The goal of this study was to identify predictive factors that influence return to work in burn patients treated at the National Center for Burn Care and Research at the National Institute of Rehabilitation (CENIAQ) in Mexico City. This is a retrospective case-control study that included all burn patients of working age (16-91 years old), treated between January 2011 and December 2013. Patients were divided into two groups: unemployed (no work group) and those who returned to work (RTW). The statistical analysis was performed by a logistic regression univariate and multivariate analysis. A total of 210 subjects were included in the study. The mean age was 38 +/- 15 years and 66.7 of them were male. One hundred sixty-five patients (79.6) were able to return to work after treatment. Through univariate analysis it was found that the predictive factors for not returning to work after injury were: education lower than elementary school (OR: 3.59; CI 95: 1.79-7.32); history of epilepsy prior to burn injury (OR: 10.18; CI 95: 1.9-54.43); total burned surface area (TBSA) >= 20 (OR: 2.87; CI 95: 1.46-5.64); third-degree burns (OR: 2.64; CI 95: 1.32-5.29); hospital stay >= 20 days (OR: 2.8; CI 95: 1.47-5.68); length of stay in the burn intensive care unit (OR: 2.5; CI 95: 1.25-4.97); secondary infection (OR: 2.24; CI 95: 1.15-4.38); amputations (one or more regardless of amputation level; OR: 8; CI 95: 2.52-25.30); burn of the upper extremity (shoulder; OR: 2.21; CI 95: 0.97-5.03); thigh (OR: 2.41; CI 95: 1.32-5.14); and knee (OR: 2.81; CI 95: 1.21-6.55). Some of these factors have never been reported by other authors.
