A potential method of identifying stroke and other intracranial lesions in a prehospital setting.

ABSTRACT: BACKGROUND:Identifying stroke and other intracranial lesions in patients with a decreased level of consciousness may be challenging in prehospital settings. Our objective was to investigate whether the combination of systolic blood pressure, heart rate and age could be used to identify intracranial lesions. METHODS:We conducted a retrospective case-control study including patients with a decreased level of consciousness who had their airway secured during prehospital care. Patients with intracranial lesions were identified based on the final diagnoses at the end of hospitalization. We investigated the ability of systolic blood pressure, heart rate and age to identify intracranial lesions and derived a decision instrument. RESULTS:Of 425 patients, 127 had an intracranial lesion. Patients with a lesion were characterized by higher systolic blood pressure, lower heart rate and higher age (P??170?mmHg had an OR of 8.2 (95% CI 4.5-15.32) for an intracranial lesion (reference: ?70?years had an OR of 10.2 (95% CI 4.8 to 23.2), reference:

Project description:BackgroundTimely and appropriate hospital treatment of acute cerebrovascular diseases (stroke and Transient Ischemic Attacks - TIA) improves patient outcomes. Emergency Medical Service (EMS) dispatchers who can identify cerebrovascular disease symptoms during telephone requests for emergency service also contribute to these improved outcomes. The Italian Ministry of Health issued guidelines on the management of AC patients in pre-hospital emergency service, including Cincinnati Prehospital Stroke Scale (CPSS) use.We measured the sensitivity and Positive Predictive Value (PPV) of EMS dispatchers' ability to recognize stroke/TIA symptoms and evaluated whether the CPSS improves accuracy.MethodsA cross-sectional multicentre study was conducted to collect data from 38 Italian emergency operative centres on all cases identified with stroke/TIA symptoms at the time of dispatch and all cases with stroke/TIA symptoms identified on the scene by the ambulance personnel from November 2010 to May 2011.ResultsThe study included 21760 cases: 18231 with stroke/TIA symptoms at dispatch and 9791 with symptoms confirmed on the scene. The PPV of the dispatch stroke/TIA symptoms identification was 34.3% (95% CI 33.7-35.0; 6262/18231) and the sensitivity was 64.0% (95% CI 63.0-64.9; 6262/9791). Centres using CPSS more often (>10% of cases) had both higher PPV (56%; CI 95% 57-60 vs 18%; CI 95% 17-19) and higher sensitivity (71%; CI 95% 87-89 vs 52%; CI 95% 51-54).In the multivariate regression a centre's CPSS use was associated with PPV (beta 0.48 p = 0.014) and negatively associated with sensitivity (beta -0.36; p = 0.063); centre sensitivity was associated with CPSS (beta 0.32; p = 0.002), adjusting for PPV.ConclusionsCentres that use CPSS more frequently during phone dispatch showed greater agreement with on-the-scene prehospital assessments, both in correctly identifying more cases with stroke/TIA symptoms and in giving fewer false positives for non-stroke/TIA cases. Our study shows an extreme variability in the performance among OCs, highlighting that form many centres there is room for improvement in both sensitivity and positive predictive value of the dispatch. Our results should be used for benchmarking proposals in the effort to identify best practices across the country.

Project description:BackgroundAcute pain is a common reason for seeking prehospital emergency care. Regrettably, acute pain is often underestimated and poorly managed in this setting. The scoping review was conducted to gain insight into existing research on the topic and to make recommendations for future work.ObjectivesTo identify all available evidence related to acute pain assessment and management in the African prehospital setting, describe the extent of the evidence, encapsulate findings, and identify research gaps.MethodsThe scoping review considered primary and secondary research related to acute pain assessment and management of both medical and traumatic origins in all age groups in the African prehospital setting. The search strategy aimed to identify published, unpublished, and ongoing research which met the inclusion criteria. Potentially eligible studies were identified by a comprehensive search of electronic databases, trial registers, dissertation/thesis databases, grey literature databases, and conference proceedings. Screening and data extraction were conducted independently and in duplicate.ResultsThe comprehensive search identified 3823 potential studies, duplicate titles were removed, and 3358 titles/abstracts were screened. Full text of 66 potentially eligible titles was screened, 60 were excluded, and six publications met the inclusion criteria. Despite recommendations for pain assessment during general patient care, most studies reported no/limited pain assessment. In general, pain management was concluded to be insufficient and not conforming to best practice.ConclusionsOnly six publications addressing prehospital acute pain care in Africa could be identified, possibly indicative of a knowledge gap. Future research is indicated to enable a better understanding of the epidemiology of acute pain and barriers and enablers of acute pain care and to develop evidence-based clinical practice guidelines (CPGs) catering for all EMS systems in Africa. Additionally, educational initiatives should be implemented to improve the quality of acute pain care and to monitor quality through continuous quality improvement (CQI) programs.

Project description:IntroductionPrehospital haemorrhage control has saved thousands of lives in the military over the last decade. While uncontrolled haemorrhage is a leading cause of preventable injury death in the USA for individuals under 45, military prehospital haemorrhage control techniques have not fully translated to the civilian sector in the USA. The effective implementation of haemorrhage control for civilian prehospital trauma is dependent on a more complex array of system and personnel-level factors than the military.ObjectiveThis protocol describes the methodology of a scoping review on haemorrhage control strategies in the prehospital setting; specifically, education, logistics and implementation of these strategies. The aim of the review is to identify research gaps and create recommendations for future research surrounding prehospital layperson haemorrhage control.MethodsThe protocol uses the framework published by The Joanna Briggs Institute and Arksey and O'Malley, while following the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Review Protocols guidelines. The search strategy was refined with the help of a medical librarian. Three peer-reviewed databases (EMBASE, PubMed and Web of Science), databases dedicated to grey literature sources, and reference mining will be used. Two investigators will independently screen and extract data. Discrepancies will be resolved by a third investigator. The extracted data will undergo descriptive analysis of the contextual data and a quantitative analysis using the appropriate statistical methods. In addition, this search strategy will be supplemented by a grey literature search.Ethics and disseminationResearch ethics approval is not required for this scoping review. This scoping review will serve to highlight existing gaps within the literature to guide further research and develop future strategies to improve prehospital haemorrhage management. The results of this review will be presented at relevant national and international conferences and published in a peer-reviewed journal.
