Evaluación de impacto de las intervenciones de prevención en clientes / Assessment of the impact of prevention interventions in customers

Las prestaciones preventivas son fundamentales para prevenir accidentes laborales. Sin embargo, hasta ahora la Mutual (ACHS) en que se realiza el estudio no contaba con una metodología sistemática para su evaluación. Este trabajo presenta una metodología desarrollada por la organización (mutual) para evaluar las intervenciones preventivas, la cual está basada en Brodersen, K. H., Gallusser, F., Koehler, J., Remy, N., & Scott, S. L.1 Para cada empresa-sucursal se estiman los accidentes que habrían ocurrido de no haberse realizado intervenciones preventivas. Esta serie se compara con la serie real, y se calcula si son diferentes al 95 por ciento de confianza. De ser efectiva, se utiliza en un modelo de regresión lineal que estima el efecto marginal por tipo de intervención. Los supuestos de Brodersen et al.¹ se cumplen en la Mutual, justificando su utilización. Los resultados señalan que la "Capacitación sin propuesta Push", "Plan de acción del modelo preventivo" y "Primeros auxilios psicológicos" tienen efectos significativos en la reducción de accidentes. La "Capacitación con propuesta Push" y "Fuerza de tarea" no muestran efectos significativos. Estos resultados varían según el sector económico. Nuestra recomendación es adoptar esta metodología. También sugerimos implementar metodologías complementarias, para validar su idoneidad.

Preventive services are essential to prevent accidents. However, until now the Mutual did not have a systematic methodology for evaluation. This paper presents a methodology developed by the Mutual to evaluate preventive interventions. It is based on Brodersen, KH, Gallusser, F., Koehler, J., Remy, N., & Scott, SL (2013). For each company-branch, it was estimated accidents that may have occurred if preventive interventions would not have been performed. This series is compared to the actual series, and it is estimated if it is different to 95 percent of confidence. To be effective, it is used in a linear regression model that estimates the marginal effect by type of intervention. Brodersen et al.¹ Assumptions are met in the Mutual, justifying its use. The results indicate that "no proposal Training Push", "preventive action plan model" and "Psychological first aid" have significant effects in reducing accidents. "Training with proposal Push" and "task force" does not show significant effects. These results vary depending on the economic sector. Our recommendation is to adopt this methodology. We also suggest implementing complementary methodologies to validate their suitability.

Is more engaging safety training always better in reducing accidents? Evidence of self-selection from Chilean panel data.

INTRODUCTION: The recent events in Chile involving 33 miners who were trapped and rescued in the San José mine led the government to strongly promote occupational safety and health (OSH) training. However, there is an ongoing debate regarding which type of training is the most effective in reducing accidents. METHOD: The "engagement hypothesis" claims that traditional classrooms are rather ineffective and that only a strong student involvement may generate meaningful results, but the empirical evidence is inconclusive. To contribute to this debate, we claim that the selection of the training method may be contingent on the firm's OSH capabilities and commitment. Firms with fewer (greater) capabilities may optimally self-select less (more) engaging training methods. RESULTS: Accordingly, based on panel data from 2003 to 2009 for a representative sample of 2,787 Chilean firms, the engagement hypothesis initially appears to be supported; however, after correcting for self-selection bias, it loses most of its significance. IMPACT ON INDUSTRY: Chilean policymakers are strongly advised to expand OSH training.
