Treatment of Hip and Knee Periprosthetic Joint Infection Requires Extensive Administrative Work

Treatment of periprosthetic joint infections (PJIs) typically requires more resource utilization than primary total joint arthroplasty. This study quantifies the amount of time spent in the electronic medical record (EMR) for patients who have PJI requiring surgical intervention.

A retrospective analysis of EMR activity for 165 hip and knee PJIs was performed to capture work during the preoperative and postoperative time periods. Independent sample t tests were conducted to compare total time based on procedure, age, insurance, health literacy, sex, race, and ethnicity.

The EMR work performed by the orthopaedic team was 338.4 minutes (min) (SD 130.3), with 119.4 minutes (SD 62.8) occurring preoperatively and 219.0 minutes (SD 112.9) postoperatively. Preoperatively, the surgeon's work accounted for 35.7 minutes (SD 25.4), mid-level providers 21.3 minutes (SD 15.9), nurses 38.6 minutes (SD 36.8), and office staff 32.7 minutes (SD 29.9). Infectious disease colleagues independently performed 158.9 minutes (SD 108.5) of postoperative work. Overall, PJI of the knees required more postoperative work. Secondary analysis revealed that patients who have hip PJI and a body mass index <30 and patients <65 years of age required more work when compared to the PJI of heavier and older individuals. There was no difference in total work based on insurance, health literacy, race, or ethnicity.

Over 8 hours of administrative work is required for surgical management of PJI. Surgeons alone performed 451% more work for PJI during the preoperative period (7.9 versus 35.7 min) compared to primary total joint arthroplasty. In efforts to provide best care for our sickest patients, much work is required perioperatively. This work is necessary to consider when assigning value and physician reimbursement.
