Patients who bring a companion to their doctor's visits report a better, more informative experience.

Researchers at Johns Hopkins University reviewed surveys filled out by over 12,000 medicare beneficiaries.

They found close to 40 percent of participants were regularly accompanied by spouses or children to their doctor's visits.

Those who had a companion were more satisfied with their doctor's skills and communication, and reported a better experience overall.

Over 60 percent of companions helped with communication, and in most cases, were in better health than the patient.
