However, the ways in which immediate pre-injury substance use affects patients' clinical care and outcomes remains unclear. The goal of the present study is to determine the associations between pre-injury use of alcohol or drugs and patient injury severity, hospital course, and clinical outcome.
Materials and methods: This study used more than 200,000 records from the National Trauma Data Bank (NTDB), which is the largest trauma registry in the United States. Incidents in the NTDB were placed into one of four classes: alcohol related, drug related, alcohol-and-drug related, and substance negative. Logistic regression models were used to determine comorbid conditions or treatment complications that were significantly associated with pre-injury substance use. Hospital charges were associated with the presence or absence of drugs and alcohol, and patient outcomes were assessed using discharge disposition as delimited by the NTDB.
Results: The rates of complications arising during treatment were 8.3, 10.9, 9.9 and 8.6 per one hundred incidents in the alcohol related, drug related, alcohol-and-drug related, and substance-negative classes, respectively. Regression models suggested that pre-injury alcohol use is associated with a 15% higher risk of infection, whereas pre-injury drug use is associated with a 30% higher risk of infection. Pre-injury substance use did not appear to significantly impact clinical outcomes following treatment for traumatic injury, however.
Conclusion: This study suggests that pre-injury drug use is associated with a significantly higher complication rate. In particular, infection during hospitalization is a significant risk for both alcohol and drug related trauma visits, and drug-related trauma incidents are associated with increased risk for additional circulatory complications. Although drug and alcohol related trauma incidents are not associated with appreciably worse clinical outcomes, patients experiencing such complications are associated with significantly greater length of stay and higher hospitalization costs. Therefore significant benefits to trauma patients could be gained with enhanced surveillance for pre-injury substance use upon admission to the ED, and closer monitoring for infection or circulatory complications during their period of hospitalization.Center for Systems and Synthetic [email protected]
Jack-of-all-trades, master of none: Postgraduate perspectives on interdisciplinary health research in Australia
BACKGROUND: Interdisciplinary health research is increasingly perceived as an expectation of research institutions and funding bodies within Australia. However, little consideration has been given to the extent to which this re-orientation has produced a new type of researcher – an interdisciplinary health researcher. DISCUSSION: As cross-enrolled postgraduate research students, we assert that we do not have an intellectual home. Rather, we must forge a virtual intellectual home through the process of bridging disciplines. In this paper we explain that this virtual home affords us the role of 'interlockers' in future health research. The interlocker role privileges a breadth of understandings across disciplines, rather than a depth in one. SUMMARY: We conclude by reiterating that there is an undeniable need for interdisciplinary health research, and that the roles and actions of interdisciplinary health researchers need to be better understood and catered for. We therefore call for increased consideration and discussion concerning the future roles and capacities of interdisciplinary health researchers such as ourselves
Vampires in the village Žrnovo on the island of Korčula: following an archival document from the 18th century
Središnja tema rada usmjerena je na raščlambu spisa pohranjenog u Državnom arhivu u Mlecima (fond: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) koji se odnosi na događaj iz 1748. godine u korčulanskom selu Žrnovo, kada su mještani – vjerujući da su se pojavili vampiri – oskvrnuli nekoliko mjesnih grobova. U radu se podrobno iznose osnovni podaci iz spisa te rečeni događaj analizira u širem društvenom kontekstu i prate se lokalna vjerovanja.The main interest of this essay is the analysis of the document from the State Archive in Venice (file: Capi del Consiglio de’ Dieci: Lettere di Rettori e di altre cariche) which is connected with the episode from 1748 when the inhabitants of the village Žrnove on the island of Korčula in Croatia opened tombs on the local cemetery in the fear of the vampires treating.
This essay try to show some social circumstances connected with this event as well as a local vernacular tradition concerning superstitions
The WAM score: Sensitivity and specificity of a user friendly biological screening test for alcohol problems in trauma patients
Based on a weighted aggregation of three biological alcohol markers (gamma-glutamyltransferase, blood alcohol and mean corpuscular volume), this study presents a screening instrument for alcohol problems in trauma patients. The sex-specific performance of this instrument was explored on 1088 male and 352 female patients, 18 years or older, admitted with blunt or penetrating trauma during a 30-month period to a regional level one trauma center in Seattle, Washington (USA). The sum of the differentially weighted alcohol markers ( WAM ), determined from one blood sample, formed a score continuum ranging from 0 to 24. The WAM scores distributed themselves across the trauma population with higher WAM scores being correlated to higher screening instrument scores for alcohol problems. By using two of the best established screening tests for alcohol problems (CAGE and SMAST) to define cut-off points for likely alcohol abuse/dependence , the WAM score of ≥ 7 in males showed 75% sensitivity and 83% specificity, whereas the WAM score of ≥ 6 for females displayed 85% sensitivity and 85% specificity. We conclude that a weighted combination of biological alcohol markers (WAM score) is a useful tool for identifying alcohol problems among trauma patients. Representing an alternative or addition to a more extensive interview, it could be used as a routine part of the care of trauma patients
The cage questionnaire and the short michigan alcohol screening test in trauma patients: Comparison of their correlations with biological alcohol markers
Study Objectives: To explore and compare the sex-specific correlation of two standard behavioral screening instruments, the Short Michigan Alcohol Screening Test (SMAST) and the CAGE, with a weighted scale that combines the three most commonly used biological alcohol markers (blood alcohol level, mean corpuscular volume, and gamma-glutamyltransferase level). Design: A prospective cohort study. Setting: Regional level I trauma center, in Seattle, Washington. Participants: 1980 male and 602 female patients 18 years of age or older, admitted with blunt or penetrating trauma. Main Results: Spearman rank correlations were used to compare the two screening measures with the weighted scale. The CAGE was found to correlate better than the SMAST with the weighted combination. Correlations for both measures were higher in women than in men. Among the individual biological alcohol markers used to construct the weighted scale, blood alcohol level was the marker that displayed the strongest correlation with both the CAGE and the SMAST. Conclusion-. We conclude that the CAGE questionnaire showed a higher correlation with a combination of biological alcohol markers than did the SMAST, and that the CAGE may be the questionnaire of choice for identification of alcohol problems in patients seen in trauma centers. © 1994 by Williams & Wilkins
