|

Abstract
|
|
|
This study has intended to investigate drug information sources which influence physician's prescriptions and to examine how the information sources are related to the physician's characteristic and how often they use them. The ultimate purpose
of
this
study is to help seek the ways of improving the quality of physician's prescriptions. The subjects of the survey are 262 medical practitioners composed of general practitioner, internists, family practitioners, and pediatricians.
While physicians have got drug information most from medical journals, they have got most information on new drugs from pharmaceutical companies. Drug information sources can be classified into two groups : professional sources and commecial
sources.
The study reveals that physicians have obtained more drug information from professional sources than commercial. However, on new drugs the reverse has been true. That is to obtain more information on new drugs from commercial sources.
The commercial sources like pharmaceutical company proved to be the most influential source for physicians to adopt new drugs both at the stage of awareness and adoption. In many cases, the most influential source was the same both at the
awareness
stage and adoption stage.
Physicians in general, are not satisfied with the given amount of drug information. For example, 79% of the study respondents complained of shortage of drug information and 84% pointed out that information on side effects and/or drug interactions
are
the most deficient.
Therefore a drug information system needs to be improved for helping physicians getting sufficient and impartial drug information for their prescriptions of superior quality.
