Superficial placement of endotracheal tubes associated with unplanned extubation: A case-control study

Background Unplanned extubation commonly occurs in intensive care units. Various physical restraints have been used to prevent patients from removing their endotracheal tubes. However, physical restraint not only does not consistently prevent injury but also may be a safety hazard to patients. Objectives To evaluate the effect of physical restraint on unplanned extubation in adult intensive care patients. Methods A total of 100 patients with unplanned extubations and 200 age-, sex-, and diagnosis-matched controls with no record of unplanned extubation were included in this case-control study. The 300 participants were selected from a population of 1455 patients receiving mechanical ventilation during a 21-month period in an adult intensive care unit at a medical center in Taiwan. Data were collected by reviewing medical records and incident reports of unplanned extubation. Results The incidence rate of unplanned extubation was 8.7%. Factors associated with increased risk for unplanned extubation included use of physical restraints (increased risk, 3.11 times), nosocomial infection (increased risk, 2.02 times), and a score of 9 or greater on the Glasgow Coma Scale on admission to the unit (increased risk, 1.98 times). Episodes of unplanned extubation also were associated with longer stays in the unit. Conclusions An impaired level of consciousness on admission to the intensive care unit and the presence of nosocomial infection intensify the risk for unplanned extubation, even when physical restraints are used. To minimize the risk of unplanned extubation, nurses must establish better standards for using restraints.

Purpose:Although several studies assess unplanned extubation (UE) in children, few have addressed determinants of UE and factors associated with reintubation in a case-controlled manner. We aimed to identify the risk factors and outcomes associated with UE in a pediatric intensive care unit.Methods:Cases of UE were randomly matched with control patients at a ratio of 1:4 for age, severity of illness, and admission diagnosis. For cases and controls, we also collected data associated with UE events, reintubation, and outcomes.Results:We analyzed 94 UE patients (0.75 UE per 100 intubation days) and found no differences in demographics between the 2 groups. Logistic regression revealed that patient agitation (odds ratio [OR]: 2.44; 95% confidence interval [CI]: 1.28-4.65), continuous sedation infusion (OR: 3.27; 95% CI: 1.70-6.29), night shifts (OR: 9.16; 95% CI: 4.25-19.72), in-charge nurse experience <2 years (OR: 2.38; 95% CI: 1.13-4.99), and oxygenation index (OI) >5 (OR: 76.9; 95% CI: 16.79-352.47) were associated with UE. Risk factors for reintubation after UE included prior level of sedation (COMFORT score < 27; OR: 7.93; 95% CI: 2.30-27.29), copious secretion (OR: 11.88; 95% CI: 2.20-64.05), and OI > 5 (OR: 9.32; 95% CI: 2.45-35.48).Conclusions:This case–control study showed that both patient- and nurse-associated risk factors were related to UE. Risk factors associated with reintubation included lower levels of consciousness, copious secretions, and higher OI. Further evidence-based studies, including a larger sample size, are warranted to identify predisposing factors in UEs.
