Decrease of Anticholinergic Drug Use in Nursing Home Residents in the United States, 2009 to 2017.

ABSTRACT:

Objective

To investigate the time course of anticholinergic drug use in nursing home residents and assess if any temporal change in anticholinergic use varied by nursing home quality rating.

Design

Retrospective repeated cross-sectional analysis of Medicare enrollment, Parts A, B, and D, claims data linked to the Minimum Data Set from 2009 to 2017.

Setting

Medicare-certified nursing homes.

Participants

Long-term residents 65 years or older with nursing home stay of at least 100 consecutive days within a given calendar year.

Measurements

Estimates of anticholinergic drug prescription rates between 2009 and 2017 were based on a binary variable indicating whether a resident received a drug with high anticholinergic activity, as defined by the Anticholinergic Cognitive Burden scale, for at least 1 day during the initial 100 consecutive days of nursing home stay in a given calendar year. We used mixed effects logistic regression models to determine adjusted rates of anticholinergic use each year and test the interaction between nursing home quality rating and year, while adjusting for patient and nursing home characteristics.

Results

The cohort included 786,858 100-day nursing home stays (299,354 unique residents) in 6,703 nursing homes for the years 2009 to 2017. Prescription rates were stable at approximately 34% to 35% between 2009 and 2011, then gradually decreased to 24.3% in 2017 (P < .0001), with the decline being more pronounced in nursing homes having high quality ratings (P < .0001). Rates for anticholinergic drugs in nursing homes with 4 to 5 star quality rating (33.7% in 2011 to 23.3% in 2017) showed a steeper decline over time relative to nursing homes with 1 to 2 star quality rating (34.2% in 2011 to 25.2% in 2017) (P < .0001).

Conclusions

The use of drugs with high anticholinergic activity has declined from 2009 to 2017, with a greater decline in higher-quality nursing homes.

Project description:BackgroundLow nursing home staffing in the United States is a growing safety concern. Socioeconomic deprivation in the local areas surrounding a nursing home may be a barrier to improving staffing rates but has been poorly studied. Thus, the objective of this paper was to assess the relationship between neighborhood deprivation and nursing home staffing in the United States.MethodsThis cross-sectional study used 2018 daily payroll-based staffing records and address data for 12,609 nursing homes in the United States linked with resident assessment data. Our primary exposure of interest was severe economic deprivation at the census block group (neighborhood) level, defined as an area deprivation index score ≥85/100. The primary outcome was hours worked per resident-day among nursing home employees providing direct resident care. Marginal linear regression models and generalized estimating equations with robust sandwich-type standard errors were used to estimate associations between severe neighborhood deprivation and staffing rates.ResultsCompared to less deprived neighborhoods, unadjusted staffing rates in facilities located within severely deprived neighborhoods were 38% lower for physical and occupational therapists, 30% lower for registered nurses (RNs), and 5% lower for certified nursing assistants. No disparities in licensed practical nurse (LPN) staffing were observed. In models with state-level and rurality fixed effects and clustered on the county, a similar pattern of disparities was observed. Specifically, RN staffing per 100 resident-days was significantly lower in facilities located within severely deprived neighborhoods as compared to those in less deprived areas (mean difference: 5.6 fewer hours, 95% confidence interval [CI] 4.2-6.9). Disparities of lower magnitude were observed for other clinical disciplines except for LPNs.ConclusionsSignificant staffing disparities were observed within facilities located in severely deprived neighborhoods. Targeted interventions, including workforce recruitment and retention efforts, may be needed to improve staffing levels for nursing homes in deprived neighborhoods.
