Abstract

Objective

To evaluate the impact that monitored acute stroke unit care may have on the risk of early neurological deterioration (END), and 90-day mortality and mortality-disability.

Methods

Non-randomized prospective study with consecutive patients with acute ischemic stroke (AIS) admitted to a conventional care stroke unit (CCSU), from May 2003 to April 2005, or to a monitored acute stroke unit (ASU) from May 2005 to April 2006. END was defined as an increase in the NIHSS score ≥ 4 points in the first 72 hours after admission.

Results

END was detected in 19.6 % of patients (11.2 % of patients admitted to the ASU and 23.8 % to the CCSU; p < 0.0001). Patients admitted to the ASU received more treatment with intravenous rtPa (13.5 % versus 4.2 %; p < 0.0001), had a shorter length of stay (9.1 [11.0] d versus 13.1 [10.4] d; p < 0.0001), lower 90-day mortality (10.2 % versus 17.3 %; p = 0.02), and lower mortality-disability at 90-days (28.4 % versus 40.2 %; p = 0.004) than those admitted to the CCSU. Multivariable analysis showed that ASU admission was a protector for END (OR: 0.37; 95 % CI: 0.23–0.62). On admission, higher NIHSS (OR: 1.06; 95 % CI: 1.03–1.10), higher glycaemia (OR: 1.003; 95 % CI: 1.001–1.006), and higher systolic pressure (OR: 1.01; 95 % CI: 1.002–1.017) were independent predictors of END.

Conclusions

END prevention by ASU care might be a key factor contributing to better outcome and decrease of length of stay in patients admitted to monitored stroke units.
