Pharmaceutical Care and Clinical Pharmacy
Core concepts
Pharmaceutical care is a patient-centered practice: collect a medication history, identify drug-related problems (indication, effectiveness, safety, adherence), and produce a care plan with monitoring. Know the pharmaceutical care process and the difference between medication reconciliation and review. Understand adherence assessment, the pharmacist's role in counseling (teach-back, plain language), and documentation (SOAP notes).
Clinical skills
Be able to interpret laboratory values in context: renal function (eGFR, creatinine), liver enzymes, INR, electrolytes, and blood glucose. Know how to adjust doses in renal or hepatic impairment and how to monitor narrow-therapeutic-index drugs (digoxin, warfarin, lithium, aminoglycosides, vancomycin). Recognize adverse drug reactions (Type A dose-related vs Type B idiosyncratic) and report them through pharmacovigilance systems. Understand special populations: pregnancy, breastfeeding, pediatrics, and the elderly (polypharmacy, Beers criteria).
Traps in questions
- Confusing a side effect with an adverse drug reaction or with a medication error.
- Forgetting to check adherence before escalating therapy.
- Missing that a reported 'allergy' may be an intolerance and needs clarification.
- Overlooking renal dose adjustment when creatinine clearance is provided.
Worked example (rule of thumb)
For any new symptom in a patient on multiple drugs, apply the 'timeline' rule: if the symptom started after the drug was added or dose changed, suspect the drug first. Then assess causality (temporal, known reaction, dechallenge/rechallenge) and document it.
