Impact of hospital security programmes and workplace aggression on nurse perceptions of safety.

AIM: To assess how nurses' perception of their safety and risk of violence was affected by their work environment and whether this perception correlated with their actual risk. BACKGROUND: The work environment has an impact on nurses' perception of their risk of violence and this perception affects worker productivity, quality, employee retention, worker satisfaction and their actual safety. METHODS: A cross-sectional survey was conducted in person of 314 emergency department nurses and 143 psychiatric nurses, and assault data was collected from injury logs. RESULTS: This study found that nurses in the emergency and psychiatric units differed in their perception of violence and safety. The workplace elements that led to a perception of lower risk of violence were not correlated with a lower rate of injury from violent acts. The nurses' beliefs about the adequacy of security equipment, security guards and the frequency of verbal abuse were strongly correlated with perceived safety. CONCLUSION: Several factors that influence nurses' perception of their risk of violence are not well correlated with their actual risk. IMPLICATIONS FOR NURSING MANAGEMENT: Managers must address workplace elements that affect nurse perceptions because this has an impact on quality and employee retention. They must also address factors that have an impact on the actual risk of violence because this study showed, for the first time, that these may differ from perceptions.

Increased incidence of inflicted traumatic brain injury in children after a natural disaster.

BACKGROUND: The incidence of child abuse following natural disasters has not been studied thoroughly. However, parental stress and decreased social support have been linked to increased reports of child maltreatment. We hypothesized that a large-scale natural disaster (North Carolina's Hurricane Floyd) would increase the incidence of inflicted traumatic brain injury (TBI) in young children. METHODS: An ecologic study design was used to compare regions affected to those regions unaffected by the disaster. Cases of inflicted TBI resulting in admission to an intensive care unit or death from September 1998 through December 2001 in North Carolina were ascertained. Poisson regression modeling was employed to calculate rate ratios of injury for each geographic area by time period. RESULTS: Inflicted TBI in the most affected counties increased in the 6 months post-disaster in comparison to the same region pre-disaster (rate ratio 5.1, 95% confidence interval [CI]=1.3-20.4), as did non-inflicted TBI (rate ratio 10.7, 95% CI=2.0-59.4). No corresponding increased incidence was observed in counties less affected or unaffected by the disaster. The rate of inflicted injuries returned to baseline in the severely affected counties 6 months post-hurricane; however, the rate of non-inflicted injuries appeared to remain elevated for the entire post-hurricane study period. CONCLUSIONS: Families are vulnerable to an elevated risk of inflicted and non-inflicted child TBI following a disaster. This information may be useful in future disaster planning.

A population-based study of inflicted traumatic brain injury in young children.

CONTEXT: Physical abuse is a leading cause of serious head injury and death in children aged 2 years or younger. The incidence of inflicted traumatic brain injury (TBI) in US children is unknown. OBJECTIVE: To determine the incidence of serious or fatal inflicted TBI in a defined US population of approximately 230 000 children aged 2 years or younger. DESIGN, SETTING, AND SUBJECTS: All North Carolina children aged 2 years or younger who were admitted to a pediatric intensive care unit or who died with a TBI in 2000 and 2001 were identified prospectively. Injuries were considered inflicted if accompanied by a confession or a medical and social service agency determination of abuse. MAIN OUTCOME MEASURE: Incidence of inflicted TBI. Multivariate logistic regression models were used to compare children with inflicted injuries with those with noninflicted injuries and with the general state population aged 2 years or younger. RESULTS: A total of 152 cases of serious or fatal TBI were identified, with 80 (53%) incurring inflicted TBI. The incidence of inflicted traumatic brain injury in the first 2 years of life was 17.0 (95% confidence interval [CI], 13.3-20.7) per 100 000 person-years. Infants had a higher incidence than children in the second year of life (29.7 [95% CI, 22.9-36.7] vs 3.8 [95% CI, 1.3-6.4] per 100 000 person-years). Boys had a higher incidence than girls (21.0 [95% CI, 15.1-26.6] vs 13.0 [95% CI, 8.4-17.7] per 100 000 person-years). Relative to the general population, children who incurred an increased risk of inflicted injury were born to young mothers (< or =21 years), non-European American, or products of multiple births. CONCLUSIONS: In this population of North Carolina children, the incidence of inflicted TBI varied by characteristics of the injured children and their mothers. These data may be helpful for informing preventive interventions.

A population-based comparison of clinical and outcome characteristics of young children with serious inflicted and noninflicted traumatic brain injury.

OBJECTIVE: Diagnosing inflicted traumatic brain injury (TBI) in young children is difficult in practice. Comparisons of children with inflicted and noninflicted TBI may help to identify markers of inflicted TBI. The objective of this study was to compare inflicted and noninflicted TBI in terms of presenting complaints, clinical features, and hospital outcomes. METHODS: The presenting complaint, clinical finding, hospital course, and outcome of all children who were aged 2 years or younger in North Carolina and were admitted to a pediatric intensive care unit or died with a TBI in 2000 and 2001 were reviewed. Clinical presentation and injury types were compared between children with inflicted and noninflicted TBI. Risk ratios were used to compare clinical and outcome characteristics between the 2 groups. Among survivors, multivariate binomial regression was used to examine the adjusted risk of a poor outcome dependent on injury type. RESULTS: A total of 80 (52.6%) children had inflicted and 72 (47.3%) children had noninflicted TBI. Children with noninflicted TBI (not in a motor vehicle crash) were more likely to present to the emergency department asymptomatic (44.8% vs 8.3%) and to have a specific history of trauma than children with inflicted TBI. Retinal hemorrhage, metaphyseal fracture, rib fracture, and subdural hemorrhage were more commonly found in children with inflicted compared with noninflicted TBI. Skeletal survey and ophthalmologic examination combined would have missed 8 (10.0%) inflicted TBI cases. CONCLUSIONS: Manner of presentation and injury types are helpful in distinguishing inflicted TBI. Clinicians should not rule out inflicted TBI on the basis of skeletal survey and ophthalmoscopy alone but should proceed to computed tomography and/or magnetic resonance imaging.
