Evidence-based guidelines for the care of severe traumatic brain injury have been available from the Brain Trauma Foundation (BTF) since 1995. A total of 15 recommendations compose the current guidelines. Although each individual guideline has been validated in isolation, to date, little research has examined the guidelines in composite. We examined the relationship between compliance with the BTF severe TBI guidelines and mortality. ⋯ Our data indicate that full compliance with all 15 severe TBI guidelines is difficult to achieve and may not be necessary to optimally care for patients.

In haemodynamic stable patients without an acute abdomen, nonoperative management (NOM) of blunt liver injuries (BLI) has become the standard of care with a reported success rate of between 80 and 100%. Concern has been expressed about the potential overuse of NOM and the fact that failed NOM is associated with higher mortality rate. The aim of this study was to evaluate factors that might indicate the need for surgical intervention, and to assess the efficacy of NOM. ⋯ Physiologic behaviour or CT findings dictated the need for operative intervention. NOM of BLI has a high success rate (95%). Nonoperative management of BLI should be considered in patients who respond to resuscitation, irrespective of the grade of liver trauma. Associated intraabdominal solid organ injuries do not exclude NOM.

To evaluate potential reduction in health-related quality of life (HRQOL) after a mild to moderate trauma. ⋯ After a mild trauma, we evidenced a relevant reduction in HRQOL; an advanced age and a higher degree of organ dysfunction were independently associated with HRQOL deterioration.

This large retrospective observational cohort study evaluated prognostic factors, 30-day morbidity and mortality and complications related to the pancreas in patients who had sustained pancreatic injuries. ⋯ Morbidity was 64% and AAST grade of pancreatic injury and a repeat laparotomy were significant predictors of morbidity. Overall mortality was 15.7%. Most deaths were due to associated injuries and were unrelated to the pancreatic injury. Five variables, age, shock, median number of units transfused and the presence of associated complications were significant factors associated with mortality. These data indicate that the magnitude of blood loss and haemorrhagic shock are primary determinants for survival and that urgent reversal of shock and control of bleeding are essential to reduce mortality in this cohort of patients.

Collider bias, or stratifying data by a covariate consequence rather than cause (confounder) of treatment and outcome, plagues randomised and observational trauma research. Of the seven trials of prehospital hypertonic saline in dextran (HSD) that have been evaluated in systematic reviews, none found an overall between-group difference in survival, but four reported significant subgroup effects. We hypothesised that an avoidable type of collider bias often introduced inadvertently into trauma comparative effectiveness research could explain the incongruous findings. ⋯ HSD delayed blood transfusion by modifying standard triggers like SBP with no detectable effect on survival. The reported heterogeneous HSD effects in subgroups can be explained by collider bias that trauma researchers can avoid by improved covariate selection and data capture strategies.
