Introduction• Antibiotic prophylaxis is useful in reducing incidences of
surgical (operation) site infection.• The use of antibiotic prophylaxis is however characterized
by inappropriate practices such as use of broad-spectrum antibiotics; administering at wrong time; and continuing for too long
• Use of single dose has been found to be as effective as multiple doses and also cost effective to patients [1].
• The recommended duration of prescribed antibiotics prophylaxis for c-section has reduced from ≥ 5 days to 3 days then to 24 hrs and finally to a single dose [2] .
• DUE serves as a structured criteria based method of identifying, monitoring and correcting challenges encountered in practice

Methodology
• DUE criteria developed and endorsed by Mater PTC
• Baseline retrospective review done in Jan- June 2006
• Ongoing Subsequent DUEs were conducted periodically to
date
• Random sampling of C-section cases from medical records• Medical, Theatre and Nursing records, Treatment sheets
were reviewed to identify antibiotic prescribed for each c-section delivery
• Antibiotics prescribed were compared with defined criteria

Feedback & Cost implications• Feedback
– Dissemination to MHPTC, Obs/ Gynae Div & Anaesthetists
– Face to Face, CMEs, profiling individual performance, Use of opinion leaders
– Regular feedback positive change in prescribing trends/ practice
– Positive feedback reinforces good practice and reversed trends
• Cost savings:– Co-Amoxiclav US $ 22.14 per client– Cefuroxime US $ 15.83 per client– Annual extrapolation US $ 13,408
Key Lessons learned• Fear of the unknown- Irrational prescribing • Combination of strategies is critical for sustainable
improvement• Slight policy changes can result in significant cost
savings• Teamwork and mentorship is key in ensuring
continuity of intervention despite staff turnover• Dedication and motivated staff are key in sustaining• Operational research should be integrated into
regular schedule for maximum effectiveness
Implications of DUE• Systematic, criteria-based program of drug use
evaluations (DUE) with feedback on prescribing trends
• Use of single dose for antibiotic prophylaxis is beneficial even in poor resource setting • prolonged antibiotic use does not confer value addition
except in special cases• Optimal medication use in ABX prophylaxis &
Improved patient safety• Adherence to guidelines is a challenge• Wastage & variations in ABX choice that made care
expensive reduced
Future studies• Qualitative studies on underlying causes of lack of
adherence to guidelines • Expand scope of DUEs to additional forms of
surgery• DUEs involving reserve antibiotic use• DUEs of prescribing OI medications in patients on
HAART• Scale up DUEs approach to other MTCs
countrywide
