Initial emergency nursing management of patients with severe traumatic brain injury : development of an evidence-based care bundle for the Thai emergency department context.

Thai emergency nurses play a vital role in caring for patients with severe TBI, and are an important part of the healthcare team throughout the resuscitation phase. They are also responsible for continuous physiological monitoring, and detecting deterioration associated with increased intracranial pressure and preventing secondary brain injury. However, there is known variation in Thai nurses' knowledge and care practices for patients with severe TBI. In addition, there are no specific evidence-based practice guidelines available for emergency nursing management of patients with severe TBI.

A cross-sectional examination of non-suicidal self-injury, disordered eating, impulsivity, and compulsivity in a sample of adult women

Non-suicidal self-injury has been classed as having both impulsive and compulsive characteristics (Simeon & Favazza, 2001). These constructs have been related to disordered eating behaviors such as vomiting (Favaro & Santonastaso, 1998). Utilizing an international sample of adult females, this paper further explored this model, aiming to identify whether all types of disordered eating could be classified as impulsive or compulsive, and whether the impulsive and compulsive groupings reflect underlying trait impulsivity and compulsivity. The hypothesized impulsive and compulsive dimensions did not emerge from the data. Notably however, all self-injurious and disordered eating behaviors were linked to Urgency (an impulsivity facet) to varying degrees; no relationship with trait compulsivity was found. These findings are discussed, study limitations are noted, and relevance for clinical practice is outlined.

Biomechanical studies: science (f)or common sense?

 Introduction: It is our impression that many biomechanical studies invest substantial resources studying the obvious: that more and larger metal is stronger. The purpose of this study is to evaluate if a subset of biomechanical studies comparing fixation constructs just document common sense. Methods: Using a web-based survey, 274 orthopaedic surgeons and 81 medical students predicted the results of 11 biomechanical studies comparing fracture fixation constructs (selected based on the authors' sense that the answer was obvious prior to performing the study). Sensitivity, specificity, and accuracy were calculated according to standard formulas. The agreement among the observers was calculated by using a multirater kappa, described by Siegel and Castellan. Results: The accuracy of predicting outcomes was 80% or greater for 10 of 11 studies. Accuracy was not influenced by level of experience (i.e., time in practice and medical students vs. surgeons). There were substantial differences in accuracy between observers from different regions. The overall categorical rating of inter-observer reliability according to Landis and Koch was moderate (k = 0.55; standard error (SE) = 0.01). Conclusion: The results of a subset of biomechanical studies comparing fracture fixation constructs can be predicted prior to doing the study. As these studies are time and resource intensive, one criterion for proceeding with a biomechanical study should be that the answer is not simply a matter of common sense. © 2014 Elsevier Ltd.

Attributions of responsibility for motor vehicle accidents and post-injury outcomes.

 This thesis explored the relationship between attributions of responsibility for motor vehicle accidents and post-injury outcomes among a large sample of TAC clients. Results demonstrated that, despite similar levels of physical injury, people who attribute responsibility for accidents to other persons or circumstances experience poorer physical and mental health recovery in comparison to those who attribute responsibility to themselves.

INTroducing a care bundle to prevent pressure injury (INTACT) in at-risk patients: a protocol for a cluster randomised trial

BACKGROUND: Pressure injuries are a significant clinical and economic issue, affecting both patients and the health care system. Many pressure injuries in hospitals are facility acquired, and are largely preventable. Despite growing evidence and directives for pressure injury prevention, implementation of preventative strategies is suboptimal, and pressure injuries remain a serious problem in hospitals. OBJECTIVES: This study will test the effectiveness and cost-effectiveness of a patient-centred pressure injury prevention care bundle on the development of hospital acquired pressure injury in at-risk patients. DESIGN: This is a multi-site, parallel group cluster randomised trial. The hospital is the unit of randomisation. METHODS: Adult medical and surgical patients admitted to the study wards of eight hospitals who are (a) deemed to be at risk of pressure injury (i.e. have reduced mobility), (b) expected to stay in hospital for ≥48h, (c) admitted to hospital in the past 36h; and (d) able to provide informed consent will be eligible to participate. Consenting patients will receive either the pressure injury prevention care bundle or standard care. The care bundle contains three main messages: (1) keep moving; (2) look after your skin; and (3) eat a healthy diet. Nurses will receive education about the intervention. Patients will exit the study upon development of a pressure injury, hospital discharge or 28 days, whichever comes first; transfer to another hospital or transfer to critical care and mechanically ventilated. The primary outcome is incidence of hospital acquired pressure injury. Secondary outcomes are pressure injury stage, patient participation in care and health care costs. A health economic sub-study and a process evaluation will be undertaken alongside the trial. Data will be analysed at the cluster (hospital) and patient level. Estimates of hospital acquired pressure injury incidence in each group, group differences and 95% confidence interval and p values will be reported. DISCUSSION: To our knowledge, this is the first trial of an intervention to incorporate a number of pressure injury prevention strategies into a care bundle focusing on patient participation and nurse-patient partnership. The results of this study will provide important information on the effectiveness and cost-effectiveness of this intervention in preventing pressure injuries in at-risk patients. If the results confirm the utility of the developed care bundle, it could have a significant impact on clinical practice worldwide. TRIAL REGISTRATION: This trial is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12613001343796.

Development of mental health first aid guidelines for deliberate non-suicidal self-injury: a Delphi study

BACKGROUND: It is estimated that around 4% of the population engages, or has engaged, in deliberate non-suicidal self-injury. In clinical samples, the figures rise as high as 21%. There is also evidence to suggest that these figures may be increasing. A family member or friend may suspect that a person is injuring themselves, but very few people know how to respond if this is the case. Simple first aid guidelines may help members of the public assist people to seek and receive the professional help they require to overcome self-injury.

METHODS: This research was conducted using the Delphi methodology, a method of reaching consensus in a panel of experts. Experts recruited to the panels included 26 professionals, 16 people who had engaged in self-injurious behaviour in the past and 3 carers of people who had engaged in self-injurious behaviour in the past. Statements about providing first aid to a person engaged in self-injurious behaviour were sought from the medical and lay literature, but little was found. Panel members were asked to respond to general questions about first aid for NSSI in a variety of domains and statements were extracted from their responses. The guidelines were written using the items most consistently endorsed by the consumer and professional panels.

RESULTS: Of 79 statements rated by the panels, 18 were accepted. These statements were used to develop the guidelines appended to this paper.

CONCLUSION: There are a number of actions which are considered to be useful for members of the public when they encounter someone who is engaging in deliberate, non-suicidal self-injury. These guidelines will be useful in revising curricula for mental health first aid and NSSI first aid training programs. They can also be used by members of the public who want immediate information about how to assist a person who is engaging in such behaviour.

Using transcranial magnetic stimulation to quantify electrophysiological changes following concussive brain injury: a systematic review

Mild traumatic brain injury (mTBI) and sports concussion are a growing public health concern, with increasing demands for more rigorous methods to quantify changes in the brain post-injury. Electrophysiology, and in particular, transcranial magnetic stimulation (TMS), have been demonstrated to provide prognostic value in a range of neurological conditions; however, no review has quantified the efficacy of TMS in mTBI/concussion. In the present study, we present a systematic review and critical evaluation of the scientific literature from 1990 to 2014 that has used TMS to investigate corticomotor excitability responses at short-term (< 12 months), medium-term (1-5 years), and long-term (> 5 years) post-mTBI/concussion. Thirteen studies met the selection criteria, with six studies presenting short-term changes, five studies presenting medium-term changes, and two studies presenting long-term changes. Irrespective of time post-concussion, change in intracortical inhibition was the most reported observation. Other findings included increased stimulation threshold, and slowed neurological conduction time. Although currently limited, the data suggest that TMS has prognostic value in detecting neurophysiological changes post-mTBI/concussion.

Nurses' perceptions of using an evidence-based care bundle for initial emergency nursing management of patients with severe traumatic brain injury: A qualitative study.

Evidence to guide initial emergency nursing care of patients with severe traumatic brain injury (TBI) in Thailand is currently not available in a useable form. A care bundle was used to summarise an evidence-based approach to the initial emergency nursing management of patients with severe TBI and was implemented in one Thai emergency department. The aim of this study was to describe Thai emergency nurses' perceptions of care bundle use. A descriptive qualitative study was used to describe emergency nurses' perceptions of care bundle use during the implementation phase (Phase-One) and then post-implementation (Phase-Two). Ten emergency nurses participated in Phase-One, while 12 nurses participated in Phase-Two. In Phase-One, there were five important factors identified in relation to use of the care bundle including quality of care, competing priorities, inadequate equipment, agitated patients, and teamwork. In Phase Two, participants perceived that using the care bundle helped them to improve quality of care, increased nurses' knowledge, skills, and confidence. Care bundles are one strategy to increase integration of research evidence into clinical practice and facilitate healthcare providers to deliver optimal patient care in busy environments with limited resources.

Using an evidence-based care bundle to improve Thai emergency nurses' knowledge of care for patients with severe traumatic brain injury

There is known variation in Thai nurses' knowledge regarding the best available evidence for care of patients with severe traumatic brain injury. The purpose of this study was to examine the impact of an evidence-based care bundle on Thai emergency nurses' knowledge regarding management of patients with severe traumatic brain injury. A pre-test/post-test design was used. The study intervention was an evidence-based care bundle for initial nursing management of patients with severe traumatic brain injury. Data were collected from 31 Registered Nurses using multiple choice questions. Results revealed a statistically significant improvement in overall knowledge scores after care bundle implementation (p < 0.001). There were statistically significant improvements in five areas of knowledge: understanding of target end-tidal carbon dioxide levels (p < 0.001), implications of hypocapnia in severe traumatic brain injury (p = 0.01), implications of hypercapnia in severe traumatic brain injury (p = 0.02), importance of maintaining head and neck in neutral position (p = 0.05), and administration of sedatives and analgesics in severe traumatic brain injury (p = 0.01). This study suggested that implementation of an evidence-based care bundle improved emergency nurses' knowledge regarding management of patients with severe traumatic brain injury.

Do surgeons treat their patients like they would treat themselves?

Background - There is substantial unexplained geographical and surgeon-to-surgeon variation in rates of surgery. One would expect surgeons to treat patients and themselves similarly based on best evidence and accounting for patient preferences.

Questions/purposes - (1) Are surgeons more likely to recommend surgery when choosing for a patient than for themselves? (2) Are surgeons less confident in deciding for patients than for themselves?

Methods - Two hundred fifty-four (32%) of 790 Science of Variation Group (SOVG) members reviewed 21 fictional upper extremity cases (eg, distal radius fracture, De Quervain tendinopathy) for which surgery is optional answering two questions: (1) What treatment would you choose/recommend: operative or nonoperative? (2) On a scale from 0 to 10, how confident are you about this decision? Confidence is the degree that one believes that his or her decision is the right one (ie, most appropriate). Participants were orthopaedic, trauma, and plastic surgeons, all with an interest in treating upper extremity conditions. Half of the participants were randomized to choose for themselves if they had this injury or illness. The other half was randomized to make treatment recommendations for a patient of their age and gender. For the choice of operative or nonoperative, the overall recommendation for treatment was expressed as a surgery score per surgeon by dividing the number of cases they would operate on by the total number of cases (n = 21), where 100% is when every surgeon recommended surgery for every case. For confidence, we calculated the mean confidence for all 21 cases per surgeon; overall score ranges from 0 to 10 with a higher score indicating more confidence in the decision for treatment.

Results - Surgeons were more likely to recommend surgery for a patient (44.2% ± 14.0%) than they were to choose surgery for themselves (38.5% ± 15.4%) with a mean difference of 6% (95% confidence interval [CI], 2.1%–9.4%; p = 0.002). Surgeons were more confident in deciding for themselves than they were for a patient of similar age and gender (self: 7.9 ± 1.0, patient: 7.5 ± 1.2, mean difference: 0.35 [CI, 0.075–0.62], p = 0.012).

Conclusions - Surgeons are slightly more likely to recommend surgery for a patient than they are to choose surgery for themselves and they choose for themselves with a little more confidence. Different perspectives, preferences, circumstantial information, and cognitive biases might explain the observed differences. This emphasizes the importance of (1) understanding patients’ preferences and their considerations for treatment; (2) being aware that surgeons and patients might weigh various factors differently; (3) giving patients more autonomy by letting them balance risks and benefits themselves (ie, shared decision-making); and (4) assessing how dispassionate evidence-based decision aids help inform the patient and influences their decisional conflict.

Level of Evidence - Level III, diagnostic study.

Using an evidence-based care bundle to improve initial emergency nursing management of patients with severe traumatic brain injury

AIMS AND OBJECTIVES: To test the feasibility of an evidence-based care bundle in a Thai emergency department. The specific objective of this study was to examine the impact of the implementation of the care bundle on the initial emergency nursing management of patients with severe traumatic brain injury. BACKGROUND: A care bundle approach is one strategy used to improve the consistency, quality and safety of emergency care for different patients groups, however, has not been tested in patients with severe traumatic brain injury. DESIGN: A pretest/post-test design was used. The study intervention was an evidence-based care bundle for initial emergency nursing management of patients with severe traumatic brain injury. METHODS: Nonparticipant observations were conducted between October 2012-June 2013 at an emergency department of a 640 bed regional hospital in Southern Thailand. The initial emergency nursing care was observed in 45 patients with severe traumatic brain injury: 20 patients in the pretest period and 25 patients in the post-test period. RESULTS: There were significant improvements in clinical care of patients with severe traumatic brain injury after implementation of the care bundle: (1) use of end-tidal carbon dioxide monitoring, (2) frequency of respiratory rate assessment, (3) frequency of pulse rate and blood pressure assessment, and (4) patient positioning. CONCLUSION: This study demonstrated that implementation of an evidence-based care bundle improved specific elements of emergency nurses' clinical management of patients with severe traumatic brain injury. RELEVANCE TO CLINICAL PRACTICE: The study suggests that a care bundle approach can be used as a strategy to improve emergency nursing care of patients with severe traumatic brain injury.

Nonsuicidal self-injury in Indian adolescents: nonexistent or unacknowledged?

Nonsuicidal self-injury (NSSI) has been a neglected entity in low- and middle-income countries (LMICs). In this correspondence (letter to the editor), authors are advocating for greater research in this area in LMICs as it will help to compare and contrast prevalence rates of NSSI in these countries with high-income countries (HICs), identify context-specific risk and protective factors to better understand the pathophysiology of NSSI and devise context-specific interventions resulting in improvement in adolescent mental health worldwide.

Review of the literature on the use of social media by people with traumatic brain injury (TBI)

Purpose: To review the literature relating to use of social media by people with a traumatic brain injury (TBI), specifically its use for social engagement, information exchange or rehabilitation.

Method: A systematic review with a qualitative meta-synthesis of content themes was conducted. In June 2014, 10 databases were searched for relevant, peer-reviewed research studies in English that related to both TBI and social media.

Results: Sixteen studies met the inclusion criteria, with Facebook™ and Twitter™ being the most common social media represented in the included studies. Content analysis identified three major categories of meaning in relation to social media and TBI: (1) risks and benefits; (2) barriers and facilitators; and (3) purposes of use of social media. A greater emphasis was evident regarding potential risks and apparent barriers to social media use, with little focus on facilitators of successful use by people with TBI.

Conclusions: Research to date reveals a range of benefits to the use of social media by people with TBI however there is little empirical research investigating its use. Further research focusing on ways to remove the barriers and increase facilitators for the use of social media by people with TBI is needed. Implications for Rehabilitation: Communication disabilities following traumatic brain injury (TBI) can be wide-ranging in scope and social isolation with loss of friendships after TBI is common. For many people, social media is rapidly becoming a usual part of everyday communication and its use has the potential to increase communication and social participation for people with TBI.There is emerging evidence and commentary regarding the perceived benefits and risks, barriers and facilitators and purposes of use of social media within the TBI population.Risks associated with using social media, and low accessibility of social media sites, form barriers to its use. Facilitators for social media use in people with TBI include training the person with TBI and their communication partners in ways to enjoy and use social media safely.There is minimal rigorous evaluation of social media use by people with TBI and scant information regarding social media use by people with communication disabilities after TBI. Further investigation is needed into the potential benefits of social media use on communication, social participation and social support with the aim of reducing social isolation in people with TBI.
