OBJECTIVES: To describe acetylcholinesterase inhibitor (AChEI) and memantine use among persons over the age of 65 admitted to hospice with a primary diagnosis of dementia and identify patient and hospice program characteristics associated with the use of these agents. DESIGN: Retrospective, cross-sectional study. SETTING: Administrative database of a national hospice pharmacy provider. PARTICIPANTS: A total of 10,065 persons with end-stage dementia admitted to one of 441 U.S. hospices in 2004. MEASUREMENTS: The frequency of AChEI and memantine use was determined and utilized as the unit of analysis for bivariate and multivariate comparisons with patient and hospice program characteristics. RESULTS: Twenty-one percent (2148/10,065) of patients were prescribed AChEI and/or memantine therapy at the time of hospice enrollment. Of these, 49.5% were prescribed donepezil. Odds of receiving AChEI and/or memantine therapy were less likely if the patient was female, (odds ratio [OR] 0.68, 0.62-0.76), died while enrolled in hospice (OR 0.75, 0.67-0.85), received care at home (0.80, 0.71-0.89), or had a hospice length of stay (LOS) less than 7 days (0.53, 0.45-0.62). Patients who had a LOS of at least 60 days were significantly more likely to have received such therapies (OR 1.41 [1.24-1.60] for 61-180 days and 1.33 [1.15-1.54] for over 180 days). CONCLUSION: A notable number of hospice enrollees with a primary diagnosis of dementia were prescribed AChEI and/or NMDA receptor antagonist therapy. Studies are needed to better define the role of these agents as well as the impact of medication discontinuation in persons with end-stage dementia.
