Details of inquiries on the suspected contents of the prescriptions were studied from February to April 1980 and from July to September 1981 at 4 university hospital pharmacies. By plotting a x-R control chart of the number of inquiries in each pharmacy, the changes of mean value and variance of the number could be checked quickly. This made possible to take a suitable and immediate action to these changes. Classified by department of consultation, the inquiries received at the internal department gave 40 to 50% of the total inquiries. Furthermore, the inquiries of drugs were about 60% in one pharmacy while the inquiries on amounts of drugs were about 50% in the other pharmacies. This implies that pertinent drug information on the inquiries in each pharmacy should be provided to physicians, primarily to internists.
