Structures of Medical Practices Explain the structures of medical practices (e.g., solo practice, group practice, or multispecialty groups). Research your own geographic region (town, city, county, or state) to find out the most predominant structure found in your community and provide insight into why that structure emerged as the prevailing way to organize office-based medical care. Impact of Law on Practices Explain how the Patient Protection and Affordable Care Act, commonly called the ACA, will impact the type of practices in your area. Do you believe that practices will change their structure to accommodate the new law? Why or why not?
