Prediction of Ischemic Stroke Recurrence Based on COX Proportional Risk Regression Model and Evaluation of the Effectiveness of Patient Intensive Care Interventions

Abstract

With the continuous improvement of medical technology and the aging of the population, the death rate of stroke is gradually decreasing, but the recurrence rate is still high, and the number of recurrences is increasing, resulting in disability and other symptoms, which brings great burden and distress to patients and their families. As the number of strokes increases, neurological impairment becomes more and more severe, affecting patients’ ability to live, socialize, and work, and seriously reducing their quality of life. Clustered care is a combination of evidence-based linked interventions and a multidisciplinary team providing the best possible care through evidence-based research and highly operational practice, and it can improve outcomes for ischemic stroke patients more than implementation alone. This paper presents a Cox proportional risk regression-based model, using it to build the most used semi-parametric model for multifactorial survival analysis, due to its advantages of both parametric and nonparametric models, and to analyze the factors influencing survival time in study subjects with incomplete data. The proposed strategy has been found to be useful in predicting ischemic stroke recurrence and cluster care interventions for patients.

Characteristics of risk factors for ischemic stroke recurrence and death in Western China: a retrospective study

“…Apart from the main causes of stroke and existing pathological state, the incidence of stroke and mortality in patients can be signi cantly reduced after taking corresponding secondary prevention measures 11 . Previous studies have also shown that the analysis of clinical history and laboratory data can accurately predict the adverse outcomes of patients who had experienced an IS, and clinical intervention programs for high-risk factors are also practical and effective [12][13][14] . Nearly 20% of the patients in the Chinese community (i.e., this study's population) die within ve years after their rst stroke, and more than 40% relapse within ve years of an IS 15 .…”
