Purpose: Persistent critical illness has been described as a subtype of chronic critical illness, characterized as a transition after ICU admission where primary diagnosis and illness acuity are no better at predicting outcome than pre-hospital characteristics. Herein we describe the occurrence and outcomes associated with persistent critical illness in a large Canadian health region.Methods: In this multi-center observational cohort study, all patients aged older than 14 years admitted to 12 ICUs in Alberta, Canada, between June 2012 and December 2014 were included. Primary outcome was in-hospital mortality. Predictors at ICU admission were separated into: (1) antecedent characteristics component (e.g., demographics, chronic health component of the APACHE II score, comorbid conditions); and (2) acute illness component (e.g., APACHE II score at admission, SOFA score, primary diagnostic category, surgical status, acute organ support). Using multiple statistical methods and randomly splitting the cohort into development and validation samples for risk scoring using logistic regression, we examined mortality prediction of each of these components to characterize the timing of transition to persistent critical illness.Results: We included 17,783 patients with a median (IQR) age 61 years (49-71), 62% were male, and mean APACHE II score was 19.0 (7.9). In-hospital mortality was 16.8%. Among patients alive and in ICU, the acute illness component, which accurately predicted outcome at the time of admission [area under the receiver operating characteristics curve (AUC) 0.861; 95% CI 0.860-0.862], progressively lost predictive ability and was no longer more predictive than antecedent characteristics after 9 days. This transition defined the onset of persistent critical illness and comprised 16.1% (n = 2856) of the cohort. Transition ranged between 5 and 21 days across subgroups. In-hospital mortality was greater for those with persistent critical illness [23.9% vs. 15.5%, odds ratio (OR) 1.54; 95% CI 1.43-1.67, p < 0.001]. Persistently critically ill patients accounted for 54.5% of 97844 ICU bed-days and 36.3% of 420119 hospital bed-days, respectively.Conclusions: Persistent critical illness occurred in one in six patients admitted to Alberta ICUs and portended greater risk of death, prolonged ICU and hospital stay, and disproportionate use of health resources compared to patients without persistent critical illness.

Physicians, patients, and families alike perceive a need to improve how goals of care (GOC) decisions occur in chronic critical illness (CCI), but little is currently known about this decision-making process. How do intensivists from various health systems facilitate decision-making about GOC for patients with CCI? What are barriers to, and facilitators of, this decision-making process? We conducted semistructured interviews with a purposeful sample of intensivists from the United States and Canada using a mental models approach adapted from decision science. We analyzed transcripts inductively using qualitative description. We interviewed 29 intensivists from six institutions. Participants across all sites described GOC decision-making in CCI as a complex, longitudinal, and iterative process that involved substantial preparatory work, numerous stakeholders, and multiple family meetings. Intensivists required considerable time to collect information on prior events and conversations, and to arrive at a prognostic consensus with other involved physicians prior to meeting with families. Many intensivists stressed the importance of scheduling multiple family meetings to build trust and relationships prior to explicitly discussing GOC. Physician-identified barriers to GOC decision-making included 1-week staffing models, limited time and cognitive bandwidth, difficulty eliciting patient values, and interpersonal challenges with care team members or families. Potential facilitators included scheduled family meetings at regular intervals, greater interprofessional involvement in decisions, and consistent messaging from care team members. Intensivists described a complex time- and labor-intensive group process to achieve GOC decision-making in CCI. System-level interventions that improve how information is shared between physicians and decrease logistical and relational barriers to timely and consistent communication are key to improving GOC decision-making in CCI.

Purpose: Increasingly, very old patients are admitted to Intensive Care Units (ICUs). The objective of this study was to describe 12-month outcomes of these patients and determine which characteristics are associated with a return to baseline physical function 1 year later.Methods: In this prospective cohort study in 22 Canadian hospitals, we recruited 610 patients aged 80 years or older who were admitted to ICU for at least 24 h. At baseline, we completed a comprehensive geriatric assessment and followed patients to determine 12-month survival and physical function. Our primary outcome was physical recovery from critical illness at 12 months, defined as being alive with Short Form-36 physical function score of at least 10 points, and not 10 or more points below baseline. We used regression analysis to examine factors associated with physical recovery.Results: Patients were on average 84 years old (range 80-99). Mortality was 14% in ICU, 26% in hospital and 44% at 12 months after admission. Of 505 patients evaluable at 12 months, 26% achieved physical recovery. In the multivariable model, physical recovery was significantly associated with younger age, lower APACHE II score, lower Charlson comorbidity score, lower frailty index, lower baseline physical function score, and specific admission diagnoses.Conclusions: One-quarter of patients aged 80 years or older who are admitted to ICU survived and returned to baseline levels of physical function at 1 year. Routine assessment of baseline physical function and frailty status could aid in prognostication and informed decision-making for very old critically ill patients.

Background: Transfer of patient care from an intensive care unit (ICU) to a hospital ward is often challenging, high risk and inefficient. We assessed patient and provider perspectives on barriers and facilitators to high-quality transfers and recommendations to improve the transfer process.Methods: We conducted semistructured interviews of participants from a multicentre prospective cohort study of ICU transfers conducted at 10 hospitals across Canada. We purposively sampled 1 patient, 1 family member of a patient, 1 ICU provider, and 1 ward provider at each of the 8 English-speaking sites. Qualitative content analysis was used to derive themes, subthemes and recommendations.Results: The 35 participants described 3 interrelated, overarching themes perceived as barriers or facilitators to high-quality patient transfers: resource availability, communication and institutional culture. Common recommendations suggested to improve ICU transfers included implementing standardized communication tools that streamline provider-provider and provider-patient communication, using multimodal communication to facilitate timely, accurate, durable and mutually reinforcing information transfer; and developing procedures to manage delays in transfer to ensure continuity of care for patients in the ICU waiting for a hospital ward bed.Interpretation: Patient and provider perspectives attribute breakdown of ICU-to-ward transfers of care to resource availability, communication and institutional culture. Patients and providers recommend standardized, multimodal communication and transfer procedures to improve quality of care. [ABSTRACT FROM AUTHOR]

Purpose: To provide a 360-degree description of ICU-to-ward transfers.Methods: Prospective cohort study of 451 adults transferred from a medical-surgical ICU to a hospital ward in 10 Canadian hospitals July 2014-January 2016. Transfer processes documented in the medical record. Patient (or delegate) and provider (ICU/ward physician/nurse) perspectives solicited by survey 24-72 h after transfer.Results: Medical records (100%) and survey responses (ICU physicians-80%, ICU nurses-80%, ward physicians-46%, ward nurses-64%, patients-74%) were available for most transfers. The median time from initiation to completion of transfer was 25 h (IQR 6-52). ICU physicians and nurses reported communicating with counterparts via telephone (78 and 75%) when transfer was requested (82 and 24%) or accepted (31 and 59%) and providing more elements of clinical information than ward physicians (mean 4.7 vs. 3.9, p < 0.001) and nurses (5.0 vs. 4.4, p < 0.001) reported receiving. Patients were more likely to report satisfaction with the transfer when they received more information (OR 1.32, 95% CI 1.18-1.48), had their questions addressed (OR 3.96, 95% CI 1.33-11.84), met the ward physician prior to transfer (OR 4.61, 95% CI 2.90-7.33), and were assessed by a nurse within 1 h of ward arrival (OR 4.70, 95% CI 2.29-9.66). Recommendations for improvement included having a documented care plan travel with the patient (all stakeholders), standardized face-to-face handover (physicians), avoiding transfers at shift change (nurses) and informing patients about pending transfers in advance (patients).Conclusions: ICU-to-ward transfers are characterized by failures of patient flow and communication; experienced differently by patients, ICU/ward physicians and nurses, with distinct suggestions for improvement.

Objective: Effective communication between clinicians is essential for seamless discharge of patients between care settings. Yet, discharge summaries are commonly not available and incomplete. We implemented and evaluated a structured electronic health record-embedded electronic discharge (eDischarge) summary tool for patients discharged from the ICU to a hospital ward.Design: Multiple baseline trial with randomized and staggered implementation.Setting: Adult medical-surgical ICUs at four acute care hospitals serving a single Canadian city.Patients: Health records of patients 18 years old or older, in the ICU 24 hours or longer, and discharged from the ICU to an in-hospital patient ward between February 12, 2018, and June 30, 2019.Intervention: A structured electronic note (ICU eDischarge tool) with predefined fields (e.g., diagnosis) embedded in the hospital-wide electronic health information system.Measurements and Main Results: We compared the percent of timely (available at discharge) and complete (included goals of care designation, diagnosis, list of active issues, active medications) discharge summaries pre and post implementation using mixed effects logistic regression models. After implementing the ICU eDischarge tool, there was an immediate and sustained increase in the proportion of patients discharged from ICU with timely and complete discharge summaries from 10.8% (preimplementation period) to 71.1% (postimplementation period) (adjusted odds ratio, 32.43; 95% CI, 18.22-57.73). No significant changes were observed in rapid response activation, cardiopulmonary arrest, death in hospital, ICU readmission, and hospital length of stay following ICU discharge. Preventable (60.1 vs 5.7 per 1,000 d; p = 0.023), but not nonpreventable (27.3 vs 40.2 per 1,000d; p = 0.54), adverse events decreased post implementation. Clinicians perceived the eDischarge tool to produce a higher quality discharge process.Conclusions: Implementation of an electronic tool was associated with more timely and complete discharge summaries for patients discharged from the ICU to a hospital ward.

Background: Critical care research in Canada is conducted primarily in academically-affiliated intensive care units with established research infrastructure, including research coordinators (RCs). Recently, efforts have been made to engage community hospital ICUs in research albeit with barriers. Automation or artificial intelligence (AI) could aid the performance of routine research tasks. It is unclear which research study processes might be improved through AI automation. Methods:We conducted a cross-sectional survey of Canadian ICU research personnel. The survey contained items characterizing opinions regarding research processes that may be amenable to AI automation. We distributed the questionnaire via email distribution lists of 3 Canadian research societies. Open-ended questions were analyzed using a thematic content analysis approach. Results: A total of 49 survey responses were received (response rate: 8%). Tasks that respondents felt were time-consuming/tedious/tiresome included: screening for potentially eligible patients (74%), inputting data into case report forms (65%), and preparing internal tracking logs (53%). Tasks that respondents felt could be performed by AI automation included: screening for eligible patients (59%), inputting data into case report forms (55%), preparing internal tracking logs (51%), and randomizing patients into studies (45%). Open-ended questions identified enthusiasm for AI automation to improve information accuracy and efficiency while freeing up RCs to perform tasks that require human interaction. This enthusiasm was tempered by the need for proper AI education and oversight. Conclusions: There were balanced supportive (increased efficiency and re-allocation of tasks) and challenges (informational accuracy and oversight) with regards to AI automation in ICU research.

Open in new tab Download slide OBJECTIVES The comparative effectiveness and safety of proton pump inhibitors (PPIs) versus histamine-2 receptor blockers for stress ulcer prophylaxis in the cardiac surgical intensive care unit population is uncertain. Although the Proton Pump Inhibitors versus Histamine-2 Receptor Blockers for Ulcer Prophylaxis Therapy in the Intensive Care Unit (PEPTIC) trial reported a higher risk of mortality in the PPI arm with no difference in gastrointestinal bleeding, detailed information on surgical variables and clinically relevant surgical subgroups was not available. METHODS The analysis included all Canadian cardiac surgery patients enrolled in the PEPTIC trial. Data were electronically linked using unique patient identifiers to a clinical information system. Outcomes of interest included in-hospital mortality, gastrointestinal bleeding, Clostridium difficile infections, ventilator-associated conditions and length of stay. RESULTS We studied 823 (50.6%) randomized to PPIs and 805 (49.4%) to histamine-2-receptor blockers. In the intention-to-treat analysis, there were no differences in hospital mortality [PPI: 4.3% vs histamine-2 receptor blockers: 4.8%, adjusted odds ratio (aOR) 0.97, 95% confidence interval (CI) 0.55–1.70], gastrointestinal bleeding (3.9% vs 4.8%, aOR 1.09, 95% CI 0.66–1.81), C. difficile infections (0.9% vs 0.1%, aOR 0.18, 95% CI 0.02–1.59), ventilator-associated conditions (1.6% vs 1.7%, aOR 0.92, 95% CI 0.85–1.00) or median length of stay (9.2 vs 9.8 days, adjusted risk ratio 1.06, 85% CI 0.99–1.13). No significant treatment differences were observed among subgroups of interest or per-protocol populations. CONCLUSIONS In a secondary analysis of cardiac surgery patients enrolled in the PEPTIC trial in Canada, no differences in effectiveness or safety were observed between use of PPIs and histamine-2 receptor blockers for stress ulcer prophylaxis.

Objective: Many healthcare workers are concerned about the provision of nonbeneficial treatment in the acute care setting. We sought to explore the perceptions of acute care practitioners to determine whether they perceived nonbeneficial treatment to be a problem, to generate an acceptable definition of nonbeneficial treatment, to learn about their perceptions of the impact and causes of nonbeneficial treatment, and the ways that they feel could reduce or resolve nonbeneficial treatment. Design: National, bilingual, cross-sectional survey of a convenience sample of nursing and medical staff who provide direct patient care in acute medical wards or ICUs in Canada. Main Results: We received 688 responses (response rate 61%) from 11 sites. Seventy-four percent of respondents were nurses. Eighty-two percent of respondents believe that our current means of resolving nonbeneficial treatment are inadequate. The most acceptable definitions of nonbeneficial treatment were "advanced curative/life-prolonging treatments that would almost certainly result in a quality of life that the patient has previously stated that he/she would not want" (88% agreement) and "advanced curative/ life-prolonging treatments that are not consistent with the goals of care (as indicated by the patient)" (83% agreement). Respondents most commonly believed that nonbeneficial treatment was caused by substitute decision makers who do not understand the limitations of treatment, or who cannot accept a poor prognosis (90% agreement for each cause), and 52% believed that nonbeneficial treatment was "often" or "always" continued until the patient died or was discharged from hospital. Respondents believed that nonbeneficial treatment was a common problem with a negative impact on all stakeholders (> 80%) and perceived that improved advance care planning and communication training would be the most effective (92% and 88%, respectively) and morally acceptable (95% and 92%, respectively) means to resolve the problem of nonbeneficial treatment. Conclusions: Canadian nurses and physicians perceive that our current means of resolving nonbeneficial treatment are inadequate, and that we need to adopt new techniques of resolving nonbeneficial treatment. The most promising strategies to reduce nonbeneficial treatment are felt to be improved advance care planning and communication training for healthcare professionals. [ABSTRACT FROM AUTHOR]

Background: Graduating medical students from the class of 1999 from McGill University and the University of Alberta completed a self-administered, anonymous, pilot survey to determine students' perspectives on how their educational experience in common palliative care topics contrasted with their educational experience in the diagnosis and management of hypertension, non palliative aspects of breast cancer, and patients dying of acquired immune deficiency syndrome (AIDS). Methods: A Likert scale ranging from "excellent," scored 1, "very poor," scored 5, was used. Students also estimated the number of hours they spent, during their training, in operating rooms, on home visits to terminally ill patients, and in interprofessional teaching. Results: Sixty of 114 (53%) students from McGill University, and 53 of 110 (48%) students from the University of Alberta responded to the survey. The mean ratings of education experience in the various topics for both universities combined were as follows: hypertension, 2.03; breast cancer, 2.33; cancer pain, 3.42; communicating with dying patients, 3.32; and caring for patients with AIDS, 4.15. The average number of hours spent in the operating room, on home visits to terminally patients, and in interprofessional teaching for both universities combined were 155 hours, 4.2 hours, and 16 hours, respectively. Of the responding students from both universities 83% favored increased palliative care teaching. Conclusion: Despite the disproportionate number of hours spent in operating rooms compared to palliative care community exposure, only two students, one from each university, favored shortening surgical rotations to allow for increased time for palliative care education. Recommendations, including increasing palliative care education during clinical clerkships, are provided to improve medical students' perceptions of their educational experiences in palliative care education.

Objectives: The optimum duration of antimicrobial treatment for patients with bacteremia is unknown. Our objectives were to determine duration of antimicrobial treatment provided to patients who have bacteremia in ICUs, to assess pathogen/patient factors related to treatment duration, and to assess the relationship between treatment duration and survival.Design: Retrospective cohort study.Settings: Fourteen ICUs across Canada.Patients: Patients with bacteremia and were present in the ICU at the time culture reported positive.Interventions: Duration of antimicrobial treatment for patients who had bacteremia in ICU.Measurements and Main Results: Among 1,202 ICU patients with bacteremia, the median duration of treatment was 14 days, but with wide variability (interquartile range, 9-17.5). Most patient characteristics were not associated with treatment duration. Coagulase-negative staphylococci were the only pathogens associated with shorter treatment (odds ratio, 2.82; 95% CI, 1.51-5.26). The urinary tract was the only source of infection associated with a trend toward lower likelihood of shorter treatment (odds ratio, 0.67; 95% CI, 0.42-1.08); an unknown source of infection was associated with a greater likelihood of shorter treatment (odds ratio, 2.14; 95% CI, 1.17-3.91). The association of treatment duration and survival was unstable when analyzed based on timing of death.Conclusions: Critically ill patients who have bacteremia typically receive long courses of antimicrobials. Most patient/pathogen characteristics are not associated with treatment duration; survivor bias precludes a valid assessment of the association between treatment duration and survival. A definitive randomized controlled trial is needed to compare shorter versus longer antimicrobial treatment in patients who have bacteremia. [ABSTRACT FROM AUTHOR]

Background: We aimed to determine the impact of nighttime discharge from the intensive care unit (ICU) to the ward on hospital mortality and readmission rates in consecutive critically ill patients admitted to five Canadian ICUs. We hypothesized that hospital mortality and readmission rates would be higher for patients discharged after hours compared with discharge during the day.Methods: A multi-center retrospective cohort study was carried out at five hospitals in Edmonton, Canada, between July 2002 and December 2009. Nighttime discharge was defined as discharge from the ICU occurring between 07:00 pm and 07:59 am. Logistic regression analysis was used to explore the associations between nighttime discharge and outcomes.Results: Of 19,622 patients discharged alive from the ICU, 3,505 (17.9%) discharges occurred during nighttime. Nighttime discharge occurred more commonly among medical than surgical patients (19.9% vs. 13.8%, P < 0.001) and among those with more comorbid conditions, compared with daytime discharged patients. Crude hospital mortality (11.8% versus 8.8%, P < 0.001) was greater for nighttime discharged as compared to daytime discharged patients. In a multivariable analysis, after adjustment for comorbidities, diagnosis and source of admission, nighttime discharge remains associated with higher mortality (odds ratio [OR] 1.29; 95% CI, 1.14 to 1.46, P < 0.001). This finding was robust in two sensitivity analyses examining discharges occurring between 00:00 am and 04:59 am (OR 1.28; 1.12-1.47; P < 0.001) and for those who died within 48 h of ICU discharge without readmission (OR 1.24; 1.07-1.42, P = 0.002). There was no difference in ICU readmission for nighttime compared with daytime discharges (7.4% vs. 6.9 %, p = 0.26). However, rates were higher for nighttime discharges in community compared with tertiary hospitals (7.7% vs. 5.7%, P = 0.023).Conclusions: In a large integrated health region, 1 in 5 ICU patients are discharged at nighttime, a factor with increasing occurrence during our study and shown to be independently associated with higher hospital mortality.

The article discusses a study conducted to describe perspectives of family members about care provided to patients who were aged 80 years or over in Intensive Care Units (ICUs) across Canada. Topics discussed include study procedure, statistical analysis of the study and results of the study, which reveal incongruity between family values and preferences for end-of-life care and actual care received for very elderly patients.

Background Little is known about factors that influence the timing of initiation of renal replacement therapy (RRT) for acute kidney injury (AKI). We sought to better describe these factors for Canadian physicians that prescribe RRT for AKI. Methods A web-based survey was conducted of physicians involved in the decision to initiate RRT for critically ill patients in Canada. Participants were asked about the factors that prompt them to initiate RRT for AKI both directly and using scenario-based questions. Results Surveys completed by 180 physicians at 32 different sites were included for analysis. Serum potassium level and severity of pulmonary edema were the most commonly utilized factors for deciding when RRT should be started. For all clinical and laboratory factors inquired about, there was wide variation in the minimum severity that prompted respondents to indicate that they would initiate RRT. Additional factors that influenced the timing of initiation were the time-of-day that laboratory and clinical results became available, patient age and co-morbidity, responsiveness to a diuretic challenge and the specialty of the prescribing physician. Over 90% of respondents indicated that a randomized controlled trial to assess the optimal timing of initiation of RRT for AKI is ethically justified. Conclusions These results provide insight into clinical and laboratory factors that influence the timing of initiation of RRT for AKI and may aid in the design of future trials. While most clinicians consider the degree of hyperkalemia and pulmonary edema in deciding when to initiate RRT for AKI, there is a wide range of clinical practice, uncertainty regarding the optimal timing of initiation and enthusiasm for prospective interventional studies to address this topic.

The article discusses a study which described the characteristics, treatment and outcomes of critically ill patients in Canada with 2009 influenza A(H1N1) infection. The study used 168 critically ill patients with 2009 influenza A(H1N1) infection in various Canadian adult and pediatric intensive care units (ICUs) during the period April 16-August 12, 2009. Primary outcome measures for the study were 28-day and 90-day mortality, while secondary measures included frequency and duration of mechanical ventilation and duration of stay in the ICU. Occurrence of critical illness in 215 patients with community-acquired 2009 influenza A(H1N1) infection was observed in the study. It also concluded that critical illness due to the virus has occurred rapidly after hospital admission.
