📖 1. History as Treatment Evidence

🔑 Key Concepts & Definitions

• Patient history : The evidence base for every treatment decision.

★ Must-know

• A patient history identifies what is safe, suitable, and appropriate before treatment.

• A patient history surfaces contraindications and risks, informs realistic expectations and aftercare, and supports continuity and accountability.

Further detail

• A thorough history supports patient safety, effective treatment planning, communication and rapport, and professional and legal protection.

💡 Memory Hook

History evidence → safer decisions, realistic expectations, and accountable care

📖 2. Clinical Reasoning From Fact to Action

📝 Essential Points

• Clinical reasoning connects a piece of information to its implication and then to an appropriate action.

• If a patient takes a photosensitising medication, light-based treatments and strong sun exposure carry greater risk.

📌 When information may have treatment consequences, the practitioner should ask more or seek help rather than guess.

💡 Memory Hook

Fact → risk → ask, modify, defer, or refer → document

📖 3. Medical and Medication History

★ Must-know

• Medical history includes:

  • current and past conditions
  • skin conditions
  • pregnancy or breastfeeding
  • previous procedures

• Medication history includes:

  • prescription medicines
  • over-the-counter products
  • supplements

• Medication history should identify medicines affecting the skin, healing, or sun sensitivity.

Further detail

📌 Practitioners should ask specifically about medications because patients often omit items they consider minor or non-prescription.

📖 4. Allergies and Contraindications

📝 Essential Points

📌 Allergies and contraindications should be screened for every time before treatment.

• Relevant allergies include:
  • product ingredients
  • latex
  • adhesives

📌 When an allergy or contraindication is present, the practitioner should not proceed and may need to modify, defer, or refer.

• Recent or current isotretinoin use, pregnancy, and an active cold sore at the treatment site require follow-up before treatment.

💡 Memory Hook

Allergy present: do not proceed; uncertainty: ask more before deciding

📖 5. Lifestyle and Treatment Planning

★ Must-know

• Relevant lifestyle factors include: sun exposure and protection, occupation, smoking, alcohol, diet and hydration, stress, sleep and exercise, current skincare practices and active ingredients

Further detail

• High stress, poor sleep, frequent gym use, and unnamed tablets are history items requiring follow-up in a patient presenting with breakouts.

📖 6. Referral and Documentation

🔑 Key Concepts & Definitions

• Professional record : Accurate, objective, complete, and contemporaneous.

📝 Essential Points

• 🔄 A referral or information request should include:
  1. the presenting concern
  2. the relevant history
  3. the specific question
  4. the urgency
  5. patient consent before information is shared

📌 A practitioner should refer rather than guess when a question is beyond dermal practice or the case is too complex.

📌 Documentation should record the presenting concern, relevant history, advice given, and consent at the time in a legible and clear form.

💡 Memory Hook

Concern + history + specific question + urgency, with consent before sharing
