RESUMO
OBJETIVO: Valorar el riesgo de declive funcional (DF) mediante varias escalas de predicción. MATERIAL Y MÉTODOS: Estudio multicéntrico, observacional y corte transversal, dirigido a una población de 70 años o más del área de salud de Toledo. Se excluyeron los pacientes institucionalizados, terminales y dependientes para 3 o más actividades básicas de la vida diaria. La muestra (480 pacientes), fue calculada para: prevalencia DF estimada del 15%, precisión 2%, nivel de confianza 95 y 10% de pérdidas estimadas. Muestreo estratificado, primero por conglomerados (centros de salud) y posteriormente muestreo sistemático (1/15) por listado de pacientes ordenados por edad. Tasa de respuesta: 98%. VARIABLES: Sociodemográficas, de morbilidad, cuestionarios para evaluar la capacidad funcional para las actividades básicas (índice de Katz) e instrumentales (índice de Lawton-Brody) de la vida diaria y reglas de predicción de riesgo de DF (SHERPA, TRST, ISAR-PC e Inouye). Aprobado por el Comité Ético de Investigación Clínica de Toledo. RESULTADOS: Media de edad: 77,94 (DS: 6,27) años, el 54,4% mujeres. Media de enfermedades: 4,38 (DS: 2,17) y de fármacos: 5,57 (DS: 3,35). Riesgo de DF según las reglas de predicción: SHERPA: 32,7% (IC95%: 28,52-36,88) (riesgo leve: 17,2% [IC95%: 13,83-20,57]; moderado: 9,7% [IC95%: 7,06-12,34] y alto: 5,8% [IC95%: 3,72-7,88]); TRST: 42% (IC95%: 37,6-46,4); ISAR-PC: 75,4% (IC95%: 71,14-78,86); Inouye: 49,3% (IC95% 44,84-53,76) (riesgo medio: 44,5% [IC95%: 40,07-48,93] y riesgo alto: 4,8% [IC95%: 2,89-6,71]). CONCLUSIONES: Porcentaje importante de pacientes en riesgo de DF, pero gran variabilidad entre las distintas reglas. En general, el riesgo es inferior al encontrado en otros estudios, siendo necesario validar nuevas reglas adaptadas a nuestro medio
OBJECTIVE: To assess the risk of functional decline (DF) by using several prediction scales. MATERIAL AND METHODS: A multicentre, observational, cross-sectional study was conducted on a population of 70 years or more in the health area of ??Toledo. Institutionalised, terminal ill, and patients dependent for three or more basic activities of daily life, were excluded. The sample (480 patients) was calculated for an estimated DF prevalence of 15%, accuracy 2%, confidence level 95%, and 10% of estimated losses. Stratified sampling; first by conglomerates (Health Centres) and then systematic sampling (1/15) by list of patients ordered by age. Response rate: 98%. VARIABLES: Sociodemographic, morbidity, questionnaires to assess the functional capacity for basic activities (Katz index), and tools (Lawton-Brody index) of daily life and risk prediction rules of DF (SHERPA, TRST, ISAR-PC and Inouye). Approved by the Clinical Research Ethics Committee of Toledo. RESULTS: The mean age was 77.94 (SD: 6.27), with 54.4% women. Mean number of illnesses: 4.38 (SD: 2.17) and drugs: 5.57 (SD: 3.35). Risk of DF according to the prediction rules: SHERPA: 32.7% (95% CI: 28.52-36.88) (slight risk: 17.2% [95% CI: 13.83-20.57]; moderate: 9.7% [95% CI: 7.06-12.34] and high: 5.8% [95% CI: 3.72-7.88]); TRST: 42% (95% CI: 37.6-46.4); ISAR-PC: 75.4% (95% CI: 71.14-78.86); Inouye: 49.3% (95% CI: 44.84-53.76) (mean risk: 44.5% [95% CI: 40.07-48.93], and high: risk 4.8% [95% CI: 2.89-6.71]). CONCLUSIONS: A significant percentage of patients are at risk of DF, but there is a wide variation between the different rules. In general, the risk is lower than that found in other studies, and it is necessary to validate new rules adapted to our environment
