Male intake of omega-3 fatty acids and risk of intimate partner violence perpetration: a nationwide birth cohort - the Japan Environment and Children's Study

AIMS

Intake of omega-3 polyunsaturated fatty acids (PUFAs) has favourable effects on reducing aggressive and violent behaviours, but its association with perpetration of intimate partner violence (IPV) is not known. We aimed to determine the association between male intake of omega-3 PUFAs and risk of IPV perpetration.

METHODS

Participants were male-female pairs in the Japan Environment and Children's Study, in which first pregnant women and then their partners were enrolled (analytic sample: n = 48 065). Male intake of omega-3 PUFAs during the past year (preconception to mid/late pregnancy) was determined using a food frequency questionnaire. IPV (physical violence and emotional abuse) during pregnancy was measured using a self-reported questionnaire completed by pregnant women in mid/late pregnancy. Generalised additive mixed-model analysis was used to examine the non-linear association between energy-adjusted male omega-3 PUFA intake and the adjusted prevalence of male IPV perpetration.

RESULTS

A sharply decreasing regression curve was plotted for physical violence, with prevalence starting at 1.35% at the lowest intake level and decreasing to a minimum value of 0.76% at intake of 2.20 g/day (71.7th percentile). However, prevalence largely remained flat from there onward, with the upper limit of the error range not reaching the initial lower limit of the error range until intake exceeded 5.21 g/day (99.77th percentile). For emotional abuse, on the other hand, there was a distorted U- or V-shaped regression curve that rose slightly after reaching a minimum. The prevalence declined from 17.69% initially, reached a minimum at 12.44% at 2.13 g/day (68.3th percentile), and then rose slightly. The lower limit of the error range reached the minimum upper limit at 4.17 g/day (99.1th percentile), and the upper limit finally reached the maximum lower limit value at 4.56 g/day (99.5th percentile).

CONCLUSIONS

In this nationwide birth cohort study, higher male intake of omega-3 PUFAs was associated with lower risk of physical violence and emotional abuse perpetration except for extremely high intake. Our results indicate the potential applicability of omega-3 PUFAs in reducing aggressive and violent behaviours in IPV.Trial registration: UMIN000030786.

Workplace Violence Training Programs for Nursing Students: A Literature Review

BACKGROUND

Workplace violence (WPV) is a serious phenomenon affecting nurses in clinical settings around the globe. Like nurses, nursing students are at risk of encountering incidents of WPV, which may lead to negative consequences. WPV training programs are useful in helping nurses and nursing students prevent and manage incidents of WPV. Despite this evidence, the development and implementation of WPV training programs for nursing students pursuing their nursing training in university settings are scarce.

AIMS

The purpose of this literature review was to identify and synthesize the evidence about new training programs on prevention and management of WPV implemented exclusively for undergraduate and graduate nursing students published during the years 2012 to 2018.

METHOD

The literature review utilized five major databases to identify relevant articles containing WPV training programs implemented in university settings to train undergraduate and graduate nursing students. Appraisal of the evidence was conducted using the Mixed Methods Appraisal Tool.

RESULTS

Nine articles included WPV training programs imparted to nursing students in university settings. Overall, nursing students increased their knowledge about WPV and learned practical skills that could be helpful in preventing and managing WPV incidents. WPV training programs were positively accepted by nursing students.

CONCLUSIONS

WPV training programs for nursing students should be mandated in all nursing schools. These trainings are vital in equipping them with proper knowledge and practical skills that could be used to prevent and manage incidents of WPV.

Decreasing Duration of Mechanical Restraint Episodes by Increasing Registered Nurse Assessment and Surveillance in an Acute Psychiatric Hospital[Formula: see text]

INTRODUCTION: The application of mechanical restraints is a high-risk emergency measure that requires psychiatric intensive care to assure patient safety and expedite release at the earliest opportunity. While current Centers for Medicare & Medicaid Services regulations require trained staff to continuously observe restrained individuals, assessment by a registered nurse is required only once an hour. The experience of an acute psychiatric hospital demonstrates that more frequent registered nurse assessments can decrease duration of mechanical restraint episodes. AIMS: The aim of this three-part quality improvement project was to decrease duration of mechanical restraint episodes by increasing the frequency of registered nurse assessment and surveillance. METHODS: First, the requirement for frequency of face-to-face registered nurse assessment during episodes of mechanical restraint was increased from once every hour to once every 30 minutes. Second, the frequency of assessment was increased on half the hospital's units, from every 30 minutes to continuous registered nurse presence during restraint. Finally, the remaining units adopted 1:1 registered nurses during restraint. Mean hours of restraint per episode were measured and compared before and after each practice change. RESULTS: Mean duration of restraint episodes decreased 23% in the first change cycle, 12% in the second, and 44% in the third. Overall, there was a statistically significant 30% decrease in mean duration of restraint episodes. CONCLUSIONS: Increased frequency of registered nurse assessment and surveillance can significantly decrease duration of mechanical restraint episodes. Nurses are encouraged to adopt mechanical restraint practice standards that provide continuous psychiatric intensive care by a registered nurse.

Implementation of the Brøset Violence Checklist on an Acute Psychiatric Unit

BACKGROUND: Violence on inpatient psychiatric settings has significant consequences for patients and staff. Research is needed to determine if Brøset Violence Checklist (BVC) is an accurate predictor of violence. AIMS: The study aims were to determine the relationship between BVC scores and incidence of violent behavior within 24 hours, to compare scores among those requiring high-level nursing interventions for violence, and to investigate the impact of scores on length of stay (LOS) and 30 day-readmission rates. METHOD: Retrospective cohort study. RESULTS: Logistic regression indicates 3.4 times greater risk of violence for every additional point on admission BVC (odds ratio = 3.4, 95% confidence interval = [2.29, 5.08], p < .0001). Patients requiring high-level interventions for violence had higher mean BVC scores on both Day 1 and 2 of admission. Pearson correlation was significant for positive association between BVC on admission and LOS (p < .001). Findings did not establish a link between BVC scores and violence with 30-day readmission rates. CONCLUSIONS: Efforts toward early identification and management of agitation and disruptive behavior is encouraged. Results showed increased risk of violence with every additional point on BVC on admission; further attention should be paid to these patients on admission when using violence screening tools.

Factors associated with use of psychiatric intensive care and seclusion in adult inpatient mental health services

AIMS

Within acute psychiatric inpatient services, patients exhibiting severely disturbed behaviour can be transferred to a psychiatric intensive care unit (PICU) and/or secluded in order to manage the risks posed to the patient and others. However, whether specific patient groups are more likely to be subjected to these coercive measures is unclear. Using robust methodological and statistical techniques, we aimed to determine the demographic, clinical and behavioural predictors of both PICU and seclusion.

METHODS

Data were extracted from an anonymised database comprising the electronic medical records of patients within a large South London mental health trust. Two cohorts were derived, (1) a PICU cohort comprising all patients transferred from general adult acute wards to a non-forensic PICU ward between April 2008 and April 2013 (N = 986) and a randomly selected group of patients admitted to general adult wards within this period who were not transferred to PICU (N = 994), and (2) a seclusion cohort comprising all seclusion episodes occurring in non-forensic PICU wards within the study period (N = 990) and a randomly selected group of patients treated in these wards who were not secluded (N = 1032). Demographic and clinical factors (age, sex, ethnicity, diagnosis, admission status and time since admission) and behavioural precursors (potentially relevant behaviours occurring in the 3 days preceding PICU transfer/seclusion or random sample date) were extracted from electronic medical records. Mixed effects, multivariable logistic regression analyses were performed with all variables included as predictors.

RESULTS

PICU cases were significantly more likely to be younger in age, have a diagnosis of bipolar disorder and to be held on a formal section compared with patients who were not transferred to PICU; female sex and longer time since admission were associated with lower odds of transfer. With regard to behavioural precursors, the strongest predictors of PICU transfer were incidents of physical aggression towards others or objects and absconding or attempts to abscond. Secluded patients were also more likely to be younger and legally detained relative to non-secluded patients; however, female sex increased the odds of seclusion. Likelihood of seclusion also decreased with time since admission. Seclusion was significantly associated with a range of behavioural precursors with the strongest associations observed for incidents involving restraint or shouting.

CONCLUSIONS

Whilst recent behaviour is an important determinant, patient age, sex, admission status and time since admission also contribute to risk of PICU transfer and seclusion. Alternative, less coercive strategies must meet the needs of patients with these characteristics.

Co-occurrence of communication disorder and psychiatric disorders in maltreated children and adolescents: relationship with global functioning

OBJECTIVE

To study the co-occurrence of psychiatric disorders (PD) and communication disorders (CD) and their relationship with global functioning in maltreated children and adolescents.

METHODS

The sample comprised 143 maltreated children and adolescents (55.8% male). All underwent clinical communication and psychiatric evaluations, as well as global functioning assessment using the Children's Global Assessment Scale (C-GAS).

RESULTS

Four groups emerged from evaluation: Group 1 (n=7, 4.9%) did not exhibit any disorders; Group 2 (n=26, 18.2%) exhibited PD; Group 3 (n=34, 23.8%) exhibited CD; and Group 4 (n=76, 53.1%) exhibited both PD and CD on evaluation. Significant differences in global functioning scores were found between G1 and G2, G1 and G4, G2 and G4, and G3 and G4, with the highest C-GAS scores found in G1 and the lowest in G4.

CONCLUSION

Rates of PD and CD are high in this maltreated population. The presence of PD has a major impact on C-GAS score, and the simultaneous presence of CD increases the already impaired function of PD. Demonstration of the additive effects of PD and CD on youth functioning suggests that professionals should be alert to the presence of both disorders to better act preventively and therapeutically in a high-risk population.

Aggression Among Psychiatric Inpatients: The Relationship Between Time, Place, Victims, and Severity Ratings

BACKGROUND

The rate of aggressive acts perpetrated by psychiatric inpatients remains a pressing issue. To date, few studies have distinguished between incident severities.

OBJECTIVE

The aims of the current study were to identify rates of inpatient aggression in an inpatient forensic psychiatric facility and describe the severity of the aggression reported for aggressive incidents.

DESIGN

All documented acts of aggression at a 1,500-bed forensic hospital between 2009 and 2013 provided data about the time, location, and victims of aggressive acts. In total, 52,109 unique incidents were analyzed.

RESULTS

The findings showed an increase in violence rates during meal, medication, and shift change times. Patients (n = 3,436, 62%) were victimized more often than staff members (n = 2,103, 38%). Fall and winter months showed more acts of aggression than summer and spring, but there were no mean differences between severity ratings by season. The results showed that the swing shift saw more severe aggressive incidents than the morning or overnight shifts, p = .001, and significantly more serious incidents occurred when there were staff members working over time, p = .050.

CONCLUSIONS

The current study reports some key findings about aggression rates with a very large sample and presents some valuable data regarding the severity of aggressive acts.
