There has been growing emphasis on preconception care as a strategy to improve maternal and child health since the 1980s. Increasingly, development of genetic tests will require primary care providers to make decisions about preconception genetic screening. Limited research has been conducted on how primary care providers interpret patients' characteristics and use constructs, such as ethnicity and race, to decide whom to offer preconception genetic screening.
This report assessed the influence of patient characteristics on decisions to offer preconception genetic screening.
A web-based survey of family physicians was conducted. Physicians reviewed a clinical vignette that was accompanied by a picture of either a black or a white patient. Physicians indicated whether they would offer genetic screening, and if yes, what tests they would offer and what factors influenced their decisions.
The majority (69.2%) of physicians reported that they would not offer genetic screening. Respondents who reviewed the vignette accompanied by a picture of the black patient were more likely to offer screening (35% vs. 26%, p = 0.0034) and rated race as more important to their decision to offer testing than those who viewed the picture of the white patient (76% vs. 49%, p < 0.0001).
Our findings suggest that patient race is important to physicians when making decisions about preconception genetic testing and that decision making is influenced by patients' physical characteristics. The reticence of physicians in this sample to offer preconception screening is an important finding for public health and clinical practice.
自20世纪80年代以来,孕前保健作为改善母婴健康的一项策略,受到的重视日益增加。越来越多的基因检测开发将要求初级保健提供者对孕前基因筛查做出决策。关于初级保健提供者如何解读患者特征并利用种族等概念来决定为谁提供孕前基因筛查的研究有限。
本报告评估了患者特征对提供孕前基因筛查决策的影响。
对家庭医生进行了一项基于网络的调查。医生们查看了一个配有黑人或白人患者图片的临床病例。医生们指出他们是否会提供基因筛查,如果会,他们会提供哪些检测以及哪些因素影响了他们的决策。
大多数(69.2%)医生报告称他们不会提供基因筛查。查看配有黑人患者图片病例的受访者更有可能提供筛查(35%对26%,p = 0.0034),并且认为种族对其提供检测决策的重要性高于查看白人患者图片的受访者(76%对49%,p < 0.0001)。
我们的研究结果表明,患者种族在医生进行孕前基因检测决策时很重要,并且决策受到患者身体特征的影响。该样本中医生对提供孕前筛查的沉默态度对公共卫生和临床实践来说是一项重要发现。
