To determine if revenue generated from pharmaceutical advertisements in medical journals creates potential financial conflicts of interest for nonprofit physician organizations that own those journals.
Convenience sample of six professional medical societies and their respective journals. Calculation of pharmaceutical advertising revenue generated by these journals for their respective professional medical societies.
Random selection of each journal for one month per quarter in calendar year 1996 and tabulation per edition of the average number of pharmaceutical advertising pages for each journal.
Published advertising rates were used to estimate pharmaceutical advertising revenue for calendar year 1996 and compared with each organization's gross revenue and membership dues and assessments, based on Internal Revenue Service documents for the last available fiscal year (1995).
Estimated pharmaceutical advertising revenue ranged from $715,000 to $18,630,000. Five organizations raised more than 10% of their gross income (range 2% to 30%) from a single journal's pharmaceutical advertising. Four organizations raised as much or more from pharmaceutical advertising as from members (range 17% to 790%).
Potential financial conflicts of interest arising from pharmaceutical advertisements in medical journals may be substantial. The impact on professional societies' financial independence and behavior is unknown.
确定医学期刊上的药品广告所产生的收入是否会给拥有这些期刊的非营利性医师组织带来潜在的财务利益冲突。
选取六个专业医学协会及其各自期刊的便利样本。计算这些期刊为各自专业医学协会产生的药品广告收入。
在1996年日历年中,每季度随机选取每个期刊一个月,并统计每个期刊每期的药品广告页面平均数量。
使用公布的广告费率来估算1996年日历年的药品广告收入,并根据美国国税局(Internal Revenue Service)提供的最近一个可用财政年度(1995年)的文件,将其与每个组织的总收入、会员费和会费评估进行比较。
估计的药品广告收入从71.5万美元到1863万美元不等。五个组织从单一期刊的药品广告中获得的收入超过其总收入的10%(范围为2%至30%)。四个组织从药品广告中获得的收入与从会员那里获得的收入一样多或更多(范围为17%至790%)。
医学期刊上的药品广告引发的潜在财务利益冲突可能很大。对专业协会财务独立性和行为的影响尚不清楚。
