Multicenter Study Clinical Trial Controlled Clinical TrialQuality management in traumatic brain injury (TBI) lessons from the prospective study in 6.800 patients after acute TBI in respect of neurorehabilitation.
Preliminary results on epidemiology, acute hospital care, and neurorehabilitation of TBI are presented of the first ever prospective controlled German study to analyse the use of regional structures and quality management as provided by the German social healthcare system. The sum of inhabitants in Hannover and Münster area was 2,114 million. Within an area of 100 kilometres diameter each. 6.783 acute TBI (58% male) were admitted for acute treatment from March 2000 to 2001. ⋯ The management of frequent complications in 148 patients (=57%) and the high number of one or more different consultations (n = 196) confirmed the author's concept for early neurosurgical rehabilitation in TBI when rehabilitation centres were compared regarding GCS and GOS: Early GOS 1 = 4%; GOS 2 = 2,7%, GOS 3 = 37,3%, GOS 4 = 26,7%, GOS 5 = 29,3%, final GOS scores were 1 = 1,2%, 2 = 1,7%, 3 = 21,8%, 4 = 36,2%, and 5 = 39,1% of all patients at the end of rehabilitation. Mean duration for both "B" and "C" was 41 days compared to 80 days for "D" and "E". An assessment of both GCS and GOS was insufficient.

Multicenter Study Clinical TrialQuantification of secondary CPP insult severity in paediatric head injured patients using a pressure-time index.
This paper describes and validates a new Cumulative Pressure-Time Index (CPT) which takes into account both duration and degree of cerebral perfusion pressure (CPP) derangement and determines critical thresholds for CPP, in a paediatric head injury dataset. Sixty-six head-injured children, with invasive minute-to-minute intracranial pressure (ICP) and blood pressure monitoring, had their pre-set CPP derangement episodes (outside the normal range) identified in three childhood age-bands (2-6, 7-10, and 11-16 years) and global outcome assessed at six months post injury. The new cumulative pressure-time index more accurately predicted outcome than previously used summary measures and by varying the threshold CPP values, it was found that these physiological threshold values (< or = 48, < or = 52 and < or = 56 mmHg for 2-6, 7-10, and 11-16 years respectively) best predicted brain insult in terms of subsequent mortality and morbidity.

Multicenter Study Clinical TrialWhich paediatric head injured patients might benefit from decompression? Thresholds of ICP and CPP in the first six hours.
Severe head injury in childhood continues to be associated with considerable mortality and morbidity. Early surgical decompression may be beneficial and the objective of this study was to examine the relationship between age-related thresholds of mean intracranial pressure (ICP) and cerebral perfusion pressure (CPP) over the first 6 hours and age outcome in paediatric head injury patients. A total of 209 head injured children admitted to five UK hospitals were studied. ⋯ At a CPP of 50 mmHg the specificity varied between the age groups (2 to 6 years: 0.47, 7 to 10 years: 0.28 and 11 to 16 years: 0.10) and similarly for an ICP of 25 mmHg (2 to 6 years: 0.53, 7 to 10 years: 0.44 and 11 to 16 years: 0.38). Younger children may be able to tolerate lower perfusion pressures and still have an independent outcome. Our threshold values for young children are likely to be important in the identification of patients who might benefit from new treatments such as surgical decompression.
