Nurses’ contribution to prevent seclusion in acute mental health care

BACKGROUND Seclusion is an intervention widely used in Dutch mental health care. The intervention can be effective in acute situations to avert (further) aggression or self-harm. However, seclusion is also a controversial intervention that may not have any positive effect with regard to symptom improvement. In general patients report negative effects after being secluded e.g. anxiety and having had a traumatic experience.The main reason for seclusion is not manageable aggressive behaviour of a patient. Earlier studies reported several risk factors that may contribute to seclusion, regarding patients’ characteristics, but also with regard to staff characteristics, working protocols and unit characteristics. Because of unequivocally results there is the need for a longitudinal prospective study to examine staff- and unit determinants in association with seclusion.AIMS The objective of this study is to determine which nursing staff and unit characteristics are associated with seclusion following aggression in hospitalized adult psychiatric patients. We hope to create a predictive model to estimate the risk of seclusion on an acute psychiatric ward.METHODS We will conduct a prospective observational study on a closed psychiatric ward of an academic hospital. Patients are aged 18 – 65 years and are admitted when their psychiatric condition leads to an immediate threat to the patient themselves or their surroundings.All nurses on the ward are all qualified nurses and registered in the Dutch registration of healthcare professionals. They are trained every six months in techniques of verbal de-escalation and safe physical restraint. For both nurses and the patients baseline characteristics are monitored. Every shift (day, evening, night) data are gathered on the patients, nurses and unit. Data are retrieved from the electronic patient chart, including information of the Brøset Violence Checklist. Furthermore, the exchange of information among nurses is measured using the Grid instrument. Data will be analysed using multilevel regression analysis. Data will be collected for a period of 2 years, which started January 2013.RESULTS The primary endpoint in our study is the incidence of seclusion. As a secondary endpoint, the duration of the seclusion is measured. These endpoints are measured using the Argus registration system and will be linked to predictors of seclusion, with special focus on the nursing staff- and unit determinants.

The effects of the COVID‑19 lockdowns on motor skill development of 6‑ and 7‑year old children in the Netherlands: a longitudinal study

BackgroundThe closing of schools and sports clubs during the COVID-19 lockdown raised questions about the possible impact on children’s motor skill development. Therefore, we compared motor skill development over a one-year period among four different cohorts of primary school children of which two experienced no lockdowns during the study period (control cohorts) and two cohorts experienced one or two lockdowns during the study period (lockdown cohorts).MethodsA total of 992 children from 9 primary schools in Amsterdam (the Netherlands) participated in this study (age 5 – 7; 47.5% boys, 52.5% girls). Their motor skill competence was assessed twice, first in grade 3 (T1) and thereafter in grade 4 (T2). Children in control group 1 and lockdown group 1 were assessed a third time after two years (T3). Motor skill competence was assessed using the 4-Skills Test, which includes 4 components of motor skill: jumping force (locomotion), jumping coordination (coordination), bouncing ball (object control) and standing still (stability). Mixed factorial ANOVA’s were used to analyse our data.ResultsNo significant differences in motor skill development over the study period between the lockdown groups and control groups (p > 0.05) were found, but a difference was found between the two lockdown groups: lockdown group 2 developed significantly better than lockdown group 1 (p = 0.008). While socioeconomic status was an effect modifier, sex and motor ability did not modify the effects of the lockdowns.ConclusionsThe COVID-19 lockdowns in the Netherlands did not negatively affect motor skill development of young children in our study. Due to the complexity of the factors related to the pandemic lockdowns and the dynamic systems involved in motor skill development of children, caution must be taken with drawing general conclusions. Therefore, children’s motor skill development should be closely monitored in the upcoming years and attention should be paid to individual differences.

The effect of small-sided game formats on physical and technical performance in wheelchair basketball

Purpose: To examine the effects of different small-sided games (SSGs) on physical and technical aspects of performance in wheelchair basketball (WB) players. Design: Observational cohort study. Methods: Fifteen highly trained WB players participated in a single 5v5 (24-s shot clock) match and three 3v3 SSGs (18-s shot clock) on a (1) full court, (2) half-court, and (3) modified-length court. During all formats, players’ activity profiles were monitored using an indoor tracking system and inertial measurement units. Physiological responses were monitored via heart rate and rating of perceived exertion. Technical performance, that is, ball handling, was monitored using video analysis. Repeated-measures analysis of variance and effect sizes (ESs) were calculated to determine the statistical significance and magnitude of any differences between game formats. Results: Players covered less distance and reached lower peak speeds during half-court (P ≤ .0005; ES ≥ very large) compared with all other formats. Greater distances were covered, and more time was spent performing moderate- and high-speed activity (P ≤ .008; ES ≥ moderate) during full court compared with all other formats. Game format had little bearing on physiological responses, and the only differences in technical performance observed were in relation to 5v5. Players spent more time in possession, took more shots, and performed more rebounds in all 3v3 formats compared with 5v5 (P ≤ .028; ES ≥ moderate). Conclusions: Court dimensions affect the activity profiles of WB players during 3v3 SSGs yet had little bearing on technical performance when time pressures (shot clocks) were constant. These findings have important implications for coaches to understand which SSG format may be most suitable for physically and technically preparing WB players.

FRP versus traditional strengthening on a typical mid-rise Turkish RC building

This paper investigates the limits and efficacies of the Fiber Reinforced Polymer (FRP) material for strengthening mid-rise RC buildings against seismic actions. Turkey, the region of the highest seismic risk in Europe, is chosen as the case-study country, the building stock of which consists in its vast majority of mid-rise RC residential and/or commercial buildings. Strengthening with traditional methods is usually applied in most projects, as ordinary construction materials and no specialized workmanship are required. However, in cases of tight time constraints, architectural limitations, durability issues or higher demand for ductile performance, FRP material is often opted for since the most recent Turkish Earthquake Code allows engineers to employ this advanced-technology product to overcome issues of inadequate ductility or shear capacity of existing RC buildings. The paper compares strengthening of a characteristically typical mid-rise Turkish RC building by two methods, i.e., traditional column jacketing and FRP strengthening, evaluating their effectiveness with respect to the requirements of the Turkish Earthquake Code. The effect of FRP confinement is explicitly taken into account in the numerical model, unlike the common procedure followed according to which the demand on un-strengthened members is established and then mere section analyses are employed to meet the additional demands.
