Patient Counseling Techniques Quiz

Drug Interactions

• Medicines help people feel better and stay healthy, but drug interactions can cause problems.
• A drug interaction occurs when one drug's effects are changed by other drugs, herbs, food, or drinks.
• Drug interaction is defined as the change in the pharmacological activity of one drug because of another drug, or other substance.
• Drug interactions happen when patients take more than one drug, often due to a single or multiple disorders, or over-the-counter (OTC) medications.
• Common substances that can cause interactions include caffeine, nicotine, alcohol, herbal medicine, and other drugs.
• Drug interactions can cause a drug's action to decrease, increase, or create adverse effects. The interaction can happen with drugs, food, and/or existing medical conditions.

How Drug Interactions Occur

• Patients frequently take multiple drugs simultaneously for various reasons, such as to treat multiple conditions, or use OTC medications.
• This complexity contributes to the potential for drug interactions.
• Factors contributing to drug interactions include multiple drugs, multiple prescribers, multiple pharmacological effects of the drug, multiple diseases (like hepatic or renal disease), and poor patient compliance.
• Factors also include advanced age or drug-related factors.

Types of Drug Interactions

• Drug-drug interactions occur when two or more drugs react with each other. This is the most common interaction and can cause minor or severe or unexpected side effects.
  • Example: A patient taking pain medication and an antihistamine may experience more drowsiness.
• Drug-food interactions can significantly affect drug absorption in the gastrointestinal (GI) tract.
  • Certain drugs should not be taken with specific foods.
  • Food frequently decreases drug absorption rates.
  • Example: Grapefruit juice inhibits the metabolism of some drugs. It can increase blood levels of atorvastatin, a cholesterol-lowering medication.
  • Example: Foods high in Vitamin K (like broccoli) can reduce the effects of warfarin (an anticoagulant).
• Drug-disease interactions are when a medical condition alters how a drug acts.
  • Example: Over-the-counter oral decongestants like pseudoephedrine can increase blood pressure and be dangerous if the patient has high blood pressure.
  • Drug interactions can increase healthcare costs and potentially lead to injury, hospitalization, or rarely death.

Mechanisms of Drug Interactions

• Drug interactions may be related to pharmaceutical, pharmacokinetic, or pharmacodynamic mechanisms.

• A pharmaceutical interaction occurs before a drug is absorbed systemically (e.g., incompatibility between two drugs mixed in an IV fluid).

• Pharmacokinetic interactions occur when one drug alters the rate or extent of absorption, distribution, metabolism, or excretion (ADME) of another drug, leading to changes in blood concentration and consequently, in the drug's effect.

  • Example: Ketoconazole (an antifungal) can have its absorption reduced by antacids.

• Pharmacodynamic interactions occur when one drug changes the pharmacological effect of another drug in a combination regimen.

  • Example: Isoniazid and rifampin are both hepatotoxic. Taking them together will likely cause more liver damage than if taken separately.

Drug Interaction Categories

• Drug interaction monographs are rated to inform risk levels of combinations of drugs.
  • Risk ratings may be A, B, C, D, or X, where X represents a contraindication.
  • Sometimes listed as Major, Moderate, or Minor interactions.
  • Each rating category (A-X) describes how significant the drug interaction would be.

Drug Interaction Tools

• Online tools like Lexicomp and UpToDate can quickly identify potential drug interactions.

Patient Counselling

• Patient counselling is an interactive conversation about medications tailored to patients' needs. This should include information about the drug's purpose, route of use, dosages, side effects, storage, and precautions. Important information to share includes food/drug interactions, pregnancy status, allergies.
• Effective counselling includes listening to patient concerns, providing appropriate education, and considering potential barriers such as physical space, language, cognitive ability, time constraints, and emotional barriers.

Ways to Improve Counselling Skills

• Actively listen, ask open-ended questions, and provide clear explanations while avoiding quick solutions.
• Be patient and understanding, considering the patient's needs.
• Be aware of any physical barriers, be supportive of the patient's needs, and adapt communication techniques.

Medication Errors

• Medication errors are preventable events that can lead to inappropriate drug use and patient harm.
• Medication errors can happen at many stages of the medication process and prevention strategies are necessary
• Causes of errors include: polypharmacy, oral prescriptions, communication problems, inappropriate drug selection, incomplete/incorrect drug use and lack of computer support.

Patient Compliance

• Patient compliance is the degree to which a patient follows healthcare provider instructions.
• High patient compliance helps to improve patient outcomes and reduce healthcare costs.
• Reasons for poor compliance can be patient-related (like memory problems, feeling better too early), product-related (complicated drug regimens, taste, cost), or pharmacy-related (lack of counselling, time constraints).

The Pharmacist's Role

• Pharmacists play a critical role in improving patient compliance.
• Pharmacists should provide detailed medication information, give adequate counselling, and implement programs (like Pharmaceutical Care Programs).

Communication with Patients

• Effective communication is key to patient counselling.
• Pharmacists improve their communication and listening skills and create strategies to improve the communication between patients and health care providers.

Patient Follow-Up

• Patient follow-up forms track medication, vitals and lab results which support comprehensive patient care.
