The value of a multidisciplinary consensus meeting in achieving agreement on eating disorders diagnosis at a specialized referral center.

OBJECTIVE: This study aimed to evaluate the concordance of eating disorders (EDs) diagnoses within a multidisciplinary team in a specialized hospital unit dedicated to the medical care of ED. METHODS: The study analyzed data from 608 female patients who sought consultation at the Eating Disorders Referral Center between 2017 and 2021. The diagnoses were established according to the DSM-5 criteria by endocrinologists, psychiatrists, and finally confirmed or discussed within a monthly multidisciplinary consensus meeting (MCM). Fleiss' Kappa tests were conducted to assess inter-raters' agreement. RESULTS: Overall, substantial agreement was observed between endocrinologists and psychiatrists and the MCM. A more detailed analysis revealed variations in agreement across different disorders. Certain EDs demonstrated substantial agreement (e.g., anorexia nervosa restrictive subtype), while others approached near-perfect agreement (e.g., binge-eating disorder). In contrast, agreement was fair to poor for anorexia nervosa binge-purge subtype (ANBP) and slight for other specified feeding and ED. A period of temporary disagreement was noted for ANBP, partially attributed to practitioner turnover. An improvement in interdisciplinary agreement was observed for all ED diagnoses by the end of the study period. DISCUSSION: Variations or lower levels of inter-rater agreement may stem from atypical cases that fall on the border between two diagnoses or complex cases, as well as fluctuating symptoms. The progress observed throughout the study can be attributed in part to interdisciplinary learning, particularly facilitated by the MCM. The findings underscore the significance of striving for optimal concordance among different medical specialties to enhance patient care in ED treatment. PUBLIC SIGNIFICANCE: This study scrutinizes the agreement levels of ED diagnoses among endocrinologists and psychiatrists within a multidisciplinary team at an Eating Disorders Referral Center. While substantial overall agreement was achieved, disparities or lower agreement levels were evident for certain diagnoses such as anorexia nervosa binge-purge subtype. However, collaborative meetings led to a progressive enhancement in agreement over time. This research underscores the crucial role of a multidisciplinary team working collectively to ensure precise diagnoses and improved care for patients with EDs.

Systematic review of prospective studies assessing risk factors to predict anorexia nervosa onset.

BACKGROUND: According to case‒control studies, a multitude of factors contribute to the emergence of anorexia nervosa (AN). The present systematic review examines prospective studies specifically designed to evaluate the prediction of AN onset. METHODS: According to the ARMSTAR 2 and PRISMA 2020 checklists, the PubMed, PsycINFO and Cochrane databases were searched. The methodological quality of the studies was assessed with the Downs and Black checklist. RESULTS: Three articles concerning prospective studies of the general population were ultimately included in the review. The methodological quality of these studies was not optimal. Bidirectional amplification effects were observed between risk factors, some of which could have a relative predictive force as low bodyweight or body dissatisfaction. Even if not included according to specified criteria for this systematic review 11 longitudinal studies, with retrospective analysis of AN onset' prediction, were also discussed. None of these studies asserted the predictive value of particular risk factors as low body weight, anxiety disorders or childhood aggression. CONCLUSIONS: To date there are insufficient established data to propose predictive markers of AN onset for predictive actions in pre-adolescent or adolescent populations. Future work should further evaluate potential risk factors previously identified in case‒control/retrospective studies within larger prospective investigations in preadolescent populations. It is important to clearly distinguish predisposing factors from precipitating factors in subjects at risk of developing AN.

Currently health care guidelines for eating disorders do not include proposal of markers to predict the onset of anorexia nervosa. The current work provides a systematic review of the scientific literature concerning this subject. To date only three published studies were designed in a prospective longitudinal way to evaluate potential predictors of anorexia nervosa onset. When taking into account these studies only low bodyweight and body dissatisfaction in early puberty were proposed as predicting elements for further anorexia nervosa development. Meanwhile the prediction precision was calculated for none of them. No other psychological elements were retained or studied. The age range of the population entering the follow up in these studies was too large covering the peak age of anorexia nervosa itself (13­16 years of age). Larger prospective studies including prepubescent individual and evaluating more psychological markers (perfectionism, negative affectivity or negative self-evaluation) or environmental ones are needed.
