The time to innovate is now

Finding innovative ways to deliver health care has never been more important than it is today. How will an increasing number of people get quality care at a cost that the nation can afford? The answer isn't hard to figure out. It's innovation. Easier said than done, of course. Unlike many other industries, health care has remained highly fragmented, with a hierarchical culture resistant to change, and a payment system that rewards providers for quantity rather than quality of care. It has been slow to adopt technologies like electronic medical records that have the potential to make care more efficient and safer for patients. Even when new practices have been shown to improve care and reduce error, hospitals and doctors have been slow to adopt them.

You'll read of doctors, hospitals, insurers, researchers and cities that are all experimenting with novel methods to improve the quality, safety and effectiveness of care at a reasonable cost. Some are pioneering new delivery systems that encourage providers to coordinate patient care, rather than work at cross-purposes with little communication. Others are rigorously testing safety practices to determine how teams of caregivers can reduce adverse events and errors. Still others are mining medical records to identify patients who aren't taking their medications or might benefit from enrollment in a clinical trial.

And then there are all those attempts to give consumers the resources they need to stay healthier in the first place. That can mean things as simple as building more sidewalks and bike paths, or getting schools to bring back exercise at recess. Sometimes innovation means getting back to the basics.

Transplante inovador

Fonte: aqui.


Surgeons in Spain have carried out the world's first tissue-engineered whole organ transplant - using a windpipe made with the patient's own stem cells. The groundbreaking technology also means for the first time tissue transplants can be carried out without the need for anti-rejection drugs. Five months on the patient, 30-year-old mother-of-two Claudia Castillo, is in perfect health, The Lancet reports. She needed the transplant to save a lung after contracting tuberculosis. The disease had damaged her airways. Scientists from Bristol helped grow the cells for the transplant and the European team believes such tailor-made organs could become the norm. To make the new airway, the doctors took a donor windpipe, or trachea, from a patient who had recently died. Then they used strong chemicals and enzymes to wash away all of the cells from the donor trachea, leaving only a tissue scaffold made of the fibrous protein collagen. This gave them a structure to repopulate with cells from Ms Castillo herself, which could then be used in an operation to repair her damaged left bronchus - a branch of the windpipe. By using Ms Castillo's own cells the doctors were able to trick her body into thinking the donated trachea was part of it, thus avoiding rejection.
