Abstract
We prepared two classes of PDI of different preciseness for each group of antihypertensive drugs on trial: a brief PDI containing actions and effects, brief precautions with a few side effects and a precise PDI containing actions and effects, how to use, precautions and moderately precise side effects.Patients prescribed with one of the antihypertensive drugs were given one of the two classes of PDI and were asked to answer a questionaire at the next visit after two to four weeks.Of the 265 patients who answered the questionaire, 166 were given brief PDIs and 99 were given precise PDIs. 60% of the patients answered “I read the PDI well”, 70% answered “I could understand the actions and effects well”, 71% answered “PDI was useful” .Of 93 patients who had not used drugs completely before, 34% answered that they had come to take drugs more completely after reading the PDI: 55% of the patients for the precise PDI and 24% for the brief one (p<0.01). Description of side effects made 57% of the patients satisfied while 10% of the patients were anxious: 4% for the brief PDI and 20% for the precise one (p<0.05).
This survey suggests that precise PDI with moderate preciseness of side effects makes patients anxious a little, but it makes them rather compliant than noncompliant.From these trial, PDIs were read well and were shown to be usefull using especially the precise ones.
