Abstract

Objectives: Evaluate whether an intervention applied to general practitioners to prevent clinical inertia had an impact on pain, functionality, and health-related quality of life (HRQoL) of patients with hip and/or knee osteoarthritis.

Design: This was a cluster-based, multicentre, prospective, randomized, parallel-group study. Clusters of physicians working were assigned to one of two study groups. Physicians in Group 1 received a training session while those in Group 2 did not.

Setting: Primary Care Health centers representative of the entire Spanish territory.

Participants: 329 general practitioners of primary healthcare centre.

Interventions: The intervention consists of a motivational session to propose a proactive care, based on current recommendations.

Measurements: Visual analogue scale (VAS); functionality (WOMAC scale) and global perception of health by SF-12. Effects were measured in two visits six months apart.

Results: A total of 1361 physicians, and 4076 patients participated in the study. No significant differences were observed in the clinical benefit obtained between patients assigned to Group 1 and Group 2. Nevertheless, a significant improvement was observed in the combined population (Groups 1 + 2) in the VAS (p<0.001), WOMAC (p<0.0001) and SF-12v2 (p<0.001) questionnaires in Visit 2 compared to Visit 1.

Conclusions: The results indicate that, although this specific intervention carried out on physicians did not provide an additional clinical benefit to patients with knee and/or hip osteoarthritis, an increased awareness of the patient's disease through the use of functionality indexes, as well as the mere fact of being observed, seem to improve patient-reported pain, functionality and HRQoL.

Objetivos: Evaluar si una intervención aplicada a médicos de familia para evitar la inercia clínica tuvo un impacto en el dolor, funcionalidad y calidad de vida relacionada con la salud (CVRS) de los pacientes con artritis de cadera y/o rodilla.

Diseño: Estudio de grupos paralelos de cluster, multicéntrico, prospectivo, aleatorizado. Los médicos fueron asignados a 2 grupos, el grupo 1 recibieó una sesión de entrenamiento, el grupo 2, no.

Emplazamiento: Centros de salud representativos del territorio español.

Participantes: Médicos de familia de 329 centros de salud.

Intervenciones: Consistieron en una sesión motivadora para proponer una atención proactiva, basada en recomendaciones actualizadas.

Mediciones principales: Escala analógica visual (EVA); funcionalidad (escala WOMAC) y percepción global de salud mediante SF-12 en 2 visitas separadas por 6 meses.

Resultados: Participaron 1.361 médicos y 4.076 pacientes. No se observaron diferencias significativas en el beneficio clínico obtenido entre los pacientes asignados al grupo 1 y grupo 2. Sin embargo, se observó una mejora significativa en la población total (grupos 1 + 2) en la EVA (p < 0,001), WOMAC (p < 0,0001) y el SF-12V2 (p < 0,001) en la visita 2 en comparación con la visita 1.

Conclusiones: Esta intervención sobre médicos de familia no proporcionó un beneficio clínico adicional a los pacientes. Se observó en ambos grupos una mayor conciencia de la enfermedad del paciente por el uso novedoso de índices de funcionalidad y CVRS, que parece mejorar el dolor percibido, la funcionalidad y la calidad de vida relacionada con la salud.
