The VA recently announced that they will give out 1000 iPads to patients and caregivers in a pilot program to improve quality of care. The iPads will be reloaded with VA "apps" such as the VA patient portal. It allows patients to carry the iPad (and information in it) to physician visits outside of the VA network -- sort of "bringing your own medical records".
I think this approach makes a lot of sense for healthcare payors. It essentially provides a "personal" version of the HIE. With tablets only costing $500 a piece, it is a small cost compared with the overall disease management costs for patients. Now, we have to have a robust risk stratification model to identify the high risk / high cost patients that will most benefit from solutions like this!
