She adds that the hospitals were rated based on their performance on "national evidence-based process of care "accountability" measures that the hospitals chose to report."
In an interview, Sharon Springer, the organization's director of external measurement relations, adds that "it's heartening to the Joint Commission to see that hospitals continue to improve, and that we have more top performers. But one of the things we find really heartening is the fact that we had 244 hospitals that achieved 'Top Performer' status for two consecutive years. That really speaks to the fact that these organizations are able to sustain that performance, and that's key."
The hospitals were evaluated based on how they scored in 43 performance measures they chose to report within eight categories. This is twenty measures and four categories more than were considered last year.
The JC evaluated how hospitals provided care for patients with heart attack, heart failure, pneumonia, or childhood asthma, or who needed psychiatric services, or underwent surgery. The Joint Commission also evaluated how well hospitals implemented measures designed to prevent stroke or venous thromboembolism from occurring.
