Validation of the Spanish version of the modified Harris scoreValidación de la versión española de la escala de Harris modificada

Abstract

Background and objectives Modified Harris Hip Score (HHS) is one of the most used scales in the assessment of patients with hip pathology. Although a Spanish cross-cultural adaptation has been recently published, there are many studies supporting its validity yet. Therefore, the aim of this study is to validate the newly adapted Spanish version of the HHS (ES-EHM), comparing it with the WOMAC scale. Materials and methods The ES-EHM scale was applied to 100 patients who underwent a total hip replacement, in three different situations: (1) prior to surgery (pre-surgical ES-EHM), (2) after surgery, with at least 2 years of follow up (after surgery ES-EHM), and (3) 6 months after the postsurgical registration (final ES-EHM). WOMAC questionnaire was also applied once. We analysed data of scale main score, pain score, function-related score as well as the mean of pre-surgical, postsurgical and final postsurgical ES-EHM scale, in both the ES-EHM and the WOMAC scales. Parameters of reliability, validity and sensitivity to change were obtained. Results Clinically relevant improvement was observed (46.55 points) when comparing pre-surgical and post-surgical ES-EHM scores. However, no differences between postsurgical and final ES-EHM were detected. Even so, strong correlation was obtained between the following: (1) postsurgical ES-EHM and final ES-EHM scores, (2) ES-EHM and WOMAC scores, and (3) pain and function-related parameters of ES-EHM and WOMAC scores. Standardised response mean (SRM) was 2.99, test–retest reliability expressed by the intraclass correlation coefficient was 0.90 and Cronbach index 0.95. Conclusions The Spanish cross-cultural adaptation of the EHM scale shows to be reliable, valid and sensitive to change. Thus, the Spanish medical staff will be able to apply the ES-EHM scale with good scientific support.

Antecedentes y objetivos La escala de Harris modificada (EHM) es una de las herramientas más utilizadas para valorar pacientes con patología de cadera. A pesar de contar con una adaptación transcultural al español realizada por Lara et al., no cuenta con estudios que sustenten su validez. Se pretende obtener una validación de la versión adaptada de la EHM (ES-EHM), comparándola con la escala WOMAC. Materiales y métodos La ES-EHM se aplicó a 100 pacientes operados de prótesis total de cadera: (1) previamente a la cirugía (ES-EHM prequirúrgica), (2) dos años tras la cirugía (ES-EHM posquirúrgica) y (3) seis meses después de la aplicación de la ES-EHM posquirúrgica (ES-EHM final). Se aplicó también, en una ocasión, el cuestionario WOMAC. Se compararon las medias de la ES-EHM prequirúrgica, posquirúrgica y final, así como la totalidad y los parámetros de dolor y función de la ES-EHM con la escala WOMAC. Se obtuvieron parámetros de fiabilidad, validez y sensibilidad al cambio. Resultados Al comparar la ES-EHM prequirúrgica y la posquirúrgica, se observó una mejoría clínicamente relevante (46,54 puntos). Al comparar la ES-EHM posquirúrgica y la final, no se detectaron diferencias. Se obtuvo una correlación fuerte entre: (1) la ES-EHM posquirúrgica y la ES-EHM final, (2) ES-EHM y WOMAC y (3) parámetros de dolor y función de la ES-EHM y la WOMAC. El índice de respuesta media estandarizada fue de 2,99, la fiabilidad test-re-test representada por el coeficiente de correlación intraclase de 0,90 y el índice de consistencia interna alfa de Cronbach de 0,95. Conclusiones La adaptación transcultural de la ES-EHM muestra ser fiable, válida y sensible al cambio. Por lo tanto, el personal médico de la población española podrá aplicar la ES-EHM con el respaldo científico y la certeza de estar midiendo los parámetros deseados.
