Patient and Caregiver-Derived Health Service Improvements for Better Critical Care Recovery.

OBJECTIVES: To engage critical care end-users (survivors and caregivers) to describe their emotions and experiences across their recovery trajectory, and elicit their ideas and solutions for health service improvements to improve the ICU recovery experience. DESIGN: End-user engagement as part of a qualitative design using the Framework Analysis method. SETTING: The Society of Critical Care Medicine's THRIVE international collaborative sites (follow-up clinics and peer support groups). SUBJECTS: Patients and caregivers following critical illness and identified through the collaboratives. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Eighty-six interviews were conducted. The following themes were identified: 1) Emotions and experiences of patients-"Loss of former self; Experiences of disability and adaptation"; 2) Emotions and experiences of caregivers-"Emotional impacts, adopting new roles, and caregiver burden; Influence of gender roles; Adaptation, adjustment, recalibration"; and 3) Patient and caregiver-generated solutions to improve recovery across the arc of care-"Family-targeted education; Expectation management; Rehabilitation for patients and caregivers; Peer support groups; Reconnecting with ICU post-discharge; Access to community-based supports post-discharge; Psychological support; Education of issues of ICU survivorship for health professionals; Support across recovery trajectory." Themes were mapped to a previously published recovery framework (Timing It Right) that captures patient and caregiver experiences and their support needs across the phases of care from the event/diagnosis to adaptation post-discharge home. CONCLUSIONS: Patients and caregivers reported a range of emotions and experiences across the recovery trajectory from ICU to home. Through end-user engagement strategies many potential solutions were identified that could be implemented by health services and tested to support the delivery of higher-quality care for ICU survivors and their caregivers that extend from tertiary to primary care settings.

Modification of social determinants of health by critical illness and consequences of that modification for recovery: an international qualitative study.

OBJECTIVES: Social determinants of health (SDoH) contribute to health outcomes. We identified SDoH that were modified by critical illness, and the effect of such modifications on recovery from critical illness. DESIGN: In-depth semistructured interviews following hospital discharge. Interview transcripts were mapped against a pre-existing social policy framework: money and work; skills and education; housing, transport and neighbourhoods; and family, friends and social connections. SETTING: 14 hospital sites in the USA, UK and Australia. PARTICIPANTS: Patients and caregivers, who had been admitted to critical care from three continents. RESULTS: 86 interviews were analysed (66 patients and 20 caregivers). SDoH, both financial and non-financial in nature, could be negatively influenced by exposure to critical illness, with a direct impact on health-related outcomes at an individual level. Financial modifications included changes to employment status due to critical illness-related disability, alongside changes to income and insurance status. Negative health impacts included the inability to access essential healthcare and an increase in mental health problems. CONCLUSIONS: Critical illness appears to modify SDoH for survivors and their family members, potentially impacting recovery and health. Our findings suggest that increased attention to issues such as one's social network, economic security and access to healthcare is required following discharge from critical care.

Assessment and Impact of Intravenous Medication Fluid Administration in Critically Ill Patients With Acute Respiratory Failure.

BACKGROUND: Positive fluid balance early in critical illness is associated with poor outcomes. Reducing intravenous medication volume may mitigate volume overload. Objective: Assessment of fluid and medication administration and clinical outcomes in acute respiratory failure. METHODS: Single-center, prospective observational study of hemodynamically stable adult patients in a medical intensive care unit (MICU) with acute respiratory failure. RESULTS: Median cumulative total intake volume was 12 890 (interquartile range [IQR] = 8654-22 221) mL (n = 27), and median cumulative intravenous medication volume was 3563 (IQR = 2371-9412) mL over the first 7 days. Medication volume accounted for 27.6% of aggregate fluid volume. Median daily intravenous medication volume administered was 591 (IQR = 339-1082) mL. Cumulative fluid volume was associated with reduced ventilator-free days (r2 = -0.393; P = 0.043), and cumulative fluid volumes during the first 3 and 7 days were associated with increased MICU length of stay (LOS ± standard error 0.73 ± 0.35 d/L, P = 0.047, and 0.38 ± 0.16 d/L, P = 0.021, respectively). Cumulative medication volume administered significantly reduced the likelihood of mechanical ventilator liberation (hazard ratio [HR] = 0.917; 95% CI: 0.854, 0.984; P = 0.016) and MICU discharge (HR = 0.911; 95% CI: 0.843, 0.985; P = 0.019). Small-volume infusion may decrease cumulative intravenous medication volume by 38%. CONCLUSION AND RELEVANCE: Intravenous medication diluent contributes substantially to total fluid intake in patients with acute respiratory failure and is associated with poor outcomes. Reduction of intravenous medication fluid volume to improve clinical outcomes should be further investigated.

Optimizing Critical Illness Recovery: Perspectives and Solutions From the Caregivers of ICU Survivors.

OBJECTIVES: To understand the unmet needs of caregivers of ICU survivors, how they accessed support post ICU, and the key components of beneficial ICU recovery support systems as identified from a caregiver perspective. DESIGN: International, qualitative study. SUBJECTS: We conducted 20 semistructured interviews with a diverse group of caregivers in the United States, the United Kingdom, and Australia, 11 of whom had interacted with an ICU recovery program. SETTING: Seven hospitals in the United States, United Kingdom, and Australia. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Content analysis was used to explore prevalent themes related to unmet needs, as well as perceived strategies to improve ICU outcomes. Post-ICU care was perceived to be generally inadequate. Desired caregiver support fell into two main categories: practical support and emotional support. Successful care delivery initiatives included structured programs, such as post discharge telephone calls, home health programs, post-ICU clinics, and peer support groups, and standing information resources, such as written educational materials and online resources. CONCLUSIONS: This qualitative, multicenter, international study of caregivers of critical illness survivors identified consistently unmet needs, means by which caregivers accessed support post ICU, and several care mechanisms identified by caregivers as supporting optimal ICU recovery.

Transitions of Care After Critical Illness-Challenges to Recovery and Adaptive Problem Solving.

OBJECTIVES: Investigate the challenges experienced by survivors of critical illness and their caregivers across the transitions of care from intensive care to community, and the potential problem-solving strategies used to navigate these challenges. DESIGN: Qualitative design-data generation via interviews and data analysis via the framework analysis method. SETTING: Patients and caregivers from three continents, identified through the Society of Critical Care Medicine's THRIVE international collaborative sites (follow-up clinics and peer support groups). SUBJECTS: Patients and caregivers following critical illness. INTERVENTIONS: Nil. MEASUREMENTS AND MAIN RESULTS: From 86 interviews (66 patients, 20 caregivers), we identified the following major themes: 1) Challenges for patients-interacting with the health system and gaps in care; managing others' expectations of illness and recovery. 2) Challenges for caregivers-health system shortfalls and inadequate communication; lack of support for caregivers. 3) Patient and caregiver-driven problem solving across the transitions of care-personal attributes, resources, and initiative; receiving support and helping others; and acceptance. CONCLUSIONS: Survivors and caregivers experienced a range of challenges across the transitions of care. There were distinct and contrasting themes related to the caregiver experience. Survivors and caregivers used comparable problem-solving strategies to navigate the challenges encountered across the transitions of care.

Benefits of Peer Support for Intensive Care Unit Survivors: Sharing Experiences, Care Debriefing, and Altruism.

BACKGROUND: After critical illness, patients are often left with impairments in physical, social, emotional, and cognitive functioning. Peer support interventions have been implemented internationally to ameliorate these issues. OBJECTIVE: To explore what patients believed to be the key mechanisms of effectiveness of peer support programs implemented during critical care recovery. METHODS: In a secondary analysis of an international qualitative data set, 66 telephone interviews with patients were undertaken across 14 sites in Australia, the United Kingdom, and the United States to understand the effect of peer support during recovery from critical illness. Prevalent themes were documented with framework analysis. RESULTS: Most patients who had been involved in peer support programs reported benefit. Patients described 3 primary mechanisms: (1) sharing experiences, (2) care debriefing, and (3) altruism. CONCLUSION: Peer support is a relatively simple intervention that could be implemented to support patients during recovery from critical illness. However, more research is required into how these programs can be implemented in a safe and sustainable way in clinical practice.

Society of Critical Care Medicine's International Consensus Conference on Prediction and Identification of Long-Term Impairments After Critical Illness.

BACKGROUND: After critical illness, new or worsening impairments in physical, cognitive, and/or mental health function are common among patients who have survived. Who should be screened for long-term impairments, what tools to use, and when remain unclear. OBJECTIVES: Provide pragmatic recommendations to clinicians caring for adult survivors of critical illness related to screening for postdischarge impairments. PARTICIPANTS: Thirty-one international experts in risk-stratification and assessment of survivors of critical illness, including practitioners involved in the Society of Critical Care Medicine's Thrive Post-ICU Collaboratives, survivors of critical illness, and clinical researchers. DESIGN: Society of Critical Care Medicine consensus conference on post-intensive care syndrome prediction and assessment, held in Dallas, in May 2019. A systematic search of PubMed and the Cochrane Library was conducted in 2018 and updated in 2019 to complete an original systematic review and to identify pre-existing systematic reviews. MEETING OUTCOMES: We concluded that existing tools are insufficient to reliably predict post-intensive care syndrome. We identified factors before (e.g., frailty, preexisting functional impairments), during (e.g., duration of delirium, sepsis, acute respiratory distress syndrome), and after (e.g., early symptoms of anxiety, depression, or post-traumatic stress disorder) critical illness that can be used to identify patients at high-risk for cognitive, mental health, and physical impairments after critical illness in whom screening is recommended. We recommend serial assessments, beginning within 2-4 weeks of hospital discharge, using the following screening tools: Montreal Cognitive Assessment test; Hospital Anxiety and Depression Scale; Impact of Event Scale-Revised (post-traumatic stress disorder); 6-minute walk; and/or the EuroQol-5D-5L, a health-related quality of life measure (physical function). CONCLUSIONS: Beginning with an assessment of a patient's pre-ICU functional abilities at ICU admission, clinicians have a care coordination strategy to identify and manage impairments across the continuum. As hospital discharge approaches, clinicians should use brief, standardized assessments and compare these results to patient's pre-ICU functional abilities ("functional reconciliation"). We recommend serial assessments for post-intensive care syndrome-related problems continue within 2-4 weeks of hospital discharge, be prioritized among high-risk patients, using the identified screening tools to prompt referrals for services and/or more detailed assessments.

Key Components of ICU Recovery Programs: What Did Patients Report Provided Benefit?

To understand from the perspective of patients who did, and did not attend ICU recovery programs, what were the most important components of successful programs and how should they be organized. DESIGN: International, qualitative study. SETTING: Fourteen hospitals in the United States, United Kingdom, and Australia. PATIENTS: We conducted 66 semi-structured interviews with a diverse group of patients, 52 of whom had used an ICU recovery program and 14 whom had not. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Using content analysis, prevalent themes were documented to understand what improved their outcomes. Contrasting quotes from patients who had not received certain aspects of care were used to identify perceived differential effectiveness. Successful ICU recovery programs had five key components: 1) Continuity of care; 2) Improving symptom status; 3) Normalization and expectation management; 4) Internal and external validation of progress; and 5) Reducing feelings of guilt and helplessness. The delivery of care which achieved these goals was facilitated by early involvement (even before hospital discharge), direct involvement of ICU staff, and a focus on integration across traditional disease, symptom, and social welfare needs. CONCLUSIONS: In this multicenter study, conducted across three continents, patients identified specific and reproducible modes of benefit derived from ICU recovery programs, which could be the target of future intervention refinement.

Financial impact of an analgosedation protocol for mechanically ventilated patients in a cardiovascular intensive care unit.

PURPOSE: The primary objective was to evaluate the impact of an analgosedation protocol in a cardiac intensive care unit (CICU) on daily doses and costs of analgesic, sedative, and antipsychotic medications. METHODS: We conducted a single-center quasi-experimental study in 363 mechanically ventilated patients admitted to our CICU from March 1, 2011, to April 13, 2013. On March 1, 2012, an analgosedation protocol was implemented. Patients in the pre-implementation group were managed at the cardiologist's discretion, which consisted of a continuous sedative-hypnotic approach and opioids as needed. Patients in the implementation group were managed using this protocol. RESULTS: The mean ± S.D. per-patient doses (mg/day) of propofol, lorazepam, and clonazepam decreased with the use of an analgosedation protocol (propofol 132,265.7 ± 12,951 versus 87,980.5 ± 10,564 [p = 0.03]; lorazepam 10.5 ± 7.3 versus 3.3 ± 4.0 [p < 0.001]; clonazepam 9.9 ± 8.3 versus 1.1 ± 0.5 [p = 0.03]). The mean daily cost of propofol and lorazepam also significantly decreased (33.5% reduction in propofol cost [p = 0.03]; 69.0% reduction in lorazepam cost [p < 0.001]). The per-patient dose and cost of fentanyl (mcg/day) declined with analgosedation protocol use (fentanyl 2,274.2 ± 2317.4 versus 1,026.7 ± 981.4 [p < 0.001]; 54.8% decrease in fentanyl cost [p < 0.001]). CONCLUSION: The implementation of an analgosedation protocol significantly decreased both the use and cost of propofol, lorazepam, and fentanyl. Further investigation of the clinical impact and cost-effectiveness of a critical care consultation service with implementation of an analgosedation protocol is warranted in the CICU.

Family-Centered Care in the Intensive CareUnit-What Does Best Practice Tell Us?

Families in the intensive care unit (ICU) experience high-stress levels and are at risk of developing psychological symptoms including depression, anxiety, and posttraumatic stress disorder (PTSD). Family-centered care defines an approach that encompasses respect, compassion, and support for families. By alleviating stress and anxiety, this approach can increase family satisfaction, improve communication with staff, and decrease ICU length of stay. Family-centered care relies on an interdisciplinary approach. Its components include daily family-centered rounds, frequent family meetings, and ensuring an adequate family support environment. Each of the components of family-centered care depend on adequately trained clinical staff who are champion in empathetic communication and constantly support family member throughout an ICU stay.

Key mechanisms by which post-ICU activities can improve in-ICU care: results of the international THRIVE collaboratives.

OBJECTIVE: To identify the key mechanisms that clinicians perceive improve care in the intensive care unit (ICU), as a result of their involvement in post-ICU programs. METHODS: Qualitative inquiry via focus groups and interviews with members of the Society of Critical Care Medicine's THRIVE collaborative sites (follow-up clinics and peer support). Framework analysis was used to synthesize and interpret the data. RESULTS: Five key mechanisms were identified as drivers of improvement back into the ICU: (1) identifying otherwise unseen targets for ICU quality improvement or education programs-new ideas for quality improvement were generated and greater attention paid to detail in clinical care. (2) Creating a new role for survivors in the ICU-former patients and family members adopted an advocacy or peer volunteer role. (3) Inviting critical care providers to the post-ICU program to educate, sensitize, and motivate them-clinician peers and trainees were invited to attend as a helpful learning strategy to gain insights into post-ICU care requirements. (4) Changing clinician's own understanding of patient experience-there appeared to be a direct individual benefit from working in post-ICU programs. (5) Improving morale and meaningfulness of ICU work-this was achieved by closing the feedback loop to ICU clinicians regarding patient and family outcomes. CONCLUSIONS: The follow-up of patients and families in post-ICU care settings is perceived to improve care within the ICU via five key mechanisms. Further research is required in this novel area.

Enablers and Barriers to Implementing ICU Follow-Up Clinics and Peer Support Groups Following Critical Illness: The Thrive Collaboratives.

OBJECTIVES: Data are lacking regarding implementation of novel strategies such as follow-up clinics and peer support groups, to reduce the burden of postintensive care syndrome. We sought to discover enablers that helped hospital-based clinicians establish post-ICU clinics and peer support programs, and identify barriers that challenged them. DESIGN: Qualitative inquiry. The Consolidated Framework for Implementation Research was used to organize and analyze data. SETTING: Two learning collaboratives (ICU follow-up clinics and peer support groups), representing 21 sites, across three continents. SUBJECTS: Clinicians from 21 sites. MEASUREMENT AND MAIN RESULTS: Ten enablers and nine barriers to implementation of "ICU follow-up clinics" were described. A key enabler to generate support for clinics was providing insight into the human experience of survivorship, to obtain interest from hospital administrators. Significant barriers included patient and family lack of access to clinics and clinic funding. Nine enablers and five barriers to the implementation of "peer support groups" were identified. Key enablers included developing infrastructure to support successful operationalization of this complex intervention, flexibility about when peer support should be offered, belonging to the international learning collaborative. Significant barriers related to limited attendance by patients and families due to challenges in creating awareness, and uncertainty about who might be appropriate to attend and target in advertising. CONCLUSIONS: Several enablers and barriers to implementing ICU follow-up clinics and peer support groups should be taken into account and leveraged to improve ICU recovery. Among the most important enablers are motivated clinician leaders who persist to find a path forward despite obstacles.

Outcomes in Burn-Injured Patients Who Develop Sepsis.

This study examines health outcomes in burn patients with sepsis. We hypothesized that burn patients with sepsis would have an increased odds risk for in-hospital death and longer intensive care unit (ICU) stays. This was a retrospective cohort of consecutive patients admitted to the burn ICU with total BSA (TBSA) ≥10% and/or inhalation injury between January 2008 and March 2015. Overall 407 burn patients were included; the case-rate for sepsis was 39.1% (n = 159); 20.1% (n = 82) patients were septic and 18.9% (n = 77) patients experienced septic shock. Patients with septic shock had the highest mortality rate (13.31% no sepsis vs 3.7% sepsis vs 49.4% septic shock, P < .01). Median 28-day ICU-free days was higher in patients without sepsis (23 days [Interquartile range (IQR) 14-27] no sepsis vs 0 days [IQR 0-10] sepsis vs 0 days [IQR 0-0] septic shock, P < .01). Sepsis (with or without shock) increased odds of in-hospital death (odds ratio 7.04, 95% confidence interval 1.93-25.7) in reference to the no sepsis group. With each incremental Sequential Organ Failure Assessment (SOFA) score or 10% TBSA increase, the odds risk for in-hospital death increased by 56 and 75%, respectively. Our study characterized outcomes in patients with sepsis after severe burn injury. The odds risk for in-hospital death was greater in patients with sepsis, increasing burn severity according to TBSA and SOFA score.

Injury Characteristics and von Willebrand Factor for the Prediction of Acute Respiratory Distress Syndrome in Patients With Burn Injury: Development and Internal Validation.

OBJECTIVE: To derive and validate a prediction model for the development of ARDS in burn-injured patients. SUMMARY BACKGROUND DATA: Burn injury carries the highest incidence of acute respiratory distress syndrome (ARDS) among all predisposing conditions, but few studies exist on risk factors in these patients. Studies employing biomarkers and clinical risk factors for predicting ARDS mortality have recently been examined but none exist for onset of ARDS nor in patients with burn injury. METHODS: This was a prospective multicenter study of 113 patients with isolated burn injury or inhalation injury. Clinical variables and plasma biomarkers representative of endothelial injury, epithelial injury, or inflammation were collected within 24 hours of admission. The most parsimonious model was chosen by considering discrimination, calibration, and model fit. RESULTS: Among the biomarkers measured in patients with burn injuries, a one-standard deviation increase in log-transformed levels of the A2 domain of von Willebrand factor in the first 24 hours was most strongly associated with the development of ARDS (OR 7.72; 95% CI: 1.64-36.28, P = 0.03). Of candidate models, a 3-variable model with %TBSA, inhalation injury, and von Willebrand factor-A2 had comparable discrimination to more complex models (area under the curve: 0.90; 95% CI 0.85-0.96). The 3-variable model had good model fit by Hosmer-Lemeshow test (P = 0.74) and maintained similar discrimination after accounting for performance optimism (Bootstrapped area under the curve: 0.90; 95% CI: 0.84-0.95). CONCLUSIONS: The 3-variable model with %TBSA, inhalation injury, and von Willebrand factor could be used to better identify at-risk patients for both the study and prevention of ARDS in patients with burn injury.

Seeing the Patient and Family Through: Nurses and Physicians Experiences With Withdrawal of Life-Sustaining Therapy in the ICU.

Withdrawal of life-sustaining therapy at the end of life is a complex phenomenon. Intensive care nurses and physicians are faced with caring for patients and supporting families, as these difficult decisions are made. The purpose of this study was to explore and describe the experience of critical care nurses and physicians participating in the process of withdrawal of life-sustaining therapy. A hermeneutic phenomenological approach was used to guide this qualitative investigation. Interviews were conducted with critical care nurses and physicians from 2 medical centers. An inductive approach to data analysis was used to understand similarities between the nurses and the physicians' experiences. Methodological rigor was established, and data saturation was achieved. The main categories that were inductively derived from the data analysis included from novice to expert, ensuring ethical care, uncertainty to certainty, facilitating the process, and preparing and supporting families. The categories aided in understanding the experiences of nurses and physicians, as they worked individually and together to see patients and families through the entire illness experience, withdrawal of life-sustaining therapy decision-making process and dying process. Understanding the perspectives of health-care providers involved in the withdrawal of life-sustaining therapy process will help other health-care providers who are striving to provide quality care to the dying and to their families.

Cardiologist perceptions of family-centred rounds in cardiovascular clinical care.

Objective: Few data exist regarding physician attitudes and implementation of family-centred rounds (FCR) in cardiovascular care. This study aimed to assess knowledge and attitudes among cardiologists and cardiology fellows regarding barriers and benefits of FCRs. Methods: An electronic, web-based questionnaire was nationally distributed to cardiology fellows and attending cardiologists. Results: In total, 118 subjects were surveyed, comprising cardiologists (n=64, 54%) and cardiology fellows (n=54, 46%). Overall, 61% of providers reported participating in FCRs and 64% felt family participation on rounds benefits the patient. Both fellows and cardiologists agreed that family rounds eased family anxiety (fellows, 63%; cardiologists, 56%; p=0.53), improved communication between the medical team and the patient and family (fellows, 78%; cardiologists, 61%; p=0.18) and improved patient safety (fellows, 59%; cardiologists, 47%; p=0.43). Attitudes regarding enhancement of trainee education were similar (fellows, 69%; cardiologists, 55%; p=0.19). Fellows and cardiologists felt that family increased the duration of rounds (fellows, 78%; cardiologists, 80%; p=0.18) and led to less efficient rounds (fellows, 54%; cardiologists, 58%; p=0.27). Conclusion: The majority of cardiologists and fellows believed that FCRs benefited families, communication and patient safety, but led to reduced efficiency and longer duration of rounds.

Anticipatory grief and impaired problem solving among surrogate decision makers of critically ill patients: A cross-sectional study.

OBJECTIVES: Anticipatory grief, the experience of grief before the death of a mourned individual, is common among people with seriously ill loved ones and associated with impaired social problem solving. We sought to evaluate anticipatory grief in the Intensive Care Unit setting. RESEARCH METHODOLOGY/DESIGN: Cross-sectional study of surrogate decision-makers of patients admitted to an intensive care unit, incorporating survey methodology. SETTING: Intensive care units at a tertiary care centre. MAIN OUTCOME MEASURES: Surrogates completed a 78-question, self-administered questionnaire consisting of demographic and clinical data, as well as three validated instruments: Anticipatory Grief Scale (AGS), Hospital Anxiety and Depression Scale (HADS), and Social Problem Solving Inventory Revised Short Form (SPSI-R:S). MAIN RESULTS: Surveys were completed by 50 surrogate decision-makers, among whom anticipatory grief was elevated and associated with anxiety and depression. Anticipatory grief was also significantly associated with worsened overall problem solving (Spearman's Rho -0.32, p value 0.02). Surrogates with loved ones who were older or admitted to a trauma unit experienced anticipatory grief at lower levels. Prior admission and Charlson Comorbidity Index scores were not associated with anticipatory grief. CONCLUSION: Levels of anticipatory grief in the intensive care unit are high and associated with concurrent anxiety and depression. Association of anticipatory grief with worsened social problem solving may worsen decision making ability in surrogates.

Effects of binge alcohol consumption on sleep and inflammation in healthy volunteers.

Objective Alcohol is a hypnotic that modifies immune function, specifically the cytokines interferon gamma (IFN-γ) and interleukin 2 (IL-2). We evaluated the association between unscheduled napping and acute alcohol-induced augmentation of IFN-γ and IL-2 expression. Methods In this prospective, observational pilot study, volunteers completed questionnaires on sleep quality, alcohol use, and hangover characteristics. Actigraph recordings began three nights before and continued for four nights after study initiation. Napping was recorded by actigraphy and self-reporting. A weight-based dose of 100-proof vodka was consumed, and the blood alcohol content (BAC) and phytohemagglutinin-M stimulated cytokine level were measured before and 20 minutes, 2 hours, and 5 hours after binge consumption. Results Ten healthy volunteers participated (mean age, 34.4 ± 2.3 years; mean body mass index, 23.9 ± 4.6 kg/m2; 60% female). The mean 20-minute BAC was 137.7 ± 40.7 mg/dL. Seven participants took an unscheduled nap. The ex vivo IFN-γ and IL-2 levels significantly increased at all time points after binge consumption in the nappers, but not in the non-nappers. Conclusion Augmented IFN-γ and IL-2 levels are associated with unscheduled napping after binge alcohol consumption. Further studies are needed to clarify the associations among alcohol consumption, sleep disruption, and inflammatory mediators.
