The LACE+ (hospital Length of stay, Admission acuity, Comorbid conditions, and Emergency department use within 6 months of admission, plus other relevant factors) calculated at both admission (aLACE+) and discharge (dLACE+) predicts mortality risk among patients with stroke, according to study findings published in Neurology Clinical Practice.

Researchers conducted a retrospective review of a prospectively accrued cohort to explore whether aLACE+ and dLACE+ indices were independently related to 90-day mortality following stroke. Adults who presented with ischemic or hemorrhagic strokes between January 2018 and December 2021 were eligible for inclusion and categorized as high (score, ≥78), medium to high (score, 59-77), or low to medium (score, 0-58) risk. The primary outcome was mortality at 90 days after the index hospitalization. Cox regression models were used in statistical analysis.

A total of 2729 patients (median age, 70; men, 51.9%) were included in the study, of whom 474 (17.3%) died in the hospital or were discharged to hospice. 

Future studies are warranted to determine whether LACE+ score-based risk stratification can be used to devise early interventions to mitigate the risk for death,

According to the Kaplan-Meier analysis, cumulative 90-day survival was higher among patients in the low to medium vs medium to high or high aLACE+ risk categories (P <.001).

A higher aLACE+ risk category was independently associated with a higher mortality risk at 90 days (adjusted hazard ratio [aHR], 1.36; 95% CI, 1.13-1.64; P =.001), according to ordinal analysis. This association was sustained after excluding patients with withdrawal of life sustaining therapies (aHR, 1.57; 95% CI, 1.03-2.40; P =.035).

Overall, participants in the high vs low to medium aLACE+ risk category had a 62.9% higher risk for death within 90 days (aHR, 1.69; 95% CI, 1.06-2.69; P =.027) in categorical analysis. Participants in the medium to high vs low to medium aLACE+ risk category also had a 58.7% higher 90-day mortality risk (aHR, 1.42; 95% CI, 1.14-1.78; P =.002).

Similarly, cumulative 90-day survival in participants without withdrawal of life sustaining therapies was higher among patients in the low to medium vs medium to high or high aLACE+ risk categories (P <.001).

A higher dLACE+ risk category was independently associated with a higher mortality risk at 90 days (aHR, 1.82; 95% CI, 1.31-2.53).

Participants in the high vs low to medium LACE+ risk category had an 80.2% higher risk for death within 90 days. Compared with low to medium, high (aHR, 6.18; 95% CI, 1.90-20.13; P =.002) and medium to high (aHR, 4.04; 95% CI, 1.27-12.88; P =.018) dLACE+ risk categories were associated with greater mortality risk.

This study was limited by its retrospective, single-center design.

“Future studies are warranted to determine whether LACE+ score-based risk stratification can be used to devise early interventions to mitigate the risk for death,” the study authors concluded.
