Brendan McDermid/Reuters Healthcare professionals surveyed by venture capital firm Venrock are skeptical about the new healthcare venture JPMorgan, Amazon, and Berkshire Hathaway have formed. Of the 300 people surveyed, 73% expected it to take longer than expected, with 25% saying the companies "have no idea what they're getting into." There have been relatively few details about the venture and what it looks like, but the news alone sent healthcare stocks plummeting in January after it was announced.
