世纪初期，妇幼保健问题由于关系到妇女与婴儿两个相对弱势且影响整个社会发展稳定的群体而尤为严重，遗传病诊断与产前诊断共同备受关注。基层医院希望得到规范指导，遗传学、妇幼学科专家呼吁出台相关办法进行正确引导。区别于产前诊断相对较明确的管理范围，遗传病涉及人群更广、影响更深远，但同时也面临管理职权和目标不明确的阻碍。因此，遗传学诊断虽然得到了社会各界包括政策制定者的关注，但本身问题的复杂性为问题的解决蒙上了阴霾。研究者接受决策者委托，做了大量科学调研，形成了质量较高的研究报告以及政策方案初稿，同时与决策者进行了大量沟通。但在决策论证时考虑到遗传学领域存在的未知风险，这一份相对完整的政策框架并未得到决策者的重视和认可，遗传学诊断管理办法的出台受到了极大阻滞。以上材料中体现卫生技术评估政策转化的阻力是？
