Otolaryngologists were able to decrease the need for cricothyrotomies using specialized techniques for patients with difficult airways. Otolaryngologists bring a special skill set to the DART that is beyond the scope of anesthesiologists and trauma surgeons and that can improve patient outcomes by preventing unnecessary emergency surgical airways.

The root cause analysis (RCA) process is used to investigate adverse events. However, it may not reduce the risk of recurrence as effectively as intended. The authors propose adapting a risk prioritization and reduction process modeled after the Commercial Aviation Safety Team (CAST). The process involves the following: (a) increasing effectiveness of selected interventions by prioritizing each cause/contributing factor based on its role in the current sentinel event as well as in future events; interventions are then selected based on their ability to remediate the root causes/contributing factors and the likelihood of successful implementation; (b) measuring effectiveness of intervention implementation; and ( c) evaluating effectiveness of the interventions by measuring the rates of event recurrence, near misses, contributing factors, mitigating factors, and staff perceptions of risk. Teams that evaluate intervention effectiveness are independent of those that implement the intervention. This framework seeks to improve the RCA process and provide further insights into advancing patient safety.

Background Difficult airway cases can quickly become emergencies, increasing the risk of life-threatening complications or death. Emergency airway management outside the operating room is particularly challenging. Methods We developed a quality improvement program—the Difficult Airway Response Team (DART)—to improve emergency airway management outside the operating room. DART was implemented by a team of anesthesiologists, otolaryngologists, trauma surgeons, emergency medicine physicians, and risk managers in 2005 at The Johns Hopkins Hospital in Baltimore, Maryland. The DART program had three core components: operations, safety, and education. The operations component focused on developing a multidisciplinary difficult airway response team, standardizing the emergency response process, and deploying difficult airway equipment carts throughout the hospital. The safety component focused on real-time monitoring of DART activations and learning from past DART events to continuously improve system-level performance. This objective entailed monitoring the paging system, reporting difficult airway events and DART activations to a web-based registry, and using in situ simulations to identify and mitigate defects in the emergency airway management process. The educational component included development of a multispecialty difficult airway curriculum encompassing case-based lectures, simulation, and team building/communication to ensure consistency of care. Educational materials were also developed for non-DART staff and patients to inform them about the needs of patients with difficult airways and ensure continuity of care with other providers after discharge. Results Between July 2008 and June 2013, DART managed 360 adult difficult airway events comprising 8% of all code activations. Predisposing patient factors included body mass index > 40, history of head and neck tumor, prior difficult intubation, cervical spine injury, airway edema, airway bleeding, and previous or current tracheostomy. Twenty-three patients (6%) required emergent surgical airways. Sixty-two patients (17%) were stabilized and transported to the operating room for definitive airway management. There were no airway management-related deaths, sentinel events, or malpractice claims in adult patients managed by DART. Five in situ simulations conducted in the first program year improved DART's teamwork, communication, and response times and increased the functionality of the difficult airway carts. Over the 5-year period, we conducted 18 airway courses, through which more than 200 providers were trained. Conclusions DART is a comprehensive program for improving difficult airway management. Future studies will examine the comparative effectiveness of the DART program and evaluate how DART has impacted patient outcomes, operational efficiency, and costs of care.

Rapid response teams have become necessary components of patient care within the hospital community, including for airway management. Pediatric patients with an increased risk of having a difficult airway emergency can often be predicted on the basis of clinical scenarios and medical history. This predictability has led to the creation of airway consultation services designed to develop airway management plans for patients experiencing respiratory distress and who are at risk for having a difficult airway requiring advanced airway management. In addition, evolving technology has facilitated airway management outside of the operating suite. Training and continuing education on the use of these tools for airway management is imperative for clinicians responding to airway emergencies. We describe the comprehensive multidisciplinary, multicomponent Pediatric Difficult Airway Program we created that addresses each component identified above: the Pediatric Difficult Airway Response Team (PDART), the Pediatric Difficult Airway Consult Service, and the pediatric educational airway program. Approximately 41% of our PDART emergency calls occurred in the evening hours, requiring a specialized team ready to respond throughout the day and night. A multitude of devices were used during the calls, obviating the need for formal education and hands-on experience with these devices. Lastly, we observed that the majority of PDART calls occurred in patients who either were previously designated as having a difficult airway and/or had anatomic variations that suggest challenges during airway management. By instituting the Pediatric Difficult Airway Consult Service, we have decreased emergent Difficult Airway Response Team calls with the ultimate goal of first-attempt intubation success.
