January 01, 2019 - QI estimates
were included in the QDR if they reached a threshold defined by a relative standard error … For population counts
based on Claritas data, there is no sampling error. … Standard Error Estimates for Weighted Discharge Rates per 100,000 Population Using
the 2016 Claritas … Consequently, the standard error of the
rate R was calculated as:
SER =100,000 * SES / N. … We multiplied this standard error by 1,000.
