Organizational Structures of Health Care Organizations Discussion

Can you help me understand this Health & Medical question?

Looking at the organizational structures of health care organizations, which organizational structure would be best for (a) a community hospital with 200 beds and 175 clinical and professional staff that also owns a home care agency and a nursing home; (b) a medical group practice with 40 doctors and 25 staff members; (c) an assisted living facility with 60 beds, 5 administrative staff and 30 full-time and part-time direct care workers? Please explain your choice for each type of healthcare organization.

What do boards of directors do in healthcare organizations, and why are they important?
