Implementation and assessment of an electronic clinical decision support tool to notify clinicians of critical hyperbilirubinemia in preterm neonates less than 35 weeks' gestation.

OBJECTIVES: Critical hyperbilirubinemia in preterm neonates, a condition requiring greater attention, is treated with phototherapy or exchange transfusion when bilirubin results exceed gestational age and age-specific medical decision levels (MDLs) to prevent bilirubin-induced neurologic damage. Conventional evaluation involves multiple manual steps and is poised to inconsistencies and delays. METHODS: We designed and implemented an electronic clinical decision support (CDS) tool to identify and alert neonatal intensive care unit clinicians of critical hyperbilirubinemia with a SmartZone alert. We evaluated the performance of our manual evaluation workflow, the accuracy of the electronic CDS tool, and the outcome of the electronic CDS tool to reduce the time to place orders for interventions. RESULTS: Among the 22 patients who met the criteria to have phototherapy ordered before implementing the electronic CDS tool, 20 (90%) had phototherapy ordered. Fourteen (70%) phototherapy orders were placed less than 24 hours, 4 phototherapy orders were placed 24 to 72 hours, and 2 orders were placed more than 72 hours after bilirubin results exceeded the corresponding MDLs. Among the 15 patients who met the criteria to have phototherapy ordered after implementing the electronic CDS tool, all (100%) received phototherapy orders, with 14 (93%) placed less than 24 hours and 1 order placed less than 48 hours. The electronic CDS tool identified all eligible patients correctly. The proportion of phototherapy ordered less than 24 hours increased from 70% to 93% after the implementation of the electronic CDS tool. CONCLUSIONS: The electronic CDS tool promoted more appropriate and timely intervention orders to manage critical hyperbilirubinemia in preterm neonates.

Predictors of Early Neurological Deterioration Following Intravenous Thrombolysis: Difference between Risk Factors for Ischemic and Hemorrhagic Worsening.

Background: Prevention of early neurological deterioration (END) is becoming an important therapeutic target in acute ischemic stroke management. The aim of the study is to ascertain the causes and predictors of early neurological deterioration following thrombolysis and determine the predictive value of IScore. Methods: In this single center prospective study, we analyzed clinical, imaging and outcome data in 168 patients thrombolyzed intravenously ≤4.5 hours from onset of stroke. Early neurological deterioration was defined as worsening ≥2 points in the NIHSS score at 24 hours. Results: END occurred in 34 patients (20%) and caused significantly worse short term outcome. Ischemic END (ENDi) (n = 23) was twice as common as symptomatic hemorrhage (ENDh) (n = 11). Ischemia progression (n = 15) was the most common cause. Early malignant edema was another major cause. On multivariate analysis, significant predictors (p <.05) were proximal artery occlusion [all END (p <.001), ENDi and ENDh], previous ischemic insults (all END) and raised diastolic blood pressure (ENDh). ENDi was more common in those with carotid artery occlusion, large vessel disease and previous ischemic insults. ENDh was more common in those with raised diastolic blood pressure and NIHSS-ASPECTS mismatch. For patients with NIHSS <14, IScore >105 and for NIHSS ≥14, IScore >175 was associated with higher risk of END. Conclusion: END occurs in one fifth of patients after intravenous thrombolysis; ENDi outnumbers ENDh. Proximal artery occlusion is a major predictor for END. Potentially modifiable risk factors include admission hyperglycemia and elevated blood pressures. Distinct factors characterize ENDh and ENDi and can guide prevention and management strategies. IScore identifies patients at risk for END.

Compassionate extubation protocol to improve team communication and support in the neonatal intensive care unit.

OBJECTIVE: Compassionate extubation (CE) can be stressful for staff and families in the neonatal intensive care unit (NICU). Our quality improvement initiative developed and implemented a novel symptom management and family support checklist and post-debriefing template to improve team communication and staff support. STUDY DESIGN: An interprofessional team performed a needs assessment, determined key drivers and intervention steps, and implemented changes using Plan-Do-Study-Act cycles. Outcomes included nursing perception of good communication with the medical team, nursing assessment of patient comfort after CE, and frequency of post-event debrief. Outcomes were analyzed using time series design with 12 months baseline data and 6 months post-implementation monitoring. RESULT: Eighteen events were studied. Respondents endorsing "good" communication with the medical team increased by 60%, and debrief participation rate improved by 96%. CONCLUSION: Implementation of a CE checklist and post-event debriefing sheet was associated with increased rate of debriefs and improved team communication.

The Adverse Impact of Unplanned Extubation in a Cohort of Critically Ill Neonates.

BACKGROUND: We sought to describe adverse events associated with unplanned extubation (UE) and to explore risk factors for serious adverse events post-UE among infants who experienced UE. METHODS: Data were prospectively collected on all infants who had a UE event at a single institution over a 4-y period. Demographic information and information on outcomes were obtained retrospectively. We described the frequency of post-UE adverse events: success or failure of extubation trial if offered, rate of re-intubation, post-UE changes in ventilator settings, and serious adverse events post-UE (eg, need for cardiopulmonary resuscitation, clinical sepsis, and death or tracheostomy prior to discharge). We used a multivariate logistic regression model to identify the risk factors associated with serious adverse events. RESULTS: There were 134 documented UE events. Agitation was the most common known cause. After UE, 49% of the subjects were given a trial of extubation, and 65% of the trials were successful at 48 h. Cardiopulmonary resuscitation (CPR) was performed in 13% of cases. In subjects requiring immediate re-intubation, mean airway pressure (̄Paw) and oxygen requirement increased in 33% and 55% of the subjects, respectively. Post-UE clinical sepsis occurred in 17% of subjects. Higher pre-UE ̄Paw and difficult re-intubation were associated with a need for CPR. Subjects who received CPR had increased odds (3.7×) of developing clinical sepsis. CONCLUSION: UE can result in serious adverse events, including hemodynamic instability and possibly an increased risk for clinical sepsis. Difficult re-intubation was associated with a higher risk of needing CPR and, later, tracheostomy and death.

Infant with Clinical Evidence of Pulmonary Hypoplasia: A Case Report.

Pulmonary hypoplasia is the incomplete development of lung tissue. A reduced number of lung cells, airways, and alveoli is the hallmark and can be seen unilaterally or in both lungs. The diagnosis, however, is usually made upon pathologic examination. Here we have presented a case of a term infant presenting with severe hypoxemic respiratory failure. Despite optimizing medical and respiratory management, the infant passed away at 22 hours of life. On autopsy, she was discovered to have bilateral diaphragmatic eventrations, which is a rare cause of secondary pulmonary hypoplasia. She also was found to have some other minor abnormalities on autopsy but no unifying cause for the eventrations and other abnormalities was elucidated.

Video Laryngoscopy vs. Direct Laryngoscopy in Teaching Neonatal Endotracheal Intubation: A Simulation-Based Study.

BACKGROUND: Neonatal endotracheal intubation is a life-saving procedural skill where best practices have been developed from expert opinion. Few empirical studies have examined how this skill should be taught. OBJECTIVE: To determine whether a video laryngoscope (VL) assisted intubation training curriculum compared to a traditional direct laryngoscope (DL) assisted curriculum improves neonatal intubation performance of novice intubators in a simulated setting. METHODS: A randomized trial of novice intubators was conducted at the University of Texas-Houston from 6/2013-8/2013. Eligible candidates were randomly assigned to control group (DL curriculum) or intervention group (VL curriculum). Those in the intervention group received instruction with VL videos and practice with Storz C-MAC® VL (Karl Storz, Tuttlingen, Germany) in addition to a traditional curriculum. Intubation performance was evaluated in a simulated setting using a SimNewB® (Laerdal, NY, USA) manikin and traditional intubation equipment. The number of intubation attempts, outcome of each attempt, and time to successful intubation were recorded. The data was analyzed using Fisher's exact test and logistic regression where appropriate. RESULTS: One hundred twenty-three trainees were enrolled, 62 (50%) in DL group and 61 (50%) in the VL group. Intubation success on first attempt was achieved by 69% (43/62) of the DL group vs. 61% (37/61) of the VL group, P=0.35. Time to successful intubation was 25 sec (interquartile range (IQR) 18, 32) in the DL group and 26.5 sec (IQR 20, 43) in the VL group, P=0.27. Those in the VL group were more likely to need more than two attempts to achieve intubation success, OR=3.09 (95% CI 1.03-9.28). CONCLUSIONS: In a simulated setting, teaching with a VL curriculum did not improve intubation performance compared to teaching with DL. Further studies are needed to determine if VL-based teaching has an impact on clinical intubation performance.
