Therotical part: 

The theoretical part is a series of interactive lectures during which the statisitcal knowledge and scientific principles needed to conduct large database analysis research will presented. The topics covered are: 

  1. Overvue of Nationwide Inpatient Sample (NIS) and Nationwide Emergency Department Sample (NEDS):             - Understanding stratified sampling                                                                                                                                                                             -  NIS and NEDS data elements collected  
  2. Type of studies that can be conducted using NIS/NEDS
  3. Type of studies that cannot be conducted using NIS/NEDS                              
  4. In depth look at the ICD-9 and ICD-10 codes and their correct use                                                                         
  5. Hypothesis testing, p-values and confidence intervals
  6. Confounders and ways to adjust for them
  7. Linear regression (univariate and multivariate)           
  8. Logistic regression (univariate and multivariate
  9. Multivariate analysis model building

  • Basic statistics: mean, proportions, incidence, prevalance, etc...   : This is an optional online lecture that will be available to  participants 2 weeks prior to the workshop. It is highly recommended for participants with limited biostatistics knowledge                                                  

Hands-on part:

During the hands-on part, participants practice all steps involved in large database research:

 - locating NIS online and ordering it

 - Installing NIS on the computer

 - Using the most common STATA commands and do loops:

  • Creating new variables 
  • Deleting and modifying variables
  • Using STATA do loops to define the patient cohort and exposure of interest using ICD-9 codes
  • Using STATS do loops to calculate time from admission to a procedure
  • Calculating totals, means for continuous variables
  • Calculating proportions for dichotomous variables
  • Calculating p-values
  • Adjusting for confounders using linear and logistic regressions

- Participants will also go over the do file of an already published research article step by step to practice all parts of writing a STATA program for a complete research project
