Prognostic score-based model averaging approach for propensity score estimation

BMC Medical Research Methodology
Background Propensity scores (PS) are typically evaluated using balance metrics that focus on covariate balance, often without considering their predictive power for the outcome.

Propensity Score Weighting for Causal Inference with Clustered Data

Journal of Causal Inference, 2018
Propensity score weighting is a tool for causal inference to adjust for measured confounders in observational studies. In practice, data often present complex structures, such as clustering, which make propensity score modeling and estimation challenging.

Influence of initial misdiagnosis on mortality in patients with bacteraemia: propensity score matching and propensity score weighting analyses

BMC Infectious Diseases
Background The diagnostic process is a key element of medicine but it is complex and prone to errors. Infectious diseases are one of the three categories of diseases in which diagnostic errors can be most harmful to patients.

Propensity Score Method for Partially Matched Omics Studies

Cancer Informatics, 2014
This paper focuses on the problem of partially matched samples in the presence of confounders. We propose using propensity score matching to adjust for confounding factors for the subset of data with incomplete pairs, followed by integrating the P ...

Propensity Scores and Palliative Care [PDF]

Journal of Palliative Medicine, 2014
Dear Editor: Understanding nuances of the opportunities for palliative care to improve quality of care while reducing costs is an important topic, and I was glad to see Starks and colleagues approach this issue in their recent article on cost savings of palliative care by different hospital lengths of stay.1 I had several concerns, however, about ...

The performance of different propensity score methods for estimating the effects of multiple treatments or exposures: a neutral comparison study

BMC Medical Research Methodology
Background The generalized propensity score is an extension of the conventional propensity score to settings with a categorical exposure with more than two levels of treatment or exposure.

Covariate adjusted nonparametric methods under propensity analysis

Frontiers in Applied Mathematics and Statistics
Propensity score is one of the most commonly used score functions in adjusting for covariates effect in statistical inference. It is important to understand the impact with propensity score in case some of the prespecified covariates are severely ...

Generalized Propensity Score Matching with Multilevel Treatment Options

Journal of Health Economics and Outcomes Research, 2013
# Background Although conventional form of propensity score matching (PSM) is widely used in outcomes research field, its application on multilevel treatment is limited. # Objectives This article reviews PSM and illustrates their use when there are more

Propensity score matching and randomization

Journal of Clinical Epidemiology, 2015
We used elective total joint replacement (TJR) as a case study to demonstrate selection bias toward offering this procedure to younger and healthier patients.Longitudinal data from 2,202 men were integrated with hospital data and mortality records. Study participants were followed from recruitment (1996-1999) until TJR, death, or 2007 (end of follow-up)
