PHAR2911 · Pharmaceutics And Professional Practice
Professional Communication & Medication Safety
This chapter is the practice half of PHAR2911: patient counselling, adherence, medication safety and risk communication — the canon that powers the Week-9 Oral Communication & Clinical Decision-Making Assessment and the practice-component written exam. The examined moves are concrete and repeatable: communicate so the message is heard AND understood (teach-back), analyse any error by system theory and the Swiss-cheese model rather than blame, and frame risk with the EPPM 2×2. Examiners grade by section plus a harm flag, so a missed red flag can sink an otherwise polished answer.
What this chapter covers
- 01Communication as a two-way process: empathy, active listening, open vs closed questions
- 02ISBAR handover structure and the patient-centred / biopsychosocial lens
- 03The counselling checklist + teach-back to confirm understanding
- 04Adherence vs compliance vs concordance; written medicines information (CMI)
- 05Medication safety: blame culture vs system theory vs just culture
- 06The Swiss-cheese model of layered dispensing defences
- 07LASA hazards → tall-man lettering, physical separation, barcode scanning, IMS+/PDL reporting
- 08Risk communication with the EPPM 2×2 (threat × efficacy) and harm minimisation
System-theory analysis of a dispensing near-miss
- +1Name the hazard: this is a LASA (look-alike / sound-alike) confusion — an ACTIVE failure occurring at the point of product selection.
- +1Map the layered defences (Swiss-cheese model): computer-generated script → barcode/scan at selection → pharmacist independent double-check → confirm patient name + counsel at handover. The error slipped through the selection layer but its 'hole' did not line up with the double-check layer.
- +1Explain why it was blocked: an error only reaches the patient when holes align through EVERY layer. Here the independent double-check was a solid slice with no aligned hole, so the trajectory was stopped before handover.
- +1Classify the response under just culture: report the near-miss (e.g. IMS+ in NSW, and to PDL), treat it as free system-improvement data, keep accountability without blaming the person, and never normalise the shortcut that created the risk.
- +1Patch the hole (system fix): apply tall-man lettering and physical shelf separation for the confusable pair, and reinforce that the double-check must remain genuinely independent.
Key terms
- Teach-back
- A counselling technique where the patient repeats the plan in their own words (or demonstrates the technique) so the pharmacist can confirm the message was genuinely understood, not merely heard.
- ISBAR
- A structured handover/communication framework — Identify, Situation, Background, Assessment, Recommendation — used to ensure a clinical message is transmitted clearly and completely.
- Adherence
- The extent to which a patient follows a mutually agreed medication plan; the preferred term over 'compliance' (paternalistic) and distinct from 'concordance' (a negotiated, shared agreement).
- Swiss-cheese model
- A system-theory model of safety in which each defence (computer script, barcode scan, pharmacist double-check, name confirmation) is a slice with holes; an error reaches the patient only when holes align through every layer.
- Just culture
- A safety culture that balances blame-free reporting of errors and near-misses with retained accountability — fix the system, never take shortcuts, but do not punish honest mistakes.
- EPPM (Extended Parallel Process Model)
- A risk-communication model crossing threat (susceptibility × severity) with efficacy (response-efficacy × self-efficacy) in a 2×2 grid to select the right behaviour-change strategy.
Professional Communication & Medication Safety FAQ
What is the difference between adherence, compliance and concordance?
Compliance means the patient does as told (a paternalistic term falling out of favour); adherence means the patient follows a plan that was AGREED with them (the preferred term); concordance describes the shared, NEGOTIATED agreement on the plan itself. Note that non-adherence is often intentional — driven by a belief the drug is unnecessary or harmful — so address the belief, not just forgetfulness.
What is the Swiss-cheese model and why does PHAR2911 use it?
It pictures medication safety as several defence layers (computer-generated script, barcode scan, independent pharmacist double-check, patient-name confirmation), each a slice with holes representing latent and active failures. A single hole does little; an error only harms a patient when holes line up through every layer. The course uses it to push you toward system theory — add more, better-staggered defences — rather than blaming an individual.
How do I use the EPPM 2×2 to pick a risk-communication strategy?
Read the patient's THREAT perception (do they feel susceptible, and is it severe?) and their EFFICACY (will the action work, and can they do it?). High threat + high efficacy → danger control, so give a clear actionable solution; high threat + low efficacy → fear control, so build efficacy/educate about the solution; low threat + high efficacy → educate about the risk; low threat + low efficacy ('no response') → educate about BOTH risk and solution.
What are LASA errors and how are they prevented?
LASA = look-alike / sound-alike medicines, whose names or packaging are easily confused — a classic active failure at selection. Remedies include tall-man lettering (capitalising the differing letters), physical separation on the shelf, barcode scanning, and an independent double-check; near-misses are reported via systems such as IMS+ (NSW) and to PDL.
How is the Week-9 oral assessment graded?
It is graded by section across the clinical-decision spine (gather → assess → decide → communicate → safety-net) plus a harm flag: missing a red flag can fail the section regardless of how polished the rest of your answer is. For the exact assessment structure and any weightings, always check your current unit outline.
Exam move
Drill the frameworks until you can name them on cue, because the oral is graded by section plus a harm flag — verbalise which tool you are using ("I'll structure this with ISBAR", "let me check the red flags before I decide", "I'll teach-back to confirm"). Run the clinical-decision spine in a fixed order every time — gather (open questions) → assess (red flags, scope, schedule) → decide → communicate (counsel in order, then teach-back) → safety-net — so you never drop the two things the rubric weights most. For any error or near-miss, answer in system-theory terms: name the hazard (e.g. LASA active failure), map the Swiss-cheese layers, classify under just culture, and finish with the defence you would add. For behaviour-change cases, locate the patient in the EPPM 2×2 first and resist jumping straight to a solution when threat perception is low — raise credible, personalised threat before supplying the efficacy.
