Ethical concerns in caring for persons with anorexia nervosa: content analysis of a series of documentations from ethics consultations

BACKGROUND

Caring for patients with anorexia nervosa (AN) is associated with high levels of moral distress among healthcare professionals. The main moral conflict has been posited to be between applying coercion to prevent serious complications such as premature death and accepting treatment refusals. However, empirical evidence on this topic is scarce.

METHODS

We identified all 19 documentations of ethics consultations (ECs) in the context of AN from one clinical ethics support service in Switzerland. These documentations were coded with a sequential deductive-inductive approach and the code system was interpreted in a case-based manner. Here, we present findings on patient characteristics and ethical concerns.

FINDINGS

The ECs typically concerned an intensely pretreated, extremely underweight AN patient endangering herself by refusing the proposed treatment. In addition to the justifiability of coercion, frequent ethical concerns were whether further coerced treatment aimed at weight gain would be ineffective or even harmful, evidencing uncertainty about beneficence and non-maleficence and a conflict between these principles. Discussed options included harm reduction (e.g. psychotherapy without weight gain requirements) and palliation (e.g. initiating end-of-life care), the appropriateness of which were ethical concerns in themselves. Overall, nine different types of conflicts between or uncertainties regarding ethical principles were identified with a median of eight per case.

CONCLUSIONS

Ethical concerns in caring for persons with AN are diverse and complex. To deal with uncertainty about and conflict between respect for autonomy, beneficence and non-maleficence, healthcare professionals consider non-curative approaches. However, currently, uncertainty around general justifiability, eligibility criteria, and concrete protocols hinders their adoption.

Severe and enduring anorexia nervosa and the proposed "Terminal anorexia" category: an expanded meta synthesis

This updated meta-synthesis explores further dimensions of the lived experience of severe and enduring anorexia nervosa (SE-AN) since recent contention regarding proposed "terminal anorexia nervosa (T-AN)". The paper aims to update the original synthesis and to situate participant responses to the category of "T-AN". Thus, extending the proposed conceptualization of the SE-AN experience. A systematic search identified published scholarship (between August 2022 and July 2023), derived from five bibliographic databases. A comprehensive methodology combining Interpretative Phenomenological Analysis and a meta-ethnographic framework enabled the synthesis of meta-themes across 9 new studies. These meta-themes were mapped onto the primary synthesis to further develop upon the earlier LE conceptualization of SE-AN. Nine extracted papers expanded the voices to 447 people within 45 studies. All papers affirmed and enriched the previous themes, and a novel theme was generated from the recent papers. The new theme, "walking on a knife's edge, caught between worlds", informed an expanded conceptualization of SE-AN, termed the Web of Hope. Thus, demonstrating how participants held onto hope in the face of the SE-AN experience. Death, dying and "terminality", were notably absent in the 36 papers in the previous meta-synthesis. Since the proposal of the category of "terminal anorexia" in 2022, studies on the lived experience of SE-AN increasingly focused on how people hold onto hope alongside SE-AN. The findings further drive the field to reflect on therapeutic interventions, labelling and diagnosis, in the face of unknowns, on the premise of "first, do no harm".

Inclusion of the severe and enduring anorexia nervosa phenotype in genetics research: a scoping review

BACKGROUND

Anorexia nervosa has one of the highest mortality rates of all mental illnesses. For those who survive, less than 70% fully recover, with many going on to develop a more severe and enduring phenotype. Research now suggests that genetics plays a role in the development and persistence of anorexia nervosa. Inclusion of participants with more severe and enduring illness in genetics studies of anorexia nervosa is critical.

OBJECTIVE

The primary goal of this review was to assess the inclusion of participants meeting the criteria for the severe enduring anorexia nervosa phenotype in genetics research by (1) identifying the most widely used defining criteria for severe enduring anorexia nervosa and (2) performing a review of the genetics literature to assess the inclusion of participants meeting the identified criteria.

METHODS

Searches of the genetics literature from 2012 to 2023 were performed in the PubMed, PsycINFO, and Web of Science databases. Publications were selected per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The criteria used to define the severe and enduring anorexia nervosa phenotype were derived by how often they were used in the literature since 2017. The publications identified through the literature search were then assessed for inclusion of participants meeting these criteria.

RESULTS

most prevalent criteria used to define severe enduring anorexia nervosa in the literature were an illness duration of ≥ 7 years, lack of positive response to at least two previous evidence-based treatments, a body mass index meeting the Diagnostic and Statistical Manual of Mental Disorders-5 for extreme anorexia nervosa, and an assessment of psychological and/or behavioral severity indicating a significant impact on quality of life. There was a lack of consistent identification and inclusion of those meeting the criteria for severe enduring anorexia nervosa in the genetics literature.

DISCUSSION

This lack of consistent identification and inclusion of patients with severe enduring anorexia nervosa in genetics research has the potential to hamper the isolation of risk loci and the development of new, more effective treatment options for patients with anorexia nervosa.

Refusal of Treatment for Anorexia Nervosa: Mental Health Professionals' Opinion on Willingness and Role Stress

INTRODUCTION

The hospitalisation of patients with anorexia nervosa poses an important bioethical quandary and can generate stress for the healthcare professionals. Our goal was to know and analyse the opinion of mental health professionals on some conditions for applying the involuntary hospitalisation of patients with anorexia nervosa.

METHODS

Cross-sectional descriptive observational study on a sample of 270 mental health professionals, using an ad hoc questionnaire with scores ranging from 0 to 10.

RESULTS

The professionals state that, in some cases, the patient accepts admission reluctantly: 7.74 (95% CI, 7.55-7.93). In the event of physical risk, it is difficult for them to combine respect for the patient's autonomy and the duty of care: 6.06 (95% CI, 5.70-6.41) and the relationship with the patient is largely oriented to convince them: 7.18 (95% CI, 6.91-7.46). They do not decide on the suitability of the participation of non-medical staff in the decision: 5.13 (95% CI, 4.75-5.52), or if the indication should correspond to someone other than the doctor in charge of their care: 4.79 (95% CI, 4.39-5.19). They reject the possibility of conscientious objection: 4.05 (95% CI, 3.68-4.41).

CONCLUSIONS

Mental health professionals are subject to ambiguous work demands, which affects their care dynamics.
