Acute care in stroke: do stroke units make the difference?
The consideration of stroke as a medical emergency and the development of new specific treatments to be applied in a narrow therapeutic window have shown the need to establish an adequate organization system for the management of stroke. It should be considered as an integral process both outside and inside the hospital. General care is essential and must already start outside the hospital, and comprises respiratory and cardiac care, fluid and metabolic management, especially blood glucose control, avoiding the administration of glucose solutions, blood pressure control, early treatment of hyperthermia and prevention and treatment of neurologic and systemic complications. In the early 70s, the first stroke units (SU) were established as intensive-care SU, but failed to show improvement in terms of reduction of mortality-morbidity. Nowadays, the concept has changed to a non-intensive-care SU. The benefit of these SU has been amply demonstrated in terms of reduction in mortality and in long institutionalization, as well as better functional outcome compared with general wards, and the efficacy of a neurology ward compared to a general medicine department has also been shown, but at the moment there are no studies analyzing the differences between a stroke team (ST) in a department of neurology and a SU. In this regard, we have performed a sequential analysis comparing both SU and ST and demonstrated a reduction in length of stay, complications and acute care costs with an improvement in functional state at hospital discharge, a reduction in the discharge to nursing homes with an increase in patients translated into rehabilitation wards. With these data, we can conclude that SU, not ST are the most effective organizational model for acute stroke management. Definitely, the SU make the difference.
