怎么理解

crystal_z_y

the steady increase in malpractice litigation has sparked discussions throughout the medical community that polarize patients rights advocates and those seeking to control the cost of malpratice insurance.
为什么discussions 后用throughout ？
medical community that polarize patients rights advocates怎么理解？而且好象与文中后半部分不平行，怎么回事？
谢谢！

medical community that polarize patients rights advocates and those seeking
to control the cost of malpratice insurance.

俩个黑体部分是平行的， 分别指两种人。

我认为 trhoughout the medical community 是介词短语作状语，修饰has sparked。
