1. Quality Use of Medicines (QUM) Flashcards
What is QUM?
Quality use of Medicines = QUM is one of the central objectives of Australia’s national medicines policy
Principles of QUM?
• QUM means
o Selecting management options wisely
o Choosing suitable medicines if a medicine is considered necessary and
o Using medicines safely and effectively
• The goal of the national strategy for QUM is to make the best possible use of medicines to improve health outcomes for all Australians
5 Rights of medicine Administration
• Right patient • Right drug • Right dose • Right route • Right time • Additional o Right documentation, Right reason, Right response
Name the three drug information sources?
- AMH - Australian Medical Handbook
- MIMS
- eTG
Difference between drug information sources?
AMH - monographs are on generic names - o Relevant adverse effects o Includes practice points o Does not include pharmacokinetic parameters o Used in clinical setting
MIMS
o Monographs are on product level/brand name
o Difficult to know what monograph to choose
o Need to look at each brand separately
o What the tablet looks like
o Drug interaction tool
o CMIs
o Provided by manufacturer
eTG
o Don’t have drug monographs
o Provides guidelines for management of a range of conditions
o Based on latest available international literature interpreted
What is CMI?
Consumer Medicines information
= leaflet that contains information on the safe and effective use of a prescription medicine.
- Written by the manufacturer of drug - Designed for consumer
Difference between CM and AMH information?
CMI
- Brand names
- Straight forward information with instructions on what to do before and after medication
- Consumer orientated with easier language to be able to understand
AMH
- Designed for administrator to understand what the drug does and how it works
- With harder language
Why might you need to modify a dosage form for administration to patient?
– Children/ Elderly
– Motor neuron and neurological diseases
– Loss of tongue muscles
– Stroke
– NBM – post operative or unconscious
– Unable to coordinate injections or injections
– Tubes in nose or mouth
Ways to modify medication?
– Oral dosage forms
o Crushing
o Dissolving
o Dispersing
– Injections
o Change site
o Change administration type
– Creams and ointment
– Patches (Can’t cut them or modify them)
5 potential issues modifying dosage forms?
– Increase risk of adverse effects. – Result in treatment failure – Altered absorption characteristics o Cannot crush slow release tablets – will lead to over dose as they will get too much at once – Altered medication stability – Failure to reach site of action
Difference between generic and Brand name?
Generic - name of the drug within the medication
Brand - name given buy the manufacture

Difference Between systemic administration and topical administration
Systemic = administered in a way that allows them to be absorbed into the systemic blood circulation
Topical = application to specific body surface areas, where they exert localised effects. (cream or loation)
– These drugs do not require absorption into the systemic blood circulation to be effective
Main routes of administration
Systemic
- Oral
- Parenteral
- Intravenous, subcutaneous, intra muscular, intrathecal, intra-articular
- Rectal (depends on purpose)
- Vaginal (depends on purpose)
Topical
- Dermal
- Inhalation
- Ocular
- Rectal (depends on purpose)
- Vaginal (depends on purpose)
