RESUMO
BACKGROUND: Chronic subdural haematoma is a common surgically treated intracranial emergency. Burr-hole drainage surgery, to evacuate chronic subdural haematoma, involves three elements: creation of a burr hole for access, irrigation of the subdural space, and insertion of a subdural drain. Although the subdural drain has been established as beneficial, the therapeutic effect of subdural irrigation has not been addressed. METHODS: The FINISH trial was an investigator-initiated, pragmatic, multicentre, nationwide, randomised, controlled, parallel-group, non-inferiority trial in five neurosurgical units in Finland that enrolled adults aged 18 years or older with a chronic subdural haematoma requiring burr-hole drainage. Patients were randomly assigned (1:1) by computer-generated block randomisation with block sizes of four, six, or eight, stratified by site, to burr-hole drainage either with or without subdural irrigation. All patients and staff were masked to treatment assignment apart from the neurosurgeon and operating room staff. A burr hole was drilled at the site of maximum haematoma thickness in both groups, and the subdural space was either irrigated or not irrigated before inserting a subdural drain, which remained in place for 48 h. Reoperations, functional outcome, mortality, and adverse events were recorded for 6 months after surgery. The primary outcome was the reoperation rate within 6 months. The non-inferiority margin was set at 7·5%. Key secondary outcomes that were also required to conclude non-inferiority were the proportion of participants with unfavourable functional outcomes (ie, modified Rankin Scale score of 4-6, where 0 indicates no symptoms and 6 indicates death) and mortality rate at 6 months. The primary and key secondary analyses were done in both the intention-to-treat and per-protocol populations. The trial was registered with ClinicalTrials.gov (NCT04203550) and is completed. FINDINGS: From Jan 1, 2020, to Aug 17, 2022, we assessed 1644 patients for eligibility and 589 (36%) patients were randomly assigned to a treatment group and treated (294 assigned to drainage with irrigation and 295 assigned to drainage without irrigation; 165 [28%] women and 424 [72%] men). The 6-month follow-up period extended until Feb 14, 2023. In the intention-to-treat analysis, 54 (18·3%) of 295 participants required reoperation in the group assigned to receive no irrigation versus 37 (12·6%) of 294 in the group assigned to receive irrigation (difference of 6·0 percentage points, 95% CI 0·2-11·7; p=0·30; adjusted for study site). There were no significant between-group differences in the proportion of people with modified Rankin Scale score of 4-6 (37 [13·1%] of 283 in the no-irrigation group vs 36 [12·6%] of 285 in the irrigation group; p=0·89) or mortality rate (18 [6·1%] of 295 in the no-irrigation group vs 21 [7·1%] of 294 in the irrigation group; p=0·58). The findings of the primary intention-to-treat analysis were not materially altered in the per-protocol analysis. There were no significant between-group differences in the number of adverse events, and the most frequent severe adverse events were systemic infections (26 [8·8%] of 295 participants who did not receive irrigation vs 22 [7·5%] of 294 participants who received irrigation), intracranial haemorrhage (13 [4·4%] vs seven [2·4%]), and epileptic seizures (five [1·7%] vs nine [3·1%]). INTERPRETATION: We could not conclude non-inferiority of burr-hole drainage without irrigation. The reoperation rate was 6·0 percentage points higher after burr-hole drainage without subdural irrigation than with subdural irrigation. Considering that there were no differences in functional outcome or mortality between the groups, the trial favours the use of subdural irrigation.

BACKGROUND: Controversy exists whether blood pressure augmentation therapy benefits patients suffering from spinal cord injury (SCI). This retrospective comparative study was designed to assess the impact of two different mean arterial pressure (MAP) targets (85-90 mmHg vs. 65-85 mmHg) on neurological recovery after traumatic cervical SCI. METHODS: Fifty-one adult patients with traumatic cervical SCI were retrospectively divided into two groups according to their intensive care unit (ICU) MAP targets: 85-90 mmHg (higher MAP group, n = 32) and 65-85 mmHg (lower MAP group, n = 19). Invasive MAP measurements were stored as 2-min median values for 3-7 days. The severity of SCI (AIS grade and neurological level) was evaluated upon ICU stay and during rehabilitation. Neurological recovery was correlated with individual mean MAP values and with the proportion of MAP values ≥85 mmHg upon the first 3 days (3d-MAP%≥85 ). RESULTS: The initial AIS grades were A 29.4%, B 17.6%, C 31.4%, and D 21.6%. AIS grade improved in 24 patients (47.1%). During ICU care, 82.0% and 36.8% of the measured MAP values reached ≥85 mmHg in the higher and the lower MAP groups, respectively (p < .001). The medians of individual mean MAP values were different between the groups (90.2 mmHg vs. 81.4 mmHg, p < .001). Similarly, 3d-MAP%≥85 was higher in the higher MAP group (85.6% vs. 50.0%, p < .001). However, neurological recovery was not different between the groups, nor did it correlate with individual mean MAP values or 3d-MAP%≥85 . CONCLUSION: The currently recommended MAP target of 85-90 mmHg was not associated with improved outcomes compared to a lower target in patients with traumatic cervical SCI in this cohort.

PURPOSE: The objective was to determine the incidence of surgically treated chronic subdural hematoma (cSDH) within six months after head trauma in a consecutive series of head injury patients with a normal initial computed tomography (CT). METHODS: A total of 1941 adult patients with head injuries who underwent head CT within 48 h after injury and were treated at the Tampere University Hospital's emergency department were retrospectively evaluated from medical records (median age = 59 years, IQR = 39-79 years, males = 58%, patients using antithrombotic medication = 26%). Patients with no signs of acute traumatic intracranial pathology or any type of subdural collection on initial head CT were regarded as CT negative (n = 1573, 81%). RESULTS: Two (n = 2) of the 1573 CT negative patients received surgical treatment for cSDH. Consequently, the incidence of surgically treated cSDH after a normal initial head CT during a six-month follow-up was 0.13%. Both patients sustained mild traumatic brain injuries initially. One of the two patients was on antithrombotic medication (warfarin) at the time of trauma, hence incidence of surgically treated cSDH among patients with antithrombotic medication in CT negative patients (n = 376, 23.9%) was 0.27%. Additionally, within CT negative patients, one subdural hygroma was operated shortly after trauma. CONCLUSION: The extremely low incidence of surgically treated cSDH after a normal initial head CT, even in patients on antithrombotic medication, supports the notion that routine follow-up imaging after an initial normal head CT is not indicated to exclude the development of cSDH. Additionally, our findings support the concept of cSDH not being a purely head trauma-related disease.

BACKGROUND: Most of moderate and severe pTBIs are managed conservatively, but in some cases neurosurgical interventions are needed. The incidence rates of acute pTBI neurosurgery vary considerably between countries and operation types. Our goal was to assess the incidence of acute pTBI neurosurgery in Finland. METHODS: We conducted a retrospective Finnish register-based cohort study from 1998 to 2018. We included all patients that were 0 to 17 years of age at the time of the TBI. The incidence rates of patients with pTBI undergoing neurosurgery and the rates for specific operation types were calculated per 100,000 person-years. We compared the annual incidences with incidence rate ratios (IRR) with 95% confidence intervals (CI). We stratified patients to three age categories: (i) 0 to 3 years of age, (ii) 4 to 12 years of age, and (iii) 13 to 17 years of age. RESULTS: The total number of neurosurgeries for acute pTBI during the study period was 386, and the cumulative incidence was 1.67 operations per 100,000 person-years. The cumulative incidence during the 21-year follow-up was highest at the age of 16 (IRR 4.78, CI 3.68 to 6.11). Boys had a 2.42-time higher cumulative incidence (IRR 2.35, CI 1.27 to 3.99) than girls (IRR 0.97, CI 0.35 to 2.20). The most common neurosurgery was an evacuation of an intracranial hemorrhage (n = 171; 44.3%). CONCLUSION: The incidence of neurosurgeries for pTBIs has been stable from 1998 to 2018. The incidence was highest at the age of 16, and boys had higher incidence than girls.

BACKGROUND: Recent studies from Finland have highlighted an increase in the incidence of traumatic brain injuries (TBI) in older age groups and high overall mortality. We performed a comprehensive study on the changing epidemiology of TBI focusing on the acute events in the Finnish working-age population. METHODS: Nationwide databases were searched for all emergency ward admissions with a TBI diagnosis for persons of 16-69 years of age during 2004-2018. RESULTS: In the Finnish working-age population, there were 52,487,099 person-years, 38,810 TBI-related hospital admissions, 4664 acute neurosurgical operations (ANO), and 2247 cases of in-hospital mortality (IHM). The TBI-related hospital admission incidence was 94/100,000 person-years in men, 44/100,000 in women, and 69/100,000 overall. The incidence rate of admissions increased in women, while in men and overall, the rate decreased. The incidence rate increased in the group of 60-69 years in both genders. Lowest incidence rates were observed in the age group of 30-39 years. Occurrence risk for TBI admission was higher in men in all age groups. Trends of ANOs decreased overall, while decompressive craniectomy was the only operation type in which a rise in incidence was found. Evacuation of acute subdural hematoma was the most common ANO. Mean length of stay and IHM rate halved during the study years. CONCLUSIONS: In Finland, the epidemiology of acute working-aged TBI has significantly changed. The rates of admission incidences, ANOs, and IHM nowadays represent the lower end of the range of these acute events reported in the western world.

BACKGROUND: Post-traumatic hydrocephalus (PTH) is a well-known complication of head injury. The percentage of patients experiencing PTH in trauma cohorts (0.7-51.4%) varies greatly in the prior literature depending on the study population and applied diagnostic criteria. The objective was to determine the incidence of surgically treated PTH in a consecutive series of patients undergoing acute head computed tomography (CT) following injury. METHODS: All patients (N = 2908) with head injuries who underwent head CT and were treated at the Tampere University Hospital's Emergency Department (August 2010-July 2012) were retrospectively evaluated from patient medical records. This study focused on adults (18 years or older) who were residents of the Pirkanmaa region at the time of injury and were clinically evaluated and scanned with head CT at the Tampere University Hospital's emergency department within 48 h after injury (n = 1941). A thorough review of records for neurological signs and symptoms of hydrocephalus was conducted for all patients having a radiological suspicion of hydrocephalus. The diagnosis of PTH was based on clinical and radiological signs of the condition within 6 months following injury. The main outcome was surgical treatment for PTH. Clinical evidence of shunt responsiveness was required to confirm the diagnosis of PTH. RESULTS: The incidence of surgically treated PTH was 0.15% (n = 3). Incidence was 0.08% among patients with mild traumatic brain injury (TBI) and 1.1% among those with moderate to severe TBI. All the patients who developed PTH underwent neurosurgery during the initial hospitalization due to the head injury. The incidence of PTH among patients who underwent neurosurgery for acute traumatic intracranial lesions was 2.7%. CONCLUSION: The overall incidence of surgically treated PTH was extremely low (0.15%) in our cohort. Analyses of risk factors and the evaluation of temporal profiles could not be undertaken due to the extremely small number of cases.

BACKGROUND: A number of patients who sustain a traumatic brain injury (TBI) require surgical intervention due to acute intracranial bleeding. The aim of this retrospective study was to assess the national trends of acute craniotomies following TBI in the Finnish adult population. METHODS: The data were collected retrospectively from the Finnish Care Register for Health Care (1997-2018). The study cohort covered all first-time registered craniotomies following TBI in patients aged 18 years or older. A total of 7627 patients (median age = 59 years, men = 72%) were identified. RESULTS: The total annual incidence of acute trauma craniotomies decreased by 33%, from 8.6/100,000 in 1997 to 5.7/100,000 in 2018. The decrease was seen in both genders and all age groups, as well as all operation subgroups (subdural hematoma, SDH; epidural hematoma, EDH; intracerebral hematoma, ICH). The greatest incidence rate of 15.4/100,000 was found in patients 70 years or older requiring an acute trauma craniotomy. The majority of surgeries were due to an acute SDH and the patients were more often men. The difference between genders decreased with age (18-39 years = 84% men, 40-69 = 78% men, 70 + years = 55% men). The median age of the patients increased from 58 to 65 years during the 22-year study period. CONCLUSIONS: The number of trauma craniotomies is gradually decreasing; nonetheless, the incidence of TBI-related craniotomies remains high among geriatric patients. Further studies are needed to determine the indications and derive evidence-based guidelines for the neurosurgical care of older adults with TBIs to meet the challenges of the growing elderly population.

BACKGROUND: Anemia might contribute to the development of secondary injury in patients with acute traumatic brain injury (TBI). Potential determinants of anemia are still poorly acknowledged, and reported incidence of declined hemoglobin concentration varies widely between different studies. The aim of this study was to investigate the incidence of severe anemia among patients with moderate to severe TBI and to evaluate patient- and trauma-related factors that might be associated with the development of anemia. METHODS: This retrospective cohort study involved all adult patients admitted to Tampere University Hospital's emergency department for moderate to severe TBI (August 2010 to July 2012). Detailed information on patient demographics and trauma characteristics were obtained, including data on posttraumatic care, data on neurosurgical procedures, and all measured in-hospital hemoglobin values. Severe anemia was defined as a hemoglobin level less than 100 g/L. Both univariate and multivariable analyses were performed, and hemoglobin trajectories were created. RESULTS: The study included 145 patients with moderate to severe TBI (male 83.4%, mean age 55.0 years). Severe anemia, with a hemoglobin level less than 100 g/L, was detected in 66 patients (45.5%) and developed during the first 48 h after the trauma. In the univariate analysis, anemia was more common among women (odds ratio [OR] 2.84; 95% confidence interval [CI] 1.13-7.15), patients with antithrombotic medication prior to trauma (OR 3.33; 95% CI 1.34-8.27), patients with cardiovascular comorbidities (OR 3.12; 95% CI 1.56-6.25), patients with diabetes (OR 4.56; 95% CI 1.69-12.32), patients with extracranial injuries (OR 3.14; 95% CI 1.69-12.32), and patients with midline shift on primary head computed tomography (OR 2.03; 95% CI 1.03-4.01). In the multivariable analysis, midline shift and extracranial traumas were associated with the development of severe anemia (OR 2.26 [95% CI 1.05-4.48] and OR 4.71 [95% CI 1.74-12.73], respectively). CONCLUSIONS: Severe anemia is common after acute moderate to severe TBI, developing during the first 48 h after the trauma. Possible anemia-associated factors include extracranial traumas and midline shift on initial head computed tomography.

INTRODUCTION: There is minimal existing available information on nationwide seasonal peaks in traumatic brain injuries (TBIs). This lack of information is an impediment to the effective development of prevention programs, societal policies, and hinders the resourcing of medical emergency services. Our current aim is to study nationwide population-based high-risk periods TBI over a 15-year study period in Finland. METHODS: Nationwide databases were searched for all admissions with a TBI diagnosis and later for deaths of persons ≥16 years of age during 2004-2018. The search included all hospitals that provide acute TBI care in Finland. RESULTS: The study period included 69,231 TBI-related hospital admissions (men = 62%). We found that for men, the highest rate of TBIs occurred on Saturdays, whereas women experience the highest rate of TBIs on Mondays. The highest rate of TBIs in men occurred in July, while women experienced the highest rate of TBIs in January. TBI-related hospital admissions (incidence risk ratio [IRR] 1.090, 95% CI 1.07-1.11, p < 0.0001) and mortality within 30 days after TBI (hazard ratio [HR] 1.057, 95% CI 1.001-1.116, p = 0.0455) were more common on public holidays and weekends than on weekdays. There was an increasing trend in the proportion of TBI-related hospital admissions occurring on public holidays and weekends from 2004 (31.5%) to 2018 (33.4%) (p = 0.0007). In summer months, TBI-related hospital admissions (IRR 1.10, 95% CI 1.08-1.12, p < 0.0001) and 30-day mortality (HR 1.069, 95% CI 1.010-1.131, p = 0.0211) were more common than in other months. TBIs occurred more often in younger and healthier individuals on these index days and times. In terms of specific public holidays, the TBI risk was overall higher on New Year's Eves and Days (IRR 1.40, 95% CI 1.25-1.58, p < 0.0001) and Midsummer's Eves and Days (IRR 1.36, 95% CI 1.20-1.54, p < 0.0001), compared to nonworking days. This finding was significant in both genders. CONCLUSIONS: TBI-related hospital admissions and mortality were more common on public holidays, weekends, and in summer months in Finland. People who sustained TBIs on these days were on average younger and healthier. The occurrence of TBIs on public holidays and weekends is increasing at an alarming rate.

PURPOSE OF REVIEW: To provide an overview on recent advances in the field of assessment and monitoring of patients with severe traumatic brain injury (sTBI) in neurocritical care from a neurosurgical point of view. RECENT FINDINGS: In high-income countries, monitoring of patients with sTBI heavily relies on multimodal neurocritical parameters, nonetheless clinical assessment still has a solid role in decision-making. There are guidelines and consensus-based treatment algorithms that can be employed in both absence and presence of multimodal monitoring in the management of patients with sTBI. Additionally, novel dynamic monitoring options and machine learning-based prognostic models are introduced. Currently, the acute management and treatment of secondary injury/insults is focused on dealing with the objective evident pathology. An ongoing paradigm shift is emerging towards more proactive treatment of neuroworsening as soon as premonitory signs of deterioration are detected. SUMMARY: Based on the current evidence, serial clinical assessment, neuroimaging, intracranial and cerebral perfusion pressure and brain tissue oxygen monitoring are key components of sTBI care. Clinical assessment has a crucial role in identifying the crashing patient with sTBI, especially from a neurosurgical standpoint. Multimodal monitoring and clinical assessment should be seen as complementary evaluation methods that support one another.

BACKGROUND: Diffusion tensor imaging (DTI) is a magnetic resonance imaging (MRI) technique used for evaluating changes in the white matter in brain parenchyma. The reliability of quantitative DTI analysis is influenced by several factors, such as the imaging protocol, pre-processing and post-processing methods, and selected diffusion parameters. The region-of-interest (ROI) method is most widely used of the post-processing methods because it is found in commercial software. The focus of our research was to study the reliability of the freehand ROI method using various intra- and inter-observer analyses. METHODS: This study included 40 neurologically healthy participants who underwent diffusion MRI of the brain with a 3 T scanner. The measurements were performed at nine different anatomical locations using a freehand ROI method. The data extracted from the ROIs included the regional mean values, intra- and inter-observer variability and reliability. The used DTI parameters were fractional anisotropy (FA), the apparent diffusion coefficient (ADC), and axial (AD) and radial (RD) diffusivity. RESULTS: The average intra-class correlation coefficient (ICC) of the intra-observer was found to be 0.9 (excellent). The single ICC results were excellent (> 0.8) or adequate (> 0.69) in eight out of the nine regions in terms of FA and ADC. The most reliable results were found in the frontobasal regions. Significant differences between age groups were also found in the frontobasal regions. Specifically, the FA and AD values were significantly higher and the RD values lower in the youngest age group (18-30 years) compared to the other age groups. CONCLUSIONS: The quantitative freehand ROI method can be considered highly reliable for the average ICC and mostly adequate for the single ICC. The freehand method is suitable for research work with a well-experienced observer. Measurements should be performed at least twice in the same region to ensure that the results are sufficiently reliable. In our study, reliability was slightly undermined by artifacts in some regions such as the cerebral peduncle and centrum semiovale. From a clinical point of view, the results are most reliable in adults under the age of 30, when age-related changes in brain white matter have not yet occurred.

STUDY DESIGN: Prospective cohort study. OBJECTIVES: To determine the incidence and evaluate the characteristics of newly injured patients admitted to two spinal cord injury (SCI) centers during a 4-year period. SETTING: Oulu and Tampere University Hospital, Finland. METHODS: A dedicated multidisciplinary team evaluated all of the patients with new traumatic SCI (TSCI). The data were recorded according to the International Spinal Cord Injury Core Data Sets. RESULTS: In a 4-year period, 346 new patients with TSCI were admitted to the study centers. In the Oulu and Tampere University Hospitals' catchment areas, the mean annual incidence of TSCI was 36.6 per million. The leading causes of injury were low-level falls (36.2%), high-level falls (25.5%), and transport-related accidents (19.2%). In the patients >60 years, 72.6% were injured by falling and the proportion of low-level falls was 49.7%. In the patients ≤60 years old, 47.4% were alcohol-related. The proportion of cervical injuries in the patients >60 years was 77.1%, while in the patients ≤60 years the proportion was 59.6%. The incidence of TSCI was higher during the Summer and Autumn months. CONCLUSION: The mean annual incidence of TSCI was 36.6 per million corresponding to 200 new annual cases in Finland. Incomplete tetraplegia due to falling among elderly was overrepresented in the study population. Alcohol-consumption preceded injury in nearly half of the cases in the younger population. The prevention should focus on alcohol-related injuries and falls in the elderly.

OBJECTIVE: This study examined the prevalence of preexisting conditions that could affect premorbid brain health, cognition, and functional independence among older adults with mild traumatic brain injury (MTBI), and the relationship between preexisting conditions, injury characteristics, and emergency department (ED) discharge location (home versus continued care). METHODS: Older adults (N = 1,427; 55-104 years-old; 47.4% men) who underwent head computed tomography (CT) after acute head trauma were recruited from the ED. Researchers documented preexisting medical conditions retrospectively from hospital records. RESULTS: Multiple preexisting conditions increased in frequency with greater age, including circulatory and nervous system diseases and preexisting abnormalities on head CT. Psychiatric and substance use disorders (SUDs) decreased in frequency with greater age. Among participants with uncomplicated MTBI and GCS = 15, preexisting nervous system diseases and preexisting CT abnormalities were associated with higher odds of continued care for all participants, whereas psychiatric disorders and SUDs were only associated with higher odds of continued care among participants <70 years-old. Preexisting circulatory diseases, loss of consciousness, and amnesia were unassociated with discharge location. CONCLUSIONS: Preexisting medical conditions that could affect brain and cognitive health occur commonly among older adults who sustain MTBIs. These conditions can confound research examining post-injury outcomes within this age group.

OBJECTIVES: Previous older adult studies have examined outcome from moderate-to-severe traumatic brain injury (TBI), but fewer have focused on the effects of milder brain injuries. This study examined age-related differences in symptom reporting and whether symptoms are differentially related to functional outcome based on age. MATERIALS & METHODS: Patients presenting with a head injury at the Tampere University Hospital emergency department (N = 325, aged 18-100) were evaluated at 1 week post injury on the Modified Rankin Scale and Rivermead Post Concussion Symptoms Questionnaire (RPQ). RESULTS: A quarter of participants had missing RPQ data, with missingness associated with greater age and strongly associated with pre-existing functional impairment, dementia, and/or neurological conditions. Among participants with complete data, participants <65 years old endorsed headaches, noise/light sensitivity, irritability, and frustration/impatience at a greater frequency than participants ≥65 years old. However, no differences were found in the number of symptoms endorsed or the total symptom severity score. The correlations between the severity of symptoms and change in function were similar between the two age groups. CONCLUSIONS: Older adults tended to report fewer symptoms, but symptoms had a roughly equivalent relationship with declines in functioning across age groups. A large percentage of older adults in this study had pre-injury dementia or neurological disease that contributed to missing data on the 1-week outcome measures. The results provide insight into the impact of mild spectrum TBI on older adults compared to younger patients.

BACKGROUND: we investigated trends of traumatic brain injury (TBI)-related hospitalisations, deaths, acute neurosurgical operations (ANO), and lengths of hospital stay (LOS) in patients aged ≥70 years in Finland using a population-based cohort. METHODS: nationwide databases were searched for all admissions with a TBI diagnosis as well as later deaths for persons ≥70 years of age during 2004-2014. RESULTS: the study period included 20,259 TBI-related hospitalisations (mean age = 80.7 years, men = 48.9%). The incidence of TBI-related hospitalisations was 283/100,000 person-years with an estimated overall annual increase of 2.9% (95% CI: 0.4-5.9%). There was an annual decrease of 2.2% in in-hospital mortality (IHM) in men (95% CI: 0.1-4.3%), with no change in women or overall. There was an annual decrease of 1.1% in odds for ANOs among hospitalised overall (95% CI: 0.1-2.1%) and of 1.4% in men (95% CI: 0.0-2.7%), while no change was observed in women. LOS decreased annually by 2.5% (95% CI: 2.1-2.9%). The incidence of TBI-related deaths was 70/100,000 person-years with an estimated annual increase of 1.6% in women (95% CI: 0.2-2.9%), but no change in men or overall. Mean ages of TBI-related admissions and deaths increased (P < 0.001). INTERPRETATION: the incidence rate of geriatric TBI-related hospitalisations increased, especially in women, but LOS and the rate of ANOs among hospitalised decreased. The overall TBI-related mortality remained stable, and IHM decreased in men, while in women, the overall mortality increased and IHM remained stable. However, the overall incidence rates of TBI-related hospitalisations and deaths and the number of cases of IHM were still higher in men.

OBJECTIVE: To assess possible long-term excess mortality and causes of death of patients with chronic subdural hematoma (CSDH). METHODS: A retrospective study (1990-2015) of adult patients (n = 1133, median age = 76 years old, men = 65%) with CSDH identified by ICD-codes and verified by medical records. All patients were followed until death or the end of 2017. Cumulative relative survival ratios and relative excess risks of death (RER) were estimated by comparing patients' mortality with that in the entire regional matched population. The causes of death were compared with a separate reference group formed by randomly choosing sex, age, and calendar time matched controls (4 controls per each CSDH patient). RESULTS: The median follow-up time was 4.8 years (range = 0-27 years), and 710 (63%) of the patients died (median age at death = 84 years old). The cumulative excess mortality was 1 year = 9%, 5 years = 18%, 10 years = 27%, 15 years = 37%, and 20 years = 48%. A subgroup of CSDH patients (n = 206) with no comorbidity had no excess mortality. Excess mortality was related to poor modified Rankin score at admission (RER = 4.93) and at discharge (RER = 8.31), alcohol abuse (RER = 4.47), warfarin (RER = 2.94), age ≥ 80 years old (RER = 1.83), non-operative treatment (RER = 1.56), and non-traumatic etiology (RER = 1.69). Hematoma characteristics or recurrence were unrelated to excess mortality. Dementia was the most common cause of death among the CSDH patients (21%) and the third most common cause in the reference group (15%, p < 0.001). CONCLUSIONS: Patients with CSDH have continuous excess mortality up to 20 years after diagnosis. Patient-related characteristics have a strong association with excess mortality, whereas specific CSDH-related findings do not. CSDH patients have an increased risk for dementia-related mortality.

OBJECTIVE: To examine the population-based incidence, complications, and total, direct hospital costs of chronic subdural hematoma (CSDH) treatment in a neurosurgical clinic during a 26-year period. The aim was also to estimate the necessity of planned postoperative follow-up computed tomography (CT). METHODS: A retrospective cohort (1990-2015) of adult patients living in Pirkanmaa, Finland, with a CSDH was identified using ICD codes and verified by medical records (n = 1148, median age = 76 years, men = 65%). Data collection was performed from medical records. To estimate the total, direct hospital costs, all costs from hospital admission until the last neurosurgical follow-up visit were calculated. All patients were followed until death or the end of 2017. The annual number of inhabitants in the Pirkanmaa Region was obtained from the Statistics Finland (Helsinki, Finland). RESULTS: The incidence of CSDH among the population 80 years or older has increased among both operatively (from 36.6 to 91/100,000/year) and non-operatively (from 4.7 to 36.9/100,000/year) treated cases. Eighty-five percent (n = 978) underwent surgery. Routine 4-6 weeks' postoperative follow-up CT increased the number of re-operations by 18% (n = 49). Most of the re-operations (92%) took place within 2 months from the primary operation. Patients undergoing re-operations suffered more often from seizures (10%, n = 28 vs 3.9%, n = 27; p < 0.001), empyema (4.3%, n = 12 vs 1.1%, n = 8; p = 0.002), and pneumonia (4.7%, n = 13 vs 1.4%, n = 12; p = 0.008) compared with patients with no recurrence. The treatment cost for recurrent CSDHs was 132% higher than the treatment cost of non-recurrent CSDHs, most likely because of longer hospital stay for re-admissions and more frequent outpatient follow-up with CT. The oldest group of patients, 80 years or older, was not more expensive than the others, nor did this group have more frequent complications, besides pneumonia. CONCLUSIONS: Based on our population-based study, the number of CSDH patients has increased markedly during the study period (1990-2015). Reducing recurrences is crucial for reducing both complications and costs. Greater age was not associated with greater hospital costs related to CSDH. A 2-month follow-up period after CSDH seems sufficient for most, and CT controls are advocated only for symptomatic patients.

OBJECTIVE: There is enormous research and clinical interest in blood-based biomarkers of mild traumatic brain injury (MTBI) sustained in sports, daily life, or military service. We examined the reliability of a commercially available assay for S100B used on the same samples by two different laboratories separated by 2 years in time. METHODS AND PROCEDURES: A cohort of 163 adult patients (head CT-scanned, n = 110) with mild head injury were enrolled from the emergency department (ED). All had Glasgow Coma Scale scores of 14 or 15 in the ED (94.4% = 15). The mean time between injury and venous blood sampling was 2.9 h (SD = 1.4; Range = 0.5-6.0 h). Serum S100B was measured at two independent centers using the same high throughput clinical assay (Elecsys S100B®; Roche Diagnostics). RESULTS: The Spearman correlation between the two assays in the total sample (N = 163) was r = 0.93. A Wilcoxson Signed Ranks test indicated that the median scores for the values differed (Z = 2,082, p < .001, Cohen's d = 0.151, small effect size). The values obtained from the two laboratories were very similar for identifying traumatic intracranial abnormalities (sensitivity = 80.1% versus 85.7%). CONCLUSIONS: The serum S100B results measured using the same assay in different laboratories yielded highly correlated and clinically similar, but clearly not identical, results.

Primary Objective: Mild Traumatic Brain Injury (MTBI) is commonly categorized as complicated when injury severity criteria are mild, but an intracranial abnormality is present on acute neuroimaging. The current study examined whether functional outcomes differed at one week post injury among older adult patients based on injury severity and acute computed tomography (CT) findings.Research Design: Participants (≥55 years-old; n = 173) presenting sequentially to the emergency department with a head injury were divided into three groups: complicated MTBI (positive CT; n = 22), uncomplicated MTBI (negative CT; n = 68), and mild head injury (unperformed CT, no documented loss of consciousness or post-traumatic amnesia; n = 83).Methods and Procedures: At one week post injury, the Modified Rankin Scale (i.e., difference score between pre/post-injury ratings; ∆MRS), Glasgow Outcome Scale-Extended (GOS-E), and Rivermead Post-Concussion Symptoms Questionnaire (RPQ) were administered.Main Outcomes and Results: Participants differed on the ∆MRS and GOS-E, but not the RPQ. The complicated MTBI group had worse GOS-E ratings than the uncomplicated MTBI and mild head injury groups and worse ∆MRS than the mild head injury group, but the uncomplicated MTBI and mild head injury groups did not differ on either outcome.Conclusions: Macrostructural abnormality on CT was associated with worse functional outcome at one week post MTBI.

Objectives: The purpose of this study was to determine the unique characteristics of violence-related traumatic brain injuries (TBI). Methods: All consecutive patients who underwent head CT due to an acute head injury (n = 3023) at the Emergency Department of Tampere University Hospital (Aug 2010-Jul 2012) were included. A detailed retrospective data collection was conducted in relation to demographics, injury-related data, premorbid health, clinical characteristics, and neuroimaging findings. Results: Patients with violence-related TBIs (n = 222) were compared to patients who sustained a TBI by other mechanisms (n = 2801). Statistically significant differences were found on age, gender, prior circulatory system disease, prior mental or behavioral disorders, chronic alcohol abuse, regular substance abuse, regular medication, alcohol intoxication at the time of injury, narcotics intoxication at the time of injury, and acute traumatic lesion on head CT. The groups did not differ on clinical signs of TBI severity. Conclusions: Young adult males with premorbid mental health history and chronic alcohol abuse are most prone to sustain a TBI due to a violence-related incident. Incidents are often related to alcohol intoxication. However, violence was not consistently associated with more severe TBIs than other mechanisms of injury.
