A distributed health data network is a system that allows secure remote analysis of separate sets, each comprising different medical organization's or plan's records. Distributed networks are currently being planned could cover millions people, permitting studies comparative clinical effectiveness, best practices, diffusion technologies, and quality care. These also support assessment product safety other public needs. technologies allow holders to control all uses their data, which...

Abstract The US Food and Drug Administration (FDA) Sentinel System uses a distributed data network, common model, curated real-world data, analytic tools to generate evidence for FDA decision-making. system needs include flexibility, transparency, reproducibility while protecting patient privacy. Based on over decade of experience, critical limitation is the inability identify enough medical conditions interest in observational satisfactory level accuracy. Improving system’s ability use...

The self-controlled tree-temporal scan statistic-a new signal-detection method-can evaluate whether any of a wide variety health outcomes are temporally associated with receipt specific vaccine, while adjusting for multiple testing. Neither nor postvaccination potential periods increased risk need be prespecified.

Human immunodeficiency virus (HIV) pre‐exposure prophylaxis (PrEP) protects high risk patients from becoming infected with HIV. Clinicians need help to identify candidates for PrEP based on information routinely collected in electronic health records (EHRs). The greatest statistical challenge developing a prediction model is that acquisition extremely rare.
