Ensuring implementation success : how should coach injury prevention education be improved if we want coaches to deliver safety programmes during training sessions?

Coaches play a major role in encouraging and ensuring that participants of their teams adopt appropriate safety practices. However, the extent to which the coaches undertake this role will depend upon their attitudes about injury prevention, their perceptions of what the other coaches usually do and their own beliefs about how much control they have in delivering such programmes. Fifty-one junior netball coaches were surveyed about incorporating the teaching of correct (safe) landing technique during their delivery of training sessions to junior players. Overall, >94% of coaches had strongly positive attitudes towards teaching correct landing technique and >80% had strongly positive perceptions of their own control over delivering such programmes. Coaches’ ratings of social norms relating to what others think about teaching safe landing were more positive (>94%) than those relating to what others actually do (63–74%). In conclusion, the junior coaches were generally receptive towards delivering safe landing training programmes in the training sessions they led. Future coach education could include role modelling by prominent coaches so that more community-level coaches are aware that this is a behaviour that many coaches can, and do, engage in.

Modelling skill acquisition in acquired brain injury

Acquired brain injury (ABI) is a debilitating condition often requiring extensive rehabilitation. Although cognitive rehabilitation is concerned with overcoming a skills deficit, the application of skill acquisition research in this context has been non-existent. Examining post-injury learning in terms of the qualitative variables associated with different phases of skill acquisition is likely to be beneficial in assessing patient status and monitoring progress, as well as identifying changing needs over the course of learning. However, current models of skill acquisition overlook the potential impact of variables such as emotion, implicit learning, metacognition, motivation, and strategies that can be leveraged to improve skill acquisition. The current paper attempts to lay the groundwork for modelling and improving skill acquisition in ABI.

High volume versus low volume balance training on postural sway in adults with previous ankle inversion injury

Balance training is commonly used in the rehabilitation process of ankle injuries; however, the exercise prescription guidelines for prescribing balance training are poorly understood. The aim of the present study was to determine if high or low volume balance training is more effective in improving postural sway after an 8 week balance training program utilising the same exercises. Seventeen subjects (14 male, 3 female) with a mean age of 24.06 ± 5.6 years were randomly allocated into a control group (CG), low volume training (LVT) or high volume training (HVT). All subjects had sustained at least two inversion ankle injuries within the last 18 months. Subjects completed 8 weeks of balance training of up to 30 mins duration, 3 times per week. LVT consisted of 40 repetitions for week 1, progressing to 90 repetitions by week 8. HVT consisted of 60 repetitions for week 1, progressing to 130 repetitions by week 8. The maximum centre of pressure (COP) excursion was obtained from the porce plate in the medial-lateral (ML) direction and subsequently used for pre-test and post-test analysis. After the 8 week training intervention, there was a significant (P<0.001) difference in postural sway between pre and post testing for both the LVT (pre = 88.69mm ± 25.08mm, post = 72.17mm ± 27.53mm) and HVT (pre = 77.47mm ±10.57mm, post = 58.54mm ± 7.01mm) groups. There was no significant (P>0.01) difference detected for improvements between the LVT and HVT, however reported effect sizes (ES) showed large effect size chances in the high volume training (ES = 1.7) whereas low volume training showed medium effect sizes changes (ES = 0.6). This preliminary study demonstrates the importance of training volume in the rehabilitation of ankle injuries, with the HVT being superior to LVT.

Exploring known risk factors for pressure injury with visual technology

This research has identified that the use of visual technology can support the correlation between peak interface pressure and pressure gradients in the understanding of deep tissue injury. In addition as a pilot study the visual assessment of buttock shape has demonstrated potential for identifying risk of ischial or sacral pressure injury.

Creatine pretreatment prevents birth asphyxia–induced injury of the newborn spiny mouse kidney

Background:
Acute kidney injury (AKI) is a major complication for infants following an asphyxic insult at birth. We aimed to determine if kidney structure and function were affected in an animal model of birth asphyxia and if maternal dietary creatine supplementation could provide an energy reserve to the fetal kidney, maintaining cellular respiration during asphyxia and preventing AKI.

Methods:
Pregnant spiny mice were maintained on normal chow or chow supplemented with creatine from day 20 gestation. On day 38 (term ~39 d), pups were delivered by cesarean section (c-section) or subjected to intrauterine asphyxia. Twenty-four hours after insult, kidneys were collected for histological or molecular analysis. Urine and plasma were also collected for biochemical analysis.

Results:
AKI was evident at 24 h after birth asphyxia, with a higher incidence of shrunken glomeruli (P < 0.02), disturbance to tubular arrangement, tubular dilatation, a twofold increase (P < 0.02) in expression of Ngal (early marker of kidney injury), and decreased expression of the podocyte differentiation marker nephrin. Maternal creatine supplementation prevented the glomerular and tubular abnormalities observed in the kidney at 24 h and the increased expression of Ngal.

Conclusion:
Maternal creatine supplementation may prove useful in ameliorating kidney injury associated with birth asphyxia.

Thai emergency nurses’ management of patients with severe traumatic brain injury: comparison of knowledge and clinical management with best available evidence

Background:
In Thailand, the rate of TBI-related hospitalisation is increasing, however, little is known about the evidence-based management of severe TBI in the developing world. The aim of this study was to explore Thai emergency nurses’ management of patients with severe TBI.

Methods:
An exploratory descriptive mixed method design was used to conduct this two stage study: survey methods were used to examine emergency nurses’ knowledge regarding management of patients with severe TBI (Stage 1) and observational methods were used to examine emergency nurses’ clinical management of patients with severe TBI (Stage 2). The study setting was the emergency department (ED) at a regional hospital in Southern Thailand.

Results:
34 nurses participated in Stage 1 (response rate 91.9%) and the number of correct responses ranged from 33.3% to 95.2%. In Stage 2, a total of 160 points of measurement were observed in 20 patients with severe TBI over 40 h. In this study there were five major areas identified for the improvement of care of patients with severe TBI: (i) end-tidal carbon dioxide (ETCO2) monitoring and targets; (ii) use of analgesia and sedation; (iii) patient positioning; (iv) frequency of nursing assessment; and (v) dose of Mannitol diuretic.

Conclusions:
There is variation in Thai nurses’ knowledge and care practices for patients with severe TBI. To increase consistency of evidence-based TBI care in the Thai context, a knowledge translation intervention that is ecologically valid, appropriate to the Thai healthcare context and acceptable to the multidisciplinary care team is needed.

Changes in injury-related hospital emergency department presentations associated with the imposition of regulatory versus voluntary licensing conditions on licensed venues in two cities

Introduction and Aims
Regulatory and collaborative intervention strategies have been developed to reduce the harms associated with alcohol consumption on licensed venues around the world, but there remains little research evidence regarding their comparative effectiveness. This paper describes concurrent changes in the number of night-time injury-related hospital emergency department presentations in two cities that implemented either a collaborative voluntary approach to reducing harms associated with licensed premises (Geelong) or a regulatory approach (Newcastle).

Design and Methods
This paper reports findings from Dealing with Alcohol-Related problems in the Night-Time Economy project. Data were drawn from injury-specific International Classification of Disease, 10th Revision codes for injuries (S and T codes) presenting during high-alcohol risk times (midnight—5.59 am, Saturday and Sunday mornings) at the emergency departments in Geelong Hospital and Newcastle (John Hunter Hospital and the Calvary Mater Hospital), before and after the introduction of licensing conditions between the years of 2005 and 2011. Time-series, seasonal autoregressive integrated moving average analyses were conducted on the data obtained from patients' medical records.

Results
Significant reductions in injury-related presentations during high-alcohol risk times were found for Newcastle since the imposition of regulatory licensing conditions (344 attendances per year, P < 0.001). None of the interventions deployed in Geelong (e.g. identification scanners, police operations, radio networks or closed-circuit television) were associated with reductions in emergency department presentations.

Discussion and Conclusions
The data suggest that mandatory interventions based on trading hours restrictions were associated with reduced emergency department injury presentations in high-alcohol hours than voluntary interventions.
