Clinical benefit following the implementation of a specialized urgent stroke care system]

BACKGROUND AND OBJECTIVE: Several strategies as stroke teams, stroke code teams, or stroke units development have demonstrated to improve stroke care quality. The potential benefit of implementing them as a whole has not been studied. We aimed to test the clinical efficacy of a specialized and urgent stroke assistance system in a Universitary Hospital, as well as the specific impact of each part of the system on several clinical indicators. PATIENTS AND METHOD: The implementation of the system followed three consecutive steps: stroke team and stroke code development, stroke unit creation and finally on-call stroke neurologists incorporation. Several clinical indicators to evaluate results have been selected. We compared data available before system onset (1992-1997) with data obtained during the system implementation (1998-2002). Modification in the results indicators following each of the individual steps of the system was also evaluated. RESULTS: During the five years of the system implementation, 5843 stroke patients have been prospectively studied. Admission and readmission necessities were reduced up to 34.2% and 81.8% respectively. Length of stay progressively decreased from 18 (pre-1998) to 7 days (2002). In-hospital mortality and institutionalization necessities were reduced to 50.1% and 50.5% respectively. The third step, in which on-call stroke neurologist were incorporated to the system, has demonstrated to be the most efficient in decreasing the length of stay, hospital mortality and institutionalization necessities. CONCLUSIONS: The creation of a specialized urgent stroke care system, protocol based and developed in stroke units, improves the medical assistance quality for stroke patients. Stroke neurologists on-call have a relevant role in the system working.
