Perhaps you should try some spelling variations:
disease management » database management
decentralized mas » decentralized case, decentralized mean, decentralized aaa
mas management » emas management, mass management, das management

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: "((\"decentralized ((case management) OR (disease management))\") or (\"decentralized mas management\"))".
• Removing quotes may allow a broader search: (( decentralized ((case management) or (disease management)) ) or ( decentralized mas management )).
