Accidental extubations during respiratory management in a children’s hospital

Prevention of neonatal unplanned extubations in the neonatal intensive care unit: a best practice implementation project

BACKGROUND

Adverse events of mechanically ventilated neonates such as unplanned extubations may be associated with serious negative outcomes. Unplanned extubation rates have been monitored by many neonatal intensive care units as a quality of care metric.

OBJECTIVES

The objective was to implement evidence-based best practice and assess the effects of these strategies on minimizing unplanned extubation in the neonatal intensive care unit in a large tertiary children's hospital.

METHODS

Evidence-based audit criteria were used to conduct an audit in the neonatal intensive care unit, Children's Hospital of Fudan University, Shanghai. The program included three phases and was conducted from May 2016 to October 2016. The Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice audit tools for promoting change in health practice were used to ascertain compliance with the criteria before and after the implementation of best practice.

RESULTS

Compared with the baseline audit, the follow-up audit results demonstrated increased compliance rates for securement procedures, documentation of position and security of the endotracheal tube. Compliance for standardized care practice documentation increased from 0% to 100%; compliance for standard care practice implementation increased from 0% to 54.9%; and compliance for staff education increased from 66.7% to 100%. The neonatal intensive care unit also achieved the benchmark of less than one UE per 100 intubation days.

CONCLUSIONS

This implementation project achieved a significant improvement in establishing evidence-based prevention of unplanned extubations in the neonatal intensive care unit of Children's Hospital of Fudan University, China. Standardizing the procedures represented an important step toward refining the quality improvement process.

Effect of Anatomical and Developmental Factors on the Risk of Unplanned Extubation in Critically Ill Newborns

OBJECTIVE

To quantify the daily risk of unplanned extubation (UE) in newborns based on developmental and anatomical factors.

METHODS

Prospective cohort of ventilated newborns over an 18-month period in a level IV neonatal intensive care unit (NICU). We captured UEs through four data streams. We generated multivariable logistic regression models to assess the association of UE with chronological age, birth weight, and postmenstrual age.

RESULTS

During the study, 718 infants were ventilated for 5,611 patient days with 117 UEs in 81 infants. The daily risk of UE had a significant, nonlinear relationship (p < 0.01) with chronological age, decreasing until day 7 (odds ratio [OR]: 0.5; 95% confidence interval [CI]: 0.17–1.47) and increasing after day 7 (day 7–28, OR: 1.36, 95% CI: 1.06–1.75; and >28 days, OR: 1.06, 95% CI: 1.0–1.14). Birth weight and postmenstrual age were not associated with UE. Adverse events occurred in 83/117 (71%) UE events. Iatrogenic causes of UE were more common in younger, smaller infants, whereas older, larger infants were more likely to self-extubate.

CONCLUSION

The daily risk and causes of UE change over the course of an infant’s NICU hospitalization. These data can be used to identify infants at the highest risk of UE for whom targeted proactive interventions can be developed.

Reducing unplanned extubations in the NICU

BACKGROUND AND OBJECTIVES

Unplanned extubation can be a significant event that places the patient at risk for adverse events. Our goal was to reduce unplanned extubations to <1 unplanned extubation per 100 patient-intubated days.

METHODS

All unplanned extubations in the NICU beginning in October 2009 were audited. Data collected included time of day, patient weight, and patient care activity at the time of the event. Bundles of potentially better practices were implemented in sequential Plan-Do-Study-Act cycles. Rates of unplanned extubation (number per patient-intubated day) for each month were analyzed by using control charts, and causes of unplanned extubation were analyzed by using Pareto charts.

RESULTS

We found a significant decrease in the unplanned extubation rate after implementation of the first bundle of potentially better practices in May 2010 (2.38 to 0.41 per 100 patient-intubated days). Several more Plan-Do-Study-Act cycles were conducted to sustain this improvement. A persistent reduction in the unplanned extubation rate (0.58 per 100 patient-intubated days) began in February 2013. Causes included dislodgement during care and procedures and variation in the fixation of the endotracheal tube. The majority of events occurred in very low birth weight infants during the daytime shift.

CONCLUSIONS

Unplanned extubations in the NICU can be reduced by education of staff and by implementing standard practices of care. Sustainability of any practice change to improve quality is critically dependent on culture change within the NICU. We suggest that the benchmark for unplanned extubation should be a rate <1 per 100 patient-intubated days.

Effect of tracheostomy timing in premature infants

OBJECTIVE

To examine if timing of tracheostomy placement in premature infants affects the rates of decannulation and length of time required for mechanical ventilatory support.

MATERIALS AND METHODS

Consecutive case series with chart review of premature patients born at a gestational age of 36 weeks or less at a tertiary-care, academic children's hospital who underwent tracheostomy placement between July 1, 2007 and December 31, 2010 for failure to extubate and chronic lung disease of prematurity. Last follow-up data reviewed was January 1, 2013.

RESULTS

43 patients were identified. 32 patients (74.4%) were able to be weaned from mechanical ventilation by the end of follow-up period, and the average time that elapsed between tracheostomy placement and weaning from mechanical ventilator support was 17.9 months. 19 patients (44.2%) were able to be decannulated, and of those patients, the amount of time between tracheostomy placement and decannulation was 27.9 months. No statistical significance was found in the relationship between tracheostomy timing placement and ability to wean from mechanical ventilator support or decannulate. For those patients able to wean from mechanical ventilator support and get decannulated, no difference in the amount of time and tracheostomy timing was found. Earlier premature patients tended to undergo tracheostomy later in life.

CONCLUSIONS

Decisions regarding tracheostomy placement should be individualized. We were unable to detect a relationship between tracheostomy timing and the ability or duration for premature infants with chronic lung disease of prematurity to wean from mechanical ventilator support or successfully decannulate.

Characteristics and outcome of unplanned extubation in ventilated preterm and term newborns on a neonatal intensive care unit

BACKGROUND

Unplanned extubation events (UEE) are a serious hazard to patient safety, especially on a neonatal intensive care unit (NICU), where reestablishing a secure airway can be difficult. The following study was undertaken to analyze characteristics of UEE and develop prevention strategies.

METHODS

A retrospective cohort study on a level III single center NICU was undertaken. Patient records of a 12-month period from December 2003 to December 2004 were analyzed using a standardized evaluation form. Fischer's exact t-test and the Mann-Whitney U-Ranked Sum test were used for statistical analysis.

RESULTS

One hundred and four neonates with a total ventilation time of 14 495 h were included in this study. Of these patients 12 UEE were observed (1 UEE/1208 h of ventilation time). Neither median birth weight [1445 g (range 460-4650) vs 1755 g (range 460-3570 g)] nor median gestational age [31.5 weeks (range 25.6-39.6 weeks) vs 32.7 weeks (range 23.9-41.5 weeks)] differed significantly between neonates with UEE compared with the total group. When the UEE occurred, the neonates were cared for by experienced nursing staff with a median of 10 years nursing experience. The workload for the individual nurse was high: during shifts when UEE happened, each nurse had to take care of 3.85 patients (range 1.8-5 patients). This workload was higher than the average of 3 (range 1.6-6) patients/nurse during the study period. The most frequently reported reason for UEE was difficult fixation of the tracheal tube (TT) (four patients), followed by handling of the infant by nursing staff or physiotherapy (two patients) or an active infant in whom dislocation of the TT occurred without external manipulations (three patients). In three instances, the reason for the UEE was not documented. Of the 12 UEE observed in 10 patients, three required immediate reintubation, five were managed with nasal continuous positive airway pressure and four did not require further respiratory support. Of those who required support, FiO(2) increased by 14% over baseline compared with the FiO(2) prior to UEE.

CONCLUSIONS

Inadequate TT fixation could be identified as the main contributor to UEE and should be targeted in prevention strategies. The reintubation rate after UEE was only 25%. Overall, UEE did not result in an adverse outcome in terms of mortality. Length of stay on NICU was significantly longer in UEE patients.
