Abstract
Background Many persons with dementia transition to nursing home care, but little is known about the impact, positive and negative, that this may have on the social isolation and loneliness of their spouse. Methods Using our existing theoretical synthesis of loneliness to provide sensitising concepts, we conducted a deductive grounded theory study of loneliness during the nursing home transitions. We recruited 11 spousal participants to engage in semi-structured remote interviews during 2021. Results Participants provided their own definitions of loneliness, and spoke about their life history of loneliness, the loneliness associated with living with a spouse with dementia, and the loneliness, and alleviation of loneliness through re-engagement with social contacts, associated with their spouse moving to the nursing home. Participants agreed with the idea that loneliness has a physical feeling. More distal parts of the theoretical synthesis, such as the influence that culture and gender have on loneliness, were not corroborated by the findings. Conclusion We conclude that loneliness is a frequent experience among spousal caregivers whose spouse has moved to nursing home care, but that loneliness is also associated with living with a spouse with dementia. Loneliness in this population was aggravated by the COVID-19 pandemic and associated lockdowns. Further research steps will involve more targeted interviewing to focus on the link between transitions and loneliness in this and in other populations.

Abstract
The EUFORA fellowship programme ‘Livestock Health and Food Chain Risk Assessment’ was proposed by the Animal and Plant Health Agency (APHA), a British governmental institution responsible for safeguarding animal and plant health in the UK. The working programme, which was organised into four different modules, covered a wide range of aspects related to risk assessment including identification of emerging risks, risk prioritisation methods, scanning surveillance, food production exposure assessment and import risk assessment of animal and human infectious diseases. Over the course of the year, the Fellow had the opportunity to work for international projects with experts in these disciplines. This allowed for significant opportunities to ‘learn‐by‐doing’ the methods and the techniques that are employed to assess animal health and food safety risks. Moreover, he consolidated his knowledge by attending several training courses and academic lessons, submitting scientific papers to peer‐reviewed journals and conferences, giving presentations and using modelling software.

Abstract
BACKGROUND Acute care injury outcomes vary substantially across Canadian provinces and trauma centres. Our aim was to develop Canadian benchmarks to monitor mortality and hospital length of stay (LOS) for injury admissions. METHODS Benchmarks were derived using data from the Canadian National Trauma Registry on patients with major trauma admitted to any level I or II trauma centre in Canada and from the following patient subgroups: isolated traumatic brain injury (TBI), isolated thoracoabdominal injury, multisystem blunt injury, age 65 years or older. We assessed predictive validity using measures of discrimination and calibration, and performed sensitivity analyses to assess the impact of replacing analytically complex methods (multiple imputation, shrinkage estimates and flexible modelling) with simple models that can be implemented locally. RESULTS The mortality risk adjustment model had excellent discrimination and calibration (area under the receiver operating characteristic curve 0.886, Hosmer-Lemeshow 36). The LOS risk-adjustment model predicted 29% of the variation in LOS. Overall, observed:expected ratios of mortality and mean LOS generated by an analytically simple model correlated strongly with those generated by analytically complex models (r > 0.95, κ on outliers > 0.90). CONCLUSION We propose Canadian benchmarks that can be used to monitor quality of care in Canadian trauma centres using Excel (see the appendices, available at canjsurg.ca). The program can be implemented using local trauma registries, providing that at least 100 patients are available for analysis.

Abstract
Importance In response to the burden of injury, the structure of injury care has changed considerably across Canada in the past decade. However, little is known about how patient outcomes have evolved. Objective To evaluate trends in mortality, hospital length of stay, and unplanned readmission in Canadian trauma systems between 2006 and 2012. Design, Setting, and Participants A pan-Canadian retrospective cohort study was conducted among adults admitted for major injury to a Canadian level I or II trauma center between April 1, 2006, and March 31, 2012. Data analysis was conducted from April 15 to December 3, 2015. Exposures Trauma centers and systems. Main Outcomes and Measures Multilevel generalized linear models were used to evaluate trends in the risk-adjusted incidence of mortality and readmission and risk-adjusted mean length of stay. Trend analyses were conducted globally and by province. Results Among 78 807 patients (mean [SD] age, 50.7 [22.0] years; 22 540 women and 56 267 men) admitted for major injury during the study period, risk-adjusted mortality decreased from 12.1% (95% CI, 9%-16.1%) to 9.9% (95% CI, 7.4%-13.3%; P < .001) and mean length of hospital stay decreased from 11.6 (95% CI, 9.9-13.6) to 10.6 (95% CI, 9.1-12.5) days (P < .001). Statistically significant reductions in mortality were observed for Ontario (12% [95% CI, 10.7%-13.6%] to 8% [95% CI, 6.9%-9.2%]; P < .001), Alberta (12% [95% CI, 10%-14.3%] to 9.1% [95% CI, 7.7%-10.8%]; P = .02), and Manitoba (13% [95% CI, 9.1%-18.4%] to 11.1% [95% CI, 8.3%-14.7%]; P = .04). Risk-adjusted hospital stay decreased significantly in Québec (11.6 [95% CI, 11.1-12] to 9.1 [95% CI, 8.9-9.5] days; P < .001), British Columbia (12.5 [95% CI, 12-13.1] to 11.4 [10.9-11.9] days; P < .001), and Ontario (10.1 [95% CI, 9.8-10.4] to 9.8 [95% CI, 9.5-10.1] days; P < .001). No change in the incidence of readmission was observed. Conclusions and Relevance We observed an 18.2% relative decrease in risk-adjusted mortality in Canadian trauma centers during the study period, representing 248 additional lives saved in 2012 vs 2006. Risk-adjusted mean hospital stay decreased by 8.6%, representing nearly 10 000 hospital days saved. A better understanding of the structures and processes behind observed improvements is needed to further reduce the burden of injury in Canada.

Abstract
IMPORTANCE The rate of complications among injury admissions has been estimated to be more than 3 times that observed for general admissions, and complications have been targeted as an important quality-of-care metric. Despite the negative effect of complications on resource use and patient mortality and morbidity, there is no standardized method to benchmark trauma centers in terms of in-hospital complications, to our knowledge. OBJECTIVES To develop a quality indicator (QI) for in-hospital complications that can be used to evaluate the quality of acute injury care and to assess its validity. DESIGN, SETTING, AND PARTICIPANTS Multicenter retrospective cohort study. The setting was a well-established inclusive trauma system in Canada. Participants included all 66 048 moderate or major injury admissions to an adult trauma center between April 1, 2006, and March 31, 2012. The dates of the analysis were January to April 2015. MAIN OUTCOMES AND MEASURES The primary outcome was the occurrence of at least 1 in-hospital complication. We selected risk-adjustment variables by expert consultation and bootstrap resampling. We evaluated internal validity using measures of discrimination, construct validity, and forecasting. RESULTS The study cohort comprised 66 048 patients. Their mean (SD) age was 59 (22) years, and 48.0% were female. Fifteen percent of patients had at least 1 in-hospital complication. The risk-adjustment model has excellent discrimination (area under the curve, 0.81) and calibration. The QI was correlated with the risk-adjusted incidence of mortality (r = 0.71), unplanned readmission (r = 0.43), and mean length of stay (r = 0.68). Hospital performance on the QI from 2007 to 2009 was predictive of performance from 2010 to 2012 (r = 0.82). CONCLUSIONS AND RELEVANCE We developed a QI to benchmark trauma centers on in-hospital complications among injury admissions. The QI is based on data that are routinely collected in most trauma systems and demonstrates good internal validity. The integration of this QI in trauma quality improvement programs will facilitate the identification of quality problems, the implementation of solutions, and the evaluation of their effectiveness. Therefore, the QI has the potential to lead to reductions in mortality, morbidity, and resource use after injury.

Abstract
ABSTRACT
Background:
Alcohol is a frequent contributing factor to motor vehicle collision injuries. Our objective was to determine the proportion of intoxicated drivers hospitalized following motor vehicle crashes who were subsequently convicted of an impaired driving criminal code offence.
Methods:
We reviewed British Columbia Trauma Registry records from Jan. 1, 1992, to Mar. 31, 2000, and identified drivers of motor vehicles who were hospitalized for treatment of crash-related injuries. Patient identifiers were then used to link with the Insurance Corporation of British Columbia’s (ICBC) contraventions database and the ICBC Traffic Accident System collisions database.
Results:
Of 6067 patients identified in the Trauma Registry, 4042 had not been administered a blood ethanol test, 209 had no driver’s licence match in the relevant databases and 119 died, leaving 1697 eligible patients. Mean age was 34 years, and 79.6% were male. The average Injury Severity Score was 20, the average hospital stay was 14 days and, among ethanol-positive patients, the mean ethanol level was 34.0 mmol/L (156.4 mg/dL). In patients with levels >17.3 mmol/L, the police had listed ethanol as a contributing factor in 70.6% of cases. Despite this, only 11.0% were convicted of impaired driving and 8.4% of another criminal offence; 10.7% received a 24-hour roadside prohibition, 3.9% received a 90-day administrative driving prohibition and 25.0% were convicted of a contravention of the Motor Vehicle Act. Forty-one percent were not convicted of any offence at all.
Conclusions:
Intoxicated drivers in British Columbia requiring hospitalization as a result of alcohol-related motor vehicle crashes are seldom convicted of impaired driving or other criminal code offences.

Abstract
This work presents a validated optical fluence rate model optimised for ultraviolet light-emitting diodes (UV-LEDs), which allow a very wide range of emission wavelengths and source geometries to be used in water treatment units. The model is based on a Monte Carlo approach, in which an incremental ray-tracing algorithm is used to calculate the local volumetric rate of energy absorption and subsequently convert it to the local fluence rate distribution for an UV-LED water treatment chamber of arbitrary design. The model includes contributions from optical reflections and scattering by treatment chamber walls and from scattering due to particulates and/or microorganisms. The model successfully predicts optical fluence rates in point-of-use water treatment units, as verified using biodosimetry with MS-2 bacteriophage at a UV-LED emission wavelength of 254 nm. The effects of chamber geometry are also modelled effectively and are consistent with the inactivation data for E. coli at 254 nm. The data indicate that this model is suitable for application in the design and optimisation of UV-LED-based water treatment systems.

Abstract
BACKGROUND In Canada and the United States, research has shown that injured patients initially treated at smaller emergency departments before transfer to larger regional facilities are more likely to require longer stays in hospital or suffer greater mortality. It remains unknown whether transport status is an independent predictor of adverse health events among persons requiring care from provincial burn centres. METHODS We obtained case records from the British Columbia Trauma Registry for adult patients (age ≥ 18 yr) referred or transported directly to the Vancouver General Hospital and Royal Jubilee Hospital burn centres between Jan. 1, 2001, and Mar. 31, 2006. Prehospital and in-transit deaths and deaths in other facilities were identified using the provincial Coroner Service database. Place of injury was identified through data linkage with census records. We performed bivariate analysis for continuous and discrete variables. Relative risk (RR) of prehospital and in-hospital mortality and hospital stay by transport status were analyzed using a Poisson regression model. RESULTS After controlling for patient and injury characteristics, indirect referral did not influence RR of in-facility death (RR 1.32, 95% confidence interval [CI] 0.54- 3.22) or hospital stay (RR 0.96, 95% CI 0.65-1.42). Rural populations experienced an increased risk of total mortality (RR 1.22, 95% CI 1.00-1.48). CONCLUSION Transfer status is not a significant indicator of RR of death or hospital stay among patients who received care at primary care facilities before transport to regional burn centres. However, significant differences in prehospital mortality show that improvements in rural mortality can still be made.

Abstract
The 2003-2005 Confidential Enquiry into Maternal and Child Health report recommended the introduction of the modified early obstetric warning system (MEOWS) in all obstetric inpatients to track maternal physiological parameters, and to aid early recognition and treatment of the acutely unwell parturient. We prospectively reviewed 676 consecutive obstetric admissions, looking at their completed MEOWS charts for triggers and their notes for evidence of morbidity. Two hundred patients (30%) triggered and 86 patients (13%) had morbidity according to our criteria, including haemorrhage (43%), hypertensive disease of pregnancy (31%) and suspected infection (20%). The MEOWS was 89% sensitive (95% CI 81-95%), 79% specific (95% CI 76-82%), with a positive predictive value 39% (95% CI 32-46%) and a negative predictive value of 98% (95% CI 96-99%). There were no admissions to the intensive care unit, cardio respiratory arrests or deaths during the study period. This study suggests that MEOWS is a useful bedside tool for predicting morbidity. Adjustment of the trigger parameters may improve positive predictive value.

Abstract
BACKGROUND Evidence-based practice (EBP) is a generally accepted means to improve healthcare quality. However, not all healthcare professionals and managers apply EBP in daily practice. We investigated EBP attitudes, knowledge and the perceived barriers and facilitators to practising EBP , to define tailor-made interventions for improving evidence-based behaviour. METHODS In this cross-sectional survey, doctors and nurses from five major specialities of a university hospital were invited to complete the McColl and Barriers questionnaires. RESULTS Response rates were 70% (305÷435) for doctors and 74% (396÷537) for nurses. They were welcoming towards EBP, but considered time constraints, knowledge gaps and poor availability of evidence as major barriers to implement EBP . They also mentioned contradicting results (75%) and flawed methodology (69%), while nurses frequently mentioned unawareness of (75%), or difficulty in reading and interpreting research papers (70%). Regarding EBP knowledge, 6/8 common EBP terms could be explained by 54% of doctors but by only 15% of nurses. Facilitating factors among doctors concerned the availability and accessibility of high-level evidence and communication of evidence during various clinical meetings and handovers for clinical decision making. Among nurses, promoting factors involved more teaching and instances to incorporate EBP in clinical practice. Both groups desired more managerial support in terms of motivation and opportunities. CONCLUSIONS Doctors and nurses have embraced the EBP paradigm as an important means to improve quality of clinical patient care, but its application is still cumbersome. This paper offers a tailored programme for implementation and managerial role-models.sustainment of EBP, corroborated by professional and managerial role-models.

Abstract
OBJECTIVE We determined the rate of, and predictive factors for, subsequent impaired driving activity (IDA) by injured drivers treated in a Canadian tertiary care emergency department (ED) following a motor vehicle crash (MVC). METHODS We retrospectively identified all drivers injured in a MVC who presented to our tertiary care, urban ED (1999-2003) and had their blood alcohol content (BAC) measured. Injured drivers were categorized by BAC: group 1, BAC = 0; group 2, 0 < BAC < or = 17.3 mM (80 mg/dL, legal limit); and group 3, BAC > 17.3 mM. IDA was defined as any of the following: a conviction for impaired driving; a 24-h or 90-day license suspension for impaired driving; involvement in alcohol-related MVC. Time to IDA following the index event between groups was compared with Kaplan-Meier survival analyses. Effects of covariates on time to IDA were analyzed using Cox proportional hazards models. RESULTS During the study period, 1489 injured drivers met study criteria: 1171 in group 1, 51 in group 2, and 267 in group 3. During an average follow-up of 52.4 months, 82 (30.7%) group 3 drivers engaged in subsequent IDA, compared with 80 (6.8%) group 1 drivers (p < 0.0001). Youth, male gender, history of previous IDA, and the number of previous IDA events were all associated with a significant increase in subsequent IDA. A history of IDA was the strongest predictor of future IDA in group 1 (440% increase risk) and in group 3 (80% increased risk). The magnitude of BAC elevation above the legal limit was not predictive of future IDA. CONCLUSIONS A high portion of injured impaired drivers who present to hospital engage in repeat IDA following discharge. Besides impairment at time of hospital visit, the best predictor of future IDA is a history of IDA prior to the index event.

Abstract
BACKGROUND The centrifugal vortex blood pump (CVBP) using heparin-bonded circuitry allows re-warming of hypothermic trauma patients without anticoagulation. Study objectives were to confirm efficacy, and to characterise the physiology of CVBP re-warming in a porcine model. METHODS Sixteen pigs were randomised to conventional or CVBP re-warming. They were bled to a mean arterial pressure of 30 mmHg and cooled to 29 degrees C. A physiological analysis was recorded during resuscitation to normo-tension and re-warming back to 37 degrees C. RESULTS CVBP animals re-warmed significantly faster: 85.0+16.4 min versus 217.4+49.3 min (p<0.0001). Activated clotting time was significantly elevated in both groups at 29 degrees C with a marked trend to normalise faster in CVBP pigs. The peak cardiac index (CI) was significantly lower (1.14+0.68 versus 4.83+1.50 L/(min m2), while the systemic vascular resistance (SVR) was significantly higher (4239.9+1173.0 versus 1472.6+451.2 dyn x S x m2/cm5) with CVBP (p<0.001). CONCLUSION CVBP is simple and very effective at re-warming hypothermic animals and may also reverse coagulopathy more quickly. Physiological derangements of elevated SVR and diminished CI require further study to elaborate underlying aetiology, and define optimal re-warming strategies.

Abstract
BACKGROUND Benchmarks are used in trauma care for program evaluation, quality improvement, and research. National outcome benchmarks relevant to the Canadian trauma population need to be defined for evaluation of trauma care in Canada. The purpose of this study was to derive survival probabilities associated with trauma diagnoses using International Classification of Diseases, Ninth Revision (ICD-9) codes. METHODS All patients admitted to an acute care hospital with nonpenetrating trauma and submitted to the National Trauma Registry of Canada between 1994 through 2000 inclusively were included in analyses. Both inclusive and exclusive survival risk ratios (SRRs) were calculated for groups of ICD-9 injury codes between 800 to 959. RESULTS For the study period, there were 1,003,905 and 803,776 eligible trauma patients used to calculate inclusive SRRs and exclusive SRRs, respectively. Survival probabilities for injuries are given according to ICD-9 codes. CONCLUSION This is the first study to define national survival benchmarks for the Canadian trauma population. These results can be used to assess survival of patients using the ICISS [(ICD-9) based Injury Severity Score (ISS)] methodology. With regular updates, these data can further be developed for continual trauma outcome assessment, quality improvement, and research into trauma care in Canada.

Abstract
The aim of this study was to evaluate the effect of increasing epinephrine load on the characteristics of fast-disintegrating sublingual tablets for the potential emergency treatment of anaphylaxis. Four tablet formulations, A, B, C, and D, containing 0%, 6%, 12%, and 24% of epinephrine bitartrate, respectively, and microcrystalline cellulose:low-substituted hydroxypropyl cellulose (9:1), were prepared by direct compression, at a range of compression forces. Tablet weight variation, content uniformity, hardness, disintegration time, wetting time, and friability were measured for each formulation at each compression force. All 4 tablet formulations at each compression force were within the United States Pharmacopeia (USP) limits for weight variation and content uniformity. A linear increase in compression force resulted in an exponential increase in hardness for all formulations, a linear increase in disintegration and wetting times of A, and an exponential increase in disintegration and wetting times of B, C, and D. At a mean +/- SD hardness of > or = 2.3 +/- 0.2 kg, all tablet formulations passed the USP friability test. At a mean +/- SD hardness of < or = 3.1 +/- 0.2 kg, all tablet formulations resulted in disintegration and wetting times of <10 seconds and <30 seconds, respectively. Tablets with drug loads from 0% to 24% epinephrine can be formulated with hardness, disintegration times, and wetting times suitable for sublingual administration.

Abstract
PURPOSE To prospectively study the impact of implementing a computed tomographic angiography (CTA)-based screening protocol on the detected incidence and associated morbidity and mortality of blunt vascular neck injury (BVNI). METHODS Consecutive blunt trauma patients admitted to a single tertiary trauma center and identified as at risk for BVNI underwent admission CTA using an eight-slice multi-detector computed tomography scanner. The detected incidence, morbidity, and mortality rates of BVNI were compared with those measured before CTA screening. A logistic regression model was also applied to further evaluate potential risk factors for BVNI. RESULTS A total of 1,313 blunt trauma patients were evaluated. One hundred seventy screening CTAs were performed, of which 33 disclosed abnormalities. Twenty-three were evaluated angiographically, of which 15 were considered to have significant BVNIs, as were 4 of the 10 patients with abnormal CTAs and no angiogram. The incidence of angiographically proven BVNIs in our series was 1.1%. If four patients who were treated for BVNIs based on CTA alone are included, the incidence rises to 1.4%. This is significantly higher than the 0.17% incidence before screening (p < 0.001). In addition, the delayed stroke rate and injury-specific mortality fell significantly from 67% to 0% (p < 0.001) and 38% to 0% (p = 0.002), respectively. Overall mortality also fell significantly, from 38% to 10.5% (p = 0.049). Univariate logistic regression identified the presence of cervical spine injury as a significant predictor of BVNI (p < 0.001). CONCLUSION CTA screening increases the detected incidence of BVNI 8-fold, with rates similar to angiographically based screening protocols. CTA screening significantly decreases BVNI-related morbidity and mortality in an efficient manner, underlying its utility in the early diagnosis of this injury.

Abstract
BACKGROUND Thoracic ultrasound (EFAST) has shown promise in inferring the presence of post-traumatic pneumothoraces (PTXs) and may have a particular value in identifying occult pneumothoraces (OPTXs) missed by the AP supine chest radiograph (CXR). However, the diagnostic utility of hand-held US has not been previously evaluated in this role. METHODS Thoracic US examinations were performed during the initial resuscitation of injured patients at a provincial trauma referral center. A high frequency linear transducer and a 2.4 kg US attached to a video-recorder were used. Real-time EFAST examinations for PTXs were blindly compared with the subsequent results of CXRs, a composite standard (CXR, chest and abdominal CT scans, clinical course, and invasive interventions), and a CT gold standard (CT only). Charts were reviewed for in-hospital outcomes and follow-up. RESULTS There were 225 eligible patients (207 blunt, 18 penetrating); 17 were excluded from the US examination because of battery failure or a lost probe. Sixty-five (65) PTXs were detected in 52 patients (22% of patients), 41 (63%) being occult to CXR in 33 patients (14.2% whole population, 24.6% of those with a CT). The US and CXR agreed in 186 (89.4%) of patients, EFAST was better in 16 (7.7%), and CXR better in 6 (2.9%). Compared with the composite standard, the sensitivity of EFAST was 58.9% with a likelihood ratio of a positive test (LR+) of 69.7 and a specificity of 99.1%. Comparing EFAST directly to CXR, by looking at each of 266 lung fields with the benefit of the CT gold standard, the EFAST showed higher sensitivity over CXR (48.8% versus 20.9%). Both exams had a very high specificity (99.6% and 98.7%), and very predictive LR+ (46.7 and 36.3). CONCLUSION EFAST has comparable specificity to CXR but is more sensitive for the detection of OPTXs after trauma. Positive EFAST findings should be addressed either clinically or with CT depending on hemodynamic stability. CT should be used if detection of all PTXs is desired.

Abstract
Reports of infectious diseases to local and state public health agencies are often delayed and incomplete. Some of the clinicians charged with the responsibility for making notifications encounter various difficulties in reporting. These may include heavy patient loads that make it easy to forget to file reports, or cumbersome disease reporting mechanisms and systems. For some percentage of practitioners, knowledge of what and when to report infectious diseases is less than optimal. However, it is not clear how reporting methods or systems could be designed or improved, owing to lack of data on physicians' knowledge and views about them. We conducted a survey of resident physicians at three university teaching hospitals in Pennsylvania to ascertain their knowledge about reporting timeframe and responsibility, as well as their attitudes toward various methods to enhance disease reporting.

Abstract
Optimal care of the injured patient requires the delivery of appropriate, definitive care shortly after injury. Over the last 30 to 40 years, civilian trauma systems and trauma centres have been developed in the United States based on experience gained in military conflicts, particularly in Korea and Vietnam. A similar process is evolving in Canada. National trauma committees in the US and Canada have defined optimal resources to meet the goal of rapid, appropriate care in trauma centres. They have introduced programs (verification or accreditation) to externally audit trauma centre performance based on these guidelines. It is generally accepted that implementing trauma systems results in decreased preventable death and improved survival after trauma. What is less clear is the degree to which each facet of trauma system development contributes to this improvement. The relative importance of national performance guidelines and trauma centre audit as integral steps toward improved outcomes following injury are reviewed. Current Trauma Association of Canada guidelines for trauma centres are presented and the process of trauma centre accreditation is discussed.

Abstract
The effectiveness of three carbohydrate sources, high-moisture ear corn (HMEC), cracked shelled corn (CSC), and a 50:50 mixture of HMEC plus dried citrus pulp (DCP), fed with or without supplemental rumen-undegraded protein as expeller soybean meal (ESBM), was assessed in 48 multiparous dairy cows. All diets contained (dry mater [DM] basis) 50% alfalfa silage, 10% ryegrass silage, 28% NDF, and one of six concentrates: A) 38% HMEC; B) 38% CSC; C) 19% DCP plus 19% HMEC; D) 27% HMEC plus 12% ESBM; E) 27% CSC plus 12% ESBM; or F) 13% DCP, 13% HMEC, and 12% ESBM. Diets A, B, and C averaged 19% crude protein, of which 53% was nonprotein nitrogen (NPN), and diets D, E, and F averaged 22% crude protein, of which 40% was NPN. Cows were fed a high-energy covariate diet for 2 wk, blocked into eight groups of six, based on covariate protein yield, then randomly assigned to diets that were fed for 12 wk. Feeding ESBM increased DM intake, yields of milk, fat-corrected milk, fat, protein, SNF, and milk and blood urea concentration and decreased weight loss. There were no production differences between HMEC and CSC. However, DM intake, yields of milk, fat-corrected milk, fat, protein, lactose, SNF, and milk SNF content all were lower on the diets containing DCP versus HMEC and CSC. A 6 x 6 Latin square trial conducted at the same time with six ruminally cannulated cows showed similar effects of diet on DM intake and milk production. Ruminal ammonia was elevated by ESBM but not ruminal total amino acids and branched-chain volatile fatty acids. Ruminal propionate was highest on HMEC diets and lowest on DCP diets; acetate, butyrate and acetate-to-propionate ratio were lowest on HMEC diets and highest on DCP diets. These results indicated that, compared to HMEC and CSC, feeding the pectin-rich carbohydrate source DCP altered ruminal fermentation but depressed intake and milk production in lactating cows.

Abstract
BACKGROUND Improved survival after injury has been demonstrated with trauma system implementation and designation of trauma centers. Local designating health authorities or national verification (United States) or accreditation (Canada) programs audit trauma center performance. The relative importance of designation versus accreditation with respect to improved outcomes is not clear. The purpose of this study was to measure outcomes within a single regional trauma system after designation of trauma centers and to compare outcomes in the one accredited center to the nonaccredited centers. METHODS Data from three trauma centers were studied. All were large, university-affiliated regional medical centers, integrated into a regional trauma system and served by a single ambulance service. The study period was 1992 to 1999, immediately after trauma center designation in 1991. The British Columbia Trauma Registry was used to identify trauma patients, mechanism of injury, length of stay, case mix, case volume, acuity, pediatric caseload, and proportion of transfers at each center. A questionnaire was circulated to each hospital to determine the level of institutional support and programmatic development for trauma. The Trauma Registry was used to calculate z scores (TRISS methodology) for each center and TRISS-adjusted mortality odds ratios between institutions. Differences in covariables were controlled for in subgroup analysis. RESULTS Two centers (hospitals A and C) had a high trauma caseload; one (hospital B) had a small and diminishing caseload. Only one center (hospital A) developed a trauma program consistent with Canadian accreditation criteria; z scores for center A were consistently better than at hospital B or C and survival odds ratios were significant. This finding applied to the total trauma population, blunt adult trauma patients (whether or not transfers and hip fracture patients were excluded), and in the more severely injured blunt trauma subgroups. There were no differences between hospitals for the relatively small number of patients with penetrating trauma. CONCLUSION Differences between hospitals were apparent from the outset of the trauma system. However, designation as a trauma center does not appear to necessarily improve survival in large regional medical centers. Development of a trauma program and commitment to meeting national guidelines through the accreditation process does appear to be associated with improved outcome after injury.

Abstract
BACKGROUND Renal trauma is reported in 3% of trauma patients. The majority (>90%) are due to blunt mechanisms of injury. Minor renal injuries pose few management difficulties and the majority are managed expectantly. More serious injuries are potentially life threatening and have been historically managed by operative intervention with repair of the injured kidney when possible. More recently, there has been a trend towards non-operative management of all solid intra-abdominal organ injury including renal trauma. The purpose of this study was to review a 7-year experience in renal trauma at a provincial trauma centre and to define management practices along with patient and organ outcomes in severe renal injury. METHODS The BC Trauma Registry was reviewed for all admissions from January 1, 1992 to December 31, 1998 to identify patients with renal injury. Patient charts were reviewed to determine sex, age, mechanism of injury, vitals, imaging, associated injuries, and management and outcomes. Renal injuries were graded according to the American Association for the Surgery of Trauma Grading System. RESULTS During the study period 16 250 consecutive trauma cases were seen at Vancouver General Hospital. Of these cases, 227 (1.4%) patients sustained renal injuries: blunt in 93.4% and penetrating in 6.6%. Among patients with blunt renal trauma, 18.3% were grade III, IV, or V injuries. In this population, nearly 80% had associated trauma and also 80% had gross hematuria. Management was conservative in 87.5% of grade III and 77.7% of grade IV; however, 90.9% of grade V injuries went immediately to the OR. Nephrectomy rates were: 12.5% (III), 16.6% (IV), and 90.9% (V) with an overall exploration rate of 7.1% for all blunt renal trauma. Blunt renal trauma patients experienced few genitourinary complications. Overall, 3 patients of 40 with grade III, IV or V injuries died due to cardiac arrest in the emergency room. CONCLUSIONS Blunt renal trauma managed conservatively is associated with few complications in the hemodynamically stable patient. Grade V injuries still result in a nephrectomy rate of 90.9% with hemodynamic instability the indication in 100% of patients.

Abstract
Histamine is an important neurotransmitter. Old (first-generation) H1-receptor antagonists such as chlorpheniramine, diphenhydramine, or triprolidine produce histamine blockade at H1-receptors in the central nervous system (CNS) and frequently cause somnolence or other CNS adverse effects. New (second generation) H1-antagonists such as cetirizine, fexofenadine, and loratadine represent an advance in therapeutics; in manufacturers' recommended doses, they enter the CNS in smaller amounts, produce relatively little somnolence or other CNS adverse effects, and do not exacerbate the adverse CNS effects of alcohol or other CNS-active chemicals. Two H1-antagonists, astemizole and terfenadine, have been found to prolong the QTc interval and, rarely, to cause cardiac dysrhythmias after overdose or under other specific conditions. This has led to withdrawal of regulatory approval for them. An H1-antagonist absolutely free from adverse effects under all circumstances is not yet available for use.

Abstract
BACKGROUND Trauma care delivery in Canada, even in major trauma centers, usually devolves to the most involved service. For patients with multisystem injuries, this is not always optimal and aspects of care outside the domain of the primary service are apt to be overlooked. Trauma care is necessarily multidisciplinary, and to be optimal, appropriate integration of the care process and prioritization are required. The purpose of this study was to examine the impact on care in a busy provincial trauma center, after the introduction of a trauma program with a clinical trauma service, revised trauma protocols, and a dedicated trauma unit. METHODS Data were collected prospectively before and during the introduction of the program. Aspects of care studied included trauma patient volume, compliance with trauma team activation and trauma consultation protocols, delays to the operating room for hypotension or open fractures, delays in disposition to the unit, average length of stay, and mortality based on Trauma and Injury Severity Score analysis. Data are presented summarized by quarter, one before and four after the introduction of the program. Variance tracking was introduced before the last quarter. Differences between preprogram and postprogram performance were assessed by using analysis of variance (asterisks indicates p < 0.05 compared with preprogram performance). RESULTS Trauma unit average length of stay decreased from 10.15 days initially to 9.66 and 9.14* days at 6 and 12 months, reducing costs. Improved survival was demonstrated by Trauma and Injury Severity Score methodology with z score achieving significance compared with Major Trauma Outcome Study outcomes after program implementation. CONCLUSION Trauma care improvement can be achieved by a multidisciplinary team focusing on the process of care, developing a dedicated trauma service to manage the more seriously injured patients, collecting them onto a single unit, and initiating program management.

Abstract
In boom times, it is easy for managers to forget about risk. And not just financial risk, but organizational and operational risk as well. Now there's the risk exposure calculator, a new tool that will help managers determine exactly where and how much internal risk is mounting in their companies. The risk calculator is divided into three parts: The first set of "keys" alerts managers to the pressures that come from growth. Now that the company has taken off, are employees feeling increased pressure to perform? Is the company's infrastructure becoming overloaded? And are more new employees coming on board as the company rushes to fill positions? If the answer is yes to any one of those questions, then risk may be rising to dangerous levels. The second set of keys on the calculator highlights pressures that arise from corporate culture. Are too many rewards being given for entrepreneurial risk taking? Are executives becoming so resistant to bad news that no one feels comfortable alerting them to problems? And is the company's level of internal competition so high that employees see promotion as a zero-sum game? The final set of pressures, the author says, revolves around information management. When calculating these pressures, managers should ask themselves, what was the company's complexity, volume, and velocity of information a year ago? Have they risen? By how much? How much of the time am I doing the work that a computer system should be doing? High pressure on many or all of these points should set off alarm bells for managers. To control risk, managers have four levers of control at their disposal that will show them where they need to make organizational adjustments.
