Comparative Outcomes for Trauma Patients in Prison and the General Population.

BACKGROUND: Prisoners are a vulnerable population, and there are few contemporary studies that consider trauma patient outcomes within the prisoner population. Therefore, we sought to provide a descriptive analysis of prisoners involved in trauma and evaluate whether a healthcare disparity exists. We hypothesized that prisoners and non-prisoners have a similar risk of mortality and in-hospital complications after trauma. METHODS: The Trauma Quality Improvement Program (2015-2016) was queried for trauma patients based upon location inside or outside of prison at the time of injury. A multivariable logistic regression analysis was performed to compare these groups for risk of mortality-the primary outcome. RESULTS: From 593,818 trauma patients, 1115 were located in prison. Compared to non-prisoners, prisoner trauma patients had no significant difference in mortality (5.1 vs 6.0%, P = .204). However, after adjusting for covariates, prisoners had a shorter length of stay (LOS) (mean days, 6.3 vs 7.8, P < .001), shorter intensive care unit (ICU) LOS (mean days, 5.44 vs 5.89, P = .004), and fewer complications, including lower rates of drug/alcohol withdrawal (.4% vs 1.1%, P = .030), pneumonia (.5 vs 1.6%, P = .004), and urinary tract infections (.0 vs 1.1%, P < .001). Upon performing a multivariable logistic regression model, prisoner trauma patients had a similar associated risk of mortality compared to non-prisoners (OR 1.61, CI .52-4.94, P = .409). DISCUSSION: Our results suggest that prisoner trauma patients at least receive equivalent treatment in terms of mortality and may have better outcomes when considering some complications. Future prospective studies are needed to confirm these results and explore other factors, which impact prisoner patient outcomes.

Viscoelastic hemostatic fibrinogen assays detect fibrinolysis early.

PURPOSE: Viscoelastic hemostatic assays are emerging as the standard-of-care in the early detection of post-injury coagulopathy. TEG and ROTEM are most commonly used. Although similar in technique, each uses different reagents, which may affect their sensitivity to detect fibrinolysis. Therefore, the purpose of this study is to determine the ability of each device to detect fibrinolysis. METHODS: TEG (Rapid, Kaolin, Functional Fibrinogen) and ROTEM (EXTEM, INTEM, FIBTEM) were run simultaneously on normal blood as well as blood containing tPA from healthy volunteers (n = 10). A two-tailed, paired t-test and ANOVA were used to determine the significance between parameters obtained from normal blood and blood with tPA, and individual TEG and ROTEM assays, respectively. RESULTS: TEG detected significant changes in clot strength and 30-min lysis after the addition of tPA (p < 0.0001). All ROTEM assays detected changes in the 30-min lysis (p < 0.0001), but only INTEM detected changes in clot strength (p < 0.05). Kaolin and Rapid TEG assays detected greater changes in clot strength and lysis, but INTEM and EXTEM had decreased lysis onset times compared to TEG (p < 0.001). Functional Fibrinogen and FIBTEM assays detected lysis sooner than other TEG/ROTEM assays, and were comparable. CONCLUSIONS: TEG assays detect greater changes in clot strength compared to ROTEM. Despite this, Functional Fibrinogen and FIBTEM assays detect fibrinolysis sooner than their corresponding intrinsic and extrinsic assays. Therefore, fibrinogen assays should be employed in actively bleeding trauma patients in order to provide timely antifibrinolytic therapy.

Viral infections in pregnancy: advice for healthcare workers.

BACKGROUND: Healthcare workers (HCWs) have the potential for increased exposure to infectious disease resulting from the provision of patient care. Pregnancy can confer specific problems in some infections for the mother and her unborn child. AIMS: To discuss the viral infections encountered in the UK that constitute a particular risk to the pregnant HCW: human immunodeficiency virus, hepatitis B virus, hepatitis C virus, varicella-zoster virus, herpes simplex virus, human parvovirus B19, cytomegalovirus, rubella, measles, enteroviruses, mumps and influenza. Evidence for nosocomial transmission, clinical aspects specific to pregnancy, and recommendations to protect the pregnant HCW at work are included. METHODS: Medline, EMBASE and Pubmed were searched using a list of keywords specific to each viral infection, including 'nosocomial', 'occupational' and 'healthcare workers'. References from the bibliographies of articles identified were reviewed for relevant material. FINDINGS: The evidence for increased risk in the healthcare setting for many of these infections, outside of outbreaks, is weak, possibly because of the application of standard protective infection control measures or because risk of community exposure is greater. The pregnant HCW should be advised on protective behaviour in both settings. Potential interventions include vaccination and reducing the likelihood of exposure through universal precautions, infection control and redeployment. CONCLUSION: Protection of the pregnant HCW is the responsibility of the individual, antenatal care provider and employer, and is made possible through awareness of the risks and potential interventions both before and after exposure. If exposure occurs or if the HCW develops an infective illness, urgent specialist advice is required.
