摘要：Medical administrative and EHR data sources offer the potential to ascertain disease and health risk behavior prevalence and incidence, and monitor changes related to public health interventions. This project analyzed several large public and commercial healthcare data sources for their ability to augment public health surveillance by developing indicators of healthcare utilization and preventive services. We also evaluated each data source against important epidemiologic criteria of a surveillance system, such as representativeness, stability, flexibility and timeliness. Our results are discussed in context of the 2009 Health Reform legislation and its impact on healthcare access and utilization.
