Drug standardization strategies
Lessons learned and continuous discovery

Standard for safe medication practices
 Five rights: Patient, drug, time, dose, and route

Patient safety
 Incomplete information about patient’s

Need to precisely manage patient
medications in the continuum of care
Lack of standard drug nomenclature
Lack of information management process
Interoperability of multiple drug information
systems
Fast evolving of drug products and variations
of nomenclature


Recognized and took action to resolve a medication
information problem
Established a working committee (physicians,
nurses, pharmacists, IT specialists, IT admin)
Consulted with standardized drug databases (e.g.
Health Canada, SNOMED, RxNorm)
Established medication standardization strategies
Developed a data governance policy for future
maintenance of drug database
1. Removing non-prescribed drugs from drug database
2. Correcting misspelled drug names
3. Mapping drug name with drug formula and strength
4. Removing unnecessary use of chemical salts
5. Distinguishing between brand name and generic name medications
6. Correcting combination drug nomenclature
7. Adhering to Health Canada drug nomenclature standards
8. Identifying drug acronyms and other variations
9. Proper labeling study medications
10. Identifying limited use medications

Solution
Drug formula and dosage information will be retained in separate tables from
medication name
Medication name
Tylenol
Generic name
acetaminophen
Brand name
Tylenol
Prograf
tacrolimus
Prograf
Solution
Merging brand name information to the corresponding generic name
Medication Name
hydroxyephedrine w/ normethadone
Proposed Correction
hydroxyephedrine - normethadone
Piperacillin, tazobactam
piperacillin - tazobactam
Other problems
Specifying doses of each drug ingredient in combination drugs
Solution
Using a dash (-) to separate drug ingredients in combination medications
Medication Name
Prograf – LU #173
Proposed Correction
Prograf
Valacyclovir LU #159
Valacyclovir
Problem
• Limited use medications are offered under the Ontario Drug Benefit Program for
specific situations as for a particular medical condition and/or for a limited period
of time (Source: Ontario Ministry of Health and Long-Term Care)
• Physicians are required to review the criteria before writing the three-digit code
Solution
• Removing LU codes from medication names
• Implementing an alert system to notify physicians when LU medications are being
added to patient chart
