Predicting inpatient rehabilitation length after hip or knee replacement
Transforming Rehabilitation: Personalised Care for a Better Quality of Life (PREPARE, Phase 2)
This project will try to use past hospital records to train and test a model that predicts how long adults who had hip or knee replacement for osteoarthritis will need inpatient rehabilitation.

What this trial studies
Researchers will extract retrospective clinical and surgical data from patients who underwent total hip or knee replacement at IRCCS Galeazzi and were discharged to inpatient rehabilitation in 2018. They will analyze demographic, surgical, laboratory, pain, cognitive, and functional measures (including Barthel Index and physiotherapy evaluations) to train and externally validate a predictive model for inpatient rehabilitation length of stay. The primary outcome is rehabilitation length of stay and secondary outcomes include place of discharge, burden of care at discharge, and functional recovery. No new patients will be recruited because the analysis uses existing clinical records stored in the hospital databases.
Who should consider this trial
Good fit: Adults (≥18 years) who had total hip or knee replacement for osteoarthritis at IRCCS Galeazzi in 2018 and were subsequently discharged to inpatient rehabilitation are the focus of this analysis.
Not a fit: Patients under 18, those who had other types of surgery, those treated at other hospitals, or those with incomplete clinical records are not represented and are unlikely to benefit directly from this dataset or model.
Why it matters
Potential benefit: If successful, the model could help clinicians anticipate rehabilitation needs and improve discharge planning to shorten stays and tailor post-operative support.
How similar studies have performed: Similar predictive-model approaches for length of stay after joint replacement have shown promise in prior studies, though robust external validation across centers is still limited.
