Final answer:
The incorrect statement regarding stroke databases is that certification requires Microsoft Excel; database content can vary widely and they may be homegrown or external, with benchmarking being an advantage of external databases.
Step-by-step explanation:
The statement that 'Stroke center certification requires the use of Microsoft Excel for databases' is not true of stroke databases. Stroke databases can vary in content, potentially including just a few data points or hundreds, depending on the scope and purpose of the database. These databases may be custom-developed ('homegrown') by the institution or purchased from external vendors. The key advantage of external stroke databases often cited is the ability to benchmark patient outcomes against others across various institutions, helping to identify areas for improvement in stroke care.
