Study Notes
Population Attributable Risk
- Measures disease cases in total population attributable to a specific exposure.
Randomized Controlled Trials (RCT)
- Most powerful single study evidence, though costly and time-consuming.
- Features two groups: Intervention and Control.
- Randomization ensures unbiased group assignment.
- Blinding can be single (patient unaware) or double (both patient and provider unaware).
- Conducted in phases 0-4, with ethical considerations in place.
Number Needed to Treat (NNT) and Number Needed to Harm (NNH)
- NNT: Number of patients needing treatment for one to benefit.
- NNH: Number of patients needing treatment for one to be harmed.
Systematic Reviews & Meta-Analysis
- Systematic review consolidates evidence from multiple studies.
- Meta-analysis mathematically combines results.
- Requires clear inclusion/exclusion criteria and formation of research question (PICO).
- Heterogeneity assessed using inconsistency index.
- Fixed effects assume a common effect, while random effects acknowledge variations across studies.
Biases
- Biases are systematic errors in estimating exposure/outcome relationships.
- Information bias can result from inaccurate participant data.
- Selection bias emerges when participants differ from the broader population.
- Recall bias affects accuracy of reported exposures by patients.
- Observer bias occurs when researchers' expectations shape their observations.
- Misclassification places participants incorrectly in groups.
Confounders vs Effect Modifiers
- Confounder: Associated variable that influences both exposure and disease outcomes.
- Effect modifier: Variable that changes the strength of association between exposure and disease.
- Collider: Influenced by two or more variables, affecting the outcome.
Health Literacy
- Health literacy refers to the ability to obtain and understand health information for informed decision-making.
- Only 12% of U.S. adults have proficient health literacy, often labeled non-compliant.
- Factors influencing health literacy include age, income, education level, minority status, and language barriers.
- Effective strategies include plain language, percentage usage, open-ended questions, and teaching back.
Health Behavior Theories
- Classical conditioning links neutral stimuli with specific responses through reinforcement.
- Operant conditioning involves adding or removing stimuli to reinforce or punish behaviors.
Trans-Theoretical Model (TTM) & Theory of Planned Behavior (TPB)
- TTM outlines stages individuals progress through when changing behavior.
- TPB emphasizes the influence of beliefs about behavior outcome and perceptions of control.
Introduction to Epidemiology
- Types of prevention: Primordial, Primary, Secondary, Tertiary, and Quaternary.
- Key terms: Endemic (background rate), Epidemic (excess in a region), Pandemic (global excess).
- Herd immunity is necessary to control certain diseases, e.g., measles requires 94%.
Epidemiological Measures
- Incidence: New cases relative to at-risk population.
- Prevalence: Total cases within the entire population.
- Mortality: Deaths in a year relative to population size.
- Case fatality: Deaths from a disease relative to total disease cases.
Study Designs
- Case-Control Studies: Observational and analytical, comparing cases with controls based on exposure.
- Cohort Studies: Separate groups based on exposure, can assess incidence and temporal relationships.
- Biases include Neyman’s selection and recall biases.
Absolute Risk and Relative Risk
- Absolute risk reflects the likelihood of developing a disease over time.
- Relative risk compares the incidence of disease between exposed and unexposed groups.
Attributable Risk
- Determines the number of disease cases attributed to a specific exposure.
Social Support and Adherence
- Social support networks are essential for patient healing and compliance.
- Effective strategies to enhance adherence include creating a blame-free environment and improving health literacy.
Transfers and Referrals
- Referrals should prioritize patient needs, with ethical guidelines in place.
- Components of referrals include specifics on the request, supporting data, and patient information.
Social Justice
- Focus on barriers to care, including structural, financial, and cultural challenges.
- Differentiates between equity (fairness) and equality (sameness).
- Addresses various forms of racism affecting healthcare access.
ACA & Healthcare System
- Discusses the structure of Medicare and the Affordable Care Act (ACA).
TeamSTEPPS
- Leadership encompasses situation monitoring and designated leaders for team functions.
- Communication is structured, using SBAR for effective hand-offs.
- Mutual support and conflict resolution strategies, such as the Two-Challenge Rule and DESC method, enhance team dynamics.
