Abstract
Background: The elderly play an important role in health care. One of the biggest issues of the health care for the elderly is medical prescriptions. Some medications perform well in the general population while they would cause side effects that outweigh the benefits in the elderly, which are called potentially inappropriate medications (PIMs). PIMs were prescribed very often in the emergency department (ED), where the pace is fast and chaotic. The program “Enhancing Quality of Provider Practices for Older Adults in the Emergency Department (EQUiPPED)” was created with the hope to reduce the use of PIMs. The previous study found it effective in VA settings. We implemented EQUiPPED and analyzed its performance on reducing PIMs count/rate in the first non-VA setting in this paper.
Methods: The intervention include provider education, EHR-based clinical decision tools and provider feedback. The intervention was divided into three periods: Pre-Intervention, Post- Intervention and Intervention (five months). Both weekly- and monthly-based PIMs rates were calculated, and the changing trends were analyzed. Bonferroni adjusted proportion test and exact ratio test were conducted to find the unadjusted effect of EQUiPPED on PIMs rate. Several regression models for count outcomes were fitted and compared. A regression-based test was used to determine the adjusted effect on the final model.
Results: The EQUiPPED program successfully was implemented. The Bonferroni adjusted proportion test indicated significant differences between both Pre-Intervention vs Post-Intervention and Intervention vs Post-Intervention (P-value both < 0.001). The exact rate ratio test gave us similar outcome: with an estimated ratio of 2.51(95% confidence interval 2.30 – 2.73, P-value < 0.001). Negative binomial model was selected given the outcome of Vuong test, dispersion parameter, AIC and BIC. Two models with covariates selected using different criteria were finally fitted. The adjusted effects of EQUiPPED period showed no signs of effectiveness (P-value = 0.40 and 0.44 respectively for these two models)
