Abstract

Background: The use of specialized orthopedic surgery (SOS) units in total knee arthroplasty (TKA) patients is well established. The number and costs of arthoplasty surgeries continue to increase, requiring institutions to reexamine their existing practices for financial sustainability. Objective: The objective of this study was to determine whether having elective TKA patients in SOS units affects resource utilization and outcomes. Design: The study was designed to retrospectively compare elecTIve TKA patients from 1996 to 2004 admitted directly to SOS units with those admitted to nonorthopedic nursing (NON) units. Setting: The setting was an academic teaching hospital. Patients: Five thousand five hundred and thirty-four patients met inclusion criteria. Of these, 5082 (patients 91.8%) were admitted to SOS units and 452 (8.2%) to NON units. Measurements: The primary outcomes measured were length of stay (LOS) and costs, adjusted for age, sex, surgical year, comorbidities, and American Society of Anesthesiologists status. Secondary outcomes were 30-day mortality, readmissions, reoperations, and discharge disposition. Results: Mean age of the patients in SOS and NON units was 68.3 and 67.9 years, respectively (P = .50). Adjusted LOS was 0.234 days shorter in SOS units (95% CI: 0.083, 0.385). Adjusted total and hospital cost savings in the SOS unit group were $600 (95% CI: $122, $1079) and $594 (95% CI: $141, $1047), respectively. More NON-unit patients required unanticipated transfers to the intensive care unit (ICU) from the general postoperative nursing unit (3.1% vs. 1.63%; P = .023); however, the mean number of ICU days did not differ between groups. NON-unit patients were more likely to be discharged with home health care (P < .001). There were no differences in 30-day outcomes. Conclusions: Patients on SOS units following elective TKA have a reduced LOS anal decreased total and hospital costs. Our results should encourage hospitals to reevaluate postoperative patient flow to optimize resource utilization.
