Uso de antipsicóticos en los pacientes con demencia en España: comparación con la prescripción de los inhibidores de la acetilcolinesterasa y de la memantina, y análisis de las asociaciones / Use of antipsychotics in patients with dementia in Spain: Comparison with prescription of acetylcholinesterase inhibitors and memantine and analysis of associations

Objetivo: Se ha analizado la prevalencia de antipsicóticos, inhibidores de la acetilcolinesterasa (IACE) y memantina en pacientes con demencia en España y la influencia de estas asociaciones en su prescripción. Método: Estudio descriptivo, retrospectivo y transversal de la base BIFAP de 2017 en los mayores de 65 años con demencia. Se recogieron las prescripciones de antipsicóticos, los IACE y la memantina. Para los antipsicóticos también se recogieron, la duración del tratamiento y el tiempo desde el diagnóstico de demencia, al de prescripción. Resultados: Se recuperaron 1.327.792 sujetos, 89.464 (6,73%) con demencia. El 31,76% tuvieron prescritos antipsicóticos; los más frecuentes: quetiapina (58,47%), risperidona (21%) y haloperidol (19,34%). Las prescripciones de IACE y memantina fueron más frecuentes en los menores de 84 años y las de antipsicóticos en los mayores de 85 años (p<0,001). Los antipsicóticos se mantuvieron una media de 1.174,5 días. En el 26,4% de los casos se prescribieron aislados, OR: 0,61 (IC 95%: 0,59-0,62), en el 35,85% asociados a IACE, OR: 1,26 (IC 95%: 1,22-1,30) y en el 42,4% a memantina, OR: 1,69 (IC 95%: 1,62-1,78); p<0,000). Desde el diagnóstico de demencia transcurrieron de 461 días (±1.576,5) cuando se prescribieron aislados; 651 días (±1.574,25) asociados a IACE y 1.224 (±1.779) a memantina. Conclusiones: Una tercera parte de los pacientes con demencia tuvieron prescritos antipsicóticos, mayoritariamente atípicos, más frecuentemente en los mayores de 85 años y durante periodos prolongados. La prescripción de IACE y memantina se asoció al incremento del riesgo de uso de antipsicóticos, pero paradójicamente, a la prolongación del tiempo hasta su prescripción.(AU)

ObjectiveWe have analyzed the prevalence of antipsychotics in patients with dementia in Spain, their age distribution and the influence of treatment with IACEs and memantine on their prescription. Method: Descriptive, retrospective and cross-sectional study of the 2017 BIFAP database in over 65 years of age with dementia. Prescriptions of antipsychotics, IACEs and memantine were collected. For antipsychotics were also collected, the duration of treatment and time from dementia diagnosis to prescription. Results: A total of 1,327,792 subjects were retrieved, 89,464 (6.73%) with dementia. Antipsychotics were prescribed in 31.76%; by frequency: quetiapine (58.47%), risperidone (21%) and haloperidol (19.34%). Prescriptions of IACEs and memantine were clustered in those younger than 84 years and antipsychotics in those older than 85 (P<.001). Antipsychotics were maintained for a mean of 1174.5 days. In 26.4% of cases they were prescribed alone, OR 0.61 (95% CI: 0.59-0.62), in 35.85% associated with IACEs, OR 1.26 (95% CI: 1.22-1.30) and in 42.4% with memantine, OR 1.69 (95% CI: 1.62-1.78) (P<.000). From the diagnosis of dementia, 461 days (±1576.5) elapsed when isolated drugs were prescribed; 651 days (±1574.25) associated with IACEs and 1224 (±1779) with memantine. Conclusions: One third of patients with dementia were prescribed antipsychotics, mostly atypical, more frequently in those older than 85 years and for prolonged periods. IACEs and memantine were associated with the risk of antipsychotic prescription, but paradoxically, with prolonged time to onset.(AU)
