How contextual and relational aspects shape the perspective of healthcare providers on decision making for patients with disorders of consciousness: a qualitative interview study

"Fluctuation is the norm": Rehabilitation practitioner perspectives on ambiguity and uncertainty in their work with persons in disordered states of consciousness after traumatic brain injury

The purpose of this study is to describe the clinical lifeworld of rehabilitation practitioners who work with patients in disordered states of consciousness (DoC) after severe traumatic brain injury (TBI). We interviewed 21 practitioners using narrative interviewing methods from two specialty health systems that admit patients in DoC to inpatient rehabilitation. The overarching theme arising from the interview data is "Experiencing ambiguity and uncertainty in clinical reasoning about consciousness" when treating persons in DoC. We describe practitioners' practices of looking for consistency, making sense of ambiguous and hard to explain patient responses, and using trial and error or "tinkering" to care for patients. Due to scientific uncertainty about diagnosis and prognosis in DoC and ambiguity about interpretation of patient responses, working in the field of DoC disrupts the canonical meaning-making processes that practitioners have been trained in. Studying the lifeworld of rehabilitation practitioners through their story-making and story-telling uncovers taken-for-granted assumptions and normative structures that may exist in rehabilitation medical and scientific culture, including practitioner training. We are interested in understanding these canonical breaches in order to make visible how practitioners make meaning while treating patients.

Partially dead, partially separated: establishing the mechanism between ambiguous loss and grief reaction among caregivers of patients with prolonged disorders of consciousness

OBJECTIVES:

To trace the psychological mechanism underlying caregivers' emotional experience in prolonged disorders of consciousness, by examining the mediating role of boundary ambiguity in the relationship between ambiguous loss and grief.

DESIGN:

Cross-sectional design.

SETTING:

The Respiratory Rehabilitation Division of a long-term medical and rehabilitation institute.

SUBJECTS:

A total of 64 primary caregivers (69% female) of patients in a vegetative state ( n = 49) or minimally conscious state ( n = 15), with a mean age of 55.5 (SD = 12.3) years. Participants were mostly the patient's children (62%) or partners (27%). The mean caregiving duration was 4.9 (SD = 5.1) years.

MAIN MEASURES:

The Boundary Ambiguity Scale, the Revised Need for Closure Scale, an adapted version of the multifactor Two-Track Bereavement Questionnaire, and a sociodemographic questionnaire, which included items regarding caregiving: frequency of visits and perception of the patient's psychological presence.

RESULTS:

(1) Caregivers' grief scores (total TTBQ: mean = 2.97; SD = 0.55) did not significantly differ from those exhibited by a normative bereavement sample. (2) Time since injury did not affect caregivers' grief scores (three-year cut-point; P > .05). (3) Mediation analyses revealed that boundary ambiguity (mean = 34.03; SD = 7.55) significantly mediates the relationship between need for closure ( B = .11; confidence interval (CI) = .04-.23) and grief; frequency of visits ( B = .05, CI = .02-.10) and grief and perception of psychological presence ( B = .26, CI = .00-.61) and grief in three separate models.

CONCLUSION:

Ambiguity concerning relational boundaries hinders caregivers' ongoing grief reaction and impedes their ability to integrate the loss. High frequency of visits, belief in the patient's psychological presence and difficulties in tolerating uncertainty are all clinical manifestations of caregivers' entangled experience.

Online public reactions to fMRI communication with patients with disorders of consciousness: Quality of life, end-of-life decision making, and concerns with misdiagnosis

BACKGROUND

Recently, the news media have reported on the discovery of covert awareness and the establishment of limited communication using a functional magnetic resonance imaging (fMRI) neuroimaging technique with several brain-injured patients thought to have been in a vegetative state. This discovery has raised many ethical, legal, and social questions related to quality of life, end-of-life decision making, diagnostic and prognostic accuracy in disorders of consciousness, resource allocation, and other issues. This project inquires into the public responses to these discoveries.

METHODS

We conducted a thematic analysis of online comments (n = 779) posted in response to 15 news articles and blog posts regarding the case of a Canadian patient diagnosed for 12 years as in a vegetative state, but who was reported in 2012 as having been able to communicate via fMRI. The online comments were coded using an iteratively refined codebook structured around 14 main themes.

RESULTS

Among the most frequent public reactions revealed in the online comments were discussions of the quality of life of patients with disorders of consciousness, whether life-sustaining treatment should be withdrawn (and whether the fMRI communication technique should be used to ask patients about this), and misgivings about the accuracy of diagnosis in disorders of consciousness and brain death.

CONCLUSIONS

These public perspectives are relevant to the obligations of clinicians, lawyers, and public policymakers to patients, families, and the public. Future work should consider how best to alleviate families' concerns as this type of research shakes their faith in diagnostic accuracy, to clarify the legal rules relating to advance directives in this context, and to address the manner in which public messaging might help to alleviate any indirect impact on confidence in the organ donation system.

Physicians' attitudes toward medical and ethical challenges for patients in the vegetative state: comparing Canadian and German perspectives in a vignette survey

BACKGROUND

Physicians treating patients in the vegetative state (VS) must deal with uncertainty in diagnosis and prognosis, as well as ethical issues. We examined whether physicians' attitudes toward medical and ethical challenges vary across two national medical practice settings.

METHODS

A comparative survey was conducted among German and Canadian specialty physicians, based on a case vignette about the VS. Similarities and differences of participants' attitudes toward medical and ethical challenges between the two samples were analyzed with non-parametric tests (Mann-Whitney-U-Test).

RESULTS

The overall response rate was 13.4%. Eighty percent of all participants correctly applied the diagnostic category of VS with no significant differences between countries. Many of the participants who chose the correct diagnosis of VS attributed capabilities to the patient, particularly the ability to feel pain (70%), touch (51%) and to experience hunger and thirst (35%). A large majority of participants (94%) considered the limitation of life-sustaining treatment (LST) under certain circumstances, but more Canadian participants were in favor of always limiting LST (32% vs. 12%; Chi-square: p < 0.001). Finding long-term care placement was considered more challenging by Canadian participants whereas discontinuing LST was much more challenging for German participants.

CONCLUSIONS

Differences were found between two national medical practice settings with respect to physicians' experiences and attitudes about treatment limitation about VS in spite of comparable diagnostic knowledge.
