We excluded those who were age 65 and over since they are not eligible for the BCCPTA and we would not observe their medical claims once they were in Medicare.
The major independent variables are the BCCPTA pre/post dummy, the breast cancer dummy, and the BCCPTA interacted with the breast cancer dummy; the latter provides a measure of the DID estimate of the net effect of the BCCPTA.
As noted, we tested alternative post-periods at three months, six months, and one year after initial implementation to see whether the effect of the BCCPTA averaged over the full postperiod was affected by the initial "takeup" of the policy by uninsured women who had gone without care in the pre-BCCPTA period.
3] is the estimate of the DID, which is the net effect of the BCCPTA on the probability of early stage disease for breast cancer patients enrolling in Medicaid.
The interaction term in the linear probability models (shown in Table 3) represents the net effect of the BCCPTA on early disease stage at Medicaid enrollment after controlling for other factors.
First, the data came from a single state and cannot be generalized since each state operates its BCCPTA program differently.
The effects of the BCCPTA only changed slightly when excluding those covariates in the regression models.
In addition to providing better access to cancer treatment by offering a new source of coverage, the BCCPTA also may result in cancer patients enrolling in Medicaid at an earlier stage of their disease.
This study was the first to our knowledge to examine the effect of the BCCPTA on early stage of disease at Medicaid enrollment.
These studies were largely prior to the BCCPTA and likely reflected the longer waiting periods under historical Medicaid criteria.
Another advantage of linked registry and Medicaid files was that we were able to test the potential policy lag by expanding our test of the effect of the BCCPTA from the initial implementation month to up to a year afterward.
In conclusion, the Georgia BCCPTA program successfully helped uninsured low-income breast cancer patients to enroll in Medicaid at an early stage of their cancer to start their treatment, which is crucial for the survival and long-term health benefit of these patients.
