ABSTRACT
OBJECTIVES:
Various measures are used to improve the quality of stroke care. In Germany, these include concentrating treatment in specialized facilities (stroke units), mandatory quality comparisons of hospitals in some German states, and treatment according to prespecified structure and process specifications (neurological complex treatment 8-981 or 8-98b). These measures have previously only been analyzed individually and regarding short-term patient outcomes. This study analyzes these measures in combination, considering patients' comorbidities as well as stroke severity in a longitudinal perspective. MATERIALS/METHODS:
Analyses were based on data from 243,415 insurees of Germany's biggest health insurance (AOK) admitted to hospitals between 2007 and 2017 with cerebral infarction. Mortality risk was calculated using Cox regressions adjusted for various covariates. Kaplan-Meier analyses were differentiated by treatment site (stroke unit/external quality assurance/ Federal State Consortium of Quality Assurance Hesse - LAGQH) were performed, followed by log-rank tests and p-value adjustment. Trend analyses were performed for treatment types in combination with treatment sites.RESULTS:
All analyses showed significant advantages for patients who received Neurological Complex Treatment, especially when the treatment was performed under external quality assurance conditions and/or in stroke units. There was an increasing frequency of specialized stroke treatment.CONCLUSIONS:
Quality-enhancing structures and processes are associated with a lower mortality risk after stroke. There appears to be evidence of a cascading benefit from the implementation of neurological complex treatment, external quality assurance, and ultimately, stroke units. Consecutively, care should be concentrated in hospitals that meet these specifications. However, since measures are often applied in combination, it remains unclear which specific measures are crucial for patient outcome.Key words
