Abstract

Introduction: Postoperative day 1 (POD 1) mobilisation is a key clinical indicator for the fragility hip fracture surgery population. This study aimed to evaluate the current trends of POD 1 mobilisation at our institution and to review the relationships between early mobilisation and outcomes of early functional recovery, length of stay (LOS) and discharge destination.

Methods: In this preliminary observational study, data pertaining to demographics, premorbid function, health status, injury and surgical factors, POD 1 mobilisation status and clinical outcomes of interest were retrieved from eligible patients. Patients who attained POD 1 ambulation formed the early ambulation (EA) group, while the remaining patients formed the delayed ambulation (DA) group. Data were analysed for any significant difference between the groups.

Results: One hundred and fifteen patients were included in the analysis. The rate of patients achieving at least sitting out of bed on POD 1 was 80.0% (n=92), which was comparable to the data available from international hip fracture audit databases. There were 55 (47.8%) patients in the EA group and 60 (52.5%) patients in the DA group. The EA group was approximately nine times more likely to achieve independence in ambulation at discharge compared to the DA group (adjusted odds ratio 9.20, 95% confidence interval 1.50-56.45; P = 0.016). There were observed trends of shorter LOS and more proportion of home discharge in the EA group compared to the DA group (P > 0.05).

Conclusion: This is the first local study to offer benchmark of the POD 1 mobilisation status for this population. Patients who attained POD 1 ambulation had better early functional recovery.
