[Severe polytrauma with an ISS ≥ 50]

The most critically injured polytrauma patient mortality: should it be a measurement of trauma system performance?

PURPOSE

The risk of death after traumatic injury in developed trauma systems is at an all-time low. Among 'major trauma' patients (injury severity score, ISS > 15), the risk of dying is less than 10%. This group contains critical polytrauma patients (ISS 50-75), with high risks of death. We hypothesized that the reduction in trauma mortality was driven by reduction in moderate injury severity and that death from critical polytrauma remained persistently high.

METHODS

A 20-year retrospective analysis ending December 2021 of a Level-1 trauma center's registry was performed on all trauma patients admitted with ISS > 15. Patients' demographics, injury severity and outcomes were collected. Multivariate logistic regression analysis was performed. Mortality was examined for the entire study group and separately for the subset of critical polytrauma patients (ISS 50-75).

RESULTS

A total of 8462 severely injured (ISS > 15) trauma patients were identified during the 20-year period. Of these 238 (2.8%) were critical polytrauma patients (ISS 50-75). ISS > 15 mortality decreased from 11.3 to 9.4% over the study period (Adjusted OR 0.98, 0.97-0.99). ISS 50-75 mortality did not change significantly (46.2-60.0%), adjusted OR 0.96, 0.92-1.00).

CONCLUSION

The improvement in trauma mortality over the past 20 years has not been experienced equally. The ISS50-75 critical polytrauma mortality is a practical group to capture. It could be a group for deeper study and reporting to drive improvement.

The outcomes of the most severe polytrauma patients: a systematic review of the use of high ISS cutoffs for performance measurement

BACKGROUND

This systematic review aimed to describe the outcomes of the most severely injured polytrauma patients and identify the consistent Injury Severity Score based definition of utilised for their definition. This could provide a global standard for trauma system benchmarking.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was applied to this review. We searched Medline, Embase, Cochrane Reviews, CINAHL, CENTRAL from inception until July 2022. Case reports were excluded. Studies in all languages that reported the outcomes of adult and paediatric patients with an ISS 40 and above were included. Abstracts were screened by two authors and ties adjudicated by the senior author.

RESULTS

7500 abstracts were screened after excluding 13 duplicates. 56 Full texts were reviewed and 37 were excluded. Reported ISS groups varied widely between the years 1986 and 2022. ISS groups reported ranged from 40-75 up to 51-75. Mortality varied between 27 and 100%. The numbers of patients in the highest ISS group ranged between 15 and 1451.

CONCLUSIONS

There are very few critically injured patients reported during the last 48 years. The most critically injured polytrauma patients still have at least a 50% risk of death. There is no consistent inclusion and exclusion criteria for this high-risk cohort. The current approach to reporting is not suitable for monitoring the epidemiology and outcomes of the critically injured polytrauma patients.

Health-related quality of life after severe trauma and available PROMS: an updated review (part I)

Introduction

Throughout the years, a decreasing trend in mortality rate has been demonstrated in patients suffering severe trauma. This increases the relevance of documentation of other outcomes for this population, including patient-reported outcome measures (PROMs), such as health-related quality of life (HRQoL). The aim of this review was to summarize the results of the studies that have been conducted regarding HRQoL in severely injured patients (as defined by the articles’ authors). Also, we present the instruments that are used most frequently to assess HRQoL in patients suffering severe trauma.

Methods

A literature search was conducted in the Cochrane Library, EMBASE, PubMed, and Web of Science for articles published from inception until the 1st of January 2022. Reference lists of included articles were reviewed as well. Studies were considered eligible when a population of patients with major, multiple or severe injury and/or polytrauma was included, well-defined by means of an ISS-threshold, and the outcome of interest was described in terms of (HR)QoL. A narrative design was chosen for this review.

Results

The search strategy identified 1583 articles, which were reduced to 113 after application of the eligibility criteria. In total, nineteen instruments were used to assess HRQoL. The SF-36 was used most frequently, followed by the EQ-5D and SF-12. HRQoL in patients with severe trauma was often compared to normative population norms or pre-injury status, and was found to be reduced in both cases, regardless of the tool used to assess this outcome. Some studies demonstrated higher scoring of the patients over time, suggesting improved HRQoL after considerable time after severe trauma.

Conclusion

HRQoL in severely injured patients is overall reduced, regardless of the instrument used to assess it. The instruments that were used most frequently to assess HRQoL were the SF-36 and EQ-5D. Future research is needed to shed light on the consequences of the reduced HRQoL in this population. We recommend routine assessment and documentation of HRQoL in severely injured patients.

Assessment of patient-reported outcomes after polytrauma - instruments and methods: a systematic review

OBJECTIVES

We (1) collected instruments that assess health-related quality of life (HRQoL), activities of daily living (ADL) and social participation during follow-up after polytrauma, (2) described their use and (3) investigated other relevant patient-reported outcomes (PROs) assessed in the studies.

DESIGN

Systematic Review using the Preferred Reporting Items for Systematic Review and Meta-Analysis guideline.

DATA SOURCES

MEDLINE, Embase, CINAHL, PsycINFO, CENTRAL, as well as the trials registers ClinicalTrials.gov and WHO ICTRP were searched from January 2005 to April 2018.

ELIGIBILITY CRITERIA

All original empirical research published in English or German including PROs of patients aged 18-75 years with an Injury Severity Score≥16 and/or an Abbreviated Injury Scale≥3. Studies with defined injuries or diseases (e.g. low-energy injuries) and some text types (e.g. grey literature and books) were excluded. Systematic reviews and meta-analyses were excluded, but references screened for appropriate studies.

DATA EXTRACTION AND SYNTHESIS

Data extraction, narrative content analysis and a critical appraisal (e.g. UK National Institute for Health and Care Excellence) were performed by two reviewers independently.

RESULTS

The search yielded 3496 hits; 54 publications were included. Predominantly, HRQoL was assessed, with Short Form-36 Health Survey applied most frequently. ADL and (social) participation were rarely assessed. The methods most used were postal surveys and single assessments of PROs, with a follow-up period of one to one and a half years. Other relevant PRO areas reported were function, mental disorders and pain.

CONCLUSIONS

There is a large variation in the assessment of PROs after polytrauma, impairing comparability of outcomes. First efforts to standardise the collection of PROs have been initiated, but require further harmonisation between central players. Additional knowledge on rarely reported PRO areas (e.g. (social) participation, social networks) may lead to their consideration in health services provision.

[Quality of life after multiple trauma]

BACKGROUND

Multiple trauma is an independent injury pattern which, because of its complexity, is responsible for 25 % of the costs for the treatment of all injured patients. Because of the often long-lasting physical impairment and the high incidence of residual permanent handicaps, it is apparent that multiple trauma can lead to a reduction in patient quality of life.

OBJECTIVES

The aim of this study was to give an overview of the known data concerning the change in quality of life for multiple trauma patients. Furthermore, predictors for the reduction of quality of life after multiple trauma will be identified.

MATERIALS AND METHODS

A MedLine search was performed to identify studies dealing with the outcome after multiple trauma.

RESULTS

In addition to functional outcome parameters, the term quality of life has become more important in recent years when it comes to evaluating the outcome following injury. While the mortality after multiple trauma could be significantly reduced over the years, there is no comparable effect on the quality of life. Predictors for a worse quality of life after multiple trauma are female gender, high age, low social status, concomitant head injuries and injury to the lower extremities.

CONCLUSION

The fact that mortality after multiple trauma has decreased but not impairment of the quality of life makes it clear that in addition to the acute medical treatment, a follow-up treatment including not only physiotherapy but also psychotherapy is crucial for multiple trauma patients.

[Sequelae of severe injuries : consequences for trauma rehabilitation]

Consequences of accidents are found not only in physical but also in psychological and social areas. The quality of life of severely injured patients is significantly reduced compared with the normal population even years after the trauma. Subjective experiences of severely injured patients during and after hospitalization have a major impact on the subsequent quality of life. Knowledge of these factors is essential for the planning, organization and implementation of rehabilitation after severe injury. The phase model of rehabilitation after trauma requires early initiation of therapy even during acute treatment as so-called early rehabilitation. After a specialized post-acute rehabilitation additional therapeutic options are often required. Besides pain management the focus lies especially in work-related rehabilitation and psychological support which is also decisive for the success of rehabilitation of accident victims. For severely injured patients it is important to provide sufficient support, e.g. through a case manager which does not end with discharge from the rehabilitation facility. The aim of all efforts is reintegration into the working and social environment and the best possible quality of life.

[Long-term results after multiple trauma with ISS ≥ 25. Outcome and predictors of quality of life]

BACKGROUND

The survival chances of multiple trauma patients have continually improved over the last decades; therefore, it is often not a question of whether a patient survives a severe accident but rather how the patient survives.

METHODS

In a retrospective study 127 patients were questioned regarding quality of life and health and possible influencing factors using the POLO chart an average of 70 months after suffering severe trauma (ISS Ø 35.6).

RESULTS

The quality of life of severely injured patients is significantly reduced compared with the normal population even years after the trauma. In addition to four pretraumatic factors (older age, female gender, low education and previous illnesses) four posttraumatic variables (difficulties with authorities/institutions and unemployment as a consequence of the accident, long duration and subjectively inadequate treatment in hospital) were identified that have a negative impact on long-term quality of life.

CONCLUSIONS

The self-reported quality of life after multiple trauma no longer permanently achieves the original level despite extensive rehabilitation measures. Post-traumatic factors have a greater impact on the long-term quality of life than the injury severity. A long-term care and specialized rehabilitation services are needed to improve outcome further.
