A third of patients with chronic conditions who exchanged secure emails with their doctors said that the communications improved their overall health, according to a study conducted by one of US' largst healthcare providers, Kaiser Permanente.
"We found that a large proportion of patients used email as their first method of contacting healthcare providers across a variety of health-related concerns," said the study's lead author Mary E. Reed, staff scientist with the Kaiser Permanente research division.
Researchers surveyed 1,041 Kaiser Permanente patients in Northern California who had chronic conditions such as asthma, coronary artery disease, congestive heart failure, diabetes or hypertension.
Virtually all patients with chronic conditions said that exchanging email with their health care provider either improved (32 percent) or did not change their overall health (67 percent).
Less than one percent said that emailing made their health worse.
More than half of respondents (56 percent) had sent their provider an email within the previous year, and 46 percent used email as the first method of contact for one or more medical concerns.
