An overview of the objectives of and the approaches to propensity score analyses.
The assessment of treatment effects from observational studies may be biased with patients not randomly allocated to the experimental or control group. One way to overcome this conceptual shortcoming in the design of such studies is the use of propensity scores to adjust for differences of the characteristics between patients treated with experimental and control interventions. The propensity s...
متن کامل[Propensity score methods for creating covariate balance in observational studies].
Randomization of treatment assignment in experiments generates treatment groups with approximately balanced baseline covariates. However, in observational studies, where treatment assignment is not random, patients in the active treatment and control groups often differ on crucial covariates that are related to outcomes. These covariate imbalances can lead to biased treatment effect estimates. ...
متن کاملComparing treatment effects between propensity scores and randomized controlled trials: improving conduct and reporting.
Evaluating the effectiveness of a therapeutic intervention is ideally carried out in the setting of a randomized controlled trial (RCT). Patients are randomly allocated to the experimental and control groups ensuring that observed, pre-treatment key prognostic characteristics, but also unobserved patient characteristics, are balanced between the treatment groups, minimizing the variability in p...
متن کاملPropensity Score Methods in Nursing Research: Take Advantage of Them but Proceed With Caution.
Intervention research on health outcomes is important to advancing the nursing science. Using randomized controlled trials (RCTs) to estimate intervention (or treatment) effects is optimal for this purpose. Unfortunately, for practical or ethical reasons, RCTs are often not feasible, and thus, researchers often rely on observational or non-RCT data to estimate treatment effects. Such practice p...
متن کاملA comparison of two methods of estimating propensity scores after multiple imputation.
In many observational studies, analysts estimate treatment effects using propensity scores, e.g. by matching or sub-classifying on the scores. When some values of the covariates are missing, analysts can use multiple imputation to fill in the missing data, estimate propensity scores based on the m completed datasets, and use the propensity scores to estimate treatment effects. We compare two ap...
