Lesson learnt
Success of these audits
Alteplase 2 mg/ 2
High cost drug
Product of
AUSPMAN, PMH
Pharmacy
mL frozen syringe
What is the problem:
Audit triggered by:
• Discarded syringes due to cold chain failure
• Retrospective cost analysis:

Alteplase frozen syringes (1/1/10 to 21/3/12
(2 y 2 m)

Audit should provide As:
• Why > use?
• ?Wastage factor (expiry date, incorrect storage)
• ?Adherence to policy + guidelines
AHS Alteplase Guiding Principles:
Restore patency to occluded CVC
Up to 2 doses of Alteplase (2mg) per episode
No efficacy + safety data for > than 2 doses
Method:
Baseline audit (April 2012):
• Retrospective analysis patients given
Alteplase.
• Analytical period:
• April 2011 to March 2012
• Data collection using compliance tools
Post-implementation audit (April 2013):
• Analytical period:
• April 2012 to March 2013

Discussions/Recommendations:
• Baseline Audit:
29% without a valid Rx
45.2% no doc after use
Inappropriate PRN Rx
• Allow the use for 14 doses
without proper review
• Potential for “Nurse
Initiated Med or NIM”
45.2% for locking CVC
• ?ensure future line patency
• No evidence to protect
patency
• Re-audit:
100% valid RX
100% documentation of
use
100% RX in “Once Only
Med” section of NIMC:
• Ensure proper review every
episode of use
• Correct + proper use of
alteplase
Lesson Learnt:
Prevent misuse of alteplase:
• Use “once only” section of NIMC to Rx up to 2
doses of alteplase
• Empowering Renal physician to review the
usage of alteplase every episode:
• Safe + proper use of potential toxic drug
• Prevent misuse (not an NIM)
• $ saving
Conclusion:
Compliance to NSQHS Std 4 (med safety):
4.1 Develop + implement governance
arrangement, policy, procedures and
protocols
4.2 Regular comprehensive assessment to
identify risks + implement system change
4.3 Authorise clinicians to prescribe +
administer meds.
4.5 Undertake quality improvement activities to
enhance med safety
