Implant standardization for hemiarthroplasty: implementation of a pricing matrix system at a level II community based trauma system.

Our purpose was to perform a clinical and financial analysis of a pricing matrix system on operative hip fracture care concerning hemiarthroplasty for displaced femoral neck fractures in elderly low demand patients. Data analysis on 81 pre-matrix and 88 post-matrix patients demonstrated no significant differences in age, sex, ASA or fracture pattern between the two groups. No difference in surgical approach, cement use, prosthesis choice, operative time, estimated blood loss, or intra-operative complication rate was observed. No radiographic difference in subsidence or loosening was demonstrated. Readmission form cardiac, UTI, PE or DVT rates were similar between groups and no increase in revision surgery or mortality was observed. Overall, our hospital realized a 37% reduction in implant costs, resulting in $165,500 savings for the calendar year.
