No prior experience with target trials, pharmacoepidemiology, or clinical epidemiology required.

Facilitators: Barbra Dickerman, Lucia Petito, & Kerollos Wanis

Heard about causal graphs or DAGs and curious to know more? Join us for a collaborative, hands-on exercise in building causal graphs! Using an example from psychiatric epidemiology, this workshop will provide a practical tutorial on summarizing expert knowledge into a causal graph and using that graph to think about study design and analyses. No prior experience with causal graphs or psychiatric epidemiology required.

Facilitators: Eleanor Murray, Jaimie Gradus, & Matthew Fox

Presenters: Louisa Hills Smith & Laura Ann Sampson

Workshop: Causal Survival Analysis in Follow-Up Studies

Friday November 2, 2018 | 3:45-5:30pm | Ballard Room, Countway Library

Do you work with survival data? Are you wary of the hazards of hazard ratios? Learn how to estimate survival outcomes adjusted for baseline and time-varying confounders! This practical, hands-on workshop will cover estimating survival curves, cumulative incidence differences & ratios, and inverse probability-weighted hazard ratios for intention-to-treat effects and per-protocol treatment effects for randomized trials and observational data.   Bring a laptop with R or SAS, we’ll provide the code and real data!

Facilitated by Lucia Petito & Eleanor Murray

Should Women Use Acetaminophen during Pregnancy? A discussion of analytic choices and improbable study findings.

Friday October 5, 2018 | 3:45-5:30pm | Ballard Room, Countway Library

Currently, acetaminophen is the only over-the-counter pharmaceutical drug approved by the Food and Drug Administration (FDA) for women to use during pregnancy for pain relief or fever reduction. However, recent studies done in cohorts around the world have found an increased risk of neurocognitive outcomes (e.g. ADHD diagnosis, slower language development, lower IQ) in children of women who used acetaminophen during pregnancy. In 2014, the FDA reviewed this research and deemed the level of evidence not high enough to change the current recommendation. In this symposium, we will discuss possible sources of bias in these analyses of cohort data that may have influenced study findings (unmeasured confounding, measurement error, selection bias), what the regulatory implications of these findings are, and how to proceed when study findings polarize the scientific community.

The Data Science of Implementation Science

Friday, May 4, 2018 | 3:45-5:30pm | Ballard Room, Countway Library

Implementation science aims to study the process by which original research becomes widely disseminated. It has been described as “a systematic, scientific approach to ask and answer questions about how to get ‘what works’ to people who need it with greater speed, fidelity, efficiency, quality, and relevant coverage.” However, there are many analytic challenges to consider when assessing the effectiveness of the implementation of a public health intervention, which may, at many stages, not be what the original research recommended. In this symposium, we will 1) describe the basic principles of implementation science, 2) provide a concrete example of the public health significance of an implementation science study, and 3) demonstrate some of the methodological work underway to address such challenges.

Did your mother’s prenatal diet affect you? Using lifecourse data to answer intergenerational questions

Friday, April 6, 2018 | 3:45-5:30pm | Ballard Room, Countway Library

Co-hosted by the Division of Chronic Disease Research Across the Lifecourse (CoRAL) and the Program on Causal Inference

Many chronic childhood diseases are thought to originate in the early stages of human development. Prenatal diet is thought to be a modifiable risk factor that directly impacts child growth in utero. In this symposium, we plan to discuss 1) the evidence that supports the effect of prenatal diet on offspring childhood health outcomes, 2) how researchers use complex longitudinal surveys to conduct intergenerational research, and 3) how to incorporate causal inference ideas into future analyses.

Evidence-Based Policy: How can we use health data to build better microsimulation models?

Friday, March 2, 2018 | 3:45-5:30pm | Ballard Room, Countway Library

Co-hosted by the Center for Health Decision Science and the Program on Causal Inference

Many health policy questions cannot be answered by conducting randomized trials or analyzing observational data. To address these questions, researchers have turned to microsimulation models, which incorporate data from varying sources. In this symposium, we aim to better understand: 1) the types of questions microsimulation models are used to answer, 2) the evidence used to create an individual-level microsimulation model, and 3) the connections between microsimulation models and the parametric g-formula, a causal inference technique. We will discuss recommendations for practical implementation of both methodologies.

Do statins increase the survival of cancer patients?

Friday, February 2, 2018 | 3:45-5:30pm | Ballard Room, Countway Library

Co-hosted by the Program on Causal Inference, the Cancer Epidemiology Program, and the Harvard Chan Student Club on CANcer: Learn, Interact, Translate (CAN-LIT)

Over 25 million Americans take statins. While the cardiovascular benefits of statins are not under discussion, there is a debate as to whether statins increase the overall survival of cancer patients. This protective effect is biologically plausible and, in fact, reports from several observational studies have found an inverse association between statins and mortality among cancers patients. However, some of these studies did not explicitly emulate a randomized trial, which might have introduced selection bias and immortal time bias in the estimates. So do statins increase survival in cancer patients or is the inverse association due to bias? In this symposium we will address this question by discussing the available evidence on statins and mortality in cancer patients and will chart a research path forward.
