Feasibility of a Systems Approach for Alzheimer's Services Among Latinos Attending Primary Care Practices

Feasibility of a Novel Systems Approach for Improving Utilization of Alzheimer's Disease Services Among Latinos Attending Primary Care Practices

The research team will train primary care practitioners from Kansas City clinics to enhance skills in cultural competence, dementia detection, treatment and referral to a Health Navigator among Latinos 65 and older with dementia. The Health Navigator will provide patient/caregiver dyads referred by Alianza Latina providers with care management, psychosocial support and links to relevant community resources. Outcomes include feasibility and acceptability of 1) PCP training and 2) patient and caregiver dementia care.

Detailed Description

Alzheimer's disease and related dementias (ADRD) are a major cause of mortality and disability in later life and cost the US healthcare system more than cancer or heart disease. The National Alzheimer's Plan Act and the National Institutes of Health have identified ADRD disparities among ethnic minorities as a public health priority. Latinos with ADRD experience substantial disparities with reduced rates of early diagnosis and lower quality care compared to their non-Latino white peers, which put them at an increased risk for steeper cognitive decline, morbidity, mortality and higher caregiver burden. A number of barriers conspire to create these disparities including a lack of an evidence-based strategy to address ADRD in clinics, patient and primary care provider (PCP) reduced ADRD knowledge, negative attitudes regarding ADRD, PCP's lack of time, cultural and language barriers and health insurance status. To improve healthcare delivery to Latinos with ADRD, researchers need to redesign current ADRD detection and care systems to follow evidence-based recommendations for early detection and culturally appropriate chronic care.

The overall aim of this proposal is to enhance the delivery of ADRD services to Latinos in primary care through a scalable systems approach that includes evidence-based recommendations. Primary care clinics are the ideal setting to provide ADRD services, as 93% of older Latinos have a usual source of healthcare. The novel systems approach (Alianza Latina/Latino Alliance) will enhance timely ADRD diagnosis and optimal care to minimize behavioral symptoms and cognitive decline among Latinos in a linguistically and culturally-appropriate way. Alianza Latina will use the Collaborative Care Framework that capitalizes on PCPs and Health Navigators. 1) PCPs will undergo evidence-based training to enhance timely and culturally appropriate diagnosis and implement it in their work routine. 2) PCPs will detect, treat and refer Latino ADRD patients to a bilingual Health Navigator to provide chronic care management, which will reduce PCP time burden.

Aim 2: Test the feasibility and acceptability of Alianza Latina. Aim 2.a: The research team will train PCPs from Kansas City clinics to enhance skills in cultural competence, ADRD detection, treatment and referral to a Health Navigator among Latinos 65 and older with ADRD. Aim 2.b. The Health Navigator will provide patients/caregiver dyads referred by Alianza Latina PCPs with care management, psychosocial support and links to relevant community resources. The research team will assess the feasibility and acceptability of 1) PCP training and 2) patient and caregiver ADRD care. Caregivers will be enrolled in a text messaging program, called CuidaTEXT, that will educate about memory and thinking problems, solve problems that are common among families with memory and thinking problems, send reminders for appointments and medications, and improve communication with the PCP, family, friends, and other resources.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Patients' Behavioral Symptoms	Brief version of the Neuropsychiatry Inventory Questionnaire: This is a validated clinical instrument for evaluating psychopathology in dementia. If any of the 12 neuropsychiatric symptoms is present, caregivers rate their loved one's severity on a three-point scale (mild-severe). For example, if the caregiver responds yes to "is the patient resistive to help from others at times, or hard to handle?", the following question would follow: "rate the severity of the symptom". An overall severity summary score is calculated by adding the severity scores of all items, ranging from 0 to 36, and higher scores mean higher severity.	Baseline and 6 months from baseline
Patients' Depression	Short Geriatric Depression Scale: This scale measures depressive symptomatology, and consists of 15 yes vs no questions. Of the 15 items, 10 indicate the presence of depression when answered positively, while the rest (question numbers 1, 5, 7, 11, 13) indicate depression when answered negatively. A summary score is obtained ranging from 0 to 15, with higher scores meaning more severe depressive symptomatology.	Baseline and 6 months from baseline
Patients' Quality of Life	Quality of Life in Alzheimer's Disease: The Quality of Life in Alzheimer's Disease is comprised of 13 items (physical health, energy, mood, living situation, memory, family, marriage, friends, self as a whole, ability to do chores, ability to do things for fun, money and life as a whole). Response options include 1(poor), 2(fair), 3(good) and 4 (excellent), for a total score of 13-52, with higher scores indicating better quality of life.	Baseline and 6 months from baseline
Caregivers' Quality of Life	In general, how satisfied are you with your life?" with a 4-point scale from 1 (Very Satisfied) to 4 (Very Dissatisfied)	Baseline and 6 months from baseline
Caregivers' Depression	10-item Center for Epidemiologic Studies-Depression scale (CES-D-10): This is a 10-item, self-report rating scale that measures characteristic symptoms of depression in the past week (e.g. depression, loneliness, restless sleep). Each item is rated on a 4-point scale, from 0 (rarely or none of the time) to 3 (most or all of the time) with positively worded items (items 5 and 8) reverse scored. Items yield summary scores that range from 0 to 30, with higher scores indicating higher severity. An example of an item is: "I was bothered by things that usually don't bother me"	Baseline and 6 months from baseline
Caregivers' Burden	Short Zarit Burden Interview: This caregiver burden scale has 6 items that address the perceived impact of the act of providing care on the physical health, emotional health, social activities and financial situation of the caregiver. Each item has five response options ranging from "never" to "nearly always". A total score is obtained by adding scores in all items, with a range from 0 to 24. Higher scores mean higher burden.	Baseline and 6 months from baseline

Plan for Individual participant data (IPD)

• Plan to Share Individual Participant Data (IPD)?: YES
• IPD Plan Description: The final dataset will include patients' and caregivers' demographic and behavioral data from interviews as well as metrics and feasibility information provided by the primary care providers. Along with the dataset, we will create a code book documenting all variables. Study participants may find their diagnosis information potentially stigmatizing, and may prefer that these diagnoses remain entirely confidential. Although the data analytic files will not have direct identifiers (only study identification numbers), the possibility of deductive disclosure of subjects with certain clinical characteristics may remain. To safeguard against the unlikely event of deductive disclosure, we will only make the data files and codebook available to other researchers on a case-by-case basis.
• IPD Sharing Time Frame: February 1, 2025
• IPD Sharing Access Criteria: Researchers requesting data will need to complete a request form outlining intended use of the data, and agree to use the data solely for this intended purpose. Prior to data release, researchers requesting data will be required to sign a confidentiality agreement specifying that they will not identify any individual participant, that they will use secure technology to safeguard the data, and that they will destroy or return the data after their analyses are completed.
