Descripción de los resultados y costes de una intervención preventiva a nivel respiratorio en el anciano institucionalizado: ensayo controlado aleatorizado / Cost-consequence analysis of respiratory preventive intervention among institutionalized older people: Randomized controlled trial

Introducción. En el anciano institucionalizado con limitación funcional se evidencia una mayor reducción de la funcionalidad de la musculatura respiratoria (MR). Los objetivos de este estudio son evaluar los resultados y costes de una intervención de entrenamiento de la MR mediante Pranayama en población anciana institucionalizada con limitación funcional. Material y métodos. Estudio controlado aleatorizado desarrollado en ancianos institucionalizados con limitación para la deambulación (n = 54). La intervención consistió en el entrenamiento de la MR mediante Pranayama, durante 6 semanas (5 sesiones/semana). Los resultados se midieron en relación con la función de la MR mediante las presiones inspiratoria y espiratoria máximas y la ventilación máxima voluntaria, en 4 tiempos. También se valoró la satisfacción percibida por el grupo experimental (GE) a través de un cuestionario ad hoc. Se estimaron los costes directos e indirectos de la intervención desde la perspectiva social. Resultados. El GE reveló una mejora significativa de la fuerza (presiones inspiratoria y espiratoria máximas) y de la resistencia (ventilación máxima voluntaria) de la MR. Además, un 92% del GE refirió una satisfacción alta. Los costes sociales totales, directos e indirectos, ascendieron a 21.678 Euros. Conclusiones. Esta evaluación revela que los resultados en términos de la función de la MR son significativos, que la intervención es bien tolerada y valorada por el residente, y los costes de la intervención son moderados (AU)

Introduction. The institutionalized elderly with functional impairment show a greater decline in respiratory muscle (RM) function. The aims of the study are to evaluate outcomes and costs of RM training using Pranayama in institutionalized elderly people with functional impairment. Material and methods. A randomized controlled trial was conducted on institutionalized elderly people with walking limitation (n = 54). The intervention consisted of 6 weeks of Pranayama RM training (5 times/week). The outcomes were measured at 4 time points, and were related to RM function: the maximum respiratory pressures and the maximum voluntary ventilation. Perceived satisfaction in the experimental group (EG) was assessed by means of an ad hoc questionnaire. Direct and indirect costs were estimated from the social perspective. Results. The GE showed a significant improvement related with strength (maximum respiratory pressures) and endurance (maximum voluntary ventilation) of RM. Moreover, 92% of the EG reported a high satisfaction. The total social costs, direct and indirect, amounted to Euros 21,678. Conclusions. This evaluation reveals that RM function improvement is significant, that intervention is well tolerated and appreciated by patients, and the intervention costs are moderate (AU)
