Examining the “Potentially Preventable Emergency Department Transfer” Indicator Among Nursing Home Residents

Published:November 12, 2022DOI:https://doi.org/10.1016/j.jamda.2022.10.006

      Abstract

      Objective

      To determine if nursing home (NH) resident characteristics associated with potentially preventable emergency department transfers (PPEDs) are similarly associated with non–potentially preventable emergency department transfers (non-PPEDs).

      Design

      We conducted a population-level retrospective cohort study using linked administrative data reported using the Resident Assessment Instrument–Minimum Data Set Version 2.0 and the National Ambulatory Care Reporting System for emergency department transfers.

      Setting and Participants

      We assessed all NH residents transferred to the emergency department within 92 days after admission. The cohort included 56,433 NH resident admissions assessment of which 3498 NH residents experienced PPEDs, and 9331 residents experienced non-PPEDs.

      Methods

      We assessed Ontario NH residents admission assessments collected between January 1, 2017, and December 31, 2018. We used cumulative incidence functions and Cox regression to compare resident characteristics between residents experiencing PPEDs and non-PPEDs. PPEDs were defined based on the International Classification of Diseases, 10th Revision.

      Results

      Approximately 23% of residents experienced an emergency department transfer within 92 days of NH admission. The cumulative incidence of PPEDs was 6.3% and non-PPEDs was 16.8%. After adjusting for clinically relevant features, 14 of 18 resident admission characteristics were associated with both types of transfers. Resident admission characteristics associated with a greater risk of PPEDs solely were pneumonia [hazard ratio (HR) 1.48; CI 1.25–1.70] and oxygen therapy (HR 1.88; CI 1.69–2.10). Resident admission characteristics associated with a greater risk of non-PPEDs solely are experiencing a change in mood (HR 1.09; CI 1.01–1.18) and delirium (HR 1.08; CI 1.04–1.13).

      Conclusions and Implications

      PPEDs were associated with a similar cluster of NH resident characteristics as those transferred for non-ambulatory reasons, suggesting that the clinical distinction between PPEDs vs non-PPEDs within the NH might be unclear. These findings highlight that the PPED indicator could be revised to improve specificity.
