Rural-Urban Differences in Nursing Home Risk-adjusted Rates of Emergency Department Visits: A Decomposition Analysis

BACKGROUND

Higher risk-adjusted rate of emergency department (ED) visits might reflect poor quality of nursing home (NH) care; however, existing evidence is limited regarding rural-urban differences in ED rates of NHs, especially for long-stay residents.

OBJECTIVES

To determine and quantify sources of rural-urban differences in NH risk-adjusted rates of any ED visit, ED without hospitalization or observation stay (outpatient ED), and potentially avoidable ED visits (PAED) of long-stay residents.

RESEARCH DESIGN

We calculated quarterly NH risk-adjusted rates using 2011-2013 national Medicare claims and Minimum Data Set 3.0, and then implemented Generalized Estimating Equation models to examine rural-urban differences in ED rates and Blinder-Oaxaca decomposition to quantify the contributions of NH and market factors.

SUBJECTS

Privately owned, free-standing NHs in the United States (N=13,260).

RESULTS

Over the study period, risk-adjusted rates averaged 9.8% for any ED, 3.3% for outpatient ED, and 3.2% for PAED. Compared with urban NHs, rural NHs were associated with significantly lower rates of any ED, outpatient ED, and PAED (β=-1.67%, -0.44%, and -0.28%; all P<0.01). Observable differences in market factors (nursing home bed concentration, hospital beds, and the existence of a critical access hospital) explained about half of the rural-urban differences in rates of any ED and PAED, but not outpatient ED.

CONCLUSIONS

Decomposition analyses suggested that lower ED rates in rural NHs appear to be related to market availability of hospital resources. Policymakers may focus on not only reducing unnecessary ED visits but also ensuring equitable hospital access in rural areas.

Improving Quality With Emergency Department Throughput in a Critical Access Hospital

OBJECTIVE

The study objective was to determine the impact of specific measures to reduce the length of stay (LOS) in an emergency department (ED) in a critical access hospital (CAH).

BACKGROUND

Despite mandates to reduce bottlenecks by increasing throughput, many EDs are not successful. Strategies available to larger hospitals may not be feasible for resource-limited CAHs.

METHODS

Interventions were implemented to decrease ED LOS in a rural CAH. Through retrospective chart reviews from time periods both preimplementation and postimplementation, the LOS was determined and compared using 2-sample t tests.

RESULTS

Significant decreases were found between the groups in mean LOS times, as well as specific time intervals within the overall LOS time for nursing-centric activities and incidence of patients leaving prior to treatment completion.

CONCLUSIONS

A significant decrease in LOS resulted from numerous actions taken to improve patient flow. Results may be used to enhance patient flow and decrease LOS in other CAHs, improving quality and access to care.
