Communication and Interprofessional Application of Evidence

HS 326 tests communication as a skill with measurable elements: how risks are framed, how evidence is translated for patients and colleagues, and how teams share decisions. Questions ask you to choose the framing or format that preserves understanding, and to identify the team behaviours that make evidence stick.

Communicating risk so it is understood

  • Absolute risks and natural frequencies (for example, '3 in 100 people') are understood far better than relative risk reductions or bare percentages.
  • Use a consistent denominator and time frame; never compare a five-year figure with a one-year figure.
  • Pair every benefit with its harm in the same format; icon arrays and hundred-face diagrams reduce framing effects.
  • State uncertainty explicitly rather than implying precision; a range beats a point estimate.
  • Check understanding with teach-back, asking the patient to restate the plan in their own words, rather than asking whether they understand.

Health literacy and shared decisions

Plain language, chunking, and jargon avoidance raise comprehension; numeracy varies widely, so offer both verbal and visual formats. Decision aids improve knowledge and reduce decisional conflict, but they supplement rather than replace the conversation. Cultural humility and professional interpreter use are part of evidence-based communication, not optional courtesy.

Interprofessional application

Structured tools reduce error: SBAR or ISBAR for handover, closed-loop communication for critical instructions, huddles and briefings for shared mental models, and explicit role clarification at the start of a project. Implementation needs a named owner, a reminder system, and feedback; passive dissemination alone rarely shifts practice. When presenting evidence to a team, lead with the clinical question, the magnitude in absolute terms, the certainty rating, and the recommended action.

Worked example

A colleague says a drug 'cuts stroke risk by 40 percent'. Presented as natural frequencies over ten years: 20 in 1,000 people would have a stroke without treatment and 12 in 1,000 with it, so 8 fewer strokes per 1,000 treated, alongside 3 extra major bleeds. The relative figure is accurate but incomplete; the absolute pair lets the patient weigh the trade-off.

Traps that cost marks

  • Mixing time frames, such as a five-year benefit against a one-year harm.
  • Using 'no evidence of effect' as if it meant 'evidence of no effect'.
  • Presenting only the relative risk reduction because it sounds larger.
  • Assuming a decision aid replaces informed consent or clinical judgement.
  • Disseminating a guideline by email and expecting practice change.
