Not Just Full of Hot Air: Hyperbaric Oxygen Therapy Increases Survival in Cases of Necrotizing Soft Tissue Infections

INTRODUCTION: The utility of hyperbaric oxygen therapy (HBOT) in the treatment for necrotizing soft tissue infections (NSTI) has not been proven. Previous studies have been subject to significant selection bias since HBOT is not universally available 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 ICD-9 diagnosis codes, which included Fournier’s gangrene (608.83), necrotizing fascitis (728.86), and gas gangrene (040.0). HBOT treatment status was identified by the presence (HBOT) or absence (CONTROL) of ICD-9 procedure code (93.95). We then risk stratified and matched our cohort 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. Risk stratified univariate outcomes are summarized in the table. There was no difference between HBOT and CONTROL groups in hospital length of stay (LOS), 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 CONCLUSION: At HBOT capable centers, receiving HBOT was associated with a significant survival benefit. HBOT in conjunction with current practices for the treatment of NSTI can be both a cost effective and life saving therapy

The Effect of Oral Antibiotics on the Development of Community Acquired Clostridium Difficile Colitis in Medicare Beneficiaries

Clostridium difficile infection (CDI) is increasingly prevalent among community dwelling Americans. Older Americans are particularly vulnerable to community-acquired Clostridium difficile (CACD), in part to increasing use of antibiotics. We studied the association between outpatient antibiotics and CACD among Medicare beneficiaries. Case-control study utilizing a 5% sample of Medicare beneficiaries (2009-2011). Patients with CACD severe enough to warrant hospitalization were identified by a primary diagnosis code for CDI and no exposure to a healthcare environment within 90-days of admission. 1,514 CACD cases were matched to ten controls each on birth year and sex. Potential controls with exposure to healthcare environment were excluded. Outpatient oral antibiotic exposure was classified into three groups: ≤30 days, 31-60 days, or 61-90 days prior to case subject’s index admission. Metronidazole and Vancomycin were excluded because they are used to treat CDI. Multivariable models were utilized to determine the independent effect of antibiotics on the development of CACD while controlling for several patient associated characteristics. Cases of CACD had more outpatient antibiotic exposure in each time period examined: ≤30 days = 40.0% vs 8.4%; 31-60 = 10.7% vs 5.0%; and 61-90 = 5.5% vs 4.4% (all p-values \u3c 0.05). Subjects exposed to antibiotics ≤30 days prior to admission had a markedly higher risk of being admitted with CACD compared with those not exposed (OR 8.09, 95% CI 7.13, 9.19). Similarly, subjects taking antibiotics 31-60 days and 61-90 days prior to admission had increased risk of CDI admission (OR 3.65, 95% CI 3.02, 4.41) and (OR 2.06, 95% CI 1.61, 2.63) respectively. Recent exposure to outpatient oral antibiotics increases the risk of CACD among community dwelling elderly with the risk persisting as long as 90 days after exposure. Inappropriate antibiotic usage must be minimized and older Americans who require outpatient antibiotic treatment may warrant close observation for signs of CDI

A qualitative analysis of migrant social workers’ work experiences and perceived prejudice from an empowering acculturative integration approach

An increasing number of migrant social workers are employed in the UK social work sector. This article explores the acculturative integration experiences of a small group of migrant social workers. We critically observe that research on migrant professionals’ trajectories should adopt theories that emphasise people’s empowerment and potential for agency. We use a framework drawing on liberation psychology for analysing the autobiographical narratives of a sample of migrant social workers employed in England. Findings indicate that the participants perceived prejudice on a number of occasions and circumstances. Even though in their narrative of survival they talked about activating several psychosocial resources, they were sceptical about their professional development and dissatisfied at work. The paper discusses the emerging findings while highlighting the framework’s relevance for understanding these experiences from an empowering acculturation perspective and suggesting ways of improving migrant social workers’ acculturative integration by addressing systemic barriers

Quadrimodal Distribution of Death after Trauma: Predictors of Death in the Fourth Peak

Introduction: Patterns of death after trauma are changing due to diagnostic and treatment advances. We examined mortality in critically injured patients at risk of death after discharge. Methods: We reviewed all critically injured (Injury Severity Score≥25 AND death in Emergency Room , death within 24hrs, OR ICU admission\u3e24hrs) adults (age≥18) admitted to a Level 1 trauma center (01/01/2000-12/31/2010) and determined death post-discharge (Social Security Death Index) of patients discharged alive. We compared demographics, injury data, and critical care resource utilization between those who died during follow-up and survivors using univariate tests and Cox proportional hazards models. Results: Of 1,695 critically injured patients, 1135 (67%) were discharged alive. As of 05/1/2012, 977 (58%) index survivors were alive (median follow-up 62mos (IQR35,96)). Of 158 deaths post-discharge, 75 (47%) occurred within the first year. Patients who died post-discharge had longer hospital (24dys (IQR13,38) vs. 17dys (IQR10,27)) and ICU LOS (17dys (IQR6,29) vs. 8dys (IQR4,19)) and were more likely to undergo tracheostomies (36.1% vs. 15.6%, p16dys increased risk of death at one year (HR1.94 (1.22,3.06)) and by the end of follow-up (HR2.19 (1.58,3.04)) compared to shorter ICU stays. Conclusion: We propose the first year after discharge as the fourth peak of trauma related mortality. Duration of ICU LOS during index hospitalization is associated with post-discharge mortality

Efficacy and safety of ripretinib in patients with KIT-altered metastatic melanoma.

BACKGROUND: Ripretinib, a broad-spectrum KIT and platelet-derived growth factor receptor A switch-control tyrosine kinase inhibitor, is approved for the treatment of adult patients with advanced gastrointestinal stromal tumor as ≥ fourth-line therapy. We present the efficacy and safety of ripretinib in patients with KIT-altered metastatic melanoma enrolled in the expansion phase of the ripretinib phase I study. PATIENTS AND METHODS: Patients with KIT-altered metastatic melanoma were enrolled and treated with ripretinib at the recommended phase II dose of 150 mg once daily in 28-day cycles. Investigator-assessed responses according to Response Evaluation Criteria In Solid Tumors version 1.1 were carried out on day 1 of cycles 3, 5, 7, every three cycles thereafter, and at a final study visit. RESULTS: A total of 26 patients with KIT-altered metastatic melanoma (25 with KIT mutations, 1 with KIT-amplification) were enrolled. Patients had received prior immunotherapy (n = 23, 88%) and KIT inhibitor therapy (n = 9, 35%). Confirmed objective response rate (ORR) was 23% [95% confidence interval (CI) 9%-44%; one complete and five partial responses] with a median duration of response of 9.1 months (range, 6.9-31.3 months). Median progression-free survival (mPFS) was 7.3 months (95% CI 1.9-13.6 months). Patients without prior KIT inhibitor therapy had a higher ORR and longer mPFS (n = 17, ORR 29%, mPFS 10.2 months) than those who had received prior KIT inhibitor treatment (n = 9, ORR 11%, mPFS 2.9 months). The most common treatment-related treatment-emergent adverse events (TEAEs) of any grade in ≥15% of patients were increased lipase, alopecia, actinic keratosis, myalgia, arthralgia, decreased appetite, fatigue, hyperkeratosis, nausea, and palmar-plantar erythrodysesthesia syndrome. There were no grade ≥4 treatment-related TEAEs. CONCLUSIONS: In this phase I study, ripretinib demonstrated encouraging efficacy and a well-tolerated safety profile in patients with KIT-altered metastatic melanoma, suggesting ripretinib may have a clinically meaningful role in treating these patients

Rates of Insurance for Injured Patients before and after Health Care Reform in Massachusetts: Another Case of Double Jeopardy?

Background: As a result of healthcare reform (HCR), insurance rates among Massachusetts (MA) residents increased from 86.6% (2006) to 94.4% (2010) and conferred a 7.6% higher probability of being insured compared to neighboring states. The effect of an individual mandate on insurance rates among trauma patients is unknown. Methods: This was retrospective analysis of adult (18-64yrs) trauma patients from MA and surrounding states (NH, RI, CT, NY, VT) treated at our level 1 trauma center in central MA before (2004-2005) and after (2009-2010) MA-HCR. We estimated changes in insurance rates across time-periods and state-residence. Results: Before MA-HCR, 76.7% (1647/2,148) of injured MA residents had insurance compared to 84.3% (2088/2477) post-HCR (p Conclusions: In this single center study, time rather than HCR resulted in modest increases in insurance rates. However, MA-HCR was ineffectual at increasing insurance among trauma patients to levels comparable to the general public, suggesting certain factors may place certain subgroups in “double jeopardy” by simultaneously increasing risk of injury and precluding compliance with an individual mandate

Barriers and facilitators to using NHS Direct: a qualitative study of ‘users’ and ‘non-users’

Background NHS Direct, introduced in 1998, has provided 24/7 telephone-based healthcare advice and information to the public in England and Wales. National studies have suggested variation in the uptake of this service amongst the UK¿s diverse population. This study provides the first exploration of the barriers and facilitators that impact upon the uptake of this service from the perspectives of both `users¿ and `non- users¿. Methods Focus groups were held with NHS Direct `users¿ (N?=?2) from Bedfordshire alongside `non-users¿ from Manchester (N?=?3) and Mendip, Somerset (N?=?4). Each focus group had between five to eight participants. A total of eighty one people aged between 21 and 94 years old (M: 58.90, SD: 22.70) took part in this research. Each focus group discussion lasted approximately 90 minutes and was audiotape-recorded with participants¿ permission. The recordings were transcribed verbatim. A framework approach was used to analyse the transcripts. Results The findings from this research uncovered a range of barriers and facilitators that impact upon the uptake of NHS Direct. `Non-users¿ were unaware of the range of services that NHS Direct provided. Furthermore, `non-users¿ highlighted a preference for face-to face communication, identifying a lack of confidence in discussing healthcare over the telephone. This was particularly evident among older people with cognitive difficulties. The cost to telephone a `0845¿ number from a mobile was also viewed to be a barrier to access NHS Direct, expressed more often by `non-users¿ from deprived communities. NHS Direct `users¿ identified that awareness, ease of use and convenience were facilitators which influenced their decision to use the service. Conclusions An understanding of the barriers and facilitators which impact on the access and uptake of telephone-based healthcare is essential to move patients towards the self-care model. This research has highlighted the need for telephone-based healthcare services to increase public awareness; through the delivery of more targeted advertising to promote the service provision availabl

Partnership in practice research: a Norwegian experience

This article outlines some of the issues involved in developing partnerships between service users, practitioners and researchers. It discusses these through some experience in Oslo as part of a national level agreement (HUSK) to improve social services in Norway through research and knowledge development. It begins with a review of the main concepts and debates involved in developing collaborative partnerships for practice-based research, particularly in the social services arena. The HUSK program is then described. The article then traces some specific developments and challenges in negotiating partnership relations as discussed by program participants (users, practitioners and researchers) in a series of workshops designed to elicit the issues directly from their experience
