Acute Posttraumatic Renal Failure: A Multicenter Perspective.

UNLABELLED: Acute renal failure (ARF) following trauma is rare. Historically, ARF has been associated with a high mortality rate. To investigate this entity we conducted a retrospective review of 72,757 admissions treated at nine regional trauma centers over a 5-year period. Seventy-eight patients (0.098%) developed acute renal failure requiring hemodialysis. Detailed demographic, clinical, and outcome data were collected. Patients with pre-existing medical conditions (group I) had a 70% increase in mortality over those without pre-existing conditions (p less than 0.004). Twenty-four patients (31%) developed ARF less than 6 days after injury (group II). The remainder (group III) developed late renal failure (mean time to first dialysis, 23 days). The predominant cause of death was multiple organ failure (82%). There were no differences in mortality because of multiple organ failure among the three groups of patients. Of the 33 survivors, six (18%) were discharged with renal insufficiency, three (9%) were discharged on dialysis, 23 (70%) were discharged home or to rehabilitation, and 27 (82%) had no significant evidence of renal insufficiency. CONCLUSION: Posttraumatic renal failure requiring hemodialysis is rare (incidence, 107 per 100,000 trauma center admissions), but the mortality rate remains high (57%). Two thirds of the cases of posttraumatic renal failure develop late and are secondary to multiple organ failure; one third of the cases of posttraumatic renal failure develop early and may result from inadequate resuscitation

Centers for Medicare and Medicaid services quality indicators do not correlate with risk-adjusted mortality at trauma centers.

OBJECTIVES: The Centers for Medicare and Medicaid Services (CMS) publicly reports hospital compliance with evidence-based processes of care as quality indicators. We hypothesized that compliance with CMS quality indicators would correlate with risk-adjusted mortality rates in trauma patients. METHODS: A previously validated risk-adjustment algorithm was used to measure observed-to-expected mortality ratios (O/E with 95% confidence interval) for Level I and II trauma centers using the National Trauma Data Bank data. Adult patients (\u3eor=16 years) with at least one severe injury (Abbreviated Injury Score \u3eor=3) were included (127,819 patients). Compliance with CMS quality indicators in four domains was obtained from Hospital Compare website: acute myocardial infarction (8 processes), congestive heart failure (4 processes), pneumonia (7 processes), surgical infections (3 processes). For each domain, a single composite score was calculated for each hospital. The relationship between O/E ratios and CMS quality indicators was explored using nonparametric tests. RESULTS: There was no relationship between compliance with CMS quality indicators and risk-adjusted outcomes of trauma patients. CONCLUSIONS: CMS quality indicators do not correlate with risk-adjusted mortality rates in trauma patients. Hence, there is a need to develop new trauma-specific process of care quality indicators to evaluate and improve quality of care in trauma centers
