Abstract Background: Although non-specific low back pain (LBP) is known to be multifactorial, studies from across the globe have documented their higher prevalence in nurses. This systematic review was conducted to ascertain whether this much-documented association constitutes a causal relationship, and whether there is a discernible threshold of exposures associated with this elevated risk. Methods: PRISMA guidelines were followed and standard critical appraisal tools were applied. The outcome of interest was non-specific LBP or back injury; exposure was “performing nursing duties.” Applicable studies, published in English during 1980–2012, were identified through database searches, screened against preset inclusion/exclusion criteria. Ergonomic assessments of nursing tasks were included along with epidemiological studies. Bradford Hill considerations for causation were utilized as a framework for discussing findings. Findings: Of 987 studies identified, 89 qualified for inclusion, comprising 21 longitudinal, 36 cross-sectional analytic, 23 descriptive biomechanical/ergonomic, and 9 review studies. Overall studies showed that nursing activities conferred increased risk for, and were associated with back disorders regardless of nursing technique, personal characteristics, and non-work-related factors. Patient handling appears to confer the highest risk, but other nursing duties are also associated with elevated risk, and confound dose–response assessments related to patient handling alone. Associations were strong, consistent, temporally possible, plausible, coherent, and analogous to other exposure-outcomes, with risk estimates ranging from 1·2 to 5·5 depending on definitions. A threshold of nursing activities below which the risk of back disorders is not elevated has not been established. Interpretation: Notwithstanding the bio-psycho-social nature of LBP, and complexities of studying this area, sufficient evidence exists of a causal relationship between nursing tasks and back disorders to warrant new policies.

BACKGROUND Joint health and safety committees (JHSCs) are widely acknowledged as important to a healthy and safe work environment. However, it is also generally believed that having a JHSC is necessary but not sufficient; the JHSC must be effective. METHODS A systematic review was undertaken to find empirical studies regarding the effectiveness of JHSCs; realist review methodology was applied to determine context-mechanism-outcome patterns. Experts from across Canada and from various sectors and perspectives including government, employers, and unions, were brought together to inform the synthesis. RESULTS Thirty-one studies met inclusion criteria. Mechanisms identified as important determinants of JHSC effectiveness across various jurisdictions include adequate information, education and training; appropriate committee composition; senior management commitment to JHSCs; and especially a clear mandate with a broad scope and corresponding empowerment (through legislation and/or union presence). CONCLUSIONS Consistent empowerment mechanisms emerge as determinants of successful JHSCs across contexts despite few evidence-based details for best practice implementation. Intervention research is warranted.

Abstract The health service sector has a vital role to play in delivering human immunodeficiency virus (HIV) and tuberculosis (TB) prevention, treatment and care, yet evidence indicates that healthcare workers (HCWs) themselves lack adequate access to HIV and TB services. HCWs are also at increased risk from TB and other infectious diseases at work, and therefore accessing HIV services is particularly important. A systematic review was therefore conducted to inform the development of World Health Organization (WHO) guidelines to improve access to HIV and TB services, and specifically, to assess the evidence regarding providing such services through workplace-based programmes. We identified any study published since 1984 that addressed outcomes of interest as defined through multi-stakeholder consultations, and were related to workplace interventions in (1) the healthcare workplace and (2) any workplace that included HIV and/or TB diagnosis and/or treatment. Interventions focusing solely on primary prevention with no diagnostic or treatment services were excluded, as they were the subject of other guidelines. A minimum of two reviewers independently extracted data and assessed the articles against pre-set selection criteria; studies were also profiled and quality assessed by a minimum of two reviewers. Three studies met these criteria specifically for HCWs; all showed a preponderance of positive benefits, with minimal negative outcome. Seven studies met these criteria regarding workplace HIV and/or TB diagnosis and/or treatment from other sectors, public or private. Again, all showed positive results. The paucity of high-quality evidence in this field of research was itself an important finding, beckoning further research on workplace-based programmes for health workers. Nonetheless, while more well-designed intervention studies are definitely desirable, providing programmes for HCWs to obtain HIV and TB diagnosis and treatment at the workplace is supported by the literature and is consistent with the values of the stakeholders, justifying the WHO–International Labour Organization–UNAIDS guidelines that emerged.

Globalization has been accompanied by the rapid spread of infectious diseases, and further strain on working conditions for health workers globally. Post-SARS, Canadian occupational health and infection control researchers got together to study how to better protect health workers, and found that training was indeed perceived as key to a positive safety culture. This led to developing information and communication technology (ICT) tools. The research conducted also showed the need for better workplace inspections, so a workplace audit tool was also developed to supplement worker questionnaires and the ICT. When invited to join Ecuadorean colleagues to promote occupational health and infection control, these tools were collectively adapted and improved, including face-to-face as well as on-line problem-based learning scenarios. The South African government then invited the team to work with local colleagues to improve occupational health and infection control, resulting in an improved web-based health information system to track incidents, exposures, and occupational injury and diseases. As the H1N1 pandemic struck, the online infection control course was adapted and translated into Spanish, as was a novel skill-building learning tool that permits health workers to practice selecting personal protective equipment. This tool was originally developed in collaboration with the countries from the Caribbean region and the Pan American Health Organization (PAHO). Research from these experiences led to strengthened focus on building capacity of health and safety committees, and new modules are thus being created, informed by that work.The products developed have been widely heralded as innovative and interactive, leading to their inclusion into “toolkits” used internationally. The tools used in Canada were substantially improved from the collaborative adaptation process for South and Central America and South Africa. This international collaboration between occupational health and infection control researchers led to the improvement of the research framework and development of tools, guidelines and information systems. Furthermore, the research and knowledge-transfer experience highlighted the value of partnership amongst Northern and Southern researchers in terms of sharing resources, experiences and knowledge.

Academics from diverse disciplines are recognizing not only the procedural ethical issues involved in research, but also the complexity of everyday “micro” ethical issues that arise. While ethical guidelines are being developed for research in aboriginal populations and low-and-middle-income countries, multi-partnered research initiatives examining arts-based interventions to promote social change pose a unique set of ethical dilemmas not yet fully explored. Our research team, comprising health, education, and social scientists, critical theorists, artists and community-activists launched a five-year research partnership on arts-for-social change. Funded by the Social Science and Humanities Research Council in Canada and based in six universities, including over 40 community-based collaborators, and informed by five main field projects (circus with street youth, theatre by people with disabilities, dance for people with Parkinson’s disease, participatory theatre with refugees and artsinfused dialogue), we set out to synthesize existing knowledge and lessons we learned. We summarized these learnings into 12 key points for reflection, grouped into three categories: community-university partnership concerns (n = 3), dilemmas related to the arts (n = 5), and team issues (n = 4). In addition to addressing previous concerns outlined in the literature (e.g., related to consent, anonymity, dangerous emotional terrain, etc.), we identified power dynamics (visible and hidden) hindering meaningful participation of community partners and university-based teams that need to be addressed within a reflective critical framework of ethical practice. We present how our team has been addressing these issues, as examples of how such concerns could be approached in community-university partnerships in arts for social change.

Return to work policies and practices are, first and foremost, the products of the historical, economic, and political context within which they were formed. This chapter thus starts with a description of these “macrosystem” themes, providing a depiction of key historical events as well as the economic and political contexts that are relevant to return to work. The second part of this chapter discusses the mesosystem influences – consisting of the workplace, insurance, and healthcare system relationships – to explain how the interactions among stakeholders within the workplace and between the workplace and other key players impact return to work. The third part focuses on the role of the worker’s microsystem – the coworker and supervisor support for the individual worker. This chapter concludes by discussing the interplay between societal, workplace, and work unit factors, noting what can be done at each level to enhance successful return to work.
