Background & objectives: Trauma is known to lead to systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS), which is often a cause of late deaths after injury. SIRS and MODS have been objectively measured using scoring systems. This prospective observational study was carried out in a tertiary care hospital in India to evaluate SIRS and MODS following trauma in terms of their incidence, the associated risk factors and the effect on the outcome. Methods: All adult patients with major life- and limb-threatening trauma were included. Patients who died within 24 h, those with severe head injury, known comorbidity, immunocompromised state, on immunosuppressants or pregnancy were excluded. SIRS and MODS scores were recorded after initial management (baseline score), on days 3 and 6 of admission. SIRS was defined as SIRS score of ≥2 and MODS was defined as MODS score of ≥1. Results: Two hundred patients were enrolled. SIRS was noted in 156 patients (78%). MODS was noted in 145 (72.5%) patients. Overall mortality was 39 (19.5%). Both SIRS and MODS scores were significantly associated with age >60 yr, blunt injury, (lower) revised trauma score hypotension on admission and (higher) injury severity score, but not with gender, pre-hospital time or operative treatment. Interpretation & conclusions: Both SIRS and MODS scores were associated with longer Intensive Care Unit (ICU) stay, more ICU interventions and higher mortality. Incidence of MODS was significantly higher in patients with SIRS. Both scores showed rising trend with time in non-survivors and a decreasing trend in survivors. The serial assessment of scores can help prognosticate outcome and also allocate appropriate critical care resources to patients with rising scores.
