To examine the effects of NEML listing

 “non-essential” medicines (NEM- not listed in
both NEML editions) in the same
pharmacological category

Methodology (cont.)
Comparison
•Statins - 130,287 pt
•ACEIs & AIIAs - 85,349 pt
•Anti-epileptics 31,739 pt
3 major health
insurance schemes
•CSMBS
•SSS
•UC
RESULTS
Utilization Patterns across Health Insurance Scheme
Conclusion
NS
No statistical significant changes in the
utilization patterns of the listed, delisted and
non-listed medicines occurred after the
introduction of the 2008 NEML
Sig .
Discrepancies in utilization were
found among patients in different
health insurance systems.
Ans.
It appears that health insurance policy
exerts greater influence on utilization
patterns than essential medicine
policy.
