Roughly 3.4 million emergency department visits - an average of 9,400 a day - were specifically for back problems at U.S. hospitals in 2008, according to the latest News and Numbers from the Agency for Healthcare Research and Quality.
In the same year, there were over 663,000 inpatient stays - a daily average of nearly 1,820 - principally for back surgery or other back disorder treatments.
AHRQ also found that in 2008:
• Adults ages 18 to 44 were the most likely to require just emergency department care for back pain (1,569 visits per 100,000 people) and seniors ages 65 to 84 were the least likely (1,084 visits per 100,000 people).
• However, people ages 18 to 44 years were far less likely to be hospitalized while seniors ages 65 to 84 years had the highest rates of hospitalization (130 hospital stays per 100,000 people versus 607 per 100,000 people).
• Men were less likely than women to need emergency department care or be hospitalized for back pain (1,005 visits and 209 admissions per 100,000 men versus 1,244 emergency visits and 225 admissions per 100,000 women).
• The overall costs for inpatient stays principally for back problems was over $9.5 billion, making it the 9th most expensive condition treated in US hospitals.
