A procedural check list for pleural decompression and intercostal catheter insertion for adult major trauma

The first hour of trauma reception is critical for patients with major thoracic trauma: A retrospective analysis from the TraumaRegister DGU

BACKGROUND

Up to 25% of trauma deaths are related to thoracic injuries.

OBJECTIVE

The primary goal was to analyse the incidence and time distribution of death in adult patients with major thoracic injuries. The secondary goal was to determine if potentially preventable deaths occurred within this time distribution and, if so, identify an associated therapeutic window.

DESIGN

Retrospective observational analysis.

SETTING

TraumaRegister DGU.

PATIENTS

Major thoracic injury was defined as an Abbreviated Injury Scale (AIS) 3 or greater. Patients with severe head injury (AIS ≥ 4) or injuries to other body regions with AIS being greater than the thoracic injury (AIS other >AIS thorax) were excluded to ensure that the most severe injury described was primarily thoracic related.

MAIN OUTCOME MEASURES

Incidence and time distribution of mortality were considered the primary outcome measures. Patient and clinical characteristics and resuscitative interventions were analysed in relation to the time distribution of death.

RESULTS

Among adult major trauma cases with direct admission from the accident scene, 45% had thoracic injuries and overall mortality was 9.3%. In those with major thoracic trauma ( n  = 24 332) mortality was 5.9% ( n  = 1437). About 25% of these deaths occurred within the first hour after admission and 48% within the first day. No peak in late mortality was seen. The highest incidences of hypoxia and shock were seen in non-survivors with immediate death within 1 h and early death (1 to 6 h). These groups received the largest number of resuscitative interventions. Haemorrhage was the leading cause of death in these groups, whereas organ failure was the leading cause of death amongst those who survived the first 6 h after admission.

CONCLUSION

About half of adult major trauma cases had thoracic injuries. In non-survivors with primarily major thoracic trauma, most deaths occurred immediately (<1h) or within the first 6 h after injury. Further research should analyse if improvements in trauma resuscitation performed within this time frame will reduce preventable deaths.

Standardized Protocol for Chest Tube Management for Trauma Patients Significantly Decreases Complications

Background

As health care shifts to a value-based model with a focus on patient outcomes per dollar spent, it is important to develop and evaluate standardized protocols that ultimately lead to improved patient outcomes and decreased hospital complications. Prior to our chest tube protocol, chest tube management at our Trauma Center was nonuniform and surgeon-specific. The aim of this study was to (1) develop an institutional standardized protocol for chest tube management at our Level II Trauma Center and (2) compare patient outcomes before and after the implementation of our protocol.

Methods

An institutional, standardized protocol was initiated at our Level II-Certified Trauma Center teaching hospital in 2014. An IRB-approved, single-institution retrospective chart review was performed between January 2011 and May 2017, in order to capture the 3 years prior and 3 years after protocol implementation. All patients with a diagnosis of hemothorax or pneumothorax (H/PTX) from blunt or penetrating trauma that resulted in a >24 French chest tube placement were included in the study. Patients were excluded if interventional radiology (IR) placed the chest tube, the mechanism was nontraumatic, or the patient expired at index hospitalization. Univariate analyses were performed to evaluate significant differences in patient outcomes before and after the implementation of the protocol.

Results

A total of 143 patients were analyzed for this study, with 43 preprotocol patients and 100 postprotocol patients. Hospital length of stay (LOS), persistent H/PTX, and the need for further surgical intervention all improved after the implementation of the standardized protocol (p < 0.04).

Conclusions

Our standardized protocol for chest tube management at our Level II Trauma Center significantly improved patient outcomes and can serve as a model for similar institutions.

Quality of Reporting on Guideline, Protocol, or Algorithm Implementation in Adult Trauma Centers: A Systematic Review

OBJECTIVE

To appraise the quality of reporting on guideline, protocol, and algorithm implementations in adult trauma settings according to the Revised Standards for Quality Improvement Reporting Excellence (SQUIRE 2.0).

BACKGROUND

At present we do not know if published reports of guideline implementations in trauma settings are of sufficient quality to facilitate replication by other centers wishing to implement the same or similar guidelines.

METHODS

A systematic review of the literature was conducted. Articles were identified through electronic databases and hand searching relevant trauma journals. Studies meeting inclusion criteria focused on a guideline, protocol, or algorithm that targeted adult trauma patients ≥18 years and/or trauma patient care providers, and evaluated the effectiveness of guideline, protocol, or algorithm implementation in terms of change in clinical practice or patient outcomes. Each included study was assessed in duplicate for adherence to the 18-item SQUIRE 2.0 criteria. The primary endpoint was the proportion of studies meeting at least 80% (score ≥15) of SQUIRE 2.0.

RESULTS

Of 7368 screened studies, 74 met inclusion criteria. Thirty-nine percent of studies scored ≥80% on SQUIRE 2.0. Criteria that were met most frequently were abstract (93%), problem description (93%), and specific aims (89%). The lowest scores appeared in the funding (28%), context (47%), and results (54%) criteria. No study indicated using SQUIRE 2.0 as a guideline to writing the report.

CONCLUSIONS

Significant opportunity exists to improve the utility of guideline implementation reports in adult trauma settings, particularly in the domains of study context and the implications of context for study outcomes.

Complications following chest tube insertion pre-and post-implementation of guidelines in patients with chest trauma: A retrospective, observational study

Background:

The need to evacuate the chest after a penetrating wound was first recognized in the 18^th century. Most thoracic injuries are treated with tube thoracostomy (TT) which refers to the insertion of a TT into the pleural cavity to drain air, blood, pus, or other fluids. However, TT has been challenged in the trauma care due to insertional, positional, or infective complications.

Methods:

A retrospective study of all trauma patients who had TT insertion from 2008 to 2014 was conducted based on the trauma registry data to describe patient characteristics, injury characteristics, management, and outcomes. The complication incidences per TT before (2008) and after (2009–2014) the implementation of standard protocol were compared.

Results:

During the study period, 804 patients were managed with 1004 TT procedures. The mean age was 34 years, and majority (91%) was males. Motor vehicle crash (43%) was the main mechanism of injury. Mean injury severity score was 22. The rib fractures (68%) were more frequent followed by pneumothorax (49%). Nearly 72% of patients received antibiotic coverage before insertion. The complications developed per TT reduced over the years from 2008 to 2014 (12.6% to 4.4%). The average complication per TT after the protocol implementation (2009–2014) reduced by 7% when compared to the duration before implementation (2008).

Conclusions:

The present study shows that standardized management of trauma patients who undergo TT results in a reduction in complications, helps improve patient flow, and ensures the proper management of resources in our high-volume trauma center.

How does the implementation of a patient pathway-based intervention in the acute care of blunt thoracic injury impact on patient outcomes? A systematic review of the literature

BACKGROUND

Blunt thoracic injury is present in around 15% of all major trauma presentations. To ensure a standardised approach to the management of physical injury, patient pathway-based interventions have been established in many healthcare settings. It currently remains unclear how these complex interventions are implemented and evaluated in the literature. This systematic review aims to identify pathway effectiveness literature and implementation studies in relation to patient pathway-based interventions in blunt thoracic injury care.

METHODS

The databases Medline, Embase, Web of Science, CINAHL, WHO Clinical Trials Register and both the GreyLit & OpenGrey databases were searched without restrictions on date or study type. A search strategy was developed including keywords and MeSH terms relating to blunt thoracic injury, patient pathway-based interventions, evaluation and implementation. Due to heterogeneity of intervention pathways, meta-analysis was not possible; analysis was undertaken using an iterative narrative approach.

RESULTS

A total of 16 studies met the inclusion criteria and were included in analysis. Pathways were identified covering analgesic management, respiratory care, surgical decision making and reducing risk of complications. Studies evaluating pathways are generally limited by their observational and retrospective design, but results highlight the potential benefits of pathway driven care provision in blunt thoracic injury.

CONCLUSIONS

The results demonstrate the complexity of evaluating patient pathway-based interventions in blunt thoracic injury management. It is important that pathways undergo rigorous evaluation, refinement and validation to ensure quality and patient safety. Strong recommendations are precluded as the quality of the pathway evaluation studies are low.

Finger thoracostomy in patients with chest trauma performed by paramedics on a helicopter emergency medical service

OBJECTIVE

To determine the frequency of finger thoracostomy performed by intensive care flight paramedics after the introduction of a training programme in this procedure and complications of the procedure that were diagnosed after hospital arrival.

METHODS

This was a retrospective cohort study of adult and paediatric trauma patients undergoing finger thoracostomy performed by paramedics on a helicopter emergency medical service between June 2015 and May 2018. Hospital data were obtained through a manual search of the medical records at each of the three receiving major trauma services. Additional data were sourced from the Victorian State Trauma Registry.

RESULTS

The final analysis included 103 cases, of which 73.8% underwent bilateral procedures with a total of 179 finger thoracostomies performed. The mean age of patients was 42.8 (standard deviation 21.4) years and 73.8% were male. Motor vehicle collision was the most common mechanism of injury accounting for 54.4% of cases. The median Injury Severity Score was 41 (interquartile range 29-54). There were 30 patients who died pre-hospital, with most (n = 25) having finger thoracostomy performed in the setting of a traumatic cardiac arrest. A supine chest X-ray was performed prior to intercostal catheter insertion in 38 of 73 patients arriving at hospital; of these, none demonstrated a tension pneumothorax. There were three cases of potential complications related to the finger thoracostomy.

CONCLUSION

Finger thoracostomy was frequently performed by intensive care flight paramedics. It was associated with a low rate of major complications and given the deficiencies of needle thoracostomy, should be the preferred approach for chest decompression.

Use of a Transfusion Checklist by Student Nurses to Improve Patient Safety

Better education around the recognition of transfusion-associated adverse events is warranted. It is unknown if checklist use improves recognition by student nurses. This study examined whether using a checklist could improve transfusion-associated adverse event recognition behaviors. There was an increased frequency of transfusion-associated adverse event management behaviors in the checklist group, but overall recognition was no greater than other groups. A transfusion-associated adverse event checklist may increase patient safety by promoting identification behaviors.

Thoracostomy in children with severe trauma: An overview of the paediatric experience in Victoria, Australia

OBJECTIVE

Thoracic trauma is a leading cause of paediatric trauma deaths. Traumatic cardiac arrest, tension pneumothorax and massive haemothorax are life-threatening conditions requiring emergency and definitive pleural decompression. In adults, thoracostomy is increasingly preferred over needle thoracocentesis for emergency pleural decompression. The present study reports on the early experience of thoracostomy in children, to inform debate regarding the best approach for emergency pleural compression in paediatric trauma.

METHODS

Retrospective review of Ambulance Victoria and The Royal Children's Hospital Melbourne, Trauma Registry between August 2016 and February 2019 to identify children undergoing thoracostomy for trauma, either pre-hospital or in the ED.

RESULTS

Fourteen children aged 1.2-15 years underwent 23 thoracostomy procedures over the 31 month period. The majority of patients sustained transport-related injuries, and underwent thoracostomies for the primary indications of hypoxia and hypotension. Two children were in traumatic cardiac arrest. Ten children underwent needle thoracocentesis prior to thoracostomy, but all required thoracostomy to achieve the necessary definitive decompression. All patients were severely injured with multiple-associated serious injuries and median Injury Severity Score 35.5 (17-75), three of whom died from their injuries. Thoracostomy in our cohort had a low complication rate.

CONCLUSION

In severely injured children, thoracostomy is an effective and reliable method to achieve emergency pleural decompression, including in the young child. The technical challenges presented by children are real, but can be addressed by training to support a low complication rate. We recommend thoracostomy over needle thoracocentesis as the first-line intervention in children with traumatic cardiac arrest, tension pneumothorax and massive haemothorax.

Could dental school teaching clinics provide better care than regular private practices?

Dental school clinics (DSC) consist of unlicensed dental students delivering care under the supervision of licensed dental professionals. Care delivery is slow due to inexperience of the provider and the series of supervisory checks that are necessary. Cost of care to the patient is less. To date, there has been no evaluation of the benefits of receiving care in a DSC beyond reduced fees. Research has shown the value of teaching hospitals in medicine, and the purpose of this article was to evaluate the total sum of benefits (the value proposition) of receiving dental care in a DSC.

Video-tube thoracostomy in trauma resuscitation: A pilot study

BACKGROUND

Complications related to incorrect positioning of tube thoracostomy (TT) have been reported to be as high as 30%. The aim of this study was to assess the feasibility of flexible videoscope guided placement of a pre-loaded chest tube, permitting direct intrapleural visualization and placement (Video-Tube Thoracostomy [V-TT]).

METHODS

A prospective, single centre, phase 1 pilot study with a parallel control group was undertaken. The population studied were adult thoracic trauma patients requiring emergency TT who were haemodynamically stable. The intervention performed was VTT. Patients in the control group underwent conventional TT. The primary outcome was tube position as defined by a consultant radiologist's interpretation of chest x-ray (CXR) or CT. The trial was registered with ANZCTR.org.au (ACTRN: 12,615,000,870,550).

RESULTS

There were 37 patients enrolled in the study - 12 patients allocated to the VTT intervention group and 25 patients allocated to conventional TT. Mean age of participants was 48 years (SD 15) in intervention group and 46 years (SD 15) years in the control group. In the VTT group all patients were male; the indications were pneumothorax (83%), haemothorax (8%) and haemopneumothorax (8%). The median injury severity score was 23 (16-28). There were 1 positional and 1 insertional complications. In the control group 72% of patients were male, the indications were pneumothorax (56%), haemothorax (4%) and haemopneumothorax (40%). The median injury severity score was 24 (14-36). There were 8 (32%) positional complications and no insertional complications.

CONCLUSION

V-TT was demonstrated to be a feasible alternative to conventional thoracostomy and merits further investigation.

A novel approach to improving the interpretation of CT brain in trauma

BACKGROUND

Computed tomography of the brain (CTB) has a fundamental role in the diagnosis and management of traumatic brain injury (TBI). There may be substantial discordance between initial CTB interpretation by emergency clinicians and the final radiology report. This study aimed to assess the utility of a structured reporting template in improving the accuracy of CTB interpretation by emergency clinicians.

METHOD

A prospective pre- and post-intervention cohort study was undertaken using a study population of emergency medicine trainees. The CTB reporting template was created with consultation from radiology, emergency medicine and trauma specialists. Participants reported on a set of randomly selected trauma CTBs first without, and then with, the reporting template. Each case was independently assessed for concordance with the radiology report by two blinded assessors (including a radiologist) and the proportion of concordant reports in each phase calculated.

RESULTS

There were 26 participants recruited to the study who reported on a total of 320 CTBs. In the pre-intervention phase, 121 (76%) cases were concordant with the radiology report compared to 147 (92%) post-intervention (p<0.01). The AUROC was 0.84 (95% CI: 0.78-0.89) pre-intervention and improved to 0.94 (95% CI: 0.88-0.99) with the intervention (p=0.01). A higher level of baseline accuracy was observed in advanced trainees (78%) compared to basic trainees (72%), but both improved to a similar level of 92% with the use of the CTB reporting template. There was a marked reduction in false negative errors, with increased identification of critical diagnoses such as cerebral herniation and diffuse axonal injury.

CONCLUSION

The use of the CTB reporting template significantly increased the accuracy of emergency medicine trainees and reduced the number of missed critical diagnoses. Reporting templates may represent an effective strategy to improve CTB interpretation and enhance the initial care of head injured patients.

Pleural procedural complications: prevention and management

Pleural disease is common with a rising case frequency. Many of these patients will be symptomatic and require diagnostic and/or therapeutic procedures. Patients with pleural disease present to a number of different medical specialties, and an equally broad range of clinicians are therefore required to have practical knowledge of these procedures. There is often underestimation of the morbidity and mortality associated with pleural interventions, even those regarded as being relatively straightforward, with potentially significant implications for processes relating to patient safety and informed consent. The advent of thoracic ultrasound (TUS) has had a major influence on patient safety and the number of physicians with the necessary skill set to perform pleural procedures. As the variety and complexity of pleural interventions increases, there is increasing recognition that early specialist input can reduce the risk of complications and number of procedures a patient requires. This review looks at the means by which complications of pleural procedures arise, along with how they can be managed or ideally prevented.
