School of Pharmacy, University of Waterloo INTRODUCTION Potentially inappropriate medication use: use of a drug in which the risk of an adverse event outweighs its clinical benefit, particularly when there is evidence in favour of a safer or more effective alternative therapy for the same condition. 1,4 • Half of the seniors taking five or more medications experienced an adverse effect requiring medical attention. 2 This included preventable side effects such as cognitive impairment, and falls which account for a significant portion of emergency room visits and hospitalization. 2,3,4 • The Beer’s criteria 6 , STOPP criteria 7 , and the anticholinergic burden scale 8 have been developed and applied in several different healthcare settings to prevent potentially inappropriate prescribing. CONCLUSION(S) RESULT(S) METHOD(S) ACKNOWLEDGEMENTS ISMP Canada would like to acknowledge support from the Ontario Ministry of Health and Long-Term Care for the development of the Community Pharmacy Incident Reporting (CPhIR) Program (http://www.cphir.ca). The CPhIR Program also contributes to the Canadian Medication Incident Reporting and Prevention System (CMIRPS) (http://www.ismp- canada.org/cmirps/). A goal of CMIRPS is to analyze medication incident reports and develop recommendations for enhancing medication safety in all healthcare settings. The incidents anonymously reported by community pharmacy practitioners to CPhIR were extremely helpful in the preparation of this multi-incident analysis. OBJECTIVE(S) This multi-incident analysis identifies points of intervention in the community setting in order to prevent medication incidents that may compromise patient safety. REFERENCES 1.

Lack of knowledge or awareness of indications and pharmacokinetics Drug Duplications Example) A nursing home patient was on Osto D2 50,000 once daily prior to entering the nursing home. The home recently added Vitamin D 1000 IU daily on top of his existing medications. The patient also takes a daily multivitamin with Vitamin D. He developed Vitamin D toxicity. All vitamin D and calcium was discontinued and adequate hydration was recommended. Physician, pharmacist and nursing staff all missed the multiple sources of vitamin D.” Lack of communication between healthcare professionals Lack of knowledge of generic and brand names Hierarchy of Effectiveness Categories Summary of Recommendations Forcing Functions Setup alert, restrict, or limit certain doses for older adults by programming dispensing software 10 (e.g. dose limits, high alert medications notifications, renally excreted drug reminders) Restrict copying prescriptions in drug dispensing software 5 Automation or Computerization Ensure system is maintained properly and is updated regularly 11 Review severity levels for all drug-drug interaction alerts in pharmacy information systems to balance information needs and to manage “alert fatigue” 11 Implement computer alerts to flag medications within the same class 18 Ensure that all medication information available to patients and practitioners includes the generic and brand name (e.g. medication labels, drug information documents, medication profiles) 7,13 Implement computer mnemonics to minimize selection of the wrong medication (i.e. look a-like/sound a-like drug name pairs) 7,8 Reminders, Checklists, Double Checks Perform independent double checks 11,9 Arrange for better patient care by scheduling follow-up reminders at time of dispensing 10,12 Rules & Policies Education & Information When a prescription is brought into the pharmacy, verify with the patient or caregiver any clinical information about the patient that is necessary to confirm the appropriateness of the medication and dose (e.g. allergies, opioid tolerance, indication for drug) 18 Highlight the importance of look-alike/sound-alike drug names as part of pharmacy staff trainings and internal communication Educate staff/physicians on medication classes with sulfonamide cross-sensitivities Offer a comprehensive medication review for patients to carry with them to their doctor appointments 6 Educate patients on the importance of retaining an updated medication list 5,6 Medical Conditions Example) A doctor wrote a prescription for Zostavax® however the patient had a major contraindication (lymphoma). The injection was stopped immediately before the puncture of the skin. Lack of knowledge to drug- disease interactions Outdated records Intolerance or Allergies Example) A patient previously taking Accupril TM 20mg received a new prescription for Accuretic TM 20mg/12.5mg. During prescription entry, the pharmacy assistant copied the Accupril TM over to Accuretic TM ; however, the patient had a documented sulfa allergy which was missed as a result. Furthermore pharmacist counselling was not done because the patient said "oh yeah, I know all about it”. The patient later that day took a dose of the medication and experienced slight lip swelling which he had to consult a doctor. Accuretic TM was immediately discontinued. Knowledge deficit with sulfonamide cross-reactivity Lack of communication between practitioners for documented intolerances and allergies Assuming the patient knows “all about it” Look-alike, sound-alike drug names at order entry lead to the assumption that both medications were the same. Interactions Between Chronic Medications Example) A patient on both Eliquis © and ASA 81mg was prescribed naproxen for 2 weeks. Patient had an incessant nose bleed that ended up requiring hospital treatment. The interaction wasn't relayed to doctor or staff of nursing home to monitor. Multiple medication use Lack of monitoring and follow-up Alert fatigue Patient Specific Factors Antibiotics & Chronic Medications Example) A significant interaction between sulfamethoxazole/trimethoprim and Warfarin © was missed at order entry and checking but was discovered only when the patient asked. There was an interaction note at the bottom of the prescription hardcopy but was not seen during checking. Faulty computer system that does not pick up on drug- drug interactions Alert fatigue Lack of independent double checks Incomplete patient profile during prescribing Drug Interactions Identified potential contributing factors. Searched ISMP Canada Community Pharmacy Incident Reporting (CPhIR) 14 Database for medication incidents involving drug therapy problems, contraindications, and duplications in patients over 65 years old from 2010 to 2015. 184 incidents met the inclusion criteria and were included in this multi-incident analysis. Analyzed and categorized incidents into two themes and further divided into subthemes. Provided recommendations to fill in patient-safety gaps Selected Incidents for final analysis.
