The CDC’s National Center for Health Statistics released data this month from the National Hospital Discharge Survey on hip replacements from 2000-2010. The data looks at the total number of hip replacements, the age distribution and rate of hip replacements in patients over 45, and average length of stay. Key findings:

– In 2010, 310,800 total hip replacements were performed among inpatients aged 45 and over.

– The number and rate of total hip replacements among inpatients aged 45 and over increased from 2000 to 2010: from 138,700 to 310,800 in number and from a rate of 142.2 to 257.0 per 100,000 population.

– The age distribution of inpatients aged 45 and over who received total hip replacements changed significantly between 2000 and 2010, with the percentage of total hip replacements increasing for younger age groups and decreasing for older age groups.

– The average length of stay after total hip replacement among inpatients aged 45 and over decreased from 2000 to 2010, from nearly 5 days to just under 4 days.
