Quality of Life Among Patients Undergoing Decompressive Craniectomy for Traumatic Brain Injury Using Glasgow Outcome Scale Extended and Quality of Life After Brain Injury Scale

Indications and scientific support for supratentorial unilateral decompressive craniectomy for different subgroups of patients: A scoping review

CONTEXT

Even though supratentorial unilateral decompressive craniectomy (DC) has become the gold standard neurosurgical procedure aiming to provide long term relief of intractable intracranial hypertension, its indication has only been validated by high-quality evidence for traumatic brain injury and malignant middle cerebral artery infarction. This scoping review aims to summarize the available evidence regarding DC for these two recognized indications, but also for less validated indications that we may encounter in our daily clinical practice.

MATERIALS AND METHODS

A scoping review was conducted on Medline / Pubmed database from inception to present time looking for articles focused on 7 possible indications for DC indications. Studies' level of evidence was assessed using Oxford University level of evidence scale. Studies' quality was assessed using Newcastle-Ottawa scale for systematic reviews of cohort studies and Cochrane Risk of Bias Tool for randomized controlled trials.

RESULTS

Two randomized trials (level 1b) reported the possible efficacy of unilateral DC and the mitigated efficiency of bifrontal DC in the trauma setting. Five systematic reviews meta-analyses (level 2a) supported DC for severely injured young patients with acute subdural hematoma probably responsible for intraoperative brain swelling, while one randomized controlled trial (level 1b) showed comparable efficacy of DC and craniotomy for ASH with intraoperative neutral brain swelling. Three randomized controlled trials (level 1b) and two meta-analyses (level 1a and 3a) supported DC efficacy for malignant ischemic stroke. One systematic review (level 3a) supported DC efficacy for malignant meningoencephalitis. One systematic review meta-analysis (level 3a) supported DC efficacy for malignant cerebral venous thrombosis. The mitigated results of one randomized trial (level 1b) did not allow to conclude for DC efficacy for intracerebral hemorrhage. One systematic review (level 3a) reported the possible efficacy of primary DC and the mitigated efficacy of secondary DC for aneurysmal subarachnoid hemorrhage. Too weak evidence (level 4) precluded from drawing any conclusion for DC efficacy for intracranial tumors.

CONCLUSION

To date, there is some scientific background to support clinicians in the decision making for DC for selected cases of severe traumatic brain injury, acute subdural hematoma, malignant ischemic stroke, malignant meningoencephalitis, malignant cerebral venous thrombosis, and highly selected cases of aneurysmal subarachnoid hemorrhage.

Health-related quality of life measures in patients undergoing decompressive craniectomy for severe traumatic brain injury: a 6-year follow-up analysis

PURPOSE

We aimed to assess the long-term neurological outcomes and the functionality and QoL in patients undergoing decompressive craniectomy for severe traumatic brain injury, respectively.

MATERIALS AND METHODS

Among the 120 patients who underwent decompressive craniectomy for severe TBI between 2002 and 2007, 101 were included based on the inclusion criteria. Long-term follow-up results (minimum 3 years) were available for 22 patients. The outcomes were assessed using the Glasgow Outcome Scale (GOS) and the functionality and HRQoL were assessed using the Short Form-36 (SF-36) (v2) and Quality of Life After Brain Injury (QoLIBRI) questionnaires.

RESULTS

Among the patients with severe TBI, 62 (61.4%) died and 39 (38.6%) were discharged to either home or a physical therapy facility. Eleven of the thirty-nine patients could not be reached and were excluded from the final analysis. The mean GOS of the remaining 28 patients was 4.14 ± 0.8 after 6.46 ± 1.64 years of follow-up. The HRQoL was assessed in 22 of the 28 patients. The HRQoL scores were lower in patients with TBI than in healthy controls. Furthermore, there was a significant difference in the HRQoL scores in patients with improved GOS scores than in those with unimproved GOS scores.

CONCLUSIONS

Health-related outcome scores could help clinicians understand the requirements of survivors of severe TBI to create a realistic rehabilitation target for them. QoLIBRI served as a good way of communication in these subjects.

Long-term quality of life after decompressive craniectomy

Introduction

This study aims to assess the quality of life (QoL) in patients who have undergone decompressive craniectomy (DC) for any pathology that has caused life-threatening intracranial hypertension. Similarly, it aims to evaluate QoL perceived by caregivers or external informants. In addition to that, the last purpose is to determine which clinical or therapeutic factors could correlate with a better QoL.

Methods

A single-center cross-sectional study was designed. All patients over 18 years old who underwent a supratentorial DC at our department due to intracranial hypertension of any etiology, from January 2015 to December 2021, were retrospectively selected. Patients with incomplete follow-up (under 1 year from the event or those who died) or who declined to participate in the study were excluded. QoL was assessed with SF-36 and CAVIDACE scales. The correlation between clinical and therapeutic variables and SF-36 subscales was studied with Spearman's correlation and the Mann-Whitney U-test.

Results

A total of 55 consecutive patients were recruited: 22 patients had died, three were missed for follow-up, and 15 declined to participate, thus 15 subjects were finally included. The mean follow-up was 47 months (IQR 21.5-67.5). A significant reduction in the "role physical" and "role emotional" subscales of SF-36 was observed compared with the general population. According to caregivers, a significant reduction was assigned to the "physical wellbeing" and "rights" domains. The "physical functioning" score was poorer in women, older patients, those with dominant hemisphere disease, those who required tracheostomy, and those with poor outcomes in the modified Rankin scale. A strong correlation was found between the QoL index at the CAVIDACE scale and the SF-36 subscales "physical functioning" and "role physical".

Conclusion

Most patients and caregivers reported acceptable QoL after DC due to a life-threatening disease. A significant reduction in SF- 36 subscales scores "role limitation due to physical problems" and "role limitation due to emotional problems" was referred by patients. According to caregivers' QoL perception, only 25% of the survey's participants showed low scores in the QoL index of the CAVIDACE scale. Only 26.7% of the patients showed mood disorders.

Can we do better at measuring patient-reported outcomes after cranioplasty? A systematic review

Measuring quality of life (QOL) after cranioplasty is increasingly evident as a necessary component of patient-centered care. For data to be useful in clinical decision-making and approval of new therapies, studies must utilize valid and reliable instruments. Our objective was to critically appraise studies evaluating QOL in adult cranioplasty patients and determine validity and relevance of the patient-reported outcome measures (PROMs) used. Electronic databases of PubMed, Embase, CINAHL, and PsychINFO were used to identify PROMs measuring QOL in adult patients with cranioplasty. The methodological approach, cranioplasty outcomes, and domains measured by the PROMs were extracted and summarized descriptively. A content analysis of the identified PROMs was completed to identify the concepts measured. From 2236 articles identified, 17 articles containing eight QOL PROMs met the inclusion criteria. None of the PROMs was specifically validated or developed for adults undergoing cranioplasty. The QOL domains included physical health, psychological health, social health, and general QOL. These four domains encompassed 216 total items among the PROMs. Appearance was only assessed in two PROMs. To our knowledge, there are currently no validated PROMs that comprehensively measure appearance, facial function, and adverse effects in adults undergoing cranioplasty. There is an urgent need to develop PROMs to measure QOL outcomes rigorously and comprehensively in this patient population to inform clinical care, research, and quality improvement initiatives. Findings from this systematic review will be used to derive an outcome instrument containing important concepts related to QOL in patients who undergo cranioplasty.

The Effectiveness of Dedicated Trauma Operation Theatre and Trauma Intensive Care Unit on the Outcomes of Patients with Traumatic Brain Injury after Emergency Neurosurgery

Background

A dedicated trauma operation theatre (TOT) and a trauma intensive care unit (TICU) within the same block as the emergency department (ED) can facilitate immediate management and surgery of patients suffering from traumatic brain injury (TBI). The present study compared the effectiveness and outcomes of TBI management between the TOT-TICU and general OT (GOT) and neuro-ICU (NICU) setups.

Methods

This was a retrospective cohort study involving 120 patients with TBI who were divided into the GOT-NICU (n = 63) and TOT-TICU (n = 57) groups. Data were obtained from patients' admission and medical records. Demographic data, durations of specific management phases and outcomes of patients were documented.

Results

In the TOT-TICU group, the duration of transportation from ED to OT [15 (standard deviation [SD] = 15) min versus 45 (SD = 15) min; P < 0.001], duration of arrival in OT to incision [50 (SD = 30) versus 70 (SD = 23) min; P = 0.005] and duration of transportation from OT to ICU [40 (SD = 17) versus 48 (SD = 30); P = 0.005] were significantly shorter than those in the GOT-NICU group. However, the duration of mechanical ventilation, duration of ICU stays, Glasgow Outcome Scale (GOS) upon discharge and GOS at 3-month post-discharge were comparable between both groups.

Conclusion

The TOT-TICU setup shortened the duration of transportation from ED to OT, duration of arrival in OT to incision and duration of transportation from OT to ICU compared with the GOT-NICU setup. Hence, the availability of OT and ICU within the trauma block managed to provide immediate management to TBI patients.

The pros and cons of motor, memory, and emotion-related behavioral tests in the mouse traumatic brain injury model

Traumatic brain injury (TBI) is a medical emergency with high morbidity and mortality. Motor, memory, and emotion-related deficits are common symptoms following TBI, yet treatment is very limited. To develop new drugs and find new therapeutic avenues, a wide variety of TBI models have been established to mimic the heterogeneity of TBI. In this regard, along with histologic measures, behavioral functional outcomes provide valuable insight into the underlying neuropathology and guide neurorehabilitation efforts for neuropsychiatric impairment after TBI. Development, characterization, and application of behavioral tests that can assess functional neurologic deficits are essential to the development of translational therapies. This comprehensive review aims to summarize 19 common behavioral tests from three aspects (motor, memory, and emotion-related) that are associated with TBI pathology. Discussion covers the apparatus, the test steps, the evaluation indexes, data collection and analysis, animal performance and applications, advantages and disadvantages as well as precautions to eliminate bias wherever possible. We discussed recent studies on TBI-related preconditioning, biomarkers, and optimized behavioral protocols. The neuropsychologic tests employed in clinics were correlated with those used in mouse TBI models. In summary, this review provides a comprehensive, up-to-date reference for TBI researchers to choose the right neurobehavioral protocol according to the research objectives of their translational investigation.

Decompressive Craniectomy Is Associated With Good Quality of Life Up to 10 Years After Rehabilitation From Traumatic Brain Injury

OBJECTIVES

Traumatic brain injury is the number one cause of death in children and young adults and has become increasingly prevalent in the elderly. Decompressive craniectomy prevents intracranial hypertension but does not clearly improve physical outcome 6 months after traumatic brain injury. However, it has not been analyzed if decompressive craniectomy affects traumatic brain injury patients' quality of life in the long term.

DESIGN

Therefore, we conducted a cross-sectional study assessing health-related quality of life in traumatic brain injury patients with or without decompressive craniectomy up to 10 years after injury.

SETTING

Former critical care patients.

PATIENTS

Chronic traumatic brain injury patients having not (n = 37) or having received (n = 98) decompressive craniectomy during the acute treatment.

MEASUREMENTS AND MAIN RESULTS

Decompressive craniectomy was necessary in all initial traumatic brain injury severity groups. Eight percent more decompressive craniectomy patients reported good health-related quality of life with a Quality of Life after Brain Injury total score greater than or equal to 60 compared with the no decompressive craniectomy patients up to 10 years after traumatic brain injury (p = 0.004). Initially, mild classified traumatic brain injury patients had a median Quality of Life after Brain Injury total score of 83 (decompressive craniectomy) versus 62 (no decompressive craniectomy) (p = 0.028). Health-related quality of life regarding physical status was better in decompressive craniectomy patients (p = 0.025). Decompressive craniectomy showed a trend toward better health-related quality of life in the 61-85-year-old reflected by median Quality of Life after Brain Injury total scores of 62 (no decompressive craniectomy) versus 79 (decompressive craniectomy) (p = 0.06).

CONCLUSIONS

Our results suggest that decompressive craniectomy is associated with good health-related quality of life up to 10 years after traumatic brain injury. Thus, decompressive craniectomy may have an underestimated therapeutic potential after traumatic brain injury.

The patient with severe traumatic brain injury: clinical decision-making: the first 60 min and beyond

PURPOSE OF REVIEW

There is an urgent need to discuss the uncertainties and paradoxes in clinical decision-making after severe traumatic brain injury (s-TBI). This could improve transparency, reduce variability of practice and enhance shared decision-making with proxies.

RECENT FINDINGS

Clinical decision-making on initiation, continuation and discontinuation of medical treatment may encompass substantial consequences as well as lead to presumed patient benefits. Such decisions, unfortunately, often lack transparency and may be controversial in nature. The very process of decision-making is frequently characterized by both a lack of objective criteria and the absence of validated prognostic models that could predict relevant outcome measures, such as long-term quality and satisfaction with life. In practice, while treatment-limiting decisions are often made in patients during the acute phase immediately after s-TBI, other such severely injured TBI patients have been managed with continued aggressive medical care, and surgical or other procedural interventions have been undertaken in the context of pursuing a more favorable patient outcome. Given this spectrum of care offered to identical patient cohorts, there is clearly a need to identify and decrease existing selectivity, and better ascertain the objective criteria helpful towards more consistent decision-making and thereby reduce the impact of subjective valuations of predicted patient outcome.

SUMMARY

Recent efforts by multiple medical groups have contributed to reduce uncertainty and to improve care and outcome along the entire chain of care. Although an unlimited endeavor for sustaining life seems unrealistic, treatment-limiting decisions should not deprive patients of a chance on achieving an outcome they would have considered acceptable.

The Role of Decompressive Craniectomy in Limited Resource Environments

Decompressive craniectomy (DC) is a neurosurgical procedure useful to prevent and manage the impact of high intracranial pressure (ICP) that leads to brain herniation and brain's tissue ischemia. In well-resourced environment this procedure has been proposed as a last tier therapy when ICP is not controlled by medical therapies in the management of different neurosurgical emergencies like traumatic brain injury (TBI), stroke, infectious diseases, hydrocephalus, tumors, etc. The purpose of this narrative review is to discuss the role of DC in areas of low neurosurgical and neurocritical care resources. We performed a literature review with a specific search strategy in web repositories and some local and regional journals from Low and Middle-Income Countries (LMICs). The most common publications include case reports, case series and observational studies describing the benefits of the procedure on different pathologies but with several types of biases due to the absence of robust studies or clinical registries analysis in these kinds of environments.
