Guidelines for Family-Centered Care in the Neonatal, Pediatric, and Adult ICU.

Objective: To provide clinicians with evidence-based strategies to optimize the support of the family of critically ill patients in the ICU. Methods: We used the Council of Medical Specialty Societies principles for the development of clinical guidelines as the framework for guideline development. We assembled an international multidisciplinary team of 29 members with expertise in guideline development, evidence analysis, and family-centered care to revise the 2007 Clinical Practice Guidelines for support of the family in the patient-centered ICU. We conducted a scoping review of qualitative research that explored family-centered care in the ICU. Thematic analyses were conducted to support Population, Intervention, Comparison, Outcome question development. Patients and families validated the importance of interventions and outcomes. We then conducted a systematic review using the Grading of Recommendations, Assessment, Development and Evaluations methodology to make recommendations for practice. Recommendations were subjected to electronic voting with pre-established voting thresholds. No industry funding was associated with the guideline development. Results: The scoping review yielded 683 qualitative studies; 228 were used for thematic analysis and Population, Intervention, Comparison, Outcome question development. The systematic review search yielded 4,158 reports after deduplication and 76 additional studies were added from alerts and hand searches; 238 studies met inclusion criteria. We made 23 recommendations from moderate, low, and very low level of evidence on the topics of: communication with family members, family presence, family support, consultations and ICU team members, and operational and environmental issues. We provide recommendations for future research and work-tools to support translation of the recommendations into practice. Conclusions: These guidelines identify the evidence base for best practices for family-centered care in the ICU. All recommendations were weak, highlighting the relative nascency of this field of research and the importance of future research to identify the most effective interventions to improve this important aspect of ICU care.

The burdens of survivorship: an approach to thinking about long-term outcomes after critical illness.

Internationally accepted approaches to the study of functioning and disability can inform critical care practitioners and scholars in their study of functional limitations, disability, and quality of life after critical illness and intensive care. Therefore this article provides an introduction to the World Health Organizations International Classification of Functioning, Disability and Health (ICF). The Institute of Medicine has also recommended this approach for the study of disability. This conceptual framework divides potential problems as follows: problems in body structure and tissue, limitations in activity (i.e., functional limitations as assessed in standardized environments), and restrictions in participation (i.e., the inability to fulfill a social role). The ICF draws attention to effect modifiers that can prevent problems at one level from progressing (or conversely can hasten their progression) to profound decrements in a patients quality of life. It is particularly relevant for studies of long-term outcomes after critical illness and post-intensive care syndrome (PICS). This article provides a discussion of the ICF specific to the intensive care unit and the disablement process, with particular attention to new opportunities for intervention and their implications for cost and quality of life.

Recognizing, Naming, and Measuring a Family Intensive Care Unit Syndrome

Most major decisions in the intensive care unit (ICU) regarding goals of care are shared by clinicians and someone other than the patient. Multicenter clinical trials focusing on improved communication between clinicians and these surrogate decision makers have not reported consistently improved outcomes. We suggest that acquired maladaptive reasoning may contribute importantly to failure of the intervention strategies tested to date. Surrogate decision makers often suffer significant psychological morbidity in the form of stress, anxiety, depression, and post-traumatic stress disorder. Family members in the ICU also suffer cognitive blunting and sleep deprivation. Their decision-making abilities are eroded by anticipatory grief and cognitive biases, while personal and family conflicts further impact their decision making. We propose recognizing a family ICU syndrome to describe the morbidity and associated decision-making impairment experienced by many family members of patients with acute critical illness (in the ICU) and chronic critical illness (in the long-term, acute care hospital). Research rigorously using models of compromised decision making may help elucidate both mechanisms of impairment and targets for intervention. Better quantifying compromised decision making and its relationship to poor outcomes will allow us to formulate and advance useful techniques. The use of decision aids and improving ICU design may provide benefit now and in the near future. In measuring interventions targeting cognitive barriers, clinically significant outcomes, such as time to decision, should be considered. Statistical approaches, such as survival models and rank statistic testing, will increase our power to detect differences in our interventions.

Coronary Artery Disease Is Under-diagnosed and Under-treated in Advanced Lung Disease

BACKGROUND Coronary artery disease is a potentially treatable comorbidity observed frequently in both chronic obstructive pulmonary disease and interstitial lung disease. The prevalence of angiographically proven coronary artery disease in advanced lung disease is not well described. We sought to characterize the treatment patterns of coronary artery disease complicating advanced lung disease and to describe the frequency of occult coronary artery disease in this population. METHODS We performed a 2-center, retrospective cross-sectional study of patients with either chronic obstructive pulmonary disease or interstitial lung disease evaluated for lung transplantation. Medications and diagnoses before the transplant evaluation were recorded in conjunction with left heart catheterization results. RESULTS Of 473 subjects, 351 had chronic obstructive pulmonary disease, and 122 had interstitial lung disease. In subjects diagnosed clinically with coronary artery disease, medical regimens included a statin in 78%, antiplatelet therapy in 62%, angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in 42%, and a beta-blocker in 37%. Ten percent were on no medication from these 4 classes. Fifty-seven percent of these subjects were on an antiplatelet agent as well as a statin, and 13% were on neither. Beta-blockers were less frequently prescribed in chronic obstructive pulmonary disease than interstitial lung disease (23% vs 58%, P=.007). Coronary angiography was available in 322 subjects. It demonstrated coronary artery disease in 60% of subjects, and severe coronary artery disease in 16%. Occult coronary artery disease and severe occult coronary artery disease were found in 53% and 9%, respectively. There were no significant differences in angiographic results between chronic obstructive pulmonary disease and interstitial lung disease, despite imbalanced risk factors. CONCLUSIONS Coronary artery disease is common in patients with advanced lung disease attributable to chronic obstructive pulmonary disease or interstitial lung disease and is under-diagnosed. Guideline-recommended cardioprotective medications are suboptimally utilized in this population.

Learned helplessness among families and surrogate decision-makers of patients admitted to medical, surgical, and trauma ICUs

BACKGROUND We sought to determine the prevalence of and clinical variables associated with learned helplessness, a psychologic state characterized by reduced motivation, difficulty in determining causality, and depression, in family members of patients admitted to ICUs. METHODS We conducted an observational survey study of a prospectively defined cohort of family members, spouses, and partners of patients admitted to surgical, medical, and trauma ICUs at a large academic medical center. Two validated instruments, the Learned Helplessness Scale and the Perceived Stress Scale, were used, and self-report of patient clinical characteristics and subject demographics were collected. RESULTS Four hundred ninety-nine family members were assessed. Of these, 238 of 460 (51.7%) had responses consistent with a significant degree of learned helplessness. Among surrogate decision-makers, this proportion was 50% (92 of 184). Characteristics associated with significant learned helplessness included grade or high school education (OR, 3.27; 95% CI, 1.29-8.27; P = .01) and Perceived Stress Scale score > 18 (OR, 4.15; 95% CI, 2.65-6.50; P < .001). The presence of a patient advance directive or do not resuscitate (DNR) order was associated with reduced odds of significant learned helplessness (OR, 0.56; 95% CI, 0.32-0.98; P = .05). CONCLUSIONS The majority of family members of patients in the ICU experience significant learned helplessness. Risk factors for learned helplessness include lower educational levels, absence of an advance directive or DNR order, and higher stress levels among family members. Significant learned helplessness in family members may have negative implications in the collaborative decision-making process.

Acute immunomodulatory effects of binge alcohol ingestion

BACKGROUND Blood alcohol is present in a third of trauma patients and has been associated with organ dysfunction. In both human studies and in animal models, it is clear that alcohol intoxication exerts immunomodulatory effects several hours to days after exposure, when blood alcohol is no longer detectable. The early immunomodulatory effects of alcohol while blood alcohol is still elevated are not well understood. METHODS Human volunteers achieved binge alcohol intoxication after high-dose alcohol consumption. Blood was collected for analysis prior to alcohol ingestion, and 20 min, 2 h, and 5 h after alcohol ingestion. Flow cytometry was performed on isolated peripheral blood mononuclear cells, and cytokine generation in whole blood was measured by enzyme-linked immunosorbent assay (ELISA) after 24-h stimulation with lipopolysaccharide (LPS) and phytohemagglutinin-M (PHA) stimulation. RESULTS An early pro-inflammatory state was evident at 20 min when blood alcohol levels were ∼130 mg/dL, which was characterized by an increase in total circulating leukocytes, monocytes, and natural killer cells. During this time, a transient increase in LPS-induced tumor necrosis factor (TNF)-α levels and enhanced LPS sensitivity occurred. At 2 and 5 h post-alcohol binge, an anti-inflammatory state was shown with reduced numbers of circulating monocytes and natural killer cells, attenuated LPS-induced interleukin (IL)-1β levels, and a trend toward increased interleukin (IL)-10 levels. CONCLUSIONS A single episode of binge alcohol intoxication exerted effects on the immune system that caused an early and transient pro-inflammatory state followed by an anti-inflammatory state.

A randomized, controlled trial of enhanced cleaning to reduce contamination of healthcare worker gowns and gloves with multidrug-resistant bacteria

OBJECTIVE. To determine whether enhanced daily cleaning would reduce contamination of healthcare worker (HCW) gowns and gloves with methicillin-resistant Staphylococcus aureus (MRSA) or multidrug-resistant Acinetobacter baumannii (MDRAB). DESIGN. A cluster-randomized controlled trial. SETTING. Four intensive care units (ICUs) in an urban tertiary care hospital. PARTICIPANTs. ICU rooms occupied by patients colonized with MRSA or MDRAB. INTERVENTION. Extra enhanced daily cleaning of ICU room surfaces frequently touched by HCWs. RESULTS. A total of 4,444 cultures were collected from 132 rooms over 10 months. Using fluorescent dot markers at 2,199 surfaces, we found that 26% of surfaces in control rooms were cleaned and that 100% of surfaces in experimental rooms were cleaned (P < .001). The mean proportion of contaminated HCW gowns and gloves following routine care provision and before leaving the rooms of patients with MDRAB was 16% among control rooms and 12% among experimental rooms (relative risk, 0.77 [95% confidence interval, 0.28-2.11]; P = .23). For MRSA, the mean proportions were 22% and 19%, respectively (relative risk, 0.89 [95% confidence interval, 0.50-1.53]; P = .16). DISCUSSION. Intense enhanced daily cleaning of ICU rooms occupied by patients colonized with MRSA or MDRAB was associated with a nonsignificant reduction in contamination of HCW gowns and gloves after routine patient care activities. Further research is needed to determine whether intense environmental cleaning will lead to significant reductions and fewer infections.

Decreased mortality resulting from a multicomponent intervention in a tertiary care medical intensive care unit.

Objective:To evaluate whether a multicomponent intervention, particularly increasing staff, can achieve reductions in patient mortality in an already high-intensity, Leapfrog-compliant medical intensive care unit. Design:Retrospective, observational study. Setting:Medical intensive care unit of a tertiary care, academic medical center. Patients:A total of 1,263 patients admitted between April 19, 2004 and April 18, 2006 (before the organizational change) were compared with 2,424 patients admitted between September 5, 2006 and September 4, 2008. Interventions:A multicomponent intervention including the physical move from a 10-bed to a 29-bed medical intensive care unit with larger patient rooms, the initiation of 24-hr critical care specialist coverage in the medical intensive care unit, an increase in the respiratory therapist:patient ratio, and the addition of a clinical pharmacist to the multidisciplinary team. Measurements and Main Results:Measurements were made based on mortality in the intensive care unit and in-hospital. Patient comorbidity as measured by the Charlson score did not change after the intervention (2.7 ± 2.7 vs. 2.8 ± 2.6, p = .62), nor did the acuity of illness as measured by the case mix index (3.0 ± 3.7 vs. 3.1 ± 3.8, p = .69). The unadjusted medical intensive care unit mortality decreased from 18.4% to 14.9% (p = .006), as did in-hospital mortality (from 25.8% to 21.7%, p = .005). The reduction in medical intensive care unit mortality was consistent in the multivariable regression with adjustment for multiple possible confounders (odds ratio = 0.74, 95% confidence interval: 0.61–0.91, p = .003), as was the reduction in hospital mortality (odds ratio = 0.74, 95% confidence interval: 0.62–0.88, p = .001). In mechanically ventilated patients, there was an increase in median 28-day ventilator-free days (21, interquartile range 0–25 vs. 22, interquartile range 0–26, p = .04). An increase in median medical intensive care unit (2.4, interquartile range 1.1–5.2 vs. 2.7, interquartile range 1.3–5.9), p = .009) but not hospital (8.3, interquartile range 4.1–17.0 vs. 8.2, interquartile range 4.0–16.8; p = .851) length of stay in days occurred with the intervention. The mean daily dosing of fentanyl and lorazepam decreased after the intervention. Conclusions:A multicomponent reorganization of medical intensive care unit services was associated with important reductions in mortality for medical intensive care unit patients, as well as an increased number of ventilator-free days. Substantial and sustained changes in clinically important outcomes may be obtained from organizational changes.

Transfusion practice in the intensive care unit: a 10-year analysis

BACKGROUND: Clinical guidelines recommend a restrictive transfusion strategy in nonhemorrhaging critically ill patients.

Peer Support as a Novel Strategy to Mitigate Post-Intensive Care Syndrome.

ABSTRACT Post‐intensive care syndrome, a condition defined by new or worsening impairment in cognition, mental health, and physical function after critical illness, has emerged in the past decade as a common and life‐altering consequence of critical illness. New strategies are urgently needed to mitigate the risk of neuropsychological and functional impairment common after critical illness and to prepare and support survivors on their road toward recovery. The present state of critical care survivorship is described, and postdischarge care delivery in the United States and the potential impact of the present‐day fragmented model of care delivery are detailed. A novel strategy that uses peer support groups could more effectively meet the needs of survivors of critical illness and mitigate post‐intensive care syndrome.
