Validación del cuestionario COPCORD para detección de enfermedades reumáticas CUENCA - ECUADOR

Objetivo: Validar la adaptación cultural del ins-trumento (Community Orientade Programm in the Rheumatic Diseases) COPCORD para de-tectar malestares músculo-esqueléticos y en-fermedades reumáticas en la población del cantón Cuenca.Metodología: Validación transcultural del cues-tionario COPCORD y aplicación en la comuni-dad, para identificar síntomas reumáticos. Un médico reumátologo revisó a las personas para definir el diagnóstico.Se realizó análisis estadístico descriptivo de cada una de la variables; se midió el alfa de Chronbach, análisis de prueba de tamizaje (sensibilidad, especificidad, valor predictivo positivo y curvas roc). Resultados: Participaron 201 personas, 106 del área urbana y 95 del área rural. El 67,6% co-rrespondió a mujeres con una edad promedio 50,3 años, con escolaridad 7,5 años. El 57,7% reportó dolor músculo-esquelético, con una in-tensidad de 5,8 por EVA; al comparar el cues-tionario COPCORD con la evaluación clínica del reumatólogo, se observó una sensibilidad del 83,72, especificidad de 61,14%, razón de verosimilitud de 2,18 y área bajo la curva de 0,72; con una alfa de Cronbach de 0,7 para las características del dolor y 0,9 para capaci-dad funcionalObjective: To validate the cultural adaptation of the instrument (Community Orientate Pro-gram in the Rheumatic Diseases) COPCORD to detect musculoskeletal pain and rheumatic diseases in the population of Cuenca.Methodology: A COPCORD transcultural ques-tionnaire validation and its application were made in the community to identify rheumatic symptoms. A rheumatologist doctor checked people to define the diagnosis. A descriptive statistical analysis of each variable was per-formed. Chronbach alpha, analysis screening test (sensitivity, specificity, and positive predic-tive value and roc curves) was measured.Results: A total of 201 people participated, 106 in urban areas and 95 in rural areas. The 67.6% were women with an average age of 50.3 years with 7.5 years in school. The 57.7% reported musculoskeletal pain with an inten-sity of 5.8 for VSA. Comparing the COPCORD questionnaire with the clinical assessment of the rheumatologist an 83.72% of sensitivity, was observed, specificity of 61.14%, probability of 2.18 and area under the curve of 0.72; with a Cronbach’s alpha of 0.7 for pain characteris-tics and 0,9 for functional capacity.Conclusion: The COPCORD questionnaire is valid for using in rural and urban populations in Ecuador; it demonstrated good performance as a screening test

Prevalence of musculoskeletal disorders and rheumatic diseases in Cuenca, Ecuador: a WHO-ILAR COPCORD study

The aim of this study was to determine the prevalence of musculoskeletal pain and rheumatic diseases in subjects over 18 years of age from the canton of Cuenca, Ecuador. Cross-sectional analytical community-based study was conducted in subjects over 18 years of age using the validated Community-Oriented Program for the Control of Rheumatic Diseases (COPCORD) questionnaire. Random sampling was used. The questionnaire was administered by standardized health workers. Subjects were visited house by house. Subjects positive for musculoskeletal (MSK) pain in the last 7 days and at some point in life were assessed by rheumatologists to confirm the diagnosis. A total of 4877 subjects participated, with an average age of 42.8 (SD 18.8) years of age; 59.7 % were women; 69.7 % lived in urban areas. 32.5 % reported MSK pain in the last 7 days and 45.7 % at some point in life. The prevalence of knee osteoarthritis was 7.4 %, hand osteoarthritis 5.3 %, low back pain 9.3 %, rheumatoid arthritis 0.8 %, fibromyalgia 2 %, gout 0.4 %, and lupus 0.06 %. Subjects from rural areas reported experiencing more MSK pain in the last 7 days and at some point in life, lower income, poorer health-care coverage, and increased physical activity involving repetitive tasks such as lifting weights or cooking with firewood. MSK pain prevalence was high. Osteoarthritis and low back pain were the most common diseases. Age, sex, physical activity, repetitive tasks, living in a rural area, and lack of health-care coverage were found to be associated with MSK pain
