Time Series Analysis of 30-day Readmission Rates: Program Evaluation and Causality
This seminar will present a time series analysis of 30-day readmission rates using data from the BRIDGES project. The presentation will include a description of times series analysis and how it differs from other analyses of longitudinal data, the use of interrupted times series for program evaluation, how different times series can be cross-correlated to assess whether one series “leads” or “lags” the other, and the concept of Granger causality applied to time series.

He has over 30 years of experience in consulting with investigators in the design and analysis of clinical trials, retrospective and observational studies, and large patient registries. He has considerable experience in the application of general and generalized linear and hierarchical models, classification and tree regression, time-to-event analysis, multivariate analysis, cost-effectiveness analyses and multiple imputation methods for missing data.
Thursday Tech Talks, sponsored by the Delaware Clinical & Translational Science ACCEL program and the Christiana Care Value Institute, are monthly seminars intended to present statistical, epidemiological and bioinformatics methods and how they can be applied to medical research studies. Presentations focus on the technical aspects of methods as well as their application to real world situations.
These free talks are held the first Thursday of each month at noon at Christiana Hospital but can be viewed from your home or office computer. Earn CMEs by participating in-person or online. Lunch is served and all are welcome to attend.
