The reported impact of human monoclonal IgM antibody (HA1A) on the mor
tality rate from Gram-negative bacteraemia aroused considerable intere
st in its use in Glasgow Royal Infirmary. However, the commercial prep
aration of HA1A was extremely expensive. With this in mind, the Infirm
ary's Drugs and Therapeutics Committee introduced a system whereby the
commercial preparation of HA1A could be introduced in a controlled fa
shion, thereby establishing a model which would encourage targeting th
e prescription of new, highly expensive treatments to appropriate pati
ents. This model provides the clinician with a set of objective criter
ia to be met before prescribing such a preparation, thus preventing un
necessary increases in the hospital drug budget and justifying using e
xpensive resources.
