A new service model for the treatment of severe anorexia nervosa in the community: the Anorexia Nervosa Intensive Treatment Team

Clinical care for severe and persistent eating disorders in pediatric populations: Perspectives of health professionals

OBJECTIVE

Models of treatment for adults with severe and enduring eating disorders focus on harm reduction and improving quality of life. However, there is a notable gap in the pediatric literature in this area. The current study set out to assess the perspectives of health professionals regarding clinical care for young people (e.g., ages 10-25 years) with severe and enduring eating disorders, and to explore perceptions about appropriate treatment options for these presentations.

METHODS

Health professionals were invited to complete a two-stage online survey about their experiences with clinical care for pediatric eating disorders through Canadian and Australian professional eating disorder networks. Survey 1 included questions about their experiences in supporting individuals with severe and enduring presentations. Participants who completed Survey 2 reviewed clinical vignettes and shared their perspectives about treatment recommendations and models of care, including for a severe and enduring presentation.

RESULTS

A total of 85 clinicians responded to questions on Survey 1 about severe and enduring eating disorder presentations. A portion of these respondents (n = 25) also participated in Survey 2. The majority of respondents to Survey 1 reported providing clinical care for pediatric severe and enduring eating disorder presentations. Amongst respondents to Survey 2, there was low consensus amongst respondents for the clinical care that would be most appropriate for young people with a severe and enduring eating disorder presentation. Numerous challenges in models of care for severe and enduring presentations in pediatric settings were raised in responses on Survey 2, with clinicians sharing their awareness of models focusing on quality of life, while also raising concerns about the appropriateness of these models for young people.

CONCLUSIONS

The preliminary results of this study demonstrate that the majority of clinicians report that they have provided care to young people with severe and enduring presentations. There is a clear need for establishing guidance for clinicians working in pediatric eating disorder settings around models of care focused on quality of life. Engagement with interested parties, including those with lived experience, can clarify the development of terminology and clinical pathways for severe and enduring presentations of pediatric eating disorders.

A mixed methods study of schema modes amongst people living with eating disorders

BACKGROUND

Schema therapy is promising for people with eating disorders, especially those unresponsive to cognitive behavioural therapy. Complex underlying psychological constructs include dysfunctional schemas and maladaptive modes. This study aimed to explore people living with eating disorders' schema modes and their identification with and understanding of their high scoring modes.

METHODS

Sixteen women with enduring eating disorders without prior exposure to schema therapy completed the schema mode inventory for eating disorders short form (SMI-ED-SF), then participated in semi-structured interviews discussing their high scoring modes. Interviews were analysed by thematic analysis.

RESULTS

All participants scored above clinical concern on at least one maladaptive mode and many scored high on multiple modes, most commonly Demanding Mode, Vulnerable Child and Detached Self-Soother. Qualitatively, four themes emerged: 1) Adverse family environments related to (a) trauma and the vulnerable and angry child and (b) unrealistically high standards; 2) Mode effects on (a) everyday life and (b) disordered eating; 3) Modes are psychologically protective in (a) avoiding emotion by detachment and soothing, (b) people pleasing by compliance and surrender; 4) Help seeking including (a) barriers to recovery from an eating disorder, (b) dissatisfaction with interventions experienced to date, (c) schema therapy as a promising alternative.

DISCUSSION

Participants recognised and identified with their high scoring schema modes. After negative experiences with previous interventions, they considered schema therapy to be a promising alternative that could understand and work on their deeper psychological issues. This suggests that schema modes are a promising way of understanding and working with enduring eating disorders.

Staging models in eating disorders: A systematic scoping review of the literature

Eating Disorders (ED) are characterized by low remission rates, treatment drop-out, and residual symptoms. To improve assessment and treatment of ED, the staging approach has been proposed. This systematic scoping review is aimed at mapping the existing staging models that explicitly propose stages of the progression of ED. A systematic search of PubMed, PsycINFO, Scopus was conducted with the terms staging, anorexia nervosa, bulimia nervosa, binge-eating disorders, eating disorders. Eleven studies met inclusion criteria presenting nine ED staging models, mostly for anorexia nervosa. Three were empirically tested, one of which was through an objective measure specifically developed to differentiate between stages. Most staging models featured early stages in which the exacerbation of EDs unfolds and acute phases are followed by chronic stages. Intermediate stages were not limited to acute stages, but also residual phases, remission, relapse, and recovery. The criteria for stage differentiation encompassed behavioral, psychological, cognitive, and physical features including body mass index and illness duration. One study recommended stage-oriented interventions. The current review underscores the need to empirically test the available staging models and to develop and test new proposals of staging models for other ED populations. The inclusion of criteria based on medical features and biomarkers is recommended. Staging models can potentially guide assessment and interventions in daily clinical settings.

"I Need Someone to Help Me Build Up My Strength": A Meta-Synthesis of Lived Experience Perspectives on the Role and Value of a Dietitian in Eating Disorder Treatment

Dietitians are included in eating disorder (ED) treatment teams for their expertise in nutrition. However, little is known about an individual's experience of dietetic intervention as part of their ED treatment and what they value as part of dietetic care. Therefore, the aim of this review was to synthesise the available qualitative literature to understand the role and value of a dietitian in ED treatment from the perspective of individuals with lived experience. Six databases and Google Scholar were searched and a thematic synthesis and meta-synthesis of fifteen studies were conducted. Four themes were constructed from the data: (1) "guidance and structure"-Provision of nutrition knowledge and skills; (2) "having all my bases covered"-Dietitians as part of a multidisciplinary team; (3) Challenges in nutritional treatment; and (4) "it was my treatment and my recovery"-Person-centred dietetic treatment. Across all identified themes was the cross-cutting theme of a shared treatment journey between the dietitian and the individual receiving treatment. These findings support dietitians having a role that is not limited only to the provision of nutrition treatment in ED care and illustrates the importance of dietitians engaging with clients by centring on the individual's needs and preferences. Further understanding helpful dietetic treatment components and identifying gaps in training is needed to develop these broader roles for dietetic care.

Intensive community and home-based treatments for eating disorders: a scoping review study protocol

INTRODUCTION

Institutionally based intensive treatment modalities (inpatient, day patient and residential treatments) for eating disorders (EDs) are associated with high treatment costs and significant challenges for patients and carers, including access difficulties and disruption to daily routines. Intensive community and home-based treatments have been suggested as alternatives to institutionally based intensive treatments for other severe mental illnesses, with promising clinical, social and health economic outcomes. The possible advantages of these treatments have been proposed for EDs, but this emerging area of research has not yet been systematically investigated. This scoping review aims to map the available literature on intensive community and home treatments for EDs, focusing on their conceptualisation, implementation and clinical outcomes.

METHODS

This proposed scoping review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol extension for Scoping Reviews checklist and the Joanna Briggs Institute Reviewer's Manual. This review will include any peer-reviewed study concerning intensive community and home-based treatments for any EDs, with no restrictions on geographical context or study design. Grey literature will also be considered. The literature search will be conducted in four databases: PubMed, PsycInfo, MEDLINE and Web of Science. Two researchers will independently screen the titles, abstracts and text of the returned articles for eligibility. Data charting and analysis will consist of a narrative description of the included studies, quantitative and qualitative findings relative to the aims of this scoping review. Gaps in the literature will be highlighted to inform future research, clinical practice, and policy.

ETHICS AND DISSEMINATION

Ethical approval is not required as all data are available from public sources. The results of this scoping review will be disseminated through peer-reviewed publication, conference presentation, and social media.

Severe and enduring anorexia nervosa: Update and observations about the current clinical reality

Several objectives underlie the current article. First, to review historical diagnostic issues and clinical strategies for treating SE-AN. Second, to provide an overview of recent evidence informed strategies and clinical innovations for the treatment of SE-AN. Third, based on the authors' collective clinical and research experience, we offer eight observations that we believe capture the current clinical experience of patients with SE-AN. Some of these observations represent empirically testable hypotheses, but all are designed to generate a meaningful discussion about the treatment of this group of individuals with eating disorders. Finally, we hope to call clinicians, scientists, professional organizations, advocates, and policy makers to action to attend to critical issues related to the care of individuals with SE-AN. We believe that an international discussion could clarify areas of need for these patients and identify opportunities for clinical innovation that would enhance the lives of individuals with SE-AN and their families.

Reducing the burden of suffering from eating disorders: Unmet treatment needs, cost of illness, and the quest for cost-effectiveness

Eating disorders are serious mental disorders as reflected in significant impairments in health and psychosocial functioning and excess mortality. Despite the clear evidence of clinical significance and despite availability of evidence-based, effective treatments, research has shown a paradox of elevated health services use and, yet, infrequent treatment specifically targeting the eating disorder (i.e., high unmet treatment need). This review paper summarizes key studies conducted in collaboration with G. Terence Wilson and offers an update of the research literature published since 2011 in three research areas that undergirded our collaborative research project: unmet treatment needs, cost of illness, and cost-effectiveness of treatments. In regards to unmet treatment needs, epidemiological studies find that the number of individuals with an eating disorder who do not receive disorder-specific treatment continues to remain high. Cost-of-illness show that eating disorders are associated with substantial financial burdens for individuals, their family, and society, yet comprehensive examination of costs across public sectors is lacking. Cost measures vary widely, making it difficult to draw firm conclusions. Hospitalization is a major driver of medical costs incurred by individuals with an eating disorder. Only a handful of cost-effectiveness studies have been conducted, leaving policy makers with little information on which to base decisions about allocation of resources to help reduce the burden of suffering attributable to eating disorders.

The patient experience of illness, treatment, and change, during intensive community treatment for severe anorexia nervosa

This study explores experiences of intensive community treatment, illness, and change among patients with severe anorexia nervosa (sAN), particularly seeking to understand the processes involved in change and inability to change. A qualitative design with purposive semi-stratified sampling, using semi-structured interviews and interpretive phenomenological analysis, investigated in detail the experiences of five participants. Participants all had sAN at the start of treatment and represented a spectrum of outcomes from deterioration to full recovery. Six super-ordinate themes emerged from the analysis: treatment experience, function of anorexia, self-criticism versus self-acceptance, isolation versus connection, hopelessness versus hope, and stuckness versus change. Results describe the valued function of the illness, barriers to change, the lengthy struggle for change, and how this can be supported by intensive community-based treatment. Necessary ingredients in the process of change, arising from the analysis, are proposed. We conclude that the experiences of these patients reflect the particular functions of AN for each individual, and that both clinical deterioration and full recovery can occur with prolonged intensive community treatment.

The medical risks of severe anorexia nervosa during initial re-feeding and medical stabilisation

BACKGROUND & AIMS

Objective evidence about the risks associated with anorexia nervosa and how to manage them, is limited. The aim of this study is to describe the medical risk profile, management and outcomes of a cohort of patients with severe anorexia nervosa (sAN) during medical stabilisation treatment.

METHODS

Retrospective analysis of case records gathered medical risk data for a 90 day high risk period, on 65 patients with sAN admitted to two specialist services. Prospectively established definitions of medical risk variables and significant complications were applied to the data to describe the risk profiles and outcomes.

RESULTS

Amongst this population with an average initial BMI of 12.8 kg/m², 74% developed no significant medical complications. Oral re-feeding over 60 days achieved an increase in mean BMI to 14.4 kg/m² and mean weight gain of 4 kg. No patients developed severe hypophosphatemia (<0.45 mmol/L) or any other indicators of a re-feeding syndrome. All the medical complications that arose were temporary.

CONCLUSIONS

Initial re-feeding and medical stabilisation of patients with severe AN can be managed safely in specialist inpatient and community settings with slow re-feeding. Although the prevalence of complications was shown to be low, slight worsening of medical risk markers and increased incidence of complications did occur during initial re-feeding. The limited comparable published data appears to support slower rates of re-feeding, showing fewer abnormal results and complications. There is however a need for a definitive prospective multi-centre observational cohort study to investigate risks factors, and the effects of treatment on medical outcomes, in a large sample with varied rates of re-feeding.

An Integrative Bio-Psycho-Social Theory of Anorexia Nervosa

The need for novel approaches to understanding and treating anorexia nervosa (AN) is well recognized. The aim of this paper is to describe an integrative bio-psycho-social theory of maintaining factors in AN. We took a triangulation approach to develop a clinically relevant theory with face validity and internal consistency. We developed theoretical ideas from our clinical practice and reviewed theoretical ideas within the eating disorders and wider bio-psycho-social literature. The synthesis of these ideas and concepts into a clinically meaningful framework is described here. We suggest eight key factors central to understanding the maintenance and treatment resistance of anorexia nervosa: genetic or experiential predisposing factors; dysfunctional feelings processing and regulation systems; excessive vulnerable feelings; 'feared self' beliefs; starvation as a maladaptive physiological feelings regulation mechanism; maladaptive psychological coping modes; maladaptive social behaviour; and unmet physical and psychological core needs. Each of these factors serves to maintain the disorder. The concept of universal physical and psychological core needs can provide an underpinning integrative framework for working with this distinctly physical and psychological disorder. This framework could be used within any treatment model. We suggest that treatments which help address the profound lack of trust, emotional security and self-acceptance in this patient group will in turn address unmet needs and improve well-being.

KEY PRACTITIONER MESSAGE

The concept of unmet physical and psychological needs can be used as an underlying integrative framework for understanding and working with this patient group, alongside any treatment model. A functional understanding of the neuro-biological, physiological and psychological mechanisms involved in anorexia nervosa can help patients reduce self-criticism and shame. Fears about being or becoming fat, greedy, needy, selfish and unacceptable ('Feared Self') drive over-compensatory self-depriving behaviour ('Anorexic Self'). Psychological treatment for anorexia nervosa should emphasize a focus on feelings and fostering experiences of acceptance and trust. Treatment for patients with anorexia nervosa needs to be longer than current clinical practice.

Treatment of patients with severe and enduring eating disorders

PURPOSE OF REVIEW

Severe and enduring eating disorder is a new concept to the field that has potential to aid assessment and inform treatment. The aim of this review is to report recent developments in the conceptualization and treatment of people with severe and enduring eating disorder.

RECENT FINDINGS

A systematic search identified 28 included papers. These addressed conceptualization of recovery and staging models (4 studies), clinical care, presentations and treatment experiences (7 studies), four new randomized controlled trials of treatment (9 studies), two open trials of novel approaches (2 studies) and problems of treatment resistance and involuntary care (6 studies).

SUMMARY

The staging model appears to have validity and clinical utility in anorexia nervosa, but this is less clear in other eating disorders. Most literature on treatment, including new randomised controlled trials, is on underweight individuals, and there is a small literature on emerging psychological therapies that may improve outcomes. There is an expectation that with better treatment engagement, there may also be a reduced need for involuntary interventions.
