Cephalosporin and aminoglycoside utilization in different parts of the world.
Cephalosporin and aminoglycoside utilization in Hong Kong during 1984, 1985 and 1986, were evaluated from wholesale data and compared with corresponding Swedish statistics and with UK data from a survey of non-hospital prescriptions. Details regarding each drug and category were collated, adjusted for population and if appropriate expressed as defined daily doses (DDDs)/1000 inhabitants/day. With respect to cephalosporins: (a) overall sales (especially those of the newer and more expensive parenteral drugs) were increasing; (b) parenteral sales were much larger in Hong Kong hospitals than in the community (up to about 106 versus 16 kg/million inhabitants/year respectively), but in Sweden they were comparable (up to about 38 and 41 kg/million inhabitants/year respectively); (c) non-hospital oral utilization appeared greater in the UK than in Sweden and Hong Kong (up to about 0.7, 0.4 and 0.4 DDDs/1000 inhabitants/day respectively); (d) oral sales to hospitals were greater in Hong Kong than Sweden (up to 0.3 compared to 0.1 DDDs/1000 inhabitants/day respectively) and (e) oral paediatric formulations (liquids) were most popular in Hong Kong, a higher proportion of children in Hong Kong being one possible reason. Non-hospital sales of gentamicin and kanamycin in Hong Kong were much greater than in Sweden (up to about 0.20 and 0.06 vs. 0.01 and 0.00 DDDs/1000 inhabitants/day respectively), whereas UK utilization appeared almost non-existent. Topical neomycin sales in Hong Kong were much more popular than in Sweden (up to about 60 vs. 9 g/million inhabitants/day). These regional differences in antibiotic utilization may be related to respective health care systems (and thus the affordability and availability of drugs) and prescribing preferences (cultural and/or promoted by drug companies), quite apart from possible differences in drug efficacy, drug tolerance and the prevalence and severity of various infections.
