Evidence-Based Practice, Research Literacy, and Safety
Core concepts
Understand evidence hierarchies (systematic reviews/meta-analyses > RCTs > cohort > case-control > case series > expert opinion), study designs, bias types (selection, performance, detection, attrition, reporting), and key metrics: relative risk (RR), odds ratio (OR), absolute risk reduction (ARR), number needed to treat (NNT = 1/ARR), confidence intervals, and p-values. Distinguish statistical from clinical significance.
Traps in questions
- Confusing relative risk with absolute risk-large RR can mean small absolute benefit when baseline risk is low.
- Misinterpreting p-values (probability of data given null, not probability the hypothesis is true).
- Confusing NNT (benefit) with number needed to harm (NNH).
- Assuming a single RCT is definitive-replication and systematic review matter.
- Overlooking publication bias and conflicts of interest.
Worked example / rule of thumb
A trial reports ARR of 2% (from 10% to 8%). Rule of thumb: NNT = 1/ARR = 1/0.02 = 50. Fifty patients must be treated for one additional benefit. Always convert relative to absolute effects to judge clinical value.
Safety integration
Evidence literacy underpins safety: recognize when evidence is insufficient, communicate uncertainty, and apply shared decision-making. Use checklists and documentation for high-risk decisions.
Healthcare Systems, Ethics, Regulation, and Interprofessional Practice
Core concepts
Understand how integrative care fits healthcare systems: reimbursement, licensure, scope of practice, credentialing, and documentation. Know core ethical principles (autonomy, beneficence, nonmaleficence, justice), informed consent, and the duty to disclose uncertainty. Interprofessional practice requires clear roles, communication (e.g., SBAR), and coordination across conventional and complementary providers.
Traps in questions
- Confusing licensure (legal permission to practice) with certification (credential) or scope of practice (what a license permits).
- Overlooking informed consent for complementary therapies-patients must understand evidence and risks.
- Assuming any provider can order or perform any therapy-scope of practice varies by jurisdiction.
- Missing justice considerations: access, cost, and equity in integrative care.
- Ignoring documentation and communication obligations across teams.
Worked example / rule of thumb
A patient asks you to recommend a supplement outside your scope. Rule of thumb: know your scope; refer and coordinate. Disclose limits, provide evidence-informed general information, and connect the patient with a qualified clinician. Document the referral.
Systems integration
Understand reimbursement models, credentialing, and how integrative services are documented and billed. Ethics and communication are tested as applied skills-expect scenario stems.
