Background: The knowledge gap regarding acute care resource use for patients with traumatic brain injury (TBI) impedes efforts to improve the efficiency and quality of the care of these patients. Our objective was to evaluate interhospital variation in resource use for patients with TBI, identify determinants of high resource use and assess the association between hospital resource use and clinical outcomes. Methods: We conducted a multicentre retrospective cohort study including patients aged 16 years and older admitted to the inclusive trauma system of Quebec following TBI, between 2013 and 2016. We estimated resource use using activity-based costs. Clinical outcomes included mortality, complications and unplanned hospital readmission. Interhospital variation was evaluated using intraclass correlation coefficients (ICCs) with 95% confidence intervals (CIs). Correlations between hospital resource use and clinical outcomes were evaluated using correlation coefficients on weighted, risk-adjusted estimates with 95% CIs. Results: We included 6319 patients. We observed significant interhospital variation in resource use for patients discharged alive, which was not explained by patient case mix (ICC 0.052, 95% CI 0.043 to 0.061). Adjusted mean resource use for patients discharged to long-term care was more than twice that of patients discharged home. Hospitals with higher resource use tended to have a lower incidence of mortality (r -0.347, 95% CI -0.559 to -0.087) and unplanned readmission (r -0.249, 95% CI -0.481 to 0.020) but a higher incidence of complications (r 0.491, 95% CI 0.255 to 0.666). Conclusion: Resource use for TBI varies significantly among hospitals and may be associated with differences in mortality and morbidity. Negative associations with mortality and positive associations with complications should be interpreted with caution but suggest there may be a trade-off between adverse events and survival that should be evaluated further. Contexte : Le manque de donnees sur l'utilisation des ressources en soins aigus chez les patients victimes d'un traumatisme cranien (TC) nuit aux efforts pour ameliorer l'efficience et la qualite de leurs soins. Notre objectif etait d'evaluer les variations quant a l'utilisation des ressources chez les patients victimes de traumatismes craniens entre les hdpitaux, d'identifier les determinants d'une grande utilisation des ressources et d'analyser le lien entre l'utilisation des ressources hospitalieres et les resultats cliniques. Methodes : Nous avons procede a une etude de cohorte retrospective multicentrique sur des patients ages de 16 ans et plus admis dans le systeme integre de traumatologie au Quebec apres un TC, entre 2013 et 2016. Nous avons estime l'utilisation des ressources a partir des couts bases sur les activites. Les resultats cliniques incluaient mortalite, complications et rehospitalisation non planifiee. La variation entre les hdpitaux a ete evaluee a l'aide de coefficients de correlation intra-classe (CCIC), avec des intervalles de confiance (IC) de 95 %. Les correlations entre l'utilisation des ressources hospitalieres et les resultats cliniques ont ete evaluees a l'aide de coefficients de correlation sur les estimations ponderees, ajustees en fonction du risque, avec des IC de 95 %. Resultats : Nous avons inclus 6319 patients. Nous avons observe des variations significatives entre les hdpitaux pour ce qui est de l'utilisation des ressources chez les patients ayant recu leur conge de l'hdpital et elle n'a pas pu etre expliquee par la clientele (CCIC 0,052, IC de 95 % 0,043 a 0,061). L'utilisation moyenne ajustee des ressources chez les patients transferes vers un etablissement de soins prolonges etait au-dela de 2 fois plus elevee que chez les patients ayant recu leur conge de l'hopital. Les hopitaux qui ont utilise davantage de ressources ont eu tendance a avoir une incidence moindre de mortalite (r -0,347, IC de 95 % -0,559 a -0,087) et de readmissions non planifiees (r -0,249, IC de 95 % -0,481 a 0,020), mais une incidence plus elevee de complications (r 0,491, IC de 95 % 0,255 a 0,666). Conclusion : L'utilisation des ressources pour les TC varie significativement d'un hopital a l'autre et pourrait etre associee a des differences de mortalite et de morbidite. Les associations negatives avec la mortalite et positives avec les complications devraient etre interpretees avec prudence, mais suggerent qu'il y aurait lieu d'analyser plus en profondeur le rapport entre evenements defavorables et survie., In North America, traumatic brain injury (TBI) is an important cause of mortality and disability for youth and older adults.

Rationale: Patients with diabetes represent almost 20% of all ICU admissions and might respond differently to high-dose early active mobilization. Objectives: To assess whether diabetes modified the relationship between the dose of early mobilization on clinical outcomes in the TEAM trial. Methods: All TEAM trial patients were included. The primary outcome was days alive and out of the hospital at Day 180. Secondary outcomes included 180-day mortality and long-term functional outcomes at Day 180. Logistic and median regression models were used to explore the effect of high-dose early mobilization on outcomes by diabetes status. Measurements and Main Results: All 741 patients from the original trial were included. Of these, 159 patients (21.4%) had diabetes. Patients with diabetes had fewer days alive and out of the hospital at Day 180 (124 [0–153] vs. 147 [82–164]; P = 0.013) and higher 180-day mortality (30% vs. 18%; P = 0.044). In patients receiving high-dose early mobilization, the number of days alive and out of the hospital at Day 180 was 73.0 (0.0–144.5) in patients with diabetes and 146.5 (95.8–163.0) in patients without diabetes (P value for interaction = 0.108). However, in patients with diabetes, high-dose early mobilization increased the odds of mortality at 180 days (adjusted odds ratio, 3.47; 95% confidence interval, 1.67–7.61; P value for interaction = 0.001). Conclusions: In this secondary analysis of the TEAM trial, in patients with diabetes, a high-dose early mobilization strategy did not significantly decrease the number of days alive and out of the hospital at Day 180, but it increased 180-day mortality.

Objective: Hospital‐acquired infections are a common complication for patients with moderate or severe traumatic brain injury (TBI), contributing to morbidity and mortality. As infection‐mediated immune responses can predispose towards epilepsy, we hypothesized that post‐injury hospital‐acquired infections increase the risk of post‐traumatic epilepsy (PTE). Methods: A retrospective cohort study of adults with moderate to severe TBI was conducted using data from the Victorian State Trauma Registry in Australia. Infections were identified from the International Statistical Classification of Diseases and Related Health Problems 10th Revision–Australian Modification (ICD‐10‐AM) codes, and diagnosis of PTE was determined by the Glasgow Outcome Scale – Extended questionnaire regarding epileptic fits at 24 months follow‐up. Results: Of all TBI patients (n = 15 152), 24% had evidence of having had any type of infection, with the most common being pneumonia, urinary tract, and respiratory infections. Of those who responded to the PTE question at 24 months (n = 1361), 11% had developed PTE. Univariable analysis found that the incidence of PTE was higher in patients who had any type of infection compared to patients without an infection (p < 0.001). After adjustment for covariates associated with both development of PTE and risk of infection, multivariable analysis found a solid association between infection and PTE (adjusted RR = 1.59; 95% CI: 1.11–2.28; p = 0.011). Having any type of complicating infection acquired during admission was also associated with poor GOSE outcomes at subsequent follow‐ups (adjusted OR = 0.20; 95% CI: 0.11–0.35, p < 0.001). Significance: These findings suggest that hospital‐acquired infections contribute to PTE development after TBI. Future investigation into infections as a modifiable target to reduce poor outcomes after TBI is warranted. Plain Language Summary: Hospital‐acquired infections are common in patients with traumatic brain injuries. A database study of adults with moderate or severe brain injuries in Australia examined whether these infections are associated with the development of epilepsy after a brain injury. 24% of patients had infections, with pneumonia and urinary tract infections being the most common. Of those surveyed 2 years after the injury, 11% developed post‐traumatic epilepsy. Patients with infections had a significantly higher risk of epilepsy, even when accounting for other known risk factors, and infections were also linked to poor outcomes more broadly. The study suggests that preventing hospital‐acquired infections could be a crucial target for improving outcomes after traumatic brain injuries. [ABSTRACT FROM AUTHOR]

To examine feasibility and acceptability of providing stepped collaborative care case management targeting posttraumatic stress disorder (PTSD) and pain symptoms after major traumatic injury. Participants were major trauma survivors in Victoria, Australia, at risk of persistent pain or PTSD with high baseline symptoms. Participants were block-randomized, stratified by compensation-status, to the usual care (n = 15) or intervention (n = 17) group (46% of eligible patients). The intervention was adapted from existing stepped collaborative care interventions with input from interdisciplinary experts and people with lived experience in trauma and disability. The proactive case management intervention targeted PTSD and pain management for 6-months using motivational interviewing, cognitive behavioral therapy strategies, and collaborative care. Qualitative interviews explored intervention acceptability. Intervention participants received a median of 7 h case manager contact and reported that they valued the supportive and non-judgmental listening, and timely access to effective strategies, resources, and treatments post-injury from the case manager. Participants reported few disadvantages from participation, and positive impacts on symptoms and recovery outcomes consistent with the reduction in PTSD and pain symptoms measured at 1-, 3- and 6-months. Stepped collaborative care was low-cost, feasible, and acceptable to people at risk of PTSD or pain after major trauma. After hospitalization for injury, people can experience difficulty accessing timely support to manage posttraumatic stress, pain and other concerns. Stepped case management-based interventions that provide individualized support and collaborative care have reduced posttraumatic stress symptom severity for patients admitted to American trauma centers. We showed that this model of care could be adapted to target pain and mental health in the trauma system in Victoria, Australia. The intervention was low cost, acceptable and highly valued by most participants who perceived that it helped them use strategies to better manage post-traumatic symptoms, and to access clinicians and treatments relevant to their needs.

OBJECTIVE: To estimate the relative risk (RR) and excess hospitalization rate for injury in individuals with diabetes compared with the general population. RESEARCH DESIGN AND METHODS: Data were obtained from the Australian National Diabetes Services Scheme, hospitalization data sets, the Australian Pharmaceutical Benefits Scheme, the National Death Index, and the census spanning from 2011 to 2017. Hospitalizations for injury were coded as head and neck, lower-extremity, upper-extremity, or abdominal and thoracic injury; burns; or other injury. Poisson regression was used to estimate the age- and sex-adjusted RR of hospitalization for injury. RESULTS: The total number of hospitalizations for any injury was 117,705 in people with diabetes and 3,463,173 in the general population. Compared with that in the general population, an elevated adjusted risk of admission was observed for any injury (RR 1.22; 95% CI 1.21, 1.22), head and neck (1.28; 1.26, 1.30), lower extremity (1.24; 1.23, 1.26), abdominal and thoracic (1.29; 1.27, 1.30), upper extremity (1.03; 1.02, 1.05), burns (1.52; 1.44, 1.61), and other injury (1.37; 1.33, 1.40). The adjusted RR of any injury was 1.62 (1.58, 1.66) in individuals with type 1 diabetes, 1.65 (1.63, 1.66) in those with type 2 diabetes who were taking insulin, and 1.07 (1.06, 1.08) in individuals with type 2 diabetes not using insulin. Falls were the primary cause of injury in individuals with diabetes. CONCLUSIONS: Individuals with diabetes, especially those using insulin, had a higher risk of hospitalization for injury compared with the general population. [ABSTRACT FROM AUTHOR]

Issue: Hospital alcohol and/or other drug (AOD) testing is important for identifying AOD‐related injuries; however, testing methods vary. This systematic review aimed to examine biological AOD testing methods from hospital‐based studies of injured patients and quantify what proportion reported key information on those testing methods. Approach: Observational studies published in English from 2010 onwards involving biological AOD testing for injured patients presenting to hospital were included. Studies examining single injury causes were excluded. Extracted data included concentration thresholds for AOD detection (e.g., lower limits of detection, author‐defined cut‐offs), test type (e.g., immunoassay, breathalyser) and approach (e.g., routine, clinical discretion), timing of testing, sample type and the proportion of injured cases tested for AODs. Key Findings: Of 83 included studies, 76 measured alcohol and 37 other drugs. Forty‐nine studies defined blood alcohol concentration thresholds (ranging from 0 to 0.1 g/100 mL). Seven studies defined concentration thresholds for other drugs. Testing approach was reported in 39/76 alcohol and 18/37 other drug studies. Sample type was commonly reported (alcohol: n = 69/76; other drugs: n = 28/37); alcohol was typically measured using blood (n = 60) and other drugs using urine (n = 20). Studies that reported the proportion of cases tested (alcohol: n = 53/76; other drugs: n = 28/37), reported that between 0% and 89% of cases were not tested for alcohol and 0% and 91% for other drugs. Timing of testing was often unreported (alcohol: n = 61; other drugs: n = 30). Implications and Conclusion: Variation in AOD testing methods alongside incomplete reporting of those methods limits data comparability and interpretation. Standardised reporting of testing methods will assist AOD‐related injury surveillance and prevention. [ABSTRACT FROM AUTHOR]

Objective: To measure the prevalence of alcohol and/or other drug (AOD) detections in suspected major trauma patients with non‐transport injuries who presented to an adult major trauma centre. Methods: This registry‐based cohort study examined the prevalence of AOD detections in patients aged ≥18 years who: (i) sustained non‐transport injuries; and (ii) met predefined trauma call‐out criteria and were therefore managed by an interdisciplinary trauma team between 1 July 2021 and 31 December 2022. Prevalence was measured using routine in‐hospital blood alcohol and urine drug screens. Results: A total of 1469 cases met the inclusion criteria. Of cases with a valid blood test (n = 1248, 85.0%), alcohol was detected in 313 (25.1%) patients. Of the 733 (49.9%) cases with urine drug screen results, cannabinoids were most commonly detected (n = 103, 14.1%), followed by benzodiazepines (n = 98, 13.4%), amphetamine‐type substances (n = 80, 10.9%), opioids (n = 28, 3.8%) and cocaine (n = 17, 2.3%). Alcohol and/or at least one other drug was detected in 37.4% (n = 472) of cases with either a blood alcohol or urine drug test completed (n = 1263, 86.0%). Multiple substances were detected in 16.6% (n = 119) of cases with both blood alcohol and urine drug screens (n = 718, 48.9%). Detections were prevalent in cases of interpersonal violence (n = 123/179, 68.7%) and intentional self‐harm (n = 50/106, 47.2%), and in those occurring on Friday and Saturday nights (n = 118/191, 61.8%). Conclusion: AOD detections were common in trauma patients with non‐transport injury causes. Population‐level surveillance is needed to inform prevention strategies that address AOD use as a significant risk factor for serious injury. [ABSTRACT FROM AUTHOR]

Substance use is a risk factor for being both a perpetrator and a victim of violence. The aim of this systematic review was to report the prevalence of acute pre-injury substance use in patients with violence-related injuries. Systematic searches were used to identify observational studies that included patients aged ≥15 years presenting to hospital after violence-related injuries and used objective toxicology measures to report prevalence of acute pre-injury substance use. Studies were grouped based on injury cause (any violence-related, assault, firearm, and other penetrating injuries including stab and incised wounds) and substance type (any substance, alcohol only, drugs other than alcohol only), and they were summarized using narrative synthesis and meta-analyses. This review included 28 studies. Alcohol was detected in 13%–66% of any violence-related injuries (five studies), 4%–71% of assaults (13 studies), 21%–45% of firearm injuries (six studies; pooled estimate = 41%, 95% CI: 40%–42%, n = 9,190), and 9%–66% of other penetrating injuries (nine studies; pooled estimate = 60%, 95% CI: 56%–64%, n = 6,950). Drugs other than alcohol were detected in 37% of any violence-related injuries (one study), 39% of firearm injuries (one study), 7%–49% of assaults (five studies), and 5%–66% of penetrating injuries (three studies). The prevalence of any substance varied across injury categories: any violence-related injuries = 76%–77% (three studies), assaults = 40%–73% (six studies), firearms = n/a, other penetrating injuries = 26%–45% (four studies; pooled estimate = 30%, 95% CI: 24%–37%, n = 319).Overall, substance use was frequently detected in patients presenting to hospital for violence-related injuries. Quantification of substance use in violence-related injuries provides a benchmark for harm reduction and injury prevention strategies. [ABSTRACT FROM AUTHOR]
