i. Evaluate each low glucose between anesthesia start and end:
1. If blood glucose <70mg/dL is rechecked within 15 minutes and found to be
<70mg/dL = flagged.
2. If blood glucose <70 mg/dL is not rechecked within 15 minutes = flagged.
3. Any case with a glucose <70mg/dL that was rechecked within 15 minutes
and found to be >/=70mg/dL = pass.
4. If no low glucose values <70 mg/dL are documented between anesthesia
start and end, case is passed.
5. If two blood glucose levels are documented in the same minute, the higher
blood glucose will be considered for this measure (in the case of spurious
values that were rechecked)
6. If no blood glucose values are documented for a case, then the case will be
flagged
ii. Limitations:
1. Any glucose checks not entered into the EHR will not be captured
iii. Remaining Questions:
1. Is the 15 minute recheck window appropriate?
2. Should we amend GLU-06 to shorten the recheck window to 15 minutes as
well? (currently 30 minute recheck window for GLU-06)
h. Preliminary Data shared - See presentation slides.
i. DISCUSSION:
i. Rob Schonberger (Yale) via chat. Complex logic but seems to cover all the bases.
Thanks for this!
ii. Morgan Brown (Boston Children’s) via chat: Is there a way to stratify these glucose
measures based on a diagnosis code of diabetes yes or no? In our young adults, we
have marginally high (180, 190) on CPB, but it drops with no intervention while still
in OR who are non diabetics.
1. Allison Janda (MPOG Cardiac Subcommittee Chair): Would say that although
we could do that stratification, the STS Guidelines don’t specify whether the
patient is diabetic or not - all patients should maintain BG >70 and <180 per
their recommendations
2. Mike Mathis (MPOG Research Director): I wonder if there is an opportunity
to review these flagged cases to identify if it’s a documentation issue or are
these true high-risk hypoglycemia episodes. HIgh-level could we determine
when these failures are occurring - immediately after coming off the pump?
Can we do that as the Coordinating Center at a future meeting?
3. Don Nieter (PERFORM Registry): Anecdotally, I typically only see
hypoglycemia right after heparin is administered.
iii. Don Nieter (PERForm registry) via chat: Is there a way to identify if the % of
hypoglycemia patients received insulin intraoperatively?
1. Allison Janda (MPOG Cardiac Subcommittee Chair): [answered later but
added here for clarity] Yes, we have both the glucose values and insulin
administration in MPOG.
iv. Allison Janda (MPOG Cardiac Subcommittee Chair): Should the artifact recheck time
frame be 15 minutes or 30 minutes?
1. Rob Schonberger (Yale): 15 minutes for hypoglycemia, 30 minutes for
