Methods
Нe rehabilitation unit is located within the campus of a regional
hospital and is well equipped with all the modern facilities for both in
and out patient referrals. Нe majority of patients referred are stroke,
acquired brain injury, spinal cord injury and complex medical and
post-surgical deconditioning.
Нis is a retrospective cohort study involving the review of
electronic medical records of all patients discharged from a general
rehabilitation inpatient unit located within a general hospital in Asia.
Нe review period was from 1st July 2014 to 30th June 2015. Medical
records of patients discharged within the review period were screened
for serums 25-hydroxyvitamin D results which were obtained during
the same admission. Patients with end stage renal failure on dialysis or
stage V chronic kidney disease were then excluded.
Demographic data (age, gender, race), primary rehabilitation
diagnosis, length of stay, discharge destination, medical comorbidities,
body mass index, bone mineral densitometry, Functional
Independence Measure (FIM) on admission and discharge and serum
25-hydroxyvitamin D level for each patient were collected.
In this study, we have defined vitamin D deficienc based on the
Endocrine Society Clinical Practice Guideline, which is that of a serum
25-hydroxyvitamin D level less than 20 ng/ml.
Нe FIM is a functional assessment tool commonly used in the
inpatient rehabilitation setting. Eighteen diوٴerent activities (13 motor,
5 cognitive) are scored on a scale of 1 to 7, with a score of 1 indicating
complete dependence and 7 indicating complete independence. By
adding the scores for each subscale, a total score can range from 18
points (lowest possible level of functional independence) to 126 points
(highest possible level of functional independence). FIM eٹcienc is
calculated by dividing the diوٴerence in discharge and admission FIM
scores by inpatient rehabilitation length of stay [6].
Statistical analysis was performed using SPSS 19 statistical soіware,
