Hospitals can get overwhelmed by the array of ratings, rankings and scorecards that gauge the quality of care that they provide. Yet when those reports come out, we still scrutinize them, seeking to understand how to improve. This work is only worthwhile, of course, when these rankings are based on valid measures.
Certainly, few rankings receive as much attention as U.S. News & World Report’s annual Best Hospitals list. This year, as we pored over the data, we made a startling discovery: As a whole, Maryland hospitals performed significantly worse on a patient safety metric that counts toward 10 percent of a hospital’s overall score. Just three percent of the state’s hospitals received the highest U.S. News score in patient safety — 5 out of 5 — compared to 12 percent of the remaining U.S. hospitals. Similarly, nearly 68 percent of Maryland hospitals, including The Johns Hopkins Hospital, received the worst possible mark — 1 out of 5 — while nationally just 21 percent did. This had been a trend for a few years.
