The Impact of Choice Architecture on Sepsis Fluid Resuscitation Decisions: An Exploratory Survey-Based Study.

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.

Research Needs for Inpatient Management of Severe Alcohol Withdrawal Syndrome: An Official American Thoracic Society Research Statement.

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.

The relationship of cannabis decriminalization in Colorado and cannabis use in individuals with alcohol use disorders.

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.

Development of a National Academic Boot Camp to Improve Fellowship Readiness.

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.

Patterns of utilization and effects of hospital-specific factors on physical, occupational, and speech therapy for critically ill patients with acute respiratory failure in the USA: results of a 5-year sample.

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.

Pilot Randomized Trial of a Recovery Navigator Program for Survivors of Critical Illness With Problematic Alcohol Use.

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.

Alcohol misuse and outpatient follow-up after hospital discharge: a retrospective cohort study.

PURPOSE: Patients with alcohol misuse are less likely to receive preventive health services but more likely to utilize emergency health services. However, the association between alcohol misuse and outpatient follow-up after hospitalization is unknown and may depend on whether a patient experiences a critical illness. We sought to determine whether alcohol misuse was associated with lower rates of outpatient follow-up after hospital discharge and whether the magnitude of this association differed in patients who experienced a critical illness. MATERIALS AND METHODS: This was a retrospective cohort study using administrative data from an urban safety net hospital. Patients were included if they were admitted between 2011 and 2015, were between the ages of 18 and 89, resided within the safety net county, were discharged home, and were at moderate to high risk for hospital readmission within the subsequent 30 days. Alcohol misuse was identified using a combination of ICD-9 codes and response to a single screening question. The primary outcome was a combined measure of follow-up with a primary care physician or specialist provider in the 30 days following hospital discharge. Multivariable logistic regression was used to adjust for factors known to be associated with healthcare utilization. RESULTS: Overall, 17,575 patients were included in the analysis; 4984 (28%) had alcohol misuse. In the 30 days following hospital discharge, 46% of patients saw any outpatient provider. In an unadjusted analysis, the association between alcohol misuse and attending any outpatient follow-up was dependent on whether patients had a critical illness (p value < 0.0001) with the highest rates of follow-up in survivors of critical illness without alcohol misuse (53%, 95% CI 51%, 55%) followed by patients without alcohol misuse or critical illness (49%; 95% CI 48%, 50%), patients with alcohol misuse without critical illness (38%; 95% CI 36%, 39%), and patients with alcohol misuse and a critical illness (37%; 95% CI 35%, 40%). Adjusting for factors associated with healthcare utilization, these findings were modestly attenuated but unchanged. CONCLUSIONS: Patients with alcohol misuse who are at moderate to high risk for hospital readmission may benefit from targeted interventions to increase rates of outpatient follow-up after hospital discharge.

Is lack of social support associated with a delay in seeking medical care? A cross-sectional study of Minnesota and Tennessee residents using data from the Behavioral Risk Factor Surveillance System.

OBJECTIVE: Previous studies have demonstrated an association between social support and lower morbidity and mortality. Delay in seeking medical care is associated with poor health outcomes. The relationship between social support and delay in seeking medical care has not been established. We sought to determine whether lack of social support is associated with higher rates of delays in seeking needed medical care. METHODS: This is a cross-sectional observational study using data from the 2013 and 2014 Centers for Disease Control Behavioral Risk Factor Surveillance System. Participants who were asked questions about delays in medical care and social support were included. The primary outcome was a self-reported delay in seeking needed medical care. The primary independent variable of interest was a dichotomised measure of social support. Multivariable logistic regression was performed, adjusting for demographics, socioeconomic status, comorbidities and access to care. RESULTS: Participants without social support were more likely to report delaying needed medical care when compared with participants with social support (38%vs19%, p<0.001). The association between lack of social support and delays in care persisted after adjustment for demographics, socioeconomic status, comorbidities and access to care (OR 1.72; 95% CI 1.45 to 2.06; p<0.001). CONCLUSIONS: Lack of perceived social support is associated with patient-reported delay of needed medical care. This association may contribute to the poor health outcomes experienced by those with a lack of social support.

African Americans Are Less Likely to Receive Care by a Cardiologist During an Intensive Care Unit Admission for Heart Failure.

OBJECTIVES: This study sought to determine whether the likelihood of receiving primary intensive care unit (ICU) care by a cardiologist versus a noncardiologist was greater for Caucasians than for African Americans admitted to an ICU for heart failure (HF). The authors further evaluated whether primary ICU care by a cardiologist is associated with higher in-hospital survival, irrespective of race. BACKGROUND: Increasing data demonstrate an association between better HF outcomes and care by a cardiologist. It is unclear if previously noted racial differences in cardiology care persist in an ICU setting. METHODS: Using the Premier database, adult patients admitted to an ICU with a primary discharge diagnosis of HF from 2010 to 2014 were included. Hierarchical logistic regression models were used to determine the association between race and primary ICU care by a cardiologist, adjusting for patient and hospital variables. Cox regression with inverse probability weighting was used to assess the association between cardiology care and in-hospital mortality. RESULTS: Among 104,835 patients (80.3% Caucasians, 19.7% African Americans), Caucasians had higher odds of care by a cardiologist than African Americans (adjusted odds ratio: 1.42; 95% confidence interval: 1.34 to 1.51). Compared with a noncardiologist, primary ICU care by a cardiologist was associated with higher in-hospital survival (adjusted hazard ratio: 1.20, 95% confidence interval: 1.11 to 1.28). The higher likelihood of survival did not differ by patient race (interaction p = 0.32). CONCLUSIONS: Among patients admitted to an ICU for HF, African Americans were less likely than Caucasians to receive primary care by a cardiologist. Primary care by a cardiologist was associated with higher survival for both Caucasians and African Americans.

Outcomes of ICU Patients With a Discharge Diagnosis of Critical Illness Polyneuromyopathy: A Propensity-Matched Analysis.

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.

Cut-Point Levels of Phosphatidylethanol to Identify Alcohol Misuse in a Mixed Cohort Including Critically Ill Patients.

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.

The Experience of Patients with Alcohol Misuse after Surviving a Critical Illness. A Qualitative Study.

RATIONALE: Alcohol misuse is common in patients admitted to the intensive care unit (ICU), but there is currently no evidence-based approach to address drinking in ICU survivors. OBJECTIVES: We sought to describe the experience of ICU survivors with alcohol misuse during their hospitalization and the 3 months after hospital discharge to inform an alcohol-specific intervention for this unique population. METHODS: We conducted a descriptive qualitative study of ICU survivors from medical ICUs in three separate hospitals with a positive screening result on the Alcohol Use Disorders Identification Test. Semistructured interviews were conducted 3 months after hospital discharge of patients. Patients were also allowed to nominate up to two friends or family members for enrollment to provide additional perspective on the patient's experience. RESULTS: We enrolled 50 patients and 22 of their friends and/or family members. The average APACHE II score was 23, 80% of patients were male, and the average age was 50 years; 70% of patients and 77% of friends/family members completed the semistructured interview 3 months after hospital discharge. We identified three domains that could inform an alcohol-specific intervention, each with multiple themes: motivation with complications (anxiety and depression, critical illness as a catalyst, delirium and cognitive impairment); therapeutic alliance (autonomy, failure and opportunities to build a therapeutic alliance); and the return to the home milieu (lack of screening for depression and anxiety, social network support for drinking, social isolation, social network support for abstinence, lack of available and affordable treatment, and negative experiences with Alcoholics Anonymous). CONCLUSIONS: An alcohol intervention for ICU survivors would account for the context in which patients are making a decision about their drinking and optimize the patient-provider interaction. Contrary to current paradigms that focus on addressing alcohol consumption only during a hospitalization, an intervention for ICU survivors should continue as patients transition from the hospital to home.

The accuracy of the bedside swallowing evaluation for detecting aspiration in survivors of acute respiratory failure.

BACKGROUND: Dysphagia with subsequent aspiration occurs in up to 60% of acute respiratory failure (ARF) survivors. Accurate bedside tests for aspiration can reduce aspiration-related complications while minimizing delay of oral nutrition. In a cohort of ARF survivors, we determined the accuracy of the bedside swallowing evaluation (BSE) and its components for detecting aspiration. METHODS: Patients who were extubated after at least 24hours of mechanical ventilation were eligible for enrollment. Within 3 days of extubation, patients underwent comprehensive BSE including 3-oz water swallowing test (3-WST), followed by a criterion standard test for aspiration, flexible endoscopic evaluation of swallowing (FEES). RESULTS: Forty-five patients were included in the analysis. Median patient age was 55years (interquartile range, 47-65). Median duration of mechanical ventilation was 3.3days (interquartile range 1.8-6.0). Fourteen patients (31%) aspirated on FEES. Physical examination findings on BSE and abnormal swallowing during trials of different consistencies were variably associated with aspiration. Compared with FEES, the 3-WST yielded a sensitivity of 77% (95% confidence interval [CI], 50%-92%), specificity of 65% (95% CI, 47%-79%), and an area under the receiver operating characteristic curve (AUC) of 0.71; a speech language pathologist's recommendation for altered diet yielded a sensitivity of 86% (95% CI, 60%-96%), a specificity of 52% (95% CI, 35%-68%), and an AUCof 0.69; an speech language pathologist's recommendation for nil per os (nothing by mouth) yielded a sensitivity of 50% (95% CI, 27%-73%), a specificity of 94% (95% CI, 79%-98%), and an AUCof 0.72. CONCLUSIONS: The BSE and its components, including the 3-WST, demonstrated variable accuracy for aspiration in survivors of ARF. Investigation to determine the optimal noninvasive test for aspiration in ARF survivors is warranted.

Alcohol screening scores and the risk of intensive care unit admission and hospital readmission.

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.

Unhealthy alcohol use in older adults: Association with readmissions and emergency department use in the 30 days after hospital discharge.

BACKGROUND: Unhealthy alcohol use could impair recovery of older patients after medical or surgical hospitalizations. However, no prior research has evaluated whether older patients who screen positive for unhealthy alcohol use are at increased risk of readmissions or emergency department (ED) visits within 30 days after discharge. This study examined the association between AUDIT-C alcohol screening results and 30-day readmissions or ED visits. METHODS: Veterans Affairs (VA) patients age 65 years or older, were eligible if they were hospitalized for a medical or surgical condition (2/1/2009-10/1/2011) and had an AUDIT-C score documented in their VA electronic medical record in the year before they were hospitalized. VA and Medicare data identified VA or non-VA index hospitalizations, readmissions, and ED visits. Primary analyses adjusted for demographics, comorbid conditions, and past-year health care utilization. RESULTS: Among 579,330 hospitalized patients, 13.7% were readmitted and 12.0% visited an ED within 30 days of discharge. In primary analyses, high-risk drinking (n=7,167) and nondrinking (n=357,086) were associated with increased probability of readmission (13.8%, 95% CI 13.0-14.6%; and 14.2%, 95% CI 14.1-14.3%, respectively), relative to low-risk drinking (12.9%; 95% CI 12.7-13.0%). Only nondrinkers had increased risk for ED visits. CONCLUSIONS: Alcohol screening results indicating high-risk drinking that were available in medical records were modestly associated with risk for 30-day readmissions and were not associated with risk for ED visits.

Brief Versus Full Alcohol Use Disorders Identification Test in National Heart, Lung, and Blood Institute Acute Respiratory Distress Syndrome Network Clinical Trials.

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.

Predictors of severe alcohol withdrawal syndrome: a systematic review and meta-analysis.

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.

Facilitators and barriers to initiating change in medical intensive care unit survivors with alcohol use disorders: a qualitative study.

PURPOSE: Alcohol abuse and dependence are collectively referred to as alcohol use disorders (AUD). An AUD is present in up to one third of patients admitted to an intensive care unit (ICU). We sought to understand the barriers and facilitators to change in ICU survivors with an AUD to provide a foundation upon which to tailor alcohol-related interventions. METHODS: We used a qualitative approach with a broad constructivist framework, conducting semistructured interviews in medical ICU survivors with an AUD. Patients were included if they were admitted to 1 of 2 medical ICUs and were excluded if they refused participation, were unable to participate, or did not speak English. Digitally recorded and professionally transcribed interviews were analyzed using a general inductive approach and grouped into themes. RESULTS: Nineteen patients were included, with an average age of 51 (interquartile range, 36-51) years and an average Acute Physiology and Chronic Health Evaluation II score of 9 (interquartile range, 5-13); 68% were white, 74% were male, and the most common reason for admission was alcohol withdrawal (n=8). We identified 5 facilitators of change: empathy of the inpatient health care environment, recognition of accumulating problems, religion, pressure from others to stop drinking, and trigger events. We identified 3 barriers to change: missed opportunities, psychiatric comorbidity, and cognitive dysfunction. Social networks were identified as either a barrier or facilitator to change depending on the specific context. CONCLUSIONS: Alcohol-related interventions to motivate and sustain behavior change could be tailored to ICU survivors by accounting for unique barriers and facilitators.
