1 A 1 in 200 sample of the Southampton electorate was sent a postal questionnaire in January, 1984. Of the 740 adults surveyed, 443 (59.9%) returned completed questionnaires. One hundred and eighty-eight (42.4%) of those replying had been prescribed a medicine within the previous month. 2 Two hundred and seventy-five respondents (62%) felt that not enough was explained about medicines by doctors or pharmacists. 3 Consistent with this, was the fact that 37% were unaware of safe methods of disposal of leftover medicines. In addition, 112 of 154 (72.7%) people currently taking a prescribed medicine knew of no side-effects which could result from this. 4 Eighty-three per cent of respondents thought an information leaflet would be helpful. Of nine items which previous authors had suggested should be included, seven were thought to be important by more than 75% of those replying. 5 Although 54% of people wanted detailed information, 43% stated a preference for short, summarized points. 6 We conclude that most patients need to have more information about prescribed medicines and they would welcome written leaflets. However, further work is necessary to determine the best format for such leaflets.Keywords prescription leaflets patient knowledge side effects Introduction Sooner or later almost everyone has a medicine prescribed by their general practitioner and for many this is a frequent experience. It has been estimated that males visit their general practitioner on average 3.5 times and females 5.0 times annually (Office of Population Censuses and Surveys, 1984). The majority of these consultations end with the issuing of a prescription. In order to derive full benefit and to escape harm from these prescriptions, patients should be aware of their purposes and of any possible hazards; they should be sure of when and how to take their medicines, how to store them and how to dispose of them safely (Herman et al., 1978). Doctors and pharmacists should, between them, make sure that patients receive this information but with over 389 million prescriptions dispensed in 1983 (Office of Population Censuses and Surveys, 1985), both are working against time and often fail to do this (Fletcher, 1973). In any case, verbal advice is often forgotten (Ley, 1979) and technical jargon may confuse patients (Boyle, 1970 1979;George et al., 1983). However, we could discover no recent systematic study of patients' knowledge concerning medicines or of attitudes to prescription information leaflets. We, therefore, decided to carry out our own survey in Southampton.S. Ridout, W. E. Waters & C. F. George about medicines can be improved by the use of simple informative leaflets (Morris & Halperin,
MethodsA questionnaire was designed, piloted and printed (Appendix). It was sent in January, 1984 with a postage-paid return envelope to a 1:200 systematic sample from the latest electoral registers of Southampton Itchen and Southampton Test. A repeat questionnaire was sent to those who had not replied after 1 month.The questionnaire was divided in...
