Exploring the usability of simulated patient methodology in dental clinics in Western Australia: A pilot survey.

OBJECTIVES: This study aimed to explore the dental staff knowledge of simulated patient methodology and support for its use to investigate dental staffs' triaging ability. MATERIAL AND METHODS: Staff at dental practices in Western Australia were invited to participate in a cross-sectional online questionnaire, consisting of demographic questions, questions on triaging, and knowledge of simulated patient methodology. Descriptive and parametric tests were undertaken for quantitative data; qualitative responses were thematically analyzed. RESULTS: Of the 100 participants, most were female (71%), aged 25-39 years (57%), dentists (46%), and worked in private practices (60%). While 82% of participants triaged dental appointment enquiries, only 26% had heard of simulated patient studies. The majority (66%) of participants spent 1-5 min when triaging appointments and less than half (29%) asked about medical history, aggravating or alleviating factors. Although there was a general positive attitude toward use of simulated patient methodology to investigate practice, some concerns were identified. CONCLUSIONS: The findings of our exploratory study suggests that there may be a potential for utilizing simulated patient studies to improve the care of patients by dental receptionists in general dental practices.

Canadian nurse initiated analgesia protocol to reduce delays in the emergency department: A quality improvement study.

BACKGROUND: Australian literature supports nurse-initiated opioid analgesia protocols may be effective, but this practice is not yet widely adopted in Canada. LOCAL PROBLEM: Previous quality audits of Emergency Departments (EDs) in Victoria (Canada) indicate long delays to administration of analgesia. METHODS: Two tertiary care hospitals in a Canadian city of approximately 400,000 people were chosen for a quality improvement initiative. A manual retrospective chart review was conducted on a total of 122 patients which was compared to data from 125 patients from a previous audit in 2019. INTERVENTIONS: ED nursing staff both hospitals were provided education and daily reminders to document pain score at triage, and to flag an acute analgesia opioid order set on the charts of patients with moderate or severe pain (greater than 4 out of 10 in the Numerical Rating Scale (NRS) or by triage nurse's clinical judgment). At Victoria General Hospital (VGH), nurses had the option of finding an emergency physician (EP) to sign the acute analgesia opioid order set, or independently administer IV opioids from a presigned order set without consulting an EP. At Royal Jubilee Hospital (RJH), nursing staff could only administer IV opioids from the order set after an EP was consulted. Median time to opioid analgesia after the intervention was compared to 2019 data for each hospital. RESULTS: Each hospital significantly reduced median time to administration of opioids: VGH achieved 45.6 % reduction (1 h 8 min improvement, p = 0.001) and RJH achieved a 62.5 % reduction (2 h 11 min improvement, p < 0.001). Secondary outcomes indicated patients may receive analgesia faster when the opioid protocol was nurse initiated (median 43 minutes) vs physician initiated (median 1 h 1 min) at VGH. Pain score documentation at triage improved from <10 % in 2019 to >50 % in 2020 at both sites. Approximately 95 % of EP and nursing staff thought nurse-initiated opioids are safe, effective, and should be supported by regulatory boards. CONCLUSION: Implementing a new triage protocol to expedite initiation of an analgesic protocol was associated with significantly reduced time to analgesia for patients with moderate to severe pain. Time reductions may be greater with nurse-initiated analgesia before physician assessment.

Validation of the Korean Version of the Clinical Frailty Scale-Adjusted Korean Triage and Acuity Scale for Older Patients in the Emergency Department.

Background and Objectives: The Clinical Frailty Scale (CFS), used to screen for prehospital frailty in patients aged >65 years, is simple, time-efficient, and has been validated in emergency departments (EDs). In this study, we analyzed whether the Korean Triage and Acuity Scale (KTAS) classification by level in older patients determined to have frailty based on the Korean version of the CFS increases the triage performance of the current KTAS. Materials and Methods: The primary outcome was 30-day in-hospital mortality, and secondary outcomes were hospital and intensive care unit (ICU) admissions. This study retrospectively analyzed prospectively collected data from three ED centers. Patients with a CFS score ranging from five (mildly frail) to nine (terminally ill) were categorized into the frailty group. We upgraded the KTAS classification of the frailty group by one level of urgency and defined this as the CFS-KTAS. Results: The cutoff values for predicting admission were three and two for the KTAS and CFS-KTAS, respectively. A significant difference was observed in the area under the receiver operating characteristic (AUROC) curve between the KTAS and CFS-KTAS. To predict ICU admission, the cutoff score was two for both scales. A significant difference was observed in the AUROC curve between the KTAS and CFS-KTAS. For predicting in-hospital mortality, the cutoff score was two for both scales. A significant difference was observed in the AUROC curve between the KTAS and CFS-KTAS. Conclusions: This study showed that the CFS-adjusted KTAS has a more useful prognostic value than the KTAS alone for predicting hospital outcomes in older patients.

Triage Performance Across Large Language Models, ChatGPT, and Untrained Doctors in Emergency Medicine: Comparative Study.

BACKGROUND: Large language models (LLMs) have demonstrated impressive performances in various medical domains, prompting an exploration of their potential utility within the high-demand setting of emergency department (ED) triage. This study evaluated the triage proficiency of different LLMs and ChatGPT, an LLM-based chatbot, compared to professionally trained ED staff and untrained personnel. We further explored whether LLM responses could guide untrained staff in effective triage. OBJECTIVE: This study aimed to assess the efficacy of LLMs and the associated product ChatGPT in ED triage compared to personnel of varying training status and to investigate if the models' responses can enhance the triage proficiency of untrained personnel. METHODS: A total of 124 anonymized case vignettes were triaged by untrained doctors; different versions of currently available LLMs; ChatGPT; and professionally trained raters, who subsequently agreed on a consensus set according to the Manchester Triage System (MTS). The prototypical vignettes were adapted from cases at a tertiary ED in Germany. The main outcome was the level of agreement between raters' MTS level assignments, measured via quadratic-weighted Cohen κ. The extent of over- and undertriage was also determined. Notably, instances of ChatGPT were prompted using zero-shot approaches without extensive background information on the MTS. The tested LLMs included raw GPT-4, Llama 3 70B, Gemini 1.5, and Mixtral 8x7b. RESULTS: GPT-4-based ChatGPT and untrained doctors showed substantial agreement with the consensus triage of professional raters (κ=mean 0.67, SD 0.037 and κ=mean 0.68, SD 0.056, respectively), significantly exceeding the performance of GPT-3.5-based ChatGPT (κ=mean 0.54, SD 0.024; P<.001). When untrained doctors used this LLM for second-opinion triage, there was a slight but statistically insignificant performance increase (κ=mean 0.70, SD 0.047; P=.97). Other tested LLMs performed similar to or worse than GPT-4-based ChatGPT or showed odd triaging behavior with the used parameters. LLMs and ChatGPT models tended toward overtriage, whereas untrained doctors undertriaged. CONCLUSIONS: While LLMs and the LLM-based product ChatGPT do not yet match professionally trained raters, their best models' triage proficiency equals that of untrained ED doctors. In its current form, LLMs or ChatGPT thus did not demonstrate gold-standard performance in ED triage and, in the setting of this study, failed to significantly improve untrained doctors' triage when used as decision support. Notable performance enhancements in newer LLM versions over older ones hint at future improvements with further technological development and specific training.

Enhancing triage accuracy: The influence of nursing education on risk prediction.

AIM: This study aimed to compare the performance in risk prediction of various outcomes between specially trained triage nurses and the Manchester Triage System (MTS). DESIGN: Prospective observational study. METHODS: The study was conducted from June 1st to December 31st, 2023, at the Emergency Department of Merano Hospital. Triage nurses underwent continuous training through dedicated courses and daily audits. We compared the risk stratification performed by expert nurses with that of MTS on various outcomes such as mortality, hospitalisation, and urgency defined by the physicians. Comparisons were made using the Areas Under the Receiver Operating Characteristic curve (AUROC). RESULTS: The agreement in code classification between the MTS and the expert nurse was very low. The AUROC curve analysis showed that the expert nurse outperformed the MTS in all outcomes. The triage nurse's experience led to statistically significant better stratification in admission rates, ICU admissions, and all outcomes based on the physician's assessment. CONCLUSIONS: The continuous training of nurses enables them to achieve better risk prediction compared to standardized triage systems like MTS, emphasizing the utility and necessity of implementing continuous training pathways for these highly specialised personnel.

Use of Mobile Technologies to Streamline Pretriage Patient Flow in the Emergency Department: Observational Usability Study.

BACKGROUND: In emergency departments (EDs), triage nurses are under tremendous daily pressure to rapidly assess the acuity level of patients and log the collected information into computers. With self-service technologies, patients could complete data entry on their own, allowing nurses to focus on higher-order tasks. Kiosks are a popular working example of such self-service technologies; however, placing a sufficient number of unwieldy and fixed machines demands a spatial change in the greeting area and affects pretriage flow. Mobile technologies could offer a solution to these issues. OBJECTIVE: The aim of this study was to investigate the use of mobile technologies to improve pretriage flow in EDs. METHODS: The proposed stack of mobile technologies includes patient-carried smartphones and QR technology. The web address of the self-registration app is encoded into a QR code, which was posted directly outside the walk-in entrance to be seen by every ambulatory arrival. Registration is initiated immediately after patients or their proxies scan the code using their smartphones. Patients could complete data entry at any site on the way to the triage area. Upon completion, the result is saved locally on smartphones. At the triage area, the result is automatically decoded by a portable code reader and then loaded into the triage computer. This system was implemented in three busy metropolitan EDs in Shanghai, China. Both kiosks and smartphones were evaluated randomly while being used to direct pretriage patient flow. Data were collected during a 20-day period in each center. Timeliness and usability of medical students simulating ED arrivals were assessed with the After-Scenario Questionnaire. Usability was assessed by triage nurses with the Net Promoter Score (NPS). Observations made during system implementation were subject to qualitative thematic analysis. RESULTS: Overall, 5928 of 8575 patients performed self-registration on kiosks, and 7330 of 8532 patients checked in on their smartphones. Referring effort was significantly reduced (43.7% vs 8.8%; P<.001) and mean pretriage waiting times were significantly reduced (4.4, SD 1.7 vs 2.9, SD 1.0 minutes; P<.001) with the use of smartphones compared to kiosks. There was a significant difference in mean usability scores for "ease of task completion" (4.4, SD 1.5 vs 6.7, SD 0.7; P<.001), "satisfaction with completion time" (4.5, SD 1.4 vs 6.8, SD 0.6; P<.001), and "satisfaction with support" (4.9, SD 1.9 vs 6.6, SD 1.2; P<.001). Triage nurses provided a higher NPS after implementation of mobile self-registration compared to the use of kiosks (13.3% vs 93.3%; P<.001). A modified queueing model was identified and qualitative findings were grouped by sequential steps. CONCLUSIONS: This study suggests patient-carried smartphones as a useful tool for ED self-registration. With increased usability and a tailored queueing model, the proposed system is expected to minimize pretriage waiting for patients in the ED.

[Phone triage in primary care practices]. / Triage téléphonique en cabinet de médecine de famille.

In primary care medicine for adult or pediatric populations, phone calls from patients or parents are common. The variety of questions is broad, going from simple administrative requests to life-threatening emergencies. The safety of the patient is the main priority when answering these calls. In opposition to emergency departments in hospitals where numerous well-defined triage systems (for example, Swiss Emergency Triage Scale), including clinical exam with vital signs, have been used, it is difficult to find practical guidelines for a safe and efficient phone triage in medical practices. Swiss pediatricians already use a triage book to help them assess the need for emergency care for their young patients. A similar type of resource would be helpful for a safe management of calls in adult medicine.

En cabinet de médecine de famille, adulte ou pédiatrique, les appels téléphoniques de patients ou de leurs proches sont nombreux. Leurs questions sont variées, allant de la simple requête administrative à l'urgence vitale. La sécurité du patient reste la priorité principale dans les réponses apportées lors de ces appels. Contrairement aux systèmes d'urgences hospitalières utilisant de multiples échelles de tri comprenant un examen clinique de base avec signes vitaux (par exemple, Échelle suisse de tri), il existe peu de stratégies pour un triage efficace et sûr en médecine de cabinet. Les pédiatres suisses utilisent actuellement un guide au triage téléphonique visant à cibler correctement les besoins urgents de soins pour leurs jeunes patients. Un équivalent pour la médecine adulte serait une aide supplémentaire pour une prise en charge en toute sécurité.

Quality improvement initiative: improving obstetric triaging practices in a rural maternal hospital in central India.

Triaging of obstetric patients by emergency care providers is paramount. It helps provide appropriate and timely management to prevent further injury and complications. Standardised trauma acuity scales have limited applicability in obstetric triage. Specific obstetric triage index tools improve maternal and neonatal outcomes but remain underused. The aim was to introduce a validity-tested obstetric triage tool to improve the percentage of correctly triaged patients (correctly colour-coded in accordance with triage index tool and attended to within the stipulated time interval mandated by the tool) from the baseline of 49% to more than 90% through a quality improvement (QI) process.A team of nurses, obstetricians and postgraduates did a root cause analysis to identify the possible reasons for incorrect triaging of obstetric patients using process flow mapping and fish bone analysis. Various change ideas were tested through sequential Plan-Do-Study-Act (PDSA) cycles to address issues identified.The interventions included introduction and application of an obstetric triage index tool, training of triage nurses and residents. We implemented these interventions in eight PDSA cycles and observed outcomes by using run charts. A set of process, output and outcome indicators were used to track if changes made were leading to improvement.Proportion of correctly triaged women increased from the baseline of 49% to more than 95% over a period of 8 months from February to September 2020, and the results have been sustained in the last PDSA cycle, and the triage system is still sustained with similar results. The median triage waiting time reduced from the baseline of 40 min to less than 10 min. There was reduction in complications attributable to improper triaging such as preterm delivery, prolonged intensive care unit stay and overall morbidity. It can be thus concluded that a QI approach improved obstetric triaging in a rural maternity hospital in India.

Field trauma triage criteria associated with need for dedicated trauma center care: a single-center retrospective cohort study.

INTRODUCTION: Direct transport from the scene of injury to a trauma centre reduces saves lives. In Ontario, paramedics use the field trauma triage standard (FTTS) to determine if a patient meets trauma bypass criteria. Recent studies have questioned the efficacy of the FTTS in identifying severely injured patients. The objective of this study was to determine the predictive performance of the FTTS on the need for trauma center care in patients who were transported to a trauma center. METHODS: This was a single-center health records study of patients transported by ambulance directly to a level 1 trauma center. Hospital based trauma center need and injury severity score-based need were defined. Bivariate associations with one or more FTTS criteria were tested using the Wilcoxon two-sample test for continuous variables, and the Chi-square or Fisher's exact test for categorical indicators. The sensitivity and specificity of each category of the FTTS were calculated. RESULTS: There were 1427 patients included in the study, with 76% men, mean age of 40, and 76% had a blunt mechanism. The overall sensitivity and specificity of the FTTS was 90.9% and 20.8% for hospital-based need and 91.6% and 20.3 for injury severity need. The most sensitive variable for hospital-based need was physiologic criteria (53.7). Mechanism of injury was the most sensitive criteria for injury severity need (54.8). Physiological criteria had the highest association with hospital-based and injury severity need (adjusted odds ratios 7.5 [95% CI 5.8-9.8] and 5.1 [95% CI 3.9-6.7]). CONCLUSIONS: The FTTS has fair performance in identifying the need for hospital-based and injury severity need. Systolic blood pressure less than 90 mmHg, Glasgow Coma Scale (motor) less than 6, and falls greater than 6 m were most predictive of trauma center need. Improving prehospital trauma triage is critical to ensure timely transport to a trauma centre.

RéSUMé: INTRODUCTION: Le transport direct de la scène de la blessure à un centre de traumatologie permet de sauver des vies. En Ontario, les ambulanciers paramédicaux utilisent la norme de triage des traumatismes sur le terrain (FTTS) pour déterminer si un patient répond aux critères de pontage traumatique. Des études récentes ont remis en question l'efficacité du FTTS dans l'identification des patients gravement blessés. L'objectif de cette étude était de déterminer la performance prédictive du FTTS sur le besoin de soins en centre de traumatologie chez les patients qui ont été transportés dans un centre de traumatologie. MéTHODES: Il s'agissait d'une étude des dossiers médicaux d'un seul centre portant sur des patients transportés par ambulance directement à un centre de traumatologie de niveau 1. Les besoins des centres de traumatologie hospitaliers et les besoins basés sur le score de gravité des blessures ont été définis. Les associations bivariées avec un ou plusieurs critères FTTS ont été testées à l'aide du test à deux échantillons de Wilcoxon pour les variables continues et du test de Fisher pour les indicateurs catégoriels. La sensibilité et la spécificité de chaque catégorie du FTTS ont été calculées. RéSULTATS: Il y avait 1427 patients inclus dans l'étude, avec 76% d'hommes, âge moyen de 40, et 76% avaient un mécanisme émoussé. La sensibilité et la spécificité globales du FTTS étaient de 90,9 % et de 20,8 % pour les besoins hospitaliers et de 91,6 % et de 20,3 % pour les besoins de gravité des blessures. La variable la plus sensible pour les besoins hospitaliers était les critères physiologiques (53,7). Le mécanisme de blessure était le critère le plus sensible pour le besoin de gravité de la blessure (54,8). Les critères physiologiques étaient les plus associés aux besoins hospitaliers et aux besoins en matière de gravité des blessures (rapports de cotes ajustés de 7,5 [IC à 95 % 5,8-9,8] et 5,1 [IC à 95 % 3,9-6,7]). CONCLUSION: Le FTTS a un rendement équitable pour ce qui est de déterminer le besoin de soins hospitaliers et de gravité des blessures. La pression artérielle systolique inférieure à 90mmHg, l'échelle de coma de Glasgow (moteur) inférieure à 6 et les chutes supérieures à 6m étaient les plus prédictives des besoins du centre de traumatologie. L'amélioration du triage des traumatismes avant l'hospitalisation est essentielle pour assurer un transport rapide vers un centre de traumatologie.

Midwife-led obstetric triage to increase providers' knowledge and improve timeliness of care: A pre and posttest design.

BACKGROUND: Research in low- and middle-income countries has shown that maternal mortality is directly related to inadequate or absent obstetric (OB) triage systems. Standard triage systems and knowledge on triaging for obstetric emergencies are often absent or lacking in most healthcare systems in Liberia. OBJECTIVE: The objective of this research was to address the third delay defined as receiving adequate, quality care when a facility is reached by increasing knowledge through the establishment of a midwife-led, hospital-based OB triage system to stratify care based on risk and imminence of birth and to improve timely assessment at two district referral hospitals. METHODS: A quasi-experimental study design using a pre/post survey was employed for a midwife-led OB triage training course. Using a train-the-trainer model, five midwives were trained as champions, who in turn trained an additional 62 providers. Test results were analyzed with the R statistical software using paired sample t-test and descriptive statistics. RESULTS: Pretest results revealed a knowledge and practice gap among OB providers on key components of the standard triage package. However, post-test mean scores were significantly higher (M = 79.6, SD = 2.32) than pre-test mean scores (M = 59.0, SD = 2.30) for participants following a 2-day training (p = <0.001). DISCUSSION: Following a structured OB triage training, participants showed significant improvement in post-test OB triage scores. CONCLUSION: Standard OB triage protocols incorporated into the policies and procedures of obstetric wards have the potential to improve knowledge and practice, addressing the third delay and reducing preventable, obstetrics-related deaths.

Use of Reverse Shock Index Multiplied by Simplified Motor Score in a Five-Level Triage System: Identifying Trauma in Adult Patients at a High Risk of Mortality.

Background and Objectives: The Taiwan Triage and Acuity Scale (TTAS) is reliable for triaging patients in emergency departments in Taiwan; however, most triage decisions are still based on chief complaints. The reverse-shock index (SI) multiplied by the simplified motor score (rSI-sMS) is a more comprehensive approach to triage that combines the SI and a modified consciousness assessment. We investigated the combination of the TTAS and rSI-sMS for triage compared with either parameter alone as well as the SI and modified SI. Materials and Methods: We analyzed 13,144 patients with trauma from the Taipei Tzu Chi Trauma Database. We investigated the prioritization performance of the TTAS, rSI-sMS, and their combination. A subgroup analysis was performed to evaluate the trends in all clinical outcomes for different rSI-sMS values. The sensitivity and specificity of rSI-sMS were investigated at a cutoff value of 4 (based on previous study and the highest score of the Youden Index) in predicting injury severity clinical outcomes under the TTAS system were also investigated. Results: Compared with patients in triage level III, those in triage levels I and II had higher odds ratios for major injury (as indicated by revised trauma score < 7 and injury severity score [ISS] ≥ 16), intensive care unit (ICU) admission, prolonged ICU stay (≥14 days), prolonged hospital stay (≥30 days), and mortality. In all three triage levels, the rSI-sMS < 4 group had severe injury and worse outcomes than the rSI-sMS ≥ 4 group. The TTAS and rSI-sMS had higher area under the receiver operating characteristic curves (AUROCs) for mortality, ICU admission, prolonged ICU stay, and prolonged hospital stay than the SI and modified SI. The combination of the TTAS and rSI-sMS had the highest AUROC for all clinical outcomes. The prediction performance of rSI-sMS < 4 for major injury (ISS ≥ 16) exhibited 81.49% specificity in triage levels I and II and 87.6% specificity in triage level III. The specificity for mortality was 79.2% in triage levels I and II and 87.4% in triage level III. Conclusions: The combination of rSI-sMS and the TTAS yielded superior prioritization performance to TTAS alone. The integration of rSI-sMS and TTAS effectively enhances the efficiency and accuracy of identifying trauma patients at a high risk of mortality.

Defining Mild Traumatic Brain Injury: From Research Definition to Clinical Practice.

INTRODUCTION: Approximately 75% of traumatic brain injuries (TBIs) qualify as mild. However, there exists no universally agreed upon definition for mild TBI (mTBI). Consequently, treatment guidelines for this group are lacking. The Center for Disease Control (CDC), American College of Rehabilitation Medicine (ACRM), Veterans Affairs and Department of Defense (VA/DoD), Eastern Association for the Surgery of Trauma (EAST), and the University of Arizona's Brain Injury Guidelines (BIG) have each published differing definitions for mTBI. The aim of this study was to compare the ability of these definitions to correctly classify mTBI patients in the acute care setting. METHODS: A single-center, retrospective cohort study comparing the performance of the varying definitions of mTBI was performed at a Level I trauma center from August 2015 to December 2018. Definitions were compared by sensitivity, specificity, positive predictive value, negative predictive value, as well as overtriage and undertriage rates. Finally, a cost-savings analysis was performed. RESULTS: We identified 596 patients suffering blunt TBI with Glasgow Coma Scale 13-15. The CDC/ACRM definitions demonstrated 100% sensitivity but 0% specificity along with the highest rate of undertriage and TBI-related mortality. BIG 1 included nearly twice as many patients than EAST and VA/DoD while achieving a superior positive predictive value and undertriage rate. CONCLUSIONS: The BIG definition identified a larger number of patients compared to the VA/DoD and EAST definitions while having an acceptable and more accurate overtriage and undertriage rate compared to the CDC and ACRM. By eliminating undertriage and minimizing overtriage rates, the BIG maintains patient safety while enhancing the efficiency of healthcare systems. Using the BIG definition, a cost savings of $395,288.95-$401,263.95 per year could be obtained at our level 1 trauma facility without additional mortality.

Optimizing Triage Practice in Pediatric Trauma: Lessons From Under-triage and Over-triage Rates and Risk Factors.

BACKGROUND: Triage accuracy is essential for delivering effective trauma care, especially in the pediatric population where unique challenges exist. The purpose of this study was to investigate risk factors contributing to under-triage and over-triage in an urban pediatric trauma center. METHODS: This retrospective cohort study included all trauma activations at an urban level 1 trauma center between January 1, 2021, and July 31, 2023 (patients <18 years old.) Patients who were under- or over-triaged were identified based on the level of trauma activation and injury severity score. RESULTS: There were 1094 trauma activations included in this study. The rate of under-triage was 3.8% (n = 42) and over-triage was 13.6% (n = 149). Infants aged 0-1 years had the highest rate of under-triage (10.9%, n = 19, P < .001), while those aged 11-17 had the highest rate of over-triage (17.0%, n = 82, P = .003). Non-accidental trauma was the strongest risk factor for under-triage (OR 30.2 [6.4-142.8] P < .001). Penetrating mechanism was the strongest risk factor for over-triage (OR 12.2 [5.6-26.2] P < .001). DISCUSSION: This study reveals the complexity of trauma triage in the pediatric population. We identified key predictive factors, such as age, comorbidities, and mechanism of injury, that can be used to refine triage practices and improve the care of pediatric trauma patients.

Predictive value and interrater reliability of mental status and mobility assessment in the emergency department.

AIM: To investigate the predictive value of both mental status, assessed with the AVPUC (Alert, responds to Voice, responds to Pain, Unresponsive, and new Confusion) scale, and mobility assessments, and their interrater reliability (IRR) between triage clinicians and a research team. METHOD: Prospective study of consecutive patients who presented to an ED. Mental status and mobility were assessed by triage clinicians and by a dedicated research team. RESULTS: 4,191 patients were included. After adjustment for age and sex, patients with altered mental status have an odds ratio of 6.55 [4.09-10.24] to be admitted in the ICU and an odds ratio of 21.16 [12.06-37.01] to die within 30 days; patients with impaired mobility have an odds ratio of 7.08 [4.60-11.12] to be admitted in the ICU and an odds ratio of 12.87 [5.93-32.30] to die within 30 days. The kappa coefficient between triage clinicians and the research team for mental status assessment was 0.75, and 0.80 for mobility. CONCLUSION: Assessment of mental status by the AVPUC scale, and mobility by a simple dichotomous scale are suitable for ED triage. Both altered mental status and impaired mobility are associated with adverse outcomes. Mental status and mobility assessment have good interrater reliability.

In Search of the Truth: Choice of Ground Truth for Predictive Modeling of Trauma Team Activation in Pediatric Trauma.

BACKGROUND: Assigning trauma team activation (TTA) levels for trauma patients is a classification task that machine learning models can help optimize. However, performance is dependent on the "ground-truth" labels used for training. Our purpose was to investigate 2 ground truths, the Cribari matrix and the Need for Trauma Intervention (NFTI), for labeling training data. STUDY DESIGN: Data were retrospectively collected from the institutional trauma registry and electronic medical record, including all pediatric patients (age <18 years) who triggered a TTA (January 2014 to December 2021). Three ground truths were used to label training data: (1) Cribari (Injury Severity Score >15 = full activation), (2) NFTI (positive for any of 6 criteria = full activation), and (3) the union of Cribari+NFTI (either positive = full activation). RESULTS: Of 1,366 patients triaged by trained staff, 143 (10.47%) were considered undertriaged using Cribari, 210 (15.37%) using NFTI, and 273 (19.99%) using Cribari+NFTI. NFTI and Cribari+NFTI were more sensitive to undertriage in patients with penetrating mechanisms of injury (p = 0.006), specifically stab wounds (p = 0.014), compared with Cribari, but Cribari indicated overtriage in more patients who required prehospital airway management (p < 0.001), CPR (p = 0.017), and who had mean lower Glasgow Coma Scale scores on presentation (p < 0.001). The mortality rate was higher in the Cribari overtriage group (7.14%, n = 9) compared with NFTI and Cribari+NFTI (0.00%, n = 0, p = 0.005). CONCLUSIONS: To prioritize patient safety, Cribari+NFTI appears best for training a machine learning algorithm to predict the TTA level.

An Assessment of Clinical Accuracy of Vital Sign-based Triage Tools Among U.S. and Coalition Forces.

INTRODUCTION: Early appropriate allocation of resources for critically injured combat casualties is essential. This is especially important when inundated with an overwhelming number of casualties where limited resources must be efficiently allocated, such as during mass casualty events. There are multiple scoring systems utilized in the prehospital combat setting, including the shock index (SI), modified shock index (MSI), simple triage and rapid treatment (START), revised trauma score (RTS), new trauma score (NTS), Glasgow Coma Scale + age + pressure (GAP), and the mechanism + GAP (MGAP) score. The optimal score for application to the combat trauma population remains unclear. MATERIALS AND METHODS: This is a secondary analysis of a previously described dataset from the Department of Defense Trauma Registry from January 1, 2007 through March 17, 2020. We constructed univariable analyses to determine the area under the receiving operator characteristic (AUROC) for the scoring systems of interest. Our primary outcomes were early death (within 24 hours) or early massive transfusion, as defined by ≥3 units. RESULTS: There were 12,268 casualties that met inclusion criteria. There were 168 (1%) who died within the first 24 hours and 2082 (17%) that underwent significant transfusion within the first 24 hours. When assessing the predictive capabilities for death within 24 hours, the AUROCs were 0.72 (SI), 0.69 (MSI), 0.89 (START), 0.90 (RTS), 0.83 (NTS), 0.90 (GAP), and 0.91 (MGAP). The AUROCs for massive transfusion were 0.89 (SI), 0.89 (MSI), 0.82 (START), 0.81 (RTS), 0.83 (NTS), 0.85 (MGAP), and 0.86 (GAP). CONCLUSIONS: This study retrospectively applied seven triage tools to a database of 12,268 cases from the Department of Defense Trauma Registry to evaluate their performance in predicting early death or massive transfusion in combat. All scoring systems performed well with an AUROC >0.8 for both outcomes. Although the SI and MSI performed best for predicting massive transfusion (both had an AUROC of 0.89), they ranked last for assessment of mortality within 24 hours, with the other tools performing well. START, RTS, NTS, MGAP and GAP reliably identified early death and need for massive transfusion, with MGAP and GAP performing the best overall. These findings highlight the importance of assessing triage tools to best manage resources and ultimately preserve lives of traumatically wounded warfighters. Further studies are needed to explain the surprising performance discrepancy of the SI and MSI in predicting early death and massive transfusion.

Evaluation of prehospital preparedness for major incidents on a national level, with focus on mass casualty incidents.

PURPOSE: To investigate prehospital preparedness work for Mass Casualty Incidents (MCI) and Major Incidents (MI) in Norway. METHOD: A national cross-sectional descriptive study of Norway's prehospital MI preparedness through a web-based survey. A representative selection of Rescue and Emergency Services were included, excluding Non-Governmental Organisations and military. The survey consisted of 59 questions focused on organisation, planning, education/training, exercises and evaluation. RESULTS: Totally, 151/157 (96%) respondents answered the survey. The results showed variance regarding contingency planning for MCI/MI, revisions of the plans, use of national triage guidelines, knowledge requirements, as well as haemostatic and tactical first aid skills training. Participation in interdisciplinary on-going life-threatening violence (PLIVO) exercises was high among Ambulance, Police and Fire/Rescue Emergency Services. Simulations of terrorist attacks or disasters with multiple injured the last five years were reported by 21/151 (14%) on a regional level and 74/151 (48%) on a local level. Evaluation routines after MCI/MI events were reported by half of the respondents (75/151) and 70/149 (47%) described a dedicated function to perform such evaluation. CONCLUSION: The study indicates considerable variance and gaps among Prehospital Rescue and Emergency Services in Norway regarding MCI/MI preparedness work, calling for national benchmarks, minimum requirements, follow-up routines of the organisations and future reassessments. Implementation of mandatory PLIVO exercises seems to have contributed to interdisciplinary exercises between Fire/Rescue, Police and Ambulance Emergency Service. Repeated standardised surveys can be a useful tool to assess and follow-up the MI preparedness work among Prehospital Rescue and Emergency Services at a national, regional and local level.

Enhanced Communication for Interhospital Transfers Increases Preparedness in an Academic Tertiary Care Center.

OBJECTIVES: This quality improvement project sought to enhance clinical information sharing for interhospital transfers to an inpatient hepatology service comprised of internal medicine resident frontline providers (housestaff) with the specific aims of making housestaff aware of 100% of incoming transfers and providing timely access to clinical summaries. INTERVENTIONS: In February 2020, an email notification system to senior medicine residents responsible for patient triage shared planned arrival time for patients pending transfer. In July 2020, a clinical data repository ("Transfer Log") updated daily by accepting providers (attending physicians and subspecialty fellows) became available to senior medicine residents responsible for triage. METHODS: Likert scale surveys were administered to housestaff before email intervention (pre) and after transfer log intervention (post). The time from patient arrival to team assignment (TTA) in the electronic medical record was used as a proxy for time to patient assessment and was measured pre- and postinterventions; >2 hours to TTA was considered an extreme delay. RESULTS: Housestaff reported frequency of access to clinical information as follows: preinterventions 4/31 (13%) sometimes/very often and 27/31 (87%) never/rarely; postinterventions 11/26 (42%) sometimes/very often and 15/26 (58%) never/rarely (p = 0.02). Preinterventions 12/39 (31%) felt "not at all prepared" versus 27/39 (69%) "somewhat" or "adequately"; postinterventions 2/24 (8%) felt "not at all prepared" versus 22/24 (92%) somewhat/adequately prepared (p = 0.06). There was a significant difference in mean TTA between pre- and posttransfer log groups (62 vs. 40 minutes, p = 0.01) and a significant reduction in patients with extreme delays in TTA post-email (18/180 pre-email vs. 7/174 post-email, p = 0.04). CONCLUSION: Early notification and increased access to clinical information were associated with better sense of preparedness for admitting housestaff, reduction in TTA, and reduced frequency of extreme delays in team assignment.
