Craniotomy for acute subdural hematoma in the elderly: not as bad as you thought

Superiority of craniotomy over supportive care for octogenarians and nonagenarians in operable acute traumatic subdural hematoma

OBJECTIVE

Neurosurgical evacuation in elderly trauma patients is controversial. We analyzed impact of craniotomy for acute subdural hematoma on survival in octogenarians and nonagenarians. Methods The study population included all patients aged ≥ 80 years who presented with acute traumatic SDHs 09/01/15 - 01/01/20, with radiography indicating operative eligibility (i.e. MLS >5 mm and/or overall thickness >10 mm). Of 1054 TBIs aged ≥ 80 years, 104 (9.87%) were surgically indicated. Of these, 35 received craniotomy and 69 received supportive measures due to family/patient wishes or surgeon's professional decision. We analyzed these data using a Poisson regression adjusted for influence of covariates.

RESULTS

Of 35 craniotomies, 21 (60.00%) were deceased at 2 years of follow-up, compared to 48 (69.57%) deceased of 69 non-surgical patients. No significant demographic differences existed between these groups, other than age (craniotomy patients were younger; median age 84 vs 86; p < 0.001). In outcomes, the craniotomy cohort survived longer and in higher proportions (p = 0.028; Gehan-Breslow-Wilcoxon). When adjusting for covariates, this effect became more pronounced: craniotomy patients died at 41.1% the rate of non-surgical ones. Of all the covariates, only initial GCS significantly impacted the protective effect of craniotomy. In a logarithmic relationship, each point on initial GCS was associated with less benefit from surgery. We also found that patients with GCS< 3 were overall less likely to benefit from surgery. Our conclusions are limited by the impact of patient/surgeon choice on whether or not to operate. It is possible healthier subjects elected for craniotomies. We have attempted to correct for this by including comorbidities as covariates in our regression analyses.

CONCLUSIONS

Our results indicate a surgical benefit for this elderly cohort, consistent with prior findings of benefit in the setting of severe traumatic aSDH. Patients with worse neurologic impairment, i.e. low GCS, had the greatest survival benefit from surgical intervention.

Risk Factors Contributing to Higher Mortality Rates in Elderly Patients with Acute Traumatic Subdural Hematoma Sustained in a Fall: A Cross-Sectional Analysis Using Registered Trauma Data

Background: We aimed to explore the risk factors that contribute to the mortality of elderly trauma patients with acute subdural hematoma (SDH) resulting from a fall. Mortality rates of the elderly were compared to those of young adults. Methods: A total of 444 patients with acute traumatic subdural hematoma resulting from a fall, admitted to a level I trauma center from 1 January 2009 to 31 December 2016 were enrolled in this study. Patients were categorized into two groups: elderly patients (n = 279) and young adults (n = 165). The primary outcome of this study was patient mortality in hospital. The adjusted odds ratio (AOR) with 95% confidence interval (CI) for mortality was calculated according to gender and pre-existing comorbidities. Univariate and multivariate logistic regression analyses were performed to identify factors related to mortality in the elderly. Results: The odds ratio for mortality caused by falls in the elderly patients was four-fold higher than in the young adults, after adjusting for gender and pre-existing comorbidities. In addition, the presence of pre-existing coronary artery disease (OR 3.2, 95% CI 1.09–9.69, p = 0.035), end-stage renal disease (OR 4.6, 95% CI 1.48–14.13, p = 0.008), hematoma volume (OR 1.2, 95% CI 1.11–1.36, p < 0.001), injury severity score (OR 1.3, 95% CI 1.23–1.46, p < 0.001), and coagulopathy (OR 4.0, 95% CI 1.47–11.05, p = 0.007) were significant independent risk factors for mortality in patients with acute traumatic SDH resulting from a fall. Conclusions: In this study, we identified that pre-existing CAD, ESRD, hematoma volume, ISS, and coagulopathy were significant independent risk factors for mortality in patients with acute traumatic SDH. These results suggest that death following acute SDH is influenced both by the extent of neurological damage and the overall health of the patient at the time of injury.

Geriatric Traumatic Brain Injury: Epidemiology, Outcomes, Knowledge Gaps, and Future Directions

This review of the literature on traumatic brain injury (TBI) in older adults focuses on incident TBI sustained in older adulthood ("geriatric TBI") rather than on the separate, but related, topic of older adults with a history of earlier-life TBI. We describe the epidemiology of geriatric TBI, the impact of comorbidities and pre-injury function on TBI risk and outcomes, diagnostic testing, management issues, outcomes, and critical directions for future research. The highest incidence of TBI-related emergency department visits, hospitalizations, and deaths occur in older adults. Higher morbidity and mortality rates among older versus younger individuals with TBI may contribute to an assumption of futility about aggressive management of geriatric TBI. However, many older adults with TBI respond well to aggressive management and rehabilitation, suggesting that chronological age and TBI severity alone are inadequate prognostic markers. Yet there are few geriatric-specific TBI guidelines to assist with complex management decisions, and TBI prognostic models do not perform optimally in this population. Major barriers in management of geriatric TBI include under-representation of older adults in TBI research, lack of systematic measurement of pre-injury health that may be a better predictor of outcome and response to treatment than age and TBI severity alone, and lack of geriatric-specific TBI common data elements (CDEs). This review highlights the urgent need to develop more age-inclusive TBI research protocols, geriatric TBI CDEs, geriatric TBI prognostic models, and evidence-based geriatric TBI consensus management guidelines aimed at improving short- and long-term outcomes for the large and growing geriatric TBI population.

Outcomes of chronic subdural hematoma drainage in nonagenarians and centenarians: a multicenter study

OBJECTIVE

Chronic subdural hemorrhage (SDH) or hematoma is a condition that affects elderly individuals. With advances in medical care, the number of nonagenarians and centenarians will increase. However, surgical treatments in this age group are associated with high rates of morbidity and mortality. Because no data are available on the rates of survival among elderly patients with chronic SDHs who undergo surgical drainage or receive only conservative care, the goal of this study was to determine survival rates in patients 90 years of age or older with symptomatic chronic SDHs.

METHODS

The authors conducted a retrospective analysis of patient data that were collected at 3 hospitals over a 13-year period (from January 2001 to June 2013). The data from patients 90 years or older with symptomatic chronic SDHs and who were offered surgical treatment were included in the analysis. Patients who underwent surgical treatment were included in the surgical group and patients who declined an operation were included in the conservative care group. The patients' Charlson Comorbidity Index score, Karnofsky Performance Scale score, dates of death, presenting symptoms, Glasgow Coma Scale score, length of stay in the hospital, discharge location, side of the SDH, and neurological improvements at 30-day and 6-month follow-ups were recorded. Data were statistically analyzed with Fisher exact test, Kaplan-Meier curves, and logistic regression.

RESULTS

In total, 101 patients met the inclusion criteria of this study; 70 of these patients underwent surgical drainage, and 31 received conservative care. Patients in the surgical group had statistically significantly (p < 0.001) higher survival at both the 30-day and 6-month follow-ups, with 92.9% and 81.4% of the patients in this group surviving for at least 30 days and 6 months, respectively, versus 58.1% and 41.9%, respectively, in the conservative care group. Moreover, the mean overall length of survival of 34.4 ± 28.7 months was longer in the surgical group than it was in the conservative care group (11.3 ± 16.6 months). Overall, 95.7% of patients in the surgical group exhibited an improvement in neurological status after the SDH drainage, whereas none of the patients in the conservative care group showed any neurological improvement during their hospital stay. The surgical complication rate was 11.4%, and the overall rate of chronic SDH recurrence after surgery was 12.9%.

CONCLUSIONS

Surgical drainage of chronic SDHs in nonagenarians and centenarians is associated with lower incidence of inpatient death and higher 30-day and 6-month survival rates.
