Surgical and procedural antibiotic prophylaxis in the surgical ICU: an American Association for the Surgery of Trauma Critical Care Committee clinical consensus document.

The use of prophylactic measures, including perioperative antibiotics, for the prevention of surgical site infections is a standard of care across surgical specialties. Unfortunately, the routine guidelines used for routine procedures do not always account for many of the factors encountered with urgent/emergent operations and critically ill or high-risk patients. This clinical consensus document created by the American Association for the Surgery of Trauma Critical Care Committee is one of a three-part series and reviews surgical and procedural antibiotic prophylaxis in the surgical intensive care unit. The purpose of this clinical consensus document is to provide practical recommendations, based on expert opinion, to assist intensive care providers with decision-making for surgical prophylaxis. We specifically evaluate the current state of periprocedural antibiotic management of external ventricular drains, orthopedic operations (closed and open fractures, silver dressings, local, antimicrobial adjuncts, spine surgery, subfascial drains), abdominal operations (bowel injury and open abdomen), and bedside procedures (thoracostomy tube, gastrostomy tube, tracheostomy).

Fever and infections in surgical intensive care: an American Association for the Surgery of Trauma Critical Care Committee clinical consensus document.

The evaluation and workup of fever and the use of antibiotics to treat infections is part of daily practice in the surgical intensive care unit (ICU). Fever can be infectious or non-infectious; it is important to distinguish between the two entities wherever possible. The evidence is growing for shortening the duration of antibiotic treatment of common infections. The purpose of this clinical consensus document, created by the American Association for the Surgery of Trauma Critical Care Committee, is to synthesize the available evidence, and to provide practical recommendations. We discuss the evaluation of fever, the indications to obtain cultures including urine, blood, and respiratory specimens for diagnosis of infections, the use of procalcitonin, and the decision to initiate empiric antibiotics. We then describe the treatment of common infections, specifically ventilator-associated pneumonia, catheter-associated urinary infection, catheter-related bloodstream infection, bacteremia, surgical site infection, intra-abdominal infection, ventriculitis, and necrotizing soft tissue infection.

Patterns of drug use among people who inject drugs: A global systematic review and meta-analysis.

BACKGROUND: A better understanding of global patterns of drug use among people who inject drugs can inform interventions to reduce harms related to different use profiles. This review aimed to comprehensively present the geographical variation in drug consumption patterns among this population. METHODS: Systematic searches of peer reviewed (PsycINFO, Medline, Embase) and grey literature published from 2008-2022 were conducted. Data on recent (past year) and lifetime drug use among people who inject drugs were included. Data were extracted on use of heroin, amphetamines, cocaine, benzodiazepines, cannabis, alcohol, and tobacco; where possible, estimates were disaggregated by route of administration (injecting, non-injecting, smoking). National estimates were generated and, where possible, regional, and global estimates were derived through meta-analysis. RESULTS: Of 40,427 studies screened, 394 were included from 81 countries. Globally, an estimated 78.1 % (95 %CI:70.2-84.2) and 71.8 % (65.7-77.2) of people who inject drugs had recently used (via any route) and injected heroin, while an estimated 52.8 % (47.0-59.0) and 19.8 % (13.8-26.5) had recently used and injected amphetamines, respectively. Over 90 % reported recent tobacco use (93.5 % [90.8-95.3]) and recent alcohol use was 59.1 % (52.6-65.6). In Australasia recent heroin use was lowest (49.4 % [46.8-52.1]) while recent amphetamine injecting (64.0 % [60.8-67.1]) and recent use of cannabis (72.3 % [69.9-74.6]) were higher than in all other regions. Recent heroin use (86.1 % [78.3-91.4]) and non-injecting amphetamine use (43.3 % [38.4-48.3]) were highest in East and Southeast Asia. Recent amphetamine use (75.8 % [72.7-78.8]) and injecting heroin use (84.8 % (81.4-87.8) were highest in North America while non-injecting heroin use was highest in Western Europe (45.0 % [41.3-48.7]). CONCLUSION: There is considerable variation in types of drugs and routes of administration used among people who inject drugs. This variation needs to be considered in national and global treatment and harm reduction interventions to target the specific behaviours and harms associated with these regional profiles of use.

An International, Multidisciplinary Consensus Set of Patient-Centered Outcome Measures for Substance-Related and Addictive Disorders.

Background: In 1990, the United States' Institute of Medicine promoted the principles of outcomes monitoring in the alcohol and other drugs treatment field to improve the evidence synthesis and quality of research. While various national outcome measures have been developed and employed, no global consensus on standard measurement has been agreed for addiction. It is thus timely to build an international consensus. Convened by the International Consortium for Health Outcomes Measurement (ICHOM), an international, multi-disciplinary working group reviewed the existing literature and reached consensus for a globally applicable minimum set of outcome measures for people who seek treatment for addiction. Methods: To this end, 26 addiction experts from 11 countries and 5 continents, including people with lived experience (n = 5; 19%), convened over 16 months (December 2018-March 2020) to develop recommendations for a minimum set of outcome measures. A structured, consensus-building, modified Delphi process was employed. Evidence-based proposals for the minimum set of measures were generated and discussed across eight videoconferences and in a subsequent structured online consultation. The resulting set was reviewed by 123 professionals and 34 people with lived experience internationally. Results: The final consensus-based recommendation includes alcohol, substance, and tobacco use disorders, as well as gambling and gaming disorders in people aged 12 years and older. Recommended outcome domains are frequency and quantity of addictive disorders, symptom burden, health-related quality of life, global functioning, psychosocial functioning, and overall physical and mental health and wellbeing. Standard case-mix (moderator) variables and measurement time points are also recommended. Conclusions: Use of consistent and meaningful outcome measurement facilitates carer-patient relations, shared decision-making, service improvement, benchmarking, and evidence synthesis for the evaluation of addiction treatment services and the dissemination of best practices. The consensus set of recommended outcomes is freely available for adoption in healthcare settings globally.

High-grade liver injuries with contrast extravasation managed initially with interventional radiology versus observation: A secondary analysis of a WTA multicenter study.

BACKGROUND: High-grade liver injuries with extravasation (HGLI â€‹+ â€‹Extrav) are associated with morbidity/mortality. For low-grade injuries, an observation (OBS) first-strategy is beneficial over initial angiography (IR), however, it is unclear if OBS is safe for HGLI â€‹+ â€‹Extrav. Therefore, we evaluated the management of HGLI â€‹+ â€‹Extrav patients, hypothesizing IR patients will have decreased rates of operation and mortality. METHODS: HGLI â€‹+ â€‹Extrav patients managed with initial OBS or IR were included. The primary outcome was need for operation. Secondary outcomes included liver-related complications (LRCs) and mortality. RESULTS: From 59 patients, 23 (39.0%) were managed with OBS and 36 (61.0%) with IR. 75% of IR patients underwent angioembolization, whereas 13% of OBS patients underwent any IR, all undergoing angioembolization. IR patients had an increased rate of operation (13.9% vs. 0%, p â€‹= â€‹0.049), but no difference in LRCs (44.4% vs. 43.5%) or mortality (5.6% vs. 8.7%) versus OBS patients (both p â€‹> â€‹0.05). CONCLUSION: Over 60% of patients were managed with IR initially. IR patients had an increased rate of operation yet similar rates of LRCs and mortality, suggesting initial OBS reasonable in appropriately selected HGLI â€‹+ â€‹Extrav patients.

Prevalence and factors associated with polydrug use among clients seeking treatment for alcohol misuse.

INTRODUCTION: The aim of this paper was to examine the client and psychosocial characteristics associated with polydrug use in patients with alcohol misuse as their primary drug of concern (PDC) seeking treatment from substance use treatment centres. METHODS: Self-report surveys were undertaken with clients attending 1 of 34 community-based substance use treatment centres across Australia with alcohol as their PDC. Survey items included client's socio-demographic characteristics, level of alcohol dependence, use of other drugs including tobacco, health and wellbeing factors including health-related quality of life. The factors associated with polydrug use (alcohol use concurrent with at least one other drug) were examined. RESULTS: In a sample of 1130 clients seeking treatment primarily for alcohol problems, 71% reported also using another drug. The most frequently used drug was tobacco (50%) followed by cannabis (21%) and benzodiazepines (15%). Excluding tobacco use, 35% of participants reported polydrug use. Factors associated with any polydrug use were younger age, lower education levels, lower levels of mental health related quality of life and housing risk (i.e., risk of eviction or experienced homelessness in past 4 weeks). When tobacco was excluded, factors associated with polydrug use were age, lower physical and mental health-related quality of life, and housing risk. DISCUSSION AND CONCLUSIONS: Most adults seeking treatment for alcohol misuse as their PDC reported using another drug in addition to alcohol. Treatment services should be designed accordingly to maximise the likelihood of treatment engagement and success.

A core outcome set for acute necrotizing pancreatitis: An Eastern Association for the Surgery of Trauma modified Delphi method consensus study.

BACKGROUND: The management of acute necrotizing pancreatitis (ANP) has changed dramatically over the past 20 years including the use of less invasive techniques, the timing of interventions, nutritional management, and antimicrobial management. This study sought to create a core outcome set (COS) to help shape future research by establishing a minimal set of essential outcomes that will facilitate future comparisons and pooling of data while minimizing reporting bias. METHODS: A modified Delphi process was performed through involvement of ANP content experts. Each expert proposed a list of outcomes for consideration, and the panel anonymously scored the outcomes on a 9-point Likert scale. Core outcome consensus defined a priori as >70% of scores receiving 7 to 9 points and <15% of scores receiving 1 to 3 points. Feedback and aggregate data were shared between rounds with interclass correlation trends used to determine the end of the study. RESULTS: A total of 19 experts agreed to participate in the study with 16 (84%) participating through study completion. Forty-three outcomes were initially considered with 16 reaching consensuses after four rounds of the modified Delphi process. The final COS included outcomes related to mortality, organ failure, complications, interventions/management, and social factors. CONCLUSION: Through an iterative consensus process, content experts agreed on a COS for the management of ANP. This will help shape future research to generate data suitable for pooling and other statistical analyses that may guide clinical practice. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level V.

Brainstem processing of cough sensory inputs in chronic cough hypersensitivity.

BACKGROUND: Chronic cough is a prevalent and difficult to treat condition often accompanied by cough hypersensitivity, characterised by cough triggered from exposure to low level sensory stimuli. The mechanisms underlying cough hypersensitivity may involve alterations in airway sensory nerve responsivity to tussive stimuli which would be accompanied by alterations in stimulus-induced brainstem activation, measurable with functional magnetic resonance imaging (fMRI). METHODS: We investigated brainstem responses during inhalation of capsaicin and adenosine triphosphate (ATP) in 29 participants with chronic cough and 29 age- and sex-matched controls. Psychophysical testing was performed to evaluate individual sensitivities to inhaled stimuli and fMRI was used to compare neural activation in participants with cough and control participants while inhaling stimulus concentrations that evoked equivalent levels of urge-to-cough sensation. FINDINGS: Participants with chronic cough were significantly more sensitive to inhaled capsaicin and ATP and showed a change in relationship between urge-to-cough perception and cough induction. When urge-to-cough levels were matched, participants with chronic cough displayed significantly less neural activation in medullary regions known to integrate airway sensory inputs. By contrast, neural activations did not differ significantly between the two groups in cortical brain regions known to encode cough sensations whereas activation in a midbrain region of participants with chronic cough was significantly increased compared to controls. INTERPRETATION: Cough hypersensitivity in some patients may occur in brain circuits above the level of the medulla, perhaps involving midbrain regions that amplify ascending sensory signals or change the efficacy of central inhibitory control systems that ordinarily serve to filter sensory inputs.

Polypathology-associated neurodegeneration after remote head injury.

Traumatic brain injury (TBI) is a leading cause of morbidity and mortality worldwide. TBI ranges from mild to severe and is a recognized risk factor for later neurodegenerative conditions including chronic traumatic encephalopathy (CTE), Alzheimer disease (AD) and Parkinson disease (PD). The development of CTE is typically associated with repetitive exposure to mild TBI (mTBI), while a single moderate-to-severe TBI is considered a risk factor for AD and PD. Polypathology is common, and the lines between these conditions post TBI can be somewhat blurred. The mechanisms through which TBI leads to future neurodegeneration are not well understood. Heterogeneity and distance from the injury or injuries and individual genetic and environmental factors make clinical studies difficult. We present the case of an 82-year-old man who died 4 years after developing a phenotypically mixed dementia with neuropsychiatric features and parkinsonism. He had a remote history of a severe TBI 40 years prior, following a road traffic accident which caused a large right frontal injury, requiring neurosurgical intervention. Post-mortem neuropathological examination demonstrated abnormal phosphorylated-Tau (p-Tau), beta-amyloid plaques (Aß) and α-synuclein deposition. Spatial immunohistochemical analysis demonstrated increased perivascular accumulation of p-Tau with blood-brain barrier (BBB) disruption at the site of injury, which decreased with distance from the injury site. The appearances are suggestive of initial vascular disruption with persisting BBB disruption as a driver of the pathology.

Meningioma in the elderly.

Meningiomas are the most common primary intracranial neoplasm, accounting for approximately 40% of all primary brain tumors. The incidence of meningioma increases with age to 50 per 100,000 in patients older than 85. As the population ages, an increasing proportion of meningioma patients are elderly. Much of this increase is accounted for by an increase in incidental, asymptomatic diagnoses, which have a low risk of progression in the elderly. The first-line treatment of symptomatic disease is resection. Fractionated radiotherapy (RT) or stereotactic radiosurgery (SRS) can be considered as primary treatment where surgery is not feasible, or as adjuvant therapy in cases of subtotal resection or high grade histopathology. The role of RT/SRS, particularly following gross total resection of atypical meningioma, is unclear and requires further evaluation. There is an increased risk of perioperative and postoperative morbidity in the elderly and therefore management decisions must be tailored to individual circumstances. Good functional outcomes can be achieved in selected patients and age alone is not a contraindication to intervention. The immediate postoperative course is an important determinant of prognosis. Therefore, careful preoperative evaluation and avoidance of complications are necessary to optimize outcomes.

Brain biopsy in neurological disease of unknown etiology: A single-center 12-year retrospective analysis.

There are no international guidelines for brain biopsy in neurological disease of unknown etiology, yet most practicing neurologists will encounter difficult cases in which biopsy is considered. This patient cohort is heterogenous, and it is unclear in which circumstances biopsy is most useful. We performed an audit of brain biopsies reviewed in our neuropathology department from 2010 to 2021. Of 9,488 biopsies, 331 biopsies undertaken for an undiagnosed neurological disease were identified. Where documented, the commonest symptoms were hemorrhage, encephalopathy, and dementia. 29% of biopsies were non-diagnostic. The most common clinically relevant findings on biopsy were infection, cerebral amyloid angiopathy with or without angiitis, and demyelination. Rarer conditions included CNS vasculitis, non-infectious encephalitis, and Creutzfeldt Jakob Disease. We highlight the value of brain biopsy in the workup of cryptogenic neurological disease despite recent advances in less invasive diagnostics.

Characteristics and circumstances of cocaine-related completed suicide in Australia, 2000-2021.

BACKGROUND: There has been a substantial global increase in cocaine use and associated harms. The current study aimed to: 1. Determine the case characteristics and circumstances of death of cocaine-related suicide in Australia 2000-2021; and 2. Determine the toxicological profiles of cases. METHODS: Retrospective study of cocaine-related death in Australia, 2000-2021, retrieved from the National Coronial Information System (NCIS). Suicide intent was based upon the NCIS code for "Intentional Self-harm", derived from case circumstances and coroners' conclusions. Sex comparisons were made for all major variables. RESULTS: A total of 157 cases were identified, 82.2% male, 79.5% employed, with a mean age of 32.3 years. Concerns for mental health were documented in 65.6%, a previous suicide attempt in 21.0%, a history of substance use treatment and/or negative consequences of substance use in 45.9% and injecting drug use in 14.6%. Manner of death amongst both sexes was predominantly by physical means (82.8%). Written intent was documented in 29.3%. Intense agitation prior to the incident was noted in 28.0% and conflict in 24.8%. The median blood cocaine concentration was 0.060 mg/L (range 0.007-5.500). Other drugs were present in 95.5%, most commonly alcohol (63.1%) with a median concentration of 0.140 g/100 ml. Psychostimulants other than cocaine were present in 31.2%. CONCLUSIONS: The 'typical' cocaine-related suicide case was a male, aged in their early thirties, who was highly likely to be employed. The majority of cases used physical means, and a substantial minority were highly agitated and engaged in conflict prior to the fatal incident.

Substance use among vocational trainees in Australia: differences between medical specialties.

BACKGROUND: There have been few large-scale nationally representative studies on the prevalence of substance use among doctors. In addition, the association of different medical specialties with the use of different substances requires further research. AIMS: To investigate how the use of alcohol, tobacco and illicit drugs varied between junior doctors enrolled in different specialty training programmes. METHODS: A secondary analysis was conducted on a national survey of 12 252 Australian doctors. The population of interest was junior doctors currently enrolled in a specialty training programme, termed vocational trainees (VT; n = 1890; 15.4% of the overall sample). Self-report prevalence of current alcohol, tobacco and illicit drug use were assessed and hazardous alcohol use was assessed using the Alcohol Use Disorders Identification Test. Logistic regression was used to examine the association between specialty and substance use, adjusting for demographic characteristics when required. RESULTS: One in six VT reported hazardous levels of alcohol use (n = 268; 17.3%). After adjusting for confounders, the association between the prevalence of alcohol use and the specialties of emergency medicine/intensive care unit (odds ratio (OR) 2.15; 95% confidence interval (CI) 1.40-3.32; P < 0.001), anaesthetics (OR 2.53; 95% CI 1.35-4.76; P = 0.004) and obstetrics/gynaecology (OR 1.89; 95% CI 1.19-3.02; P = 0.007) remained significant. No significant associations were found between tobacco use/illicit drug use/hazardous alcohol use and medical specialty. CONCLUSIONS: While rates of substance use and hazardous alcohol use in VT are similar, if not lower, than the general population, it poses a concern that there are higher rates of alcohol use in certain medical specialties.

Establishing a committee for antemortem reviews of suspect Creutzfeldt-Jakob disease cases in Ireland.

BACKGROUND: Creutzfeldt-Jakob disease (CJD) is a rapidly progressive, neurodegenerative disease. In Ireland, clinical diagnostics and laboratory testing remain the responsibility of the managing clinician and the Neuropathology Department at the Beaumont Hospital, respectively. Centralized review of individual cases is not undertaken. AIMS: To determine how diagnostic processes for CJD could be improved in Ireland and to outline the structure and referral process for a new CJD review panel at the Beaumont Hospital. METHODS: We surveyed Irish neurologists' experiences on the management of CJD in Ireland. We measured turnaround times (TAT) for CSF samples referred for diagnostic CJD testing. Finally, we retrospectively reviewed imaging of autopsy-proven CJD cases to compare with initial reports. RESULTS: Ninety-three percent of neurologists supported a national central review of suspect CJD cases. A second clinical opinion was considered to be of likely benefit by 79%. Additionally, 93% reported that a centralized review of neuroradiology would be useful. All respondents felt that expediting turnaround of CSF analysis would be of benefit. The average TAT for CSF testing was 35.4 days. In retrospective review of imaging, all patients demonstrated MRI findings consistent with CJD. However, in only one of these cases were the initial pre-autopsy radiological findings reported as being consistent with CJD. CONCLUSIONS: These findings support the need for improvements to the Irish National CJD Surveillance Unit to maximize antemortem diagnostic accuracy. On foot of this, a clinical CJD Multidisciplinary Team (CJD MDT) has been established to provide a second opinion on (i) the patient's clinical history, (ii) neuroradiology and (iii) and neurophysiology reports (where available).

A pilot study investigating feasibility of mainstreaming germline BRCA1 and BRCA2 testing in high-risk patients with breast and/or ovarian cancer in three tertiary Cancer Centres in Ireland.

In the Republic of Ireland (ROI), BRCA1/BRCA2 genetic testing has been traditionally undertaken in eligible individuals, after pre-test counselling by a Clinical Geneticist/Genetic Counsellor. Clinical Genetics services in ROI are poorly resourced, with routine waiting times for appointments at the time of this pilot often extending beyond a year. The consequent prolonged waiting times are unacceptable where therapeutic decision-making depends on the patient's BRCA status. "Mainstreaming" BRCA1/BRCA2 testing through routine oncology/surgical clinics has been implemented successfully in other centres in the UK and internationally. We aimed to pilot this pathway in three Irish tertiary centres. A service evaluation project was undertaken over a 6-month period between January and July 2017. Eligible patients, fulfilling pathology and age-based inclusion criteria defined by TGL clinical, were identified, and offered constitutional BRCA1/BRCA2 testing after pre-test counselling by treating clinicians. Tests were undertaken by TGL Clinical. Results were returned to clinicians by secure email. Onward referrals of patients with uncertain/pathogenic results, or suspicious family histories, to Clinical Genetics were made by the treating team. Surveys assessing patient and clinician satisfaction were sent to participating clinicians and a sample of participating patients. Data was collected with respect to diagnostic yield, turnaround time, onward referral rates, and patient and clinician feedback. A total of 101  patients underwent diagnostic germline BRCA1/BRCA2 tests through this pathway. Pathogenic variants were identified in 12 patients (12%). All patients in whom variants were identified were appropriately referred to Clinical Genetics. At least 12 additional patients with uninformative BRCA1/BRCA2 tests were also referred for formal assessment by Clinical Geneticist or Genetic Counsellor. Issues were noted in terms of time pressures and communication of results to patients. Results from a representative sample of participants completing the satisfaction survey indicated that the pathway was acceptable to patients and clinicians. Mainstreaming of constitutional BRCA1/BRCA2 testing guided by age- and pathology-based criteria is potentially feasible for patients with breast cancer as well as patients with ovarian cancer in Ireland.

Household Composition and Smoking Behavior in a Prospective Longitudinal Australian Cohort.

INTRODUCTION: This study estimates the extent to which individuals' smoking cessation and relapse patterns are associated with the smoking behavior of their household members. AIMS AND METHODS: Longitudinal data on household members' smoking behavior was sourced from a representative sample of 12 723 Australians who ever reported smoking between 2001 and 2019. Controlling for a rich set of confounders, multivariate regression analyses were used to predict the likelihood of smoking cessation and relapse given other household members' smoking status and their relationship type. The models were then used to forecast smoking prevalence over 10 years across different household types. RESULTS: Individuals living with a smoking spouse were less likely to quit (OR 0.77 [95% CI 0.72;0.83]) and more likely to relapse (OR 1.47 [95% CI 1.28;1.69]) compared to those living with nonsmoking spouses. Subsequently, the proportion of smokers living with other smoking household members increased by 15% between 2011 and 2019. A 10-year forecast using the smoking cessation and relapse models predicts that, on average, smokers living with nonsmokers will reduce by 43%, while those living alone or with a smoking partner will only reduce by 26% and 28% respectively. CONCLUSIONS: Over time, those who are still smoking are more likely to live with other smokers. Therefore, the current cohort of smokers is increasingly less likely to quit and more likely to relapse. Smoking projection models that fail to account for this dynamic risk may overstate the downstream health benefits and health cost savings. Interventions that encourage smoking cessation at the household level, particularly for spouses, may assist individuals to quit and abstain from smoking. IMPLICATIONS: The current and future paradigm shift in the smoking environment suggests that smoking cessation and relapse prevention policies should consider household structure. Policies designed to affect smoking at the household level are likely to be particularly effective. When estimating the long-term benefits of current smoking policies intrahousehold smoking behavior needs to be considered.

Uptake of BRCA1/BRCA2 predictive genetic testing in an Irish population is low: a missed opportunity.

INTRODUCTION: Predictive testing for BRCA1 or BRCA2 allows at-risk individuals to engage with appropriate screening and treatment services if a pathogenic mutation is identified. Previous studies have shown uptake of predictive testing to most commonly range between 20% and 40% (Table 2). This represents a missed cancer prevention opportunity. Possible explanations for this low uptake include lack of disclosure of at-risk status to relatives, lack of awareness of cancer genetics services, or patient preference. The goal of the current study was to investigate the uptake of BRCA1 or BRCA2 predictive testing in an Irish population. METHODS: We performed a multicentre, retrospective analysis of 63 pedigrees from two Irish tertiary referral hospitals over a five-year period (2012-2017). Family pedigrees were reviewed to identify at-risk family members eligible for predictive BRCA1 or BRCA2 mutation testing as per international guidelines, and testing rates were determined. RESULTS: A total of 1048 eligible individuals were identified, 318 (30.4%) proceeded to BRCA1 or BRCA2 germline testing including [215 (37.5%) females and 99 males (21.5%)]. Women were significantly more likely to test than men (T = 3.7, p < .0002). Uptake of testing was significant higher amongst first-degree relatives 45% (150/323) compared to 20% (50/258) amongst second degree relatives, and 10 % (33/317) amongst more distant relatives (F = 25.32, p < 0.00001). CONCLUSIONS: Uptake of BRCA1 OR BRCA2 mutation testing in Ireland is suboptimal, particularly amongst Irish males and distant relatives. Further research is needed to identify strategies which may improve uptake within current legal and ethical frameworks.

An observation-first strategy for liver injuries with "blush" on computed tomography is safe and effective.

INTRODUCTION: The management of liver injuries in hemodynamically stable patients is variable and includes primary treatment strategies of observation (OBS), angiography (interventional radiology [IR]) with angioembolization (AE), or operative intervention (OR). We aimed to evaluate the management of patients with liver injuries with active extravasation on computed tomography (CT) imaging, hypothesizing that AE will have more complications without improving outcomes compared with OBS. METHODS: This is a prospective, multicenter, observational study. Patients who underwent CT within 2 hours after arrival with extravasation (e.g., blush) on imaging were included. Exclusion criteria included cirrhosis, nontraumatic hemorrhage, transfers from outside facilities, and pregnancy. No hemodynamic exclusion criteria were used. The primary outcome was liver-specific complications. Secondary outcomes include length of stay and mortality. Angioembolization patients were compared with patients treated without AE. Propensity score matching was used to match based on penetrating mechanism, liver injury severity, arrival vital signs, and early transfusion. RESULTS: Twenty-three centers enrolled 192 patients. Forty percent of patients (n = 77) were initially OBS. Eleven OBS patients (14%) failed nonoperative management and went to IR or OR. Sixty-one patients (32%) were managed with IR, and 42 (69%) of these had AE as an initial intervention. Fifty-four patients (28%) went to OR+/- IR. After propensity score matching (n = 34 per group), there was no difference in baseline characteristics between AE and OBS. The AE group experienced more complications with a higher rate of IR-placed drains for abscess or biloma (22% vs. 0%, p = 0.01) and an increased overall length of stay ( p = 0.01). No difference was noted in transfusions or mortality. CONCLUSION: Observation is highly effective with few requiring additional interventions. Angioembolization was associated with higher rate of secondary drain placement for abscesses or biloma. Given this, a trial of OBS and avoidance of empiric AE may be warranted in hemodynamically stable, liver-injured patient with extravasation on CT. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level II.
