Influence of social deprivation on intensive care outcome

Objective: To assess the influence of social deprivation on outcome from ad mission to the intensive care unit. Design: Retrospective cohort study. Set ting: Tertiary referral centre mixed adult intensive care unit (ICU). Patie nts: Seven hundred seventy-four consecutive admissions to the ICU over a 2- year period. Interventions: None. Measurements and results: Age, admission illness severity measured by APACHE II score, predicted hospital mortality, actual hospital mortality and length of ICU stay were obtained for all pat ients. Social deprivation was assessed by Carstairs Score for postcode sect or of residence categorised from 1 (most affluent) to 7 (most deprived). Ca rstairs Scores were obtained for 716 patients. When patients in categories 6 and 7 were compared with the others there were no significant differences in age, admission illness severity, predicted or actual hospital mortality and length of ICU stay. On multivariate analysis there was no evidence of an increased mortality risk for patients in categories 6 and 7 (p = 0.256, odds ratio 1.2, 95 % confidence interval 0.9-1.7). Conclusions: Social depr ivation does not influence outcome in patients admitted to the ICU.
