Scientific Questions Being Studied
The overarching goal of this study is to improve the prediction of clinically significant adverse drug events (ADEs) by harnessing the data that is made available through the All of Us program. Although a number of ADE risk prediction tools are published in the literature, none are universally accepted and used routinely in clinical practice. Robust ADE risk prediction tools are lacking because most datasets utilized to derive ADEs are largely not generalizable. Furthermore, interindividual susceptibility to ADEs might be explainable by genetic variations, and such information is not often available in prediction models. Our specific aims are:
1. Determine the prevalence, specific types and characteristics of ADEs among participants who are receiving chronic disease medications.
2. Derive and validate a prediction model to identify characteristics that are associated with ADEs related to selected chronic disease medications.
- Disease Focused Research (Definitions, analyses and prediction of adverse drug reactions/events)
- Population Health
- Social / Behavioral
Descriptive statistics will be utilized to characterize the prevalence, specific types and characteristics of ADEs for each drug. Univariate analysis with chi-square tests will be conducted to calculate odds ratios (together with 95% confidence interval) for ADEs associated with each potential risk factor, followed by multivariate logistic regression analysis using backwards selection to identify statistically significant factors and ultimately derive an ADE prediction model for each selected drug.
Our study also intends to fill a current research gap and present findings to contribute an indispensable part of a future larger study that examines ADEs for association with both patient characteristics and pharmacogenetic information, when available, which will contribute an additional layer of information critical to the preventability of ADEs. There will be added focus on specific ethnic groups previously under-described in literature, including Hispanics and African Americans. While limitations such as inconsistency in recording of ADEs and risk factors are anticipated, an advantage of this study is that cases and controls will be selected from a large participant pool (All of Us) rather than a specific site, which will allow us to evaluate the impact of ADEs in a group that better mirrors the general patient population in the clinical setting.
