Evaluating Data Accuracy and the Effects of Universal Health Insurance
Massachusetts Cancer Registry
CDC awarded the Massachusetts Cancer Registry (MCR) Comparative Effectiveness Research (CER) funding in September 2010. The purpose of this project is to evaluate the validity and reliability of the primary payer at diagnosis variable for 5,000 randomly selected colorectal and female breast cancer cases diagnosed from 2005 to 2009. Data also will be collected on primary payer at the beginning of each treatment to determine if the patient's insurance status changes during the course of treatment.
Also, Massachusetts enacted universal health care in October 2006, and the MCR will examine the effect of this legislation on insurance coverage before and after its passage. Additionally, race, Hispanic ethnicity, birth country, and tobacco history will be collected to examine their accuracy.
Registry data were important in detailing the epidemiology of colorectal and female breast cancers in Massachusetts for the funding. The results of this audit will help determine how accurate the insurance, race, Hispanic ethnicity, birth country, and tobacco history data are in the MCR. It will also give us the opportunity to evaluate the effects of Massachusetts universal health insurance on cancer treatment.
