1. What Kind of Information is included in MDV Database?
MDV database contains medical treatment, disease, and partial blood test result information allowing different analyses by pharmaceutical companies, medical device manufacturers, academia, research institutions, and health insurance companies.
Within the medical treatment information, medications are included. Medication information can be broken down to generic names and product names. This information can be used to target a specific patient population for refined analysis.
On this occasion, we will look at the medication trend ranking in Japan using the data in MDV database.
