Oral Hygiene in Assisted Living

Aging, Long-Term Care

Mouth Care

This project will modify a program that reduces pneumonia among nursing home residents with dementia, so that it is appropriate for assisted living residents with dementia. The program provides daily mouth care to reduce bacteria in the mouth that lead to aspiration pneumonia. The project will develop methods that can be taught to assisted living providers by community dental hygienists, and that are ready for evaluation in a pragmatic trial of AL residents with dementia and the staff who provide their care.

It could be said that many dementia care and caregiver support interventions are too limited, focusing solely on psychosocial and behavioral concerns. These issues are important, but so too is the physical health of people with dementia -- especially because they are living longer and require more support with health care and activities of daily living. Just imagine the benefit of a physical health care intervention provided daily. Case in point: tooth brushing, flossing, and gum and denture care. Many people with dementia resist mouth care - almost 90% in nursing homes, in fact. As a result, only 16% have their teeth brushed regularly, putting them at risk for aspiration pneumonia when they inhale bacteria from their teeth, tongue, and gums. In 2013, the research team submitting this proposal developed one of the two existing dementia-focused mouth care programs for nursing homes -- Mouth Care Without a Battle (MCWB) -- which already has become a standard of nursing home care. MCWB changes caregivers' attitudes and behavior, improves oral health, and in a cluster randomized trial, MCWB provided by nursing assistants reduced pneumonia incidence by 32 percent. The next frontier is to extend MCWB to assisted living (AL), the primary long-term residential care provider for persons with dementia. There are 30,200 AL communities across the country; 90% of their 835,200 residents have cognitive impairment and 42% have moderate or severe dementia (and on average, five untreated oral health conditions), meaning MCWB has the potential to improve the health and quality of life of more than 350,000 AL residents with dementia annually. There is a unique and timely opportunity to transform MCWB so it is optimally suitable for AL, given the North Carolina Department of Health and Human Services (DHHS) Special Care Dentistry Program offer of partnership. Consequently, the investigators propose this nested cohort cluster randomized trial that will apply the NIH Stage Model and principles of the Science of Behavior Change (SOBC) to lay the groundwork for a pragmatic trial and real-world implementation of MCWB for AL residents with dementia and their caregivers. The aims of the proposed project are to refine MCWB (NIH Stage I/Aim 1), and examine research efficacy (NIH Stage II/Aim 2) and real-world efficacy (NIH Stage III/Aim 3), focusing on structural, social, and interpersonal mechanisms as the SOBC target. Aims 2 and 3 will use separate samples of AL communities (24 for Aim 2 and 28 for Aim 3) across the state's ten regions. Within each region, one-half of AL communities will be randomized to treatment (MCWB) and one-half to control, and the oral hygiene of up to 360 residents with dementia will be assessed through eight months. For Aim 3 there will be up to 233 residents assessed for four months. In Aim 2, a research dental hygienist will train AL staff on MCWB and provide ongoing support; in Aim 3, this responsibility will be transferred to community public health dental hygienists working with the DHHS. Family members (one per resident, up to 360 for Aim 2 and up to 233 for Aim 3) will also be interviewed about the resident. Assisted Living staff will also be interviewed at each baseline and follow-up visit (up to 360 for Aim 2 and up to 360 for Aim 3). Aim 1. Refine MCWB for implementation in assisted living (AL) communities. 1. Identify stakeholder perspectives. Interview (1) the administrator, health care supervisor, and a personal care aide (PCA) from 20 AL communities across North Carolina who have already been trained in MCWB by community-based public health dental hygienists from the DHHS Special Care Dentistry Program, and (2) the dental hygienists who provided that training, to learn attitudes regarding MCWB as developed for nursing homes, the extent to which care has changed, and recommended modifications to MCWB for AL. 2. Create a one-hour MCWB training video (web and digital versatile disc format) targeted to AL. Modifications include videorecording AL staff providing mouth care to residents with dementia, and interviews with residents and families; AL administrators, supervisors and PCAs; and dental hygienists. Aim 2. Evaluate research efficacy of the MCWB program, with training and support provided by an experienced research dental hygienist. 1. Evaluate MCWB in terms of (1) the reach of the intervention; (2) effects on mediators/targets of change at the organizational and individual level; (3) resident outcomes (oral hygiene, pneumonia, hospitalizations); (4) associations between change at the organizational and individual level and outcomes, and also associations with characteristics of the AL community and staff; and (5) attitudes, barriers, and facilitators. 2. Develop a coaching manual for community hygienists to provide training and support to AL staff, reflecting lessons-learned from analyses. Aim 3. Evaluate real-world efficacy of the MCWB program, transferring responsibility for training and support to community public health dental hygienists, thereby testing efficacy of a nationally generalizable model. 1. Assess dental hygienists' (up to N=24) self-efficacy to provide training and support at baseline and 4 months. 2. Evaluate MCWB as per Aim 2a, including examining associations with characteristics of the hygienists. 3. Compare implementation and effectiveness outcomes between research and real-world efficacy. 4. Refine the coaching manual for community dental hygienists to provide training and coaching, reflecting lessons-learned from analyses. By the conclusion of this project, MCWB will be ready for evaluation in a pragmatic trial of AL residents with dementia and the staff who provide their care. Note that the CT.gov record includes only the assisted living residents enrolled in the clinical trial, not secondary participants (staff, hygienists).
