- Abstract : Background: This paper describes the development and validation of an electronic personal assessment questionnaire for vascular conditions (ePAQ‐VAS) that captures the symptomatology, quality of life and clinically relevant data of patients presenting to vascular services. Methods: A two‐stage survey was conducted in patients attending a tertiary vascular department. Patients completed the ePAQ‐VAS remotely online, or on site using an electronic tablet. In the first stage of the survey, the responses were used to perform confirmatory factor analysis to assess the construct validity and remove redundant items. The internal reliability of disease‐specific scales was investigated. In the second stage of the survey, the acceptability, known‐group validity, test–retest reliability, and responsiveness of ePAQ‐VAS was assessed. Results: In total, 721 patients completed ePAQ‐VAS. Their mean(s.d.) age was 63·5(15·7) years and 468 (64·9 per cent) were men. Some 553 patients (76·7 per cent) completed the questionnaire in clinic and the remainder completed the questionnaire online. The results of the confirmatory factor analysis confirmed the conceptual model for ePAQ‐VAS structure and eliminated six items. Internal reliability was acceptable for all the scales (Cronbach's α greater than 0·7). The test–retest reliability measured by the intraclass correlation coefficient ranged from 0·65 to 0·99. The results showed that the instrument was responsive over time with theAbstract : Background: This paper describes the development and validation of an electronic personal assessment questionnaire for vascular conditions (ePAQ‐VAS) that captures the symptomatology, quality of life and clinically relevant data of patients presenting to vascular services.

The results showed that the instrument was responsive over time with the standardized response mean ranging from 0·69 to 1·60. Conclusion: ePAQ‐VAS is a holistic data‐collection process that is relevant to vascular service users and has potential to contribute to patient‐focused care and the collection of aggregate data for service evaluation.

Métodos: Se llevó a cabo una encuesta en dos fases entre los pacientes atendidos en un servicio de patología vascular de tercer nivel. Los pacientes completaron el cuestionario ePAQ‐VAS a distancia en línea o bien en el centro hospitalario mediante una tableta electrónica. En la primera fase de la encuesta, las respuestas se utilizaron para realizar un análisis factorial de confirmación para evaluar la validez del diseño y eliminar los elementos redundantes. Se investigó la fiabilidad interna de las escalas específicas de la enfermedad. En la segunda fase de la encuesta, se evaluó la aceptabilidad, la validez de grupo conocida, la fiabilidad test‐retest y la capacidad de respuesta del ePAQ‐VAS. Resultados: En total, 721 pacientes completaron el ePAQ‐VAS, la edad media fue de 63, 5 años (DE 15, 7); el 64, 9% eran varones (468); el 76% de los pacientes (553) completaron el cuestionario en la clínica y los pacientes restantes lo hicieron electrónicamente a distancia. Los resultados del análisis factorial de confirmación confirmaron el modelo conceptual para la estructura ePAQ‐VAS y eliminaron seis ítems. La fiabilidad interna fue aceptable para todas las escalas (alfa de Cronbach > 0, 7). La fiabilidad test‐retest medida por el coeficiente de correlación intraclase osciló entre 0, 65‐0, 99. Los resultados mostraron que el instrumento responde con el tiempo con una media de respuesta estandarizada que varía de 0, 69 a 1, 60. Conclusión: El ePAQ‐VAS es un proceso holístico de recopilación de datos que es relevante para los usuarios de servicios de patología vascular y tiene el potencial de contribuir a la atención centrada en el paciente y a la recopilación de datos agregados para la evaluación del servicio. … (more)
