Background: Dementia patients frequently depend on caregivers. Agitation is a common behavioral dementia symptom particularly burdensome to patients and caregivers. Objective: To assess the association of agitation severity with non-professional caregiver hours, burden, health status, and productivity. Secondarily, to assess the association of agitation severity with these outcomes for patients receiving remote (not living with the patient) and proximate (living with the patient) caregiving. Methods: A retrospective analysis of physician and non-professional caregiver-reported data from a US point-in-time survey. Patients were aged ≥50 years, with early cognitive impairment or dementia. Regression analyses compared outcomes by agitation severity; covariates included age, sex, and clinical characteristics. Results: Data were included for 1,349 patients (non-agitated n = 656, agitated n = 693; no care n = 305, remote care n = 248, proximate care n = 691; unknown care n = 105). Greater agitation was significantly associated (p < 0.05) in all caregivers with increasing: Zarit Burden Interview (ZBI) Total Caregiver Burden, Personal Strain, Role Strain, and Guilt; Work Productivity and Activity Index (WPAI) presenteeism, overall work impairment, and total activity impairment. Higher ZBI Total Caregiver Burden, Personal Strain, and Role Strain were associated with greater agitation in proximate caregivers and higher ZBI Guilt associated with greater agitation in remote caregivers (p < 0.05). Higher WPAI presenteeism and total activity impairment were associated (p < 0.05) with greater agitation in proximate caregivers. Caregiving hours increased with increasing agitation for proximate caregiving (p = 0.001). Conclusion: Greater agitation severity was associated with higher caregiver burden and lower productivity, with higher indirect costs a likely outcome of agitation.
