This study aimed to evaluate the effect of psychoeducational intervention (PI) on donepezil retention rates and identify the factors associated with donepezil continuation in patients with AD.Patients and Methods: One hundred and seventeen patients with AD were randomly allocated to the PI (n = 58) or standard care (SC; n = 59) groups. All patients were prescribed donepezil for 48 weeks. Primary endpoints were the 48-week donepezil retention rate and the reasons for donepezil discontinuation in the PI and SC groups. The secondary endpoint was the predictive factors, among the baseline clinical variables, for donepezil continuation in all patients.Results: The donepezil retention rate was 62.1% (36/58) in the PI group and 66.1% (39/59) in the SC group. The most common reason for discontinuation in both groups was adverse events (PI, 12.1%; SC, 10.2%). Logistic regression analysis revealed that the results of the pentagon copying test in the Mini-Mental State Examination administered at baseline was a significant predictor of donepezil continuation for all patients in both the groups (odds ratio: 0.359; 95% confidence interval: 0.154– 0.839).Conclusion: There was no significant difference between the PI and SC groups concerning donepezil retention rate in patients with AD. Our results demonstrate that the pentagon copying test can significantly predict donepezil continuation in patients with AD, indicating that impaired visuospatial and executive functions may reflect medication discontinuation.Trial Registration: UMIN-CTR:UMIN000012617.Keywords: adherence, cholinesterase inhibitors, medication discontinuation, Mini-Mental State Examination, pentagon copying task |
