NEW YORK, Nov 21: People who had access to their medical records online also came into their doctor’s office for more appointments and used the emergency room more often than those who didn’t log on, in a new study from Colorado. One theory supporting online access to health records is that if patients can look up their test results and put in for prescription refills online, they’ll make fewer unnecessary trips or calls to the office. That would save both patients and the health system time and money. (agencies)
