Occupational accidents and the use of PPE: a global meta-analysis.

Occupational accidents, despite continuous safety updates, are still a scourge in the occupational and forensic spheres, constituting, among other things, the subject of a large share of litigation. Demographic data can help to understand the areas where the application of health surveillance is lacking. This meta-analysis sets out to analyse data from studies on accidents at work, focusing on the correlation between the areas in which accidents occur and whether or not personal safety equipment is used, in relation to the different regulations in force. For the selection of the data, a systematic review was carried out according to the PRISMA guidelines, with the primary objective of identifying the trend of occupational accidents in specific geographical areas, which differ in terms of the attention paid to preventive aspects. The data we highlighted showed, regarding the type of accident, substantial differences between low-income countries and industrialised countries (stratified according to the Human Development Index) and, an overall indifference as to whether or not individual safety devices were used, revealing that, despite the continuous normative evolution in the field of safety at work, even today, the investigative data on the actual application of the regulations, during accidents at work, is underestimated and little researched.

Systemic barriers to reporting work injuries and illnesses in contexts of language barriers.

BACKGROUND: Workers who experience language barriers are at increased risk of work-related injuries and illnesses and face difficulties reporting these health problems to their employer and workers' compensation. In the existing occupational health and safety literature, however, such challenges are often framed in individual-level terms. We identify systemic barriers to reporting among injured workers who experience language barriers within the varying contexts of Ontario and Quebec, Canada. METHODS: This study merges data from two qualitative studies that investigated experiences with workers' compensation and return-to-work, respectively, for injured workers who experience language barriers. We conducted semi-structured interviews with 39 workers and 70 stakeholders in Ontario and Quebec. Audio recordings were transcribed and coded using NVivo software. The data was analysed thematically and iteratively. RESULTS: Almost all workers (34/39) had filed a claim, though most had initially delayed reporting their injuries or illnesses to their employer or to workers' compensation. Workers faced several obstacles to reporting, including confusion surrounding the cause and severity of injuries and illnesses; lack of information, misinformation, and disinformation about workers' compensation; difficulties accessing and interacting with care providers; fear and insecurity linked to precarity; claim suppression by employers; negative perceptions of, and experiences with, workers' compensation; and lack of supports. Language barriers amplified each of these difficulties, resulting in significant negative impacts in economic, health, and claim areas. CONCLUSION: Improving the linguistic and cultural competence of organizations and their representatives is insufficient to address under-reporting among workers who experience language barriers. Efforts to improve timely reporting must tackle the policies and practices that motivate and enable under-reporting for workers, physicians, and employers.

The prevalence, seriousness, and causes of teenage work accidents: A gender difference?

BACKGROUND: Teenage workers are prone to a higher injury risk than adult workers, and adult men are prone to a higher risk of work injuries than adult women. OBJECTIVES: This study aims to examine whether gender differences exist in teenage work accidents, the level of the accidents, their causes, and the types of the injuries. METHODS: A survey was sent to a sample of 2,800 13-19-year-olds, randomly selected from Registers Iceland. The response rate was 48.6%. A chi-square test, CI 95%, was applied to measure gender differences. RESULTS: In total, 16.3%of the respondents had at least one work accident, and 1.2%, an accident that lead to more than one week's absence from work. No gender differences were observed in the level of the accidents, but appeared in the types of injuries and their causes. Cuts were the most common injuries of the boys, but burns of the girls. Bone fractures were the most serious injuries of the boys, but sprains of the girls. CONCLUSION: Work accidents among teenagers are a particular threat to public health. Therefore, all stakeholders need to work together to prevent teenage work accidents in the future; and to keep in mind the gender diversity of the group.

The Contribution of Occupation-Specific Factors to the Deaths of Despair, Massachusetts, 2005-2015.

OBJECTIVES: In the USA, deaths from poisonings (especially opioids), suicides, and alcoholic liver disease, collectively referred to as 'deaths of despair', have been increasing rapidly over the past two decades. The risk of deaths from these causes is known to be higher among certain occupations. It may be that specific exposures and experiences of workers in these occupations explain these differences in risk. This study sought to determine whether differences in the risk of deaths of despair were associated with rate of occupational injuries and illnesses, job insecurity, and temporal changes in employment in non-standard work arrangements. METHODS: Usual occupation information was collected from death certificates of Massachusetts residents aged 16-64 with relevant causes of death between 2005 and 2015. These data were combined with occupation-level data about occupational injuries and illnesses, job insecurity, and non-standard work arrangements. We calculated occupation-specific mortality rates for deaths of despair, categorized by occupational injury and illnesses rates and job insecurity. We calculated trends in mortality according to changes in non-standard work arrangements. RESULTS: Workers in occupations with higher injury and illnesses rates and more job insecurity had higher rates of deaths of despair, especially opioid-related deaths. Rates of deaths of despair increased most rapidly for occupations with increasing prevalence of workers employed in non-standard work arrangements. CONCLUSIONS: The findings suggest occupational factors that may contribute to the risk of deaths of despair. Future studies should examine these factors with individual-level data. In the meantime, efforts should be made to address these factors, which also represent known or suspected hazards for other adverse health outcomes.

Workplace Safety: A Strategy for Enterprise Risk Management.

Background: Injury and illness incidence rates continue to be higher in healthcare facilities than in the manufacturing environment despite improvement efforts implemented by various organizations. The prevention of workplace injury and illness is a challenge for facilities due to reasons including exposure to body fluids, infectious diseases, and patient handling activities. The purpose of this project was to reduce workplace safety-related incidents and prevent employee injuries through leadership involvement in employment of preventive, directive, and corrective controls. Methods: A tertiary medical center in California experienced 114 accepted injury claims in 1 year. As a response to the problem, the medical center developed a safety management system consisting of a process for engagement between leadership and staff members/employees to increase accountability and reduce injury risks. Findings: The medical center achieved a 59% reduction from 114 to 67 injury claims over a period of 2 years and a two-point increase in engagement scores from both leaders and staff members. Conclusion/Application to Practice: The development of a safety culture starts with leadership behavior, establishment of clear safety processes, and hazard mitigation activities. Workplace safety is a shared responsibility between frontline staff managers and leadership within an organization. Senior leaders must serve as role models to promote a speak-up culture to support safe work practices.

Need and Capacity of a Toolkit for Occupational Health Nurses to Promote a New or Enhanced Drug-Free Workplace Program.

Background: A drug-free workplace program (DFWP) has been shown to be effective in reducing workers' drug misuse. The purpose of this project was to determine the need and capacity for a new or enhanced DFWP in a large health system. If determined to be needed, the next step would be to develop, implement, and evaluate a toolkit to assist occupational health nurses to promote a new or enhanced DFWP. Methods: A strategic prevention framework was used to assess the need and capacity for a toolkit to prepare occupational health nurses to promote a new or enhanced DFWP. The project was conducted in the occupational health services department at a large health system in the Midwest U.S. occupational health nurses and employee assistance counselors in the hospital system completed a survey assessing the need and capacity for a new or enhanced DFWP. Findings: A gap was identified in the perceived effectiveness of training about DFWP and current DFWP components. The findings reflect the need and capacity for a DFWP toolkit. Optimally, a DFWP toolkit would include evidence-based drug and alcohol screening tools. We found that a toolkit for occupational health nurses to promote a new or enhanced DFWP in the project site was warranted. Conclusion/Application to practice: A DFWP can be an effective method of promoting workplace health and safety. Occupational health nurses can contact state and national representatives to encourage monitoring of drug-related work injuries to provide evidence to influence health policies to support effective DFWPs.

Group-Based Acceptance and Commitment Therapy for Nurses and Nurse Aides Working in Long-Term Care Residential Settings.

Objectives: Nurses and nurse aides experience high rates of physical injury, assault, and abuse compared to other occupations. They also frequently have intersectional identities with other groups that experience higher rates of mental and physical health challenges and problems. In addition to belonging to these multiple vulnerable populations, nurses and nurse aides experience high levels of work stress and burnout. These variables are risk factors for injuries associated with lifting and transferring, as well as assault from residents. Given the focus on present moment awareness, commitment to values, and responding flexibly in difficult situations, Acceptance and Commitment Therapy (ACT) may be an effective approach for this population. Design: Participants were randomly assigned to either the ACT group condition or a wait-list control condition. Participants completed baseline and one-month follow-up outcome measures. Setting/Location: The interventions were provided at participant work sites (nursing homes and assisted living facilities) that were located in multiple locations across Northern Ohio. Subjects: Seventy-one nurses and nurse aides participated in the study. Of these, 37 were randomly assigned to the ACT group intervention and 34 were assigned to the wait-list control group. Intervention: A two-session group-based ACT intervention. Each session was 2.5 hours long and spaced one-week apart. The intervention topics included acceptance, mindfulness, psychological flexibility, willingness to experience discomfort, present-moment focus, self-as-context, values identification, and values-congruent committed action. Outcome measures: Days missed due to injury, frequency of work-based injuries, musculoskeletal complaints, mental health symptoms, and overall satisfaction with the intervention. Results: Participants in the ACT group reported significantly fewer days missed due to injury and a significant reduction in mental health symptoms compared to the control group. Participants in the ACT group rated the intervention very favorably. Conclusion: A group-based ACT intervention can promote improvements in well-being for nurses and nurse aides working in long-term care settings. Further research in this area would benefit from conducting group-based ACT interventions at different organizational levels.

Risk of work injury among adolescent students from single and partnered parent families.

BACKGROUND: Parental involvement in keeping their children safe at work has been examined in a handful of studies, with mixed results. Evidence has suggested that non-work injury risk is higher among children from single-parent families, but little is known about their risk for work-related injuries. METHODS: Five survey cycles of the Canadian Community Health Survey were pooled to create a nationally representative sample of employed 15-19-year old students (N = 16,620). Multivariable logistic regression estimated the association between family status and work injury. RESULTS: Risk of work-related repetitive strains (OR:1.24, 95%CI: 0.69-2.22) did not differ by family type. However, children of single parents were less likely to sustain a work injury receiving immediate medical care (OR:0.43, 95%CI: 0.19-0.96). CONCLUSION: Despite advantages and disadvantages related to family types, there is no evidence that work-related injury risk among adolescents from single parent families is greater than that of partnered-parent families.

Psychosocial safety climate, emotional exhaustion, and work injuries in healthcare workplaces.

Preventing work injuries requires a clear understanding of how they occur, how they are recorded, and the accuracy of injury surveillance. Our innovation was to examine how psychosocial safety climate (PSC) influences the development of reported and unreported physical and psychological workplace injuries beyond (physical) safety climate, via the erosion of psychological health (emotional exhaustion). Self-report data (T2, 2013) from 214 hospital employees (18 teams) were linked at the team level to the hospital workplace injury register (T1, 2012; T2, 2013; and T3, 2014). Concordance between survey-reported and registered injury rates was low (36%), indicating that many injuries go unreported. Safety climate was the strongest predictor of T2 registered injury rates (controlling for T1); PSC and emotional exhaustion also played a role. Emotional exhaustion was the strongest predictor of survey-reported total injuries and underreporting. Multilevel analysis showed that low PSC, emanating from senior managers and transmitted through teams, was the origin of psychological health erosion (i.e., low emotional exhaustion), which culminated in greater self-reported work injuries and injury underreporting (both physical and psychological). These results underscore the need to consider, in theory and practice, a dual physical-psychosocial safety explanation of injury events and a psychosocial explanation of injury underreporting.

Chronic pain among public safety personnel in Canada.

Background: Chronic pain is highly prevalent in the general population and may be even higher among public safety personnel (PSP; e.g., correctional officers, dispatchers, firefighters, paramedics, police). Comprehensive data on chronic pain among diverse Canadian PSP are relatively sparse. Aims: The current study was designed to provide initial estimates of chronic pain frequency and severity among Canadian PSP. Methods: Estimates of chronic pain frequency and severity (i.e., intensity and duration) at different bodily locations were derived from self-reported data collected through an online survey. Participants included 5093 PSP (32.5% women) grouped into six categories (i.e., call center operators/dispatchers, correctional officers, firefighters, municipal/provincial police, paramedics, Royal Canadian Mounted Police [RCMP]). Results: Substantial proportions of participants reported chronic pain, with estimates ranging from 35.3% to 45.4% across the diverse PSP categories. Across PSP categories, chronic lower back pain was the most prevalent. For some pain locations, firefighters and municipal/provincial police reported lower prevalence, but paramedics reported lower intensity, and duration, than some other PSP groups. Over 50% of RCMP and paramedics reporting chronic pain indicated that the pain was associated with an injury related to active duty. Conclusions: Discrepancies emerged across PSP members with respect to prevalence, location, and severity. The current data suggest that additional resources and research are necessary to mitigate the development and maintenance of distressing or disabling chronic pain for Canadian PSP.

Contexte : La prévalence de la douleur chronique est élevée parmi la population en général et pourrait être encore plus élevée chez le personnel de la sécurité publique (ex.: agents correctionnels, répartiteurs, pompiers, ambulanciers, policiers). Il y a relativement peu de données exhaustives sur la douleur chronique chez le personnel de sécurité publique canadien.But : Cette étude visait à estimer la fréquence et la gravité de la douleur chronique chez le personnel de sécurité publique canadien.Méthodes : Des estimations de la fréquence et de la gravité de la douleur chronique (i.e. intensité et durée) à différents endroits du corps ont été tirées de données autodéclarées receuillies par le truchement d'un questionnaire en ligne. Les 5 093 participants (32,5 % de femmes) ont été regroupés en six catégories (i.e. opérateurs et répartiteurs en centre d'appel, agents correctionnels, pompiers, policiers au niveau municipal ou provincial, ambulanciers, Gendarmerie royale du Canada.)Résultats : Une proportion importante de participants a déclaré souffrir de douleur chronique, avec des estimations allant de 35,3 % à 45,4 % pour toutes les catégories de personnel de sécurité. La douleur au bas du dos présentait la prévalence la plus élevée dans toutes les catégories de personnel de sécurité. Les ambulanciers ont déclaré une plus faible prévalence de l'intensité et de la durée de la douleur à ressentie à certains endroits, comparativement aux autres groupes de personnel de la santé publique. Plus de 50 % des agents de la Gendarmerie royale du Canada et des ambulanciers qui ont déclaré souffrir de douleur chronique ont affirmé que la douleur était associée à une blessure subie pendant qu'ils étaient en service.Conclusions : Des différences ont été relevées entre les membres du personnel de la sécurité publique en ce qui concerne la prévalence, la localisation et la gravité de la douleur. Les données actuelles suggèrent que des ressources et des études additionnelles sont nécessaires pour atténuer l'apparition et la persistance de la douleur chronique éprouvante ou invalidante chez le personnel de la sécurité publique canadien.

Effect of Work Injuries Rehabilitation Investigate System on Early Intervention of Hand Trauma Rehabilitation / 中国康复理论与实践

Objective To establish a management system to promote early rehabilitation for work injured patients. Methods The 2015 hospitalized patients were set as control group (n=16,635), and the 2016 hospitalized patients were set as observation group (n=15,372). The control group was hospitalized for injury data collection surveys and was not implemented systematic rehabilitation propaganda, rehabilita-tion assessment and rehabilitation guidance. However, the observation group hospitalized after establishment of the Work Injuries Rehabilita-tion Investigation System and accepted work injuries rehabilitation intervention, such as rehabilitation propaganda, rehabilitation assessment and rehabilitation guidance. The changes of hand trauma rehabilitation indicators were compared between two groups. Results The rate of work injuries rehabilitation intervention was 80.6%in the observation group. In the observation group, the proportion of the patients who re-ceived early rehabilitation treatment in the designated hospital (56.8%) was significantly higher than that of the control group (17.0%) (χ2=2603.683, P<0.001);the proportion of injured patients who were admitted to the designated work injuries rehabilitation institutions (9.4%) was higher than that of the control group (4.3%) (χ2=285.906, P<0.001). The proportion of patients evaluated as disability in the observation group (17.4%) was significantly less than that of the control group (26.3%) (χ2=235.327, P<0.001). The disability score was significantly lower in the observation group (6.23±1.29) than in the control group (8.26±1.16) (t=68.371, P<0.001). Conclusion The Work Injuries Reha-bilitation Investigation System can promote the early rehabilitation for the hand trauma patients in the designated hospital for work injuries, improve the proportion of hand trauma patients to enter the designated work injuries rehabilitation institutions to receive rehabilitation treat-ment, reduce the proportion of disabled persons, and reduce the degree of disability, effectively promote the overall recovery of patients with hand trauma.

Occupational Therapy Practitioners with Occupational Musculoskeletal Injuries: Prevalence and Risk Factors.

PURPOSE: The purpose of this study was to examine the prevalence and risk factors of occupational musculoskeletal injuries (OMIs) among occupational therapy practitioners over a 12-month period. METHOD: A self-administered questionnaire mailed to 500 randomly selected practicing occupational therapists (OTs) and occupational therapy assistants (OTAs) living in the state of Texas. RESULTS: A response rate of 38 % was attained with 192 questionnaires returned. In a 12-months working period, 23 % of occupational therapy practitioners experienced musculoskeletal injuries. Muscle strain (52 %) was most reported injury and lower back (32 %) was most injured body part. Years of practicing experience (t = 2.83, p = 0.01), and age x(2)(2, N = 192) = 8.28, p = 0.02 were found as significant factors associated with injuries among OTAs. No factors were significantly associated with injuries among OTs. CONCLUSION: Patient handling was the primary factor associated with injuries. Also, minimal experience and older age were concluded as risk factors that might contribute to OMIs.

Safe patient handling and movement: a literature review.

PURPOSE: Musculoskeletal disorders (MSD) as a result of patient handling tasks occur at high rates for nursing staff and other patient care providers. Patient care providers perform high-risk patient handling tasks including lifting, transferring, ambulating, and repositioning patients. Continuous performance of these tasks places a patient care provider at risk for development of a MSD. MSDs affect a healthcare organization financially and impact the core of a hospital-the health of the workforce. The purpose of this research was to study the impact of a safe patient handling and movement program on healthcare worker injury, costs and job satisfaction. METHODS: A critical review of the safe patient handling literature was conducted. FINDINGS: A safe patient handling and movement (SPHM) program decreases overall work injury costs and improves healthcare worker job satisfaction. CONCLUSIONS AND CLINICAL RELEVANCE: Reduced work injuries, decreased injury costs, improved patient outcomes validated in research and employees feeling the support of their employer all contribute to a program that moves an organization toward a culture of safety.

A utilização de serviços de saúde por acidentados de trabalho / Health services utilization by occupational injured workers

Neste estudo descrevem-se as características da utilização de serviços de saúde por trabalhadores que sofreram acidentes de trabalho. Os dados provêm das três primeiras fases de um estudo de coorte de base comunitária sobre saúde e trabalho, iniciado no ano 2000, e conduzido com todos os trabalhadores de 2.512 famílias selecionadas por amostragem aleatória de conglomerado, de estágio único, residentes na cidade de Salvador, Bahia. Entrevistas individuais foram empregadas para a coleta de dados. Nesta pesquisa analisaram-se os trabalhadores (n = 628) que referiram ter sofrido acidente de trabalho nos 12 meses antes da entrevista. Observou-se que cerca de metade dos casos de acidentes recebeu primeiros socorros e tratamento médico. A maioria (71%) foi atendida em unidades do SUS. Cerca de 15% tiveram o atendimento pago por planos de saúde privados. Observou-se também que a maioria referiu alta satisfação com o atendimento, tanto em serviços públicos como privados. Entre os usuários do SUS, predominaram os trabalhadores sem carteira assinada, mas trabalhadores segurados também utilizaram os serviços públicos em sua maioria. Concluiu-se que o SUS tem expressiva participação no atendimento de acidentados do trabalho, independentemente da condição de cobertura por planos de saúde.

This study describes the characteristics of health services utilization by workers reporting work-related injuries. Data comes from the three first phases of a community-based cohort study about health and work that started in the year 2000, carried out with all workers from 2,512 families living in the city of Salvador, Bahia, that were selected by one-stage cluster area random sampling. Individual interviews were used for data collection. In this study, cases of work injuries reported during the 12 months before the interview (n=628) are analyzed. The majority (71.0%) of injured workers received medical treatment in facilities from the Unified Health System, SUS, a public health care system of universal coverage. Around 15% received treatment from private health insurance plans. Among SUS customers most workers have no formal job contracts, although insured workers also utilized public health care services. In sum, the SUS has expressive participation in the health care of injured workers independently of their entitlement for private health care.

Estudo epidemiologico dos coletores de lixo seletivo / Epidemiologic study of the selective garbage collectors

O artigo aborda epidemiologicamente o perfil dos coletores de lixo seletivo e descreve as lesões musculares e acidentes de trabalho mais freqüentes. Este estudo transversal foi desenvolvido com duas empresas (denominadas como empresa A e empresa B), em Porto Alegre, selecionando-se 50 funcionários aleatoriamente (presentes e aptos nos dias das entrevistas para a pesquisa) e aos quais foi aplicado um questionário. A Média de idade da amostra foi de 34 e 22 anos para a empresa A e B, respectivamente. Cerca de 66% dos funcionários da empresa B trabalham a menos de 5 anos na companhia, ao passo que 95% dos funcionários da empresa A trabalham há mais de 5 anos. O índice de lesões entre as duas empresas é alta 90% e 46,6% para empresas A e B, respectivamente. Lesões são mais comuns nos membros inferiores, seguidas pelas lesões dos membros superiores e da coluna. Ambas as empresas apresentavam deficiência do uso de equipamentos de proteção, sendo estes praticamente ignorados pelos funcionários, embora de uso obrigatório. As avaliações médicas são realizadas esporadicamente, sem acompanhamento regular. Ambas as empresas apresentam altos índices de leões em geral, sendo as lesões de membros inferiores mais comuns. Também são altos os índices de cortes e outros pequenos ferimentos, provavelmente pelo não uso de equipamentos de proteção obrigatórios.

Study the epidemiological profile of selective garbage collectors and describe the major muscle lesions and work acidents. Material and techniques this was a transversal study comparing the employees of the two principal companies who collects selective garbaje at Porto Alegre city, symbolized in this study as company A and company B. We applied a questionnaire randomly for 50 workers of the two companies. The mean age was 34 and 22 years old for company A and B respectively. Around sixty six percente of worker at company B have les than 5 years of experience at the job, comparing with the 95% of the employees of the company A who have more than 5 years at the job. The lesions indices are high at the two companies, 90 and 46,% for company A and B, respectively. The most common injuries were in inferior limbs, followed by upper limbs and column. Both the companies lack the do use of protection equipament in their workers, despite the obrigatory use in the work legislation. Medical evaluations are not regular. Both companies have a elevated percentage on injuries at work in general, being inferior limbs the most common ones. They also presented elevated indices of cuts and other small bruises, probably because of the no use of the obrigatory protection equipament.

Los accidentes de trabajo en Mexico: una nueva visión sobre salud laboral / The accidents of work in Mexico: a vision new labor health

Se estudian los accidentes de trabajo de una zona manufacturera en la ciudad de Mexico, atendidos por el Instituto Mexicano del Seguro Social (IMSS). Se analizaron 4.154 accidentes ocurridos en 42.748 trabajadores. El 95 por ciento de ellos ocasionó una incapacidad temporal, 2 por ciento generó algún grado de incapacidad permanente. Para el sector de la manufactura de Naucalpan se presentó una tasa de 7,26 por ciento trabajadores, superior a la media nacional de 6,28. Los datos permiten apreciar el papel de algunas variables sociedemográficas y laborales. Entre otros aspectos destaca la inserción de la mujer, 34 por ciento de la fuerza de trabajo. Las tasas son de 8.5 para los hombres y 4,6 para las mujeres (RR 1,84), pero por otra parte, la gravedad de los accidentes es similar en ambos sexos, 17,2 y 16,1 días de incapacidad por accidente respectivamente. Conforme aumenta la edad en los hombres, la frecuencia de accidentes disminuye pero la gravedad aumenta, mientras que en las mujeres se presenta un incremento de la frecuencia hacia los 40 años. Se encontró también una gran diversidad en la incidencia y la gravedad al comparar los grupos industriales. En las ramas de mayor accidentabilidad tienen una mayor presencia los varones. En otras, hombres y mujeres se accidentan de manera similar. Asímismo la experiencia laboral, evaluada según años de afiliación al IMSS no parece tener mayor peso. La información también se analizó por tipo diagnóstico y factores asociados al accidente, entre ellos se identificaron aspectos probablemente asociados a la organización del trabajo(AU)

Injuries resulting from work accidents among industrial workers attended by the social security system, Instituto Mexicano del Seguro Social (IMSS), in a manufacturers area of Mexico city were studied. There were analyzed 4,154 injuries occurred in 42,748 workers. The 95 % of those injuries caused a temporal incapacity, the 2 % caused permanent incapacity in some extent. For the Naucalpan manufacturer area, the was a rate of 7,26 in a hundred workers, rate which is superior to the national media of 6,28. Data allows to appreciate the roll of some other aspects, women introduction to work, which is the 34 %, is outstanding. The rates are: 8,5 for men and 4,6 for women )RR 1,84), but in the other hand, the severity of injuries is similar for both sexes, 17,2 and 16,1 days out of work due to accidents, respectively. As men grow older, frequency in accident decreases, but become more severe, while in women there is an increase in frequency around 0 years. It was also found a great diversity in the incidence and seriousness when comparing the industrial groups. In branches of greater accidents there are more among men, in others, men and women have accidents in the same way. Also, the working experience, evaluated according to years of affiliation to the IMSS seems not to have any great meaning. The information was also analyzed by kind of diagnosis and associated facts with the accident, among them factors, probably associated to work organization were identified(AU)
