“…After the implementation of their qualityimprovement program, the rate of unplanned extubations/100 intubation days dropped from 3.55 to 2.59. Tripathi et al 1 have not provided the statistical significance of this improvement. It is noteworthy to highlight that compared with contemporary qualityimprovement studies with 50 -80% improvement, 3,4,6 a 27% improvement in the unplanned extubation rate is disappointing, since the final unplanned extubation rate remained higher than in other contemporary studies (range: 0.29 -1.5/100 intubation days) 3,4,[6][7][8][9] and also higher than the benchmark reported as acceptable in the literature (Ͻ1/100 intubation days).…”
