The current climate of increasing performance expectations and diminishing resources, along with innovations in evidence-based practices (EBPs), creates new dilemmas for substance abuse treatment providers, policymakers, funders, and the service delivery system. This paper describes findings from baseline interviews with representatives from 49 state substance abuse authorities (SSAs). Interviews assessed efforts aimed at facilitating EBP adoption in each state and the District of Columbia. Results suggested that SSAs are concentrating more effort on EBP implementation strategies such as education, training, and infrastructure development, and less effort on financial mechanisms, regulations, and accreditation. The majority of SSAs use EBPs as a criterion in their contracts with providers, and just over half reported that EBP use is tied to state funding. To date, Oregon remains the only state with legislation that mandates treatment expenditures for EBPs; North Carolina follows suit with legislation that requires EBP promotion within current resources.

Currently, social work is witnessing a quite polarized debate about what should be the basis for good practice. Simply stated, the different attempts to define the required basis for effective and accountable interventions in social work practice can be grouped in two paradigmatic positions, which seem to be in strong opposition to each other. On the one hand the highly influential evidence based practice movement highlights the necessity to base practice interventions on proven effectiveness from empirical research. Despite some variations, such as between narrow conceptions of evidence based practice (see e.g. McNeece/Thyer, 2004) and broader approaches to it (see e.g. Gambrill, 1999, 2001, 2008), the evidence based practice movement embodies a positivist orientation and more explicitly scientific aspirations of social work by using positivistic empirical strategies. Critics of the evidence based practice movement argue that its narrow epistemological assumptions are not appropriate for the understanding of social phenomena and that evidence based guidelines to practice are insufficient to deal with the extremely complex activities social work practice requires in different and always somewhat unique practice situations (Webb, 2001; Gray & Mc Donald, 2006; Otto, Polutta &Ziegler, 2009). Furthermore critics of evidence based practice argue that it privileges an uncritical and a-political positivism which seems highly problematic in the current climate of welfare state reforms, in which the question ‘what works’ is highly politicized and the legitimacy of professional social work practice is being challenged maybe more than ever before (Kessl, 2009). Both opponents and proponents of evidence based practice argue on the epistemological, the methodological and the ethical level to sustain their point of view and raise fundamental questions about the real nature of social work practice, so that one could get the impression that social work is really at the crossroads between two very different conceptions of social work practice and its further professional development (Stepney, 2009). However, this article is not going to merely rehearse the pro and contra of different positions that are being invoked in the debate about evidence based practice. Instead it aims to go further by identifying the dilemmas underlying these positions which - so it is argued – re-emerge in the debate about evidence based practice, but which are older than this debate. They concern the fundamental ambivalence modern professionalization processes in social work were subjected to from their very beginnings.

Introduction: A need for baccalaureate prepared nurses to find and use evidence in practice exists. Whereas using this evidence in practice may be a masters level expectation, current practice demands that baccalaureate prepared nurses acquire a basic understanding of how to use evidence in practice. Nursing students at the senior level have had exposure to critiquing research, however, they have difficulty translating evidence to practice. [See PDF for complete abstract]

The democratic deficit of evidence-based policymaking and the little attention the approach pays to values and norms have repeatedly been criticized. This article argues that direct-democratic campaigns may provide an arena for citizens and stakeholders to debate the belief systems inherent to evidence. The study is based on a narrative analysis of Program for International Student Assessment (PISA) reports, as well as of newspaper coverage and governmental information referring to PISA in Swiss direct-democratic campaigns on a variety of school policy issues. The findings show that PISA reports are discursive instruments rather than ‘objective evidence’. The reports promote a narrative of economic progress through educational evidence that is adopted without scrutiny by governmental coalitions in direct-democratic campaigns to justify school policy reforms. Yet, the dominant PISA narrative is contested in two counter-narratives, one endorsed by numerous citizens, the other by a group of experts. These counter-narratives question how PISA is used by an ‘expertocracy’ to prescribe reforms, as well as the performance ideology inherent to. Overall, these findings suggest that direct-democratic campaigns may make more transparent how evidence is produced and used according to existing belief systems. Evidence, on the other hand, may be a stimulus for democratic discourse by feeding the debate with potential policy problems and solution. Thus, direct-democratic debates may reconcile normative positions of citizens with the desire to base decisions on empirical evidence.

The ability of public health practitioners (PHPs) to work efficiently and effectively is negatively impacted by their lack of knowledge of the broad range of evidence-based practice information resources and tools that can be utilized to guide them in their development of health policies and programs. This project, a three-hour continuing education hands-on workshop with supporting resources, was designed to increase knowledge and skills of these resources. The workshop was presented as a pre-conference continuing education program for the Texas Public Health Association (TPHA) 2008 Annual Conference. Topics included: identification of evidence-based practice resources to aid in the development of policies and programs; identification of sources of publicly available data; utilization of data for community assessments; and accessing and searching the literature through a collection of databases available to all citizens of Texas. Supplemental resources included a blog that served as a gateway to the resources explored during the presentation, a community assessment workbook that incorporates both Healthy People 2010 objectives and links to reliable sources of data, and handouts providing additional instruction on the use of the resources covered during the workshop.^ Before- and after-workshop surveys based on Kirkpatrick's 4-level model of evaluation and the Theory of Planned Behavior were administered. Of the questions related to the trainer, the workshop, and the usefulness of the workshop, participants gave "Good" to "Excellent" responses to all one question. Confidence levels overall increased a statistically significant amount; measurements of attitude, social norms, and control showed no significant differences before and after the workshop. Lastly, participants indicated they were likely to use resources shown during the workshop within a one to three month time period on average. ^ The workshop and creation of supplemental resources served as a pilot for a funded project that will be continued with the development and delivery of four 4-week long webinar-based training sessions to be completed by December 2008. ^

Radiation therapy has been used as an effective treatment for malignancies in pediatric patients. However, in many cases, the side effects of radiation diminish these patients’ quality of life. In order to develop strategies to minimize radiogenic complications, one must first quantitatively estimate pediatric patients’ relative risk for radiogenic late effects, which has not become feasible till recently because of the calculational complexity. The goals of this work were to calculate the dose delivered to tissues and organs in pediatric patients during contemporary photon and proton radiotherapies; to estimate the corresponding risk of radiogenic second cancer and cardiac toxicity based on the calculated doses and on dose-risk models from the literature; to test for the statistical significance of the difference between predicted risks after photon versus proton radiotherapies; and to provide a prototype of an evidence-based approach to selecting treatment modalities for pediatric patients, taking second cancer and cardiac toxicity into account. The results showed that proton therapy confers a lower predicted risk of radiogenic second cancer, and lower risks of radiogenic cardiac toxicities, compared to photon therapy. An uncertainty analysis revealed that the qualitative findings of this study are insensitive to changes in a wide variety of host and treatment related factors.

Background. The United Nations' Millennium Development Goal (MDG) 4 aims for a two-thirds reduction in death rates for children under the age of five by 2015. The greatest risk of death is in the first week of life, yet most of these deaths can be prevented by such simple interventions as improved hygiene, exclusive breastfeeding, and thermal care. The percentage of deaths in Nigeria that occur in the first month of life make up 28% of all deaths under five years, a statistic that has remained unchanged despite various child health policies. This paper will address the challenges of reducing the neonatal mortality rate in Nigeria by examining the literature regarding efficacy of home-based, newborn care interventions and policies that have been implemented successfully in India. ^ Methods. I compared similarities and differences between India and Nigeria using qualitative descriptions and available quantitative data of various health indicators. The analysis included identifying policy-related factors and community approaches contributing to India's newborn survival rates. Databases and reference lists of articles were searched for randomized controlled trials of community health worker interventions shown to reduce neonatal mortality rates. ^ Results. While it appears that Nigeria spends more money than India on health per capita ($136 vs. $132, respectively) and as percent GDP (5.8% vs. 4.2%, respectively), it still lags behind India in its neonatal, infant, and under five mortality rates (40 vs. 32 deaths/1000 live births, 88 vs. 48 deaths/1000 live births, 143 vs. 63 deaths/1000 live births, respectively). Both countries have comparably low numbers of healthcare providers. Unlike their counterparts in Nigeria, Indian community health workers receive training on how to deliver postnatal care in the home setting and are monetarily compensated. Gender-related power differences still play a role in the societal structure of both countries. A search of randomized controlled trials of home-based newborn care strategies yielded three relevant articles. Community health workers trained to educate mothers and provide a preventive package of interventions involving clean cord care, thermal care, breastfeeding promotion, and danger sign recognition during multiple postnatal visits in rural India, Bangladesh, and Pakistan reduced neonatal mortality rates by 54%, 34%, and 15–20%, respectively. ^ Conclusion. Access to advanced technology is not necessary to reduce neonatal mortality rates in resource-limited countries. To address the urgency of neonatal mortality, countries with weak health systems need to start at the community level and invest in cost-effective, evidence-based newborn care interventions that utilize available human resources. While more randomized controlled studies are urgently needed, the current available evidence of models of postnatal care provision demonstrates that home-based care and health education provided by community health workers can reduce neonatal mortality rates in the immediate future.^

Purpose: To discuss the approach and recommendations related to the adoption of school based curriculum for violence prevention. Findings: Preliminary assessments suggest that middle and high school youth experience a variety of forms of violence in social and dating relationships. Such experiences have negative academic, behavioral and emotional consequences. Conclusions: The authors have clearly illuminated the need for addressing the phenomenon of dating violence. The field could benefit from more robust evidenced-based investigations that substantiate that interventions have an impact beyond attitudinal changes toward the behavior. Such academic endeavors will provide a platform to validate the inclusion of such information in a school based curriculum as act as a call for action for broad based interventions.
