| Abstract | dc.description.abstract | Background: Stroke is the second specific cause of death in Chile,
with a mortality rate of 48.6 per 100.000 inhabitans. It accounts for 6% of all hospitalizations
among adults. Aim: To study the type of patients hospitalized at a Stroke Unit in a general
hospital and the costs and benefits of such unit. Material and methods: A descriptive and
retrospective study using a patient registry, developed in Access® that included separate sections
for ischemic and hemorrhagic stroke. Established diagnostic criteria were used. The mean costs
per patient and complications were also calculated. Results: During 2003, 425 stroke patients
were admitted to our hospital and 105 (age range 30-89 years, 58% female) were hospitalized
at the Stroke Unit. Eighty three percent had ischemic and 16% had hemorrhagic stroke. The
most common etiologies were thrombosis in 41%, embolism in 36%, lacunar in 13%, arterial
dissection in 5% and transient ischemic attack in 3%. Fifty eight percent of patients had partial
anterior ischemic stroke (PACI), 73% had hypertension and 29.5% diabetes. Only 18% arrived
to the Stroke Unit with less of 6 hours of evolution, 7% of patients were admitted within the 3
hours after the onset of symptoms and 18%, from 3 to 6 hours. The mean lenght of stay in the
Stroke Unit was 6.6 days and at the hospital 9.9 days (p <0.01). The mean costs per patient at
the Stroke Unit and at the hospital were US$ 5.550 and US$ 4.815, respectively (p =ns).
Conclusions: The Stroke Unit decreases hospital stay days without raising costs importantly.
The inclusion criteria for stroke patients admitted to the Unit were adequate and the stroke
registry allowed a good assessment of the Unit operation. | en |
