RESUMO
El HAQ se considera el estándar de oro para la evaluación de la capacidad funcional en pacientes con artritis reumatoide (AR), ya que realiza una valoración global de la misma. Con el objetivo de evaluar la incapacidad funcional de la mano en pacientes ancianos con osteoartritis, Baron et al. utilizaron una versión modificada del HAQ al que llamaron «HAQ-UP». Este instrumento no ha sido validado en pacientes con AR. Objetivo: Validar la versión argentina del HAQ-UP en pacientes con AR. Métodos: Estudio de corte transversal. Se incluyeron pacientes consecutivos ≥18años con diagnóstico de AR (ACR/EULAR 2010). Se consignaron datos demográficos y características de la enfermedad. Se completaron los cuestionarios HAQ-A, HAQ-UP-A, FIHOA y Quick-DASH. Se estableció la reproducibilidad del cuestionario. Resultados: Se incluyeron 100 pacientes, 83% mujeres, edad media 57,9años (DE11,6). La prueba alfa de Cronbach fue de 0,94. La correlación intra-ítem no evidenció preguntas redundantes. El HAQ-UP-A mostró excelente correlación con HAQ-A (r=0,93), FIHOA (r=0,89) y Quick-DASH (r=0,91). También presentó buena correlación con DAS28-VSG (r=0,68) y otros índices compuestos de actividad, así como con otros parámetros de la enfermedad. No se evidenció correlación del HAQ-UP-A con tiempo de evolución de la AR. La reproducibilidad del cuestionario fue de 0,82. La regresión lineal múltiple ajustada por edad y sexo mostró como principales determinantes del HAQ-UP-A a la evaluación global de la enfermedad por parte del paciente seguido por la presencia de rigidez matinal. El HAQ-UP-A resultó ser confiable, válido y reproducible en pacientes con AR, constituyendo una herramienta útil en la evaluación de la capacidad funcional de los miembros superiores.(AU)
HAQ is considered the gold standard for the evaluation of functional capacity in patients with rheumatoid arthritis (RA), even though it does not focus on any particular anatomical region. With the objective of assessing functional disability of the hand in elderly patients with osteoarthritis, Baron et al. used a modified version of the HAQ which was calculated as the mean value for the categories mostly involving the upper extremities and named it HAQ-UP. This instrument has not been validated in patients with RA. Objective: To validate HAQ-UP-Argentine version in patients with RA. Methods: Cross-sectional study. Consecutive patients ≥18years with diagnosis of RA (ACR/EULAR 2010) were included. Socio-demographic data and RA characteristics were recorded. Questionnaires were administered: HAQ-A, HAQ-UP-A, FIHOA, Quick-DASH. The reproducibility of the questionnaire was assessed. Results: A total of 100 patients were included, 83% women, mean age 57.9years (SD 11.6). Cronbach's alpha test was 0.94. The intra-item correlation did not show redundant questions. HAQ-UP-A showed excellent correlation with HAQ-A (r=.93); FIHOA (r=.89) and Quick-DASH (r=.91). It also showed good correlation with DAS28-ESR (r=.68) and other composite disease activity indices as well as with other parameters of the disease. There was no correlation between HAQ-UP-A and disease duration. The reproducibility of the questionnaire was 0.82. Multiple linear regression adjusted for age and sex showed patient global VAS as the main determinant of HAQ-UP-A, followed by the presence of morning stiffness. Conclusion: HAQ-UP-A was found to be reliable, valid and reproducible in patients with RA, representing a useful tool for the evaluation of the functional capacity of the upper limbs in these patients.(AU)
