RESUMO

BACKGROUND: Patients with advanced critical illness often receive more intensive treatment than they would choose for themselves, which contributes to high health care costs near the end of life. The purpose of this study was to determine whether a family support intervention delivered by the interprofessional ICU team decreases hospitalization costs and hospital readmissions among critically ill patients at high risk of death or severe functional impairment. RESULTS: We examined index hospitalization costs as well as post-discharge utilization of acute care hospitals, rehabilitation and skilled nursing facilities, and hospice services for the PARTNER trial, a multicenter, stepped-wedge, cluster randomized trial of an interprofessional ICU family support intervention. We determined patients' total controllable and direct variable costs using a computerized accounting system. We determined post-discharge resource utilization (as defined above) by structured telephone interview at 6-month follow-up. We used multiple variable regression modelling to compare outcomes between groups. Compared to usual care, the PARTNER intervention resulted in significantly lower total controllable costs (geometric mean: $26,529 vs $32,105; log-linear coefficient: - 0.30; 95% CI - 0.49, - 0.11) and direct variable costs ($3912 vs $6034; - 0.33; 95% CI - 0.56, - 0.10). A larger cost reduction occurred for decedents ($20,304 vs. $26,610; - 0.66; 95% CI - 1.01, - 0.31) compared to survivors ($31,353 vs. $35,015; - 0.15; 95% CI - 0.35,0.05). A lower proportion in the intervention arm were re-admitted to an acute care hospital (34.9% vs 45.1%; 0.66; 95% CI 0.56, 0.77) or skilled nursing facility (25.3% vs 31.6%; 0.63; 95% CI 0.47, 0.84). CONCLUSIONS: A family support intervention delivered by the interprofessional ICU team significantly decreased index hospitalization costs and readmission rates over 6-month follow-up.

RESUMO

BACKGROUND: Patients resuscitated from cardiac arrest have variable severity of primary hypoxic ischemic brain injury (HIBI). Signatures of primary HIBI on brain imaging and electroencephalography (EEG) include diffuse cerebral edema and burst suppression with identical bursts (BSIB). We hypothesize distinct phenotypes of primary HIBI are associated with increasing cardiopulmonary resuscitation (CPR) duration. METHODS: We identified from our prospective registry of both in-and out-of-hospital CA patients treated between January 2010 to January 2020 for this cohort study. We abstracted CPR duration, neurological examination, initial brain computed tomography gray to white ratio (GWR), and initial EEG pattern. We considered four phenotypes on presentation: awake; comatose with neither BSIB nor cerebral edema (non-malignant coma); BSIB; and cerebral edema (GWR ≤ 1.20). BSIB and cerebral edema were considered as non-mutually exclusive outcomes. We generated predicted probabilities of brain injury phenotype using localized regression. RESULTS: We included 2,440 patients, of whom 545 (23%) were awake, 1,065 (44%) had non-malignant coma, 548 (23%) had BSIB and 438 (18%) had cerebral edema. Only 92 (4%) had both BSIB and edema. Median CPR duration was 16 [IQR 8-28] minutes. Median CPR duration increased in a stepwise manner across groups: awake 6 [3-13] minutes; non-malignant coma 15 [8-25] minutes; BSIB 21 [13-31] minutes; cerebral edema 32 [22-46] minutes. Predicted probability of phenotype changes over time. CONCLUSIONS: Brain injury phenotype is related to CPR duration, which is a surrogate for severity of HIBI. The sequence of most likely primary HIBI phenotype with progressively longer CPR duration is awake, coma without BSIB or edema, BSIB, and finally cerebral edema.

RESUMO

Background: Anticonvulsant prophylaxis (ACP) for early post-traumatic seizures (PTS) is recommended in patients with traumatic brain injury (TBI). Phenobarbital (PB) may be used to prevent alcohol withdrawal syndrome (AWS) in at-risk patients. The dual-purpose use of PB in the TBI population would allow for consolidation of pharmacotherapy. Objective: The primary objective of this study was to determine the frequency of early PTS in TBI patients at risk of AWS treated with PB as ACP. Secondary objectives included determining rates of over sedation and endotracheal intubation. Methods: Patients received an intravenous (IV) loading dose of PB at 15-20 mg/kg followed by 1 mg/kg every 12 hours for 7 days with a goal level of 15-20 mcg/mL. Medication data, seizure frequency, and episodes of over sedation and endotracheal intubation were collected. Results: Eighty patients were treated with PB over a 1-year period. Thirty-nine patients were analyzed. Median loading dose was 19.9 (Interquartile Range 19.1-20.0) mg/kg with a median post load level of 21.7 mcg/mL (IQR 18.3-25.8) mcg/mL. One patient (2.6%) had electrographic evidence for early PTS. PB was discontinued in 4 (10.3%) patients out of concern for over sedation. One patient required endotracheal intubation after rapid PB loading. Conclusion: The frequency of early PTS was low when PB was used as primary ACP in patients with TBI at risk for AWS. Over sedation is a potential adverse effect that should be considered in the choice of ACP. No conclusions can be drawn as to the effectiveness of PB in preventing AWS.

RESUMO

BACKGROUND: Some patients resuscitated from out-of-hospital cardiac arrest (OHCA) progress to death by neurological criteria (DNC). We hypothesized that initial brain imaging, electroencephalography (EEG), and arrest characteristics predict progression to DNC. METHODS: We identified comatose OHCA patients from January 2010 to February 2020 treated at a single quaternary care facility in Western Pennsylvania. We abstracted demographics and arrest characteristics; Pittsburgh Cardiac Arrest Category, initial motor exam and pupillary light reflex; initial brain computed tomography (CT) grey-to-white ratio (GWR), sulcal or basal cistern effacement; initial EEG background and suppression ratio. We used two modeling approaches: fast and frugal tree (FFT) analysis to create an interpretable clinical risk stratification tool and ridge regression for comparison. We used bootstrapping to randomly partition cases into 80% training and 20% test sets and evaluated test set sensitivity and specificity. RESULTS: We included 1,569 patients, of whom 147 (9%) had diagnosed DNC. Across bootstrap samples, >99% of FFTs included three predictors: sulcal effacement, and in cases without sulcal effacement, the combination of EEG background suppression and GWR ≤ 1.23. This tree had mean sensitivity and specificity of 87% and 81%. Ridge regression with all available predictors had mean sensitivity 91 % and mean specificity 83%. Subjects falsely predicted as likely to progress to DNC generally died of rearrest or withdrawal of life sustaining therapies due to poor neurological prognosis. Two of these cases awakened from coma during the index hospitalization. CONCLUSIONS: Sulcal effacement on presenting brain CT or EEG suppression with GWR ≤ 1.23 predict progression to DNC after OHCA.

RESUMO

OBJECTIVE: To determine whether telemedicine technology can be used to reliably determine the neurologic diagnosis of death (NDD) in patients with catastrophic brain injury (CBI). METHODS: We included a convenience sample of patients with CBI at a single academic medical center from November 2016 through June 2018. We simultaneously performed brain death evaluation at the bedside and remotely via telemedicine. Remote examiners were neurointensivists who were experienced and knowledgeable in the NDD. In addition to standard clinical examination, we used quantitative pupillometry to evaluate pupil size and reactivity. We determined the proportion of agreement for each NDD examination element and the overall diagnosis of brain death between bedside and remote examiners. RESULTS: Twenty-nine patients with mean age 46 ± 18 years underwent 30 paired NDD examinations. Twenty-eight (97%) patients met the NDD criteria and were pronounced dead. One patient did not meet the NDD criteria and died after withdrawal of life support. With the exception of qualitative assessment of pupillary reactivity, we observed excellent agreement (97%-100% across NDD examination elements) between bedside and remote examiners and 97% agreement on the overall diagnosis of brain death. Unlike qualitative pupillary assessment, quantitative pupillometry was consistently interpretable by remote examiners. CONCLUSIONS: Our results suggest that remote telemedicine technology can be used to verify the findings of bedside examiners performing NDD examinations when a pupillometer is used to assess pupillary reactivity. When performed by neurocritical care experts, the telemedicine NDD examination has potential to facilitate timely and accurate certification of brain death in patients with CBI. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence on the concordance of neurologic diagnosis of death by telemedicine and bedside examiners.

RESUMO

INTRODUCTION: Although shortcomings in clinician-family communication and decision making for incapacitated, critically ill patients are common, there are few rigorously tested interventions to improve outcomes. In this manuscript, we present our methodology for the Pairing Re-engineered Intensive Care Unit Teams with Nurse-Driven Emotional support and Relationship Building (PARTNER 2) trial, and discuss design challenges and their resolution. METHODS AND ANALYSIS: This is a pragmatic, stepped-wedge, cluster randomised controlled trial comparing the PARTNER 2 intervention to usual care among 690 incapacitated, critically ill patients and their surrogates in five ICUs in Pennsylvania. Eligible subjects will include critically ill patients at high risk of death and/or severe long-term functional impairment, their main surrogate decision-maker and their clinicians. The PARTNER intervention is delivered by the interprofessional ICU team and overseen by 4-6 nurses from each ICU. It involves: (1) advanced communication skills training for nurses to deliver support to surrogates throughout the ICU stay; (2) deploying a structured family support pathway; (3) enacting strategies to foster collaboration between ICU and palliative care services and (4) providing intensive implementation support to each ICU to incorporate the family support pathway into clinicians' workflow. The primary outcome is surrogates' ratings of the quality of communication during the ICU stay as assessed by telephone at 6-month follow-up. Prespecified secondary outcomes include surrogates' scores on the Hospital Anxiety and Depression Scale, the Impact of Event Scale, the modified Patient Perception of Patient Centredness scale, the Decision Regret Scale, nurses' scores on the Maslach Burnout Inventory, and length of stay during and costs of the index hospitalisation.We also discuss key methodological challenges, including determining the optimal level of randomisation, using existing staff to deploy the intervention and maximising long-term follow-up of participants. ETHICS AND DISSEMINATION: We obtained ethics approval through the University of Pittsburgh, Human Research Protection Office. The findings will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT02445937.

RESUMO

BACKGROUND: We compared the characteristics and outcomes of post-arrest donors to those of other donors, described the proportion of post-arrest decedents who donated, and compared their characteristics to post-arrest decedents who did not donate. METHODS: We performed a retrospective cohort study including patients who died at a single academic medical center from January 1, 2010 to February 28, 2019. We linked our registry of consecutive post-arrest patients to donation-related data from the Center for Organ Procurement and Recovery (CORE). We used data from CORE to identify donor eligibility, first person designation, family approaches to seek consent for donation, and approach outcomes. We determined number of organs procured and number transplanted, stratified by donor type (brain death donors (BDD) vs donors after circulatory determination of death (DCD)). RESULTS: There were 12,130 decedents; 1525 (13%) were resuscitated from cardiac arrest. CORE staff approached families of 836 (260 (31%) post-arrest, 576 (69%) not post-arrest) to request donation. Post-arrest patients and families were more likely to authorize donation (172/260 (66%) vs 331/576 (57%), P = 0.02), and more likely to be DCDs (50/146 (34%) vs 55/289 (19%), P < 0.001). Overall, 4.1 ±â€¯1.5 organs were procured and 2.9 ±â€¯1.9 transplanted per BDD, which did not differ by post-arrest status, 3.2 ±â€¯1.2 organs were procured and 1.8 ±â€¯1.1 transplanted per DCD. Number of organs transplanted per DCD did not differ by post-arrest status. Unfavorable arrest characteristics were more common among post-arrest organ donors compared to non-donors. CONCLUSION: Patients resuscitated from cardiac arrest with irrecoverable brain injury have excellent potential to become organ donors.

RESUMO

BACKGROUND: Surrogate decision makers for incapacitated, critically ill patients often struggle with decisions related to goals of care. Such decisions cause psychological distress in surrogates and may lead to treatment that does not align with patients' preferences. METHODS: We conducted a stepped-wedge, cluster-randomized trial involving patients with a high risk of death and their surrogates in five intensive care units (ICUs) to compare a multicomponent family-support intervention delivered by the interprofessional ICU team with usual care. The primary outcome was the surrogates' mean score on the Hospital Anxiety and Depression Scale (HADS) at 6 months (scores range from 0 to 42, with higher scores indicating worse symptoms). Prespecified secondary outcomes were the surrogates' mean scores on the Impact of Event Scale (IES; scores range from 0 to 88, with higher scores indicating worse symptoms), the Quality of Communication (QOC) scale (scores range from 0 to 100, with higher scores indicating better clinician-family communication), and a modified Patient Perception of Patient Centeredness (PPPC) scale (scores range from 1 to 4, with lower scores indicating more patient- and family-centered care), as well as the mean length of ICU stay. RESULTS: A total of 1420 patients were enrolled in the trial. There was no significant difference between the intervention group and the control group in the surrogates' mean HADS score at 6 months (11.7 and 12.0, respectively; beta coefficient, -0.34; 95% confidence interval [CI], -1.67 to 0.99; P=0.61) or mean IES score (21.2 and 20.3; beta coefficient, 0.90; 95% CI, -1.66 to 3.47; P=0.49). The surrogates' mean QOC score was better in the intervention group than in the control group (69.1 vs. 62.7; beta coefficient, 6.39; 95% CI, 2.57 to 10.20; P=0.001), as was the mean modified PPPC score (1.7 vs. 1.8; beta coefficient, -0.15; 95% CI, -0.26 to -0.04; P=0.006). The mean length of stay in the ICU was shorter in the intervention group than in the control group (6.7 days vs. 7.4 days; incidence rate ratio, 0.90; 95% CI, 0.81 to 1.00; P=0.045), a finding mediated by the shortened mean length of stay in the ICU among patients who died (4.4 days vs. 6.8 days; incidence rate ratio, 0.64; 95% CI, 0.52 to 0.78; P<0.001). CONCLUSIONS: Among critically ill patients and their surrogates, a family-support intervention delivered by the interprofessional ICU team did not significantly affect the surrogates' burden of psychological symptoms, but the surrogates' ratings of the quality of communication and the patient- and family-centeredness of care were better and the length of stay in the ICU was shorter with the intervention than with usual care.

RESUMO

INTRODUCTION: An emergency surgical airway (ESA) is widely recommended for securing the airway in critically ill patients who cannot be intubated or ventilated. Little is known of the frequency, clinical circumstances, management methods, and outcomes of hospitalized critically ill patients in whom ESA is performed outside the emergency department or operating room environments. METHODS: We retrospectively reviewed all adult patients undergoing ESA in our intensive care units (ICUs) and other hospital units from 2008 to 2012 following activation of our difficult airway management team (DAMT). RESULTS: Of 207 DAMT activations for native airway events, 22 (10.6%) events culminated in an ESA, with 59% of these events occurring in ICUs with the remainder outside the ICU in the context of rapid response team activations. Of patients undergoing ESA, 77% were male, 63% were obese, and 41% had a history of a difficult airway (DA). Failed planned or unplanned extubations preceded 61% of all ESA events in the ICUs, while bleeding from the upper or lower respiratory tract led to ESA in 44% of events occurring outside the ICU. Emergency surgical airway was the primary method of airway control in 3 (14%) patients, with the remainder of ESAs performed following failed attempts to intubate. Complications occurred in 68% of all ESAs and included bleeding (50%), multiple cannulation attempts (36%), and cardiopulmonary arrest (27%). Overall hospital mortality for patients undergoing ESA was 59%, with 38% of deaths occurring at the time of the airway event. CONCLUSION: An ESA is required in approximately 10% of DA events in critically ill patients and is associated with high morbidity and mortality. Efforts directed at early identification of patients with a difficult or challenging airway combined with a multidisciplinary team approach to management may reduce the overall frequency of ESA and associated complications.

RESUMO

BACKGROUND: Rapid response teams (RRTs) have been widely accepted as useful adjuncts to the care of inpatients with unanticipated emergencies. One study suggested that leadership of such teams could be assigned to midlevel providers, especially when nonhospitalized person (NHP)-related emergencies occur. However, in our tertiary medical center, a critical care medicine (CCM) physician always leads all RRT events including those related to NHPs. OBJECTIVE: In this study, we postulate reasons in favor of a single structured RRT led by an intensivist for both inpatients and NHPs. METHODS: An observational study conducted at an academic medical center. Demographic and clinical characteristics of NHP-related RRT events were evaluated over a 9-month period. MEASUREMENTS AND MAIN RESULTS: Rapid response teams were activated 1,952 times, of which, 154 events were NHP related. Only 42 RRT activations occurred for employees and visitors. Most of the NHP activations (112 events) occurred in response to events involving persons who were on the premises because of preexisting illnesses, either visiting physician offices (46 events), undergoing ambulatory diagnostic procedures (30 events), in transit to the emergency department (13 events), or undergoing emergency psychiatry evaluation (11 events). Most patients (83 NHPs) required admission to the hospital including 22 NHPs to intensive care units (ICUs) either directly from the event location or subsequently from the emergency department. The physician team leader admitted 20 NHPs directly from the scene, of which, 13 were admitted directly to ICUs. CONCLUSION: Nonhospitalized patients requiring RRT activation often have complex pre-existent illnesses. A standardized team composition for both inpatients and NHPs in crisis is an appropriate administrative structure enhancing patient safety in hospitals where ambulatory and inpatient facilities are combined.

RESUMO

OBJECTIVE: The aim of this study was to determine the underlying characteristics of inpatients sustaining crisis events in the radiology department (RD). METHODS: This is a retrospective case series undertaken in a 715-bed university-based tertiary care referral center in the United States, with a well-established medical emergency response team (MET). Adult hospitalized inpatients sustaining crisis events in the radiology suites of the University of Pittsburgh Medical Center from November 1, 2008, to October 31, 2010, were reviewed. RESULTS: Ninety-six MET activations met our criteria. There were 92 conditions classified as C. Four conditions were characterized as A, defined as cardiopulmonary arrest. Three condition C calls progressed to cardiopulmonary arrest and were reclassified as A. A number of variables including admission diagnosis, comorbid conditions, time elapsed from admission to condition, admission source of patient, unit of origin before event, and the type of imaging study ordered were analyzed to determine any links or patterns between precursor events, the likelihood of deterioration, and the patient's subsequent clinical outcome.Forty (42%) of the conditions occurred within 24 hours of admission, and 49 (51%) occurred within the first 48 hours. Forty-six of the studies ordered were computed tomographic scans. Of those patients who sustained their condition within the first 48 hours, 41 (84%) were either outside hospital transfers or emergency department admissions. A significant proportion of acute deteriorations occurred in patients with traumatic brain injuries or strokes. Ten events (10%) were due to radiology accidents.Irrespective of etiology, the intervention of the MET allowed the study to be completed in 68 (71%) cases. Of these, 28 (41%) had their condition diagnosed by the study. Of the 10 patients who sustained a radiology accident, no patients had an adverse effect to their outcome; all were returned to their unit of origin. CONCLUSIONS: Inpatient deterioration in the RD often occurred early in the course of the patient's hospitalization, with more than 40% taking place in the first 24 hours of admission. The MET seemed to have a positive impact on many patients, allowing a substantial percentage of studies to be completed. Interpretation of those studies often identified the etiology of the deterioration. Further study of outside hospital transfers, emergency department admissions, and intensive care unit patients who deteriorate in the RD is warranted to clarify risk factors and to identify early signs of deterioration.

RESUMO

BACKGROUND: Current strategies for diagnosing ventilator-associated pneumonia (VAP) favor the use of quantitative methods; however, semi-quantitative cultures of endotracheal aspirates are still commonly used. METHODS: The microbiological results of patients with suspected VAP who had both quantitative cultures with non-bronchoscopic bronchoalveolar lavage (BAL) and semi-quantitative cultures of endotracheal aspirate obtained within 24 hours of each other were retrospectively reviewed and compared, using a quantitative threshold of >or=10(4) colony-forming units/mL as a reference standard. RESULTS: 256 patients with paired cultures were identified. Concordance between endotracheal aspirate (any growth of pathogens) and non-bronchoscopic BAL was complete in 58.2% and completely discordant in 23.8%. The sensitivity and specificity of endotracheal aspirate were 65.4% and 56.1%, which improved to 81.2% and 61.9% when antibiotic management decisions were considered in the analysis. Twenty-six patients had endotracheal aspirate cultures that were falsely negative for pathogens, with 61.5% of these patients demonstrating growth of non-fermenting Gram-negative rods or methicillin-resistant Staphylococcus aureus (MRSA) on non-bronchoscopic BAL. Overall, 45 patients (17.5%) among the entire cohort had false positive endotracheal aspirate cultures, with 19 of these patients (42.2%) demonstrating growth of non-fermenting Gram-negative rods or MRSA. CONCLUSIONS: Semi-quantitative cultures of endotracheal aspirate are poorly concordant with quantitative cultures obtained via non-bronchoscopic BAL. Although the performance of endotracheal aspirate improves when antibiotic treatment is considered, guiding therapy on the basis of semi-quantitative cultures may still result in failure to identify potentially multiple-drug-resistant pathogens, and would also tend to promote excessive antibiotic usage. Our data support the use of quantitative cultures in diagnosing VAP.

RESUMO

INTRODUCTION: Hyperthermia following a severe traumatic brain injury (TBI) is common, potentiates secondary injury, and worsens neurological outcome. Conventional fever treatment is often ineffective. An induced normothermia protocol, utilizing intravascular cooling, was used to assess the impact on fever incidence and intracranial pressure (ICP) in patients with severe TBI. METHODS: A comparative cohort study of 21 adult patients with severe TBI (GCS 25 mmHg was calculated for the initial 72-h monitoring period. Non-parametric rank tests were performed. RESULTS: Mean (+/-SD) or median [range] demographics did not differ between groups [total N = 42 (6 female, 36 male, age 36.4 +/- 14.8 years and initial GCS 7 [3-8], median and range]. Fever burden in the first 3 days (time >38 degrees C) in the induced normothermia versus control group was significantly less at 1.6% versus 10.6%, respectively (P = 0.03). Mean ICP for patients with induced normothermia versus control was 12.74 +/- 4.0 and 16.37 +/- 6.9 mmHg, respectively. Furthermore, percentage of time with ICP > 25 mmHg was significantly less in the induced normothermia group (P = 0.03). CONCLUSION: Induced normothermia (fever prophylaxis via intravascular cooling catheter) is effective in reducing fever burden and may offer a means to attenuate secondary injury, as evidenced by a reduction in the intracranial hypertension burden.

OBJECT: Current standard of care for patients with severe traumatic brain injury (TBI) is prophylactic treatment with phenytoin for 7 days to decrease the risk of early posttraumatic seizures. Phenytoin alters drug metabolism, induces fever, and requires therapeutic-level monitoring. Alternatively, levetiracetam (Keppra) does not require serum monitoring or have significant pharmacokinetic interactions. In the current study, the authors compare the EEG findings in patients receiving phenytoin with those receiving levetiracetam monotherapy for seizure prophylaxis following severe TBI. METHODS: Data were prospectively collected in 32 cases in which patients received levetiracetam for the first 7 days after severe TBI and compared with data from a historical cohort of 41 cases in which patients received phenytoin monotherapy. Patients underwent 1-hour electroencephalographic (EEG) monitoring if they displayed persistent coma, decreased mental status, or clinical signs of seizures. The EEG results were grouped into normal and abnormal findings, with abnormal EEG findings further categorized as seizure activity or seizure tendency. RESULTS: Fifteen of 32 patients in the levetiracetam group warranted EEG monitoring. In 7 of these 15 cases the results were normal and in 8 abnormal; 1 patient had seizure activity, whereas 7 had seizure tendency. Twelve of 41 patients in the phenytoin group received EEG monitoring, with all results being normal. Patients treated with levetiracetam and phenytoin had equivalent incidence of seizure activity (p = 0.556). Patients receiving levetiracetam had a higher incidence of abnormal EEG findings (p = 0.003). CONCLUSIONS: Levetiracetam is as effective as phenytoin in preventing early posttraumatic seizures but is associated with an increased seizure tendency on EEG analysis.

RESUMO

BACKGROUND: Cervical (C)-spine clearance protocols exist both to identify traumatic injury and to expedite rigid collar removal. Computed tomography (CT) of the C-spine in trauma patients facilitates the removal of immobilization collars in patients who are neurologically intact, and magnetic resonance imaging (MRI) has become an indispensable adjunct for evaluating trauma patients with neurologic deficits. Yet, the management of patients with impaired mental status who lack neurologic deficits attributable to the spinal cord remains controversial. C-spine MRI has been suggested and employed as an imaging modality to exclude occult C-spine instability in this population of patients. However, currently available data are inconclusive as to the necessity of MRI in the C-spine clearance of obtunded or comatose trauma patients with a normal CT. METHODS: The records of patients undergoing contemporaneous CT and MRI of the C-spine in a level I trauma center from January 2003 to December 2006 were retrospectively analyzed. From this group, patients admitted with a Glasgow Coma Scale score
