Table 2 Summary of the Size of the Source Clinical Data Repository at Each Health Center. Numbers are in Thousands Except Years of Data and Number of Hospitals. Although the PHS Repository Contains Some Data as Far Back as 1986, Significant Amounts do not Start Appearing Until the Early 1990s. Note the Similarities Between BIDMC and CHB Despite Different Patient Populations. Even Adjusted for Number of Patients, the Counts at PHS are Much Higher Because Multiple Data Sources Feed the RPDR, Which Can Result in Duplicate Observations
