Abstract
With the ever increasing rate of total hip replacement and life span of these patients, there has been an upward trend towards the incidence of peri-prosthetic fractures. Previous studies does suggest the implant cost to as high as 30% of the total reimbursement in primary hip arthroplasty but this figure is much higher in periprosthetic fractures where long stem revisions are commonly used
A prospective comparative study analyzing the total cost of hospital stay for a cohort of 52 consecutive patients with peri-prosthetic fractures of long bones treated in two hospitals from October 2007 to march 2009 was conducted. Demographic data, fracture classification and method of surgical treatment along with the length of hospital stay were recorded in detail. The total cost calculated was then compared to the range of reimbursement price based on HRG (human Resource Group) coding. The implant cost was determined from the buying cost by each institution.
52 patients were available for review. Average age of the patients operated was 78.5 years. 69 percent of the peri-prosthetic fractures in our series were around the proximal femur. The average cost of stay was £ 16453 (£ 1425- 26345). The reimbursement to the hospital ranged from £ 1983 to £ 8735.
Hospital source utilization for peri prosthetic fractures is quite high compared to the reimbursement being given to hospitals for treating such patients. This can be as low as £ 1500 as acute phase tariff to £ 9100 for elective revisions and the implant cost can vary from 50% to 200% of the total reimbursement cost. Current recording system for peri-prosthetic fracture is unclear resulting in discrepancy between resource utilization and reimbursement thus resulting in substantial financial losses for hospitals that perform these procedures.
