Objectives
To identify and describe potentially preventable emergency department (ED) visits by nursing home (NH) residents in the United States. These visits are important because they are common, frequently lead to hospitalization, and can be associated with significant cost to the patient and the health care system.
Design
Retrospective analysis of the 2005-2010 National Hospital Ambulatory Care Survey (NHAMCS), comparing ED visits by nursing home residents that did not lead to hospital admission (potentially preventable) to those that led to admission (less likely preventable).
Setting
Nationally representative sample of United States EDs; Federal hospitals and hospitals with less than six beds were excluded.
Participants
Older (age ≥65 years) nursing home residents with an ED visit during this time period.
Measurements
Patient demographics, ED visit information including testing performed, interventions (both procedures and medications) provided, and diagnoses treated.
Results
Older NH residents accounted for 3,857 of 208,956 ED visits during the time period of interest (1.8%). When weighted to be nationally representative, these represent 13.97 million ED visits, equivalent to 1.8 ED visits annually per NH resident in the United States. More than half of visits (53.5%) did not lead to hospital admission; of those discharged from the ED, 62.8% had normal vital signs on presentation and 18.9% did not have any diagnostic testing prior to ED discharge. Injuries were 1.78 times more likely to be discharged than admitted (44.8% versus 25.3%, respectively, p<0.001), while infections were 2.06 times as likely to be admitted as discharged (22.9% versus 11.1%, respectively). CT scans were performed in 25.4% and 30.1% of older NH residents who were discharged from the ED and admitted to the hospital, respectively, and more than 70% of these were CTs of the head. NH residents received centrally acting, sedating medications prior to ED discharge in 9.4% of visits.
Conclusion
This nationally representative sample of older nursing home residents suggests ED visits for injury, those that are associated with normal triage vital signs, and those that are not associated with any diagnostic testing are potentially preventable. Those discharged from the ED often undergo important testing and receive medications that may alter their physical exam on return to the nursing facility, highlighting the need for seamless communication of the ED course to nursing homes.
