Computer Scan Based Analysing System on Improving Stroke Management Quality Evaluation
Computer Scan Based Analysing System on Improving Stroke Management Quality Evaluation
Study is designed for two parts, a perspective, multi-center, historial control study and a
 randomized controlled study of acute ischemic stroke patients. For achieving the target of
 diagnosis and treatment KPI (Key performance indicator) of AIS patients and improving the
 defects of the traditional working mode, our center developed the medical records data
 acquisition and KPI statistics system based on computer scan. This method guarantees the
 authenticity of the data, It computes the KPI of the corresponding medical institutions in
 the corresponding period and gives feedback on a regular basis. Based on the KPI feedback
 system, a multifaceted quality improvement intervention is conducted in the intervention
 group hospitals. This study aims to explore whether this new working mode can continuously
 improve the overall KPI in Zhejiang province, and thus reflect the improvement of quality and
 standardization of medical service in AIS patients.
Study population:patients with acute ischemic stroke who were admitted to the hospital within
 7 days after the initial symptom onset.

 Program:

 There are multifaceted quality improvement interventions including:

 1. Implementation of standardized templates of medical record, evidence-based clinical
 pathway, and written care protocols.

 2. Feedback system of performance measures.

 3. Expert online consultation.

 Endpoints:

 Primary outcome:increase of diagnosis and treatment key performance indicator for acute
 ischemic stroke patients; Secondary outcome: the occurrence of ischemic stroke, total
 mortality, disability, and new clinical vascular events.
Inclusion Criteria:

 -  acute ischemic stroke or transient ischemic attacks patients

 Exclusion Criteria:

 -  patients who losing his medical record of having the incomplete medical record
