Background:
The regain of pre-fracture basic mobility status at acute hospital discharge
is considered an important first step for patients recovering from a hip fracture (HF). The
Cumulated Ambulation Score (CAS) is a validated measure of basis mobility used in all
patients with hip fracture in Denmark and registered in the nationwide Danish Multidis-
ciplinary Hip Fracture Database (DMHFD).
Purpose / Aim of Study:
The aim of the study was to examine the association between
the regain of pre-fracture basic mobility at the time of acute hospital discharge, and
mortality and readmission within 30 days post-discharge in patients with HF.
Materials and Methods:
Using the DMHFD we identified 5,554 patients, aged ≥ 65
years admitted with an acute HF from Dec.1, 2015 to Nov. 30, 2016, at all the 25 Dan-
ish HF operating hospitals, and with both a pre-fracture and discharge CAS score. Regain
of basis mobility was defined as achieving the same or above the total pre-fracture CAS
score at discharge.
Findings / Results:
Only 37.9% (n=2,107) patients regained their pre-fracture ba-
sic mobility level, and with a 30-day mortality of 2.3% (n=48) compared with 7.2%
(n=246) of patients who did not regain their pre-fracture basic mobility level (p<0.001).
Correspondingly, 14.5% (n=300) and 17.8% (n=599) of patients were readmitted
within 30 days of discharge (p<0.001). Crude and adjusted odds ratio for death and
readmission will be presented during the DOS Congress.
Conclusions:
In this large national HF registry study of 5,554 Danish patients we found
that the regain of pre-fracture basic mobility level before acute hospital discharge was
strongly related to both 30-day mortality and readmission. This indicates the importance
of basic mobility independence as a primary early rehabilitation goal, and that the CAS
could be considered as an outcome parameter in other HF registries.
