Abstract:
Background. The introduction of positive drug lists (positive lists)
is part of the regulating mechanisms which
try to reduce the increasing expenditure on drugs. An essential part of these provisions
is at present an analysis of
the trend of drug consumption. The objective of the work was to introduce and evaluate the
method DU 90% which
in analyses of drug consumption uses a 90% ratio of preparations of their total
consumption.
Methods and Results. The analysis was focused on prescriptions in medical
clinics of the General Faculty Hospital.
Classification of drugs according to anatomical, therapeutic and chemical groups and the
use of defined daily doses
made it possible to calculate DU 90% and to prepare a consecutive list of drugs according
to costs in different
departments.
The number of drugs with a defined daily dose was within the range of 280-316. In the
interval DU 90% were
116-142 drugs. In all departments there was a practically identical ratio of drugs which
were part of the positive list.
The greatest expenditure were anti-infectious drugs for systemic use and drugs with an
effect on blood and
haematopoietic organs.
Conclusions. The advantages of the method DU 90% is its easy application,
low cost and possibility to identify
controversial fields. This facilitates further qualitative and quantitative evaluation of
the standard of pharmacothe-
rapy.
Key words:
positive lists, drug consumption.
