The effect of a dedicated intensivist staffing to a medical emergency team on airway management in general wards.

Although medical emergency teams (METs) have been widely introduced, studies on the importance of a dedicated intensivist staffing to METs are lacking. A single-center retrospective before-and-after study was performed. Deteriorating patients who required emergency airway management in general wards by MET were included in this study. We divided the study period according to the presence of a dedicated intensivist staff in MET: (1) non-staffed period (from January 2016 to February 2018, n = 971) and (2) staffed period (from March 2018 to December 2019, n = 651), and compared emergency airway management-related variables and outcomes between the periods. Among 1622 patients included, mean age was 63.0 years and male patients were 64.2% (n = 1042). The first-pass success rate was significantly increased in the staffed period (85.9% in the non-staffed vs 89.2% in the staffed; P = .047). Compliance to rapid sequence intubation was increased (9.4% vs 34.4%; P < .001) and vocal cords were more clearly open (P < .001) in the staffed period. The SpO2/FiO2 ratio (median [interquartile range], 125 [113-218] vs 136 [116-234]; P = .007) and the ROX index (4.6 [3.4-7.6] vs 5.1 [3.6-8.5]; P = .013) at the time of intubation was higher in the staffed period, suggesting the decision on intubation was made earlier. The post-intubation hypoxemia was less commonly occurred in the staffed period (7.2% vs 4.2%, P = .018). In multivariate analysis, the rank of operator was a strong predictor of the first-pass success (adjusted OR [95% CI], 2.280 [1.639-3.172]; P < .001 for fellow and 5.066 [1.740-14.747]; P < .001 for staff, relative to resident). In our hospital, a dedicated intensivist staffing to MET was associated with improved emergency airway management in general wards. Staffing an intensivist to MET needs to be encouraged to improve the performance of MET and the patient safety.
