Post-hospitalization Treatment Regimen and Readmission for C. difficile Colitis in Medicare Beneficiaries.

BACKGROUND: C. difficile (CDI) has surpassed methicillin-resistant staph aureus as the most common nosocomial infection with recurrence reaching 30% and the elderly being disproportionately affected. We hypothesized that post-discharge antibiotic therapy for continued CDI treatment reduces readmissions. STUDY DESIGN: We queried a 5% random sample of Medicare claims (2009-2011 Part A and Part D; n = 864,604) for hospitalizations with primary or secondary diagnosis of CDI. We compared demographics, comorbidities, and post-discharge CDI treatment (no CDI treatment, oral metronidazole only, oral vancomycin only, or both) between patients readmitted with a primary diagnosis of CDI within 90 days and patients not readmitted for any reason using univariate tests of association and multivariable models. RESULTS: Of 7042 patients discharged alive, 945 were readmitted ≤90 days with CDI (13%), while 1953 were not readmitted for any reason (28%). Patients discharged on dual therapy had the highest rates of readmission (50%), followed by no post-discharge CDI treatment (43%), vancomycin only (28%), and metronidazole only (19%). Patients discharged on only metronidazole (OR 0.28) or only vancomycin (OR 0.42) had reduced odds of 90-day readmission compared to patients discharged on no CDI treatment. Patients discharged on dual therapy did not vary in odds of readmission. CONCLUSIONS: Thirteen percent of patients discharged with CDI are readmitted within 90 days. Patients discharged with single-drug therapy for CDI had lower readmission rates compared to patients discharged on no ongoing CDI treatment suggesting that short-term monotherapy may be beneficial in inducing eradication and preventing relapse. Half of patients requiring dual therapy required readmission, suggesting patients with symptoms severe enough to warrant discharge on dual therapy may benefit from longer hospitalization.

It's All About Location, Location, Location: A New Perspective on Trauma Transport.

OBJECTIVE: To determine the effect of aeromedical transport on trauma mortality when accounting for geographic factors. BACKGROUND: The existing literature on the mortality benefit of aeromedical transport on trauma mortality is controversial. Studies examining patient and injury characteristics find higher mortality, whereas studies measuring injury severity find a protective effect. Previous studies have not adjusted for the time and distance that would have been traveled had a helicopter not been used. METHODS: Retrospective analysis of an institutional trauma registry. We compared mortality among adult patients (≥15 years) transported from the scene of injury to our level I trauma center by air or ground (January 1, 2000-December 31, 2010) using univariate comparisons and multivariable logistic regression. Regression models were constructed to incrementally account for patient demographics and injury mechanism, followed by injury severity, and, finally, by network bands for drive time and roadway distance as predicted by geographic information systems. RESULTS: Of 4522 eligible patients, 1583 (35%) were transported by air. Patients transported by air had higher unadjusted mortality (4.1% vs 1.9%, P < 0.05). In multivariable modeling, including patient demographics and type of injury, helicopter transport predicted higher mortality than ground transport (odds ratio [OR] 2.4, 95% confidence interval [CI] 1.2-4.0). After adding validated injury severity measures to the model, helicopter transport predicted lower mortality (OR 0.7, 95% CI 0.3-0.9). Finally, including geographic covariates found that helicopter transport was not associated with mortality (OR 1.1, 95% CI 0.6-2.3). CONCLUSIONS: Helicopter transport does not impart a survival benefit for trauma patients when geographic considerations are taken into account.

Contemporary trends in necrotizing soft-tissue infections in the United States.

BACKGROUND: Necrotizing soft-tissue infections (NSTI) are rare, potentially fatal, operative emergencies. We studied a national cohort of patients to determine recent trends in incidence, treatment, and outcomes for NSTI. METHODS: We queried the Nationwide Inpatient Sample (1998-2010) for patients with a primary diagnosis of NSTI. Temporal trends in patient characteristics, treatment (debridement, amputation, hyperbaric oxygen therapy [HBOT]), and outcomes were determined with Cochran-Armitage trend tests and linear regression. To account for trends in case mix (age, sex, race, insurance, Elixhauser index) or receipt of HBOT on outcomes, multivariable analyses were conducted to determine the independent effect of year of treatment on mortality, any major complication, and hospital length of stay (LOS) for NSTI. RESULTS: We identified 56,527 weighted NSTI admissions, with an incidence ranging from approximately 3,800-5,800 cases annually. The number of cases peaked in 2004 and then decreased between 1998 and 2010 (P < .0001). The percentage of female patients decreased slightly over time (38.6-34.1%, P < .0001). Patients were increasingly in the 18- to 34-year-old (8.8-14.6%, P < .0001) and 50- to 64-year-old age groups (33.2-43.5, P < .0001), Hispanic (6.8-10.5%, P < .0001), obese (8.9-24.6%, P < .0001), and admitted with >3 comorbidities (14.5-39.7%, P < .0001). The percentage of patients requiring only one operative debridement increased somewhat (43.2-46.2%, P < .0001), whereas the use of HBOT was rare and decreasing (1.6-0.8%, P < .0001). The percentage of patients requiring operative wound closure decreased somewhat (23.5-20.8%, P < .0001). Although major complication rates increased (30.9-48.2%, P < .0001), hospital LOS remained stable (18-19 days) and mortality decreased (9.0-4.9%, P < .0001) on univariate analyses. On multivariable analyses each 1-year incremental increase in year was associated with a 5% increased odds of complication (odds ratio 1.05), 0.4 times decrease in hospital LOS (coefficient -0.41), and 11% decreased odds of mortality (odds ratio 0.89). CONCLUSION: There were potentially important national trends in patient characteristics and treatment patterns for NSTI between 1998 and 2010. Importantly, though patient acuity worsened and complication rates increased, but LOS remained relatively stable and mortality decreased. Improvements in early diagnosis, wound care, and critical care delivery may be the cause.

A Mycobacterium bovis mycotic abdominal aortic aneurysm resulting from bladder cancer treatment, resection, and reconstruction with a cryopreserved aortic graft.

Mycotic abdominal aortic aneurysms (AAAs) are a clinical challenge for vascular surgeons due to their critical location, surrounding inflammation, risk of rupture, and danger of reinfection following treatment. We present a case of Mycobacterium bovis AAA in a 69-year-old male after treatment with intravesicular bacillus Calmette-Guérin (BCG) therapy for bladder carcinoma. The classical approach for mycotic AAA entails extra-anatomic reconstruction followed by resection with oversewing of the proximal and distal aortic stumps. Alternative in-line reconstruction options have also been advocated. This case illustrates a technically straightforward, durable, in-line repair within an infected field utilizing cryopreserved aortic allograft.

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.

Multicystic peritoneal mesothelioma in an octogenarian: diagnosis, natural history, and treatment.

Multicystic peritoneal mesothelioma (MCPM) is a rare cystic proliferation most often seen in women of reproductive age with a history of prior abdominal surgery. This is a case report of an 83-year-old woman diagnosed with MCPM during an exploratory laparotomy for presumed peritoneal carcinomatosis from colon cancer. After complete removal of all visible MCPM, the patient remains free of both colon cancer and MCPM. This article reviews the literature with regards to the pathology, natural history, risk of malignant transformation, and current options for management of MCPM, including cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Use of gauze-based negative pressure wound therapy in a pediatric burn patient.

Negative pressure wound therapy (NPWT) is described as it is used in the treatment of an infant burn victim. This case highlights the ability and techniques used to maintain an airtight dressing seal in the perirectal region. Use of this dressing type post-skin grafting allowed for 100% graft adhesion and no bacterial contamination despite close proximity to the rectum. Favorable experience and outcome with this patient are strong indicators that NPWT should be considered as a viable treatment in pediatric populations and that situations where body contour or fluids may make NPWT difficult to administer should not be a deterrent to therapy.
