Simulation-Based Education Enhances Patient Safety Behaviors During Central Venous Catheter Placement.

OBJECTIVE: We describe the effect of simulation-based education on residents' adherence to protocols for and performance of central venous access. METHODS: Internal medicine and emergency medicine residents underwent a central venous access course that included a lecture, video presentation, readings, and simulation demonstrations presented by faculty. Baseline data were collected before the course was initiated. After a skills session where they rehearsed their ultrasound-guided central venous access skills, residents were evaluated using a procedural checklist and written knowledge exam. Residents also completed questionnaires regarding confidence in performing ultrasound-guided central venous access and opinions about the training course. RESULTS: Residents demonstrated significant improvement on the written knowledge exam (P < 0.0001) and Standard Protocol Checklist (P < 0.0001) after the training course. Training improved a number of patient safety elements, including adherence to sterile technique, transparent dressing, discarding sharps, and ordering postprocedure x-rays. However, a number of residents failed to wash their hands, prepare with chlorhexidine, drape the patient using a sterile technique, anesthetize the site, and perform a preprocedure time-out. Significant improvement in procedural skills was also noted for reduction in skin-to-vein time (P < 0.003) as well as a reduction in number of residents who punctured the carotid artery (P < 0.02). CONCLUSIONS: Simulation-based education significantly improved residents' knowledge and procedural skills along with their confidence. Adherence to the protocol also improved. This study illustrates that simulation-based education can improve patient safety through training and protocols.

Diagnosis and Treatment of Adults with Community-acquired Pneumonia. An Official Clinical Practice Guideline of the American Thoracic Society and Infectious Diseases Society of America.

Background: This document provides evidence-based clinical practice guidelines on the management of adult patients with community-acquired pneumonia.Methods: A multidisciplinary panel conducted pragmatic systematic reviews of the relevant research and applied Grading of Recommendations, Assessment, Development, and Evaluation methodology for clinical recommendations.Results: The panel addressed 16 specific areas for recommendations spanning questions of diagnostic testing, determination of site of care, selection of initial empiric antibiotic therapy, and subsequent management decisions. Although some recommendations remain unchanged from the 2007 guideline, the availability of results from new therapeutic trials and epidemiological investigations led to revised recommendations for empiric treatment strategies and additional management decisions.Conclusions: The panel formulated and provided the rationale for recommendations on selected diagnostic and treatment strategies for adult patients with community-acquired pneumonia.

Agreement With Consensus Statements on End-of-Life Care: A Description of Variability at the Level of the Provider, Hospital, and Country.

OBJECTIVES: To develop an enhanced understanding of factors that influence providers' views about end-of-life care, we examined the contributions of provider, hospital, and country to variability in agreement with consensus statements about end-of-life care. DESIGN AND SETTING: Data were drawn from a survey of providers' views on principles of end-of-life care obtained during the consensus process for the Worldwide End-of-Life Practice for Patients in ICUs study. SUBJECTS: Participants in Worldwide End-of-Life Practice for Patients in ICUs included physicians, nurses, and other providers. Our sample included 1,068 providers from 178 hospitals and 31 countries. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We examined views on cardiopulmonary resuscitation and withholding/withdrawing life-sustaining treatments, using a three-level linear mixed model of responses from providers within hospitals within countries. Of 1,068 providers from 178 hospitals and 31 countries, 1% strongly disagreed, 7% disagreed, 11% were neutral, 44% agreed, and 36% strongly agreed with declining to offer cardiopulmonary resuscitation when not indicated. Of the total variability in those responses, 98%, 0%, and 2% were explained by differences among providers, hospitals, and countries, respectively. After accounting for provider characteristics and hospital size, the variance partition was similar. Results were similar for withholding/withdrawing life-sustaining treatments. CONCLUSIONS: Variability in agreement with consensus statements about end-of-life care is related primarily to differences among providers. Acknowledging the primary source of variability may facilitate efforts to achieve consensus and improve decision-making for critically ill patients and their family members at the end of life.

Interprofessional Shared Decision-Making in the ICU: A Systematic Review and Recommendations From an Expert Panel.

OBJECTIVES: There is growing recognition that high-quality care for patients and families in the ICU requires exemplary interprofessional collaboration and communication. One important aspect is how the ICU team makes complex decisions. However, no recommendations have been published on interprofessional shared decision-making. The aim of this project is to use systematic review and normative analysis by experts to examine existing evidence regarding interprofessional shared decision-making, describe its principles and provide ICU clinicians with recommendations regarding its implementation. DATA SOURCES: We conducted a systematic review using MEDLINE, Cumulative Index to Nursing and Allied Health Literature, and Cochrane databases and used normative analyses to formulate recommendations regarding interprofessional shared decision-making. STUDY SELECTION: Three authors screened titles and abstracts in duplicate. DATA SYNTHESIS: Four papers assessing the effect of interprofessional shared decision-making on quality of care were identified, suggesting that interprofessional shared decision-making is associated with improved processes and outcomes. Five recommendations, largely based on expert opinion, were developed: 1) interprofessional shared decision-making is a collaborative process among clinicians that allows for shared decisions regarding important treatment questions; 2) clinicians should consider engaging in interprofessional shared decision-making to promote the most appropriate and balanced decisions; 3) clinicians and hospitals should implement strategies to foster an ICU climate oriented toward interprofessional shared decision-making; 4) clinicians implementing interprofessional shared decision-making should consider incorporating a structured approach; and 5) further studies are needed to evaluate and improve the quality of interprofessional shared decision-making in ICUs. CONCLUSIONS: Clinicians should consider an interprofessional shared decision-making model that allows for the exchange of information, deliberation, and joint attainment of important treatment decisions.

Pragmatic methods to avoid intensive care unit admission when it does not align with patient and family goals.

For patients with chronic, life-limiting illnesses, admission to the intensive care unit (ICU) near the end of life might not improve patient outcomes or be consistent with patient and family values, goals, and preferences. In this context, advance care planning and palliative care interventions designed to clarify patients' values, goals, and preferences have the potential to reduce provision of high-intensity interventions that are unwanted or non-beneficial. In this Series paper, we have assessed interventions that are effective at helping patients with chronic, life-limiting illnesses to avoid an unwanted ICU admission. The evidence found was largely from observational studies, with considerable heterogeneity in populations, methods, and types of interventions. Results from randomised trials of interventions to improve communication about goals of care are scarce, of variable quality, and mixed. Although observational studies show that advance care planning and palliative care interventions are associated with a reduced number of ICU admissions at the end of life, causality has not been well established. Using the available evidence we suggest recommendations to help to avoid ICU admission when it does not align with patient and family values, goals, and preferences and conclude with future directions for research.

Residents' Preferences and Performance of Three Techniques for Ultrasound-Guided Central Venous Cannulation After Simulation Training.

BACKGROUND: Obtaining central venous cannulation of the internal jugular vein is an important skill for physicians to master. To our knowledge, no studies to date have examined residents' preferences or the safety of the oblique approach compared to other approaches. This study compared medical residents' preferences for and performance of ultrasound-guided central venous access using the transverse, longitudinal, and oblique approaches. METHODS: Emergency medicine and internal medicine residents (n = 72) at an urban community hospital participated in a central venous access course. To assess the residents' preferences, residents were asked to rank the transverse, longitudinal, and oblique approaches as first, second, or third. In addition to preference, skin-to-vein time, carotid artery puncture, and successful completion on the first attempt during a final skills analysis were measured. RESULTS: During the final skills analysis, the majority (87.5%) of residents preferred the transverse approach. The oblique approach had a significantly larger proportion of failures of technique than the transverse approach (P = 0.02). No significant differences in successful cannulation on the first attempt, skin-to-vein time, or carotid artery puncture among the 3 approaches were found during the final skills assessment. CONCLUSION: The majority of residents preferred the transverse approach to the longitudinal and oblique approaches. Although no significant differences among the 3 approaches were found in performance measures, more failures of technique occurred with the oblique approach. This study suggests that novices may require in-depth training and supervision to become proficient with the oblique approach.

Understanding Response Rates to Surveys About Family Members' Psychological Symptoms After Patients' Critical Illness.

CONTEXT: Achieving adequate response rates from family members of critically ill patients can be challenging, especially when assessing psychological symptoms. OBJECTIVES: To identify factors associated with completion of surveys about psychological symptoms among family members of critically ill patients. METHODS: Using data from a randomized trial of an intervention to improve communication between clinicians and families of critically ill patients, we examined patient-level and family-level predictors of the return of usable surveys at baseline, three months, and six months (n = 181, 171, and 155, respectively). Family-level predictors included baseline symptoms of psychological distress, decisional independence preference, and attachment style. We hypothesized that family with fewer symptoms of psychological distress, a preference for less decisional independence, and secure attachment style would be more likely to return questionnaires. RESULTS: We identified several predictors of the return of usable questionnaires. Better self-assessed family member health status was associated with a higher likelihood and stronger agreement with a support-seeking attachment style with a lower likelihood, of obtaining usable baseline surveys. At three months, family-level predictors of return of usable surveys included having usable baseline surveys, status as the patient's legal next of kin, and stronger agreement with a secure attachment style. The only predictor of receipt of surveys at six months was the presence of usable surveys at three months. CONCLUSION: We identified several predictors of the receipt of surveys assessing psychological symptoms in family of critically ill patients, including family member health status and attachment style. Using these characteristics to inform follow-up mailings and reminders may enhance response rates.

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.

Family-centered outcomes during and after critical illness: current outcomes and opportunities for future investigation.

PURPOSE OF REVIEW: Family-centered outcomes during and after critical illness assess issues that are most important to family members. An understanding of family-centered outcomes is necessary to support the provision of family-centered care and to foster development of interventions to improve care and communication in the ICU. RECENT FINDINGS: Current family-centered outcomes in critical care include satisfaction with care, including end-of-life care, symptoms of psychological distress, and health-related quality of life. Novel measures include assessments of decisional conflict, decision regret, therapeutic alliance, and caregiver burden, as well as positive adaptations and resilience. SUMMARY: Critical illness places a significant burden on family members. A wide variety of family-centered outcomes are available to guide improvements in care and communication. Future research should focus on developing sensitive and responsive measures that capture key elements of the family member experience during and after critical illness.

Physicians' and Nurse Practitioners' Level of Pessimism About End-of-Life Care During Training: Does It Change Over Time?

CONTEXT: An enhanced understanding of trainee attitudes about end-of-life care is needed to inform interventions to improve clinician communication about dying and death. OBJECTIVES: To examine changes in trainee pessimism about end-of-life care over the course of one academic year and to explore predictors of pessimism among residents, fellows, and nurse practitioners. METHODS: We used baseline and follow-up surveys completed by trainees during a randomized controlled trial of an intervention to improve clinician communication skills. Surveys addressed trainee feelings about end-of-life care. Latent variable modeling was used to identify indicators of trainee pessimism, and this pessimism construct was used to assess temporal changes in trainee attitudes about end-of-life care. We also examined predictors of trainee pessimism at baseline and follow-up. Data were available for 383 trainees from two training programs. RESULTS: There was a significant decrease in pessimism between baseline and follow-up assessments. Age had a significant inverse effect on baseline pessimism, with older trainees being less pessimistic. There was a direct association of race/ethnicity on pessimism at follow-up, with greater pessimism among minority trainees (P = 0.028). The model suggests that between baseline and follow-up, pessimism among younger white non-Hispanic trainees decreased, whereas pessimism among younger trainees in racial/ethnic minorities increased over the same period. CONCLUSION: Overall, trainee pessimism about end-of-life care decreases over time. Pessimism about end-of-life care among minority trainees may reflect the influence of culture on clinician attitudes about communication with seriously ill patients. Further research is needed to understand the evolution of trainee attitudes about end-of-life care during clinical training.

The Influence of Race/Ethnicity and Education on Family Ratings of the Quality of Dying in the ICU.

CONTEXT: Racial and ethnic differences in end-of-life care may be attributable to both patient preferences and health-care disparities. Identifying factors that differentiate preferences from disparities may enhance end-of-life care for critically ill patients and their families. OBJECTIVES: To understand the association of minority race/ethnicity and education with family ratings of the quality of dying and death, taking into consideration possible markers of patient and family preferences for end-of-life care as mediators of this association. METHODS: Data were obtained from 15 intensive care units participating in a cluster-randomized trial of a palliative care intervention. Family members of decedents completed self-report surveys evaluating quality of dying. We used regression analyses to identify associations between race/ethnicity, education, and quality of dying ratings. We then used path analyses to investigate whether advance directives and life-sustaining treatment acted as mediators between patient characteristics and ratings of quality of dying. RESULTS: Family members returned 1290 surveys for 2850 decedents. Patient and family minority race/ethnicity were both associated with lower ratings of quality of dying. Presence of a living will and dying in the setting of full support mediated the relationship between patient race and family ratings; patient race exerted an indirect, rather than direct, effect on quality of dying. Family minority race had a direct effect on lower ratings of quality of dying. Neither patient nor family education was associated with quality of dying. CONCLUSION: Minority race/ethnicity was associated with lower family ratings of quality of dying. This association was mediated by factors that may be markers of patient and family preferences (living will, death in the setting of full support); family member minority race/ethnicity was directly associated with lower ratings of quality of dying. Our findings generate hypothesized pathways that require future evaluation.

Time to Death after Terminal Withdrawal of Mechanical Ventilation: Specific Respiratory and Physiologic Parameters May Inform Physician Predictions.

BACKGROUND: Discussions about withdrawal of life-sustaining therapies often include family members of critically ill patients. These conversations should address essential components of the dying process, including expected time to death after withdrawal. OBJECTIVES: The study objective was to aid physician communication about the dying process by identifying predictors of time to death after terminal withdrawal of mechanical ventilation. METHODS: We conducted an observational analysis from a single-center, before-after evaluation of an intervention to improve palliative care. We studied 330 patients who died after terminal withdrawal of mechanical ventilation. Predictors included patient demographics, laboratory, respiratory, and physiologic variables, and medication use. RESULTS: The median time to death for the entire cohort was 0.58 hours (interquartile range (IQR) 0.22-2.25 hours) after withdrawal of mechanical ventilation. Using Cox regression, independent predictors of shorter time to death included higher positive end-expiratory pressure (per 1 cm H2O hazard ratio [HR], 1.07; 95% CI 1.04-1.11); higher static pressure (per 1 cm H2O HR, 1.03; 95% CI 1.01-1.04); extubation prior to death (HR, 1.41; 95% CI 1.06-1.86); and presence of diabetes (HR, 1.75; 95% CI 1.25-2.44). Higher noninvasive mean arterial pressure predicted longer time to death (per 1 mmHg HR, 0.98; 95% CI 0.97-0.99). CONCLUSIONS: Comorbid illness and key respiratory and physiologic parameters may inform physician predictions of time to death after withdrawal of mechanical ventilation. An understanding of the predictors of time to death may facilitate discussions with family members of dying patients and improve communication about end-of-life care.

Estimating the effect of palliative care interventions and advance care planning on ICU utilization: a systematic review.

OBJECTIVE: We conducted a systematic review to answer three questions: 1) Do advance care planning and palliative care interventions lead to a reduction in ICU admissions for adult patients with life-limiting illnesses? 2) Do these interventions reduce ICU length of stay? and 3) Is it possible to provide estimates of the magnitude of these effects? DATA SOURCES: We searched MEDLINE, EMBASE, Cochrane Controlled Clinical Trials, and Cumulative Index to Nursing and Allied Health Literature databases from 1995 through March 2014. STUDY SELECTION: We included studies that reported controlled trials (randomized and nonrandomized) assessing the impact of advance care planning and both primary and specialty palliative care interventions on ICU admissions and ICU length of stay for critically ill adult patients. DATA EXTRACTION: Nine randomized controlled trials and 13 nonrandomized controlled trials were selected from 216 references. DATA SYNTHESIS: Nineteen of these studies were used to provide estimates of the magnitude of effect of palliative care interventions and advance care planning on ICU admission and length of stay. Three studies reporting on ICU admissions suggest that advance care planning interventions reduce the relative risk of ICU admission for patients at high risk of death by 37% (SD, 23%). For trials evaluating palliative care interventions in the ICU setting, we found a 26% (SD, 23%) relative risk reduction in length of stay with these interventions. CONCLUSIONS: Despite wide variation in study type and quality, patients who received advance care planning or palliative care interventions consistently showed a pattern toward decreased ICU admissions and reduced ICU length of stay. Although SDs are wide and study quality varied, the magnitude of the effect is possible to estimate and provides a basis for modeling impact on healthcare costs.

Quality of dying in the ICU: is it worse for patients admitted from the hospital ward compared to those admitted from the emergency department?

OBJECTIVE: Although most intensive care unit (ICU) admissions originate in the emergency department (ED), a substantial number of admissions arrive from hospital wards. Patients transferred from the hospital ward often share clinical characteristics with those admitted from the ED, but family expectations may differ. An understanding of the impact of ICU admission source on family perceptions of end-of-life care may help improve patient and family outcomes by identifying those at risk for poor outcomes. DESIGN AND SETTING: This was a cohort study of patients with chronic illness and acute respiratory failure requiring mechanical ventilation who died after admission to an ICU in any of the 14 participating hospitals in the Seattle-Tacoma area between 2003 and 2008 (n = 1,500). MEASUREMENTS: Using regression models adjusted for hospital site and patient-, nurse- and family-level characteristics, we examined associations between ICU admission source (hospital ward vs. ED) and (1) family ratings of satisfaction with ICU care; (2) family and nurse ratings of quality of dying; (3) chart-based indicators of palliative care. MAIN RESULTS: Admission from the hospital ward was associated with lower family ratings of quality of dying [ß -0.90, 95% confidence interval (CI) -1.54, -0.26, p = 0.006] and satisfaction (total score ß -3.97, 95% CI -7.89, -0.05, p = 0.047; satisfaction with care domain score ß -5.40, 95% CI -9.44, -1.36, p = 0.009). Nurses did not report differences in quality of dying. Patients from hospital wards were less likely to have family conferences [odds ratio (OR) 0.68, 95% CI 0.52, 0.88, p = 0.004] or discussion of prognosis in the first 72 h after ICU admission (OR 0.72, 95% CI 0.56, 0.91, p = 0.007) but were more likely to receive spiritual care (OR 1.48, 95% CI 1.14, 1.93, p = 0.003) or have life support withdrawn (OR 1.38, 95% CI 1.04, 1.82, p = 0.025). CONCLUSION: Admission from the hospital ward is associated with family perceptions of a lower quality of dying and less satisfaction with ICU care. Differences in receipt of palliative care suggest that family of patients from the hospital ward receive less communication. Nurse ratings of quality of dying did not significantly differ by ICU admission source, suggesting dissimilarities between family and nurse perspectives. This study identifies a patient population at risk for poor quality palliative and end-of-life care. Future studies are needed to identify interventions to improve care for patients who deteriorate on the wards following hospital admission.

Posttraumatic stress disorder among survivors of critical illness: creation of a conceptual model addressing identification, prevention, and management.

Quality of life is frequently impaired among survivors of critical illness, and psychiatric morbidity is an important element contributing to poor quality of life in these patients. Among potential manifestations of psychiatric morbidity following critical illness, symptoms of posttraumatic stress are prevalent and intricately linked to the significant stressors present in the intensive care unit (ICU). As our understanding of the epidemiology of post-ICU posttraumatic stress disorder improves, so must our ability to identify those at highest risk for symptoms in the period of time following critical illness and our ability to implement strategies to prevent symptom development. In addition, a focus on strategies to address clinically apparent psychiatric morbidity will be essential. Much remains to be understood about the identification, prevention, and management of this significant public health problem. This article addresses the importance of uniformity in future epidemiologic studies, proposes framing of risk factors into those likely to be modifiable versus non-modifiable, and provides an assessment of modifiable risk factors in the context of a novel conceptual model that offers insight into potential strategies to attenuate symptoms of posttraumatic stress among survivors of critical illness.
