We spend a lot of time talking about how hard it is for patients to find out how much any particular health care service is going to cost them.

A bigger problem: The Wall Street Journal uses the example of knee replacements to illustrate that difficulty, but also raises a bigger, even more frustrating point: It’s hard for hospitals to figure out how much their own work costs.

The details: Gundersen Health System in Wisconsin “had no real idea what it cost to perform the surgery” and wanted to find out why it was charging a list price north of $50,000, WSJ reports.

  • That process entailed “an 18-month review” in which “an efficiency expert trailed doctors and nurses to record every minute of activity.”
  • They ultimately determined that the procedure cost $10,550 — a fifth of the price the hospital had set.
  • The review uncovered other quality and efficiency issues. Some days, there weren’t enough beds for patients after surgery, and doctors performed the procedure differently “for reasons that weren’t always clear.”
  • “Gundersen’s analysis found that the hospital had been exclusively using brand-name cement, premixed with antibiotics. The hospital slashed its cement costs by 57% by switching to a generic,” per WSJ. “It isn’t clear how the orthopedics department came to use the brand-name cement … [one doctor] said he was perplexed when the analysis uncovered it.”

My thought bubble: Good on Gundersen for trying to figure all this out, but Gundersen isn’t an isolated example. This is the system we have.

  • And even though most of us don’t pay the full sticker price for health care, our premiums and out-of-pocket costs all still flow from that top-line number — which, WSJ notes, is set “using a combination of educated guesswork and a canny assessment of market opportunity.”

Trump tightens screws on ByteDance to sell Tiktok

President Trump added more pressure Friday night on China-based TikTok parent ByteDance to exit the U.S., ordering it to divest all assets related to the U.S. operation of TikTok within 90 days.

Between the lines: The order means ByteDance must be wholly disentangled from TikTok in the U.S. by November. Trump had previously ordered TikTok banned if ByteDance hadn't struck a deal within 45 days. The new order likely means ByteDance has just another 45 days after that to fully close the deal, one White House source told Axios.

In her first sit-down interview since being named Joe Biden's running mate, Sen. Kamala Harris talked about what she'll do to fight for women if elected VP, and how the Democrats are thinking about voter turnout strategies ahead of November.

What they're saying: "In a Biden-Harris administration women are going to be a priority, understanding that women have many priorities and all of them must be acknowledged," Harris told The 19th*'s Errin Haines-Whack.
