Effect of professional certification on employees' return-to-work rate after occupational injuries in Korea: focusing on vulnerable groups

BACKGROUND@#One effective way to improve return-to-work (RTW) performance may be to convince the employer that the worker has the necessary skills. The aim of this paper is to investigate the effect of having a professional certification among workers injured in occupational injuries on their return to work.@*METHODS@#The Panel Study of Workers' Compensation Insurance (PSWCI) targets workers who completed medical care in 2012 after an occupational injury. The study population (n = 2000) was stratified by gender, age, region, disability grade, and rehabilitation service use. A total of 1458 workers were finally selected for this study. The effect of having a certification on RTW status was calculated with an odds ratio and 95% confidence intervals using binomial and multinomial logistic regression analyses. In the binomial logistic regression analysis, the RTW group was made up as a combination of the return to original work and the reemployment groups.@*RESULTS@#The ORs of RTW among those with a certification compared to those without certification were 1.38 (1.16-1.65) in Model 1, 1.25 (1.05-1.50) in Model 2, and 1.22 (1.01-1.47) in Model 3. Among female workers with a certification, the OR of RTW was 4.60 (2.68-7.91), that of return to original work was 3.21 (1.74-5.91), and that of reemployment was 5.85 (3.34-10.27). Among daily workers with a certification, the OR of RTW was 1.32 (1.03-1.69) and that of reemployment was 1.37 (1.07-1.76).@*CONCLUSION@#In conclusion, injured workers with a certification generally had a higher RTW rate. In particular, the RTW rate was higher among female workers and daily workers with a certification than among those without.

Quais pessoas com paraplegia traumática voltam a trabalhar? / Which people with traumatic paraplegia return to work?

Resumo Pesquisa objetivou investigar os fatores que interferem no retorno ao trabalho em indivíduos com paraplegia traumática e caracterizar o trabalho posterior à lesão, por meio de estudo epidemiológico do tipo transversal, sem inferência estatística. Participaram da pesquisa pacientes internados no Programa de Lesão Medular do Hospital Sarah de Reabilitação, Salvador. A análise descritiva usou média e desvio-padrão para variáveis contínuas e proporções para variáveis categóricas. Houve predomínio de homens entre os 42 pacientes entrevistados; a idade média foi de 36 anos. A escolaridade média foi de 9 anos. Retornaram ao trabalho 22 entrevistados, 21 deles inseridos no mercado de trabalho informal. A média de tempo para voltar a trabalhar foi de 3 anos. Principais motivos para voltar a trabalhar: necessidade de dinheiro, satisfação pessoal e contato com outras pessoas. O retorno ao trabalho mostra-se, neste estudo, relevante para o adulto com lesão medular, proporcionando-lhe maior rendimento e melhor qualidade de vida. Evidenciamos a importância de maior grau de escolaridade para o retorno ao trabalho bem sucedido. Portanto, é preciso aprimorar o processo de retorno ao trabalho, a qualificação e a reabilitação profissional desse trabalhador.

Abstract This research aimed to investigate the factors that affect the return to work of individuals with traumatic paraplegia and to characterize post-injury work by means of a cross-sectional epidemiological study without statistical inference. The participants were patients at the Spinal Cord Injury Program of the Sarah Rehabilitation Hospital, Salvador, Brazil. The descriptive analysis used mean and standard deviation for continuous variables and proportions for categorical variables. Male predominated among the 42 respondents, with a mean age of 36 years. Mean schooling years was 9 years. Twenty-two respondents returned to work, 21 of which were in the informal labor market. Mean time to return to work was 3 years. The main reasons for returning to work were need for money, personal satisfaction and contact with other people. In this study, returning to work is relevant for adults with spinal cord injury, providing them with higher income and better quality of life. We also noted the importance of higher education level for the successful return to work. Therefore, it is necessary to improve the return to work process, the qualification and professional rehabilitation of these workers.

Personality changes and return to work after severe traumatic brain injury: a prospective study

Objective: To evaluate predictors of non-return to work (nRTW) among social, demographic, clinical, and psychiatric variables after severe traumatic brain injury (TBI) in a cohort of Brazilian patients. Methods: Prospective study. Forty-three community-dwelling individuals treated at a Level I trauma center at the time of TBI were evaluated 18 months after trauma. Measures included DSM-IV-TR criteria for personality changes after TBI and Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) to assess psychiatric diagnosis. Hospitalization variables included Glasgow Coma Scale scores, pupil examination findings, associated limb trauma, Marshall computed tomography classification, and blood glucose levels. Results: After multiple logistic regression analysis, only the diagnosis of personality changes was found to be independently associated with nRTW, with an adjusted odds ratio of 10.92 (p = 0.02, 95% confidence interval 1.41-84.28). Conclusions: In this study, personality changes were an independent predictor of nRTW after severe TBI. Ways to predict risk factors associated with personality changes after severe brain injury could aid in identification of early and effective interventions that might ease the burden associated with this condition. .

Return-to-Work According to Impairment Type Among Occupationally Injured Workers in Korea

This study examined the association between return-to-work and impairment type. Database of the Korea Workers' Compensation and Welfare Service was used to identify disabled persons; and return-to-work information was obtained from the Korea Employment Information Services database. The study participants were 79,328 persons who received Workers' compensation and who were confirmed as disabled during 2009-2011. Logistic regression was used to analyze the association between return-to-work and impairment type, adjusted by age, sex, impairment severity, pre-injury businesses size, and pre-injury occupational category. Compared to injuries of the upper limbs, the odds ratio of return-to-work was 0.63 (95% CI, 0.60-0.65) for injuries involving the lower limbs, 0.62 (95% CI, 0.59-0.66) for the spine, 0.75 (95% CI, 0.66-0.86) for the eyes, 0.98 (95% CI, 0.77-1.25) for the oral cavity, 0.44 (95% CI, 0.37-0.53) for the ears, 1.02 (95% CI, 0.83-1.25) for the figure, 0.75 (95% CI, 0.72-0.79) for pain, and 0.36 (95% CI, 0.32-0.41) for neuropsychiatric impairment. These findings indicate that impairment type influences return-to-work rates.
