McKinsey remains the top consulting firm in the field, but the competition is gaining ground. While losing a point over the previous year is hardly fatal to McKinsey, it comes at a time when BCG added 2 points -- a 3 point swing that bears watching. At the same time, GE Healthcare and Deloitte also saw their mindshare jump by 3.5 points each. That's certainly a positive sign as healthcare providers are increasingly turning to consulting firms to better get a grip on COVID-19.
