Drug utilization in paediatrics: non-medical factors affecting decision making by prescribers.
The study was done to show that in certain areas of paediatric pharmacotherapy unexpected discrepancies may arise between accepted therapeutic principles and the actual behaviour of a prescribing doctor. The first example was of a great reduction in penicillin use in a university teaching hospital after certain therapeutic accidents: in one year, there were 2 fatal cases of rhabdomyolysis due to use of procaine benzyl-penicillin. Other antimicrobial drugs inferior to penicillin, such as lincomycin and sulphonamides, replaced penicillins. The second example showed the inverse relationship between the use of antitussives and other drugs in symptomatic treatment of respiratory diseases in outpatients and inpatients; the pressure of unduly optimistic expectations of therapy imposes a high prescribing rate of these drugs in the outpatient population, in contrast to hospitalized patients, whose doctors, being spared such pressure, prescribe antitussives far less often. The third example demonstrates the possibility of inadequate education in the use of antimicrobial drugs. Although doctors from regional hospitals receive their training at an university hospital, they tend to prescribe chloramphenicol ten times more per bed-day than their colleagues in an university hospital. In terms of the cost/effectiveness ratio, a high prescribing rate of cephalosporins is not economically favourable in a university teaching hospital. It is also shown that studies of drug utilization in children are feasible if age--appropriate adaptation of the statistical value expressed as the defined daily dose is performed. The adaptation was evaluated by comparing pharmacy-based drug consumption data expressed in "paediatric defined daily doses", with actual days of treatment with particular drugs, i.e. data from patient records for 244 beds in the University Teaching Hospital.
