To evaluate recent trends, we examined longitudinal national data on the outpatient use of warfarin in atrial fibrillation (AF), beta-blockers and aspirin in coronary artery disease (CAD), and angiotensin-converting enzyme inhibitors (ACEIs) in congestive heart failure (CHF).
Previous studies indicate that specific cardiac medications are underutilized.
We used the National Disease and Therapeutic Index (NDTI) (produced by IMS HEALTH, Plymouth Meeting, Pennsylvania) for 1990 to 2002, and the National Ambulatory Medical Care Surveys (NAMCS) for 1990 to 2000 to follow nationally representative samples of outpatient visits. For visits by patients with AF (total n = 14,634 visits), CAD (n = 35,295), and CHF (n = 33,008), we examined trends in the proportion of visits with the selected medications reported.
Warfarin use in AF increased from 12% in 1990, to 41% in 1995, to 58% in 2001 in NDTI; a similar moderation of recent increase was seen in NAMCS. For CAD in NDTI, beta-blocker use increased slowly from 19% in 1990, to 20% in 1995, then to 40% in 2001; NAMCS showed this same pattern. Aspirin use in CAD in NDTI increased from 18% in 1990, to 19% in 1995, to 38% in 2001; NAMCS, however, showed lower use rates. For NDTI, ACEI use in CHF increased from 24% in 1990 to 36% in 1996, but increased to only 39% by 2001, a general pattern also seen in NAMCS.
Both national datasets demonstrate continuing underutilization of these cardiac medications of proven benefit. Although use is increasing, it remains lower than expected, and some increases noted in earlier years have slowed. Substantial public health benefits would result from further adoption of these effective therapies.
为评估近期趋势,我们研究了全国纵向数据,内容涉及心房颤动(AF)患者门诊使用华法林的情况、冠状动脉疾病(CAD)患者使用β受体阻滞剂和阿司匹林的情况,以及充血性心力衰竭(CHF)患者使用血管紧张素转换酶抑制剂(ACEI)的情况。
既往研究表明,某些心脏药物未得到充分利用。
我们使用了1990年至2002年的国家疾病和治疗指数(NDTI)(由宾夕法尼亚州普利茅斯会议的IMS HEALTH公司编制),以及1990年至2000年的国家门诊医疗保健调查(NAMCS),以跟踪具有全国代表性的门诊样本。对于心房颤动患者(共14634次就诊)、冠状动脉疾病患者(共 = 35295次就诊)和充血性心力衰竭患者(共33008次就诊)的就诊情况,我们研究了报告使用所选药物的就诊比例趋势。
在NDTI中,心房颤动患者使用华法林的比例从1990年的12%增至1995年的41%,并于2001年增至58%;在NAMCS中也观察到近期增长趋势有所缓和。在NDTI中,冠状动脉疾病患者使用β受体阻滞剂的比例从1990年的19%缓慢增至1995年的20%,然后在2001年增至40%;NAMCS也呈现出相同模式。在NDTI中,冠状动脉疾病患者使用阿司匹林的比例从1990年的18%增至1995年的19%,并于2001年增至38%;然而,NAMCS显示的使用率较低。在NDTI中,充血性心力衰竭患者使用ACEI的比例从1990年的24%增至1996年的36%,但到2001年仅增至39%,NAMCS也呈现出类似的总体模式。
两个全国性数据集均表明,这些已证实有益的心脏药物仍未得到充分利用。尽管使用率在上升,但仍低于预期,而且早年观察到的一些增长已经放缓。进一步采用这些有效疗法将带来巨大的公共卫生效益。
