Only about a third of health care providers use mobile and remote technologies in their work, leaving many struggling to coordinate care among themselves and their patients, a new survey finds. Clinicians report that they feel hindered by old or underused technologies, wasted exchanges and concerns about privacy and security. Among respondents, 69 percent reported that patient care is often delayed while waiting for important medical records. Despite this, nearly all doctors say they do value the effect that improved communication could have on managing population health and say strong collaboration can result in reduced readmissions.
