Observational Study
Automated False Alarm Reduction in a Real-Life Intensive Care Setting Using Motion Detection.
Contemporary monitoring systems are sensitive to motion artifacts and cause an excess of false alarms. This results in alarm fatigue and hazardous alarm desensitization. To reduce the number of false alarms, we developed and validated a novel algorithm to classify alarms, based on automatic motion detection in videos. ⋯ The proposed system is a step forward toward alarm reduction; however, implementation of additional layers, such as signal curve analysis, multiple parameter correlation analysis and/or more sophisticated video-based analytics are needed for improvement.

To report a consensus on the different competency levels for the elaboration of skill recommendations in performing brain ultrasonography within the neurocritical care setting. ⋯ Results from this consensus permitted stratification of the different ultrasound examination skills in four levels with progressively increasing competences. This consensus can be useful as a guide for beginners in brain ultrasonography and for the development of specific training programs within this field.

Informal caregivers (e.g., family and friends) are at risk for developing depression, which can be detrimental to both caregiver and patient functioning. Initial evidence suggests that resiliency may reduce the risk of depression. However, gender differences in associations between multiple psychosocial resiliency factors and depression have not been examined among neuroscience intensive care unit (neuro-ICU) caregivers. We explored interactions between caregiver gender and baseline resiliency factors on depression symptom severity at baseline through 3 and 6 months post-discharge. ⋯ Results support implementation of psychosocial resiliency interventions for caregivers of patients admitted to the neuro-ICU early in the recovery process. Male caregivers may particularly benefit from strategies focused on increasing intimate care (e.g., physical and emotional affection with their loved one) and quality of the patient-caregiver dyadic relationship.

Observational Study
A Pilot Study of Pharyngeal Electrical Stimulation for Orally Intubated ICU Patients with Dysphagia.
Dysphagia is a common disorder in neurological and non-neurological intensive care unit (ICU) patients and can lead to aspiration pneumonia, prolonged ventilation, and delayed extubation. Dysphagia is an independent predictor of increased mortality. In dysphagic stroke patients with tracheotomy, the use of pharyngeal electric stimulation (PES), an emerging technique to treat dysphagia, has been shown to improve airway protection and shorten time to decannulation. The objective of this study was to determine whether patients who receive PES have a lower prevalence of pneumonia and frequency of reintubation. ⋯ Although limited by its small size and non-blinded design, this is the first study demonstrating the benefits of PES in ICU patients still orally intubated, thus offering a potential new method to reduce morbidity, mortality, and economic burden in a mixed ICU population. In order to further investigate and strengthen our findings, a statistically powered, randomized controlled study is recommended.

Glucose control status after cardiac arrest depending on chronic glycemic status and the association between chronic glycemic status and outcome in cardiac arrest survivors are not well known. We investigated the association between glycated hemoglobin (HbA1c) and 6-month neurologic outcome in cardiac arrest survivors undergoing therapeutic hypothermia (TH) and whether mean glucose, area under curve (AUC) of glucose during TH, and neuron-specific enolase (NSE) are different between normal and high HbA1c groups. ⋯ Higher HbA1c was independently associated with unfavorable neurologic outcome. Glycemic status during TH was different between normal and high HbA1c groups.
