Journal ArticleDOI
Cost-effectiveness of bariatric surgical procedures for the treatment of severe obesity
Bruce C. M. Wang,Edwin S. Wong,Rafael Alfonso-Cristancho,Hao He,David R. Flum,David Arterburn,Louis P. Garrison,Sean D. Sullivan +7 more
TL;DR: This study evaluated the cost-effectiveness of common bariatric surgical procedures in the US from a healthcare system perspective and developed a two-part model using a deterministic approach for the first 5-year period post-surgery and separate empirical forecasts for the natural history of BMI, costs and outcomes in the remaining years.
Journal ArticleDOI
Comparative effectiveness of mepolizumab and omalizumab in severe asthma: An indirect treatment comparison.
Sarah Cockle,Gillian Stynes,Necdet B Gunsoy,Daniel Parks,Rafael Alfonso-Cristancho,Jaro Wex,Eric S. Bradford,Frank C. Albers,Jenny Willson +8 more
TL;DR: It was shown that in patients with severe asthma, mepolizumab seems to be at least as effective as omalizumabs and that the tolerability profiles of the two treatments did not meaningfully differentiate.
Journal ArticleDOI
Examining the BMI-mortality relationship using fractional polynomials
Edwin S. Wong,Bruce C. M. Wang,Louis P. Garrison,Rafael Alfonso-Cristancho,David R. Flum,David Arterburn,Sean D. Sullivan +6 more
TL;DR: The MFP approach provides a robust alternative to categorization or conventional linear-quadratic models for BMI, which limit the number of curve shapes, and is potentially useful in estimating the relationship between the full spectrum of BMI values and other health outcomes, or costs.
Journal ArticleDOI
A model for incorporating patient and stakeholder voices in a learning health care network: Washington State's Comparative Effectiveness Research Translation Network.
Emily Beth Devine,Rafael Alfonso-Cristancho,Allison Devlin,Todd C. Edwards,Ellen T. Farrokhi,Larry Kessler,Danielle C. Lavallee,Donald L. Patrick,Sean D. Sullivan,Peter Tarczy-Hornoch,N. David Yanez,David R. Flum +11 more
TL;DR: The CERTAIN's inaugural cohort study may serve as a useful model for conducting PCOR and creating a learning health care network and the patient centeredness of this cohort study is focused on.
Journal ArticleDOI
Implementation of a “real-world” learning health care system: Washington state's Comparative Effectiveness Research Translation Network (CERTAIN)
David R. Flum,Rafael Alfonso-Cristancho,Emily Beth Devine,Allison Devlin,Ellen T. Farrokhi,Peter Tarczy-Hornoch,Larry Kessler,Danielle C. Lavallee,Donald L. Patrick,John L. Gore,Sean D. Sullivan +10 more
TL;DR: This work has described the components of the CERTAIN infrastructure, the elements of a pilot project evaluating treatments of claudication, and the opportunities and challenges of developing and implementing a "real world" learning system.
