Background: Accidental decannulation is a cause of substantial morbidity and mortality in patients in long-term acute care hospitals who require a tracheostomy tube., Objective: To analyze features of accidental decannulation (AD) following placement of a tracheostomy tube, and to implement strategies to reduce the problem., Methods: An analysis of data collected prospectively for quality management in a long-term acute care hospital was performed., Results: AD occurred at a rate of 4.2 ± 0.9/1,000 tracheostomy days over a 7 month period. Factors associated with AD included mental status changes, increased secretions, and change of shift. Following the implementation of a series of interventions (staff education on risk factors for AD and best tracheostomy care practice; increased availability of telemetry and oximetry; and signage to identify patients at high risk of AD), the incidence of AD over a subsequent 7 month period was significantly reduced, to 2.7 ± 1.9/1,000 tracheostomy days. In addition the numbers of multiple, unmonitored, unreported, and night shift ADs were all significantly reduced., Conclusions: Targeted interventions can significantly reduce both the incidence of AD following tracheostomy and associated morbidity. Best practice guidelines to help minimize AD in patients with tracheostomy tubes are proposed.

Optimizing patient-ventilator synchrony is essential in managing patients who require prolonged mechanical ventilation in the long-term acute-care hospital. Inadequate synchrony can increase work of breathing, cause patient discomfort, and delay both weaning and general rehabilitation. Achieving optimal synchrony in the long-term acute-care hospital depends on a number of factors, including adjusting ventilator settings in response to improving lung function; adjusting psychotropic medications to control delirium, anxiety, and depression; and ensuring there is a well positioned correctly sized tracheostomy tube in the airway. The purpose of this review is to provide an update on issues pertinent to patient-ventilator synchrony in the LTACH setting.

Tracheostomy tubes are placed for a variety of reasons, including failure to wean from mechanical ventilation, inability to protect the airway due to impaired mental status, inability to manage excessive secretions, and upper-airway obstruction. A tracheostomy tube is required in approximately 10% of patients receiving mechanical ventilation and allows the patient to move to a step-down unit or long-term care hospital. The presence of a tracheostomy tube in the trachea can cause complications, including tracheal stenosis, bleeding, infection, aspiration pneumonia, and fistula formation from the trachea to either the esophagus or the innominate artery. Final removal of the tracheostomy tube is an important step in the recovery from chronic critical illness and can usually be done once the indication for the tube placement has resolved.

Knowing when to change a tracheostomy tube is important for optimal management of all patients with tracheostomy tubes. The first tracheostomy tube change, performed 1-2 weeks after placement, carries some risk and should be performed by a skilled operator in a safe environment. The risk associated with changing the tracheostomy tube then usually diminishes over time as the tracheo-cutaneous tract matures. A malpositioned tube can be a source of patient distress and patient-ventilator asynchrony, and is important to recognize and correct. Airway endoscopy can be helpful to ensure optimal positioning of a replacement tracheostomy tube. Some of the specialized tracheostomy tubes available on the market are discussed. There are few data available to guide the timing of routine tracheostomy tube changes. Some guidelines are suggested.
