– August 3rd, 1pm EST
– December 7th, 1pm EST
• MPOG Retreat in New Orleans, LA
– October 21, 2022
November Meeting Recap
• Reviewed unblinded site performance for ‘general anesthesia in cesarean
delivery’ measures (GA 01/02)
– Subcommittee expressed interest in separating elective vs. non-elective cesarean
cases
– MPOG can separate ASA ‘E’ cases but not necessarily indicative of elective vs.
non-elective
– Many non-elective c-sections do not have an ‘E’ assigned
– SOAP Centers of Excellence recommends reviewing cases that converted to
general anesthesia at an institutional level
– Follow-up question: Would there be interest in developing a list of considerations
for reviewing these cases at your sites?
November 2021 Meeting Recap
Subcommittee discussed the applicability of existing ASPIRE glycemic management measures
for the obstetric population
– Subcommittee recommended excluding cesarean deliveries from all glucose measures
(GLU 01-05)
– After reviewing cases, Coordinating Center proceeded with excluding cesarean deliveries
from hyperglycemia measures (GLU 01/03/05) as this is typically managed outside of the
OR by obstetrician and nursing
– However, we opted to continue to include cesarean deliveries for hypoglycemia measures
(GLU 02/04) at this time due to potential opportunity to improve health system processes
(outside of OB).
– Plan to revisit with Quality Committee & see if attribution might be removed for obstetric
anesthesiologists in the future
Postoperative Nausea
and Vomiting (PONV)
ASPIRE Measures
New Prophylaxis Measure: PONV 05*
• Percentage of patients, aged 18 years and older undergoing a procedure requiring anesthesia and
administered appropriate prophylaxis for postoperative nausea and vomiting, as defined by:
– At least two prophylactic pharmacologic antiemetic agents of different classes administered
preoperatively or intraoperatively for patients with one or two risk factors
– At least three or more prophylactic pharmacologic antiemetic agents from different classes preoperatively
or intraoperatively for patients with three or more risk factors
– For cesarean delivery cases only: At least two prophylactic pharmacologic antiemetic agents from
different classes preoperatively or intraoperatively. (per SOAP ERAS 2021 guidelines)
• Excludes: Labor epidurals
• Risk factors not considered for cesarean delivery patients
• Measure time period: Cesarean delivery start for conversion cases, preop start for scheduled c-sections
*Replaces PONV 01 measure
Postoperative Nausea and Vomiting Measures
• There is no risk score for postoperative nausea and/or vomiting (PONV) in parturients.
• Assessed potential parturient and peri-operative risk factors for PONV.
• Non-smoking, history of PONV after cesarean and/or morning sickness increase risk
• All factors were included in an obstetric-specific risk score (Duke score)
• Both Duke and Apfel risk scores performed poorly in prediction of PONV.
PONV 05 Considerations for Cesarean Deliveries
• Agree on the inclusion criteria for cesarean delivery patients
• Agree with measure time period for administration: Preop start - PACU Start?
• Agree on administering 2 anti-emetics, regardless of number of risk factors?
• Agree with giving any 2 antiemetics from separate classes? Specify which classes must
be given (or not given)?
– For example, propofol infusion is currently included as an acceptable antiemetic
• Do current exclusions apply?
– ASA 5 or 6
– Patients <18 years old (a separate pediatric measure is available)
– Patients transferred directly to the ICU
Unblinded Data Review
Reminders
• Per the terms and conditions outlined during the registration process:
– A culture of openness and trust are critical to the development of such a collaborative effort to
improve quality; and a commitment for confidentiality is required to further the goals of ASPIRE.
– The following examples are to be considered privileged and confidential information and should be
discussed only within the confines of the OB Subcommittee Meeting.
– Any and all patient information.
– Any and all patient identifiers/information which are considered privileged and protected
health information as defined by current HIPAA laws.
– Any specific MPOG QI registry case information.
– Any information discussed regarding a specific site outcome.
– Any reference to a specific MPOG site result or analysis.
– All anesthesiology data presented including but not limited to outcome reports.
– Taking screenshots, pictures or videos of data slides is prohibited.
Site Participation
• All sites that perform cesarean deliveries are presented on the slides to follow (sites
without PACU data excluded)
• Only those sites who have a participant registered for today’s meeting are unblinded
• Quality and OB Champions were notified that unblinded data would be shared and
were given the opportunity to opt out
• No sites emailed us to express a desire to be excluded from this review
Current Outcome PONV Measure: PONV 03
• Percentage of patients, regardless of age, who undergo a procedure and have a
documented nausea/emesis occurrence OR receive a rescue antiemetic in the immediate
postoperative period
• Time period: Recovery room in through 6 hours after Anesthesia End
• Inclusion: Cesarean Deliveries
• Exclusion: Labor Epidurals
• Success: Patient does not report nausea, have an emesis event or receive an antiemetic
during the immediate postoperative period.
• Displayed as an inverse measure: lower is better
Note: Performance for PONV 03/03b was shared with the subcommittee- this was a
confidential session; unblinded data was removed from the presentation before posting.
General discussion topics are noted in the minutes - any comments specific to a site's
performance were omitted from the minutes.
Current Measure: PONV 03b
• Percentage of patients, regardless of age who undergo a procedure and have a documented
nausea/emesis occurrence with or without receiving an antiemetic in the immediate
postoperative period.
• Time period: Recovery room in through 6 hours after Anesthesia End
• Inclusion: Cesarean Deliveries
• Exclusions: Vaginal Delivery Cases & Patients transferred to ICU
• Success: Patient does not report nausea or have an emesis event during the immediate
postoperative period.
• Displayed as an inverse measure: lower is better
PONV 03 and PONV 03b
• Both are already available on the OB Dashboard displayed as filtered to OB
• Recommended modifications for OB?
2022 Planning
Progress in 2021
• Created new postop temperature measure for cesarean deliveries:
TEMP-05-OB
• Created measures focused on general anesthesia rates for cesarean
deliveries
– GA 01: Percentage of cesarean delivery cases where general anesthesia was used
– GA 02: Percentage of cesarean delivery cases where general anesthesia was
administered after neuraxial anesthesia
• Added specific criteria for cesarean deliveries in new PONV prophylaxis
measure: PONV 05
Recap of 2021 Plans
• Sent out survey in late 2020: 9 responses
