Outcomes of Acute Stroke Patients Requiring Mechanical Ventilation: Study Protocol for the SPICE Multicenter Prospective Observational Study

BACKGROUND

Care pathways and long-term outcomes of acute stroke patients requiring mechanical ventilation have not been thoroughly studied.

METHODS AND RESULTS

Stroke Prognosis in Intensive Care (SPICE) is a prospective multicenter cohort study which will be conducted in 34 intensive care units (ICUs) in the Paris, France area. Patients will be eligible if they meet all of the following inclusion criteria: (1) age of 18 years or older; (2) acute stroke (i.e., ischemic stroke, intracranial hemorrhage, or subarachnoid hemorrhage) diagnosed on neuroimaging; (3) ICU admission within 7 days before or after stroke onset; and (4) need for mechanical ventilation for a duration of at least 24 h. Patients will be excluded if they meet any of the following: (1) stroke of traumatic origin; (2) refusal to participate; and (3) privation of liberty by administrative or judicial decision. The primary endpoint is poor functional outcome at 1 year, defined by a score of 4 to 6 on the modified Rankin scale (mRS), indicating severe disability or death. Main secondary endpoints will include decisions to withhold or withdraw care, mRS scores at 3 and 6 months, and health-related quality of life at 1 year.

CONCLUSIONS

The SPICE multicenter study will investigate 1-year outcomes, ethical issues, as well as care pathways of acute stroke patients requiring invasive ventilation in the ICU. Gathered data will delineate human resources and facilities needs for adequate management. The identification of prognostic factors at the acute phase will help to identify patients who may benefit from prolonged intensive care and rehabilitation.

[Management of stroke in France. Results of 3 national surveys]

Three surveys were performed in France, in March 1999, to analyze the management of acute stroke patients. Three hundred forty five Emergency departments, 93 departments of Neurology and 258 Rehabilitation units participated. Fifty per cent of patients with stroke arrive at the emergency department within 3 hours of symptom onset. Only 40 p. cent of the patients are admitted in a neurological department and 5 p. cent in an acute stroke unit. The mean length of acute hospital stay is often very long (more than three weeks) because of the delay to transfer to a rehabilitation unit. This study shows that acute stroke management is herogeneous and not structured in France.

MRI and neurological complications of adult T-cell leukemia/lymphoma

We report the assessment by MRI of a lumbosacral lymphomatous localization of adult T-cell leukemia/lymphoma (ATLL) with human T-cell lymphotropic virus-1 infection in an African patient. Brain MRI detected associated multifocal lesions of increased signal intensity in the subcortical white matter. These MRI abnormalities are compatible with reported necropsy findings in cases of ATLL with neurological complications.
