Emergency Medicine Research Presentation Transcript

  • 1. Emergency Medicine Research : How do I get started? A/Prof Marcus Ong Consultant, Senior Medical Scientist & Director of Research Department of Emergency Medicine Singapore General Hospital Adjunct Associate Professor Duke-NUS Graduate Medical School Office of Research
  • 2. How do I get started?
    • Step 1:
    • Ask questions about your everyday practice
  • 3.  
  • 4.  
  • 5. How do I get started?
    • Review the current literature:
    • Pubmed/Medline
    • Cochrane database
    • Embase
    • Google scholar
    • Textbooks
  • 6. How do I get started?
    • Step 1a:
    • Frame the question in a way that the answer can be measured:
    • Is HAT better than T&S for scalp lacerations in terms of better wound healing, lower infection and lower wound breakdown?
  • 7. How do I get started?
    • Step 1b:
    • Choose an appropriate study design:
    • RCT
    • Pseudorandomised clinical trial
    • Cohort study
    • Case-control study
    • Observational/descriptive type
  • 8.  
  • 9. How do I get started?
    • Step 1c:
    • Choose appropriate statistical tests:
    • Frequencies, mean, sd, se
    • Chi Square test/ Fisher’s exact test
    • T test
    • Correlation
    • Multivariate analysis, Logistic regression
    • Survival analysis
  • 10. Results Table 1: Characteristics of patients
  • 11. Results Complications by treatment
  • 12. How do I get started?
    • Step 1d:
    • Design and execute your data collection
    • Case record form
    • Survey
    • Computer based data collection
    • Case notes review
    • Warning: Clinicians hate form filling!
