Review
AIM
To review the evidence regarding non-transported older people who have fallen in relation to non-transportation rates, outcomes and impact of alternate care pathways.
METHOD
Electronic databases and reference lists of included studies (up to December 2011) were systematically searched. Studies were eligible if they included data on non-transportation rates, information on outcomes or alternate care pathways for older people who have fallen.
RESULTS
Twelve studies were included. Non-transportation rates following a fall ranged from 11% to 56%. Up to 49% of non-transported people who have fallen had unplanned health-care contact within 28 days of the initial incident. Attendance by specially trained paramedics and individualised multifactorial interventions significantly reduced adverse events including subsequent falls, emergency ambulance calls, emergency department attendance and hospital admission.
CONCLUSION
Limited but promising evidence shows that appropriate interventions can improve health outcomes of non-transported older people who have fallen. Further studies are needed to explore alternate care pathways and promote more efficient use of health services.

Review
BACKGROUND
There appears to be a paucity of studies examining the characteristics and impact of frequent users upon emergency medical services (EMS).
OBJECTIVE
To review current primary research on frequent users of EMS and to identify possible gaps in the literature.
METHODS
Ovid, PubMed and CINAHL/Medline were systematically searched for articles that were published in English and either referred to frequent callers to or users of an EMS, or referred to frequent users of other services where admissions were via ambulance. Studies were included regardless of quality.
FINDINGS
Eighteen studies were included. Ten were emergency department based, seven in EMS and one in a psychiatric emergency service. In emergency department studies, frequent users were more likely to arrive via ambulance than infrequent users. In EMS studies, between 0.2% and 23% of patients using EMS were frequent users accounting for 1.4% to 40% of all ambulance use. No two EMS studies used the same definition of a frequent user. No studies focused on characteristics of callers to EMS. Two studies explored interventions for frequent callers to EMS, with mixed results in reducing ambulance use.
DISCUSSION
It is unknown to what extent frequent callers impact upon EMS resources. Research should identify predictors and characteristics of frequent users of EMS, and a consistent definition of a frequent caller to or user of EMS would provide greater comparability. The lack of studies identified in this review suggests that further research is needed in order to inform policy and practice.

Review
BACKGROUND
The war in Tigray, North Ethiopia which started in November 2020, has destroyed decades of the region's healthcare success. There is some emerging published evidence on attacks on health care in the region, and we synthesized the available evidence on 'perilous medicine' in Tigray to understand the data source, subjects and content covered, and what gaps exist.
METHODS
We employed a systematic review and performed a systematic search of MEDLINE, PubMed, CINHAL, Web of Science and Scopus. We included English written documents published from 4 November 2020 to 18-19 October 2022 and updated the search on 23 January 2023. HG and NF independently performed title, abstract and full-text screening. We used Joanna Briggs Institute (JBI) tools to appraise and extract data, and applied content synthesis to analyze. The PROSPERO registration number is CRD42022364964.
RESULTS
Our systematic review search yielded 8,039 documents, and we finally found 41 documents on conflict and health in Tigray. The areas were: (1) attacks on infrastructure, health or aid workers, patients, ambulances or aid trucks identified in 29 documents-the documents reported targeted attacks on health infrastructure and personnel; (2) interruption of health or social services in 31 documents-the documents reported medical and humanitarian siege; (3) outcomes and direct or indirect impacts in 33 documents-the documents reported increased magnitude of illnesses, and catastrophic humanitarian crises including the use of food, medicine and rape as tools of war; and (4) responses, rebuilding strategies, and recommendations in 21 documents-the documents reported improvisation of services, and calling to seize fire, accountability and allow humanitarian.
CONCLUSIONS
Despite promising studies on conflict and health in Tigray, the documents lack quality of designs and data sources, and depth and diversity of subjects and contents covered; calling further primary studies on a prioritized future research agenda.

BACKGROUND
Rapid and accurate detection of stroke by paramedics or other emergency clinicians at the time of first contact is crucial for timely initiation of appropriate treatment. Several stroke recognition scales have been developed to support the initial triage. However, their accuracy remains uncertain and there is no agreement which of the scales perform better.
OBJECTIVES
To systematically identify and review the evidence pertaining to the test accuracy of validated stroke recognition scales, as used in a prehospital or emergency room (ER) setting to screen people suspected of having stroke.
SEARCH METHODS
We searched CENTRAL, MEDLINE (Ovid), Embase (Ovid) and the Science Citation Index to 30 January 2018. We handsearched the reference lists of all included studies and other relevant publications and contacted experts in the field to identify additional studies or unpublished data.
SELECTION CRITERIA
We included studies evaluating the accuracy of stroke recognition scales used in a prehospital or ER setting to identify stroke and transient Ischemic attack (TIA) in people suspected of stroke. The scales had to be applied to actual people and the results compared to a final diagnosis of stroke or TIA. We excluded studies that applied scales to patient records; enrolled only screen-positive participants and without complete 2 × 2 data.
DATA COLLECTION AND ANALYSIS
Two review authors independently conducted a two-stage screening of all publications identified by the searches, extracted data and assessed the methodologic quality of the included studies using a tailored version of QUADAS-2. A third review author acted as an arbiter. We recalculated study-level sensitivity and specificity with 95% confidence intervals (CI), and presented them in forest plots and in the receiver operating characteristics (ROC) space. When a sufficient number of studies reported the accuracy of the test in the same setting (prehospital or ER) and the level of heterogeneity was relatively low, we pooled the results using the bivariate random-effects model. We plotted the results in the summary ROC (SROC) space presenting an estimate point (mean sensitivity and specificity) with 95% CI and prediction regions. Because of the small number of studies, we did not conduct meta-regression to investigate between-study heterogeneity and the relative accuracy of the scales. Instead, we summarized the results in tables and diagrams, and presented our findings narratively.
MAIN RESULTS
We selected 23 studies for inclusion (22 journal articles and one conference abstract). We evaluated the following scales: Cincinnati Prehospital Stroke Scale (CPSS; 11 studies), Recognition of Stroke in the Emergency Room (ROSIER; eight studies), Face Arm Speech Time (FAST; five studies), Los Angeles Prehospital Stroke Scale (LAPSS; five studies), Melbourne Ambulance Stroke Scale (MASS; three studies), Ontario Prehospital Stroke Screening Tool (OPSST; one study), Medic Prehospital Assessment for Code Stroke (MedPACS; one study) and PreHospital Ambulance Stroke Test (PreHAST; one study). Nine studies compared the accuracy of two or more scales. We considered 12 studies at high risk of bias and one with applicability concerns in the patient selection domain; 14 at unclear risk of bias and one with applicability concerns in the reference standard domain; and the risk of bias in the flow and timing domain was high in one study and unclear in another 16.We pooled the results from five studies evaluating ROSIER in the ER and five studies evaluating LAPSS in a prehospital setting. The studies included in the meta-analysis of ROSIER were of relatively good methodologic quality and produced a summary sensitivity of 0.88 (95% CI 0.84 to 0.91), with the prediction interval ranging from approximately 0.75 to 0.95. This means that the test will miss on average 12% of people with stroke/TIA which, depending on the circumstances, could range from 5% to 25%. We could not obtain a reliable summary estimate of specificity due to extreme heterogeneity in study-level results. The summary sensitivity of LAPSS was 0.83 (95% CI 0.75 to 0.89) and summary specificity 0.93 (95% CI 0.88 to 0.96). However, we were uncertain in the validity of these results as four of the studies were at high and one at uncertain risk of bias. We did not report summary estimates for the rest of the scales, as the number of studies per test per setting was small, the risk of bias was high or uncertain, the results were highly heterogenous, or a combination of these.Studies comparing two or more scales in the same participants reported that ROSIER and FAST had similar accuracy when used in the ER. In the field, CPSS was more sensitive than MedPACS and LAPSS, but had similar sensitivity to that of MASS; and MASS was more sensitive than LAPSS. In contrast, MASS, ROSIER and MedPACS were more specific than CPSS; and the difference in the specificities of MASS and LAPSS was not statistically significant.
AUTHORS' CONCLUSIONS
In the field, CPSS had consistently the highest sensitivity and, therefore, should be preferred to other scales. Further evidence is needed to determine its absolute accuracy and whether alternatives scales, such as MASS and ROSIER, which might have comparable sensitivity but higher specificity, should be used instead, to achieve better overall accuracy. In the ER, ROSIER should be the test of choice, as it was evaluated in more studies than FAST and showed consistently high sensitivity. In a cohort of 100 people of whom 62 have stroke/TIA, the test will miss on average seven people with stroke/TIA (ranging from three to 16). We were unable to obtain an estimate of its summary specificity. Because of the small number of studies per test per setting, high risk of bias, substantial differences in study characteristics and large between-study heterogeneity, these findings should be treated as provisional hypotheses that need further verification in better-designed studies.

BACKGROUND
Within the UK, there are now opportunities for paramedics to work across a variety of healthcare settings away from their traditional ambulance service employer, with many opting to move into primary care.
AIM
To provide an overview of the types of clinical roles paramedics are undertaking in primary and urgent care settings within the UK.
DESIGN AND SETTING
A systematic review.
METHOD
Searches were conducted of MEDLINE, CINAHL, Embase, the National Institute for Health and Care Excellence, the , and the Cochrane Database from January 2004 to March 2019 for papers detailing the role, scope of practice, clinician and patient satisfaction, and costs of paramedics in primary and urgent care settings. Free-text keywords and subject headings focused on two key concepts: paramedic and general practice/primary care.
RESULTS
In total, 6765 references were screened by title and/or abstract. After full-text review, 24 studies were included. Key findings focused on the description of the clinical role, the clinical work environment, the contribution of paramedics to the primary care workforce, the clinical activities they undertook, patient satisfaction, and education and training for paramedics moving from the ambulance service into primary care.
CONCLUSION
Current published research identifies that the role of the paramedic working in primary and urgent care is being advocated and implemented across the UK; however, there is insufficient detail regarding the clinical contribution of paramedics in these clinical settings. More research needs to be done to determine how, why, and in what context paramedics are now working in primary and urgent care, and what their overall contribution is to the primary care workforce.

Review
Emergency services personnel have an elevated risk of developing mental health conditions. Most research in this area is cross-sectional, which precludes inferences about temporal and potentially causal relationships between risk and protective factors and mental health outcomes. The current study systematically reviewed prospective studies of risk and protective factors for mental health outcomes in civilian emergency services personnel (firefighters, paramedics, police) assessed at pre-operational and operational stages. Out of 66 eligible prospective studies identified, several core groups of risk and protective factors emerged: (1) cognitive abilities; (2) coping tendencies; (3) personality factors; (4) peritraumatic reactions and post-trauma symptoms; (5) workplace factors; (6) interpersonal factors; (7) events away from work. Although there was insufficient evidence for many associations, social support was consistently found to protect against the development of mental health conditions, and peritraumatic dissociation, prior mental health issues, and prior trauma exposure were risk factors for future mental health conditions. Among operational studies, neuroticism was significantly associated with future PTSD symptoms, burnout, and general poor mental health, and avoidance and intrusion symptoms of PTSD were associated with future PTSD and depression symptoms. The current review results provide important targets for future research and interventions designed to improve the mental health of emergency services personnel.

Meta-Analysis Review
BACKGROUND
Pre-hospital endotracheal intubation is frequently used for trauma patients in many emergency medical systems. Despite a wide range of publications in the field, it is debated whether the intervention is associated with a favourable outcome, when compared to more conservative airway measures.
METHODS
A systematic literature search was conducted to identify interventional and observational studies where the mortality rates of adult trauma patients undergoing pre-hospital endotracheal intubation were compared to those undergoing emergency department intubation.
RESULTS
Twenty-one studies examining 35,838 patients were included. The median mortality rate in patients undergoing pre-hospital intubation was 48% (range 8-94%), compared to 29% (range 6-67%) in patients undergoing intubation in the emergency department. Odds ratios were in favour of emergency department intubation both in crude and adjusted mortality, with 2.56 (95% CI: 2.06, 3.18) and 2.59 (95% CI: 1.97, 3.39), respectively. The overall quality of evidence is very low. Twelve of the twenty-one studies found a significantly higher mortality rate after pre-hospital intubation, seven found no significant differences, one found a positive effect, and for one study an analysis of the mortality rate was beyond the scope of the article.
CONCLUSIONS
The rationale for wide and unspecific indications for pre-hospital intubation seems to lack support in the literature, despite several publications involving a relatively large number of patients. Pre-hospital intubation is a complex intervention where guidelines and research findings should be approached cautiously. The association between pre-hospital intubation and a higher mortality rate does not necessarily contradict the importance of the intervention, but it does call for a thorough investigation by clinicians and researchers into possible causes for this finding.

Meta-Analysis Review
BACKGROUND
Early diagnosis through symptom recognition is vital in the management of acute stroke. However, women who experience stroke are more likely than men to be initially given a nonstroke diagnosis and it is unclear if potential sex differences in presenting symptoms increase the risk of delayed or missed stroke diagnosis.
AIMS
To quantify sex differences in the symptom presentation of stroke and assess whether these differences are associated with a delayed or missed diagnosis.
METHODS
PubMed, EMBASE, and the Cochrane Library were systematically searched up to January 2021. Studies were included if they reported presenting symptoms of adult women and men with diagnosed stroke (ischemic or hemorrhagic) or transient ischemic attack (TIA) and were published in English. Mean percentages with 95% confidence intervals (CIs) of each symptom were calculated for women and men. The crude relative risks (RRs) with 95% CI of symptoms being present in women, relative to men, were also calculated and pooled. Any data on the delayed or missed diagnosis of stroke for women compared to men based on symptom presentation were also extracted.
RESULTS
Pooled results from 21 eligible articles showed that women and men presented with a similar mean percentage of motor deficit (56% in women vs 56% in men) and speech deficit (41% in women vs 40% in men). Despite this, women more commonly presented with nonfocal symptoms than men: generalized nonspecific weakness (49% vs 36%), mental status change (31% vs 21%), and confusion (37% vs 28%), whereas men more commonly presented with ataxia (44% vs 30%) and dysarthria (32% vs 27%). Women also had a higher risk of presenting with some nonfocal symptoms: generalized weakness (RR 1.49, 95% CI 1.09-2.03), mental status change (RR 1.44, 95% CI 1.22-1.71), fatigue (RR 1.42, 95% CI 1.05-1.92), and loss of consciousness (RR 1.30, 95% CI 1.12-1.51). In contrast, women had a lower risk of presenting with dysarthria (RR 0.89, 95% CI 0.82-0.95), dizziness (RR 0.87, 95% CI 0.80-0.95), gait disturbance (RR 0.79, 95% CI 0.65-0.97), and imbalance (RR 0.68, 95% CI 0.57-0.81). Only one study linking symptoms to definite stroke/TIA diagnosis found that pain and unilateral sensory loss are associated with lower odds of a definite diagnosis in women compared to men.
CONCLUSION
Although women showed a higher prevalence of some nonfocal symptoms, the prevalence of focal neurological symptoms, such as motor weakness and speech deficit, was similar for both sexes. Awareness of sex differences in symptoms in acute stroke evaluation, careful consideration of the full constellation of presenting symptoms, and further studies linking symptoms to diagnostic outcomes can be helpful in improving early diagnosis and management in both sexes.

Review
BACKGROUND
This study addresses the critical issue of high-volume emergency calls in hospitals, focusing on the strain caused by frequent caller patients on ambulance services. The aim was to synthesize various management methods for handling high-frequency hospital calls.
METHODS
The systematic review was conducted following the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines and guided by the Cochrane Handbook for systematic reviews. Inclusion criteria encompassed studies focusing on the management of emergency departments in hospitals, exploring various medical conditions requiring ambulance attention, and reporting on the impact of a high volume of ambulance calls on hospitals. Databases including PubMed, Web of Science, and Google Scholar were searched from January 1, 2005, to May 1, 2022. The quality of included studies was assessed using the Critical Appraisal Skills Programme (CASP) Checklist.
RESULTS
Out of 2390 identified citations, 18 studies met the inclusion criteria. These studies, from 12 countries, presented diverse methods categorized into country policy-based management, modeling approaches, and general strategies. Key findings included the effectiveness of risk stratification models and community-based interventions in managing high call frequencies and improving patient care. Our review identified effective strategies such as risk stratification models and community-based interventions, which have shown significant impacts in managing high call frequencies, aligning closely with our objective. These approaches have been pivotal in reducing the burden on emergency services and improving patient care.
CONCLUSION
The study synthesizes effective management methods for high-frequency ambulance calls, including predictive modeling and community interventions. It highlights the need for multi-faceted management strategies in different healthcare settings and underscores the importance of continued research and implementation of these methods to improve emergency service efficiency.

Review
BACKGROUND
Cognitive impairment is a mental disorder that commonly affects elderly people. Serious games, which are games that have a purpose other than entertainment, have been used as a nonpharmacological intervention for improving cognitive abilities. The effectiveness and safety of serious games for improving cognitive abilities have been investigated by several systematic reviews; however, they are limited by design and methodological weaknesses.
OBJECTIVE
This study aims to assess the effectiveness and safety of serious games for improving cognitive abilities among elderly people with cognitive impairment.
METHODS
A systematic review of randomized controlled trials (RCTs) was conducted. The following 8 electronic databases were searched: MEDLINE, Embase, CINAHL, PsycINFO, ACM Digital Library, IEEE Xplore, Scopus, and Google Scholar. We also screened reference lists of the included studies and relevant reviews, as well as checked studies citing our included studies. Two reviewers independently carried out the study selection, data extraction, risk of bias assessment, and quality of evidence appraisal. We used a narrative and statistical approach, as appropriate, to synthesize the results of the included studies.
RESULTS
Fifteen studies met the eligibility criteria among 466 citations retrieved. Of those, 14 RCTs were eventually included in the meta-analysis. We found that, regardless of their type, serious games were more effective than no intervention (P=.04) and conventional exercises (P=.002) for improving global cognition among elderly people with cognitive impairment. Further, a subgroup analysis showed that cognitive training games were more effective than no intervention (P=.05) and conventional exercises (P<.001) for improving global cognition among elderly people with cognitive impairment. Another subgroup analysis demonstrated that exergames (a category of serious games that includes physical exercises) are as effective as no intervention and conventional exercises (P=.38) for improving global cognition among elderly people with cognitive impairment. Although some studies found adverse events from using serious games, the number of adverse events (ie, falls and exacerbations of pre-existing arthritis symptoms) was comparable between the serious game and control groups.
CONCLUSIONS
Serious games and specifically cognitive training games have the potential to improve global cognition among elderly people with cognitive impairment. However, our findings remain inconclusive because the quality of evidence in all meta-analyses was very low, mainly due to the risk of bias raised in the majority of the included studies, high heterogeneity of the evidence, and imprecision of total effect sizes. Therefore, psychologists, psychiatrists, and patients should consider offering serious games as a complement and not a substitute to existing interventions until further more robust evidence is available. Further studies are needed to assess the effect of exergames, the safety of serious games, and their long-term effects.
