[Evaluation of patient satisfaction after stroke rehabilitation program. Validation study for the Spanish version of the Satisfaction Pound Scale]. / Evaluación de la satisfacción con el programa de rehabilitación tras el ictus: validación de la versión española de la Pound Satisfaction Scale.

BACKGROUND AND OBJECTIVE: The Satisfaction Pound Scale is a specific questionnaire to evaluate satisfaction with the rehabilitation program after a stroke. The aim of this study was to adapt this scale to Spanish and to evaluate its metric characteristics. METHOD: The adaptation included translation and back-translation methods. Metric characteristics were evaluated in 74 patients, all of whom were administered the Satisfaction Pound Scale and the Short Form 36 (SF-36). The statistical model was tested by confirmatory factor analysis (CFA). Reliability was determined through Cronbach alpha coefficient and a test-retest procedure. Construct validity was assessed by means of correlations between the satisfaction scale and the SF-36. RESULTS: Adjustment indicators in the CFA were very good. Reproducibility test showed correlations higher than 0.85, and all correlations between SF-36 dimensions and the satisfaction scale were lower than 0.2, in accordance with the hypotheses raised. CONCLUSIONS: The Spanish version of the Satisfaction Pounds Scale is reliable and valid, therefore it is a useful tool to assess satisfaction with the post-stroke rehabilitation program in our area.

Fundamento y objetivo. La Escala de Satisfacción de Pound es un cuestionario específico para evaluar la satisfacción con la rehabilitación seguida tras el ictus. Nuestro objetivo fue adaptar esta escala al español y evaluar sus características métricas. Método. La adaptación se realizó por traducción-retrotraducción. Las características métricas se evaluaron en 74 pacientes con la Escala de Satisfacción de Pound y el cuestionario de salud percibida Short Form 36 (SF-36). El modelo de medida se evaluó mediante análisis factorial confirmatorio (AFC); la fiabilidad, a partir de la consistencia interna y la reproducibilidad (test-retest); la validez de constructo se estudió mediante las correlaciones entre la escala de Pound y el SF-36. Resultados. Los indicadores de bondad de ajuste del AFC fueron muy buenos. En el estudio test-retest los coeficientes de correlación intraclase fueron>0,85. Todas las correlaciones entre las dimensiones del SF-36 y el cuestionario de satisfacción fueron<0,2. Conclusiones. La versión en español de la Escala de Satisfacción de Pound administrada telefónicamente es fiable y válida, resultando útil para evaluar la satisfacción con la rehabilitación seguida tras el ictus (AU)

Entrainment from the para-Hisian region for differentiating atrioventricular node reentrant tachycardia from orthodromic atrioventricular reentrant tachycardia.

AIMS: The difference between the stimulus-atrial and ventriculo-atrial intervals (SA-VA) and between the post-pacing interval and the tachycardia cycle length (PPI-TCL) during entrainment from the right ventricular apex distinguishes atrioventricular node reentrant (AVNRT) from orthodromic atrioventricular reentrant tachycardia (AVRT). We hypothesized that these features still apply when entrainment is performed from the para-Hisian region. METHODS AND RESULTS: Forty-seven supraventricular tachycardias (34 AVNRT/13 AVRT) were included. The SA-VA and PPI-TCL were obtained in all patients by using two right-sided diagnostic catheters. In 24 of them, these measurements were also performed upon His-bundle capture during entrainment. A paced QRS widening of >or=40 ms during entrainment, when compared with the tachycardia QRS width, identified absence of His-bundle capture, P < 0.001. A SA-VA >75 ms distinguished AVNRT from AVRT, P < 0.001 (sensitivity/specificity 97%/100%). A PPI-TCL >100 ms was diagnostic of AVNRT, P < 0.001 (sensitivity/specificity 97%/92%). Upon His-bundle capture, the SA-VA and PPI-TCL shortened in AVNRT (121 +/- 23 to 66 +/- 24 ms; 139 +/- 30 to 85 +/- 31 ms, respectively, P < 0.001) and no longer differentiated AVNRT from AVRT. CONCLUSION: Para-Hisian entrainment without His-bundle capture distinguishes AVNRT from AVRT with the advantage of using only two diagnostic catheters.
