Advanced training in trauma life support for ambulance crews

Impact of advanced trauma life support training on 30-day mortality in severely injured patients at a Kenyan tertiary center: a retrospective matched case-control study

INTRODUCTION

Trauma is a leading cause of mortality worldwide, particularly in low and middle-income countries (LMICs) like Kenya. This study evaluates the impact of Advanced Trauma Life Support (ATLS) training on 30-day mortality outcomes in severely injured patients at a tertiary care center in Kenya.

METHODS

A retrospective matched case-control study was conducted at Aga Khan University Hospital, Nairobi. The study included adult patients (≥ 18 years) with polytrauma (Injury Severity Score [ISS] > 15) from 2011 to 2022. Propensity score matching was used to pair 81 post-ATLS cases with 81 pre-ATLS controls based on age and ISS. Data analysis was performed using R Statistical language (version 4.3.0).

RESULTS

The 30-day mortality rate decreased significantly from 17% (95% CI: 9.4-27.4%) pre-ATLS to 6% (95% CI: 2.0-13.5%) post-ATLS (p = 0.028). No significant differences were found in baseline characteristics between the two groups. Road traffic accidents were the primary cause of trauma in both groups (72% pre-ATLS vs. 78% post-ATLS).

CONCLUSION

ATLS training significantly reduced 30-day mortality in severely injured patients, demonstrating its effectiveness even in resource-limited settings. Further prospective randomized studies are recommended to confirm these findings and evaluate long-term outcomes.

Evaluation of Current and Future Medical Staff Knowledge on the Course of Trauma Patient Management

INTRODUCTION

Management of injuries, especially in life-threatening situations, is critical to morbidity and mortality for trauma patients. The qualifications of medical staff and students in medicine, emergency medical services, and nursing help to ensure consistent, high-quality care for patients. The study aimed to assess the knowledge of our staff and learners in the management of trauma patients.

MATERIAL AND METHODS

The study was carried out using a proprietary research tool consisting of 47 questions, including six independent variables. The knowledge assessment tool has been divided into five categories according to the degree of difficulty. The questions have been created based on the current guidelines of the ERC 2021, ITLS, PTLS, and TCCC.

RESULTS

The study included 295 subjects (medical students, nursing students, students of emergency medical services, physicians, paramedics, and nurses). The vast majority of respondents (79.7%) have never participated in a certified trauma course. Respondents could obtain a total of 117 points for answering all questions. The highest score was 111 points, and the lowest was 26 points. The average score was 63 points. Paramedics received the highest average score of 78 points. The question with the smallest number of correct answers concerned the priority procedure in the case of an electric shock victim.

CONCLUSION

Better training in trauma patient management is needed for both current medical staff and students. A certified trauma course is a good source of knowledge and skills, but it would need to be repeated periodically. This would ensure an increase in the competence of medical staff involved in the care of trauma patients.

Quality assessment in initial paediatric trauma care: Systematic review from prehospital care to the paediatric intensive care unit

BACKGROUND

Trauma is the most common cause of death and disability in the paediatric population. There are a huge number of variables involved in the care they receive from health care professionals.

AIM

The aim of this study was to review the available evidence of initial paediatric trauma care throughout the health care process with a view to create quality indicators (QIs).

STUDY DESIGN

A systematic review was performed from Cochrane Library, Medline, Scopus and SciELO between 2010 and 2020. Studies and guidelines that examined quality or suggested QI were included. Indicators were classified by health care setting, Donabedian's model, risk of bias and the quality of the publication with the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) assessment.

RESULTS

The initial search included 686 articles, which were reduced to 22, with 15 primary and 7 secondary research articles. The snowball sampling technique was used to add a further seven guidelines and two articles. From these, 534 possible indicators were extracted, summarizing them into 39 and grouping the prehospital care indicators as structure (N = 5), process (N = 12) and outcome (N = 3) indicators and the hospital care indicators as structure (N = 4), process (N = 10) and outcome (N = 6) indicators. Most of the QIs have been extracted from US studies. They are multidisciplinary and in some cases are based on an adaptation of the QIs of adult trauma care.

CONCLUSIONS

There was a clear gap and large variability between the indicators, as well as low-quality evidence. Future studies will validate indicators using the Delphi method.

RELEVANCE TO CLINICAL PRACTICE

Design a QI framework that may be used by the health system throughout the process. Indicators framework will get nurses, to assess the quality of health care, detect deficient areas and implement improvement measures.

Challenges to the development of the trauma system in Egypt

Trauma is a hidden disease in Egypt, and its significance on public health has been underestimated for decades. Road traffic accidents are the leading cause of injuries presented to hospitals in Egypt. Trauma systems in developed countries effectively reduced the morbidity and mortality associated with injuries in crowded cities. Developing a trauma system in Egypt is mandatory with the exploding population growth, increasing incidence of injuries, and the vast expansion of the infrastructures in the road network. However, the implementation of the trauma system in Egypt will not be devoid of challenges, including a lack of mandatory healthcare infrastructures such as adequate pre-hospital care, poor quality of data, and a shortage of adequately trained emergency physicians across the country.

The effect of Helicobacter pylori eradication on C-reactive protein: results from a meta-analysis

Introduction

Helicobacter pylori is a bacterium that causes chronic gastroduodenal infection and affects various systemic diseases. An increase in the blood level of C-reactive protein (CRP; a systemic inflammatory marker), at a low-grade chronic inflammation level, is observed in cases of infection. However, the effect of H. pylori eradication on CRP remains undetermined. Therefore, we aimed to evaluate the circulating CRP levels in eradicated patients through a meta-analysis.

Material and methods

The PubMed database was searched from its inception to June 2020. Studies that described the CRP levels following H. pylori eradication were collected. A random-effects meta-analysis was then performed using inverse variance with standardized mean difference.

Results

A total of 10 eligible studies (642 subjects in total) were available. The median age in the studies was 49.9 years. The CRP level was 6.0 (median) mg/l before H. pylori eradication and 5.8 (median) mg/l after eradication. From the results of the overall meta-analysis, there was found to be a significant reduction in the CRP levels with H. pylori eradication (standardized mean difference: -0.64; 95% confidence interval: -1.02 to -0.27). The result was not similarly confirmed in a subanalysis of the available randomized controlled trials.

Conclusions

Weak evidence exists regarding the effects of H. pylori eradication on CRP levels. Further research is called for.

The Effect of Helicobacter pylori Eradication on Lipid Levels: A Meta-Analysis

Introduction:Helicobacter pylori (H. pylori) infection is positively associated with cardiovascular diseases, but the involvement of lipids in this association remains unclear. The present study reviewed the changes in circulating lipid levels following H. pylori eradication. Methods: A PubMed database was searched until December 2020 to identify randomized control trials (RCTs) and non-RCTs investigating the effect of H. pylori eradication on the lipid levels in inverse variance-weighted, random-effects meta-analyses. Results: A total of 24 studies (four RCTs and 20 non-RCTs) with 5270 participants were identified. The post-eradication levels were increased for high-density lipoprotein cholesterol (HDL-C; mean difference (MD) 2.28 mg/dL, 95% confidence interval (CI) 1.90 to 2.66) and triglyceride (TG; MD 3.22 mg/dL, 95% CI 1.13 to 5.31) compared with the pre-eradication levels. H. pylori eradication resulted in little to no difference in the low-density lipoprotein-cholesterol levels (MD −2.33 mg/dL, 95% CI −4.92 to 0.26). In the analyses of RCTs only, the findings for elevated HDL-C levels, but not TG, were robust. Conclusions:H. pylori eradication increases the HDL-C levels. Further studies are needed to elucidate the effects of lipid changes following H. pylori eradication on cardiovascular diseases.

The care and transport of trauma victims by layperson emergency medical systems: a qualitative study in Delhi, India

INTRODUCTION

Ambulance-based emergency medical systems (EMS) are expensive and remain rare in low- and middle-income countries, where trauma victims are usually transported to hospital by passing vehicles. Recent developments in transportation network technologies could potentially disrupt this status quo by allowing coordinated emergency response from layperson networks. We sought to understand the barriers to bystander assistance for trauma victims in Delhi, India, and implications for a layperson-EMS.

METHODS

We used qualitative methods to analyse data from 50 interviews with frontline stakeholders (including taxi drivers, medical professionals, legal experts and police), one stakeholder consultation and a review of documents.

RESULTS

Respondents noted that most trauma victims in Delhi are rapidly brought to hospital by bystanders, taxis and police. While ambulances are common, they are primarily used for interfacility transfers. Entrenched medico-legal practices result in substantial police presence at the hospital, which is a major source of harassment of good Samaritans and interferes with patient care. Trauma victims are often turned away by for-profit hospitals due to their inability to pay, leading to delays in treatment. Recent policy efforts to circumscribe the role of police and force for-profit hospitals to stabilise patients appear to have been unsuccessful.

CONCLUSIONS

Existing healthcare and medico-legal practices in India create large systemic impediments to improving trauma outcomes. Until India's ongoing health and transport sector reforms succeed in ensuring that for-profit hospitals reliably provide care, good Samaritans and layperson-EMS providers should take victims with uncertain financial means to public facilities. To avoid difficulties with police, providers of a layperson-EMS would likely need official police sanction and carry visible symbols of their authority to provide emergency transport. Delhi already has several key components of an EMS (including dispatcher coordinated police response, large ambulance fleet) that could be integrated and expanded into a complete system of emergency care.

[Cardiopulmonary resuscitation in cardiac arrest following trauma]

For decades, survival rates of cardiac arrest following trauma were reported between 0 and 2 %. Since 2005, survival rates have increased with a wide range up to 39 % and good neurological recovery in every second person injured for unknown reasons. Especially in children, high survival rates with good neurologic outcomes are published. Resuscitation following traumatic cardiac arrest differs significantly from nontraumatic causes. Paramount is treatment of reversible causes, which include massive bleeding, hypoxia, tension pneumothorax, and pericardial tamponade. Treatment of reversible causes should be simultaneous. Chest compression is inferior following traumatic cardiac arrest and should never delay treatment of reversible causes of the traumatic cardiac arrest. In massive bleeding, bleeding control has priority. Damage control resuscitation with permissive hypotension, aggressive coagulation therapy, and damage control surgery represent the pillars of initial treatment. Cardiac arrest due to hypoxia should be resolved by airway management and ventilation. Tension pneumothorax should be decompressed by finger thoracostomy, pericardial tamponade by resuscitative thoracotomy. In addition, resuscitative thoracotomy allows direct and indirect bleeding control. Untreated impact brain apnea may rapidly lead to cardiac arrest and requires quick opening of the airway and effective oxygenation. Established algorithms for treatment of cardiac arrest following trauma enable a safe, structured, and effective management.
