Dr. Chen should focus her attention on the policy level of the four levels of the healthcare system. The four levels typically include:
- Individual Level: Focused on patients and their health needs.
- Community Level: Involving local health organizations and community resources.
- Organizational Level: Pertaining to healthcare institutions and their practices.
- Policy Level: Related to laws, regulations, and policies that govern healthcare systems.
Since Dr. Chen believes that an outdated regulation is harming her patients, addressing the policy level would be crucial for advocating for policy change or reform. This could involve engaging with policymakers, presenting evidence-based arguments, and mobilizing support from other healthcare professionals or stakeholders.
