Angioplasty Declining, Helped or Harmed?

As Angioplasty Declines, this is Helped or Harmed for Patients?this is a quistion for many people,because it is associated with human's health.
from the reporting of hospitals’ mortality data can be a healthy way to boost quality of care.That’s the crux of the dilemma at Massachusetts General Hospital in Boston and Saint Vincent Hospital in Worcester, Mass., which have had higher-than-average death rates in patients undergoing angioplasty, a procedure in which stents are placed into the arteries to open them up. Here’s the story in the Boston Globe.
Mass General has acknowledged performing the procedure on “a relatively large number of patients with little hope of survival,” and has cut down on using it in some very sick patients, such as those with advanced cancer who could die within weeks, the Globe reports. But the risk is that some patients who should get the procedure will now be overlooked, as hospitals try to avoid ugly mortality numbers in the future.
But it can also have a side effect: discouraging hospitals from taking on the toughest cases for fear that failure will bring bad publicity.
