  • Title: Economic burden of periprosthetic joint infection in the United States.
    Author: Kurtz SM, Lau E, Watson H, Schmier JK, Parvizi J.
    Journal: J Arthroplasty; 2012 Sep; 27(8 Suppl):61-5.e1. PubMed ID: 22554729.
    Abstract:
    This study characterizes the patient and clinical factors influencing the economic burden of periprosthetic joint infection (PJI) in the United States. The 2001-2009 Nationwide Inpatient Sample was used to identify total hip and knee arthroplasties using International Classification of Diseases, Ninth Revision, procedure codes. The relative incidence of PJI ranged between 2.0% and 2.4% of total hip arthroplasties and total knee arthroplasties and increased over time. The mean cost to treat hip PJIs was $5965 greater than the mean cost for knee PJIs. The annual cost of infected revisions to US hospitals increased from $320 million to $566 million during the study period and was projected to exceed $1.62 billion by 2020. As the demand for joint arthroplasty is expected to increase substantially over the coming decade, so too will the economic burden of prosthetic infections.
