Rapid growth in elderly population and higher prevalence of dementia necessitates further attention to dementia. Even though early detection and continuing care are mainstays of dementia care, limited access to dementia diagnosis and dementia care planning for elders could be attributed to factors like low dementia literacy-the capacity to obtain, process, and understand basic dementia-related information and services to make appropriate health decisions-and lack of social support. Developing innovative pathways to transition families of individuals with probable dementia into healthcare access for early diagnosis of dementia and timely dementia care planning can benefit patients and the patients' families. To this end, the investigators' study aims are to develop a home-based intervention program for dementia evaluation, education, and care planning and test its feasibility and acceptability in a pilot study.
This research is being done to understand how an education and navigation support program led by trained Nurse Practitioners (NPs) helps older adults with probable dementia and the patients' caregivers. In a 2-arm randomized controlled trial (RCT) with 40 dyads, the investigators' aims are to (1) test the effect of a community-based intervention delivered by trained NPs for undiagnosed older adults with probable dementia and the patients' caregivers, (2) evaluate the effect of the PLAN on improving caregiver's dementia literacy, self-efficacy in dementia care and service use, social support, depression, and quality of life at 6 months in comparison to a group of participants who receive a copy of the publicly available educational material, and (3) examine whether the effect of PLAN differs across age, sex, and education caregiver subgroups. Aim 1 tests the following hypotheses: older adults with probable dementia who receive the PLAN will have higher rates of linkage to medical service for dementia than those in the control group. Aim 2 tests the following hypothesis: caregivers in the PLAN group will have higher dementia literacy, self-efficacy in dementia care and service use, social support, and quality of life, and lower depression than those in the control group.

Number of participants linked to medical service for dementia
Number of participants linked to medical service for dementia measured by medical record verification. Linkage to medical service for dementia is defined as having had primary care or specialty care provider evaluation for cognitive impairment.
Time frame: 6 months
Number of participants who complete a plan for dementia care
Completion of a plan for dementia care is measured by study questionnaire: "yes" or "no".
Time frame: 6 months
Number of participants who complete advanced directives
Completion of advanced directives is measured by study questionnaire: "yes" or "no".
Time frame: 6 months
Change in functional ability for activities of daily living as assessed by Katz scores
The Katz Index of Independence in Activities of Daily Living is a 7-item instrument, with 1 point assigned for each item respondents are able to perform independently without supervision, direction, or guidance. Scores range from 0 to 6 with higher scores indicating higher independence.
Time frame: Baseline and 6 months
Change in functional ability for instrumental activities of daily living as assessed by Lawton-Brody scores
The Lawton-Brody Instrumental Activities of Daily Living Scale is an 8-domain instrument (5 domains historically used for men), with 1 point assigned for each statement that reflects higher levels of functioning. Summary scores range from 0 to 8 (5 for men) with higher scores indicating higher functioning and independence.
Time frame: Baseline and 6 months
Change in Patient quality of life as assessed by Quality of Life-Patient scores (for all patient participants)
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
QoL-dementia older adult is a 13-item instrument and scoring ranges from "poor" coded as 1 to "excellent" coded as 4 for each item. Total scores will range from 13 to 52 with higher scores indicating higher quality of life.
Time frame: Baseline and 6 months
Change in Dementia Literacy as assessed by Rapid Estimate of Adult Literacy in Medicine (REALM)-Dementia scores (for all caregiver participants)
The dementia literacy test is a 11-item instrument. Scoring of the dementia literacy instrument is in such a way that each correct response will be coded as 1 whereas incorrect response will be coded as 0. Total scores can range from 0 to 11 with higher scores indicating higher dementia literacy.
Time frame: Baseline and 6 months
Change in Social Support as assessed by Medical Outcomes Study (MOS)-Social Support survey scores (for all caregiver participants)
The 8-item scale of medical outcomes study scoring ranges from "none of the time" coded as 1 to "all of the time" coded as 5 for each item. Total scores will range from 8 to 40 with higher scores indicating higher social support.
Time frame: Baseline and 6 months
Change in depression as assessed by Patient Health Questionnaire-2 (for all caregiver participants)
Patient health questionnaire-2 is a 2-item instrument and scoring ranges from "not at all" coded as 0 to "nearly every day" coded as 3. Total scores will range from 0 to 6 with higher score indicating greater depressive symptoms.
Time frame: Baseline and 6 months
Change in self-efficacy as assessed by Self-Efficacy Dementia Scale scores
Dementia self-efficacy scale is a 10-item instrument. Scoring of the dementia self-efficacy scale ranges from "not at all certain" coded as 1 to "very certain" coded as 10 for each item. Total scores will range from 10 to 100 with higher scores indicating higher self-efficacy.
Time frame: Baseline and 6 months
Change in Caregiver Quality of Life
QoL-dementia caregiver is a 13-item instrument and scoring ranges from "poor" coded as 1 to "excellent" coded as 4 for each item. Total scores will range from 13 to 52 with higher scores indicating higher quality of life.
Time frame: Baseline and 6 months
Program satisfaction as assessed by study questionnaire
Caregiver satisfaction with the intervention program will be measured on a 10-point visual analogue scale, with scoring ranges from 0 "not at all satisfied" to 10 "extremely/highly satisfied". Higher scores will indicate greater satisfaction with program.
Time frame: 6 months
