I totally agree, transparency has the power to really move the needle. The issue I see though is that all parties that have data are incentivized to keep it to themselves. Many "leading" hospitals actually don't have super great quality compared to other, less well known hospitals. So powerful, well known but low quality hospitals will lose if there's more transparency. They know this, and they're fighting it Large EMRs will also lose if there is more interoperability. Right now the fact that Epic and Cerner "own" a hospitals data gives them a lot of power. If anyone wants data, they have to go not just through the hospital, but through the EMR duopoly. Insurers don't want to publish their rates, because they'd face backlash from all around when people realize how much variability there is in how much they pay for the same procedure at different hospitals
