RESUMO
BACKGROUND: The World Health Organization (WHO) International Classification of Diseases and Related Health Problems (ICD) is used globally by 194 WHO member nations. It is used for assigning clinical diagnoses, providing the framework for reporting public health data, and to inform the organization and reimbursement of health services. Guided by overarching principles of increasing clinical utility and global applicability, the 11th revision of the ICD proposes major changes that incorporate empirical advances since the previous revision in 1992. To test recommended changes in the Mental, Behavioral, and Neurodevelopmental Disorders chapter, multiple vignette-based case-controlled field studies have been conducted which examine clinicians' ability to accurately and consistently use the new guidelines and assess their overall clinical utility. This manuscript reports on the results from the study of the proposed ICD-11 guidelines for feeding and eating disorders (FEDs). METHOD: Participants were 2288 mental health professionals registered with WHO's Global Clinical Practice Network. The study was conducted in Chinese, English, French, Japanese, and Spanish. Clinicians were randomly assigned to apply either the ICD-11 or ICD-10 diagnostic guidelines for FEDs to a pair of case vignettes designed to test specific clinical questions. Clinicians selected the diagnosis they thought was correct for each vignette, evaluated the presence of each essential feature of the selected diagnosis, and the clinical utility of the diagnostic guidelines. RESULTS: The proposed ICD-11 diagnostic guidelines significantly improved accuracy for all FEDs tested relative to ICD-10 and attained higher clinical utility ratings; similar results were obtained across all five languages. The inclusion of binge eating disorder and avoidant-restrictive food intake disorder reduced the use of residual diagnoses. Areas needing further refinement were identified. CONCLUSIONS: The proposed ICD-11 diagnostic guidelines consistently outperformed ICD-10 in distinguishing cases of eating disorders and showed global applicability and appropriate clinical utility. These results suggest that the proposed ICD-11 guidelines for FEDs will help increase accuracy of public health data, improve clinical diagnosis, and enhance health service organization and provision. This is the first time in the revision of the ICD that data from large-scale, empirical research examining proposed guidelines is completed in time to inform the final diagnostic guidelines.

Background/Objective: The World Health Organization's diagnostic guidelines for ICD-11 mental and behavioural disorders must be tested in clinical settings around the world to ensure that they are clinically useful and genuinely global. The objective is evaluate the inter-rater reliability and clinical utility of ICD-11 guidelines for psychotic, mood, anxiety- and stress-related disorders in Mexican patients. Method: Adult volunteers exhibiting the selected symptoms were referred from the pre-consultation unit of a public psychiatric hospital to an interview by a pair of clinicians, who subsequently assigned independent diagnoses and evaluated the clinical utility of the diagnostic guidelines as applied to each particular case, on the basis of a scale developed for this purpose. Results: 23 clinicians evaluated 153 patients. Kappa scores were strong for psychotic disorders (.83), moderate for stress-related (.77) and mood disorders (.60) and week for anxiety and fear-related disorders (.43). A high proportion of clinicians considered all diagnostic guidelines to be quite to extremely useful as applied to their patients. Conclusions: ICD-11 guidelines for psychotic, stress-related and mood disorders allow adequate inter-rater consistency among Mexican clinicians, who also considered them as clinical useful tools.
Antecedentes/Objetivo: Las guías diagnósticas CIE-11 para trastornos mentales y del comportamiento de la Organización Mundial de la Salud deben ser evaluadas en pacientes reales alrededor del mundo a fin de asegurar que son clínicamente útiles y genuinamente globales. Se evalúa la consistencia inter-evaluadores y la utilidad clínica de las guías para los trastornos psicóticos, afectivos, de ansiedad y relacionados con el estrés en pacientes mexicanos. Método: Voluntarios con síntomas psicóticos, afectivos, de ansiedad o relacionados con el estrés derivados de una unidad de pre-consulta de un hospital psiquiátrico, para una entrevista con una pareja de clínicos, quienes posteriormente asignaron diagnósticos de manera independiente y evaluaron la utilidad clínica de las guías aplicadas a cada caso en particular, con base en una escala desarrollada para este propósito. Resultados: 23 clínicos evaluaron 153 pacientes. Los coeficientes Kappa fueron fuertes para trastornos psicóticos (0,83), moderados para los relacionados con el estrés (0,77) y afectivos (0,60), y débiles para los de ansiedad y relacionados con el miedo (0,43). Una alta proporción de clínicos consideró que las guías eran bastante o extremadamente útiles. Conclusiones: Las guías CIE-11 para dichos trastornos permiten una adecuada consistencia inter-evaluadores en clínicos mexicanos, quienes les consideran herramientas clínicamente útiles.
