CARD 04 and CARD 05 - replacing CARD 02 and 03
Reviewed by Dr. Andrea Reidy - Washington University, 2021
Plan
● CARD 04 - outcome measure that identifies patients that had elevated troponin levels (>99th percentile upper reference limit) within 72
hours postoperatively.
● CARD 05 Percentage of high cardiac risk cases with significantly elevated postoperative troponin levels (> 99th percentile URL)
● Sites must submit upper and lower reference limits for each cardiac troponin assay used by their site in order to participate with this
measure.
● Reference limit data can be submitted to the MPOG Coordinating Center as part of the standard lab extract. For sites that are unable to add
to the extract, MPOG will distribute a survey to collect the upper and lower reference limits on an annual basis.
Reality
● Unable to modify the extract to reliably incorporate reference limits.
● Unable to develop process to reliably obtain reference limits manually
Pausing work on these until we can reliably get reference information using automated methods
