No rest for the wounded: early ambulation after hip surgery accelerates recovery

BACKGROUND: Level 3 evidence-based guidelines recommend first walk after hip fracture surgery within 48 h. Early mobilization is resource and effort intensive and needs rigorous investigation to justify implementation. This study uses a prospective randomized method to investigate the effect of early ambulation (EA) after hip fracture surgery on patient and hospital outcomes. METHODS: Sixty patients (41 women and 19 men; mean age 79.4 years) admitted between March 2004 through December 2004 to The Alfred Hospital, Melbourne, for surgical management of a hip fracture were studied. Randomization was either EA (first walk postoperative day 1 or 2) or delayed ambulation (DA) (first walk postoperative day 3 or 4). Functional levels on day 7 post-surgery, acute hospital length of stay and destination at discharge were compared. RESULTS: At 1 week post-surgery, patients in the EA group walked further than those in the DA group (P = 0.03) and required less assistance to transfer (P = 0.009) and negotiate a step (P = 0.23). Patients in the EA group were more likely to be discharged directly home from the acute care than those in the DA group (26.3 compared with 2.4%) and less likely to need high-level care (36.8 compared with 56%). A failed early ambulation subgroup had significantly more postoperative cardiovascular instability and worse results for all outcome measures. CONCLUSION: EA after hip fracture surgery accelerates functional recovery and is associated with more discharges directly home and less to high-level care.
