Knowledge management in health: a systematic literature review

Knowledge has been used as a resource for intelligent and effective action planning in organizations. Interest in research on knowledge management processes has intensified in different areas. A systematic literature review was accomplished, based on the question: what are the contributions of Brazilian and international journal publications on knowledge management in health? The sample totaled 32 items that complied with the inclusion criteria. The results showed that 78% of journals that published on the theme are international, 77% of researchers work in higher education and 65% have a Ph.D. The texts gave rise to five thematic categories, mainly: development of knowledge management systems in health (37.5%), discussion of knowledge management application in health (28.1%) and nurses' function in knowledge management (18.7%).

The health impacts of windstorms: a systematic literature review

Introduction

This systematic literature review aims to identify documented impacts that windstorms have on human health. Windstorms occur frequently and some researchers have predicted an increase in severe gales in the future, resulting in an urgent need to understand the related patterns of morbidity and mortality.

Study design

Systematic literature review.

Methods

A systematic literature review of international evidence on the impacts of windstorms on human health was conducted in May 2012.

Results

This review of published evidence demonstrates that human health can be severely affected by windstorms. Direct effects occur during the impact phase of a storm, causing death and injury due to the force of the wind. Becoming airborne, being struck by flying debris or falling trees and road traffic accidents are the main dangers. Indirect effects, occurring during the pre- and post-impact phases of the storm, include falls, lacerations and puncture wounds, and occur when preparing for, or cleaning up after a storm. Power outages are a key issue and can lead to electrocution, fires and burns and carbon monoxide poisoning from gasoline powered electrical generators. Additionally, worsening of chronic illnesses due to lack of access to medical care or medication can occur. Other health impacts include infections and insect bites.

Conclusion

Public health advice can reduce morbidity and mortality from windstorms. Findings from this review will provide material for increased awareness and education amongst the public and healthcare professionals to prevent and prepare for these health impacts. Nevertheless, more research is needed to identify more specific patterns of health impacts and how these could be reduced in the future.     

Effectiveness of community health workers in Brazil: a systematic review

The objective of this study is to assess the effectiveness of community health workers (CHWs) in Brazil. This systematic review included all studies that sought to assess interventions involving CHWs. Despite the low quality of evidence for most outcomes, analysis of the 23 publications included often found benefit for CHW intervention, best documented for frequency of child weighing, prevalence of breast-feeding, and delayed introduction of bottle-feeding. These findings and the current major role CHWs play in Brazil suggest that clarifying the benefit of CHW actions across a broad range of health care interventions should be a major research priority.     

Describing reporting guidelines for health research: a systematic review

Objective

To describe the process of development, content, and methods of implementation of reporting guidelines for health research.

Study Design and Setting

A systematic review of publications describing health research reporting guidelines developed using consensus.

Results

Eighty-one reporting guidelines for health research were included in the review. The largest number of guidelines do not focus on a specific study type (n = 35; 43%), whereas those that do primarily refer to reporting of randomized controlled trials (n = 16; 35%). Most of the guidelines (n = 76; 94%) include a checklist of recommended reporting items, with a median of 21 checklist items (range: 5-64 items). Forty-seven (58%) reporting guidelines were classified as new guidance. Explanation documents were developed for 11 (14%) reporting guidelines. Reporting-guideline developers provided little information about the guideline development process. Developers of 50 (62%) reporting guidelines encouraged endorsement, most commonly by including guidelines in journal instructions to authors (n = 18; 36%).

Conclusions

Reporting-guideline developers need to endeavor to maximize the quality of their product. Recently developed guidance is likely to facilitate more robust guideline development. Journal editors can be more confident in endorsing reporting guidelines that have followed these approaches.     

Performance-based incentives and community health workers’ outputs,a systematic review

ObjectiveTo review the evidence on the impact on measurable outcomes of performance-based incentives for community health workers (CHWs) in low- and middle-income countries.MethodsWe conducted a systematic review of intervention studies published before November 2020 that evaluated the impact of financial and non-financial performance-based incentives for CHWs. Outcomes included patient health indicators; quality, utilization or delivery of health-care services; and CHW motivation or satisfaction. We assessed risk of bias for all included studies using the Cochrane tool. We based our narrative synthesis on a framework for measuring the performance of CHW programmes, comprising inputs, processes, performance outputs and health outcomes.FindingsTwo reviewers screened 2811 records; we included 12 studies, 11 of which were randomized controlled trials and one a non-randomized trial. We found that non-financial, publicly displayed recognition of CHWs’ efforts was effective in improved service delivery outcomes. While large financial incentives were more effective than small ones in bringing about improved performance, they often resulted in the reallocation of effort away from other, non-incentivized tasks. We found no studies that tested a combined package of financial and non-financial incentives. The rationale for the design of performance-based incentives or explanation of how incentives interacted with contextual factors were rarely reported.ConclusionFinancial performance-based incentives alone can improve CHW service delivery outcomes, but at the risk of unincentivized tasks being neglected. As calls to professionalize CHW programmes gain momentum, research that explores the interactions among different forms of incentives, context and sustainability is needed.     

系统综述的愿景: 优劣势分析

系统综述作为循证医学的核心方法,可向全面总结同一研究问题的所有证据,有助于临床医生、科研工作者和医疗卫生决策者在有限的时间里快速获取综合、精确、可靠的信息,使他们紧跟医学领域快速发展的步伐,拉近研究证据和医学实践的距离。然而,近年来人们对系统综述的质疑和批判不断。基于此,本文简要介绍了系统综述的起源和概念,详细阐述了系统综述的优势和局限性。最后,基于综述的应用和现状,对系统综述的未来作了展望。即使系统综述的方法学本身存在局限性,但仍是综合某一领域所有研究证据最权威的方法,因为我们目前没有更好的方法。如果系统地综合了所有研究的结果都是不可靠的,我们也没有理由说明其中的某个或某几个研究的结果就是公正无偏的。     

Physical activity during pregnancy and maternal-child health outcomes: a systematic literature review

A systematic literature review was conducted to investigate the effects of physical activity during pregnancy on selected maternal-child health outcomes. The search included articles published from 1980 to 2005 in the MEDLINE and LILACS databases using key words such as physical activity, physical exercise, pregnancy, and gestation. The methodological quality of 37 selected articles was evaluated. It appears to be a consensus that some light-to-moderate physical activity is not a risk factor and may even be considered a protective factor for some outcomes. However, some studies found an association between specific activities (e.g., climbing stairs or standing for long periods) and inadequate birth weight, prematurity, and miscarriage. Few studies found an association between physical activity and maternal weight gain, mode of delivery, or fetal development. Further research is needed to fill these gaps and provide guidelines on the intensity, duration, and frequency of physical activity during pregnancy.     

Evaluation of animal and public health surveillance systems: a systematic review

Disease surveillance programmes ought to be evaluated regularly to ensure they provide valuable information in an efficient manner. Evaluation of human and animal health surveillance programmes around the world is currently not standardized and therefore inconsistent. The aim of this systematic review was to review surveillance system attributes and the methods used for their assessment, together with the strengths and weaknesses of existing frameworks for evaluating surveillance in animal health, public health and allied disciplines. Information from 99 articles describing the evaluation of 101 surveillance systems was examined. A wide range of approaches for assessing 23 different system attributes was identified although most evaluations addressed only one or two attributes and comprehensive evaluations were uncommon. Surveillance objectives were often not stated in the articles reviewed and so the reasons for choosing certain attributes for assessment were not always apparent. This has the potential to introduce misleading results in surveillance evaluation. Due to the wide range of system attributes that may be assessed, methods should be explored which collapse these down into a small number of grouped characteristics by focusing on the relationships between attributes and their links to the objectives of the surveillance system and the evaluation. A generic and comprehensive evaluation framework could then be developed consisting of a limited number of common attributes together with several sets of secondary attributes which could be selected depending on the disease or range of diseases under surveillance and the purpose of the surveillance. Economic evaluation should be an integral part of the surveillance evaluation process. This would provide a significant benefit to decision-makers who often need to make choices based on limited or diminishing resources.     

Access control management in electronic health records: a systematic literature review

Objective

This study presents the results of a systematic literature review of aspects related to access control in electronic health records systems, wireless security and privacy and security training for users.

Methods

Information sources consisted of original articles found in Medline, ACM Digital Library, Wiley InterScience, IEEE Digital Library, Science@Direct, MetaPress, ERIC, CINAHL and Trip Database, published between January 2006 and January 2011. A total of 1,208 articles were extracted using a predefined search string and were reviewed by the authors. The final selection consisted of 24 articles.

Results

Of the selected articles, 21 dealt with access policies in electronic health records systems. Eleven articles discussed whether access to electronic health records should be granted by patients or by health organizations. Wireless environments were only considered in three articles. Finally, only four articles explicitly mentioned that technical training of staff and/or patients is required.

Conclusion

Role-based access control is the preferred mechanism to deploy access policy by the designers of electronic health records. In most systems, access control is managed by users and health professionals, which promotes patients’ right to control personal information. Finally, the security of wireless environments is not usually considered. However, one line of research is eHealth in mobile environments, called mHealth.     

Hazardous waste and health impact: a systematic review of the scientific literature

Waste is part of the agenda of the European Environment and Health Process and included among the topics of the Sixth Ministerial Conference on Environment and Health. Disposal and management of hazardous waste are worldwide challenges. We performed a systematic review to evaluate the evidence of the health impact of hazardous waste exposure, applying transparent and a priori defined methods. The following five steps, based on pre-defined systematic criteria, were applied. 1. Specify the research question, in terms of “Population-Exposure-Comparators-Outcomes” (PECO). Population: people living near hazardous waste sites; Exposure: exposure to hazardous waste; Comparators: all comparators; Outcomes: all diseases/health disorders. 2. Carry out the literature search, in Medline and EMBASE. 3. Select studies for inclusion: original epidemiological studies, published between 1999 and 2015, on populations residentially exposed to hazardous waste. 4. Assess the quality of selected studies, taking into account study design, exposure and outcome assessment, confounding control. 5. Rate the confidence in the body of evidence for each outcome taking into account the reliability of each study, the strength of the association and concordance of results.Fifty-seven papers of epidemiological investigations on the health status of populations living near hazardous waste sites were selected for the evidence evaluation. The association between 95 health outcomes (diseases and disorders) and residential exposure to hazardous waste sites was evaluated. Health effects of residential hazardous waste exposure, previously partially unrecognized, were highlighted. Sufficient evidence was found of association between exposure to oil industry waste that releases high concentrations of hydrogen sulphide and acute symptoms. The evidence of causal relationship with hazardous waste was defined as limited for: liver, bladder, breast and testis cancers, non-Hodgkin lymphoma, asthma, congenital anomalies overall and anomalies of the neural tube, urogenital, connective and musculoskeletal systems, low birth weight and pre-term birth; evidence was defined as inadequate for the other health outcomes. The results, although not conclusive, provide indications that more effective public health policies on hazardous waste management are urgently needed. International, national and local authorities should oppose and eliminate poor, outdated and illegal practices of waste disposal, including illegal transboundary trade, and increase support regulation and its enforcement.     

Health hazards from volcanic gases: a systematic literature review

Millions of people are potentially exposed to volcanic gases worldwide, and exposures may differ from those in anthropogenic air pollution. A systematic literature review found few primary studies relating to health hazards of volcanic gases. SO2 and acid aerosols from eruptions and degassing events were associated with respiratory morbidity and mortality but not childhood asthma prevalence or lung function decrements. Accumulations of H2S and CO2 from volcanic and geothermal sources have caused fatalities from asphyxiation. Chronic exposure to H2S in geothermal areas was associated with increases in nervous system and respiratory diseases. Some impacts were on a large scale, affecting several countries (e.g., Laki fissure eruption in Iceland in 1783-4). No studies on health effects of volcanic releases of halogen gases or metal vapors were located. More high quality collaborative studies involving volcanologists and epidemiologists are recommended.     

Multidisciplinary team,working with elderly persons living in the community: a systematic literature review

This paper suggests and discusses a methodological approach that aims to facilitate the inclusion of people with dementia in research where the ambition is to better understand their experiences. People with dementia have commonly not been included as informants in research as their cognitive deficits have been regarded as a hindrance. Moreover, in the qualitative research tradition, most inquiries rely on data obtained from interviews, thereby requiring communication and verbal skills, which are skills that are affected early in the cause of dementia. Consequently, the considerably under-researched area of how dementia is experienced and managed from the perspective of those afflicted has long been put aside. This paper suggests that a combination of qualitative observations and adapted interviews may make it possible for people with dementia to participate as research informants. Issues concerned with creating a relationship with informants with dementia and helping them to elicit their experiences are elaborated and discussed. Some suggestions are made concerning how the context can be used for this intent, and how the observations and interviews can be adapted to the informants with dementia.     

Improving health outcomes through community empowerment: a review of the literature

This paper reviews the literature on how empowerment can lead to an improvement in the health status of an individual, group, or community. There is a broad body of literature on empowerment, and this review has been designed to identify material, particularly case studies, that can be included within the following 'empowerment domains': Participation; Community-based organizations; Local leadership; Resource mobilization; Asking 'why'; Assessment of problems; Links with other people and organizations; Role of outside agents; and Programme management. The paper discusses the results of the literature review and provides examples, from both developed and developing countries, of how each of the 'empowerment domains' has led to an improvement in health outcomes. The results of the review should be of interest to the planners and practitioners of health, population and nutrition programmes that have a particular focus on empowerment.     

Neighbourhood community life and health: A systematic review of reviews

Neighbourhood community life has been widely recognized as an important determinant of population health. This systematic review of reviews provides an overview of the evidence for the ecological correlation between neighbourhood community life and population health. Nine databases were searched from 2008 to 2018 in order to identify systematic reviews of studies examining the association between neighbourhood community life and population health in urban neighbourhoods within the Organisation for Economic Co-operation and Development countries. Two reviewers completed selection and data extraction, then assessed the methodological quality of reviews using the Measurement Tool to Assess Systematic Reviews. We identified three high quality reviews and five of moderate quality. The reviews vary in quality of methodology, concepts, and measures. Most of the reviews examined the influence of social cohesion, social capital, and social interactions on health. Reviews found evidence supporting a consistently favourable correlation between social cohesion and physical activity, as well as a favourable trend in the relationship between social cohesion and healthy weight. They also found evidence of a favourable trend in the correlation between social capital and healthy weight. Reviews identified studies supporting a consistently favourable correlation between social interaction and depression. We identify evidence of a positive association between neighbourhood community life and several population health outcomes. Future research should define and conceptualize neighbourhood community life factors and health indicators to improve the comparison between studies and the process of evidence synthesis. This will also enable policy makers to take appropriate decisions.     

Reducing work related psychological ill health and sickness absence: a systematic literature review

A literature review revealed the following: key work factors associated with psychological ill health and sickness absence in staff were long hours worked, work overload and pressure, and the effects of these on personal lives; lack of control over work; lack of participation in decision making; poor social support; and unclear management and work role. There was some evidence that sickness absence was associated with poor management style. Successful interventions that improved psychological health and levels of sickness absence used training and organisational approaches to increase participation in decision making and problem solving, increase support and feedback, and improve communication. It is concluded that many of the work related variables associated with high levels of psychological ill health are potentially amenable to change. This is shown in intervention studies that have successfully improved psychological health and reduced sickness absence.     

Coordinated school health programs and academic achievement: a systematic review of the literature

BACKGROUND: Few evaluations of school health programs measure academic outcomes. K-12 education needs evidence for academic achievement to implement school programs. This article presents a systematic review of the literature to examine evidence that school health programs aligned with the Coordinated School Health Program (CSHP) model improve academic success. METHODS: A multidisciplinary panel of health researchers searched the literature related to academic achievement and elements of the CSHP model (health services, counseling/social services, nutrition services, health promotion for staff, parent/family/community involvement, healthy school environment, physical education, and health education) to identify scientifically rigorous studies of interventions. Study designs were classified according to the analytic framework provided in the Guide developed by the Community Preventive Services Task Force. RESULTS: The strongest evidence from scientifically rigorous evaluations exists for a positive effect on some academic outcomes from school health programs for asthmatic children that incorporate health education and parental involvement. Strong evidence also exists for a lack of negative effects of physical education programs on academic outcomes. Limited evidence from scientifically rigorous evaluations support the effect of nutrition services, health services, and mental health programs, but no such evidence is found in the literature to support the effect of staff health promotion programs or school environment interventions on academic outcomes. CONCLUSIONS: Scientifically rigorous evaluation of school health programs is challenging to conduct due to issues related to sample size, recruitment, random assignment to condition, implementation fidelity, costs, and adequate follow-up time. However, school health programs hold promise for improving academic outcomes for children.
