Anesthesiologists Cross the Quality Chasm with Point of Care Ultrasound (POCUS) Among Perioperative Patients

Background/Objective: POCUS is an invaluable tool for anatomical variation assessment, guidance of invasive interventions, and diagnosis of critical conditions that may change the anesthesiologist’s plan of care. This technology increases success rate, decreases time to surgery, and maximizes outcomes. The objective of this pilot program evaluation was to identify the anesthesiologists’ systems and processes for utilizing POCUS in clinical decision-making for patients during the perioperative phases of care for improved outcomes. Materials/Methods: A Multivariate Analysis of Variance (MANOVA) was conducted to identify differences across groups (scan type). The independent variable was the type of POCUS examination. The dependent variables included the patient’s: (1) Perioperative Status; (2) Cardiothoracic Anesthesiologist’s Review of Patient History and Formulating the Clinical Question; (3) Overall Risk Potential; (4) Aspiration Potential; (5) Issues Related to Cardiovascular Hemodynamics; (6) Issues Related to Volume Status; (7) Clinical Question Answered by POCUS; (8) Change in Plan of Care; (9) Interventions; and (10) Pharmacological Interventions. Results: MANOVA findings (Wilks’ λ) identified a statistically significant interaction between POCUS scan type and the cardiothoracic anesthesiologist’s clinical decision-making (p < 0.0001). The following four criteria were statistically significant: (1) patients (64%) were examined with POCUS preoperatively (p < 0.05); (2) patients (95%) identified as having some type of overall risk potential (p < 0.05); (3) patients (36%) specifically identified as an aspiration risk (p < 0.0001); and (4) patients (41%) identified with issues related to cardiovascular hemodynamics (p < 0.001). Conclusions: POCUS is a proven imaging modality that is easy, portable, sensitive, and specific for identifying various anatomical landmarks. POCUS utilization in the perioperative setting has potential to have a profound impact on successful surgical completion.
