Mayor Bill de Blasio says that “universal health care” is one of the local issues he’ll focus on now that he’s given up on his White House run. He’s got his work cut out for him.

The latest Mayor’s Management Report shows enrollment in MetroPlus, the city’s health plan for low-income people on Medicaid and Medicare, fell 3,000 members to 519,000 in the latest fiscal year. Yet, according to NYC Health + Hospitals, applications are up 15 percent.

And overall visits to the city’s 11 hospitals dropped to about 1 million people from 1.1 million the previous year. Patient satisfaction ratings slumped to 80.7 percent from 85.3 percent the year before — after climbing from 81 percent in 2014.

The Post’s Julia Marsh noted that city hospitals also received poor marks for women’s health. Fewer women received mammogram screenings while fewer expectant mothers got prenatal care.

Overall, H+H saw $240 million in added revenue — but $354 million in new spending, thanks in part to a higher staff head count.

Which brings us to the advent of “universal” care. De Blasio announced his plan to cover 300,000 uninsured New Yorkers in January, but the NYC Care Card launched only last month.

True: City hospitals and clients couldn’t turn away indigent patients even before that. But the point of the program is to get these people the health care they need but had been avoiding.

If the mayor means to be hands-on about universal care, he’d best start figuring out how to provide it when the city hospital system is already struggling.
