Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke (ANGEL-ACT): Phase Two (ANGEL-ACT II)
Work Flow Improvement in Pre-procedural Management of Acute Ischemic Stroke With Endovascular Treatment: a Multi-centre, Cluster Randomised, Open Label, Parallel Controlled Study
The study is the second phase of Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke (ANGEL-ACT).
During the first phase of the ANGEL-ACT (NCT03370939, a prospective multi-center registry study), problems and difficulties in the emergency work flow of acute ischemic stroke care in China have been identified, such as inadequate pre-hospital notification, delay of in-hospital diagnosis and treatment, difficulty in treatment consent, lack of professional training of endovascular treatment,etc., especially in the delay of in-hospital diagnosis and treatment.
ANGEL-ACT II is a cluster randomized, parallel controlled study. The aim of this study was to evaluate the effectiveness of multi-modal medical quality improvement measures on the delay of hospital-level emergency work flow of acute ischemic stroke management as well as its impact on patient prognosis. The interventional measures include emergency work flow management app on smartphone, specialized training, assessment of quality improvement outcomes and feedback on a regular basis.

Intervention / Treatment |
---|---|
EXPERIMENTAL: Interventional Site
The process below will be allocated in Interventional Sites:
|
The interventional measures include emergency work flow management app on smartphone, specialized training, assessment of quality improvement outcomes and feedback on a regular basis, patient-centred management frame based lean six-sigma, and other specialised approach.
|
NO_INTERVENTION: Control Site
The control site would not undergo any emergency work flow modification for acute ischemic stroke patients who eligible for endovascular treatment.

Modified Rankin Scale independence rate within 90 days after the procedure

The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability.
(Score Description: 0---No symptoms at all.
1---No significant disability despite symptoms; able to carry out all usual duties and activities.
2---Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance.
3---Moderate disability; requiring some help, but able to walk without assistance.
4--- Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance.
5---Severe disability; bedridden, incontinent and requiring constant nursing care and attention.
6---Dead.
In clinical practice, mRS ≤ 2 means good outcome.
Modified Rankin Scale independence rate refers to the percentage of participants with mRS less than 3 after treatment.

EQ-5D-3L 90 days after the procedure
Time Frame: 90 days after the procedure
|
The EQ-5D-3L essentially consists of two pages: the EQ-5D descriptive system and the EQ-5D visual analogue scale (EQ VAS).
The EQ-5D-3L descriptive system comprises the following five dimensions, each describing a different aspect of health: MOBILITY, SELF-CARE, USUAL ACTIVITIES, PAIN / DISCOMFORT and ANXIETY / DEPRESSION.
Each dimension has three levels: no problems, some problems, extreme problems (labelled 1-3).
The respondent is asked to indicate his / her health state by checking the box against the most appropriate statement in each of the five dimensions.
The EQ VAS records the respondent's self-rated health on a vertical VAS where the endpoints are labelled 'The best health you can imagine'( score as 100) and 'The worst health you can imagine' (score as 0).
This information can be used as a quantitative measure of health outcome as judged by the individual respondents.
