Americans seem to view medical progress as a citizen's entitlement. They expect, and researchers expect to seek, cures for acquired immunodeficiency syndrome (AIDS), Alzheimer's disease, cancer, and other deadly or incapacitating diseases. Both the public and researchers also seem undaunted by the cost. CDS technologies and biotechnology drugs are making this expectation possible. Still, CDSs may not dispel public resentment over the high cost--and profit--of discovering otherwise welcomed new healing molecules. As noted by 1988 Nobel laureate in medicine, Sir James Black: "I think both the press and industry have failed to communicate to the public that behind every little pill is a vast amount of high technology...." With increasing use of and satisfaction from CDSs, more of these mechanisms, covering a broadening spectrum of uses, will be marketed. Because these products are taken less often, patient compliance is expected to increase. As more CDSs are introduced, dispensing frequency will decline and the complexity of prescription drugs will increase. Pharmacists can take advantage of this trend by expanding their activities in the management their patients' medication use.

To investigate recent anecdotal reports of incorrect insulin dispensing, we compared retail pharmacists' and doctors' understanding of commonly used insulin brands. Eighty pharmacists, 29 general practitioners (GPs), and 31 junior hospital doctors were interviewed and completed a questionnaire concerning the duration of action and formulation of 17 insulins. Views on dispensing of alternative insulins were sought from the pharmacists. Fifteen insulin pairs in two columns, 'insulin prescribed' and 'dispense instead', were presented and pharmacists and doctors asked if substitution was appropriate. Mixtard, Penmix and Actrapid were the best understood insulins, Insulatard, Humulin Zn and Protaphane the worst. Both GPs (p = 0.014) and hospital doctors (p < 0.001) scored better than pharmacists. No pharmacist stated that they would routinely dispense alternative insulin, 27 out of 80 not even in an emergency, though 37 were prepared to do so in such a situation after checking, usually with a doctor or in the relevant literature. Sixteen pharmacists, 24 GPs, and all 31 hospital doctors completed the section on insulin pairs but accuracy at identifying appropriate substitutions was poor. These findings coupled with confusing insulin nomenclature may lead to dangerous dispensing errors.
