Different studies showed large variation between care processes in multiple diseases, which lead to large variation in outcomes. Better adherence to evidence-based guidelines for these diseases can reduce this variation and can improve the health outcomes. Since international studies have demonstrated wide variations in care processes for acute stroke, it would be interesting to repeat these investigations in the population of stroke patients. Worldwide, stroke is a leading cause of disability and death. Every two seconds, someone across the world experiences a symptomatic stroke. 50% of stroke survivors has moderate to severe neurologic deficits, 25% of them depend on others. In Belgium, stroke is one of the most important causes of invalidity. Every year approximately 18 000 people in Belgium experiences a stroke, which results in almost one person every two hours, with a mortality rate of 30%. The world health organization has the ambition to significantly reduce the mortality and risk factors for non-communicable diseases by 2025. The mortality and disability in stroke patients can be reduced by organized stroke care, which includes effective strategies in stroke management, treatment and prevention. Also, other health domains, like functional recovery, healthcare costs and patient satisfaction, were positively related to adherence on stroke guidelines. This evidence had been converted in several clinical guidelines for stroke care. However, the adherence to these guidelines is variable. As already mentioned before, international studies have demonstrated wide variations in care processes for acute stroke. However, a positive relationship has been shown between the implementation of evidence-based clinical guidelines and the quality of stroke care. Therefore, it is important to both implement these guidelines and to improve the adherence to them.

The aim of this study is to map the variation in stroke care in Flemish hospitals and to get an overview about the variation within and between these hospitals. During this study, electronic patient records will be analyzed to check which interventions are performed in a specific patient and of which no information could be found in de patient record.
