Insights
A new tool using cardiovascular disease (CVD) clusters, called CASH, helps predict acute stroke outcomes. Higher CASH scores indicate increased risks for mortality, disability, and infections after stroke.
Area of Science:
- Neurology
- Cardiology
- Public Health
Background:
- Predicting outcomes after acute stroke remains challenging.
- Existing indicators for acute stroke outcomes are limited.
- Coexisting cardiovascular disease (CVD) may influence stroke outcomes.
Purpose of the Study:
- To develop and validate evidence-based criteria for identifying acute stroke outcomes.
- To assess the association between clusters of coexisting cardiovascular disease (CVD) and adverse stroke outcomes.
Main Methods:
- Analysis of prospectively collected data from the Sentinel Stroke National Audit Programme (SSNAP) between 2014 and 2016.
- Inclusion of 3309 patients admitted with acute stroke to UK hyperacute stroke units.
- Development of the Cardiovascular disease, Atrial fibrillation, pre-existing Stroke and Hypertension (CASH) score, categorizing patients into CASH-0 to CASH-3 based on the number of coexisting CVDs.
Main Results:
- Patients with CASH-3 (three or four coexisting CVDs) exhibited significantly higher risks of in-hospital mortality (OR=1.8) and disability at discharge (OR=1.9) compared to CASH-0.
- Increased risks of urinary tract infection (OR=3.3), pneumonia (OR=2.6), and prolonged length of stay (>14 days) (OR=1.8) were observed in the CASH-3 group.
- A higher likelihood of joint care planning (OR=1.4) was also associated with the CASH-3 category.
Conclusions:
- The CASH score serves as a simple, evidence-based tool for estimating the risk of adverse outcomes following acute stroke.
- CASH-0 signifies a low risk, while CASH-3 indicates a high risk for complications such as mortality, disability, infections, and prolonged hospital stay.
- This tool can aid clinicians in risk stratification and management planning for acute stroke patients.
Objective:
Indicators for outcomes following acute stroke are lacking. We have developed novel evidence-based criteria for identifying outcomes of acute stroke using the presence of clusters of coexisting cardiovascular disease (CVD).
Materials And Methods:
Analysis of prospectively collected data from the Sentinel Stroke National Audit Programme (SSNAP). A total of 1656 men (mean age ±SD=73.1yrs±13.2) and 1653 women (79.3yrs±13.0) were admitted with acute stroke (83.3% ischaemic, 15.7% intracranial haemorrhagic), 1.0% unspecified) in four major UK hyperacute stroke units (HASU) between 2014 and 2016. Four categories from cardiovascular disease Congestive heart failure, Atrial fibrillation, pre-existing Stroke and Hypertension (CASH).were constructed: CASH-0 (no coexisting CVD); CASH-1 (any one coexisting CVD); CASH-2 (any two coexisting CVD); CASH-3 (any three or all four coexisting CVD). These were tested against outcomes, adjusted for age and sex.
Results:
Compared to CASH-0, individuals with CASH-3 had greatest risks of in-hospital mortality (11.1% vs 24.5%, OR=1.8, 95%CI=1.3-2.7) and disability (modified Rankin Scale score ≥4) at discharge (24.2% vs 46.2%, OR=1.9, 95%CI=1.4-2.7), urinary tract infection (3.8% vs 14.6%, OR= 3.3, 95%CI= 1.9-5.5), and pneumonia (7.1% vs 20.6%, OR= 2.6, 95%CI= 1.7-4.0); length of stay on HASU >14 days (29.8% vs 39.3%, OR=1.8, 95%CI=1.3-2.6); and joint-care planning (20.9% vs 29.8%, OR=1.4, 95%CI=1.0-2.0).
Conclusions:
We present a simple tool for estimating the risk of adverse outcomes of acute stroke including death, disability at discharge, nosocomial infections, prolonged length of stay, as well as any joint care planning. CASH-0 indicates a low level and CASH-3 indicates a high level of risk of such complications after stroke.
