Determinants of tracheostomy decannulation: an international survey

Table 3 Multivariable logistic regression analysis of decannulation factors

Factors	Odds ratio (95% CI)^a	P value^a
Clinician factors
Principal work facility
Acute care^b	1.00
Weaning	0.79 (0.45, 1.40)	0.424
Rehabilitation	0.52 (0.26, 1.04)	0.063
Chronic care	0.28 (0.10, 0.77)	0.014
Patient scenario characteristics
Level of consciousness, alert versus drowsy^b	4.76 (3.27, 6.90)	<0.001
Cough effectiveness, strong versus weak^b	3.84 (2.66, 5.54)	<0.001
Secretions, scant thin versus moderate thick^b	2.23 (1.56, 3.19)	<0.001
Oxygenation, 95% saturation, FiO₂ of 0.30 versus FiO₂ of 0.50^b	2.04 (1.45, 2.86)	<0.001

^aOdds ratios with corresponding 95% confidence intervals (CIs) and P values were calculated by multivariable logistic regression analysis using robust estimates of variance and are for the comparison of clinical scenarios in which decannulation was recommended with those in which it was not. Odds ratios of greater than 1.0 favor clinician recommendation for tracheostomy decannulation. Odds ratios of less than 1.0 favor clinician recommendation against tracheostomy decannulation. ^bClinical scenarios with this factor served as the reference group. FiO₂, fraction of inspired oxygen.
