Ben was a Post-doctoral Research Fellow in decision science at Massachusetts General Hospital's Institute for Technology Assessment. He also completed a Master's degree in Public Health at the Harvard T.H. Chan School of Public Health (concentration: health policy and management).
Ben is a health services researcher, decision-analytic modeler, and health economist; he serves as a co-editor of a peer-reviewed journal in those fields, Value in Health. His research had applications across medical conditions although most were in cardiovascular disease. Ben has served as a consultant on cost-effectiveness analysis and reimbursement for medical device and biotech companies. He regularly contributes peer reviews to several scientific journals. Ben also enjoys teaching as well as running quality improvement/patient safety (QI/PS) projects. Recently, Ben has become interested in "big data" and how to use routinely collected health information for research and QI/PS.
Ben's ultimate career goal is to be an active citizen in the academic hospital medicine community.
Previous research projects
Previous research projects included:
Cost-effectiveness of Renal Denervation for Resistant Hypertension
The purpose of this study was to assess cost-effectiveness and long-term clinical benefits of renal denervation in resistant hypertensive patients. A probabilistic state-transition (Markov) model with multivariate risk equations for stroke, myocardial infarction, all coronary heart disease, heart failure, and end-stage renal disease was used to project clinical endpoints, survival, costs, quality-adjusted life-years, and incremental cost-effectiveness analysis.

Budget Impact Analysis of Various Percutaneous Treatments of Femopopliteal Disease
In this project, we used pooled indirect-treatment comparison from a systematic literature search to project costs for drug-coated balloons and other transluminal interventions for peripheral artery disease.

Health Care Policy Research in the National Hospital Ambulatory Medical Care Survey

B.P. Geisler et al. PLoS One. 2010 Feb 17;5(2):e9274. doi: 10.1371/journal.pone.0009274
we combined complex survey analysis techniques combined with linear, logistic, and ordinal regression to look at the use of observational care and of electronic health record systems in emergency departments across the United States.
Comparative Effectiveness Research in Chronic Heart Failure and Methods
In a research group with A. Göhler, U. Siebert and others we worked on several projects related to economic and clinical decision analyses of interventions for chronic congestive heart failure. This included projects on erythropoiesis-stimulating agents, (disease) management programs, health-related quality of life (utility) estimates of heart failure classes, and an overview over the decision-analytic literature in this field.
We have also contributed methodological paper on deterministic sensitivity analysis for first-order Monte Carlo simulations.
UpToDate Card on Psychogenic Purpura
Since 2007 I am the author on an UpToDate card on this hematologic-psychiatric condition. We conduct regular systematic literature searches for this review article.
