HARRISBURG, Pa. — BETSY came to Dr. Martin for a second — or rather, a sixth — opinion. Over a year, she had seen five other physicians for a “rapid heartbeat” and “feeling stressed.” After extensive testing, she had finally been referred for psychological counseling for an anxiety disorder.

The careful history Dr. Martin took revealed that Betsy was taking an over-the-counter weight loss product that contained ephedrine. (I have changed their names for privacy’s sake.) When she stopped taking the remedy, her symptoms also stopped. Asked why she hadn’t mentioned this information before, she said she’d “never been asked.” Until then, her providers would sooner order tests than take the time to talk with her about the problem.

Betsy’s case was fortunate; poor communication often has much worse consequences. A review of reports by the Joint Commission, a nonprofit that provides accreditation to health care organizations, found that communication failure (rather than a provider’s lack of technical skill) was at the root of over 70 percent of serious adverse health outcomes in hospitals.

A doctor’s ability to explain, listen and empathize has a profound impact on a patient’s care. Yet, as one survey found, two out of every three patients are discharged from the hospital without even knowing their diagnosis. Another study discovered that in over 60 percent of cases, patients misunderstood directions after a visit to their doctor’s office. And on average, physicians wait just 18 seconds before interrupting patients’ narratives of their symptoms. Evidently, we have a long way to go.
