Abstract
Purpose
The aim was to investigate the interplay between patient characteristics and (1) length of hospital stay and (2) one-year patient-reported outcome following total knee and hip arthroplasty.
Methods
Event (survival) analysis and structural equation modelling were performed for 1001 patients undergoing knee (n = 566) and hip (n = 435) arthroplasty in a single institution.
Results
Age, body mass index and co-morbidities were independent predictors of length of stay in both event analysis and structural equation modelling. These patient characteristics and type of arthroplasty had both small direct and indirect effects on patient-reported outcome measures at one year. Length of stay had a small effect (<2 %) in SF-36 scores at one year.
Conclusion
Predictors that influence length of stay also impact on one-year post-operative outcome and therefore should be taken into account during patient selection and discharge planning.
Level of evidence
Retrospective cohort study, Level III.
