Assessment of rehabilitation following acute ischaemic stroke in China: a registry-based retrospective observational study

Objectives This study aimed to describe the frequency, determinants and outcomes for assessment of patients who had an acute ischaemic stroke (AIS) for rehabilitation during hospitalisation in China.Design A registry-based retrospective observational study.Study design and settings Data regarding assessment or rehabilitation were extracted from the Chinese Stroke Center Alliance database from 1 August 2015 to 31 July 2019. Univariate and multivariate analyses were conducted to identify patient and hospital characteristics associated with rehabilitation assessment during acute hospitalisation as well as discharge outcomes.Study cohort We included 837 897 patients who had a stroke in this study with patient characteristics, admission location, medical history, hospital characteristics and hospital designation.Primary and secondary outcome measures Rehabilitation assessment and discharge outcomes.Results Among 837 897 patients who had a stroke admitted to 1473 hospitals, 615 991 (73.5%) underwent rehabilitation assessment. There were significant variations in the rates of rehabilitation assessment across hospitals (IQR 61.3% vs 92.9%). According to multivariate analysis, guideline recommended care delivery was associated with a higher rehabilitation assessment rate, whereas high/low body mass index, ambulation (OR 0.88; 95% CI 0.87 to 0.90), history of stroke (OR 0.94; 95% CI 0.93 to 0.95), coronary heart disease (OR 0.84; 95% CI 0.82 to 0.85) and atrial fibrillation (OR 0.91; 95% CI 0.89 to 0.94) were associated with a lower rate. Additionally, rehabilitation assessment during hospitalisation was significantly associated with lower in-hospital mortality (OR 0.38; 95% CI 0.35 to 0.41) and a higher probability of discharge to a rehabilitation centre (OR 2.66; 95% CI 2.5 to 2.82).Conclusions Nearly one-quarter of patients who had an AIS do not undergo documented rehabilitation assessment and compliance across hospitals varies. Thus, it is necessary to improve adherence to rehabilitation assessment to improve the quality of medical care for patients who had an AIS.
