How will Obamacare change health care on Oct 1, 2013?

I am pondering just how Obamacare changes are going to change different aspects of healthcare, starting Oct 1, 2013.

1. How will this change my own healthcare insurance coverage at my hospital?  They have yet to announce this to employees.  Will we change to the new insurance purchase methods?  How expensive is it going to be for employees?

2. How will this change our RN staffing on L&D?  Will it cut out more money from the department budget, creating a loss of jobs?  Will there be more income into the department, creating more RN positions?

3. How will it affect physician/CNM reimbursement?  Reimbursement from insurance companies have been declining in the past 20-25 years.  What an MD used to make from doing one surgical procedure has dropped dramatically.  (I recently was having a discussion with a physician about this at work.)

4. Will more NPs/CNMs/PAs be implemented into the new healthcare system to help save money?

5. With more people being able to buy in to the healthcare insurance exchanges (i.e. more Medicaid??) will we see in influx of more people coming to the hospital for urgent/emergent care?

6. How will this affect hospital billing and reimbursement?

7. Will smaller physician/CNM practices combine into the hospital system and become hospital employees?

8. Will I ever find a job as a CNM in this market?
