Outcomes of prolonged mechanical ventilation and tracheostomy in critically ill elderly patients: a historical cohort study.

PURPOSE: With an aging global population, the increased proportion of elderly patients in the intensive care unit (ICU) raises important questions regarding optimal management. Currently, data on tracheostomy and its outcomes in the elderly are limited. We aimed to determine the in-hospital survival of elderly ICU patients following tracheostomy, and describe impacts on discharge disposition and functional outcomes. METHODS: We conducted a historical cohort study at two academic hospitals in Toronto. All patients aged ≥ 70 yr who received a tracheostomy during their ICU stay between January 2010 and June 2016 were included in a retrospective chart review. Data on patient demographics, frailty, tracheostomy indication, and outcomes were collected. RESULTS: The study included 270 patients with a mean (standard deviation) age of 81 (6) yr. The majority were admitted to ICU for respiratory failure (147/270, 54%) and received a tracheostomy for prolonged mechanical ventilation (202/270, 75%). Intensive care unit and hospital mortality were 26% (68/270) and 46% (125/270), respectively. Twenty-five percent (67/270) of patients were decannulated during hospital admission, a median [interquartile range (IQR)] of 41 [25-68] days after tracheostomy. Intensive care unit and hospital length of stay were 31 [17-53] and 81 [46-121] days, respectively. At hospital discharge, 6% (17/270) of patients were discharged home, all were frail (median Clinical Frailty Score of 7) and most were tube-fed (101/270, 70%), unable to speak (81/270, 56%), and nonambulatory (98/270, 68%). CONCLUSIONS: In patients aged ≥ 70 yr, tracheostomy during ICU stay marked a transition toward prolonged chronic critical illness. Nearly half of the patients died during the admission, and although a quarter were successfully decannulated, the majority of survivors were left with severe frailty and functional impairment.

RéSUMé: OBJECTIF: Avec le vieillissement de la population mondiale, la proportion accrue de patients âgés aux soins intensifs (USI) soulève d'importantes questions concernant leur prise en charge optimale. À l'heure actuelle, les données sur la trachéotomie et ses issues chez les personnes âgées sont limitées. Nous avions pour objectif de déterminer la survie hospitalière des patients âgés en soins intensifs après une trachéotomie et d'examiner les impacts sur la disposition au congé et les devenirs fonctionnels. MéTHODE: Nous avons mené une étude de cohorte historique dans deux hôpitaux universitaires de Toronto. Tous les patients âgés de ≥ 70 ans ayant reçu une trachéotomie pendant leur séjour à l'USI entre janvier 2010 et juin 2016 ont été inclus dans un examen rétrospectif des dossiers. Les données sur la démographie des patients, leur fragilité, l'indication pour la trachéotomie et les devenirs ont été recueillies. RéSULTATS: L'étude a inclus 270 patients avec un âge moyen (écart type) de 81 (6) ans. La majorité d'entre eux ont été admis à l'USI pour insuffisance respiratoire (147/270, 54 %) et ont subi une trachéotomie pour une ventilation mécanique prolongée (202/270, 75 %). La mortalité à l'USI et à l'hôpital était de 26 % (68/270) et 46 % (125/270), respectivement. Vingt-cinq pour cent (67/270) des patients ont été décanulés pendant leur admission à l'hôpital, [écart interquartile (ÉIQ)] 41 [25-68] jours après la trachéotomie en moyenne. La durée du séjour à l'USI et à l'hôpital était de 31 [17-53] et 81 [46-121] jours, respectivement. Lors du congé de l'hôpital, 6 % (17/270) des patients sont rentrés chez eux, tous étaient fragiles (score médian de fragilité clinique de 7) et la plupart étaient nourris par sonde (101/270, 70 %), incapables de parler (81/270, 56 %) et non ambulatoires (98/270, 68 %). CONCLUSIONS: Chez les patients âgés de ≥ 70 ans, la trachéotomie pendant le séjour aux soins intensifs a marqué une transition vers une maladie chronique grave prolongée. Près de la moitié des patients sont décédés pendant leur séjour, et bien qu'un quart aient été décanulés avec succès, la majorité des survivants se sont retrouvés avec une fragilité sévère et une déficience fonctionnelle.

Exploring spiritual health practitioners' roles and activities in critical care contexts.

Family members of patients admitted to the intensive care unit (ICU) experience multidimensional distress. Many clinicians lack an understanding of spiritual health practitioners' role and approaches to providing spiritual support. Through semi-structured interviews and focus groups with 10 spiritual health practitioners, we explored how spiritual health practitioners support families of patients in the ICU to better understand their scope of practice and role within an interdisciplinary critical care team. Spiritual health practitioners' work was described through clinical roles (family support, clinician support, bridging family members and clinicians), activities (companioning, counseling, facilitating difficult conversations, addressing individual needs), tensions (within and between roles and activities, navigating between hope and anticipated clinical trajectory, balancing supportive care and workload) and foundational principles (holistic perspective, resilience). A more comprehensive understanding of these roles and skills may enable clinicians to better integrate spiritual health practitioners into the fabric of care for patients, families, and clinicians themselves.

Vicarious spiritual distress in intensive care unit healthcare providers: A qualitative study.

OBJECTIVES: To explore the impact of caring for family members experiencing spiritual distress on Intensive Care Unit healthcare providers. DESIGN: A qualitative study involving interviews and focus groups between May 2016 and April 2017. PARTICIPANTS: Intensive care healthcare providers from nine teaching and three non-teaching units across Alberta, Canada. MEASUREMENTS: Transcribed data were analysed using interpretive description. FINDINGS: Forty-two participants variably described experiences of vicarious spiritual distress, along with coping strategies and outcomes related to these experiences. Vicarious spiritual distress was experienced as sorrow/distress, helplessness and preoccupation/rumination. Coping strategies were both adaptive (self-awareness/reflection, reframing/resiliency, team support/debriefing, self-care, accepting limitations) and maladaptive (compartmentalising/distancing, substance use). Lastly, the emotional burden of these experiences resulted in both favourable (satisfaction, appreciation) and unfavourable (moral distress, burnout, hopelessness) outcomes. CONCLUSION: Our findings describe the novel concept of vicarious spiritual distress as experienced by intensive care healthcare providers and highlight the importance of identifying effective ways to support these professionals throughout their careers to prevent unfavorable outcomes and the perpetuation of maladaptive coping strategies. The adaptive coping strategies described in this study may help inform wellness initiatives and resiliency training tailored to intensive care healthcare providers.

Critical care providers' support of families in bereavement: a mixed-methods study.

PURPOSE: When people die in intensive care units (ICUs), as many as half of their family members may experience a severe grief reaction. While families report a need for bereavement support, most ICUs do not routinely follow-up with family members. Clinicians are typically involved in supporting families during death and dying, yet little is known about how they work with families in bereavement. Our goal was to explore how clinicians support bereaved families, identify factors that facilitate and hinder support, and understand their interest and needs for follow-up. METHODS: Mixed-methods study of nurses and physicians working in one of nine adult medical-surgical ICUs in academic hospitals across Canada. Qualitative interviews followed quantitative surveys to reflect, expand, and explain the quantitative results. RESULTS: Both physicians and nurses perceived that they provided empathetic support to bereaved families. Emotional engagement was a crucial element of support, but clinicians were not always able to engage with families because of their roles, responsibilities, experiences, or unit resources. Another important factor that could facilitate or challenge engagement was the degree to which families accepted death. Clinicians were interested in participating in a follow-up bereavement program, but their participation was contingent on time, training, and the ability to manage their own emotions related to death and bereavement in the ICU. CONCLUSIONS: Multiple opportunities were identified to enhance current bereavement support for families, including the desire of ICU clinicians for formal follow-up programs. Many psychological, sociocultural, and structural factors would need to be considered in program design.

RéSUMé: OBJECTIF: Lorsque des personnes décèdent dans une unité de soins intensifs (USI), jusqu'à la moitié des membres de leur famille pourraient souffrir d'une réaction émotionnelle grave. Bien que les familles rapportent le besoin d'un soutien en cas de deuil, la plupart des USI ne font pas un suivi de routine avec les membres de la famille. Les cliniciens sont traditionnellement impliqués dans le soutien aux familles pendant la mort et le décès, mais nous ne connaissons que peu de choses concernant leur travail avec les familles en deuil. Notre objectif était d'explorer la façon dont les cliniciens viennent en soutien aux familles en deuil, d'identifier les facteurs qui facilitent ou entravent le soutien, et de comprendre leur intérêt et leurs besoins en matière de suivi. MéTHODE: Nous avons réalisé une étude par méthodes mixtes auprès du personnel infirmier et des médecins travaillant dans l'une de neuf USI médico-chirurgicales pour adultes dans des hôpitaux universitaires du Canada. Des entretiens qualitatifs suivaient des sondages quantitatifs afin de refléter, approfondir et expliquer les résultats quantitatifs. RéSULTATS: Selon leur perception, les médecins et le personnel infirmier fournissent un soutien empathique aux familles en deuil. L'implication émotionnelle a été identifiée comme étant un élément crucial du soutien, mais les cliniciens ne sont pas toujours capables de s'impliquer auprès des familles en raison de leurs rôles, de leurs responsabilités, de leurs expériences ou des ressources de l'unité. Un autre facteur important qui pourrait faciliter ou au contraire entraver leur implication est la mesure dans laquelle les familles acceptent la mort. Les cliniciens seraient intéressés à participer à un programme de suivi de deuil, mais leur participation dépend de leur temps, de leur formation et de leur capacité à gérer leurs propres émotions liées à la mort et au deuil à l'USI. CONCLUSION: De nombreuses cibles ont été identifiées pour améliorer le soutien actuel aux familles en deuil, y compris le désir des cliniciens de l'USI de disposer de programmes formels de suivi. Il faudra toutefois tenir compte de nombreux facteurs psychologiques, socioculturels et structurels dans la conception de tels programmes.

Challenges and Enablers of Spiritual Care for Family Members of Patients in the Intensive Care Unit.

Spiritual care has been recognized as important to family members of critically ill patients, although it is often not integrated within clinical practice. We conducted focus groups and interviews with family members, spiritual health practitioners, and clinicians who work in the intensive care unit (ICU) to explore their experiences of working with family members experiencing spiritual distress in this setting. Challenges and factors that enable identification and support for spiritual distress were identified, as well as suggestions for improvement.

A qualitative study of bereaved family members with complicated grief following a death in the intensive care unit.

PURPOSE: Grief is a normal reaction, and most family members (FMs) experience grief following a death. Typically, grief subsides without any major psychological or medical impairment. Nevertheless, some FMs may experience complicated grief (CG) reactions, with symptoms lasting months or years, and CG is particularly prominent among FMs of those who die in the intensive care unit (ICU). The purpose of this study was to examine how FMs experience grief, particularly CG, to inform future early screening and support programs in the ICU. METHODS: This was a multicentre qualitative study focusing on semi-structured interviews with FMs who displayed symptoms of CG. Family members of patients who died in the ICU and who had a six-month inventory of CG score > 25 were included. Semi-structured interviews were conducted with FMs post-loss, with follow-up interviews three months after the initial interviews. RESULTS: Major themes identified following thematic analysis from eight participants with CG included 1) ante-mortem experience: the impact of the ICU experience prior to death of a loved on subsequent grief; 2) post-mortem experience: unpredictable post death reactions; 3) coping strategies: techniques used to reduce the severity of grief reactions; 4) sources of support: focusing on resources that the FM draws from for emotional support; and 5) perspectives on future ICU bereavement screening and support programs: advice that FM participants provided for future bereavement support. CONCLUSION: Bereaved FMs with CG described their experiences with grief, how ICU events influenced their bereavement, their coping strategies and sources of support, and their advice for future bereavement support programs for FMs of deceased ICU patients.

RéSUMé: OBJECTIF: Le deuil est une réaction normale et la plupart des membres d'une famille l'éprouvent après un décès. Habituellement, le deuil décroit sans laisser de troubles psychologiques ou médicaux majeurs. Néanmoins, certains membres d'une famille peuvent présenter des réactions de deuil compliquées, avec des symptômes durant des mois ou des années et ce deuil compliqué est particulièrement visible lorsqu'un membre de la famille est décédé dans une unité de soins intensifs (USI). Cette étude avait pour objectif d'examiner comment les membres d'une famille vivent un deuil, en particulier un deuil compliqué, pour renseigner de futurs programmes de dépistage précoce et de soutien en USI. MéTHODES: Il s'est agi d'une étude qualitative multicentrique utilisant principalement des entretiens semi-structurés avec des membres de familles qui présentaient des symptômes de deuil compliqué. Des membres de la famille de patients décédés en USI qui dans les derniers 6 mois avaient un score > 25 au questionnaire de deuil compliqué ont été inclus. Les entretiens semi-structurés ont été menés après le décès avec des membres de la famille et des entretiens de suivi ont eu lieu trois mois après l'entretien initial. RéSULTATS: Les principaux thèmes identifiés après une analyse thématique de huit participants ayant un deuil compliqué ont inclus : 1) le vécu avant le décès : l'impact de l'expérience de l'USI avant le décès d'un être cher sur le deuil qui a suivi; 2) le vécu après le décès : les réactions imprévisibles après le décès; 3) les stratégies de réponse face au stress : Les techniques utilisées pour réduire les réactions de deuil; 4) les sources de soutien : en se concentrant sur les ressources que le membre de la famille utilise pour un soutien émotionnel; et 5) le point de vue sur de futurs programmes de dépistage et de soutien en USI : les conseils que les membres participants des familles ont donnés pour un futur soutien du deuil. CONCLUSION: Les membres de familles endeuillées présentant un deuil compliqué ont décrit leur vécu du deuil, comment les événements vécus en USI l'ont influencé, leurs stratégies de réponse et la source des soutiens utilisés, ainsi que leurs conseils pour de futurs programmes de soutien du deuil destinés aux familles de patients décédés en USI.

Development of a Clinical Guide for Identifying Spiritual Distress in Family Members of Patients in the Intensive Care Unit.

Background: Spirituality is important for many family members of patients in the intensive care unit (ICU). Clinicians without training in spiritual care experience difficulty identifying when family members are experiencing distress of a spiritual nature. Objective: The purpose of this study was to develop a guide to help clinicians working in the ICU identify family members who may benefit from specialized spiritual support. Design: Cross-sectional study. Setting/Subjects: A national sample of spiritual health practitioners, family members, and ICU clinicians. Subjects: A panel of 21 spiritual health practitioners participated in a modified Delphi process to achieve consensus on items that suggest spiritual distress among family members of patients in the ICU through three rounds of remote review followed by an in-person conference and a final round of panelist feedback. Feedback on the final set of items was obtained from an end-user group of four family members and six ICU clinicians. Measurements: Quantitative data were summarized with descriptive statistics. Content analysis was used to analyze written comments. Results: A total of 220 items were iteratively reviewed and rated by panelists. Forty-six items were identified as essential for inclusion and developed into a clinical guide, including an introduction (n = 1), definitions (n = 2), risk factors (n = 10), expressed concerns (n = 12), emotions (n = 7) and behaviors (n = 7) that may suggest spiritual distress, questions to identify spiritual needs (n = 6), and introducing spiritual support (n = 1). Conclusions: We have developed an evidence-informed clinical guide that may help clinicians in the ICU identify family members experiencing spiritual distress.

Spiritual Distress in Family Members of Critically Ill Patients: Perceptions and Experiences.

Background: Spiritual distress among family members of patients in the intensive care unit (ICU) has not been well characterized. This limits clinicians' understanding of how to best offer support. Objective: To explore how family members experience spiritual distress, and how it is recognized and support offered within the ICU context. Design: A qualitative study involving interviews and focus groups between May 2016 and April 2017. Setting/Subjects: Family members of ICU patients (n = 18), spiritual health practitioners (n = 10), and an interprofessional group of clinicians who work in the ICU (n = 32). Measurements: Transcribed data were analyzed using interpretive description. Results: The experience of spiritual distress was variably described by all three groups through concepts, modulators, expressions and manifestations, and ways in which spiritual distress was addressed. Concepts included loss of meaning, purpose and connection, tension in beliefs, and interconnected distress. Modulators were related to the patient and family context, the ICU context, and the relational context. Expressions and manifestations were unique and individual, involving verbal expressions of thoughts and emotions, as well as behavioral manifestations of coping. Clinical strategies for addressing spiritual distress were described through general principles, specific strategies for discussing spiritual distress, and ways in which spiritual support can be offered. Conclusions: Our study provides a rich description of how spiritual distress is experienced by family members of ICU patients, and how spiritual health practitioners and clinicians recognize spiritual distress and offer support. These findings will help inform clinician education and initiatives to better support families of critically ill patients.

Spiritual Distress Within Inpatient Settings-A Scoping Review of Patients' and Families' Experiences.

CONTEXT: Spiritual distress contributes to patients' and families' experiences of care. OBJECTIVES: To map the literature on how seriously ill patients and their family members experience spiritual distress within inpatient settings. METHODS: Our scoping review included four databases using search terms "existential" or "spiritual" combined with "angst," "anxiety," "distress," "stress," or "anguish." We included original research describing experiences of spiritual distress among adult patients or family members within inpatient settings and instrument validation studies. Each study was screened in duplicate for inclusion, and the data from included articles were extracted. Themes were identified, and data were synthesized. RESULTS: Within the 37 articles meeting inclusion criteria, we identified six themes: conceptualizing spiritual distress (n = 2), diagnosis and prevalence (n = 7), assessment instrument development (n = 5), experiences (n = 12), associated variables (n = 12), and barriers and facilitators to clinical support (n = 5). The majority of studies focused on patients; two studies focused on family caregivers. The most common clinical settings were oncology (n = 19) and advanced disease (n = 19). Terminology to describe spiritual distress varied among studies. The prevalence of at least moderate spiritual distress in patients was 10%-63%. Spiritual distress was experienced in relation to self and others. Associated variables included demographic, physical, cognitive, and psychological factors. Barriers and facilitators were described. CONCLUSION: Patients' and families' experiences of spiritual distress in the inpatient setting are multifaceted. Important gaps in the literature include a narrow spectrum of populations, limited consideration of family caregivers, and inconsistent terminology. Research addressing these gaps may improve conceptual clarity and help clinicians better identify spiritual distress.

Validation of quality indicators for end-of-life communication: results of a multicentre survey.

BACKGROUND: The lack of validated quality indicators is a major barrier to improving end-of-life communication and decision-making. We sought to show the feasibility of and provide initial validation for a set of quality indicators related to end-of-life communication and decision-making. METHODS: We administered a questionnaire to patients and their family members in 12 hospitals and asked them about advance care planning and goals-of-care discussions. Responses were used to calculate a quality indicator score. To validate this score, we determined its correlation with the concordance between the patients' expressed wishes and the medical order for life-sustaining treatments recorded in the hospital chart. We compared the correlation with concordance for the advance care planning component score with that for the goal-of-care discussion scores. RESULTS: We enrolled 297 patients and 209 family members. At all sites, both overall quality indicators and individual domain scores were low and there was wide variability around the point estimates. The highest-ranking institution had an overall quality indicator score (95% confidence interval) of 40% (36%-44%) and the lowest had a score of 18% (11%-25%). There was a strong correlation between the overall quality indicator score and the concordance measure (r = 0.72, p = 0.008); the estimated correlation between the advance care planning score and the concordance measure (r = 0.35) was weaker than that between the goal-of-care discussion scores and the concordance measure (r = 0.53). INTERPRETATION: Quality of end-of-life communication and decision-making appears low overall, with considerable variability across hospitals. The proposed quality indicator measure shows feasibility and partial validity. Study registration: ClinicalTrials.gov, no. NCT01362855.

A modified Delphi process to identify clinical and research priorities in patient and family centred critical care.

PURPOSE: To identify elements which enable patient and family centred care (PFCC) in the intensive care unit (ICU) and priorities for PFCC research. MATERIALS AND METHODS: We engaged a panel of multidisciplinary stakeholders in a modified Delphi process. Items generated from a literature review and panelist suggestions were rated in 3 successive rounds on a scale from 1 to 7. Median score was used to rate each item's priority, with 5 or more indicating "essential priority," 4 or 5 "moderate priority" and 3 or less "low priority." Interquartile range (IQR) was used to measure consensus, with IQR of 1 indicating "high" consensus, 2 "moderate" consensus, and 3 or greater "low" consensus. RESULTS: Six items were rated essential elements for facilitating PFCC with high consensus (flexible visiting hours, family participation in bedside care, trained family support person, interventions to facilitate continuity of care, staff education to support families, continuity of staff assignments). Three items were rated essential research topics: interventions to facilitate continuity of care following ICU discharge (moderate consensus), family participation in bedside care (low consensus), and decision aids for end of life decision-making (low consensus). CONCLUSIONS: Stakeholders identified clear and distinct priorities for PFCC in clinical care and research, though there was greater consensus for clinical care.

Discordance between patients' stated values and treatment preferences for end-of-life care: results of a multicentre survey.

BACKGROUND: Medical orders for the use of life-supports should be informed by patients' values and treatment preferences. The purpose of this study was to explore the internal consistency of patients' (or their family members') stated values, and the relationship between these values and expressed preferences. METHODS: We conducted a prospective study in 12 acute care hospitals in Canada. We administered a questionnaire to elderly patients and their family members about their values related to end-of-life (EOL) care, treatment preferences and decisional conflict. RESULTS: Of 513 patients and 366 family members approached, 278 patients (54%) and 225 family members (61%) consented to participate. Participants' most important stated values were to be comfortable and suffer as little as possible, to have more time with family, to avoid being attached to machines and tubes and that death not be prolonged. The least important stated value was that life be preserved. Based on prespecified expected associations between the various values measured, there were inconsistencies in participants' expressed value statements. With few exceptions, participants' expressed values were not associated with expected corresponding treatment preferences. Of the 109 (40%) patients and 95 (42%) family members who had made decisions about use of life-supports, 68 (56%) patients and 60 (59%) family members had decisional conflict. CONCLUSIONS: Decision-making regarding medical treatments at the EOL is inadequate. To reduce decisional conflict, patients and their families need more support to clarify their values and ensure that their preferences are grounded in adequate understanding of their illness and treatment options. TRIAL REGISTRATION NUMBER: NCT01362855.

Transitions to End-of-Life Care for Patients With Chronic Critical Illness: A Meta-Synthesis.

BACKGROUND: Adults with chronic critical illness (CCI) frequently experience a terminal trajectory but receive varying degrees of palliation and end-of-life care (EOLC) in intensive care units (ICUs). Why palliation (over curative treatment) is not augmented earlier for patients with CCI in ICU is not well understood. PURPOSE: To identify the social structures that contribute to timely, context-dependent decisions for transition from acute care to EOLC for patients with CCI and their families. METHODS: We conducted a meta-synthesis of qualitative and/or mixed-method studies that recruited adults with CCI, their families or close friends, and/or health-care providers (HCPs) in an ICU environment. RESULTS: Five studies reported data from 83 patients, 109 family members, and 57 HCPs across 5 institutions in Canada and the United States. Overall, we found that morally ambiguous social expectations of treatment tended to lock in HCPs to focus on prescriptive work of preserving life, despite pathways that could "open" access to augmenting palliation and EOLC. This process limited space for families' reflexivity and reappraisal of CCI as a phase liminal to active dying. Notably, EOLC mechanisms were informal and less visible. CONCLUSION: The management of dying is one of the central tenets of ICU care. Our findings suggest that patients and families need help in negotiating meanings of this situation and in using mechanisms that allow reappraisal and permit understanding of CCI as a phase liminal to dying. Moreover, these mechanisms may paradoxically reduce the ambiguity of patients' future, allowing them to live more fully in the present.

Experts Consensus Recommendations for the Management of Calcium Channel Blocker Poisoning in Adults.

OBJECTIVE: To provide a management approach for adults with calcium channel blocker poisoning. DATA SOURCES, STUDY SELECTION, AND DATA EXTRACTION: Following the Appraisal of Guidelines for Research & Evaluation II instrument, initial voting statements were constructed based on summaries outlining the evidence, risks, and benefits. DATA SYNTHESIS: We recommend 1) for asymptomatic patients, observation and consideration of decontamination following a potentially toxic calcium channel blocker ingestion (1D); 2) as first-line therapies (prioritized based on desired effect), IV calcium (1D), high-dose insulin therapy (1D-2D), and norepinephrine and/or epinephrine (1D). We also suggest dobutamine or epinephrine in the presence of cardiogenic shock (2D) and atropine in the presence of symptomatic bradycardia or conduction disturbance (2D); 3) in patients refractory to the first-line treatments, we suggest incremental doses of high-dose insulin therapy if myocardial dysfunction is present (2D), IV lipid-emulsion therapy (2D), and using a pacemaker in the presence of unstable bradycardia or high-grade arteriovenous block without significant alteration in cardiac inotropism (2D); 4) in patients with refractory shock or who are periarrest, we recommend incremental doses of high-dose insulin (1D) and IV lipid-emulsion therapy (1D) if not already tried. We suggest venoarterial extracorporeal membrane oxygenation, if available, when refractory shock has a significant cardiogenic component (2D), and using pacemaker in the presence of unstable bradycardia or high-grade arteriovenous block in the absence of myocardial dysfunction (2D) if not already tried; 5) in patients with cardiac arrest, we recommend IV calcium in addition to the standard advanced cardiac life-support (1D), lipid-emulsion therapy (1D), and we suggest venoarterial extracorporeal membrane oxygenation if available (2D). CONCLUSION: We offer recommendations for the stepwise management of calcium channel blocker toxicity. For all interventions, the level of evidence was very low.

A mixed-methods systematic review protocol to examine the use of physical restraint with critically ill adults and strategies for minimizing their use.

BACKGROUND: Critically ill patients frequently experience severe agitation placing them at risk of harm. Physical restraint is common in intensive care units (ICUs) for clinician concerns about safety. However, physical restraint may not prevent medical device removal and has been associated with negative physical and psychological consequences. While professional society guidelines, legislation, and accreditation standards recommend physical restraint minimization, guidelines for critically ill patients are over a decade old, with recommendations that are non-specific. Our systematic review will synthesize evidence on physical restraint in critically ill adults with the primary objective of identifying effective minimization strategies. METHODS: Two authors will independently search from inception to July 2016 the following: Ovid MEDLINE, CINAHL, Embase, Web of Science, Cochrane Library, PROSPERO, Joanna Briggs Institute, grey literature, professional society websites, and the International Clinical Trials Registry Platform. We will include quantitative and qualitative study designs, clinical practice guidelines, policy documents, and professional society recommendations relevant to physical restraint of critically ill adults. Authors will independently perform data extraction in duplicate and complete risk of bias and quality assessment using recommended tools. We will assess evidence quality for quantitative studies using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach and for qualitative studies using the Confidence in the Evidence from Reviews of Qualitative Research (CERQual) guidelines. Outcomes of interest include (1) efficacy/effectiveness of physical restraint minimization strategies; (2) adverse events (unintentional device removal, psychological impact, physical injury) and associated benefits including harm prevention; (3) ICU outcomes (ventilation duration, length of stay, and mortality); (4) prevalence, incidence, patterns of use including patient and treatment characteristics and chemical restraint; (5) barriers and facilitators to minimization; (6) patient, family, and healthcare professional perspectives; (7) professional society-endorsed recommendations; and (8) evidence gaps and research priorities. DISCUSSION: We will use our systematic review findings to produce updated guidelines on physical restraint use for critically ill adults and to develop a professional society-endorsed position statement. This will foster patient and clinician safety by providing clinicians, administrators, and policy makers with a tool to promote minimal and safe use of physical restraint for critically ill adults.

One-Year Outcomes in Caregivers of Critically Ill Patients.

BACKGROUND: Few resources are available to support caregivers of patients who have survived critical illness; consequently, the caregivers' own health may suffer. We studied caregiver and patient characteristics to determine which characteristics were associated with caregivers' health outcomes during the first year after patient discharge from an intensive care unit (ICU). METHODS: We prospectively enrolled 280 caregivers of patients who had received 7 or more days of mechanical ventilation in an ICU. Using hospital data and self-administered questionnaires, we collected information on caregiver and patient characteristics, including caregiver depressive symptoms, psychological well-being, health-related quality of life, sense of control over life, and effect of providing care on other activities. Assessments occurred 7 days and 3, 6, and 12 months after ICU discharge. RESULTS: The caregivers' mean age was 53 years, 70% were women, and 61% were caring for a spouse. A large percentage of caregivers (67% initially and 43% at 1 year) reported high levels of depressive symptoms. Depressive symptoms decreased at least partially with time in 84% of the caregivers but did not in 16%. Variables that were significantly associated with worse mental health outcomes in caregivers were younger age, greater effect of patient care on other activities, less social support, less sense of control over life, and less personal growth. No patient variables were consistently associated with caregiver outcomes over time. CONCLUSIONS: In this study, most caregivers of critically ill patients reported high levels of depressive symptoms, which commonly persisted up to 1 year and did not decrease in some caregivers.

Ethnographic Investigation of Oral Care in the Intensive Care Unit.

BACKGROUND: Oral care plays a clear and important role in the prevention of ventilator-associated pneumonia. However, few studies have explored the actual work of oral care by nurses in the intensive care unit. OBJECTIVE: To explore intensive care nurses' knowledge of and experiences with the delivery of oral care to reveal less visible aspects of this work. METHODS: In an institutional ethnography, go-along and semistructured interview methods were used to explore the oral care practices and perspectives of 12 bedside nurses and 12 interprofessional (intensivist, allied health, and management) participants in an intensive care unit at a large urban teaching hospital in Ontario, Canada. RESULTS: Nurses described how obstacles frequently inhibited the delivery of oral care. Technical barriers included oral crowding with tubes and aversive responses by patients, such as biting. Contextual impediments to oral care included time constraints, lack of training, and limited opportunities for interprofessional collaboration. A key discovery was the presence of an informal unit-based nursing curriculum, whereby nurses acquired strategies to overcome barriers to oral care. Although the nurses did extensive problem solving in providing oral care, the interprofessional participants had limited knowledge of how oral care was accomplished. CONCLUSION: These data suggest the complexity of performing oral care in intensive care is underestimated and perhaps undervalued. Future research is needed to address technical and contextual barriers to optimize current guideline expectations for the provision of regular and effective oral care.

Understanding Early Decisions to Withdraw Life-Sustaining Therapy in Cardiac Arrest Survivors. A Qualitative Investigation.

RATIONALE: Early withdrawal of life-sustaining therapy contributes to the majority of deaths following out-of-hospital cardiac arrest (OHCA), despite current recommendations for delayed neurological prognostication (≥72 h) after treatment with targeted temperature management. Little is known about clinicians' experiences of early withdrawal of life support decisions in patients with OHCA. OBJECTIVES: To explore clinicians' experiences and perceptions of early withdrawal of life support decisions and barriers to guideline-concordant neurological prognostication in comatose survivors of OHCA treated with targeted temperature management. METHODS: We conducted qualitative interviews with intensive care unit (ICU) physicians and nurses following withdrawal of life support in comatose patients with OHCA treated with targeted temperature management. The study was carried out across 18 academic and community hospitals participating in a multicenter, stepped-wedge, cluster-randomized controlled trial designed to improve quality-of-care processes for patients after OHCA in Ontario, Canada. We used a focused thematic analysis to capture barriers to guideline-concordant neurological prognostication and used these barriers to identify potentially modifiable issues. MEASUREMENTS AND MAIN RESULTS: The core thematic finding was a high emotional burden of ICU family-team communication in which strong feelings inhibited information transfer and delayed decision making following OHCA. Four subthemes describing sources of communication strain were identified: (1) requests from family members to provide early outcome predictions, (2) incomplete family comprehension of critical care, (3) family requests for early withdrawal of life support based on their understanding of patients' preferences and values, and (4) family-team communication gaps related to prognostic uncertainty. Participants worried that gaps in timely and clear prognostic information contributed to surrogates' perceptions of a poor outcome and to inappropriately early decisions to withdraw life support. CONCLUSIONS: Family-team communication difficulties may be an underestimated factor leading to early withdrawal of life support in ICUs for individuals who initially survive OHCA.
