They do it fir the hospital/provider conglomerates, too. The company gets money for providing proof that they have done a certain percentage of things like 'depression screenings' (ie rx ssri for saying you feel bad today), hypertension screenings (gotta get you on the latest BP drug) or offered referrals for gov services, etc. If a certain percentage of the patients are vaxxed etc more money. They try to make it sound like they are being proactive and a lot of doctors are too dumb to see the manipulation. Plus under a big company if you are a statistical outlier you will be punished or fired or not get your incentive checks.
