HLTH2024 Research Methods in Health
Focus: Research Questions and Research Designs
Presenter: John Bidewell
Purpose: Match healthcare questions with appropriate research methodologies.
Major healthcare questions that research can answer include:
Clinical practice
Public health and health policy
Research methodologies are tailored to answer these researchable questions.
Purpose of Research: All research seeks to answer a question.
Relevance of the question directly impacts the relevance of the research.
In evidence-based healthcare, research questions focus on improving healthcare practice.
All research should start with a well-defined research question informed by prior knowledge and experiences.
Common questions include:
Does this intervention work?
Is this assessment procedure valid?
What happens if the patient’s condition is not treated?
What are the frequencies and rates of this health condition?
What are the causes and risk factors?
How do individuals with this condition experience life?
Answers to these questions enhance the quality of healthcare through evidence-based practice.
Definition of Intervention: Actions by practitioners to improve healthcare outcomes (e.g., treatments, public health campaigns).
Quantitative Methodology: Intervention studies, including clinical trials and comparative studies, assess effectiveness and impact.
Objective: Determine the accuracy of diagnosis and assessments to classify patient conditions.
Quantitative Studies: Used to validate assessment procedures through diagnostic accuracy studies that measure the validity of these methods.
Purpose: Understand the outcomes if a health condition remains untreated.
Prognostic studies provide essential information about disease progression and survival chances.
Focus: Determine the prevalence and rates of health conditions in populations.
This data is crucial for planning healthcare resources and interventions.
Quantitative epidemiological studies help assess how often conditions occur and who is at risk.
Goal: Identify causes and risk factors for health conditions to develop preventive measures.
Etiological studies often stem from epidemiological findings and focus on establishing cause-and-effect relationships.
Importance: Understanding patient experiences, values, and perspectives is vital for effective healthcare.
Qualitative Methodologies: Explore individual patient experiences and the meanings they ascribe to their health conditions.
Systematic Reviews: Combine results from multiple studies to provide comprehensive insights.
Action Research: Conducted informally in workplace settings to address specific local issues, applying mixed methods approaches.
Healthcare problems can be framed as questions answerable through research.
Research supports evidence-based practice, enhancing job performance in health settings.
A variety of methodologies (quantitative and qualitative) are matched to the specific healthcare questions posed.
