Evidence-based public health: what does it offer developing countries?

The global burden of disease and illness is primarily situated in developing countries. As developing countries have limited resources, it is particularly important to invest in public health and health promotion strategies that are effective. Systematic reviews are central to evidence-based public health and health promotion practice and policy. This paper discusses issues surrounding the relevance of evidence-based public health and systematic reviews to the health of developing countries. It argues that there is a lack of systematic reviews relevant to the health priorities of developing countries; many interventions reviewed can not be implemented in resource-poor situations; and, a limited amount of primary research is conducted in developing countries. The paper further argues that improvements in public health are determined not only by effective health services and interventions, but through an approach that includes other sectors and influences broader structural and systematic barriers to health. Given the social complexity of human development, and the inter-sections amongst different development goals, there is no question that gains in developing country public health are unlikely to emerge from systematic reviews alone, but will require decisions about inter-sectoral collaboration and social policy initiatives. Nonetheless, evidence around intervention effectiveness has an important role to play in addressing health priorities in developing countries and resource-poor areas. The public health evidence base urgently needs strengthening, with dedicated effort towards increasing the relevance of primary evidence and systematic reviews.

Corporate entrepreneurship and innovation part 2 : a role- and process-based approach

Purpose – To extend the discussion held in part 1, and develop a two-tier fifth-generation model of corporate entrepreneurship and innovation. Design/methodology/approach – The components that have been synthesized from a review of the literature in Part 1 are extended using evidence from the literature. These components are used to construct a two-tier model of corporate entrepreneurship and innovation; a macro model which presents the high-level environmental drivers of innovation and a micro model that discusses the contextual factors that underpin the corporate entrepreneurship and innovation process. Findings – From the analysis conducted in part 1 it is evident that there is a strong relationship between the role of the corporate entrepreneur and the innovation process. It is suggested that by separating the corporate entrepreneur from the innovation process previous models have been overly reductionist in their construction, and their utility has, as a consequence, been severely constrained. The study therefore combines the role and activities of the entrepreneur with the innovation process into a unified framework. In doing so the paper develops a two-tier fifth-generation model of corporate entrepreneurship and innovation. The final sections of the paper present the model's implications for management and suggestions for further research. Originality/value – This paper fulfils an identified gap in the literature, namely the development of a new holistic model of corporate entrepreneurship and innovation, which illustrates the environmental and contextual relationships between the corporate entrepreneur and the innovation process.

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.

The NICHD protocol: a review of an internationally-used evidence-based tool for training child forensic interviewers

Purpose
– The purpose of this paper is to review an evidence-based tool for training child forensic interviewers called the National Institute of Child Health and Human Development Protocol (NICHD Protocol), with a specific focus on how the Protocol is being adapted in various countries.
Design/methodology/approach
– The authors include international contributions from experienced trainers, practitioners, and scientists, who are already using the Protocol or whose national or regional procedures have been directly influenced by the NICHD Protocol research (Canada, Finland, Israel, Japan, Korea, Norway, Portugal, Scotland, and USA). Throughout the review, these experts comment on: how and when the Protocol was adopted in their country; who uses it; training procedures; challenges to implementation and translation; and other pertinent aspects. The authors aim to further promote good interviewing practice by sharing the experiences of these international experts.
Findings
– The NICHD Protocol can be easily incorporated into existing training programs worldwide and is available for free. It was originally developed in English and Hebrew and is available in several other languages.
Originality/value
– This paper reviews an evidence-based tool for training child forensic interviewers called the NICHD Protocol. It has been extensively studied and reviewed over the past 20 years. This paper is unique in that it brings together practitioners who are actually responsible for training forensic interviewers and conducting forensic interviews from all around the world.

Stop jumping the gun : a call for evidence-based invasive predator management

Invasive mammalian predators are major drivers of species extinctions globally. To protect native prey, lethal control is often used with the aim of reducing or exterminating invasive predator populations. The efficacy of this practice, however, is often not considered despite multiple practical and ecological factors that can limit success. Here, we summarize contemporary knowledge regarding the use and challenges of both lethal control and alternative approaches for reducing invasive predator impacts. As the prevailing management approach, we outline four key issues that can compromise the effectiveness of lethal control: release of herbivore and mesopredator populations, disruption of predator social systems, compensatory predator immigration, and ethical concerns. We then discuss the relative merits and limitations of four alternative approaches that may enhance conservation practitioner's ability to effectively manage invasive predators: top-predator conservation or reintroduction, maintaining habitat complexity, exclusion fencing, and behavioral and evolutionary ecology. Considerable uncertainty remains regarding the effectiveness of management approaches in different environmental contexts. We propose that the deficiencies and uncertainties outlined here can be addressed through a combination of adaptive management, expert elicitation, and cost-benefit analyses. Improved management of invasive predators requires greater consideration and assessment of the full range of management approaches available.

Preventing tobacco use and harm: what is evidence based policy?

The majority of tobacco users commence in early to mid-adolescence. Tobacco smoking can be characterised as a chronic, relapsing disorder. While risk increases with amount smoked, there is no safe level of use (i.e., all use is risky). Duration of use is the most important predictor of premature death with the majority of excess morbidity and mortality avoidable if people quit before middle age. Investment in initiatives that reduce smoking among pregnant women and those at risk of cardiovascular disease provide quickest returns -in reduced health care episodes and expenditure.  Measures that successfully reduce smoking among parents probably reduce smoking uptake by children, and high levels of smoking among both children and parents appear to be associated with higher levels of illicit drug use.
The evidence base for pharmcotherapies in the treatment of tobacco dependence is very strong. Population-level initiatives such as tax increases, mass media-led campaigns and smoke-free policies are all highly cost-effective in reducing population-smoking levels, including among children and young people.
Australian tobacco control initiatives have been based on "social ecology" conceptualisations of the problem, which acknowledge the pivotal role of the media in shaping social values, and public and political opinion.
Broad social change, as well as more focused prevention and cessation initiatives, has drawn heavily on research findings from the behavioural sciences. Considerable effort (mainly, in Australian, in the NGO sector) has gone into documenting policy inputs and monitoring impact and outcome measures.
This chapter discusses why conceptualising tobacco-related harm from legal, economic and social policy perspectives should also help build support for tobacco control policy among academic and practising economists and lawyers, and in the business, welfare and government sectors.

Coronary angiography observations: evidence-based or ritualistic practice?

Objective: The purposes of this study were to describe the incidence and occurrence of femoral artery bleeding during the first 6 hours after coronary angiography and to determine whether there is a relationship between  current postangiogram observation protocols and the detection of  complications.

Design: This was a prospective descriptive study.

Setting: The study was conducted in 3 university hospitals in Melbourne, Australia.

Patients: Subjects included 55 patients representing the complication rate of 1075 patients, mean age 61 years (SD, 12), 69% male.

Results: About 5.1% of patients had 1 or more incidents of bleeding  requiring manual compression. In 4.2% of patients, bleeding occurred within 6 hours of angiography. Bleeding occurred a median of 2.02 hours (Q1 = 45 minutes, Q3 = 4.31 hours) after angiography. Patients without pressure bandaging bled a median of 1.32 hours (Q1 = 36.50 minutes, Q3 = 2.59 hours) after angiography. Patients with pressure bandaging bled a median of 4.75 hours (Q1 = 2.25 hours, Q3 = 7.28 hours) after angiography. In 40.6% of cases, bleeding was detected through the patient’s call for assistance, and in 59.4% of cases nurses noted bleeding while checking the puncture site. Postcatheter observations were recorded 23.70 (SD, 14.60) minutes before the bleeding incident. There were no significant changes in vital signs, systolic blood pressure (P > .05), diastolic blood pressure (P > .05), or pulse (P > .05) before or during a bleeding episode. All were within normal parameters. No neurovascular assessment anomalies were detected.

Conclusion: The use of pressure bandaging has a significant effect on the incidence and pattern of bleeding. Routine vital sign measurement has no relevance in detecting local complications after angiography. The most significant complication is bleeding that requires manual compression. Detection is through frequent puncture site observation and patient recognition and communication.

Is it only 'what works' that 'counts' in new knowledge economies? Evidence-based practice, educational research and teacher education in Australia

Recent texts on globalisation and education policy refer to the rapid flow of education policy texts producing or responding to common trends across nation states with the emergence of new knowledge economies. These educational policies are shaping what counts as research and the dynamics between research, policy, and practice in schools, creating new types of relationships between universities, the public, the professions, government, and industry. The trend to evidence-based policy and practice in Australian schools is used to identify key issues within wider debates about the ‘usefulness’ of educational research and the role of universities and university-based research in education in new knowledge economies.

A problem-based approach to clinical education in dietetics

Developing the clinical skills and knowledge of dietetic students provides a challenge for both universities and health care agencies. Deakin University has recently adopted a group learning model using problem-based learning to deliver the clinical component of the Master of Nutrition and Dietetics course. This approach was designed to enhance integration of clinical theory and practice, develop closer links between on-campus and off-campus learning environments and provide students with more active learning experiences. The impact of the new approach was evaluated using student questionnaires, academic and competency outcomes, and a focus group convened with hospital supervisors. The evaluation indicated that students generally thought that this method of learning had helped to integrate their basic knowledge with dietetic case management. There was no difference in academic scores from the previous year and an apparent reduction in the number of students requiring additional placement time to mee t competency standards. Hospital supervisors were supportive of the changes, although they had some reservations regarding the time and structure of clinical placements. As a result of this evaluation, recommendations for future development of the program include introducing problem-based learning to students earlier in their course, providing additional placement days during the block and increasing the amount of time dedicated to more complex topics. Based on the evaluation results obtained, this collaborative learning using a problem-based approach will continue to be used in the clinical education program at Deakin University.

Evidence-based strategies to promote physical activity among children, adolescents and young adults: review and update

This paper updates evidence reviewed in the first edition of Getting Australia Active on effective physical activity (PA) intervention strategies among children, adolescents and young adults. Intervention studies published between 1999 and September 2003 were identified using electronic databases and hand searching. A total of 28 discrete studies were identified (31 papers). Six of nine studies reported significant effects on child or youth PA in school settings. Those that incorporated whole-of-school approaches including curriculum, policy and environmental strategies appeared to be more effective than those that incorporated curriculum-only approaches. Five of 10 studies with children and two of five studies with adolescents reported increased PA or decreased sedentary behaviour in other settings. Interventions that included contact with families generally appeared to be most effective. One study with adolescents provided some evidence of the potential effectiveness of interventions based in primary care. Two of four papers reported modest short-term results among young adults, including increased PA stage of change or a higher likelihood of being adequately physically active, but none showed any evidence of sustained increases in PA. There is an urgent need for additional studies examining interventions aimed at young adults. Across the three life stages, future studies should include objective PA measures, longer-term follow-up, larger sample sizes, a specific focus on PA (rather than weight) and culturally-specific strategies that build evidence in Australian populations. Future studies should target high risk groups and a broad range of settings and strategies focusing on reducing sedentary behaviours as well as increasing PA.

Rationale and design of the national benchmarking and evidence-based national clinical guidelines for chronic heart failure management programs study

OBJECTIVES: The National Benchmarks and Evidence-Based National Clinical Guidelines for Heart Failure Management Programs Study is a national, multicenter study designed to determine the nature, range, and effect of interventions applied by chronic heart failure management programs (CHF-MPs) throughout Australia on patient outcomes. Its primary objective is to use these data to develop national benchmarks and evidence-based clinical guidelines and optimize their cost-effective application by reducing quality and outcome variability. DATA SOURCES/STUDY SETTING: Primary data will be collected from CHF-MP coordinators and CHF patients enrolled in these programs on a national basis. Secondary outcome data will be collected from a national morbidity record and from patients' medical records. STUDY DESIGN: Stage I of the study involves a prospective clinical audit of all CHF-MPs throughout Australia (n = 45) to determine the extent of variability in programs currently. Stage II is a prospective cross-sectional survey design enrolling 1,500 patients (average of 40 patients per program) to firstly determine the typical profile of patients being managed via a CHF-MP in Australia and, secondly, the subsequent morbidity and mortality during the 6-month follow-up. Outcome data will be subject to multivariate analysis to determine the key components of care in this regard. All study data will be then examined in the final stage of the study (III) to develop national benchmarks for the application and auditing of CHF-MPs in Australia. CONCLUSION: Variability in patient outcomes is a product of heterogeneity among CHF-MPs. The development of national benchmarks will minimize such heterogeneity and will provide a greater level of evidence for their cost-effective application.

Emergency nurses' opinions regarding paediatric fever: the effect of an evidence-based education program

Introduction: The beliefs and opinions of individual nurses are key factors in clinical decisions. Emergency nurses’ clinical decisions related to paediatric fever establish emergency department norms, provide role-modelling for both peers and parents, underpin clinical management of febrile children, and influence fever management advice given to parents. Aim: This study aimed to examine: (i) the opinions of emergency nurses regarding paediatric fever, and (ii) the effect of an evidence-based education program on the opinions of emergency nurses regarding paediatric fever. Method: This study used a prospective pre-test/post-test design. The primary outcome measure was emergency nurses’ opinions measured using the ‘General Opinions about Fever Management in Children’ survey. The intervention for the study was two tutorials. Pre-test data was collected in June 2005 and post-test data was collected during August 2005. Results: Thirty-one emergency nurses participated in the study. There were a number of positive changes in emergency nurses’ opinions regarding paediatric fever as a function of an evidence-based educational intervention. Major domains of change were relationship between temperature and illness severity/risk of harm, use and effects of antipyretic medication and febrile convulsions.  Conclusion: Emergency nurses are an important source of information for parents leaving the emergency department with a febrile child. Opinions can be a major influence in nurses’ clinical decisions and many fever  management strategies used by health care professionals are reflective of individual beliefs rather than the best available evidence. The results of this study showed a number of positive changes in emergency nurses’ opinions regarding paediatric fever as a function of an evidence-based educational intervention.

Evidence based practice: are critical care nurses ready for it?

In the emergence of the evidence based practice movement, critical care nurses have struggled to identify scientific evidence on which to base their clinical practice. While the lack of critical care nursing research is a major concern, other important issues have significantly stalled the implementation of evidence even when it is available. A descriptive study of 274 critical care nurses was undertaken to examine nursing research activity in Victorian critical care units. The study aimed to identify critical care nurses' research skills, the barriers encountered in participation and implementation and the current availability of resources.

Results revealed that 42 per cent of the nurses who participated in the study believed that they were not prepared adequately to evaluate research, and less than a third believed they were sufficiently skilled to conduct valid scientific studies. An association was found between nurses' ability to confidently perform research activities and higher academic qualifications. The study found that there is a lack of organisational support and management commitment for the development of evidence based nursing.

In order to facilitate the implementation of evidence based practice, clinicians must be made aware of the available resources, be educated and mentored when carrying out and using clinical research, and be supported in professional initiatives that promote evidence based practice. It is argued that this will have positive implications for patient outcomes in the critical care environment.
