MEDICATION SAFETY Meeting HFAP Accreditation Standards for Pharmacy Services and Medication Use Part One HFAP Chapter 25 keeps you in compliance with the Medicare Conditions of Participation Medication Safety Series 1. 2. 3. 4. 5. Prescribing challenges Procurement in an era of drug shortages – keeping it safe Preparation and dispensing – includes sterile preparation Administration of medications – timing, unit dose, bedside medication verification Monitoring of therapy, Medication Use Evaluations Prescribing Challenges Objectives Describe the optimal environment for safe prescribing List the necessary tools for enhancing the knowledge of medications Discuss the advantages and disadvantages of computerized physician order entry (CPOE) The Problem The Institute of Medicine Report revealed that errors in medical care are responsible for many deaths Many health care providers are not aware of their responsibilities Medication errors responsible for numerous adverse outcomes, including death This results in high cost (emotional and financial) Who are the participants?

Medication Prescribing Process: Computerized Prescriber Order Entry (CPOE) – Computer with 3 Interacting Databases • Drug History • Drug Information/Guidelines Database • Patient-Specific Information – Avoids • • • • Illegible Prescriptions or orders Improper Terminology Ambiguous Orders Incomplete Information Schiff GD. JAMA 1998; 279: 1024-9. Computerized Physician Order Entry (CPOE) Provides Decision Support Warns of Drug Interactions – Drug-Drug – Drug-Allergy – Drug-Food Checks Dosing Reduces Transcription Error Reduces number of lost orders Reduces duplicative diagnostic testing Recommends cost effective, therapeutic alternatives CPOE Advantages Automate ordering process Reduces Order Errors – Standardized, legible complete orders – Alerts Data collected on variances in practice Improved Quality CPOE allows for physician reminders of best practice or evidence-based guidelines Indiana University study – Pneumococcal vaccine in eligible patients 0.8% 36.0% – Heparin prophylaxis 18.9% 32% CPOE Disadvantages Errors still possible Alerts Multiple steps Access Dosage Calculations Recognized cause of medication errors Use patient-specific information – height – weight – age – body system function Cohen MR. Medication Errors. Causes, Prevention, and Risk Management; 8.1-8.23. Dosage Calculations: Error Prevention Avoid calculations Cross-checking Cohen MR. Medication Errors. Causes, Prevention, and Risk Management; 8.1-8.23. ISMP Medication Safety Alert 1996; 1 (15). Verbal Orders: Error Prevention Avoid when possible Enunciate slowly and distinctly State numbers like pilots (i.e., “one-five mg” for 15 mg) Spell out difficult drug names Specify concentrations Cohen MR. Medication Errors. Causes, Prevention, and Risk Management; 8.1-8.23. Conflict Resolution Communication is essential No one is right all the time Take the time to listen Beware of instilling an atmosphere of fear Interdisciplinary collaboration Cohen MR. Medication Errors. Causes, Prevention, and Risk Management; 8.1-8.23. Patient Education Educate patients about their medications Purpose of each medication Name of drug, dose, how to take, etc. Provide patients with understandable written instructions Lack of involving patients in check systems Inform patients about potential for error with drugs known to be problematic PRESCRIBING REVIEW Right indication Right drug choice Correct dosage Absence of contraindications – Allergies – Drug interactions (food, other drugs) – Pregnancy and lactation HIGH ALERT MEDICATIONS Insulin Lidocaine Intravenous magnesium sulfate Opiate narcotics Neuromuscular blocking agents Intravenous potassium Intravenous sodium chloride (high concentration) PROBLEMS Lack of knowledge of proper dose Outdated information Illegible handwriting Incomplete orders Use of the apothecary system Order on the wrong chart Nameless prescription PROBLEMS Ordering a total course of therapy instead of daily doses Lack of knowledge about proper routes of administration Ability to bypass controls in automated systems Verbal orders poorly communicated SOLUTIONS Clear handwriting (Print) Avoid abbreviations when errors could occur Prescriber order entry Avoid verbal orders Double check doses Review cases of polypharmacy SUMMARY Prescribing inappropriately can result in serious medication errors. Major advances have been made in improving prescribing safety Technology is our friend Interdisciplinary interactions go a long way toward preventing errors NEXT SESSION Medication procurement in an era of medication shortages Compounding pharmacies – friend or foe?
