Top 100 reasons for emergency room visits
Casual viewers of prime-time television programs like "Grey's Anatomy" or "The Resident" might be forgiven for thinking their local ER is loaded with victims of car crashes, explosions, and other dramatic events on a daily basis. The reality, however, is a little more mundane. While emergency rooms across the country certainly deal with all manner of serious conditions, the fact is quite a few of the patients who come into the ER are there for relatively minor, non-life-threatening reasons.
Stacker analyzed data from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project to determine the 100 most common reasons for emergency room visits in the United States. The data, which was last updated in 2014, gives some fascinating insight into ER usage in America. Some visits, like those for sprains or fatigue, were non-emergent (a growing problem in American medical care). Others were for much more serious conditions. Think you can guess the top 10? Read on to see the full list—no spoilers, but we bet our #1 isn't what you think it is!
