“On CrowdMed, a new service that brings doctors — many of them retirees with years of experience and wisdom — together with laypeople to crowdsource difficult diagnoses, users post their symptoms and their case is ‘live’ for 30 days. During this time, the site’s ‘medical detectives’ — all volunteers — offer possible diagnoses, discuss with each other, ask questions of the patient and ultimately bet points on the right diagnosis from the suggestions offered by their peers. At month’s end, CrowdMed sends the diagnoses with the most points to the user, who can then discuss the results with his or her doctors. Patients can incentivize the team’s medical detectives by offering a cash stipend.”
