Doubly robust machine learning for an instrumental variable study of surgical care for cholecystitis
Kenta Takatsu, Alexander W. Levis, Edward Kennedy +2
Comparative effectiveness research frequently employs the instrumental variable design since randomized trials can be infeasible for many reasons. In this study, we investigate and…
Estimating Racial Disparities in Emergency General Surgery
Eli Ben-Michael, Avi Feller, Rachel Kelz +1
Research documents that Black patients experience worse general surgery outcomes than white patients in the United States. In this paper, we focus on an important but less-examined…
Profiling Compliers in Instrumental Variables Designs
Dominik Hangartner, Moritz Marbach, Leonard Henckel +3
Instrumental variable (IV) analyses are becoming common in health services research and epidemiology. IV analyses can be used both to analyze randomized trials with noncompliance a…
Hospital Quality Risk Standardization via Approximate Balancing Weights
Luke Keele, Eli Ben-Michael, Avi Feller +2
Comparing outcomes across hospitals, often to identify underperforming hospitals, is a critical task in health services research. However, naive comparisons of average outcomes, su…
Biased Encouragements and Heterogeneous Effects in an Instrumental Variable Study of Emergency General Surgical Outcomes
Colin B. Fogarty, Kwonsang Lee, Rachel R. Kelz +1
We investigate the efficacy of surgical versus non-surgical management for two gastrointestinal conditions, colitis and diverticulitis, using observational data. We deploy an instr…
