Study Notes
Understanding Research and Statistics in Health Care
- Research outcomes directly inform healthcare practices and policies, supporting evidence-based guidelines and assisting healthcare policymakers.
Types of Studies
- Cohort Studies: examine a group of people over time to understand the development of a condition
- Case-Control Studies: compare people with a condition to those without it to identify potential causes
- Cross-Sectional Studies: observe a population at a single point in time to understand demographics and health trends
- Qualitative Studies: explore thoughts, experiences, and behaviors through non-numerical data
- Systematic Reviews and Meta-Analyses: comprehensively examine and synthesize existing research on a topic
- Mixed-Methods Studies: combine quantitative and qualitative approaches to understand complex research questions
- Case Studies: in-depth investigations of a single person, group, event, or community
- Ecological Studies: examine the relationships between health outcomes and environmental factors at a population level
Study Design and Analysis
- A clear study plan helps maintain focus and relevance in the analysis
- Descriptive studies provide insights into healthcare conditions without inferring causality
- Quasi-experimental and experimental studies assess the efficacy of healthcare interventions
- Observational study designs should consider ethical implications and research objectives
Literature Review
- Begins with reviewing references in bibliographies and online sources
- Helps refine research questions and identify gaps in existing literature
- Critical review of literature establishes credibility in the chosen area
Issues to Identify in Existing Literature
- What is already known about the area?
- Relevant concepts and theories
- Research methods and strategies employed
- Controversies and inconsistencies in findings
- Unanswered research questions
Theoretical or Conceptual Framework
- Establishes a framework for organizing analysis and relating variables
- Uses and tests a theoretical model from research literature
- Connects variables and establishes their relative importance in predicting outcomes
