To compare nurse practitioner (NP) and physician rates of breast and cervical cancer screening among poor, elderly black women.
A quasi-experimental design was used to compare pre- and postintervention annual screening rates. Rates were determined by medical record audits.
Two urban public hospital primary care clinics served as the study sites.
All women aged 65 years or more were eligible to participate.
Women were offered screening by a NP during a routine visit in the intervention site; a physician reminder system was used in the control site.
Baseline annual screening rates were comparable in the two study sites. At the end of the study period, rates were significantly higher in the NP site, compared with the control. In the NP clinic, the annual rate of Pap tests increased to 56.9% from the baseline of 17.8%, and mammographies increased to 40% from 18.3%. In comparison, rates remained low in the control site, increasing only to 18.2% of women receiving Pap tests from a baseline of 11.8%, and remaining at 18% for mammography.
Use of a NP to deliver same-day screening is an effective strategy to target poor, elderly black women for breast and cervical cancer screening. However, even with the substantial increases in rates obtained with the NP intervention, screening in this vulnerable population remains below nationally targeted levels.
比较贫困老年黑人女性中执业护士(NP)和医生进行乳腺癌及宫颈癌筛查的比例。
采用准实验设计比较干预前后的年度筛查率。筛查率通过病历审核确定。
两家城市公立医院的基层医疗诊所作为研究地点。
所有65岁及以上的女性均有资格参与。
在干预地点,女性在常规就诊时由执业护士提供筛查服务;在对照地点则使用医生提醒系统。
两个研究地点的基线年度筛查率相当。在研究期末,与对照组相比,执业护士所在地点的筛查率显著更高。在执业护士诊所,巴氏试验的年度比例从基线时的17.8%增至56.9%,乳房X光检查从18.3%增至40%。相比之下,对照地点的筛查率依然较低,接受巴氏试验的女性仅从基线时的11.8%增至18.2%,乳房X光检查则维持在18%。
由执业护士提供当日筛查是针对贫困老年黑人女性进行乳腺癌及宫颈癌筛查的有效策略。然而,即便通过执业护士干预使筛查率大幅提高,该弱势群体的筛查率仍低于国家目标水平。
