BACKGROUND: Automated infrared pupillometry (AIP) has been shown to be helpful in the setting of aneurysmal subarachnoid hemorrhage and stroke as an indicator of imminent irreversible brain injury. We postulated that the early detection of pupillary dysfunction after light stimulation using AIP may be useful in patients with traumatic brain injury (TBI). METHODS: We performed a retrospective review of the Establishing Normative Data for Pupillometer Assessment in Neuroscience Intensive Care database, a prospectively populated multicenter registry of patients who had AIP measurements taken during their intensive care unit admission. The primary eligibility criterion was a diagnosis of blunt TBI. Ordinal logistic modeling was used to explore the association between anisocoria and daily Glasgow Coma Scale scores and discharge modified Rankin Scale scores from the intensive care unit and from the hospital. RESULTS: Among 118 subjects in the who met inclusion, there were 6187 pupillometer readings. Of these, anisocoria in ambient light was present in 12.8%, and that after light stimulation was present in 9.8%. Anisocoria after light stimulation was associated with worse injury severity (odds ratio [OR], 0.26 [95% confidence interval (CI), 0.14-0.46]), lower discharge Glasgow Coma Scale scores (OR, 0.28 [95% CI, 0.17-0.45]), and lower discharge modified Rankin Scale scores (OR, 0.28 [95% CI, 0.17-0.47]). Anisocoria in ambient light showed a similar but weaker association. CONCLUSION: Anisocoria correlates with injury severity and with patient outcomes after blunt TBI. Anisocoria after light stimulation seems to be a stronger predictor than does anisocoria in ambient light. These findings represent continued efforts to understand pupillary changes in the setting of TBI.

Nurses die by suicide at a higher rate than the general population. Previous studies have observed mental health problems, including substance use, as a prominent antecedent before death. The purpose of this study was to explore the characteristics of nurses who died by suicide documented in the death investigation narratives from the National Violent Death Reporting System from 2003 to 2017 using thematic analysis and natural language processing. One thousand three hundred and fifty-eight subjects met these inclusion criteria. Narratives from 601 subjects were thematically analyzed and 2544 individual narratives were analyzed using natural language processing. The analyses revealed five themes: "mental health treatment," "poor general health and chronic pain," "substance use," "worsening mental health after bereavement," and "repeating a family member's suicide." Mental health/substance use, chronic illness, and chronic pain were seen to coexist in a complex, interdependent manner that appeared to be entangled in the nurses' narratives before death. These findings echo the need for reducing the stigmatization of mental health problems in nursing and removing barriers to help-seeking behaviors as early preventative interventions. Future research is needed to determine if a comprehensive healthcare integration approach to address these entangled problems would reduce suicide vulnerability in nurses and improve their quality of life.

Background Nurses have a higher rate of suicide than the gender-matched general population at baseline. Quantitative data from the Centers for Disease Control and Prevention National Violent Death Reporting System have been previously analyzed to reveal that nurses have more known job-related issues prior to death by suicide. However, no known study has focused on the context of those job-related problems prior to nurse suicide. Purpose The aim of this study was to provide context to job-related problems experienced before nurse death by suicide. Methods Cases were selected either because they were coded as having a job-related problem prior to death or the words "job" or "work" appeared in the case investigation narrative. Natural language processing and thematic analysis of free-text medical examiner and law enforcement investigation narratives were performed to better describe nurse deaths by suicide in cases with known job-related problems prior to death. Results Narratives from a total of 203 nurse deaths from between 2003 and 2017 were included in this study. Very little was reported regarding the actual work of being a nurse. Job-related problems of these 203 deaths focused on substance use, mental health problems, chronic pain, or job loss due to investigations for substance use or diversion of medication. Conclusions Nurses who lose a nursing position or leave the profession because of substance use, mental health issues, or chronic pain are at risk for nurse suicide. Alternative-to-discipline programs for nurses with substance use disorder need to be improved and standardized. Earlier or more complete treatment for mental illness may help prevent suicide in this population.

Aims and objectives To describe the substance use and mental health characteristics of nurses who complete suicide compared to non-nurses. Background Nurses are at higher risk of suicide than the general population. The relationship between substance use, mental health and suicide in a large sample of nurses in the USA has not been previously described. Design Retrospective observational quantitative analysis. Methods Suicide data were retrospectively analysed in the Centers for Disease Control and Prevention National Violent Death Reporting System from 2003 to 2017. Data were compared between nurses who died by suicide (n = 2,306) and non-nurses who died by suicide (n = 185,620) using odds ratios calculations and chi-square test of proportions to detect independent risk factors of suicide completion in nurses. This study followed the STROBE guidelines. Results Significant differences between nurses and non-nurses were found. Among decedents for whom substances were implicated as a cause of death, nurses were far more likely to be positive at the time of death for almost all substance classifications. Both male and female nurses were more likely than non-nurses to have a mental health problem reported. Among both female and male nurses, job problems were more prevalent compared to non-nurses (12.8% and 19.9% versus 7.2% and 11.9%, respectively). Female nurses were more likely to have a physical health problem compared to female non-nurses, male nurses and male non-nurses (26.2% versus 21.3%, 22% and 20.4%). Conclusion Unique relationships between substance use and mental health exist among nurses who complete suicide which may offer specific opportunities for interventions to reduce suicide. Relevance to clinical practice Efforts to address workplace stress, facilitate self-referral for risky substance use, encourage mental health treatment and reduce the stigma associated with seeking help all offer potential interventions to reduce nurse suicide.

BackgroundSuicide is one of the leading causes of death worldwide, and estimates of suicide among health professionals are higher than the general population. High rates of suicide among physicians and nurses have been described previously, but there is a lack of data for suicides completed by pharmacists.ObjectiveThe purpose of this study was to quantify the incidence, means, and characteristics of pharmacist suicides in the United States.MethodsData were obtained from the Centers for Disease Control and Prevention's National Violent Death Reporting System (NVDRS) for the years 2003-2018. The dataset contained all suicides, coded by occupation, reported by medical examiners and law enforcement from 39 states and Washington DC and Puerto Rico. Suicide characteristics were compared between pharmacists and nonpharmacists. Age-adjusted rates were calculated for 2004, 2009, and2014.ResultsDuring 2003-2018, the NVDRS contained 316 pharmacist suicides compared with 213,146 nonpharmacist suicides. The age-adjusted rates per 100,000 people were 19.6, 20.1, and 18.2 for 2004, 2009 and 2014, respectively. The most common means of suicide was firearm. Associated factors for suicide included job problems, current mental illness treatment, and suicide note.ConclusionSuicide rates among pharmacists are higher than the general population. Future research is needed to evaluate the context of job-related problems to mitigate risk. Encouraging help-seeking behaviors to identify and treat pharmacist depression is warranted.

BACKGROUND Automated pupillometry is becoming widely accepted as an objective measure of pupillary function, especially in neurocritical care units. Normative reference values and thresholds to denote a significant change are necessary for integrating automated pupillometry into practice. OBJECTIVE Providing point estimates of normal ranges for pupillometry data will help clinicians intuit meaning from these data that will drive clinical interventions. METHODS This study used a planned descriptive analysis using data from a multicenter registry including automated pupillometry assessments in 2140 subjects from 3 US hospitals collected during a 3-year period. RESULTS We provide a comprehensive list of admission pupillometry data. Our data demonstrate significant differences in pupillary values for Neurological Pupil Index, latency, and constriction velocity when stratified by age, sex, or severity of illness defined by the Glasgow Coma Scale score. CONCLUSION This study provides a greater understanding of expected distributions for automated pupillometry values in a wide range of neurocritical care populations.

Nurses are known to be at an increased risk of death by suicide, and recent studies have found links between nurse suicide, substance use, mental health issues, and job problems. Because of stigma, inaccessibility of resources, and regulatory and legal issues, nurses are unlikely to seek help unless a crisis forces them into treatment. The purpose of this article is to review the current understanding of nurse suicide, the psychological impact of the novel coronavirus (COVID-19) pandemic, the strategic planning approach to identify the needs of nurses, and promising interventions and practices. Evidence-based strategies to intervene at the personal, institutional, and regulatory levels should be employed to reduce nurse suicide by focusing not only on suicide but also on treatment of substance and mental health issues, as well as a renewed focus on disciplinary procedures that may place nurses in immediate danger of death by suicide. Nurse leaders have a moral obligation to provide proactive, meaningful interventions to reduce the risk of death by suicide among nurses.

RESUMO Objetivo: Calcular as velocidades médias da dilatação de pupila para classificar a gravidade da lesão derivada da escala de coma de Glasgow, estratificada por variáveis de confusão. Métodos: Neste estudo, analisaram-se 68.813 exames das pupilas para determinar a velocidade normal de dilatação em 3.595 pacientes com lesão cerebral leve (13 - 15), moderada (9 - 12) ou grave (3 - 8), segundo a escala de coma de Glasgow. As variáveis idade, sexo, raça, tamanho da pupila, tempo de permanência na unidade de terapia intensiva, pressão intracraniana, uso de narcóticos, classificação pela escala de coma de Glasgow e diagnóstico foram consideradas confundidoras e controladas para análise estatística. Empregou-se regressão logística com base em algoritmo de classificação com aprendizado de máquina para identificar os pontos de corte da velocidade de dilatação para as categorias segundo a escala de coma de Glasgow. Resultados: As razões de chance e os intervalos de confiança desses fatores se mostraram estatisticamente significantes em sua influência sobre a velocidade de dilatação. A classificação com base na área sob a curva mostrou que, para o grau leve, na escala de coma de Glasgow, o limite da velocidade de dilatação foi de 1,2mm/s, com taxas de falsa probabilidade de 0,1602 e 0,1902 e áreas sob a curva de 0,8380 e 0,8080, respectivamente, para os olhos esquerdo e direito. Para grau moderado na escala de coma de Glasgow, a velocidade de dilatação foi de 1,1mm/s com taxas de falsa probabilidade de 0,1880 e 0,1940 e áreas sob a curva de 0,8120 e 0,8060, respectivamente, nos olhos esquerdo e direito. Mais ainda, para o grau grave na escala de coma de Glasgow, a velocidade de dilatação foi de 0,9mm/s, com taxas de falsa probabilidade de 0,1980 e 0,2060 e áreas sob a curva de 0,8020 e 0,7940, respectivamente, nos olhos esquerdo e direito. Esses valores foram diferentes dos métodos prévios de descrição subjetiva e das velocidades de dilatação previamente estimadas. Conclusão: Observaram-se velocidades mais lentas de dilatação pupilar em pacientes com escores mais baixos na escala de coma de Glasgow, indicando que diminuição da velocidade pode indicar grau mais grave de lesão neuronal. ABSTRACT Objective: To calculate mean dilation velocities for Glasgow coma scale-derived injury severity classifications stratified by multiple confounding variables. Methods: In this study, we examined 68,813 pupil readings from 3,595 patients to determine normal dilation velocity with brain injury categorized based upon a Glasgow coma scale as mild (13 - 15), moderate (9 - 12), or severe (3 - 8). The variables age, sex, race, pupil size, intensive care unit length of stay, intracranial pressure, use of narcotics, Glasgow coma scale, and diagnosis were considered as confounding and controlled for in statistical analysis. Machine learning classification algorithm-based logistic regression was employed to identify dilation velocity cutoffs for Glasgow coma scale categories. Results: The odds ratios and confidence intervals of these factors were shown to be statistically significant in their influence on dilation velocity. Classification based on the area under the curve showed that for the mild Glasgow coma scale, the dilation velocity threshold value was 1.2mm/s, with false probability rates of 0.1602 and 0.1902 and areas under the curve of 0.8380 and 0.8080 in the left and right eyes, respectively. For the moderate Glasgow coma scale, the dilation velocity was 1.1mm/s, with false probability rates of 0.1880 and 0.1940 and areas under the curve of 0.8120 and 0.8060 in the left and right eyes, respectively. Furthermore, for the severe Glasgow coma scale, the dilation velocity was 0.9mm/s, with false probability rates of 0.1980 and 0.2060 and areas under the curve of 0.8020 and 0.7940 in the left and right eyes, respectively. These values were different from the previous method of subjective description and from previously estimated normal dilation velocities. Conclusion: Slower dilation velocities were observed in patients with lower Glasgow coma scores, indicating that decreasing velocities may indicate a higher degree of neuronal injury.

Background The Glasgow Coma Scale was developed in 1974 as an injury severity score to assess and predict outcome after traumatic brain injury. The tool is now used to score depth of impaired consciousness in patients with and without traumatic brain injury. However, evidence supporting the use of the Glasgow Coma Scale in the latter group is limited. Objective To assess Glasgow Coma Scale score on hospital admission as a predictor of outcome in patients without traumatic brain injury. Methods This was a secondary analysis of prospectively collected data from 3507 patients admitted to 4 hospitals between October 2015 and October 2019. Patients with a primary diagnosis of traumatic brain injury were excluded from this study. Results The mean age of the 3507 participants in the study was 57 years. Participants were primarily female (52%), White (77%), and non-Hispanic (89%). On admission, 90% of patients had a modified Rankin Scale score of 0 to 3 and 72% had a Glasgow Coma Scale score of 13 to 15 (mild injury). Generalized estimating equation modeling indicated that admission Glasgow Coma Scale score did not predict modified Rankin Scale score at discharge in patients not diagnosed with traumatic brain injury (Glasgow Coma Scale score Conclusions The Glasgow Coma Scale is not recommended for use in patients without traumatic brain injury; clinicians should use a more appropriate and validated clinical assessment instrument for this patient population.
