Nursing Presence During End-of-Life Care in the ICU with a Focus on Discontinuing Mechanical Ventilation
Bibliographic record
Abstract
Background: In certain jurisdictions around the world, the withdrawal of life-sustaining measures is part of end-of-life care in the intensive care unit. Nurses, as primary providers of care, are often active participants in the coordination and actualization of the withdrawal process. The withdrawal of mechanical ventilation is arguably one of the more complex aspects of the withdrawal process. Aims: To review current published professional literature on the topics of intensive care nurses’ experiences of withdrawing of life-sustaining measures (Vanderspank et al., 2018) and withdrawing mechanical ventilation for compassionate means (Efstathiou et al., 2020), as well as explore the ways in which certain jurisdictions, namely Canada, have sought to standardize withdrawal of life-sustaining measures processes (Healy et al., 2020). Methods: First, a detailed overview of the findings of a qualitative evidence synthesis on nurses’ experiences of withdrawing life-sustaining measures is presented (Vanderspank et a., 2018). Second, a systematic review and narrative synthesis of “perceptions, experiences and practices” of compassionate withdrawal of mechanical ventilation is described (Efstathiou et al., p. 1140X). The latter review was registered with PROSPERO (CRD42018086495) and modelled on a Cochrane approach. The search, with a phenomenon of interest being all forms of terminal withdrawal of mechanical ventilation, was executed in the following databases Medline and Medline in Process (via Ovid), Embase Class + Embase (via Ovid), Cochrane's Central Registry for Randomized Controlled Trials CENTRAL (via Ovid) and Cumulative Index of Nursing and Allied Health Literature (CINAHL, via EBSCOHost). Third, a Canadian initiative that included the development of a framework and a toolkit for the withdrawal of life-sustaining measures, was discussed. Findings: Specific to the Efstathiou et al. (2020) systematic review, 25 manuscripts were ultimately included in the review comprised of qualitative and qualitative designs as well as one Delphi study and encompassed findings from nine countries. The synthesized findings were reported under four themes. Conclusions: Death and dying is a reality of critical care practice. In jurisdictions where the withdrawal of life-sustaining measures is practiced, particular attention can be paid to the complexity of mechanical ventilation discontinuation for compassionate means. Critical care nurses demonstrate practice expertise related to the withdrawal of life-sustaining measures and their expert nursing knowledge and care has impact on the patient and family experience of death and dying in the intensive care unit. Regardless of jurisdictional practices, high-quality, end-of-life care is possible in the critical care context.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
