RESUMO
BACKGROUND: Prehospital blood gas analysis (BGA) is an evolving field that offers the potential for early identification and management of critically ill patients. However, the utility and accuracy of prehospital BGA are subjects of ongoing debate. OBJECTIVES: We aimed to provide a comprehensive summary of the current literature on prehospital BGA, including its indications, methods, and feasibility. METHODS: We performed a scoping review of prehospital BGA. A thorough search of the PubMed, Embase, and Web of Science databases was conducted to identify relevant studies focusing on prehospital BGA in adult patients. RESULTS: Fifteen studies met the inclusion criteria. Prehospital BGA was most frequently performed in patients in out-of-hospital cardiac arrest, followed by traumatic and nontraumatic cases. The parameters most commonly analyzed were pH, pCO2, pO2, and lactate. Various sampling methods, including arterial, venous, and intraosseous, were reported for prehospital BGA. While prehospital BGA shows promise in facilitating early identification of critical patients and guiding resuscitation efforts, logistical challenges are to be considered. The handling of preclinical BGA is described as feasible and useful in most of the included studies. CONCLUSION: Prehospital BGA holds significant potential for enhancing patient care in the prehospital setting, though technical challenges need to be considered. However, further research is required to establish optimal indications and demonstrate the benefits for prehospital BGA in specific clinical contexts.
RESUMO
Background: Hyperkalaemia is a common electrolyte abnormality seen in critically ill patients. In haemorrhagic shock, it may contribute to cardiac arrest and has been identified as a potential marker for tissue hypoxia. However, the significance of its role in haemorrhagic shock and its contribution to mortality remains unclear. This study aimed to examine the potential underlying pathophysiology and evaluate the incidence and characteristics of patients with hyperkalaemia on hospital arrival in bleeding trauma patients before transfusions and its mortality. Methods: A retrospective cohort study was conducted on adult patients with traumatic bleeding admitted to a European Major Trauma Centre between January 2016 and December 2021. Patients were classified according to their serum potassium levels on arrival, and relevant clinical parameters between non-hyperkalaemic and hyperkalaemic patients were compared. Results: Among the 83 patients in this study, 8 (9.6 %) presented with hyperkalaemia on arrival. The median shock index showed a higher tendency in the hyperkalaemic group. Hyperkalaemia was found to be more common among younger patients who sustained penetrating trauma. Mortality rates were higher in the hyperkalaemic group, but the difference was not statistically significant. Conclusion: Our results suggest that hyperkalaemia occurs frequently in bleeding trauma patients on hospital arrival pre-transfusions, indicating a more severe illness. Our findings provide insights into the pathophysiology and characteristics of hyperkalaemia in bleeding trauma patients. Further studies are required to investigate the mechanisms by which hyperkalaemia contributes to mortality in haemorrhagic shock patients.
RESUMO
BACKGROUND: The assessment of illness severity in the prehospital setting is essential for guiding appropriate medical interventions. The National Advisory Committee for Aeronautics (NACA) score is a validated tool commonly used for this purpose. However, the potential benefits of using bitemporal documentation of NACA scores to capture the dynamic changes in emergency situations remain uncertain. The objective of this study was to evaluate the potential benefit of bitemporal NACA score documentation in the prehospital setting, specifically in assessing the dynamic changes of emergencies and facilitating quality improvement through enhanced documentation practices. METHODS: In this retrospective study, data from prehospital emergency patients were analyzed who received care from the physician response unit between January 1, 2018, and May 31, 2021. Patient demographics, NACA scores, indications for emergency care, and changes in NACA scores were extracted from medical records. Statistical analyses were performed to examine the associations between NACA scores, emergency categories, indications, and changes in NACA scores. RESULTS: The study included 4005 patients, predominantly categorized as NACA III (33.7% at initial assessment, 41.8% at subsequent assessment) and NACA IV (31.6% at initial assessment, 22.4% at subsequent assessment). There was a significant improvement in NACA scores during the provision of prehospital care (p < 0.01). Notably, prehospital emergencies attributed to internal medical, neurological, traumatic, and paediatric causes demonstrated significant improvements in NACA scores (p < 0.01). Gender-specific differences were also observed. CONCLUSION: Our study suggests that the bitemporal documentation of NACA scores can be advantageous in the prehospital setting and may have implications for research, practice, and policy.
RESUMO
OBJECTIVES: To compare shared decision making (SDM) and satisfaction with care (SWC), an indicator of care quality, between children with special healthcare needs (CSHCN) and parents and to assess the association between SDM and SWC in both groups. METHODS: We recruited CSHCN ≥ 7 years and parents from 15 outpatient facilities that completed a paper questionnaire assessing SDM (highest vs. lower levels of SDM) and SWC. Differences in SDM and SWC were assessed with McNemar and paired t-tests. We used adjusted linear mixed models to investigate cross-sectional associations between SDM and SWC. RESULTS: Based on data from 275 CSHCN and 858 parents, 39% and 64% of CSHCN and parents reported the highest level of SDM (p < 0.0001). No difference in SWC was observed (p = 0.36). Perceived SDM was associated with SWC in both groups (both p < 0.0001). CONCLUSION: Associations between SDM and SWC reinforce the role of SDM for care quality. Large proportions of CSHCN and parents reporting suboptimal levels of SDM highlight the need for effective programs to promote SDM in the target population. PRACTICE IMPLICATIONS: Until effective programs become available, healthcare professionals can use existing opportunities to involve CSHCN and parents in consultations (e.g., provide sufficient opportunities to ask questions).

OBJECTIVE: To assess the extent of perceived shared decision making (SDM) with parents of pediatric patients and to examine its association with characteristics of patients, professionals, and healthcare facilities. METHODS: Parents of pediatric patients (n = 4383) were recruited in 15 social pediatric centers in Germany and provided information on perceived SDM (binary CollaboRATEpediatric score: optimal versus suboptimal extent of SDM), child age and sex, type of impairment, appointment, and healthcare professional present at the appointment. Organizational characteristics were assessed in a cross-sectional survey of staff at the study sites. RESULTS: Overall, 58.4% of parents reported an optimal extent of SDM. The optimal extent of SDM was more likely reported by parents of girls (OR=1.27, p < 0.001) and children with physical (as opposed to cognitive and combined) impairments (OR=1.30, p = 0.006), and after appointments attended by allied health professionals (OR=1.28, p = 0.004). In addition, parents in facilities receiving financing in addition to compensation by statutory health insurance funds were less likely to report an optimal extent of perceived SDM. CONCLUSION: While SDM with parents was mostly related to individual characteristics of children and professionals at appointments, organizational characteristics seemed less relevant in our study. PRACTICE IMPLICATIONS: Staff should be made aware of lower SDM with parents of boys, older children, and those with cognitive impairments, and trained to improve the SDM in these groups.

OBJECTIVES: Blood gas analysis, including parameters like lactate and base excess (BE), is crucial in emergency medicine but less commonly utilized prehospital. This study aims to elucidate the relationship between lactate and BE in various emergencies in a prehospital setting and their prognostic implications. METHODS: We conducted a retrospective analysis of prehospital emergency patients in Graz, Austria, from October 2015 to November 2020. Our primary aim was to assess the association between BE and lactate. This was assessed using Spearman's rank correlation and fitting a multiple linear regression model with lactate as the outcome, BE as the primary covariate of interest and age, sex, and medical emergency type as confounders. RESULTS: In our analysis population (n=312), lactate and BE levels were inversely correlated (Spearman's ρ, -0.75; p<0.001). From the adjusted multiple linear regression model (n=302), we estimated that a 1â¯mEq/L increase in BE levels was associated with an average change of -0.35 (95â¯% CI: -0.39, -0.30; p<0.001) mmol/L in lactate levels. Lactate levels were moderately useful for predicting mortality with notable variations across different emergency types. CONCLUSIONS: Our study highlights a significant inverse association between lactate levels and BE in the prehospital setting, underscoring their importance in early assessment and prognosis in emergency care. Additionally, the findings from our secondary aims emphasize the value of lactate in diagnosing acid-base disorders and predicting patient outcomes. Recognizing the nuances in lactate physiology is essential for effective prehospital care in various emergency scenarios.

INTRODUCTION: Since 2015, the Federal Joint Committee (G-BA)'s Innovation Fund has been supporting projects in health services research and new health service models ("Neue Versorgungsformen", NVF). By the end of 2022, 211 projects in the NVF category had been funded. A key objective is the transfer of successful projects into standard care. This article analyzes previous projects regarding their incorporation into routine care based on transfer recommendations of the Innovation Fund Committee ("Innovationsausschuss" IA). METHOD: Descriptive analysis of all projects completed by August 1, 2023 with transfer recommendations in the "NVF" funding stream. Presentation by topic, project duration, time until IA transfer decision, categorization, and number of institutions and organizations (recipients) addressed per project, their feedback published on the G-BA website, response rates per recipient group, and a content classification and interpretation of exemplary feedback. Recommendations based on the results and their discussion in an expert workshop. RESULTS: Out of 57 NVF projects, 17 had a transfer recommendation. A total of 57 feedback responses were received from a total of 431 recipients addressed by the IA across these projects. Response rates varied significantly. One-third of inquiries to the G-BA and its member organizations received a response (31%), while only every fifth inquiry to federal states (18%) and professional societies (18%) got a response. Less than one in ten inquiries to the Federal Ministry of Health (8%), administrative bodies (6%), and the German Medical Association (0%) received a response. Project-specific feedback within a recipient group was often contradictory or limited to regional scope. DISCUSSION AND CONCLUSION: The transfer process reveals significant structural and procedural obstacles regarding the incorporation of projects evaluated as successful into routine health care. To ensure that funding from the innovation fund is most effectively used, there needs to be a realistic chance of successful transfer of positive project outcomes into routine care. The DNVF recommends stronger involvement of rule-competent institutions, mandatory publication of responses, structured moderation of the transfer process, expanding types of selective contracts, financing of implementation phases and of studies drawing on results across successful NVF projects.
