Basic countermeasures solve.

Death rates from bacterial infections dropped over 90% from historic levels before the introduction of penicillin. Sanitation and vaccines are far more effective methods to control bacterial infections than antibiotics ever were or ever will be. Boring old soap and water, filtration, bleach, and alcohol kill superbugs just fine. None of these things are in short supply.
The acquisition of multiple drug resistances generally (but not always) causes bacteria to become a bit less fit and unable to infect otherwise healthy adults. The victim of this particular superbug was in her seventies and had been in and out of hospitals for over a year. This is a fairly typical profile for victims of multi-drug resistant bacteria.
The worst-case scenario, if we continue to abuse and overuse antibiotics in feedlots and hospitals, is that these bugs will pick up compensatory mutations and become more virulent. Many fairly routine procedures - chemotherapy, thoracic and orthopedic surgery - will become much more risky.
But the risk will still be largely confined to hospitalized patients. MDR bacteria are extremely unlikely to cause a global pandemic on the scale of the 1919 influenza or AIDS epidemics, so long as we continue to provide clean food and water to the public.
