Disease Trend Ranking in MDV Data (2021)

1. What Kind of Information is included in MDV Database?

MDV database contains medical treatment, disease, and partial blood test results information allowing different analyses by pharmaceutical companies, medical device manufacturers, academia, research institutions, and health insurance companies.
Within the disease information, data such as ICD10 (International Classification of Diseases 10th Edition (2013)) codes and names are available enabling quick analysis of target patient population based on disease definition.

Despite the fact that MDV Database collects the data from advanced/acute care denominated hospitals, we can clearly observe that the list of most frequently reported diseases also contains chronic conditions seen in outpatient setting.
