Improving quality of withdrawal of life-sustaining measures in organ donation: a framework and implementation toolkit.

ABSTRACT: BACKGROUND:Donation after circulatory determination of death (DCD) is responsible for the largest increase in deceased donation over the past decade. When the Canadian DCD guideline was published in 2006, it included recommendations to create standard policies and procedures for withdrawal of life-sustaining measures (WLSM) as well as quality assurance frameworks for this practice. In 2016, the Canadian Critical Care Society produced a guideline for WLSM that requires modifications to facilitate implementation when DCD is part of the end-of-life care plan. METHODS:A pan-Canadian multidisciplinary collaborative was convened to examine the existing guideline framework and to create tools to put the existing guideline into practice in centres that practice DCD. RESULTS:A set of guiding principles for implementation of the guideline in DCD practice were produced using an iterative, consensus-based approach followed by development of four implementation tools and three quality assurance and audit tools. CONCLUSIONS:The tools developed will aid DCD centres in fulsomely adapting the Canadian Critical Care Society Withdrawal of Life-Sustaining Measures guideline.

Project description:BackgroundIn patients with severe brain injury, withdrawal of life-sustaining measures (WLSM) is common in intensive care units (ICU). WLSM constitutes a dilemma: instituting WLSM too early could result in death despite the possibility of an acceptable functional outcome, whereas delaying WLSM could unnecessarily burden patients, families, clinicians, and hospital resources. We aimed to describe the occurrence and timing of WLSM, and factors associated with timing of WLSM in European ICUs in patients with traumatic brain injury (TBI).MethodsThe CENTER-TBI Study is a prospective multi-center cohort study. For the current study, patients with traumatic brain injury (TBI) admitted to the ICU and aged 16 or older were included. Occurrence and timing of WLSM were documented. For the analyses, we dichotomized timing of WLSM in early (< 72 h after injury) versus later (≥ 72 h after injury) based on recent guideline recommendations. We assessed factors associated with initiating WLSM early versus later, including geographic region, center, patient, injury, and treatment characteristics with univariable and multivariable (mixed effects) logistic regression.ResultsA total of 2022 patients aged 16 or older were admitted to the ICU. ICU mortality was 13% (n = 267). Of these, 229 (86%) patients died after WLSM, and were included in the analyses. The occurrence of WLSM varied between regions ranging from 0% in Eastern Europe to 96% in Northern Europe. In 51% of the patients, WLSM was early. Patients in the early WLSM group had a lower maximum therapy intensity level (TIL) score than patients in the later WLSM group (median of 5 versus 10) The strongest independent variables associated with early WLSM were one unreactive pupil (odds ratio (OR) 4.0, 95% confidence interval (CI) 1.3-12.4) or two unreactive pupils (OR 5.8, CI 2.6-13.1) compared to two reactive pupils, and an Injury Severity Score (ISS) if over 41 (OR per point above 41 = 1.1, CI 1.0-1.1). Timing of WLSM was not significantly associated with region or center.ConclusionWLSM occurs early in half of the patients, mostly in patients with severe TBI affecting brainstem reflexes who were severely injured. We found no regional or center influences in timing of WLSM. Whether WLSM is always appropriate or may contribute to a self-fulfilling prophecy requires further research and argues for reluctance to institute WLSM early in case of any doubt on prognosis.

Project description:To measure the frequency of withdrawal of life-sustaining therapy for perceived poor neurologic prognosis among decedents in hospitals of different sizes and teaching statuses.DesignWe performed a multicenter, retrospective cohort study.SettingFour large teaching hospitals, four affiliated small teaching hospitals, and nine affiliated nonteaching hospitals in the United States.PatientsWe included a sample of all adult inpatient decedents between August 2017 and August 2019.Measurements and main resultsWe reviewed inpatient notes and categorized the immediately preceding circumstances as withdrawal of life-sustaining therapy for perceived poor neurologic prognosis, withdrawal of life-sustaining therapy for nonneurologic reasons, limitations or withholding of life support or resuscitation, cardiac death despite full treatment, or brain death. Of 2,100 patients, median age was 71 years (interquartile range, 60-81 yr), median hospital length of stay was 5 days (interquartile range, 2-11 d), and 1,326 (63%) were treated at four large teaching hospitals. Withdrawal of life-sustaining therapy for perceived poor neurologic prognosis occurred in 516 patients (25%) and was the sole contributing factor to death in 331 (15%). Withdrawal of life-sustaining therapy for perceived poor neurologic prognosis was common in all hospitals: 30% of deaths at large teaching hospitals, 19% of deaths in small teaching hospitals, and 15% of deaths at nonteaching hospitals. Withdrawal of life-sustaining therapy for perceived poor neurologic prognosis happened frequently across all hospital units. Withdrawal of life-sustaining therapy for perceived poor neurologic prognosis contributed to one in 12 deaths in patients without a primary neurologic diagnosis. After accounting for patient and hospital characteristics, significant between-hospital variability in the odds of withdrawal of life-sustaining therapy for perceived poor neurologic prognosis persisted.ConclusionsA quarter of inpatient deaths in this cohort occurred after withdrawal of life-sustaining therapy for perceived poor neurologic prognosis. The rate of withdrawal of life-sustaining therapy for perceived poor neurologic prognosis occurred commonly in all type of hospital settings. We observed significant unexplained variation in the odds of withdrawal of life-sustaining therapy for perceived poor neurologic prognosis across participating hospitals.

Project description:Background and purposeImpaired level of consciousness (LOC) on presentation at hospital admission in patients with intracerebral hemorrhage (ICH) may affect outcomes and the decision to withhold or withdraw life-sustaining treatment (WOLST).MethodsPatients with ICH were included across 121 Florida hospitals participating in the Florida Stroke Registry from 2010 to 2019. We studied the effect of LOC on presentation on in-hospital mortality (primary outcome), WOLST, ambulation status on discharge, hospital length of stay, and discharge disposition.ResultsAmong 37 613 cases with ICH (mean age 71, 46% women, 61% White, 20% Black, 15% Hispanic), 12 272 (33%) had impaired LOC at onset. Compared with cases with preserved LOC, patients with impaired LOC were older (72 versus 70 years), more women (49% versus 45%), more likely to have aphasia (38% versus 16%), had greater ICH score (3 versus 1), greater risk of WOLST (41% versus 18%), and had an increased in-hospital mortality (32% versus 12%). In the multivariable-logistic regression with generalized estimating equations accounting for basic demographics, comorbidities, ICH severity, hospital size and teaching status, impaired LOC was associated with greater mortality (odds ratio, 3.7 [95% CI, 3.1-4.3], P<0.0001) and less likely discharged home or to rehab (odds ratio, 0.3 [95% CI, 0.3-0.4], P<0.0001). WOLST significantly mediated the effect of impaired LOC on mortality (mediation effect, 190 [95% CI, 152-229], P<0.0001). Early WOLST (<2 days) occurred among 51% of patients. A reduction in early WOLST was observed in patients with impaired LOC after the 2015 American Heart Association/American Stroke Association ICH guidelines recommending aggressive treatment and against early do-not-resuscitate.ConclusionsIn this large multicenter stroke registry, a third of ICH cases presented with impaired LOC. Impaired LOC was associated with greater in-hospital mortality and worse disposition at discharge, largely influenced by early decision to withhold or WOLST.

Project description:Background:The demand for solid organ transplantation has spurred countries around the world to search for innovative policies and practices to increase the supply of organs. Spain has become a global reference point for organ donation with the highest transplantation rates. In Ontario, Canada the Ontario Trillium Gift of Life (TGLN) has sought to replicate some of the successes in Spain. In particular, TGLN's implementation of the Physician Leadership Model has been viewed as a promising strategy to improve donation conversion rates. Objective:The objective of this study was to evaluate the implementation of TGLNs (TGLN) Physician Leadership Model by examining critical implementation process variables (education/training, communication, satisfaction, participation and reach). Methods:This mixed-method implementation evaluation included data from all members of the Physician Leadership Model including the Chief Medical Officer, five Regional Medical Leads (RMLs), and the 52 Hospital Donation Physicians (HDPs). Social Network Analysis (SNA) surveys were sent to all 52 HDPs and yielded an 85% rate. Analysis included constructing sociograms and qualitatively analyzing interviews. Results:TGLN's PLM was poised for success by utilizing the existing RMLs' network as a foundation. The social network analysis measures, particularly participation and reach, indicated the PLM was quite dense (ie, the degree to which members are connected) at baseline. HDPs reported communication to be facilitated by their connections to their RMLs. Early evaluative data indicated that lack of education and training was viewed by HDPs as a barrier, and thus more capacity would need to be directed to this issue. Overall, HDPs reported that various intended outcomes were being met. Conclusion:We have demonstrated that an implementation evaluation helps us to understand which elements of the PLM were successful and which elements required immediate attention. This evaluation helped to highlight the successes and challenges in implementing the TGLN Physician Leadership Model in Ontario. Social network analysis of publicly funded capacity building systems has been identified as a promising area for health program evaluation to answer questions at a system level, such as identifying service provisions among information exchange networks and ultimately better health care.
