Level of Evidence Analysis for the Latest German National Guideline on Treatment of Patients with Severe and Multiple Injuries and ATLS

Performing Advanced Trauma Life Support (ATLS) across Borders: Midterm Follow-Up of the Aeromedical Evacuation after Civilian Bus Accident at Madeira

On 17 April 2019, a coach with tourists from Germany crashed in Madeira, requiring repatriation by the German Air Force. The Advanced Trauma Life Support (ATLS) concept was the central component of patient care. Data in Madeira were collected through a structured interview. The analysis of the Aeromedical Evacuation was based on intensive care transport records. In Germany, all available medical data sheets were reviewed for data collection. Quality of life (HRQoL) was evaluated by the 12-item Short Form Health Survey (SF-12). Twenty-eight prehospital patients were transported to the Level III Trauma Center in Funchal (Madeira). Five operative procedures were performed. Fifteen patients were eligible for Aeromedical Evacuation (AE). In the second hospital phase in Germany, in total 82 radiological images and 9 operations were performed. Hospital stay lasted 11 days (median, IQR 10-18). Median follow-up (14 of 15 patients) was 16 months (IQR 16-21). Eighty percent (8 out of 10) showed an increased risk for post-traumatic stress disorder (PTSD). Six key findings were identified in this study: divergent injury classification, impact of AE mission on health status, lack of communication, need of PTSD prophylaxis, patient identification, and media coverage. Those findings may improve AE missions in the future, e.g., when required after armed conflicts.

Comparison of manual statements from out-of-hospital trauma training programs and a national guideline on treatment of patients with severe and multiple injuries

PURPOSE

Training programs help establish evidence-based knowledge in prehospital emergency care. This study aimed to compare manual statements from prehospital trauma training programs and evidence-based guidelines on treatment of patients with severe and multiple injuries.

METHODS

A systematic comparison with the primary endpoint of the highest grades of recommendation (GoR A, "must") of the current version of the German guidelines and recent recommendations of the prehospital trauma training programs International Trauma Life Support (ITLS), Prehospital Trauma Life Support (PHTLS), and Traumamanagement^® (TM) based on their official textbooks was done. The recommendations were categorized as agreement or minor or major variation. The comparison was made using a rating system by experts who were blinded to the training programs. If the consensus strength of the experts was  < 75%, affected statements were finalized in a Delphi procedure.

RESULTS

Overall, 92 statements were compared. Fleiss-kappa of the first rating was 0.385 (p < 0.001, 95% CI: 0.376-0.393). Finally, comparable recommendations of the guideline with the training programs in principle agree with the statement of the guidelines were  > 90% for all programs. The agreement with GoR A recommendations and each course program were 33.9%, 30.6%, and 35.5% (ITLS, PHTLS, and TM, respectively), p = 0.715.

CONCLUSIONS

Despite small differences, the training programs showed high degrees of compliance with the guidelines and international agreement with some minor differences. Furthermore, the results did not allow any conclusions regarding the quality of the courses, the didactic methodology, and local adaptability. The practical implementation of the courses is probably even higher and closer to the guidelines.

Prevention and management of aggressive behaviour in patients at psychiatric hospitals: a document analysis of clinical practice guidelines in Hong Kong

Patient aggressive behaviour remains a significant public health concern worldwide. The use of restraint and seclusion remains a last resort but not an uncommon practice in clinical psychiatry in the management of aggressive events. There seems to be a paucity of evidenced-based research examining the policy framework guiding the use of restraint and seclusion in Asia contexts. The purpose of this study was to conduct an analysis on the guidelines in psychiatric hospitals in Hong Kong, and to explore the extent to which these guidelines were aligned with the international clinical guidelines for the prevention and management of patient aggression in psychiatry. A descriptive document analysis was used to analyse the guidelines from four psychiatric hospitals in Hong Kong in comparison with the NICE (National Institute of Health and Care Excellence UK) guidelines. Data were collected from December 2017 to June 2018. A total of 91 written documents were retrieved. Preventing violence and aggression has the highest level of agreement (31%,) while the use of restrictive interventions has the lowest level of agreement (12%). The sub-recommendation with most in line with the NICE guidelines were restrictive interventions, de-escalation, and improving service users' experiences. However, for example, staff training, working with police, and reduced use of restrictive interventions seemed to have no agreement with the NICE guidelines. Variation exists between the Asian (Hong Kong) local policy framework/guidelines and the European (UK) national policy framework. There are also large discrepancies in the written guidelines on patient aggressive behaviour when comparing local policy frameworks, cluster-based documents, and departmental practices.

Quality and utilization of the Finnish clinical practice guideline in schizophrenia: evaluation using AGREE II and the vignette approach

PURPOSE

This study aims to evaluate the quality of the Finnish clinical practice guideline related to schizophrenia care and how it can be utilized in psychiatric services.

PARTICIPANTS AND METHODS

The data were collected from one psychiatric ward and seven psychiatric outpatient units situated in two cities in Southern Finland. A total of 49 professionals working in these sites participated in this study. A descriptive study design was adopted. The Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument with six domains including 23 items was used to assess the quality of the guideline, whereas a vignette was implemented to describe how staff would use the guideline in hypothetical cases in daily practice. The analysis of AGREE II was based on rating each of the 23 items on a seven-point scale and calculating a quality score for the six domains. To describe the utilization of the guideline, eight key recommendations of the guideline were deductively rated out of the respondents' answers.

RESULTS

The results showed that the "scope and purpose" of the guideline were well described, but "applicability" was insufficient. The overall quality of the guideline was high (73%). Almost one fifth of the respondents were in agreement with key recommendations.

CONCLUSION

The overall quality of Guideline for Schizophrenia was good, but its "applicability" and utilization should be improved.

Performance Assessment of Emergency Teams and Communication in Trauma Care (PERFECT checklist)-Explorative analysis, development and validation of the PERFECT checklist: Part of the prospective longitudinal mixed-methods EPPTC trial

BACKGROUND

Trainings in emergency medicine are well structured, but examinations are rarely validated. We are evaluating the impact of pre-hospital emergency trainings on participants and patient care and developed and validated a checklist to assess emergency trainings.

METHODS

We used videos recorded at the time points directly before (t0), directly after (t1), and one year after (t2) training to develop the PERFECT checklist (Performance Assessment of Emergency Teams and Communication in Trauma Care). The videos were assessed using semi-qualitative/linguistic analysis as well as expert panel appraisal and recommendations using the Delphi method. The checklist was tested for validity and reliability.

RESULTS

The inter-rater reliability (ICC = 0.99) and internal consistency (α = 0.99) were high. Concurrent validity was moderate to high (r = 0.65 -r = 0.93 (p<0.001)). We included scales for procedures, non-technical skills, technical skills and global performance. The procedures were done faster in the mean over the timeline (t0: 2:29, 95%CI 1:54-3:03 min., t1: 1:11, 95%C 0:53-1:30 min, t2: 1:14, 95%CI 0:56-1:31 min.). All experts rated the recorded scenarios at t0 with the lowest sum score (mean 31±8), with a significantly better performance of the teams at t1 (mean 69±7). The performance at t2 (mean 66 ± 13) was slightly lower than at t1, but still better than at t0. At t1 and t2, linguistic analysis showed a change in the team leaders communication behaviour, which can be interpreted as a surrogate parameter for reduced stress.

CONCLUSION

The PERFECT checklist has a good validity and high reliability for assessing trauma procedures and teamwork.

Comparison of the Prehospital Trauma Life Support recommendations and the German national guideline on treatment of patients with severe and multiple injuries

BACKGROUND

The Prehospital Trauma Life Support (PHTLS) concept is well established throughout the world. The aim is to improve prehospital care for patients with major trauma. In 2011, a German Level 3 (S3) evidence- and consensus-based guideline on the treatment of patients with severe and multiple injuries was published. The scope of this study was the systematic comparison between the educational content of the worldwide PHTLS concept and the German S3 Guideline.

METHODS

A total of 62 key recommendations of the German S3 Guideline were compared with the content of the English PHTLS manual (eighth edition). Depending on the level of agreement, the recommendations were categorized as (1) agreement, (2) minor variation, or (3) major variation. Comparison was done via a rating system by a number of international experts in the field of out-of-hospital trauma care. The Delphi method was used to get the final statements by indistinct or board-ranged ratings.

RESULTS

Overall, there was no conformity in 12%. In 68% a total agreement and in 88% conformity with slight differences of minor variations were found between the key recommendations of the guideline and the PHTLS manual. The PHTLS primary assessment has a large conformity for the following individual priorities: airway, 92%; breathing, 92%; circulation, 63%; disability, 100%; exposure, 89%.

CONCLUSIONS

According to our comparison, the PHTLS manual is largely compatible with the German S3 Guideline from 2011. The 12% divergent statements concern mainly fluid resuscitation. Minor deviations in the prehospital care are due to a national guideline with an emergency medical service with emergency physicians (S3 Guideline) and a global PHTLS concept.

Benefits of Initial Limited Crystalloid Resuscitation in Severely Injured Trauma Patients at Emergency Department

Background

Whether initial limited crystalloid resuscitation (LCR) benefits to all severely injured trauma patients receiving blood transfusions at emergency department (ED) is uncertain. We aimed to determine the role of LCR and its associations with packed red blood cell (PRBC) transfusion during initial resuscitation.

Methods

Trauma patients receiving blood transfusions were reviewed from 2004 to 2013. Patients with LCR (L group, defined as < 2,000 mL) and excessive crystalloid resuscitation (E group, defined as ≥ 2,000 mL) were compared separately in terms of basic demographic, clinical variables, and hospital outcomes. Logistic regression, R-square (R²), and Spearman rho correlation were used for analysis.

Results

A total of 633 patients were included. The mortality was 51% in L group and 45% in E group (P = 0.11). No statistically significant difference was found in terms of basic demographics, vital signs upon arrival at ED, or injury severity between the groups. The volume of blood transfused strongly correlated with the volume of crystalloid infused in E group (R² = 0.955). Crystalloid to PRBC (C/PRBC) ratio was 0.8 in L group and 1.3 in E group (P < 0.01). The correlations between C/PRBC and ED versus ICU versus hospital length of stay (LOS) via Spearman rho were 0.25, 0.22, and 0.22, respectively.

Conclusions

Similar outcomes were observed in trauma patients receiving blood transfusions regardless of the crystalloid infusion volume. More crystalloid infusions were associated with more blood transfusions. The C/PRBC did not demonstrate predictive value regarding mortality but might predict LOS in severely injured trauma patients.
