1 error per patient per day

The rate at which U.S. hospitals make mistakes with medication, according to the Institute of Medicine. Anybody who can find a way to reduce that by even a small fraction would save the medical system a lot of money and patients a lot of negative results. [Quartz]


The Chicago Blackhawks defeated the Tampa Bay Lightening last night 2-0 at home to win the Stanley Cup, prompting thousands across the United States to exclaim in one voice “Wait, seriously, hockey is still on? In June?” [ESPN]

4 percent growth

The promised cornerstone of a Jeb Bush presidency. Bush announced his bid for the GOP nomination on Monday, pledging a 4 percent annual economic growth rate. Get ready to hear that number a bunch. [POLITICO]

-35 percentage points

Donald Trump’s net favorability rating among Republicans, according to a new poll. Trump is, you know, the guy reportedly planning to run for president as a Republican. I’m certain his bid will go great. [Monmouth University]

175 stores

The Gap is struggling, and will shutter 175 stores and lay off 250 employees at its headquarters. Meanwhile, Old Navy — which Gap owns – is doing just dandy. [Quartz]

400 doctors per year

About 400 of Puerto Rico’s 11,000 doctors leave the territory every year, a major drain on the medical system. [The Washington Post]

35,000 government employees

India’s government is holding a Yoga Day this Sunday that may end up in the Guinness Book of World Records. About 35,000 government employees, students and other people are expected to participate. [The New York Times]

$1.7 billion

That was the revenue of Supercell — the Finnish studio behind mobile freemium game “Clash of Clans” — in 2014, up from $555 million the year before. Most of that money is derived from in-app purchases by its most devoted customers. (You know, like that “South Park” episode.) [ESPN]

$1.9 billion

CVS is buying Target’s pharmacy business, about 1,660 pharmacies which will continue to be operated within Target stores, for $1.9 billion. [Nasdaq]

$42 billion

The nation’s top heath insurers are kicking the tires on several mergers in order to stay competitive. UnitedHealth (the largest insurer) is trying to take over Aetna (the third-largest insurer) for somewhere in the neighborhood of $42 billion, and in response Anthem (the second-largest insurer) is trying to buy Cigna (the fifth-largest insurer). It’s all coming together as the equivalent of a paperwork-heavy summer camp movie ending. All this leaves Humana (the fourth-largest insurer) as the fifth wheel, or as I like to call it, the awesome unicycle who is doing just fine on his own thank you very much. [The Wall Street Journal]
