% CI 71%, 81%), respectively. Levels of GDF-15 were not useful in identifying the presence of PVD, as defined by hemodynamic measurements obtained by a PAC. CONCLUSIONS: In patients with ARDS, higher levels of GDF-15 are significantly associated with poor outcome but not PVD.

BACKGROUND: Unhealthy alcohol use predisposes to multiple conditions that frequently result in critical illness and is present in up to one-third of patients admitted to a medical intensive care unit (ICU). We sought to determine the baseline readiness to change in medical ICU patients with unhealthy alcohol use and hypothesized that the severity of acute illness would be independently associated with higher scores on readiness to change scales. We further sought to determine whether this effect is modified by the severity of unhealthy alcohol use. METHODS: We performed a cross-sectional observational study of current regular drinkers in 3 medical ICUs. The Alcohol Use Disorders Identification Test was used to differentiate low-risk and unhealthy alcohol use and further categorize patients into risky alcohol use or an alcohol use disorder. The severity of a patient's acute illness was assessed by calculating the Acute Physiologic and Chronic Health Evaluation II (APACHE II) score at the time of admission to the medical ICU. Readiness to change was assessed using standardized questionnaires. RESULTS: Of 101 medical ICU patients who were enrolled, 65 met the criteria for unhealthy alcohol use. The association between the severity of acute illness and readiness to change depended on the instrument used. A higher severity of illness measured by APACHE II score was an independent predictor of readiness to change as assessed by the Stages of Change Readiness and Treatment Eagerness Scale (Taking Action scale; p < 0.01). When a visual analog scale was used to assess readiness to change, there was a significant association with severity of acute illness (p < 0.01) that was modified by the severity of unhealthy alcohol use (p = 0.04 for interaction term). CONCLUSIONS: Medical ICU patients represent a population where brief interventions require further study. Studies of brief intervention should account for the severity of acute illness and the severity of unhealthy alcohol use as potential effect modifiers.

Background: Discordance with well-known sepsis resuscitation guidelines is often attributed to rational assessments of patients at the point of care. Conversely, we sought to explore the impact of choice architecture (i.e., the environment, manner, and behavioral psychology within which options are presented and decisions are made) on decisions to prescribe guideline-discordant fluid volumes. Design: We conducted an electronic, survey-based study using a septic shock clinical vignette. Physicians from multiple specialties and training levels at an academic tertiary-care hospital and academic safety-net hospital were randomized to distinct answer sets: control (6 fluid options), time constraint (6 fluid options with a 10-s limit to answer), or choice overload (25 fluid options). The primary outcome was discordance with Surviving Sepsis Campaign fluid resuscitation guidelines. We also measured response times and examined the relationship between each choice architecture intervention group, response time, and guideline discordance. Results: A total of 189 of 624 (30.3%) physicians completed the survey. Time spent answering the vignette was reduced in time constraint (9.5 s, interquartile range [IQR] 7.3 s to 10.0 s, P < 0.001) and increased in choice overload (56.8 s, IQR 35.9 s to 86.7 s, P < 0.001) groups compared with control (28.3 s, IQR 20.0 s to 44.6 s). In contrast, the relative risk of guideline discordance was higher in time constraint (2.07, 1.33 to 3.23, P = 0.001) and lower in choice overload (0.75, 0.60, to 0.95, P =0.02) groups. After controlling for time spent reading the vignette, the overall odds of choosing guideline-discordant fluid volumes were reduced for every additional second spent answering the vignette (OR 0.98, 0.97, to 0.99, P < 0.001). Conclusions: Choice architecture may affect fluid resuscitation decisions in sepsis regardless of patient conditions, warranting further investigation in real-world contexts. These effects should be considered when implementing practice guidelines. Highlights: Time constrained clinical decision making was associated with increased proportion of guideline-discordant responses and relative risk of failure to prescribe guideline-recommended intravenous fluids using a sepsis clinical vignette.Choice overload increased response times and was associated with decreased proportion of guideline-discordant responses and relative risk of guideline discordance.Physician odds of choosing to prescribe guideline-discordant fluid volumes were reduced with increased deliberation as measured by response times.Clinicians, researchers, policy makers, and administrators should consider the effect of choice architecture on clinical decision making and guideline discordance when implementing guidelines for sepsis and other acute care conditions.
RESUMO
OBJECTIVES: Cigarette smoking and unhealthy alcohol use are common causes of preventable morbidity and mortality that frequently result in admission to an intensive care unit. Understanding how to identify and intervene in these conditions is important because critical illness may provide a "teachable moment." Furthermore, the Joint Commission recently proposed screening and receipt of an intervention for tobacco use and unhealthy alcohol use as candidate performance measures for all hospitalized patients. Understanding the efficacy of these interventions may help drive evidence-based institution of programs, if deemed appropriate. DATA SOURCES: A summary of the published medical literature on interventions for unhealthy alcohol use and smoking obtained through a PubMed search. SUMMARY: Interventions focusing on behavioral counseling for cigarette smoking in hospitalized patients have been extensively studied. Several studies include or focus on critically ill patients. The evidence demonstrates that behavioral counseling leads to increased rates of smoking cessation but the effect depends on the intensity of the intervention. The identification of unhealthy alcohol use can lead to brief interventions. These interventions are particularly effective in trauma patients with unhealthy alcohol use. However, the current literature would not support routine delivery of brief interventions for unhealthy alcohol use in the medical intensive care unit population. CONCLUSIONS: Intensive care unit admission represents a "teachable moment" for smokers and some patients with unhealthy alcohol use. Future studies should assess the efficacy of brief interventions for unhealthy alcohol use in medical intensive care unit patients. In addition, identification of the timing and optimal individual to conduct the intervention will be necessary.

INTRODUCTION: Dysphagia is common among survivors of critical illness who required mechanical ventilation during treatment. The risk factors associated with the development of postextubation dysphagia, and the effects of dysphagia on patient outcomes, have been relatively unexplored. METHODS: We conducted a retrospective, observational cohort study from 2008 to 2010 of all patients over 17 years of age admitted to a university hospital ICU who required mechanical ventilation and subsequently received a bedside swallow evaluation (BSE) by a speech pathologist. RESULTS: A BSE was performed after mechanical ventilation in 25% (630 of 2,484) of all patients. After we excluded patients with stroke and/or neuromuscular disease, our study sample size was 446 patients. We found that dysphagia was present in 84% of patients (n = 374) and classified dysphagia as absent, mild, moderate or severe in 16% (n = 72), 44% (n = 195), 23% (n = 103) and 17% (n = 76), respectively. In univariate analyses, we found that statistically significant risk factors for severe dysphagia included long duration of mechanical ventilation and reintubation. In multivariate analysis, after adjusting for age, gender and severity of illness, we found that mechanical ventilation for more than seven days remained independently associated with moderate or severe dysphagia (adjusted odds ratio (AOR) = 2.84 [interquartile range (IQR) = 1.78 to 4.56]; P < 0.01). The presence of severe postextubation dysphagia was significantly associated with poor patient outcomes, including pneumonia, reintubation, in-hospital mortality, hospital length of stay, discharge status and surgical placement of feeding tubes. In multivariate analysis, we found that the presence of moderate or severe dysphagia was independently associated with the composite outcome of pneumonia, reintubation and death (AOR = 3.31 [IQR = 1.89 to 5.90]; P < 0.01). CONCLUSIONS: In a large cohort of critically ill patients, long duration of mechanical ventilation was independently associated with postextubation dysphagia, and the development of postextubation dysphagia was independently associated with poor patient outcomes.

OBJECTIVE: Over the past decade, cannabis use has become increasingly popular in states that include Colorado. During this time, alcohol use disorders (AUDs) and alcohol-related medical conditions have also been consistently recognized as public health problems with increasing prevalence in the state. Despite the widespread use of cannabis in Colorado, the epidemiology of cannabis use among those with AUDs has been poorly described. Therefore, we sought to examine cannabis use among individuals with likely AUDs and individuals with low-risk alcohol use during a time of major Colorado legislative changes before and after legalization of recreational cannabis in 2012. METHODS: This study was a secondary data analysis conducted with information from 303 participants (80% male) in the Denver, CO metropolitan enrolled between August 2007 and April 2016 for studies related to alcohol and lung health. Of these participants, 188 (62%) were completing inpatient alcohol detoxification with likely AUDs. All participants completed the Alcohol Use Disorder Identification Test (AUDIT) to establish their likelihood of an AUD, and all had information on current cannabis use assessed by questionnaire and urine toxicology testing. RESULTS: Individuals with likely AUDs more commonly used cannabis compared to control participants (42% vs 27%, p = 0.007). In multiple logistic regression analyses, participant type (likely AUD versus control), tobacco smoking, and age were significantly associated with cannabis smoking; however, the year of participant enrollment was not. Adjusted odds for cannabis use among participants with likely AUDs were 2.97 (1.51-5.82), p = 0.002, while odds for cannabis use among tobacco smokers were 3.67 (1.94-6.93), p < 0.0001. Among control participants, tobacco smoking increased odds of cannabis use seven-fold. CONCLUSIONS: Our findings highlight the exceptionally high odds of cannabis use among individuals with likely AUDs undergoing alcohol detoxification at a Colorado treatment facility before and after legalization of recreational cannabis. Targeted investigations into the medical and psychiatric consequences of combined alcohol and cannabis use are urgently needed to define its health impact in these vulnerable individuals.
RESUMO
Background: Pulmonary and critical care medicine (PCCM) fellowship requires a high degree of medical knowledge and procedural competency. Gaps in fellowship readiness can result in significant trainee anxiety related to starting fellowship training.Objective: To improve fellowship readiness and alleviate anxiety for PCCM-bound trainees by improving confidence in procedural skills and cognitive domains.Methods: Medical educators within the American Thoracic Society developed a national resident boot camp (RBC) to provide an immersive, experiential training program for physicians entering PCCM fellowships. The RBC curriculum is a 2-day course designed to build procedural skills, medical knowledge, and clinical confidence through high-fidelity simulation and active learning methodology. Separate programs for adult and pediatric providers run concurrently to provide unique training objectives targeted to their learners' needs. Trainee assessments include multiple-choice pre- and post-RBC knowledge tests and confidence assessments, which are scored on a four-point Likert scale, for specific PCCM-related procedural and cognitive skills. Learners also evaluate course material and educator effectiveness, which guide modifications of future RBC programs and provide feedback for individual educators, respectively.Results: The American Thoracic Society RBC was implemented in 2014 and has grown annually to include 132 trainees and more than 100 faculty members. Mean knowledge test scores for participants in the 2019 RBC adult program increased from 55% (±14% SD) on the pretest to 72% (±11% SD; P < 0.001) after RBC completion. Similarly, mean pretest scores for pediatric course attendees increased from 54% (±13% SD) to 62% (±19% SD; P = 0.17). Specific content domains that improved by 10% or more between pre- and posttests included airway management, bronchoscopy, pulmonary function testing, and code management for adult course participants, and airway management, pulmonary function testing, and extracorporeal membrane oxygenation for pediatric course participants. Trainee confidence also significantly improved across all procedural and cognitive domains for adult trainees and in 10 of 11 domains for pediatric course attendees. Course content for the 2019 RBC was overwhelmingly rated as "on target" for the level of learner, with <4% of respondents indicating any specific session was "much too basic" or "much too advanced."Conclusion: RBC participation improved PCCM-bound trainee knowledge, procedural familiarity, and confidence. Refinement of the RBC curriculum over the past 7 years has been guided by educator and course evaluations, with the ongoing goal of meeting the evolving educational needs of rising PCCM trainees.
RESUMO
Many survivors of critical illness have problematic alcohol use, associated with risk of death and hospital readmission. We tested the feasibility, acceptability, treatment fidelity, and potential efficacy of a customized alcohol intervention for patients in ICUs. The intervention was delivered by a Recovery Navigator using principles of motivational interviewing and shared decision-making. DESIGN: Pilot randomized trial. SETTING: Two urban ICUs in Denver, CO. PATIENTS: Patients with problematic alcohol use were enrolled prior to hospital discharge. INTERVENTIONS: Patients were randomly assigned to usual care, single-session motivational interviewing and shared decision-making, or multisession motivational interviewing and shared decision-making. MEASUREMENTS AND MAIN RESULTS: We assessed feasibility via enrollment and attrition, acceptability via patient satisfaction (Client Satisfaction Questionnaire-8), fidelity via observation and questionnaires, and potential efficacy via group means and CIs on measures of alcohol use, psychiatric symptoms, cognition, and other alcohol-related problems. Over 18 months, we offered the study to 111 patients, enrolled 47, and randomized 36; refusals were mainly due to stigma or patients' desire to handle problems on their own. Groups were similar at baseline, and 67% of patients met criteria for alcohol use disorder. Average patient satisfaction was high (mean = 28/32) regardless of group assignment. Sessions were delivered with 98% adherence to motivational interviewing principles and excellent motivational interviewing spirit; patients perceived the intervention to be more autonomy supportive than usual care. Group means after 6 months suggested that patients receiving the intervention might improve on measures such as alcohol use, psychiatric symptoms, legal problems, and days of paid work; however, they did not receive more substance use treatment. All results were nonsignificant due to small sample size. CONCLUSIONS: A Recovery Navigator intervention was feasible and acceptable for delivering high-fidelity brief interventions to ICU patients. Changes in alcohol-related problems with motivational interviewing and shared decision-making were nonsignificant but clinically meaningful in size. A full-scale randomized trial of motivational interviewing and shared decision-making is warranted.
