PURPOSE : To examine whether the length of stay (LOS) after hip fracture surgery
was related to mortality after discharge by comparing between hospitals in Japan
and the United States (US).
This is a retrospective observational study
of three hospitals in Japan and two in the Pacific Northwest in the US. The
median follow-up day was 276 days after surgery. The participants were 65 years
or older who had experienced hip fracture and were admitted to one of the study
hospitals for surgery. RESULTS: The median LOS after surgery was 34 days in Japan
and 5 days in the US. The survival rate was 89.5% in Japan and 77.2% in the US
among patients who could be followed-up. In the Cox regression, every 10 day
increase in the LOS after surgery was associated with a 26% reduction in the risk
of mortality (Hazard ratio = 0.744, p = 0.014) after adjusting for LOS before
surgery, patients' basic characteristics, number of complications and country.
CONCLUSIONS: Shorter lengths of stay after surgery did not predict better
survival across the two countries. Larger longitudinal or randomized studies that
determine the effects of LOS after surgery on mortality are necessary.
