Upcoming Cardiac-Focused Measure Reviews

• FLUID-01-C review in July 2023

– We are seeking one or two volunteers from

different institutions, to review this measure and

associated colloid use literature

– Commitment:

– Present literature and suggestions at the July

Quality Committee meeting

– Reviewers name will be listed on the

Measure Spec

– Template form

• TEMP-06-C & TEMP-07-C reviews in January 2025

Upcoming Cardiac-Focused Measure Reviews

• FLUID-01-C: Minimizing Colloid Use (Cardiac)

– Definition: Percentage of cardiac cases in which colloids were not administered

intraoperatively

– Rationale: Lack of consistent evidence to suggest improved survival with the use of

colloids as compared to crystalloids in the surgical population. Because colloids

are more expensive than crystalloids, it is recommended that anesthesia providers

avoid the use of colloids in most instances.

GLU-06 Discussion and Preliminary Data

Cardiac Hyperglycemia Avoidance Measure

• GLU-06:

– Percentage of patients, ≥18 years age, who undergo open cardiac surgical

procedures under general anesthesia of 120 minutes case duration or longer for

whom any blood glucose measure did not exceed 180 mg/dL (and not rechecked

within 30-minutes and found to be </=180 mg/dL) was documented.

– Note: open cardiac cases without ANY glucose values documented are flagged

• Timing:

– Start: Anesthesia Start

– End: Anesthesia End

Cardiac Hyperglycemia Avoidance Measure

• Concepts Queried:

• Attribution:

– The provider signed in at the first blood glucose of >180mg/dL.

– In the event that two or more providers in the same role are signed in, both will

receive the feedback.

Glucose MPOG Concept IDs

3361 POC- Glucose (Fingerstick)

3362 POC- Glucose (Unspecified Source)

3405 POC- Blood Gas - Glucose

5003 Formal Lab-Glucose, Serum/Plasma

5036 Formal Lab-Blood Gas, Glucose

Cardiac Hyperglycemia Avoidance Measure

• Inclusions:

– All patients, 18 years of age or older, both with and without diabetes, who

undergo open cardiac surgical procedures (as determined by Procedure Type:

Cardiac phenotype) under general anesthesia of 120 minutes duration or longer.

• Exclusions:

– ASA 6

– Organ harvest (CPT: 01990)

– Non-cardiac cases as defined as those cases not meeting criteria for the cardiac

case type phenotype

– Within the general cardiac case type phenotype, exclude:

Transcatheter/Endovascular, EP/Cath groups and Other Cardiac

– Cases with age <18

Considerations

● Evaluate each high glucose between anesthesia start and end:

○ Blood glucose >180mg/dL is rechecked within 30 minutes and found to be

>180mg/dL = flagged.

○ Blood glucose >180 mg/dL is not rechecked within 30 minutes = flagged.

○ Any case with a glucose >180mg/dL that was rechecked within 30 minutes and found

to be </=180mg/dL = pass.

○ If no high glucose values > 180 mg/dL are documented between anesthesia start and

end = passed.

○ If no blood glucose values are documented for a case = flagged.

● If two blood glucose levels are documented in the same minute, the lower blood

glucose will be considered for this measure

Cardiac Hyperglycemia Avoidance Measure

• Limitations:

– Any glucose checks not entered into the EHR will not be captured

• Remaining Questions:

– Follow-up measure with a caveat for insulin treatment within a specific time

window?

Hypoglycemia Avoidance Counter Measure

• Purpose:

– To ensure this measure is not inducing an increase in hypoglycemia

• Options:

– Also present GLU-02 on the cardiac dashboard

– GLU-02: % of cases with intraoperative glucose < 60 with administration of

dextrose containing solution or glucose recheck within 90 minutes of original

glucose measurement

– Develop a new measure to remove the treatment component and just flag cases

with hypoglycemia

Progress and Next Steps

• Build 1 cardiac-specific measure in 2021 (completed, published 12/2021)

– Post-bypass hypothermia avoidance

• Build 1 cardiac-specific measure in early 2022 (completed, published 11/2022)

– On-bypass hyperthermia avoidance

• Plan and build next measure in mid-2022 and publish in early 2023 (nearly done!)

– Glucose management

• Next measure?

Next Measure Discussion:

• Previous suggested topics include:

– Antibiotic selection and timing

– Neuromuscular blockade reversal

– Pulmonary complication avoidance

– Hypotension avoidance

– Acute kidney injury avoidance

– Handoffs

– Transfusion

– Other ideas?

Cardiac Anesthesia Subcommittee Membership

• Open to all anesthesiologists or those interested in improving cardiothoracic

measures

– Do not have to practice at an active MPOG institution

• Proposed 2023 Meeting Schedule

– April 2023

– August 2023

– November or December 2023

• Thank you for using the forum for discussion between meetings

Thank you!

Glucose Measure Literature/Guidelines:

• In a study of 510 patients undergoing cardiovascular surgery and found the incidence

of AKI to be higher in patients with high HbA1c levels preoperatively; Every 1%

increase over 6% in HgA1c levels increased the risk of renal complications by 24%

• Glycemic variability, a standard deviation of all POC-BG readings, is associated with

increased postoperative LOS-ICU, rise in creatinine, and AKI

• A study including 761 cardiac surgery patients and found that diabetics were at

increased risk of infection and glucose control (120-160 mg/dL) reduced the risk of

wound infection in diabetics

• In a randomized controlled trial, moderate glucose control defined as 127-179 mg/dl

was found to be preferable to tight control ≤ 126 in patients undergoing CABG

Glucose Measure Literature/Guidelines Continued:

• Incidence of AKI was higher in patients with time-weighted average intraop glucose

of >150mg/dl (8%) as compared to patients with blood glucose 110-150 mg/dl (3%)

• KDIGO - recommends maintaining blood glucose between 110 - 149 mg/dL in

critically ill patients

• Tight glucose control (<150mg/dl) is seen as controversial as risks of hypoglycemia

are significant: NICE-SUGAR meta-analysis

• Society of Thoracic Surgeons (STS) Practice Guidelines recommend maintaining

serum glucose levels ≤ 180 mg/dL for at least 24 hours after cardiac surgery

• Guidelines for Perioperative Care in Cardiac Surgery from the Enhanced Recovery

After Surgery Society recommends treatment of blood glucose >160-180mg/dL

with an insulin infusion
