Development of a respiratory severity score for hospitalized adults in a high HIV-prevalence setting—South Africa, 2010–2011

Table 3 Risk factors for inpatient mortality from the final multivariable model for adults hospitalized with LRTI with ACHU (age, confusion, HIV, urea) respiratory severity score, South Africa, 2010–2011

Risk factor	Adjusted Odds Ratio (95% Confidence Interval)	p-value	Beta (unexponentiated regression coefficient)	Score^a
Age ≥ 45	2.3 (1.4–3.9)	0.001	0.85	1
Confusion	9.3 (3.8–22.4)	<0.001	2.23	2
HIV-infected	4.2 (1.8–10.1)	0.001	1.44	1
Urea > 7 mmol/L	4.6 (2.7–7.8)	<0.001	1.53	2

^aThe point value assigned for the score was determined by rounding the beta coefficient to the nearest integer
