Medicare: Trends in Beneficiaries Served and Hospital Resources Used in Implantable Medical Device Procedures

Results from a U.S. government agency report summarize data on average length of stay, patient characteristics, discharges, etc. Highlights include:

  • In the U.S. in 2009, knee, hip and shoulder replacement and lumbar fusion procedures accounted for 98% of Medicare's orthopaedic implantable device expenditures.
     
  • Between 2003 and 2009, admission rates for knee replacement rose at an average annual increase of 6.7%; for hips, 4.1%; for shoulder replacement, 20.1% and for lumbar fusion, 11%. During that time, the proportion of lumbar fusions performed with a bone morphogenetic protein increased from ~7% to 40% of all lumbar fusions.
     
  • Average length of stay for orthopaedic implant recipients decreased between 2003 and 2009 for beneficiaries in all reported health status groups. For instance, LoS for knee replacement fell 2.8% per year, representing a reduction of 64 days per 100 hospital admissions.
     
  • From 2004 to 2009, Medicare hospital expenditures related to orthopaedic implantable medical devices increased 8.1% per year.
