George Goshua, MD, MSc

Assistant Professor of Medicine (Hematology); Classical, Hematology

Research Summary

The Goshua Lab is the first research program in the United States working at the interface of quantitative decision-analytic modeling and clinical medicine, with an initial focus in classical hematology. Any clinical decision where tradeoffs exist is eligible for quantitative modeling and so we fuse state-of-the-art in quantitative decision science with clinical expertise to inform (1) guidelines, (2) health resource allocation, and (3) health policy decisions. For collaborations or to support our research, please e-mail the PI.

Extensive Research Description

As in 2017, in 2021 the United States again ranked #11/11 both on overall performance and across several domains of health care system performance in The Commonwealth Fund's reports "Mirror, Mirror 2017"and "Mirror, Mirror 2021". These rankings are despite the known, decades-long breakaway #1 global ranking in healthcare spending as percentage of GDP. Our consistent #11/11 rankings in the domains of Access (i.e., affordability and timeliness), Equity (i.e., difference between low- and high-income individuals), and Healthcare Outcomes (i.e., population health, mortality amenable to health care, disease-specific health outcomes) are particularly amenable to resource allocation optimization. That is, delivering affordable and equitable care at the right time to the right individuals. Decision analytic modeling allows an explicit quantification of effect estimates, precision intervals and uncertainty present in any given medical decision where tradeoffs are present. The United States' clinical hematologic-oncologic space is particularly rife with new, expensive therapeutic offerings, many times with unclear effect on quality-of-life, and this is where our laboratory fuses methodologic and clinical expertise.

Examples of the practical impact of recently published original science at this interface has led to 1. inpatient formulary approval of rituximab for patients with immune thrombotic thrombocytopenic purpura (TTP) in the US hospital setting, 2. inform clinical optimization of tocilizumab in a supply-limited context in Canada, 3. open international debate as to the efficacy, safety, and consequent cost-ineffectiveness of caplacizumab in immune TTP, and 4. fill an identified gap in the American Society of Hematology guidelines for optimal second-line treatment sequencing for patients with chronic immune thrombocytopenia. Ongoing and planned work includes research in allo-immunization, gene therapy, maternal-fetal hematology, complement inhibition, iron deficiency, iron chelation, thrombosis, and the quantitative modeling of health inequities in the United States.
