Which econometric method should you use for causal inference of health policy?

TL;DR A paper by Ress and Wild (2024) provide the following recommendations in answering this question. When aiming to control for a large covariate set, consider using the superlearner to estimate nuisance parameters. When employing the superlearner to estimate nuisance parameters, consider using doubly robust estimation approaches, such as AIPW and TMLE. When faced with…

What is ‘Bayesian Hierarchical Modelling’ and how can it be used to evaluate oncology treatments studied in basket trials?

Should payers cover a new oncology treatment targeting specific biomarkers across multiple tumor types? One the one hand, one could require a separate trial for each tumor type. While this would be convincing evidence, it also is very expensive to conduct clinical trials for every tumor type, particularly if treatment efficacy is homogenous across tumor…

Imputing deductibles in claims data

Many researchers are interested in how cost sharing impacts health care utilization, cost and patient outcomes. This is especially true as high-deductible health plans (HDHP) have become more common in the US. In 2023, 29% of covered workers in the US had a HDHP. One helpful type of data for analyzing HDHPs is claims data.…

PREFER recommendations for patient preference studies

Patient preferences should be the most important part of health care decisionmaking. However, third parties often make decisions for patients. Physicians make decisions for patients due to asymmetric information (i.e., physicians are experts; patients typically are not). Payers make decisions for patients since–in most developed countries–third-party payment cover most of the cost. Moreover, in some…
