Worker Experiences of the Work Health and Safety Impacts of Exposure to Dying and Death in Clinical Settings: A Qualitative Scoping Review

Workers employed in clinical healthcare settings often encounter dying and death of patients as a part of their role. This scoping review aimed to explore the physical and psychosocial OHS impacts on health workers exposed to death within their occupational role and their inherent coping strategies. Six electronic databases PsycINFO (Ovid), Medline (Ovid), AMED (EBSCO), CINAHL (EBSCO), and Proquest Social Sciences were searched for peer reviewed research articles published between March 1971 and April 2022. PRISMA-ScR guidelines were followed. Three authors independently assessed articles for inclusion. Fifty-three studies with focus settings in hospitals, hospice, general practice and residential care were identified. Five main themes were developed and organized using and ergonomic systems approach: Cultural Environment, Workplace, Job Demands, Impacts and Coping. The findings demonstrate that caring for dying patients, the dead and their families in clinical settings impacts workers emotionally, physically, behaviorally and spiritually.

The time-course of cortico-limbic neural responses to air hunger

Several studies have mapped brain regions associated with acute dyspnea perception. However, the time-course of brain activity during sustained dyspnea is unknown. Our objective was to determine the time-course of neural activity when dyspnea is sustained. Eight healthy subjects underwent brain blood oxygen level dependent functional magnetic imaging (BOLD-fMRI) during mechanical ventilation with constant mild hypercapnia (∼ 45 mm Hg). Subjects rated dyspnea (air hunger) via visual analog scale (VAS). Tidal volume (V(T)) was alternated every 90 s between high VT (0.96 ± 0.23 L) that provided respiratory comfort (12 ± 6% full scale) and low V(T) (0.48 ± 0.08 L) which evoked air hunger (56 ± 11% full scale). BOLD signal was extracted from a priori brain regions and combined with VAS data to determine air hunger related neural time-course. Air hunger onset was associated with BOLD signal increases that followed two distinct temporal profiles within sub-regions of the anterior insula, anterior cingulate and prefrontal cortices (cortico-limbic circuitry): (1) fast, BOLD signal peak <30s and (2) slow, BOLD signal peak >40s. BOLD signal during air hunger offset followed fast and slow temporal profiles symmetrical, but inverse (signal decreases) to the time-courses of air hunger onset. We conclude that differential cortico-limbic circuit elements have unique contributions to dyspnea sensation over time. We suggest that previously unidentified sub-regions are responsible for either the acute awareness or maintenance of dyspnea. These data enhance interpretation of previous studies and inform hypotheses for future dyspnea research.

Hospice care and the emergency department: rules, regulations, and referrals

Emergency clinicians often care for patients with terminal illness who are receiving hospice care and many more patients who may be in need of such care. Hospice care has been shown to successfully address the multidimensional aspects of the end-of-life concerns of terminally ill patients: dying with dignity, dying without pain, reducing the burden on family and caregivers, and achieving a home death, when desired. Traditional emergency medicine training may fail to address hospice as a system of care. When they are unfamiliar with the hospice model, emergency clinicians, patients, and caregivers may find it difficult to properly use and interact with these care services. Potential poor outcomes include the propagation of misleading or inaccurate information about the hospice system and the failure to guide appropriate patient referrals. This article reviews the hospice care service model and benefits offered, who may qualify for hospice care, common emergency presentations in patients under hospice care, and a stepwise approach to initiating a hospice care referral in the emergency department.

Ethical issues and clinical expertise at the end of life

Oncology care has changed markedly in the past decade. With new therapies, patients are experienced in living with life-threatening illness and believe in the abilities of science and the health care system to find new therapies. Changes in the treatment paradigm have altered oncology nursing practice. The integration of newer targeted therapies with their specific side-effect profiles also has changed end-of-life care. Strategies used to manage patients during the active treatment phase of illness can inform and improve nursing practice when active care has been set aside. Evidence-based practice provides a guide to identify, critically appraise, and use evidence to solve clinical problems.

Symptom management in the older adult

Palliative care begins at the time of diagnosis of a life-threatening illness and continues beyond the time of death. Defined in the broadest sense, the goal of palliative care is to provide aggressive symptom management and address the psychological and spiritual needs of the patient and the family. This article reviews the management of some symptoms commonly observed in older patients, highlighting treatment considerations specific to the older population. Ultimately the approach to symptoms must be individualized, and treatment decisions must reflect the patient's goals of care. Although symptom management in older patients may be challenging, it is possible to provide care that significantly enhances quality of life throughout the course of illness.
