摘要

Purpose

To document use and impact of potentially inappropriate medications on two-year progression of dementia in individuals with cognitive declines.

Methods

A retrospective study of 397 patients with Mild Cognitive Impairment (MCI) or dementia diagnosed and followed-up in outpatient memory clinics in Norway during 2009 − 18. Beers (2019)- and STOPP-2 criteria were used to identify Potentially Inappropriate Medications (PIMcogs) in individuals with cognitive impairments at baseline and two-year-follow-up. PIMcog use in terms of dementia severity, cognitive function, and neuropsychiatric and depressive symptoms were analyzed in regression models.

Results

The prevalence of PIMcogs increased from 16% at baseline to 23% at follow-up. PIMcog users were more likely to be women (63.5%), and they used more drugs, with a median of 5 drugs at baseline and 4 drugs at follow-up, compared to non-users who had a median of 3 used drugs at both time points. PIMcog users had higher median Neuropsychiatric Inventory severity sum scores (6 [3.0–11.0] versus 4.0 [2.0–7.0]) and median Cornell Scale for Depression in Dementia scores (6.5 [3.0–11.0] versus 4.0 [1.0–7.0]) compared to non-users at follow-up (p ≤ 0.002). PIMcog users exhibited more severe dementia, with a Clinical Dementia Rate-Sum of Boxes (CDR-SB) score of 7.0 (4.0–13.0) compared to 6.0 (3.5–10.0) in non-users. The median annual increase in CDR-SB was one unit, and PIMcog use at follow-up was significantly associated with more rapid progression of dementia severity.

Conclusion

Faster dementia progression was documented among PIMcog users although, the prevalence of PIMcogs was generally low in Norwegian memory clinic patients with cognitive impairments.
