RESUMO

BACKGROUND: Acute kidney injury is common in critically ill patients, many of whom receive renal-replacement therapy. However, the most effective timing for the initiation of such therapy remains uncertain. METHODS: We conducted a multinational, randomized, controlled trial involving critically ill patients with severe acute kidney injury. Patients were randomly assigned to receive an accelerated strategy of renal-replacement therapy (in which therapy was initiated within 12 hours after the patient had met eligibility criteria) or a standard strategy (in which renal-replacement therapy was discouraged unless conventional indications developed or acute kidney injury persisted for >72 hours). The primary outcome was death from any cause at 90 days. RESULTS: Of the 3019 patients who had undergone randomization, 2927 (97.0%) were included in the modified intention-to-treat analysis (1465 in the accelerated-strategy group and 1462 in the standard-strategy group). Of these patients, renal-replacement therapy was performed in 1418 (96.8%) in the accelerated-strategy group and in 903 (61.8%) in the standard-strategy group. At 90 days, death had occurred in 643 patients (43.9%) in the accelerated-strategy group and in 639 (43.7%) in the standard-strategy group (relative risk, 1.00; 95% confidence interval [CI], 0.93 to 1.09; P = 0.92). Among survivors at 90 days, continued dependence on renal-replacement therapy was confirmed in 85 of 814 patients (10.4%) in the accelerated-strategy group and in 49 of 815 patients (6.0%) in the standard-strategy group (relative risk, 1.74; 95% CI, 1.24 to 2.43). Adverse events occurred in 346 of 1503 patients (23.0%) in the accelerated-strategy group and in 245 of 1489 patients (16.5%) in the standard-strategy group (P<0.001). CONCLUSIONS: Among critically ill patients with acute kidney injury, an accelerated renal-replacement strategy was not associated with a lower risk of death at 90 days than a standard strategy.

RESUMO

INTRODUCTION: This is a rapid review of the published evidence on the effectiveness of interventions for mitigating workplace violence against staff in hospital emergency departments. Focused on the specific needs of an urban emergency department in Canada, this project sought to address the question, "What interventions have evidence regarding effectiveness for addressing workplace patient/visitor violence toward staff in the emergency department?" METHODS: Following Cochrane Rapid Review methods, 5 electronic databases (MEDLINE via PubMed, Cochrane CENTRAL, Embase, PsycINFO, CINAHL) and Google Scholar were searched in April 2022 for intervention studies to reduce or mitigate workplace violence against staff in hospital emergency departments. Critical appraisal was conducted using Joanna Briggs Institute tools. Key study findings were synthesized narratively. RESULTS: Twenty-four studies (21 individual studies, 3 reviews) were included in this rapid review. A variety of strategies for reducing and mitigating workplace violence were identified and categorized as single or multicomponent interventions. Although most studies reported positive outcomes on workplace violence, the articles offered limited descriptions of the interventions and/or lacked robust data to demonstrate effectiveness. Insights from across the studies offer knowledge users information to support the development of comprehensive strategies to reduce workplace violence. DISCUSSION: Despite a large body of literature on workplace violence, there is little guidance on effective strategies to mitigate workplace violence in emergency departments. Evidence suggests that multicomponent approaches targeting staff, patients/visitors, and the emergency department environment are essential to addressing and mitigating workplace violence. More research is needed that provides robust evidence on effective violence prevention interventions.

RESUMO

BACKGROUND: Reverse triggering is a delayed asynchronous contraction of the diaphragm triggered by passive insufflation by the ventilator in sedated mechanically ventilated patients. The incidence of reverse triggering is unknown. This study aimed at determining the incidence of reverse triggering in critically ill patients under controlled ventilation. METHODS: In this ancillary study, patients were continuously monitored with a catheter measuring the electrical activity of the diaphragm. A method for automatic detection of reverse triggering using electrical activity of the diaphragm was developed in a derivation sample and validated in a subsequent sample. The authors assessed the predictive value of the software. In 39 recently intubated patients under assist-control ventilation, a 1-h recording obtained 24 h after intubation was used to determine the primary outcome of the study. The authors also compared patients' demographics, sedation depth, ventilation settings, and time to transition to assisted ventilation or extubation according to the median rate of reverse triggering. RESULTS: The positive and negative predictive value of the software for detecting reverse triggering were 0.74 (95% CI, 0.67 to 0.81) and 0.97 (95% CI, 0.96 to 0.98). Using a threshold of 1 µV of electrical activity to define diaphragm activation, median reverse triggering rate was 8% (range, 0.1 to 75), with 44% (17 of 39) of patients having greater than or equal to 10% of breaths with reverse triggering. Using a threshold of 3 µV, 26% (10 of 39) of patients had greater than or equal to 10% reverse triggering. Patients with more reverse triggering were more likely to progress to an assisted mode or extubation within the following 24 h (12 of 39 [68%]) vs. 7 of 20 [35%]; P = 0.039). CONCLUSIONS: Reverse triggering detection based on electrical activity of the diaphragm suggests that this asynchrony is highly prevalent at 24 h after intubation under assist-control ventilation. Reverse triggering seems to occur during the transition phase between deep sedation and the onset of patient triggering.

RESUMO

PURPOSE: The 3 Wishes Project (3WP) promotes holistic end-of-life care in the intensive care unit (ICU) to honor dying patients, support families, and encourage clinician compassion. Organ donation is a wish that is sometimes made by, or on behalf of, critically ill patients. Our objective was to describe the interface between the 3WP and organ donation as experienced by families, clinicians, and organ donation coordinators. METHODS: In a multicenter evaluation of the 3WP in 4 Canadian ICUs, we conducted a thematic analysis of transcripts from interviews and focus groups with clinicians, organ donation coordinators, and families of dying or died patients for whom donation was considered. RESULTS: We analyzed transcripts from 26 interviews and 2 focus groups with 18 family members, 17 clinicians, and 6 organ donation coordinators. The central theme describes the mutual goals of the 3WP and organ donation-emphasizing personhood and agency across the temporal continuum of care. During family decision-making, conversations encouraged by the 3WP can facilitate preliminary discussions about donation. During preparation for donation, memory-making activities supported by the 3WP redirect focus toward personhood. During postmortem family care, the 3WP supports families, including when donation is unsuccessful, and highlights aspirational pursuits of donation while encouraging reflections on other fulfilled wishes. CONCLUSIONS: Organ donation and the 3WP provide complementary opportunities to engage in value-based conversations during the dying process. The shared values of these programs may help to incorporate organ donation and death into a person's life narrative and incorporate new life into a person's death narrative.

RESUMO

BACKGROUND: Inability to communicate in a manner that can be understood causes extreme distress for people requiring an artificial airway and has implications for care quality and patient safety. Options for aided communication include non-vocal, speech-generating, and voice-enabling aids. OBJECTIVES: To assess effectiveness of communication aids for people requiring an artificial airway (endotracheal or tracheostomy tube), defined as the proportion of people able to: use a non-vocal communication aid to communicate at least one symptom, need, or preference; or use a voice-enabling communication aid to phonate to produce at least one intelligible word. To assess time to communication/phonation; perceptions of communication; communication quality/success; quality of life; psychological distress; length of stay and costs; and adverse events. SEARCH METHODS: We searched the Cochrane Library (Wiley version), MEDLINE (OvidSP), Embase (OvidSP), three other databases, and grey literature from inception to 30 July 2020. SELECTION CRITERIA: We included randomised controlled trials (RCTs), quasi-RCTs, cluster-RCTs, controlled non-randomised parallel group, and before-after studies evaluating communication aids used in adults with an artificial airway. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures recommended by Cochrane. Two review authors independently performed data extraction and assessment of risk of bias. MAIN RESULTS: We included 11 studies (1931 participants) conducted in intensive care units (ICUs). Eight evaluated non-vocal communication aids and three voice-enabling aids. Usual care was the comparator for all. For six studies, this comprised no aid; usual care in the remaining five studies comprised use of various communication aids. Overall, our confidence in results regarding effectiveness of communication interventions was very low due to imprecision, measurement heterogeneity, inconsistency in results, and most studies at high or unclear risk of bias across multiple domains. No non-vocal aid studies reported our primary outcome. We are uncertain of the effects of early use of a voice-enabling aid compared to routine use on ability to phonate at least one intelligible word (risk ratio (RR) 3.03, 95% confidence interval (CI) 0.18 to 50.08; 2 studies; very low-certainty evidence). Compared to usual care without aids, we are uncertain about effects of a non-vocal aid (communication board) on patient satisfaction (standardised mean difference (SMD) 2.92, 95% CI 1.52 to 4.33; 4 studies; very low-certainty evidence). No studies of non-vocal aids reported quality of life. Low-certainty evidence from two studies suggests early use of a voice-enabling aid may have no effect on quality of life (MD 2.27, 95% CI -7.21 to 11.75). Conceptual differences in measures of psychological distress precluded data pooling; however, intervention arm participants reported less distress suggesting there might be benefit, but our certainty in the evidence is very low. Low-certainty evidence suggest voice-enabling aids have little or no effect on ICU length of stay; we were unable to determine effects of non-vocal aids. Three studies reported different adverse events (physical restraint use, bleeding following tracheostomy, and respiratory parameters indicating respiratory decompensation). Adverse event rates were similar between arms in all three studies. However, uncertainty remains as to any harm associated with communication aids. AUTHORS' CONCLUSIONS: Due to a lack of high-quality studies, imprecision, inconsistency of results, and measurement heterogeneity,  the evidence provides insufficient information to guide practice as to which communication aid is more appropriate and when to use them. Understanding effectiveness of communication aids would benefit from development of a core outcome measurement set.

RESUMO

BACKGROUND: The 3 Wishes Project (3WP) is an end-of-life program that honors the dignity of dying patients by fostering meaningful connections among patients, families, and clinicians. Since 2013, it has become embedded in the culture of end-of-life care in over 20 ICUs across North America. The purpose of the current study is to describe the variation in implementation of 3WP across sites, in order to ascertain which factors facilitated multicenter implementation, which factors remain consistent across sites, and which may be adapted to suit local needs. METHODS: Using the methodology of qualitative description, we collected interview and focus group data from 85 clinicians who participated in the successful initiation and sustainment of 3WP in 9 ICUs. We describe the transition between different models of 3WP implementation, from core clinical program to the incorporation of various research activities. We describe various sources of financial and in-kind resources accessed to support the program. RESULTS: Beyond sharing a common goal of improving end-of-life care, sites varied considerably in organizational context, staff complement, and resources. Despite these differences, the program was successfully implemented at each site and eventually evolved from a clinical or research intervention to a general approach to end-of-life care. Key to this success was flexibility and the empowerment of frontline staff to tailor the program to address identified needs with available resources. This adaptability was fueled by cross-pollination of ideas within and outside of each site, resulting in the establishment of a network of like-minded individuals with a shared purpose. CONCLUSIONS: The successful initiation and sustainment of 3WP relied on local adaptations to suit organizational needs and resources. The semi-structured nature of the program facilitated these adaptations, encouraged creative and important ways of relating within local clinical cultures, and reinforced the main tenet of the program: meaningful human connection at the end of life. Local adaptations also encouraged a team approach to care, supplementing the typical patient-clinician dyad by explicitly empowering the healthcare team to collectively recognize and respond to the needs of dying patients, families, and each other.

RESUMO

OBJECTIVE: To characterize ICU nurses' research experience, work environments, and attitudes toward clinical research in critically ill adults and children. DESIGN: Cross-sectional survey. SETTING: Eight (seven adult and one pediatric) academic ICUs affiliated with the Canadian Critical Care Trials Group. PARTICIPANTS: Four hundred eighty-two ICU nurses. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Response rate was 56%. Most participants had over 6 years of ICU experience (61%) and held a baccalaureate nursing degree (57%). Most participants (63%) had provided care for patients receiving research study procedures more than five times in the past 12 months and agreed that research leads to improved care for the critically ill (78%) and eligible patients should be approached for research participation (78%). Few perceived practicalities of nursing care are considered in study design (20%); 41% agreed that research studies increases nursing workload. Few participants reported receiving adequate information about study progress (24%) or findings (26%). Principal factor analysis identified three factors each in the environmental and attitudinal domains. Linear regression models demonstrated that positive relationships between researchers and clinicians were associated with favorable perceptions of research impact on nursing care (p < 0.001), ICU research acceptability (p < 0.001), and nursing engagement in research (p < 0.05). Nurses with more formal education reported more favorable attitudes toward nursing engagement in research (p < 0.01) and research acceptability (p < 0.01). Lack of experience in study protocol development and/or data analysis was associated with less favorable attitudes about nursing engagement in research (p < 0.01) and impact of research on nursing care (p < 0.01). CONCLUSION: In these research-intensive ICUs, nurses frequently care for research participants and believe ICU research is important. Inclusion of nurses in study protocol development, improved communication of study progress and findings, and investigation of research-related nursing workload are warranted. Such interventions will support intervention fidelity and data reliability during study conduct and translation of evidence into practice on study completion.

RESUMO

OBJECTIVE: To evaluate whether a Post-Arrest Consult Team improved care and outcomes for patients with out-of-hospital cardiac arrest. DESIGN: Prospective cohort study of Post-Arrest Consult Team implementation at two hospitals, with concurrent controls from 27 others. SETTING: Twenty-nine hospitals within the Strategies for Post-Arrest Care Network of Southern Ontario, Canada. PATIENTS: We included comatose adult nontraumatic out-of-hospital cardiac arrest patients surviving more than or equal to 6 hours after emergency department arrival who had no contraindications to targeted temperature management. INTERVENTION: The Post-Arrest Consult Team was an advisory consult service to improve 1) targeted temperature management, 2) assessment for percutaneous coronary intervention, 3) electrophysiology assessment, and 4) appropriately delayed neuroprognostication. MEASUREMENTS AND MAIN RESULTS: We used generalized linear mixed models to explore the association between Post-Arrest Consult Team implementation and performance of targeted processes. We included 1,006 patients. The Post-Arrest Consult Team was associated with a significant reduction over time in rates of withdrawal of life-sustaining therapy within 72 hours of emergency department arrival on the basis of predictions of poor neurologic prognosis (ratio of odds ratios, 0.13; 95% CI, 0.02-0.98). Post-Arrest Consult Team was not associated with improved successful targeted temperature management (ratio of odds ratios, 0.91; 95% CI, 0.31-2.65), undergoing angiography (ratio of odds ratios, 1.91; 95% CI, 0.17-21.04), receiving electrophysiology consultation (ratio of odds ratios, 0.93; 95% CI, 0.11-8.16), or functional survival (ratio of odds ratios, 0.75; 95% CI, 0.19-2.94). CONCLUSIONS: Implementation of a Post-Arrest Consult Team reduced premature withdrawal of life-sustaining therapy but did not improve rates of successful targeted temperature management, coronary angiography, formal electrophysiology assessments, or functional survival for comatose patients after out-of-hospital cardiac arrest.

RESUMO

OBJECTIVE: Antimicrobial stewardship is a process designed to optimize antimicrobial therapy by ensuring patients get the right antimicrobials at the right dose and at the right time. Antimicrobial stewardship programs (ASPs) are increasingly being implemented in health care institutions, are required by some accreditation bodies, and have the potential for maximum impact in intensive care units (ICUs). We administered a survey to critical care physicians across Canada to better understand their knowledge, attitudes, and perceptions on the utility of ASPs in improving patient care. DESIGN, SETTING, AND PATIENTS: We distributed a Web-based survey to physicians who attend in Canadian ICUs. Respondents were identified through the membership lists of multiple critical care organizations. Content validity, utility, clarity, and test-retest reliability were evaluated prior to distribution. Survey items assessed ASP knowledge, attitudes, and experiences. Attitudes toward ASPs were assessed on a 5-point Likert-type scale. MEASUREMENTS AND MAIN RESULTS: The survey was completed by 185 physicians, with a response rate of 29% (n = 185/634) for all physicians contacted. A majority (74%) of respondents reported that there was at least 1 component of an ASP at their institution. Most (86%) respondents agreed or strongly agreed that the patients in their ICU benefit from an ASP, with 81% reporting the ASP increases their knowledge of appropriate antimicrobial use in the ICU setting. Only 11% of respondents reported they felt that time spent interacting with the ASP team was an inefficient use of their time, and only 7% expressed concern that the ASP negatively affected their autonomy. CONCLUSION: Based on our survey results, Canadian intensivists are supportive of antimicrobial stewardship in ICUs and feel that ASPs provide a valuable service to both patients and clinicians.

RESUMO

In patients with severe acute kidney injury (AKI) but no urgent indication for renal replacement therapy (RRT), the optimal time to initiate RRT remains controversial. While starting RRT preemptively may have benefits, this may expose patients to unnecessary RRT. To study this, we conducted a 12-center open-label pilot trial of critically ill adults with volume replete severe AKI. Patients were randomized to accelerated (12 h or less from eligibility) or standard RRT initiation. Outcomes were adherence to protocol-defined time windows for RRT initiation (primary), proportion of eligible patients enrolled, follow-up to 90 days, and safety in 101 fully eligible patients (57 with sepsis) with a mean age of 63 years. Median serum creatinine and urine output at enrollment were 268 micromoles/l and 356 ml per 24 h, respectively. In the accelerated arm, all patients commenced RRT and 45/48 did so within 12 h from eligibility (median 7.4 h). In the standard arm, 33 patients started RRT at a median of 31.6 h from eligibility, of which 19 did not receive RRT (6 died and 13 recovered kidney function). Clinical outcomes were available for all patients at 90 days following enrollment, with mortality 38% in the accelerated and 37% in the standard arm. Two surviving patients, both randomized to standard RRT initiation, were still RRT dependent at day 90. No safety signal was evident in either arm. Our findings can inform the design of a large-scale effectiveness randomized control trial.

RESUMO

BACKGROUND: There is controversy regarding the optimal renal-replacement therapy (RRT) modality for critically ill patients with acute kidney injury (AKI). METHODS: We conducted a secondary analysis of the STandard versus Accelerated Renal Replacement Therapy in Acute Kidney Injury (STARRT-AKI) trial to compare outcomes among patients who initiated RRT with either continuous renal replacement therapy (CRRT) or intermittent hemodialysis (IHD). We generated a propensity score for the likelihood of receiving CRRT and used inverse probability of treatment with overlap-weighting to address baseline inter-group differences. The primary outcome was a composite of death or RRT dependence at 90-days after randomization. RESULTS: We identified 1590 trial participants who initially received CRRT and 606 who initially received IHD. The composite outcome of death or RRT dependence at 90-days occurred in 823 (51.8%) patients who commenced CRRT and 329 (54.3%) patients who commenced IHD (unadjusted odds ratio (OR) 0.90; 95% confidence interval (CI) 0.75-1.09). After balancing baseline characteristics with overlap weighting, initial receipt of CRRT was associated with a lower risk of death or RRT dependence at 90-days compared with initial receipt of IHD (OR 0.81; 95% CI 0.66-0.99). This association was predominantly driven by a lower risk of RRT dependence at 90-days (OR 0.61; 95% CI 0.39-0.94). CONCLUSIONS: In critically ill patients with severe AKI, initiation of CRRT, as compared to IHD, was associated with a significant reduction in the composite outcome of death or RRT dependence at 90-days.

RESUMO

OBJECTIVE: To determine whether catheter-associated urinary tract infections are associated with increased morbidity and mortality in critically ill patients. DATA SOURCES: MEDLINE, HealthStar, EMBASE, and CINAHL databases from inception to June 2010 and bibliographies of included studies without language restriction. STUDY SELECTION: Studies reporting mortality or morbidity in adult intensive care unit patients with and without catheter-associated urinary tract infections. DATA EXTRACTION: Two authors independently selected studies and extracted data on study methodology, quality, and patient outcomes using a standardized form. Meta-analyses were performed using random-effects models. DATA SYNTHESIS: Of 720 citations, 11 studies enrolling 2,745 patients with and 60,719 patients without catheter-associated urinary tract infections met inclusion criteria. Catheter-associated urinary tract infection was associated with a significant increase in mortality (odds ratio [OR], 1.99; 95% confidence interval [CI], 1.72-2.31; p < .00001; I2 = 54%; eight studies; 62,063 patients) and length of stay in the intensive care unit (weighted mean difference of + 12 days; 95% CI, 9-15; p < .00001; I2 = 96%; seven studies; 13,011 patients) and hospital (mean difference + 21 days; 95% CI, 11-32; p < .0001; I2 = 98%; five studies; 10,183 patients). Restricting the analysis only to the two studies that adjusted for other outcome predictors, catheter-associated urinary tract infections were not associated with an increase in mortality (OR, 0.97; 95% CI, 0.82-1.16; p = .77; I2 = 0%; two studies; 5,626 patients). Although both studies individually demonstrated significantly increased intensive care unit length of stay after adjustment, pooled data showed that catheter-associated urinary tract infections were associated with a significant increase in intensive care unit length of stay using only a fixed effects model (mean difference + 2.6 days; 95% CI, 2.3-3.0; p < .00001) and not a random effects model (mean difference + 8 days; 95% CI, -13 to +28 days; p = .46) due to the high degree of heterogeneity for this outcome between the two studies (I2 = 99.6%) which results in a larger CI. CONCLUSIONS: Catheter-associated urinary tract infection is associated with significantly increased mortality and length of stay in unmatched studies. Increased mortality and possibly increased length of stay appear to be consequences of confounding by unmeasured variables. These findings highlight the importance of evaluating risks and benefits of commonly used treatments such as antibiotics to manage catheter-associated urinary tract infection.

RESUMO

PURPOSE: Oral chlorhexidine is used widely for mechanically ventilated patients to prevent pneumonia, but recent studies show an association with excess mortality. We examined whether de-adoption of chlorhexidine and parallel implementation of a standardized oral care bundle reduces intensive care unit (ICU) mortality in mechanically ventilated patients. METHODS: A stepped wedge cluster-randomized controlled trial with concurrent process evaluation in 6 ICUs in Toronto, Canada. Clusters were randomized to de-adopt chlorhexidine and implement a standardized oral care bundle at 2-month intervals. The primary outcome was ICU mortality. Secondary outcomes were time to infection-related ventilator-associated complications (IVACs), oral procedural pain and oral health dysfunction. An exploratory post hoc analysis examined time to extubation in survivors. RESULTS: A total of 3260 patients were enrolled; 1560 control, 1700 intervention. ICU mortality for the intervention and control periods were 399 (23.5%) and 330 (21.2%), respectively (adjusted odds ratio [aOR], 1.13; 95% confidence interval [CI] 0.82 to 1.54; P = 0.46). Time to IVACs (adjusted hazard ratio [aHR], 1.06; 95% CI 0.44 to 2.57; P = 0.90), time to extubation (aHR 1.03; 95% CI 0.85 to 1.23; P = 0.79) (survivors) and oral procedural pain (aOR, 0.62; 95% CI 0.34 to 1.10; P = 0.10) were similar between control and intervention periods. However, oral health dysfunction scores (- 0.96; 95% CI - 1.75 to - 0.17; P = 0.02) improved in the intervention period. CONCLUSION: Among mechanically ventilated ICU patients, no benefit was observed for de-adoption of chlorhexidine and implementation of an oral care bundle on ICU mortality, IVACs, oral procedural pain, or time to extubation. The intervention may improve oral health.

RESUMO

BACKGROUND: Most intensive care patients require substitute decision makers (SDMs) to make decisions. The SDMs may prefer an active, shared, or passive decision-making role. Role incongruence is when preferred and actual roles differ. OBJECTIVE: To evaluate the impact of decision-making role preferences and role incongruence on psychological distress symptoms in SDMs. METHODS: A multicenter, interviewer-administered survey was conducted among SDMs of critically ill adults. The Control Preferences Scale was used to evaluate role preferences. Psychological distress was defined as anxiety, depression, or posttraumatic stress symptoms with predefined cut points on the Hospital Anxiety and Depression Scale (score > 10 on the anxiety or the depression subscale) and Impact of Events Scale (score > 30). RESULTS: One hundred eighty SDMs were recruited; 64% responded. Most were white (71%) and female (65%); 46% were spouses. Role preferences varied: active, 24%; shared, 44%; and passive, 31%. Almost half (49%) reported incongruence. Symptom prevalence was 50% for posttraumatic stress, 32% for anxiety, and 16% for depression. Most (56%) reported some psychological distress. In multivariable logistic regression, the composite outcome of psychological distress was independently associated with patient death (odds ratio, 2.95; 95% CI, 1.08-8.02; P = .03), female sex of SDM (odds ratio, 2.96; 95% CI, 1.49-5.89; P = .002), and incongruence (odds ratio, 3.26; 95% CI, 1.67-6.36; P < .001). CONCLUSIONS: Adverse psychological symptoms are prevalent in SDMs of critically ill patients and are related to role incongruence.

RESUMO

BACKGROUND: A recent randomized trial of bereaved family members of patients who died in an intensive care unit identified symptoms of depression and posttraumatic stress in recipients of semistructured condolence letters. OBJECTIVES: To explore family member and clinician experiences with receiving or sending handwritten sympathy cards upon the death of patients involved in a personalized end-of-life intervention, the 3 Wishes Project. METHODS: Interviews and focus groups were held with 171 family members and 222 clinicians at 4 centers to discuss their experiences with the 3 Wishes Project. Interview transcripts were searched to identify participants who discussed sympathy cards. Data related to sympathy cards were independently coded by 2 investigators through conventional content analysis. RESULTS: Sympathy cards were discussed during 32 interviews (by 25 family members of 21 patients and by 11 clinicians) and 2 focus groups (8 other clinicians). Family members reported that personalized sympathy cards were a welcome surprise; they experienced them as a heartfelt act of compassion. Clinicians viewed cards as an opportunity to express shared humanity with families, reminding them that they and their loved one were not forgotten. Signing cards allowed clinicians to reminisce individually and collectively with colleagues. Family members and clinicians experienced sympathy cards as a meaningful continuation of care after a patient's death. CONCLUSIONS: Inviting clinicians who cared for deceased patients to offer personalized, handwritten condolences to bereaved family members may cultivate sincere and individualized expressions of sympathy that bereaved families appreciate after the death of patients involved in the 3 Wishes Project.

RESUMO

CONTEXT: Keepsakes are a relatively unexplored form of bereavement support that is frequently provided as part of the 3 Wishes Project (3WP). The 3WP is a palliative care intervention in which individualized wishes are implemented in the adult intensive care unit for dying patients and their families. OBJECTIVES: We aimed to characterize and enumerate the keepsakes that were created as part of the 3WP and to understand their value from the perspective of bereaved family members. METHODS: We performed a secondary analysis of family interviews during a multicenter study on the 3WP and characterized all wishes that involved keepsakes. Sixty interviews with family members regarding the 3WP were reanalyzed using qualitative analysis to identify substantive themes related to keepsakes. RESULTS: Of 730 patients, 345 (47%) received keepsakes as part of their participation in 3WP. Most keepsakes were either tangible items that served as reminders of the patient's presence (thumbprints and locks of hair) or technology-assisted items (photographs and word clouds). The median cost per keepsake wish was $8.50 (interquartile range $2.00-$25.00). Qualitative analysis revealed two major themes: keepsakes are tangible items that are highly valued by family members; and the creation of the keepsake with clinical staff is valued and viewed as a gesture of compassion. CONCLUSION: Keepsakes are common wishes that clinicians in the intensive care unit are able to provide and sometimes cocreate with families when patients are dying. Both the offering to create the keepsake and receipt of the final product are perceived by family members as helpful.

RESUMO

BACKGROUND: Routine application of chlorhexidine oral rinse is recommended to reduce risk of ventilator-associated pneumonia (VAP) in mechanically ventilated patients. Recent reappraisal of the evidence from two meta-analyses suggests chlorhexidine may cause excess mortality in non-cardiac surgery patients and does not reduce VAP. Mechanisms for possible excess mortality are unclear. The CHORAL study will evaluate the impact of de-adopting chlorhexidine and implementing an oral care bundle (excluding chlorhexidine) on mortality, infection-related ventilator-associated complications (IVACs), and oral health status. METHODS: The CHORAL study is a stepped wedge, cluster randomized controlled trial in six academic intensive care units (ICUs) in Toronto, Canada. Clusters (ICU) will be randomly allocated to six sequential steps over a 14-month period to de-adopt oral chlorhexidine and implement a standardized oral care bundle (oral assessment, tooth brushing, moisturization, and secretion removal). On study commencement, all clusters begin with a control period in which the standard of care is oral chlorhexidine. Clusters then begin crossover from control to intervention every 2 months according to the randomization schedule. Participants include all mechanically ventilated adults eligible to receive the standardized oral care bundle. The primary outcome is ICU mortality; secondary outcomes are IVACs and oral health status. We will determine demographics, antibiotic usage, mortality, and IVAC rates from a validated local ICU clinical registry. With six clusters and 50 ventilated patients on average each month per cluster, we estimate that 4200 patients provide 80% power after accounting for intracluster correlation to detect an absolute reduction in mortality of 5.5%. We will analyze our primary outcome of mortality using a generalized linear mixed model adjusting for time to account for secular trends. We will conduct a process evaluation to determine intervention fidelity and to inform interpretation of the trial results. DISCUSSION: The CHORAL study will inform understanding of the effectiveness of de-adoption of oral chlorhexidine and implementation of a standardized oral care bundle for decreasing ICU mortality and IVAC rates while improving oral health status. Our process evaluation will inform clinicians and decision makers about intervention delivery to support future de-adoption if justified by trial results.
