Session 1 - Intro Flashcards
Purpose / types of health research and study designs
Inductive Reasoning
Make generalised conclusions based on specific scenarios
Observation -> Pattern -> Hypothesis -> Theory
Deductive Reasoning
Start from general statements to reach specific conclusion
Theory -> Hypothesis -> Observation -> Confirmation

Examples Quantitative Variables
(continuous and categorical)
Continuous - height, weight, time, afe, income, questionnaire scale, number of sessions
Categorical - gender, marital status, education, disease severity, group (intervention / control)
Evidence Based Medicine - principles
Conscientious, explicit, judicious use of current best evidence in making decisions about care of individual patients
Integrates individual clinical expertise, and best available external evidence
Hierarchy of Evidence
Hierarchy of Evidence - Research Methods
Systematic review RCTs
RCT
Other controlled clinical trials
Observational studies
Case studies, anecdote, expert opinion
Systematic Review
Uses explicit, systematic methods to collate and synthesise findings of
studies that address a clearly formulated question
● Meta-analyses often form part of systematic reviews but not always
○ Uses statistical methods to combine data from studies
● Studies must be homogenous to combine
● Conclusions only answer specific question and only as reliable as the
studies they include
Case report / case series
May give first indicators of associations for emerging diseases and development of hypothesis
Observational studies - types by ‘when outcomes determined’
After exposure / intervention = cohort study
At the same time = cross sectional study
Before exposure was determined = case-control
