Have you noticed lately how your doctor carries around a little PDA to record notes about your condition and e-mail prescriptions to your pharmacy? The medical technology company Medcryption is following suit with the launch of its new VitalChart Secure Personal Health Record, a secure, digital personal health record that you carry with you on your keychain. Not only can you easily communicate tricky medical conditions to new doctors with this handy device, but you may be able to skip the forms and simply pass your VitalChart over the desk for downloading! Here’s how it works: A Web site collects your personal information, which is transcribed and downloaded to a portable and waterproof (!) USB key drive. If your provider is a member of the VitalChart network, she can even verify and add info electronically. $95 a year at vitalchart.com.
