Introduction. Our aim was to assess the burden of total joint arthroplasties (TJA) performed for symptomatic hip and knee osteoarthritis (OA) in the Italian population. Methods. We analyzed national hospitalizations and Diagnosis Related Groups (DRG) databases to compute incidence, annual percent increase (APC), direct costs, and working days lost between 2001 and 2005 following TJA due to OA. Results. In year 2005, we recorded a total of 41,816 (APC:+5.4; 95%CI:5.1-5.8) and 44,051 (+13.4; 95%CI:13.1-13.8) hip and knee arthroplasties, respectively. Women represented the vast majority of patients undergoing TJA procedures (female/male ratio: 1.7 for hip and 2.9 for knee arthroplasties). When analyzing data by age groups, most of the patients were in the age groups of 65-74 and >75 years old, although the highest increases were observed <65 years of age. Revisions accounted for 6,387 (APC: +4.9; 95%CI: 4.0-5.7) and 2,295 (APC: +17.4; 95%CI: 15.7-19.2) procedures for hip and knee, respectively. Loss of working days in patients <65 was estimated between 805,000 and 1 million days. Hospital costs increased from 741 million to 1 billion Euros over the 5-year period (412 to 538 million for hip and 329 to 517 million for knee arthroplasties). Rehabilitation costs increased from 229 to 323 million Euros. Post-operative complications were estimated between 3.1 and 4.5 million Euros, with average cost per patient being 16,835 and 15,358 euros for hip and knee arthroplasty, respectively. Conclusion. Socio-economic burden of TJA performed for symptomatic osteoarthritis in Italy is remarkable and calls for the adoption of proper preventive measures. © 2012 by the American College of Rheumatology.

Abstract

Introduction. Our aim was to assess the burden of total joint arthroplasties (TJA) performed for symptomatic hip and knee osteoarthritis (OA) in the Italian population. Methods. We analyzed national hospitalizations and Diagnosis Related Groups (DRG) databases to compute incidence, annual percent increase (APC), direct costs, and working days lost between 2001 and 2005 following TJA due to OA. Results. In year 2005, we recorded a total of 41,816 (APC:+5.4; 95%CI:5.1-5.8) and 44,051 (+13.4; 95%CI:13.1-13.8) hip and knee arthroplasties, respectively. Women represented the vast majority of patients undergoing TJA procedures (female/male ratio: 1.7 for hip and 2.9 for knee arthroplasties). When analyzing data by age groups, most of the patients were in the age groups of 65-74 and >75 years old, although the highest increases were observed <65 years of age. Revisions accounted for 6,387 (APC: +4.9; 95%CI: 4.0-5.7) and 2,295 (APC: +17.4; 95%CI: 15.7-19.2) procedures for hip and knee, respectively. Loss of working days in patients <65 was estimated between 805,000 and 1 million days. Hospital costs increased from 741 million to 1 billion Euros over the 5-year period (412 to 538 million for hip and 329 to 517 million for knee arthroplasties). Rehabilitation costs increased from 229 to 323 million Euros. Post-operative complications were estimated between 3.1 and 4.5 million Euros, with average cost per patient being 16,835 and 15,358 euros for hip and knee arthroplasty, respectively. Conclusion. Socio-economic burden of TJA performed for symptomatic osteoarthritis in Italy is remarkable and calls for the adoption of proper preventive measures. © 2012 by the American College of Rheumatology.
