Physicians and hospitals aren't the only ones using mobile devices and smartphone apps. Consumers are using them to manage their own health and wellness. Approximately 500 million smartphone users worldwide will use a health-care app by 2015, according to mobile research specialists Research2Guidance.

Locally, Mount Carmel Health System, Nationwide Children's Hospital, OhioHealth and the Ohio State University Medical Center all have Web-based portals for patients.

Patients using the My Mount Carmel app can complete a personal profile, schedule a screening mammogram, pre-register for a hospital stay and pay their bill. More functionality is scheduled for 2012.

A Nationwide Children's app offers quick links to services and locations.

OhioHealth's app focuses on women's health and uses personalized, patient-oriented education. Over the next six months, the app will expand to include orthopedics, physical therapy and cardiology.

More than 21,000 patients use OSUMC's OSUMyChart to access test results, request prescription refills, view clinic visits and communicate with their providers.
