This week Aetna launched an iPad-specific version of its iTriage app, which it acquired for an undisclosed sum last year. The iTriage app aims to help its users determine what medical condition they might have and where they might choose to go for treatment. More recently the app gave its users the ability to book appointments with select doctors right from their mobile devices.

Like most iOS apps, iTriage could be used previously on iPad devices, but previously the app did not leverage the entire screen. The full-fledged iTriage iPad app has a different layout and design, but its core feature set is the same as its smartphone iterations.

Some of those other iTriage features include a searchable database of thousands of medical symptoms, diseases, procedures and medications; maps and turn-by-turn directions to a comprehensive directory of health facilities; wait times for some emergency rooms; pre-registration for some ER departments; emergency hotlines and MD and nurse advice lines; and a personal health record (PHR) stored in Microsoft's HealthVault.

In March the app also added a search by ratings feature for healthcare facilities thanks to a partnership with Vitals.com.
