  • Address:   1000 Tenth Avenue, New York, NY 10019
  • Database:  National Inpatient Sample (NIS) and National Rreadmission Database  (NRD)

                                           - Largest inpatient and readmission databases in the United States, respectively

                                           - Free access to NRD during and after the workshop

  • Software:  STATA

                                           - Free access to STATA for the duration of the workshop

                                           - Discounted STATA licences for residents and students after the workshop                      

- Longitudinal analysis with NIS: TRENDWT files ,ICD-9/10 codes adjustments, how to use a standard population to control for temporal changes across the years, how to account for inflation over the years using the consumer price index, how to generate trend p values, how to compare two trends over the years (interaction term use in regression analysis)

- How to use multiple imputation to account for missing data
- How to use propensity matching to account for confounders
- How to do survival analysis, Kaplan-Myers curves and cox regression analysis
- How to cheat STATA and shorten the databases to make calculations faster without losing accuracy
- How to use do loops to execute a set of programs over multiple years automatically
- How to change hospital charges to hospital costs, calculate hospital volumes and find the most common diagnoses in a study population
- How to append databases: pointers and pitfalls
- How to use Poisson regression and the log conversion regression for LOS and total costs and charges
- How to use the hospital readmission database (NRD): what are the limitations and assumptions in the database, how to write the do loops to calculate readmission, what are the different definitions of readmissions, how to calculate 30-day mortality, and how to calculate time to readmission for time-to-event analysis, how to perform 12-month follow up for individual patients.  

- All the above commands will be in do files that are ready to use. In addition, we will go over the complete do file of a research project based on NRD and that has been recently published in Gastroenterology, the number one GI journal in the USA by impact factor: 

Abougergi MS, Peluso H, Saltzman JR. Thirty-Day Readmission Among Patients With Non-Variceal Upper Gastrointestinal Hemorrhage and Effects on Outcomes. Gastroenterology 2018 ;155:38-46
