Contraction stress test versus ductus venosus Doppler evaluation for the prediction of adverse perinatal outcome in growth-restricted fetuses with non-reassuring non-stress test.

OBJECTIVE: To compare Doppler evaluation of the ductus venosus and contraction stress test (CST) in the prediction of adverse perinatal outcome in growth-restricted fetuses with evidence of hemodynamic redistribution and a non-reactive non-stress test (NST). METHODS: Data were collected from all singleton pregnancies seen in our Fetal Surveillance Unit who underwent antenatal monitoring for fetal growth restriction, non-reactive NST and arterial redistribution beyond 26 weeks of pregnancy. Patients were divided into four groups based on their CST and ductus venosus waveform results. Perinatal outcome was evaluated by means of four variables: the need for admission to the neonatal intensive care unit (NICU), need for neonatal intubation, an umbilical artery pH < 7.10 and significant neonatal morbidity. Outcome was compared among fetuses delivered within 3 days of their antenatal test. Logistic regression analysis was used to analyze the relation between predictive and outcome variables. RESULTS: Sixty-eight women met the inclusion criteria for the study. The positive predictive value of the CST was 45% for admission to the NICU, 13% for significant neonatal morbidity, 26% for need of neonatal intubation and 29% for umbilical artery pH < 7.10. The positive predictive values of abnormal ductus venosus waveform (ADVW) were 81.5%, 26%, 48% and 55%. Groups with ADVW showed significantly poorer neonatal outcome. No significant differences were observed when CST results were compared. Logistic regression analysis showed that both gestational age at delivery and ADVW significantly predict the occurrence of adverse perinatal outcome. CONCLUSION: In growth-restricted fetuses with hemodynamic redistribution and a non-reassuring NST, Doppler assessment of the ductus venosus correlates with adverse perinatal outcome. In this clinical situation there is no benefit of CST in terms of prediction.

Neurological outcome following neonatal post-haemorrhagic hydrocephalus: the effects of maximum raised intracranial pressure and ventriculo-peritoneal shunting.

UNLABELLED: The neuromotor outcome of 33 survivors of grade 3 or 4 neonatal post-haemorrhagic hydrocephalus born between 1975 and 1988 was assessed at a mean age of 4.7 years (9 months to 13 years). Two outcomes were determined: 12 patients were either normal (10 or had neurological signs without functional impairments (2), while 21/33 were moderately (16), severely (2), or profoundly impaired (3). Intracranial pressure (ICP) was measured in 26/33 patients (4-40 mm Hg): 2 had normal pressures (< 5.6 mm Hg) and were normal. Raised ICP was not significantly different between outcome groups. Twenty-seven children were shunted; 10/27 had five or more operations (up to 14) and all of these had abnormal neurological outcomes, whereas the number of children with 1-4 shunt procedures was equal in both outcome groups. The rise in morbidity after the fourth shunt procedure may be associated with the ventriculitis suffered by 9 of the 10 patients with more than four shunts (P < 0.01): this compares with 4/14 cases of ventriculitis in the children with 2-4 shunts and no cases of infection in the 3/27 who were shunted once. Outcome was independent of antenatal and perinatal factors including the age at or mode of presentation, and was unrelated to grade of intraventricular haemorrhage or parenchymal changes on ultrasound or CT scanning. CONCLUSION: for these small numbers, adverse outcome is statistically related to more than four shunt procedures and ventriculitis but independent of maximum ICP or other perinatal factors.

Radiological and functional outcome after anterior lumbar interbody spinal fusion.

Outcome after anterior spinal fusion has mainly been studied radiologically and reported fusion rates vary greatly. The aim of this study was to investigate radiological and long-term clinical outcome. The study comprised 120 consecutive patients, operated on during the period 1979-1987, with single-or two-level anterior interbody spinal fusion due to disc degeneration or isthmic spondylolisthesis with lumbar instability. In 64 patients a supplemental facet joint fusion was performed. Clinical outcome was evaluated 5-13 years after surgery using the patient-administered Dallas Pain Questionnaire (DPQ). Radiological outcome was determined on the basis of radiographs taken at a 2-year follow-up assessed by independent observers. The radiological follow-up rate was 98%. Complete fusion was found in 52%, questionable fusion in 24%, and definitive pseudoarthrosis in 24% of patients. Radiological results were poor in patients who had undergone previous spinal surgery (P < 0.05) and in those with two-level fusion (P < 0.05). The DPQ reply rate was 80%. Sixty-six patients claimed improvement in all functional groups. Patients with complete or questionable union had significantly better results than did those with non-union (P < 0.01). Poorer functional outcome was found in patients who had undergone previous spinal surgery (P < 0.01) or fusion at the L4/L5 level (P < 0.05), in those who had responded poorly to the preoperative test brace (P < 0.05), and in those above 45 years old at the time of surgery (P < 0.05). Radiological and functional outcome did not vary according to whether patients were treated postoperatively with a plaster jacket or with facet screw fixation. The study demonstrated a functional success rate of approximately 66% following anterior lumbar spinal fusion after a mean follow-up of 8 years. There was a clear tendency for poorer prognosis for patients who had undergone previous spinal surgery, those aged above 45 years, those operated at the L4/L5 level and those who had responded poorly to the preoperative test brace. DPQ scores correlated well with radiological outcome.

Quality of mental health service care: the forgotten pathway from process to outcome.

The validity of the concept of outcome depends on a relationship between routine treatment and later health status. Outcome evaluations and audits are very rare in psychiatry. A substantial expansion in epidemiologically based, naturalistic, observational, process-outcome data collection in routine psychiatric practice is essential in order to identify treatment allocation biases and other reasons for unexpected outcomes. Identified causes of undertreatment should lead to locally agreed detailed clinical guidelines. Experimental evaluation should take place in routine clinical practice settings, with change in both process and outcome as the objective. Ultimately, the results of both experimental and observational outcome studies on representative service users should converge, permitting outcomes to be the ultimate arbitrator of quality.

Parent behavioral training: an analysis of the relationship among multiple outcome measures.

The purpose of the present study was to examine the relationship among three types of outcome measures that have been employed to evaluate parent behavioral trainining: observational data collected by independent observers, parent-collected data, and parent-completed questionnaires. Previous research suggests that all three measures yield positive outcome data; however, a correlational analysis has not been performed to determine if the subjects who demonstrate the largest (smallest) change on one measure demonstrate the largest (smallest) change on the other measures. The present study undertook such a correlational analysis. Subjects were 20 young clinic-referred children and their mothers. Treatment consisted of a standardized parent training program to modify child noncompliance. All three outcome measures (observational data, parent-collected data, and questionnaire data) indicated that therapy was effective. A correlational analysis performed on the outcome measures indicated a number of significant relationships for dependent variables within the observational data and within the questionnaire data; however, there were no significant relationships across the three outcome measures. Although different outcome measures may yield similar conclusions about the effectiveness of parent behavioral training, the results suggest that any one subject, relative to other subjects, does not demonstrate uniform degrees of change across the three outcome measures. Explanations for the findings, as well as their implications, are discussed.

The ecology of outcomes: system accountability in children's mental health.

This article provides a conceptual and practical framework called the Ecology of Outcomes. Based on this framework, agencies that serve children and families build and use outcome-oriented information systems to respond to their clients in a more flexible manner. The goal is to improve promising programs by involving stakeholders in outcome identification and in utilization of results. Problems addressed include the emphasis human services place on rules compliance, lack of feedback to program staff to allow for midcourse correction, and lack of input by key stakeholders in the identification of outcomes to be measured. The following components of the framework are described: principles of outcome accountability, prerequisites and building blocks, implementing an outcome information system, and utilizing the results. Key elements of the framework are the integration of outcome information into a service system's decision-making process and the inclusion of client, stakeholder, and provider satisfaction information.

Changes of nitric oxide and its relationship with clinical features, intracranial pressure and outcome in acute head injury.

To investigate the content and dynamics of nitric oxide (NO) in the cerebrospinal fluid (CSF) of patients with acute head injury and to clarify the relationship of NO with clinical features and intracranial pressure (ICP) as well as outcomes, 38 adults with acute head injury were studied. Glasgow Coma Scale (GCS) obtained at admission and Glasgow Outcome Scale (GOS) 3 months after injury was assessed. ICP was surveyed via intraventricular catheter and lumbar puncture and CSF samples were obtained simultaneously. NO was determined with Griess reagents. Results showed that NO peak content in the head injury group was significantly higher than that of the control group. During dynamic research, no peak content of mildly injured cases and severely injured ones appeared in different time windows respectively. The peak value of NO was distinctly higher in the severe group than in the mild group. NO peak value of the raised ICP group was remarkably higher than that of the normal ICP group. The peak value of NO was considerately higher in the poor outcome group than in the good outcome group. When the content of NO was over 6.5 mumol/L, the rate of poor outcome was increased. There existed a correlation between NO and GCS, ICP and GOS. It is concluded that the content of NO was increased in patients with acute head injury and the changes of NO had different time windows in severely injured patients and mildly injured ones. The more sever the injury, the higher the NO content; and the more serious the secondary brain injury and brain edema, the worse the outcomes. When NO is combined with GCS, GOS and ICP, it increases the accuracy of judgement to the degree of head injury and outcome.

Person-related predictors of employment outcomes after participation in psychiatric vocational rehabilitation programmes--a systematic review.

BACKGROUND: There is increasing recognition of the importance of psychiatric vocational rehabilitation (PVR) programmes in helping individuals with severe mental illnesses to find and secure jobs. However, little is known concerning the factors related to PVR outcomes. OBJECTIVE: This review identifies those person-related factors which most strongly influence employment outcomes after participation in PVR programmes. METHOD: Medline, Psychinfo, Pubmed and CINAHL were searched for studies using multivariate analysis of longitudinal data, which analysed employment outcomes after at least 6 months of programme participation, and which analysed at least three predictor domains. RESULTS: Eight studies presented in 16 publications met all the criteria. Better employment outcomes were most strongly related to better work performance measured during PVR participation and to higher work-related self-efficacy. Better social functioning during PVR participation was also significantly related to positive employment outcomes, but this relationship was generally weaker than those of the two aforementioned factors. In most studies, employment outcomes after PVR were not related to past functioning, including work history and diagnosis. Findings on the severity of psychiatric symptoms measured during PVR were mixed. In terms of contribution to outcome, severity of symptoms usually ranked below work performance, when measured concurrently. CONCLUSION: Contrary to previous reviews, this study suggests that the influence of past functioning, including work history, diagnosis and psychiatric history, is outweighed by work performance in PVR. Further prospective and controlled studies are needed to reach more definite conclusions about the individual contributions of person-related factors.

The feasibility of routine outcome measures in mental health.

BACKGROUND: Standardised outcome measures are not being used in routine mental health care. METHOD: The importance of routine use of standardised outcome measures is argued, and reasons for their lack of use suggested. RESULTS: One reason for standardised outcome measures not being used routinely is the lack of appropriate instruments. This property of being suitable for routine use is often called feasibility, but there is no consensus about the meaning of feasibility, or how it should be measured. We propose a definition of feasibility as a psychometric property of a standardised outcome measure, provide criteria for assessing feasibility, and then present a framework for changing practice to increase the routine use of standardised outcome measures. CONCLUSIONS: If mental health care is to maximise outcome, then more attention needs to be paid both to the process of developing and to facilitating the routine clinical use of feasible outcome measures.

Outcome assessment in psychiatric service evaluation.

BACKGROUND: The present paper gives an overview of outcome assessment issues in psychiatric service evaluation, based on seven proposals concerning the content and methodology of outcome assessment. It is stressed that outcome assessments should be performed on both the system and the patient level and that multiple outcome domains should be used, reflecting multiple perspectives of the services. It is also argued that outcome studies benefit from incorporating service use measures in order to enable analyses of costs and cost-effectiveness of services. Outcome studies of community-based psychiatric services have so far mainly investigated service models or programs. CONCLUSIONS: It is concluded that there is a need to investigate the relationship between particular parts and content of services and outcome, in order to increase knowledge of what is effective in community-based psychiatric services.

Specialist neurocritical care and outcome from head injury.

OBJECTIVES: To document the effect of neurocritical care, delivered by specialist staff and based on protocol-driven therapy aimed at intracranial pressure (ICP) and cerebral perfusion pressure (CPP) targets, on outcome in acute head injury. DESIGN: Retrospective record review to compare presentation, therapy and outcome in patients with head injury referred to a regional neurosurgical centre, before and after establishment of protocol-driven therapy. SETTING: Neurosciences Critical Care Unit (NCCU). PARTICIPANTS: Two hundred and eighty-five patients aged 18-65 years with at least one reactive pupil, referred with a diagnosis of head injury, requiring tracheal intubation and mechanical ventilation. INTERVENTIONS: Measurement of Glasgow Outcome Scale 6 months after injury. RESULTS: Patients from the two epochs were well matched for admission Glasgow Coma Scale and extracranial injuries. When all referred patients were considered, institution of protocol-driven therapy was not associated with a statistically significant increase in favourable outcomes (56.0% vs. 66.4%). However, we observed a significant increase in favourable outcomes in the severely head injured patients studied (40.4% vs. 59.6%). The proportion of favourable outcomes was also high (66.6%) in those presenting with evidence of raised ICP in the absence of a mass lesion and (60.0%) in those that required complex interventions to optimise ICP/CPP. CONCLUSIONS: Specialist neurocritical care with protocol-driven therapy is associated with a significant improvement in outcome for all patients with severe head injury. Such management may also benefit patients requiring no surgical therapy, some of whom may need complex therapeutic interventions. We found it impossible to predict need for such interventions from clinical features at presentation. These data suggest that specialist critical care with ICP/CPP guided therapy may benefit patients with severe head injury.

Impact of diffusion-weighted MRI-measured initial cerebral infarction volume on clinical outcome in acute stroke patients with middle cerebral artery occlusion treated by thrombolysis.

INTRODUCTION: Magnetic resonance imaging (MRI) may help identify acute stroke patients with a higher potential benefit from thrombolytic therapy. The aim of our study was to assess the correlation between initial cerebral infarct (CI) volume (quantified on diffusion-weighted MRI) and the resulting clinical outcome in acute stroke patients with middle cerebral artery (MCA) (M(1-2) segment) occlusion detected on MRI angiography treated by intravenous/intraarterial thrombolysis. METHODS: Initial infarct volume (V(DWI-I) ) was retrospectively compared with neurological deficit evaluated using the NIH stroke scale on admission and 24 h later, and with the 90-day clinical outcome assessed using the modified Rankin scale in a series of 25 consecutive CI patients. The relationship between infarct volume and neurological deficit severity was assessed and, following the establishment of the maximum V(DWI-I) still associated with a good clinical outcome, the patients were divided into two groups (V(DWI-I) < or =70 ml and >70 ml). RESULTS: V(DWI-I) ranged from 0.7 to 321 ml. The 24-h clinical outcome improved significantly (P=0.0001) in 87% of patients with a V(DWI-I) < or =70 ml (group 1) and deteriorated significantly (P=0.0018) in all patients with a V(DWI-I) >70 ml (group 2). The 90-day mortality was 0% in group 1 and 71.5% in group 2. The 90-day clinical outcome was significantly better in group 1 than in group 2 (P=0.026). CONCLUSION: Clinical outcome could be predicted from initial infarct volume quantified by MRI-DWI in acute CI patients with MCA occlusion treated by intravenous/intraarterial thrombolysis. Patients with a V(DWI-I) < or =70 ml had a significantly better outcome.

Extratemporal hypometabolism on FDG PET in temporal lobe epilepsy as a predictor of seizure outcome after temporal lobectomy.

We investigated the relationship between the presence of extratemporal hypometabolism on fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET) and seizure outcome after temporal lobectomy in patients with medically intractable temporal lobe epilepsy (TLE). In 47 patients with intractable unilateral mesial TLE, regional metabolic changes on FDG PET images obtained during the 2 months preceding anterior temporal lobectomy were compared with postoperative seizure outcome. Postoperative seizure outcome was evaluated with a mean follow-up period of 6.1+/-0.6 years (range 5.2-7.2 years). Forty-two (89%) of the 47 patients achieved a good postoperative seizure outcome (Engel class I or II). All patients had hypometabolism in the temporal cortex ipsilateral to the epileptogenic region on FDG PET scans. Fourteen (78%) of the 18 patients with hypometabolism only in the ipsilateral temporal cortex were completely seizure free (Engel class Ia) after surgery. In contrast, five (45%) of the 11 patients with extratemporal cortical hypometabolism confined to the ipsilateral cerebral hemisphere and only four (22%) of the 18 patients with hypometabolism in the contralateral cerebral cortex were completely seizure free after surgery. The postoperative seizure-free rates were significantly different across the three groups of patients with different cortical metabolic patterns ( P<0.005). Furthermore, all of the nine patients with a non-class I outcome (Engel class II-IV) had extratemporal (including contralateral temporal) cortical hypometabolism. Thalamic hypometabolism was noted in 20 (43%) of the 47 patients (ipsilateral in 12, bilateral in 8). Sixteen (59%) of the 27 patients with normal thalamic metabolism were completely seizure free after surgery, while only seven (35%) of the 20 patients with thalamic hypometabolism became completely seizure free ( P<0.05). Multivariate analysis revealed that among variables including clinical, EEG, magnetic resonance imaging, pathological and FDG PET metabolic findings, only cortical metabolic pattern was an independent factor for the prediction of postoperative seizure outcome ( P<0.005). It is concluded that extratemporal cortical hypometabolism outside the seizure focus, in particular hypometabolism in the contralateral cerebral cortex, may be associated with a poorer postoperative seizure outcome in TLE and may represent underlying pathology that is potentially epileptogenic. Thalamic hypometabolism, which was associated, but not independently, with a higher likelihood of postoperative seizures, may be secondary to extratemporal or temporal pathology.

Analysis of methodological deficiencies of studies reporting surgical outcome following cemented total-joint arthroplasty of trapezio-metacarpal joint of the thumb.

Cemented total-joint arthroplasty has been increasingly used in the treatment of end stage arthritis of the thumb trapeziometacarpal joint. Evidence supporting its use in the treatment of trapeziometacarpal disorders in the literature is very limited. Most hand surgeons agree that there are concerns about the methodological quality of the limited literature available. In this study, we analysed the methodological quality of the outcome studies on cemented total-joint arthroplasty of the thumb. We included all the outcome studies published in the English literature on cemented total-joint arthroplasty of the trapeziometacarpal joint of thumb. We analysed these studies for methodological deficiencies and quality of outcome reporting based on the recommendations given by Coleman et al. Our study revealed that there were no uniform standards of outcome reporting. The mean Coleman score for the studies dealing with cemented total-joint arthroplasty of the thumb was 42.9. Major deficiencies were identified in areas like subject selection criteria (0/15), type of study (5.7/15), description of surgical procedure (3.7/5), description of the rehabilitation protocol (2/10), outcome measures (4.4/10) and outcome assessment (3.9/15). The methodological quality of the studies published within the last 10 years (49.9+/-9.7) was found to be slightly better than the studies published over 10 years ago (39.7+/-7.8). Our study highlights the need for more evidence in the form of randomised controlled prospective studies conducted with good methodological quality, comparing the cemented total-joint arthroplasty of the thumb to other procedures available for the treatment of disorders of the thumb. Further, to improve the standards of reporting, journal editors should try to standardise the outcome of the reporting by following the surgical procedures on the thumb.

The impact of initial management on the outcome of children with severe head injury.

BACKGROUND: Neurotrauma is one of the most important causes of death in the pediatric age group. Head injury is responsible for both primary and secondary brain damage. The outcome of children with brain injury depends on the nature of the primary damage and on how well secondary brain damage can be limited. Appropriate critical care management at the scene and in hospital can prevent secondary brain damage that would otherwise result from cerebral reactions. Hypoxia and hypotension are major early complications of aggravation of secondary brain damage that are amenable to emergency maneuvers at the scene. In the literature, the influence of initial critical care management and early complications on the outcome of children with severe head injury is not clearly documented. METHODS AND RESULTS: We have prospectively examined the impact of the management at the scene on outcome in 40 children admitted to our Pediatric Intensive Care Unit with severe head injury (Glasgow Coma Scale < or = 8). The outcome of these children was assessed using the Glasgow Outcome Score (GOS). The results were evaluated by univariate and multivariate analysis. In our series the length of time before admission to an intensive care unit appears to have influenced the outcome among survivors, while the severity of injury is the only factor statistically associated with early complications (hypoxia and hypotension). With regard to the impact of early complications on outcome, the multivariate analysis showed that hypoxia and hypotension were significantly associated with GOS, independently of the GCS. CONCLUSION: Our results confirm the need for a precise treatment strategy for the initial management of children with neurotrauma to decrease the incidence of secondary brain damage attributable to hypoxia and hypotension.

Predictors of poor outcome after selective dorsal rhizotomy in treatment of spastic cerebral palsy.

OBJECTIVES: The purpose of the study was to determine if there are preoperative clinical characteristics that might be predictive of a poor outcome after selective dorsal rhizotomy (SDR) surgery in children with spastic cerebral palsy (CP). METHODS: A retrospective analysis was performed on 174 children who had undergone SDR from 1983 to 2001. Patients were divided into two groups according to their outcome at approximately 1 year after surgery: "acceptable" or "poor" outcome. As predictors of outcome, the factors compared were age at operation, types of CP (diplegia, quadriplegia), history of prematurity, prior lower limb orthopedic surgeries, history of seizures, dystonic limbs, opisthotonic posturing, lumbar hyperlordosis, truncal hypotonia, preoperative ambulatory function, preoperative Gross Motor Function Classification System (GMFCS) scores, and presence of intellectual delay and speech delay. RESULTS: Eleven children (6.3%) had a "poor" outcome. The type of CP (P<0.001) and intellectual delay (P=0.015) were significant predictors of outcome in the univariate regression analysis, but only the type of CP retained significant predictive power in the multivariate analysis. CONCLUSION: These data suggest that preoperative diagnosis is the strongest predictor of outcome after SDR. Intellectual delay demonstrated predictive power only in the univariate model, suggesting that it might have some prognostic value but less than the diagnosis.

Spontaneous supratentorial intracerebral hemorrhage. Criteria for short-term functional outcome prediction.

BACKGROUND AND PURPOSE: To identify the significant prognostic factors, upon admission, and construct a set of criteria to predict short-term functional outcome of patients with intracerebral hemorrhage (ICH). METHODS: The records as well as the radiological findings, of 184 consecutive cases of spontaneous supratentorial intracerebral hemorrhage, that were treated medically, were reviewed. The hemorrhage was graded according to size, mass effect and intraventricular extension. Outcome upon discharge was scored using the modified Rankin Scale. A score of four or more was considered a poor outcome. Multivariate analysis was used to identify the factors associated with a poor outcome. RESULTS: Six significant and independent prognostic variables were identified: decreased level of consciousness, severe hemiparesis, age older than sixty, large hematoma size, midline shift and intraventricular extension on CT. These variables were scored systematically to produce the ICH criteria. The sum of these criteria yields a figure between zero and six termed ICH score. Patient grouping according to ICH score identified four distinctive, prognostic groups: I - score of zero to one, II - score of two, III - score of three and IV - score of four to six in which 82%, 53.7%, 23.3% and 0% achieved a good outcome respectively (P < 0.05 for all groups). CONCLUSIONS: The present study identified six independent admission criteria predicting the short-term functional outcome of ICH patients. Their sum may serve to predict the short-term functional outcome upon admission of medically-treated patients with spontaneous supratentorial intracerebral hemorrhage.

Relationship between short-term outcome and occurrence of cerebral artery stenosis in survivors of bacterial meningitis.

To evaluate the influence of cerebral artery stenosis on the outcome of patients with bacterial meningitis we examined prospectively 47 consecutive patients [33 men, 14 women, mean (SD) age, 53 (17) years, range 18-81] with bacterial meningitis caused by various bacterial pathogens. The patients were examined with the use of the Glasgow Coma Scale (GCS) on days 1, 3, 5, 8, 14 and with the use of the Glasgow Outcome Scale (GOS) on day 21 after admission. In addition, focal cerebral signs were recorded separately. At each clinical examination, the patients underwent transcranial Doppler sonography recordings of the mean blood velocity (MBV) and the pulsatility index in all of the main intracranial arteries and in the submandibular internal carotid artery (ICA). A stenosis of the middle cerebral artery (MCA) was diagnosed by an MBV of > or = 120 cm/s or by an MBV ratio > 3 between the MCA and the ICA. An anterior cerebral artery (ACA) stenosis was indicated by an MBV > or = 100 cm/s, a posterior cerebral artery (PCA) stenosis by an MBV of > or = 85 cm/s, and a basilar artery (BA) stenosis by an MBV of > or = 95 cm/s. Twenty-five patients developed stenosis of the cerebral arteries (apart from 1, all within 8 days), 22 patients remained without stenosis. Of 29 focal cerebral signs, 27 occurred within 8 days. For outcome analysis, outcome was classified into two groups: not handicapped (GOS 5) versus handicapped (GOS 2-4) and dead (GOS 1). Based on the disease course up to day 8, risk factors for a handicapped/dead outcome after day 8 were advancing age (odds ratio per year, 1.06; 95% confidence interval (CI), 1.01-1.11; P = 0.03) and the presence of arterial stenosis (odds ratio, 7.3; 95% CI, 1.1-45) using a multivariate logistic regression analysis model. GCS on day 1, cerebrospinal fluid total protein content and the presence of focal cerebral signs were not significantly related to outcome in this series. The patients with stenosis exhibited significantly more frequently a poorer GCS on days 1-5 (Mann-Whitney U test; P < 0.05). In conclusion, the early occurrence of stenosis of the cerebral arteries in bacterial meningitis predicted a worse clinical course of the disease and a poorer short-term outcome of the survivors.
