Do nursing homes with a higher proportion of residents with dementia have greater or fewer complaints?

Objectives: Nursing home (NH) residents' capacity to communicate deteriorates with dementia. Consequently, NHs with high proportions of people living with dementia (PLWD) may receive fewer resident complaints, and/or investigating complaints may be challenging. We assessed NHs' proportion of PLWD in relation to total and substantiated complaints.Methods: Data were from the ASPEN Complaints/Incident Tracking System and the Certification and Survey Provider Enhanced Reports (2017). NHs (N = 15,499) were categorized based on high (top-10%), medium (middle-80%), and low (bottom-10%) dementia prevalence. Negative binomial Poisson regression assessed complaint patterns in relation to NHs' high/low (vs. medium) proportions of PLWD and other facility/resident characteristics.Results: Compared to NHs with medium-dementia prevalence, NHs with low proportions of PLWD had higher total (average marginal effect [AME] = 0.16, p < 0.001) and substantiated (AME = 0.30, p < 0.001) complaints, whereas NHs with high proportions of PLWD had fewer total (AME= -0.07; p < 0.05) and substantiated (AME= -0.11, p < 0.05) complaints. Also, NHs' profit status, chain-affiliation, size, staffing, and resident ethnicity were associated with total and substantiated complaints.Conclusion: The association between high proportions of PLWD and lower NH complaints suggests either that these NHs have higher overall quality or that complaints are underreported. Regardless, surveyors and families may need more involvement in monitoring higher dementia prevalence facilities.
