To assess changes in isotretinoin prescribing following the implementation of the System to Manage Accutane Related Teratogenicity (SMART) risk management program.
Using nationally representative commercial data resources on prescription drug dispensing patterns, surveys of office-based physician practices, and a large, claims database from a pharmacy benefits manager (PBM), we examined the total number of isotretinoin prescriptions (new and refill), prescriber speciality, and patient characteristics (age, gender, severity of acne indication) in the year before (April 2001-March 2002) and the year following (April 2002-March 2003) implementation of the SMART program.
In the 12-months prior to SMART, 1 508 000 prescriptions were dispensed for isotretinoin, declining approximately 23% to 1 160 000 prescriptions in the year following SMART. There was little or no change in prescriber specialty, severity of acne, and patient age and gender.
SMART may have lead to a decrease in isotretinoin prescriptions. Further research is needed to determine whether the reduced number of isotretinoin prescriptions reflects appropriate use or inhibited use resulting in loss of access to the product's benefits.
评估实施异维A酸相关致畸性管理系统(SMART)风险管理计划后异维A酸处方的变化情况。
利用全国具有代表性的关于处方药配药模式的商业数据资源、对门诊医生执业情况的调查以及一家药房福利管理机构(PBM)的大型理赔数据库,我们研究了在SMART计划实施前一年(2001年4月至2002年3月)和实施后一年(2002年4月至2003年3月)异维A酸处方(新处方和续方)的总数、开处方者的专业以及患者特征(年龄、性别、痤疮适应症的严重程度)。
在SMART计划实施前的12个月里,共开出150.8万份异维A酸处方,在SMART计划实施后的一年中,这一数字下降了约23%,降至116万份。开处方者的专业、痤疮的严重程度以及患者的年龄和性别几乎没有变化。
SMART计划可能导致了异维A酸处方数量的减少。需要进一步研究以确定异维A酸处方数量的减少是反映了合理使用还是使用受到抑制,从而导致无法获得该产品的益处。
