Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in quality of life, as measured by the Quality of Life in Alzheimer's disease (QOL-AD)
Time Frame: every 2 weeks for up to one year
Measured using the self-reported QOL-AD questionnaire comprised of 13 questions with a scale of poor = 1, fair = 2, good = 3, excellent =4. Scores range from 13 to 52, with higher scored indicating better quality of life.
every 2 weeks for up to one year
Change in sleep quality, as measured by the Pittsburgh Sleep Quality Index (PSQI)
Time Frame: every 2 weeks for up to one year
Measured using the self-reported PSQI that uses 9 questions regarding sleep quality to determine a final score where a total of "5" or greater is indicative of poor sleep quality.
every 2 weeks for up to one year
Change in dementia related behaviors and delirium, as measured by the Neuropsychiatric Inventory-Questionnaire (NPI-Q)
Time Frame: every 2 weeks for up to one year
Measured using the self-reported NPI-Q questionnaire that reports Yes = present or No = absent on 12 domains. If yes, then the informant rates the severity of the symptoms on a 3-point scale (1 = mild, 2 = moderate, 3 = severe) and the distress of the symptoms on a 5-point scale (0 = not distressing at all, 1 = minimal, 2 = mild, 3 = moderate, 4 = severe, 5 = extreme or very severe).
every 2 weeks for up to one year
Change in mood, as measured by the Patient Health Questionnaire 9 (PHQ-9)
Time Frame: every 2 weeks for up to one year
Measured using the self-reported PHQ-9 questionnaire that uses 9 question regarding patient health with a sale of not at all = 0, several days = 1, more than half the days = 2, nearly everyday =3. Scores range from 0 to 27, with higher scored indicating grater severity of depression.
every 2 weeks for up to one year
Change in function and independence, as measured by the Katz Index of Independence in Activities of Daily living (KATZ)
Time Frame: every 2 weeks for up to one year
Measured using the self-reported KATZ questionnaire with a scale of independence = 1 and dependence = 0 to determine total score. The KATZ ranges from 0 to 6 with the lower score indicated patient is very dependent and the higher score indicated patient is independent.
every 2 weeks for up to one year
Change in medication use
Time Frame: every 2 weeks for up to one year
Measured using recorded medication use from patient's chart.
every 2 weeks for up to one year
Change in falls
Time Frame: monthly for up to one year
Measured using recorded fall data from patient's chart.
monthly for up to one year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in caregiver burden, as measured by the Caregiver Strain Index (CSI)
Time Frame: 6 months
Measured using the self-reported CSI questionnaire with a scale of Yes=1 and No=0. Total score of 7 or higher indicates a high level of stress.
6 months
