Another hospital quality scorecard seems to appear nearly every month these days, and Wednesday's release of the Joint Commission's "Top Performers" is right on schedule for September.
In March, it was HealthGrades' 50/100 hospitals list and in April, Thomson Reuters released its top 100. June ushered the Leapfrog Group's Safety Scores. And in July, Consumer Reports and U.S. News & World Report published their all-star lineups weeks apart.

And in late July, the Centers for Medicare & Medicaid Services uploaded to the Hospital Compare website a massive three-year data update for dozens of measures including 30-day readmissions and value-based purchasing scores.
Each of these groups uses different —though sometimes overlapping and often contradictory—criteria, thresholds, and weighted algorithms. It's enough to make you dizzy.
