The impact of mammography quality improvement legislation in Michigan: implications for the National Mammography Quality Standards Act.
OBJECTIVE
This study examined the impact of state legislation on mammography quality and access in Michigan.


METHODS
The impact of state legislation was analyzed with respect to utilization, numbers of machines and facilities, and image quality.


RESULTS
The legislation had a positive effect on image quality improvement, had no impact on utilization by women aged 50 years and above, and resulted in few facility closures.


CONCLUSIONS
Michigan's legislative intervention appears to have had a positive effect on efforts to improve mammography quality assurance with implications for other federal and state efforts to achieve quality assurance in health care delivery.
