Let's take a look at Proposition 23, which would tighten the rules at kidney dialysis clinics.
The measure would require dialysis clinics to have at least one physician, nurse practitioner, or physician's assistant present during all operating hours and to report infection data to the state. It would also require operators to get approval from the state before closing a clinic, and prohibits clinics from discriminating against patients based on their type of insurance.
Supporters say Prop 23 will improve patient safety.
But opponents say the changes are unnecessary because they already have the medical staff needed to keep patients safe. They also say adding physicians around the clock would increase costs and possibly force some clinics to close.
The measure is supported by the SEIU-UHW, a labor union for health care workers. It's opponents include the California Medical Association.
