Must-have functions in clinical application

Doctors see clinical software as a tool to help them sort out lots of problems where a team of workers would achieve in the past. What functions of a killer application would be desired by GPs? I looked around and find a useful comment from an article online.

How family doctor can function without these features:

• chronic prescription handling
• drug interaction checking
• drug information
• patient information leaflets
• printing useful patient data report
• tracking of investigations
• chronic disease management tools/searches
• audit tools for doctors (i.e., to ensure they are doing what they think they are doing)
• legible notes
• comprehensive backup strategies
• remote access from home

An open source tool like OSCAR seems to be popular among the GPs. That's good starting point to add and enhance such features for making doctors' life easier.
