Background

The ischemic Stroke risk score is a validated prognostic score which can be used by clinicians to estimate patient outcomes after the occurrence of an acute ischemic stroke.

Aim

In this study, we examined the association between the ischemic Stroke risk score and patients' 30-day, one-year, and two-year healthcare costs from the perspective of a third party healthcare payer.

Methods

Patients who had an acute ischemic stroke were identified from the Registry of Canadian Stroke Network. The 30-day ischemic Stroke risk score prognostic score was determined for each patient. Direct healthcare costs at each time point were determined using administrative databases in the province of Ontario. Unadjusted mean and the impact of a 10-point increase ischemic Stroke risk score and a patient's risk of death or disability on total cost were determined.

Results

There were 12 686 patients eligible for the study. Total unadjusted mean costs were greatest among patients at high risk. When adjusting for patient characteristics, a 10-point increase in the ischemic Stroke risk score was associated with 8%, 7%, and 4% increase in total costs at 30 days, one-year, and two-years. The same increase was found to impact patients at low, medium, and high risk differently. When adjusting for patient characteristics, patients in the high-risk group had the highest total costs at 30 days, while patients at medium risk had the highest costs at both one and two-years.

Conclusions

The ischemic Stroke risk score can be useful as a predictor of healthcare utilization and costs early after hospitalization for an acute ischemic stroke.

Iscore预测急性缺血性中风住院后早期的总医疗费用

背景

缺血性中风风险评分是经过验证的预后评分，临床医生可以使用它来评估急性缺血性中风发生后的患者预后。

目的

在这项研究中，我们从第三方医疗保健付款人的角度研究了缺血性中风风险评分与患者30天，一年和两年的医疗保健费用之间的关系。

方法

从加拿大中风网络注册处确定患有急性缺血性中风的患者。确定每位患者的30天缺血性卒中风险评分的预后评分。使用安大略省的行政数据库确定每个时间点的直接医疗费用。确定了未调整的均值以及缺血性卒中风险增加10点以及患者死亡或残疾风险对总成本的影响。

结果

有12 686例患者符合研究条件。在高风险患者中，总的未调整平均成本最大。调整患者特征后，缺血性卒中风险评分增加10分会分别导致30天，一年和两年的总费用增加8％，7％和4％。发现相同的增加对低，中和高风险患者的影响不同。在调整患者特征后，高风险组的患者在30天的总费用最高，而中度风险的患者在一年和两年的费用最高。

结论

缺血性卒中风险评分可作为急性缺血性卒中住院后早期医疗保健利用和费用的预测指标。
