| Abstrakt: | Objective: To estimate cost-effectiveness ratios and net costs of a training intervention to reduce morbidity among porters who carry loads without mechanical assistance in a developing country informal sector setting. Methods: Pre- and post-intervention survey data (n = 100) were collected in a prospective study: differences in physical/mental composite scores and pain scale scores were computed. Costs and economic benefits of the intervention were monetized with a net-cost model. Results: Significant changes in physical composite scores (2.5), mental composite scores (3.2), and pain scale scores (-1.0) led to cost-effectiveness ratios of $6.97, $5.41, and $17.91, respectively. Multivariate analysis showed that program adherence enhanced effectiveness. The net cost of the intervention was -$5979.00 due to a reduction in absenteeism. Conclusions: Workplace ergonomic training is cost-effective and should be implemented wherein other engineering-control interventions are precluded due to infrastructural constraints. |
