Percentage of patients receiving anesthesia in a non-operating room setting who have end-tidal carbon dioxide (ETCO2) monitored using capnography.
HIGH PRIORITY STATUS:
HIGH PRIORITY TYPE:
This measure is to be reported each time a patient receives anesthesia in a non-operating room setting. End-tidal carbon dioxide (ETCO2) can be recorded in the medical record with either a qualitative (“+”) or quantitative measure (numerical value).
Measure Reporting via the Qualified Clinical Data Registry
CPT codes, type of anesthesia, and patient location are used to identify patients who are included in the measure's denominator. Registry codes are used to report the numerator of the measure.
All patients receiving anesthesia in a non-operating room setting for whom select CPT codes are reported.
Denominator Criteria (Eligible Cases):
Patients receiving anesthesia in a non-operating room setting (Measure response code 1088)
Patient procedures during reporting period (CPT):
00104, 00410, 00731, 00732, 00811, 00812, 00813, 01922
Patients receiving anesthesia in an operating room setting
Patients receiving anesthesia in a non-operating room applicable setting who have end-tidal carbon dioxide (ETCO2) monitored using capnography.
Numerator Note: Operating room is defined as a permanent fixed location in which procedures are performed and is equipped with a dedicated anesthesia machine (mechanical ventilator and inhalational anesthetic delivery system) with standard OR monitors (BP, EKG, pulse oximetry, end tidal CO2). Procedure rooms where anesthesia machines and standard monitors are made available on an “as needed” basis arenot considered operating rooms for the purposes of this measure.
Performance Met: Clinician monitored end-tidal carbon dioxide (ETCO2) using capnography. End- tidal carbon dioxide can be recorded in the medical record with either a qualitative (“+”) or quantitative measure (numerical value). (MEDNAX 53A)
Performance Not Met: Clinician did not monitor end-tidal carbon dioxide using capnography. (MEDNAX 53B)

Use of ETCO2
The use of capnography when administering anesthesia in non-operating room sites is highly variable. To assess current use of capnography in non-OR settings, MEDNAX conducted a random audit of 100 anesthesia cases among all MEDNAX group practices participating in the MEDNAX QCDR. These cases were performed during the first 6 months of 2018 and represented either anesthesia for screening colonoscopy (CPT 00812) or anesthesia for non-invasive radiologic imaging (CPT 01922). In 76% of these cases, anesthesiologists documented use of end-tidal CO2 monitoring while in 24% of cases, such monitoring was not documented.
Anecdotally, monitoring of end-tidal carbon dioxide (ETCO2) occurs in a minority of cases outside of the operating room. This is despite evidence that it reduces hypoxemic events: “Meta-analysis of RCTs indicate that the use of continuous end-tidal carbon dioxide monitoring (i.e., capnography) is associated with a reduced frequency of hypoxemic events (i.e., oxygen saturation less than 90%) when compared to monitoring without capnography (e.g., practitioners were blinded to capnography results) during procedures with moderate sedation (category A1-B evidence).”
Capnography use helps avoid adverse events in numerous settings, including the pediatric emergency room: “Hypoventilation is common during sedation of pediatric emergency department patients. This can be difficult to detect by current monitoring methods other than capnography. Providers with access to capnography provided fewer but more timely interventions for hypoventilation. This led to fewer episodes of hypoventilation and of oxygen desaturation.”3 In addition, monitoring of end-tidal carbon dioxide reduces complications in advanced endoscopic procedures: “Capnographic monitoring of respiratory activity improves patient safety during procedural sedation for elective ERCP/EUS by reducing the frequency of hypoxemia, severe hypoxemia, and apnea.”
Finally, the use of capnography is not only cost efficient, it may create cost savings: “Capnography is estimated to be cost-effective if not cost saving during PSA (procedural sedation/analgesia) for gastrointestinal endoscopy. Savings were driven by improved patient safety, suggesting that capnography may have an important role in the safe provision of PSA
