Functional decline in geriatric rehabilitation ward; is it ascribable to hospital acquired infection? A prospective cohort study

Table 2 Factors independently associated with deteriorated activities of daily living (ADL) during the rehabilitation unit stay

	Model 1 Adjusted OR [95%CI]	P value	Model 2 Adjusted OR [95%CI]	P value
CIRS-G Index	1.38 [1.06–1.81]	0.02	_	_
CIRS-G score ≥ 2 for respiratory diseases	_	_	3.23 [1.21–8.59]	0.02
CIRS-G score ≥ 2 for psychiatric diseases	_	_	4.89 [1.27–18.72]	0.02
Albumin level < 35 g/l	2.65 [0.98–7.10]	0.05	2.98 [1.12–7.92]	0.03
MMSE_{1-point decrease}	1.09 [1.00–1.18]	0.03	_	_
CRP	0.99 [0.96–1.02]	0.55	0.99 [0.97–1.02]	0.56

Adjusted ORs were estimated by logistic regression adjusted for CIRS-G index, Albumin level and MMSE for model 1 and adjusted for CIRS-G score ≥ 2 for respiratory diseases, CIRS-G score ≥ 2 for psychiatric diseases and Albumin level for model 2. (P value: Wald test)
MMSE Mini-Mental State Examination; CIRS-G Cumulative Illness Rating Scale for Geriatrics, CIRS-G Index calculated as the number of categories with score ≥ 2. Model 1 considers factors associated with ADL deterioration and is adjusted by CIRS-G index, albumin level < 35 g/l, and MMSE. Model 2 considers factors associated with ADL deterioration and is adjusted for CIRS-G score ≥ 2 for respiratory and psychiatric diseases and albumin level < 35 g/l.
