Objectives

A current trend in total hip replacement (THR) is the use of minimally invasive surgery. Little is known, however, about the impact of minimally invasive THR on resource use and length of stay. This study analyzed the effect of minimally invasive surgery on hospital costs and length of stay in German hospitals compared with conventional treatment in THR.

Methods

We used patient-level administrative hospital data from three German hospitals participating in the national cost data study. We conducted a propensity score matching to account for baseline differences between minimally invasively and conventionally treated patients. Subsequently, we estimated the treatment effect on costs and length of stay by conducting group comparisons, via paired t tests and Wilcoxon signed-rank tests, and regression analyses.

Results

The three hospitals provided data from 2886 THR patients. The propensity score matching led to 812 matched pairs. Length of stay was significantly higher for conventionally treated patients (11.49 days vs. 10.90 days; P 0.001) in contrast to significantly higher staff and overhead costs for conventionally treated patients.

Conclusions

Minimally invasive surgery was compared with conventional THR and was found to be associated with a reduced length of stay. Total hospital costs, however, did not differ between the two treatment groups, because of higher implant costs for minimally invasively treated patients.
