By popular demand, Ruth Croxford (MSc, PStat, Senior Research Coordinator, Institute for Clinical Evaluative Sciences (ICES), firstname.lastname@example.org) be leading this CSEB webinar on the use observational data. This webinar is considered a follow-up to the successful webinar “Introduction to the Use of Observational Data in Health Services Research” held in December 2013.
Observational data are data that were not originally collected for research purposes. This presentation will focus on the data contained in anonymized versions of the databases used to administer Ontario’s health care system. The timing of this webinar is fortuitous: this spring the Institute for Clinical Evaluative Sciences (ICES) will launch a program that will make the data in these databases available, at marginal cost, to Canadian researchers. The ICES program is part of CIHR’s SPOR (Strategy for Patient-Oriented Research) initiative.
- What is observational data?
- A brief overview of the health care-related administrative databases
- What is a propensity score; how is it calculated
How is the propensity score used to adjust for treatment bias
- Using the propensity score as a covariate in a regression model
- Stratification on the propensity score
- Matched analysis using the propensity score
- Inverse probability weighting
The course will use SAS programming examples to illustrate how the propensity score is calculated and how a propensity score-matched analysis is performed in order to compare two treatments.
Although the programming examples will use SAS, familiarity with the programming syntax (not point and click, but the actual programming) of any statistical languages (e.g. Stata, SPSS, SAS, R) should be enough to follow the examples.
