Risk factors and outcome of acute kidney injury in elderly trauma patients.

BACKGROUND: Acute Kidney Injury (AKI) is associated with significant morbidity. The risk factors for AKI in elderly trauma patients have not been defined. METHODS: Injured patients 75 years old or older from 2014 to 2016 were evaluated. AKI was identified by RIFLE criteria. Patients with and without AKI were compared with chi square, ANOVA, and logistic regression. RESULTS: 836 patients were 75 years old or older. Patients with AKI were more commonly male, hypotensive on admission with a greater Injury Severity Score but age, diabetes, hypertension and baseline creatinine were similar. Patients with AKI had a higher mortality that did not increase with RIFLE stage. Male sex, ISS, hypotension on admission and presence of an extremity injury were independently associated with AKI by logistic regression. CONCLUSION: AKI in elderly trauma patients is associated with magnitude of injury and shock but not pre-existing medical comorbidities and it significantly increased the risk of death.

Postsplenectomy vaccination guideline adherence: Opportunities for improvement.

BACKGROUND AND PURPOSE: Patients undergoing splenectomy for trauma are at life-long risk for rapidly progressive septicemia. The purpose of this study was to investigate long-term patient understanding and follow-up with recommendations regarding their asplenia. METHODS: Patients undergoing splenectomy for trauma January 2010-December 2014 were analyzed. Medical records were reviewed and telephone follow-up interviews were conducted in October-December 2015. Patients were asked a standard set of questions that included hospitalizations, awareness of infectious risks associated with asplenia, need for revaccination, and vaccines they had received since their index hospitalization. FINDINGS: Two hundred forty-four patients underwent splenectomy during the study period. A total of 95 patients (39%) were included in the study. Thirty (32%) had been hospitalized since their trauma admission. Only 46% were aware of the risks for sepsis and the need to revaccinate. Only 7% reported having rapid access to antibiotics. CONCLUSIONS: Despite uniform education prior to discharge, most patients undergoing splenectomy for trauma were unaware of the risks for sepsis and did not follow recommended guidelines for risk reduction. IMPLICATIONS FOR PRACTICE: Improvements that have direct implications for advanced practice included the need to refer for vaccination, educate regarding infection risks, and facilitate rapid access to antibiotic treatment.

Danger on the Farm: A Comparison of Agricultural and Animal-Related Injuries.

Animal-related injuries are common in rural areas. Agricultural workers can suffer severe injuries involving farm machinery or falls. The spectrum of injuries related to rural activities is poorly defined and characterizing these injuries will improve injury prevention efforts. Records for injured patients admitted between 2010 and 2013 were retrospectively reviewed. Patients with a mechanism of injury involving a large animal or with the injury site listed as "farm" were included. Patients with agricultural injuries (n = 85) were older with more multisystem injuries than patients injured by animals (n = 132) but the Injury Severity Score was equivalent. There was no difference in intensive care unit length of stay, ventilator days, or mortality. There was no difference in frequency of solid organ injury, pelvic fractures, rib fractures, or hemo- or pneumothorax between groups. Animal injuries had more frequent traumatic brain injuries (22.4% vs 10.5%, P = 0.03), whereas agricultural injuries had more vertebral fractures (20.5% vs 9.2%). Of toxicology screens performed, 25 per cent (22/88) were positive. No significant differences were found between occupational versus recreational animal injuries. Agricultural and animal-related injuries have different characteristics but Injury Severity Score and mortality were similar. Severe injuries from both mechanisms are common in rural communities and injury prevention activities are needed in both settings.

Traumatic injury may be a predisposing factor for cerebrovascular accident.

The purpose of the study was to assess whether trauma may be an independent risk factor for stroke. Evidence has shown that trauma patients experience a hypercoagulable state postinjury, increasing the risk of thrombotic events. A case-controlled, retrospective analysis was performed on admitted trauma patients over a 2-year period. Results revealed that trauma patients are 1.6 times more likely to have a cerebrovascular accident (CVA) during their hospital admission, when compared with nontrauma patients with similar CVA risk factors. Several statistically significant differences between the groups were identified. On the basis of these results, trauma appears to be an independent, nonmodifiable risk factor for CVA.
