Final answer:
To reduce healthcare disparities, Flaskerud (2007) highlighted the need for culturally competent healthcare delivery, reflective of the Healthy People 2020 initiative's goal to eliminate disparities and the significance of international assistance in underdeveloped nations.
Step-by-step explanation:
Flaskerud (2007) suggested that to reduce differences in health and healthcare, practitioners need to deliver culturally competent healthcare. Addressing disparities requires understanding the unique needs and perspectives of diverse populations. For instance, the Healthy People 2020 initiative aims to eliminate gender and race disparities in healthcare. Moreover, research suggests a need for mixed-method approaches and community-based participatory action research to better reach and understand hard-to-reach groups. In dealing with the complexities of healthcare systems both in developed and developing nations, organizations like Doctors Without Borders and UNICEF are crucial in assisting with fundamental healthcare services where income and government structures fail to provide.
