This research discusses teaching Stata to Emergency Medicine residents to improve data accuracy and research knowledge. A manual tailored for EM residents was created to teach basic Stata operations for data entry and import, aiming to reduce errors and make the data usable for analysis. Hands-on experience was emphasized in the training. The study found that teaching Stata enhanced residents' research skills and improved data recording accuracy. However, limitations included the observational nature and small sample size of the study, suggesting the need for a tailored training program for physicians.

  1. Teaching a statistical program in emergency medicine research rotations: Command-driven or click-driven? Muhammad Waseem, MD Research Director Emergency Medicine Lincoln Medical & Mental Health Center Bronx, New York

  2. Disclosure • Financial disclosures: None

  3. Background • Stata is a command-driven program • It is a general-purpose statistical software package used by people of different backgrounds and professional disciplines • Most Stata users are non-physicians

  4. Background • No matter which book you choose or which course you attend…. • Since Stata is used by people in many fields, most training programs offered are geared toward programmers and non-physicians

  5. Background • Although Stata has simple commands, these may be difficult for non-programmers to use • Generally, physicians are familiar with “clicking on” rather than writing commands

  6. Background • Research is an important part of curriculum of emergency medicine residency training • A Research Project is necessary for graduation of EM residents

  7. Background • In order to fulfill this requirement EM residents have a mandatory research rotation

  8. Background • ACGME fully accredited 3 year Emergency MedicineResidency Training Program • 33 EM residents (11 / year)

  9. EM Research Rotation • Formulating a research question • Basic research design • Protocol writing and submission to IRB • Data Collection • Basic statistical concepts

  10. EM Research Rotation • Data recording • Data entry • Data analysis

  11. Background • First step is to organize the raw data into a format which is compatible with Stata

  12. Objectives • Does introduction of a Statistical program (such as Stata) improve the accuracy of data recording and data entry?

  13. Methods • Design: Observational • Setting: Emergency Department of an Urban Teaching Hospital • Participants: Emergency Medicine Residents

  14. Methods • Research Elective • Two blocks of 14 days each • 1-2 per month (1:1 learning)

  15. Methods • Emergency Medicine Stata Manual describing basic operation of Stata created with version 10

  16. Methods • This manual was developed keeping in mind the needs of in-training Emergency Medicine Residents • EM residents mayhave some basic knowledge of statistics but no knowledge of Stata • Emphasis on data entry and data import

  17. Emergency Medicine Stata Manual • Just an introduction designed for first time users

  18. Methods • Teaches EM residents the essential skills for successful data entry and data import to Stata • Purpose is to reduce the number of incorrect entries and make the data set usable to Stata • Hands-on experience using Stata

  19. Methods • Strengths • Tailored to the needs of a specific audience (EM residents) • Discusses only simple and basic operation of Stata

  20. Methods • Weaknesses • Tailored to the needs of a specific rotation (EM residents research elective) • Does not teach residents detailed statistical analysis • Does not discuss programming

  21. Methods • Keep it simple • Utilize pull-down menus (rather than commands) • No discussion on commands

  22. Methods • Getting started • Stata screen • 4 Windows, 9 Tabs

  23. Methods • 4 Windows • Review • Variables • Results • Command

  24. Methods • 9 Tabs • File, Edit, Prefs, Data, Graphics, Statistics, User, Window, and Help

  25. Methods • Basic commands with pull-down menus Describe and summarize data • Data input and output Data Import Saving files

  26. Methods • Describe data • Data editor • Data browser

  27. Conclusions • Basic operation of Stata can be learned quickly by EM residents • Teaching Stata to the EM residents expanded their research related knowledge • Providing introduction of Stata prior to data entry improve accuracy of data recording and facilitates data analysis

  28. Limitations • Observational study • No standardized method • Small sample • Single center study

  29. Implications • It is necessary to develop a training program that addresses the needs of physicians
