Risks factors for significant injury after geriatric falls.

Elderly falls are a healthcare epidemic. We aimed to identify risk factors of serious falls by linking data on functional status from the Global Longitudinal Study of Osteoporosis in Women (GLOW) and our institutional trauma registry. 124 of 5,091 local women enrolled in GLOW were evaluated by our trauma team for injuries related to a fall during the study period. Median injury severity score was 9. The most common injuries were intertrochanteric femur fracture (n = 25, 9.8%) and skin contusion/hematoma to face (n = 12, 4.7%). Injured women were older than the uninjured cohort (median 80 versus 68 years), more likely to have cardiovascular disease and osteoarthritis, and less likely to have high cholesterol. Prospectively collected Short Form 36 (SF-36) baseline activity status revealed greater limitation in all assessed activities in women evaluated for fall-related injuries in our trauma center. In multivariable analysis, age (per 10 year increase) and two or more self-reported falls in the baseline survey were the strongest predictors of falling (both HR 2.4, p <0.0001 and p<0.001 respectively), followed by history of osteoarthritis (HR 1.6, p= 0.01). Functional status was no longer associated with risk of fall when adjusting for these factors. Functional status appears to be a surrogate marker for frailty. With the aging of the US population and long lifespan of American women, this finding has important implications for both fall prevention strategies and research intended to better understand why aging women fall as burdensome validated metrics may not be the best indicators of fall risk.

Improving patient notification of solid abdominal viscera incidental findings with a standardized protocol.

BACKGROUND: The increasing use of computed tomography (CT) scans in the evaluation of trauma patients has led to increased detection of incidental radiologic findings. Incidental findings (IFs) of the abdominal viscera are among the most commonly discovered lesions and can carry a risk of malignancy. Despite this, patient notification regarding these findings is often inadequate. METHODS: We identified patients who underwent abdominopelvic CTs as part of their trauma evaluation during a recent 1-year period (9/2011-8/2012). Patients with IFs of the kidneys, liver, adrenal glands, pancreas and/or ovaries had their charts reviewed for documentation of the lesion in their discharge paperwork or follow-up. A quality improvement project was initiated where patients with abdominal IFs were verbally informed of the finding, it was noted on their discharge summary and/or were referred to specialists for evaluation. Nine months after the implementation of the IF protocol, a second chart review was performed to determine if the rate of patient notification improved. RESULTS: Of 1,117 trauma patients undergoing abdominopelvic CT scans during the 21 month study period, 239 patients (21.4%) had 292 incidental abdominal findings. Renal lesions were the most common (146 patients, 13% of all patients) followed by hepatic (95/8.4%) and adrenal (38/3.4%) lesions. Pancreatic (10/0.9%) and ovarian lesions (3/0.3%) were uncommon. Post-IF protocol implementation patient notification regarding IFs improved by over 80% (32.4% vs. 17.7% pre-protocol, p = 0.02). CONCLUSION: IFs of the solid abdominal organs are common in trauma patients undergoing abdominopelvic CT scan. Patient notification regarding these lesions is often inadequate. A systematic approach to the documentation and evaluation of incidental radiologic findings can significantly improve the rate of patient notification.

Quadrimodal distribution of death after trauma suggests that critical injury is a potentially terminal disease.

BACKGROUND: Patterns of death after trauma are changing due to advances in critical care. We examined mortality in critically injured patients who survived index hospitalization. METHODS: Retrospective analysis of adults admitted to a Level-1 trauma center (1/1/2000-12/31/2010) with critical injury was conducted comparing patient characteristics, injury, and resource utilization between those who died during follow-up and survivors. RESULTS: Of 1,695 critically injured patients, 1,135 (67.0%) were discharged alive. As of 5/1/2012, 977/1,135 (86.0%) remained alive; 75/158 (47.5%) patients who died during follow-up, died in the first year. Patients who died had longer hospital stays (24 vs. 17 days) and ICU LOS (17 vs. 8 days), were more likely to undergo tracheostomies (36% vs. 16%) and gastrostomies (39% vs. 16%) and to be discharged to rehabilitation (76% vs. 63%) or skilled nursing (13% vs. 5.8%) facilities than survivors. In multivariable models, male sex, older age, and longer ICU LOS predicted mortality. Patients with ICU LOS >16 days had 1.66 odds of 1-year mortality vs. those with shorter ICU stays. CONCLUSIONS: ICU LOS during index hospitalization is associated with post-discharge mortality. Patients with prolonged ICU stays after surviving critical injury may benefit from detailed discussions about goals of care after discharge.

Not just full of hot air: hyperbaric oxygen therapy increases survival in cases of necrotizing soft tissue infections.

BACKGROUND: The utility of hyperbaric oxygen therapy (HBOT) in the treatment of necrotizing soft tissue infections (NSTIs) has not been proved. Previous studies have been subject to substantial selection bias because HBOT is not available universally at all medical centers, and there is often considerable delay associated with its initiation. We examined the utility of HBOT for the treatment of NSTI in the modern era by isolating centers that have their own HBOT facilities. METHODS: We queried all centers in the University Health Consortium (UHC) database from 2008 to 2010 that have their own HBOT facilities (n=14). Cases of NSTI were identified by International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes, which included Fournier gangrene (608.83), necrotizing fasciitis (728.86), and gas gangrene (040.0). Status of HBOT was identified by the presence (HBOT) or absence (control) of ICD-9 procedure code 93.95. Our cohort was risk-stratified and matched by UHC's validated severity of illness (SOI) score. Comparisons were then made using univariate tests of association and multivariable logistic regression. RESULTS: There were 1,583 NSTI cases at the 14 HBOT-capable centers. 117 (7%) cases were treated with HBOT. Univariate analysis showed that there was no difference between HBOT and control groups in hospital length of stay, direct cost, complications, and mortality across the three less severe SOI classes (minor, moderate, and major). However, for extreme SOI the HBOT group had fewer complications (45% vs. 66%; p<0.01) and fewer deaths (4% vs. 23%; p<0.01). Multivariable analysis showed that patients who did not receive HBOT were less likely to survive their index hospitalization (odds ratio, 10.6; 95% CI 5.2-25.1). CONCLUSION: At HBOT-capable centers, receiving HBOT was associated with a significant survival benefit. Use of HBOT in conjunction with current practices for the treatment of NSTI can be both a cost-effective and life-saving therapy, in particular for the sickest patients.

Epidemiology and outcomes of community-acquired Clostridium difficile infections in Medicare beneficiaries.

BACKGROUND: The incidence of community-acquired Clostridium difficile (CACD) is increasing in the United States. Many CACD infections occur in the elderly, who are predisposed to poor outcomes. We aimed to describe the epidemiology and outcomes of CACD in a nationally representative sample of Medicare beneficiaries. STUDY DESIGN: We queried a 5% random sample of Medicare beneficiaries (2009-2011 Part A inpatient and Part D prescription drug claims; n = 864,604) for any hospital admission with a primary ICD-9 diagnosis code for C difficile (008.45). We examined patient sociodemographic and clinical characteristics, preadmission exposure to oral antibiotics, earlier treatment with oral vancomycin or metronidazole, inpatient outcomes (eg, colectomy, ICU stay, length of stay, mortality), and subsequent admissions for C difficile. RESULTS: A total of 1,566 (0.18%) patients were admitted with CACD. Of these, 889 (56.8%) received oral antibiotics within 90 days of admission. Few were being treated with oral metronidazole (n = 123 [7.8%]) or vancomycin (n = 13 [0.8%]) at the time of admission. Although 223 (14%) patients required ICU admission, few (n = 15 [1%]) underwent colectomy. Hospital mortality was 9%. Median length of stay among survivors was 5 days (interquartile range 3 to 8 days). One fifth of survivors were readmitted with C difficile, with a median follow-up time of 393 days (interquartile range 129 to 769 days). CONCLUSIONS: Nearly half of the Medicare beneficiaries admitted with CACD have no recent antibiotic exposure. High mortality and readmission rates suggest that the burden of C difficile on patients and the health care system will increase as the US population ages. Additional efforts at primary prevention and eradication might be warranted.

The dangers of being a "weekend warrior": a new call for injury prevention efforts.

BACKGROUND: Nonprofessionals routinely perform high-risk home maintenance activities otherwise regulated by the Occupational Health and Safety Administration when professionals perform the same work. Reducing the risks taken by these "weekend warriors" has not been the focus of injury prevention efforts. This study describes injury patterns and outcomes for nonprofessionals attempting home roof and tree maintenance. METHODS: We queried our trauma registry for all adult patients (age, ≥18 years) with injury codes for "fall-from-height" or "struck-by-tree" (2005-present) and reviewed charts to determine injuries sustained during home roof or tree work. Patients injured during occupational duties (indicated by Workman's Compensation) were excluded. Descriptive statistics were used to determine patient demographics, injury patterns, and outcomes. RESULTS: A total of 129 patients were injured performing roof and tree maintenance during the study period. Of these patients, 90 (69.8%) were fall from height and 39 (30.2%) were struck by tree. Mean (SD) age was 45 (14) years. The majority were male (124, 96.1%) and white (116, 89.9%). Nearly half (59, 45.7%) were privately insured; a quarter (32, 24.8%) had no insurance. Mean (SD) Injury Severity Score was 12.7 (9.3). Injury distributions were as follows: head injury, 48.8%; facial fractures, 10.1%; cervical spine fractures, 3.9%; thoracic, lumbar, and sacral spine fractures, 28.1%; rib fractures, 27.3%; intrathoracic injuries, 22.5%; liver/spleen injuries, 6.2%; pelvic fractures, 15.6%; upper-extremity fractures, 27.3%; and lower-extremity fractures, 14.7%. Of the patients, 19 (14.7%) had one or more regions with Abbreviated Injury Scale score of higher than 3. Mean (SD) length of stay was 5.3 (7.6) days. Except for 2 deaths (1.6%), discharge dispositions were as follows: home, 64.2%; home with services, 10.1%; rehabilitation, 17.8%; and skilled nursing, 5.4%. CONCLUSION: Weekend warriors performing home roof and tree maintenance sustain serious injuries with a potential for a long-term disability at young ages. Injury prevention efforts should educate the public about the hazards of high-risk home maintenance, possibly encouraging Occupational Health and Safety Administration-regulated protective measures or deferral to trained professionals.

Management of the most severely injured spleen: a multicenter study of the Research Consortium of New England Centers for Trauma (ReCONECT).

OBJECTIVE: To determine the rate and predictors of failure of nonoperative management (NOM) in grade IV and V blunt splenic injuries (BSI). DESIGN: Retrospective case series. SETTING: Fourteen trauma centers in New England. PATIENTS: A total of 388 adult patients with a grade IV or V BSI who were admitted between January 1, 2001, and August 31, 2008. MAIN OUTCOME MEASURES: Failure of NOM (f-NOM). RESULTS: A total of 164 patients (42%) were operated on immediately. Of the remaining 224 who were offered a trial of NOM, the treatment failed in 85 patients (38%). At the end, 64% of patients required surgery. Multivariate analysis identified 2 independent predictors of f-NOM: grade V BSI and the presence of a brain injury. The likelihood of f-NOM was 32% if no predictor was present, 56% if 1 was present, and 100% if both were present. The mortality of patients for whom NOM failed was almost 7-fold higher than those with successful NOM (4.7% vs 0.7%; P = .07). CONCLUSIONS: Nearly two-thirds of patients with grade IV or V BSI require surgery. A grade V BSI and brain injury predict failure of NOM. This data must be taken into account when generalizations are made about the overall high success rates of NOM, which do not represent severe BSI.
