Adjustments for unmeasured confounders in pharmacoepidemiologic database studies using external information.
BACKGROUND Nonexperimental studies of drug effects in large automated databases can provide timely assessment of real-life drug use, but are prone to confounding by variables that are not contained in these databases and thus cannot be controlled. OBJECTIVES To describe how information on additional confounders from validation studies can help address the problem of unmeasured confounding in ...
متن کاملSensitivity analysis and external adjustment for unmeasured confounders in epidemiologic database studies of therapeutics.
BACKGROUND Large health care utilization databases are frequently used to analyze unintended effects of prescription drugs and biologics. Confounders that require detailed information on clinical parameters, lifestyle, or over-the-counter medications are often not measured in such datasets, causing residual confounding bias. OBJECTIVE This paper provides a systematic approach to sensitivity a...
متن کاملMeta-analysis of observational studies with unmeasured confounders.
Meta-analysis of observational studies is an exciting new area of innovation in statistical science. Unlike randomized controlled trials, which are the gold standard for proving causation, observational studies are prone to biases including confounding. In this article, we describe a novel Bayesian procedure to control for a confounder that is missing across the sequence of studies in a meta-...
متن کاملSensitivity analysis for unmeasured confounders using an electronic spreadsheet.
In studies assessing the effects of a given exposure variable and a specific outcome of interest, confusion may arise from the mistaken impression that the exposure variable is producing the outcome of interest, when in fact the observed effect is due to an existing confounder. However, quantitative techniques are rarely used to determine the potential influence of unmeasured confounders. Sensi...
متن کاملValidity of perinatal pharmacoepidemiologic studies using data from the RAMQ administrative database.
BACKGROUND The RAMQ prescription claims database (RAMQ-Rx) is increasingly being used in perinatal pharmacoepidemiologic studies; but, there are reasons to believe that results generated with the RAMQ-Rx might not be generalizable to all patient populations. OBJECTIVES Compare characteristics between pregnant women insured by the RAMQ-Rx and those insured by a private drug insurance plan. M...
