There is little overlap in diagnosis of various ventilator-associated infection. However, the risk factors and outcomes associated with individual criteria are similar, indicating that they may have validity in identifying true pathology. Ventilator-associated infection in general is likely a larger problem than indicated by low hospital-reported rates of ventilator-associated pneumonia. There is clinical confusion due to the presence of several diagnostic criteria for ventilator-associated infection. Developing a more inclusive and clinically relevant criterion for diagnosing ventilator-associated infection is warranted to accurately assess their impact and improve guidance for clinicians in evaluating and treating ventilator-associated infection.

There is a positive correlation between the use of alteplase for malfunctioning central venous catheters and the development of a CASBI. This is likely associated with the presence of an intraluminal fibrin sheath or thrombus. This study adds evidence linking thrombus formation to CBSI.

BACKGROUND: Status asthmaticus is one of the most frequent admission diagnoses in the pediatric ICU (PICU). Collaboration between respiratory therapists (RTs) and physicians may help efficiently deliver care to a patient in status asthmaticus. The Pediatric Asthma Severity Score (PASS) is a measure of severity of a patient's asthma exacerbation at a point in time. The aim of this quality improvement initiative was to establish an RT-driven continuous albuterol weaning protocol using the PASS score. We hypothesized that this would decrease the duration of continuous albuterol without increasing adverse events. METHODS: This was a single-center implementation study in the PICU of a quaternary care children's hospital. Patients with a diagnosis of status asthmaticus who met criteria on continuous albuterol between September 2015 and September 2017 were included. An interdisciplinary team established the protocol, order sets, documentation, and education for involved staff. Qualifying subjects were assessed by an RT per protocol and assigned a PASS score, and the albuterol dose was adjusted on the basis of the PASS score. RESULTS: We compared 104 subjects studied before the implementation of this protocol (September 2015 to August 2016) to 117 subjects after the implementation of this protocol (September 2016 to October 2017). Median (interquartile range) duration of continuous albuterol in the PICU post-implementation was unchanged compared to pre-implementation: 12.1 (7.2-21.0) h versus 11.1 (6-19) h (P ‫؍‬ .22). Median PICU length of stay was also unchanged post-implementation compared to pre-implementation: 19.5 (14.3-29.7) h versus 23.2 (15.2-31.3) h (P ‫؍‬ .16). Using control charts, these processes were stable. There was no difference in adverse events. CONCLUSIONS: An interprofessionally-developed, RT-driven continuous albuterol weaning protocol can be implemented without negatively impacting duration of continuous albuterol or PICU length of stay and without increasing adverse events.
