A household survey investigated the nonprescribed medicine use of 3,481 persons in the Baltimore SMSA in 1968-69. Of respondents, 30 per cent used a nonprescribed morbidity-related medicine in two days. Rates of use are higher for adults, females and whites in all economic classes, and do not increase with increasing severity of morbidity in any economic class. A hypothesis that nonprescribed substitute for prescribed medicines is supported: ill nonprescribed medicine users are less likely to use prescribed medicines or to have visited a physician than nonusers; rates of nonprescribed medicine use are lower for those with a physician visit, and use of both prescribed and nonprescribed medicines for the same purpose is negligible. Lower out-of-pocket costs for visits and prescribed medicines do not lower rates of use. Nonprescribed medicine use is high among healthy and ill suggesting that physicians should inquire into patients' use when evaluating symptoms and before prescribing.
一项家庭调查研究了1968 - 1969年巴尔的摩标准都市统计区3481人的非处方药使用情况。在受访者中,30%的人在两天内使用了与发病率相关的非处方药。所有经济阶层的成年人、女性和白人的使用率更高,且在任何经济阶层中,使用率都不会随着发病率严重程度的增加而上升。非处方药替代处方药这一假设得到了支持:生病时使用非处方药的人比不使用者更不太可能使用处方药或看医生;看过医生的人非处方药使用率较低,且出于相同目的同时使用处方药和非处方药的情况可忽略不计。就诊和处方药的自付费用降低并不会降低使用率。健康人群和患病者中非处方药使用率都很高,这表明医生在评估症状时以及开处方前应询问患者的用药情况。
