dc.description.abstractObjective To quantify hospital use in a general population over ten years follow up and to examine related factors in a general population based cohort. Design A prospective population based study of men and women. Setting Norfolk, United Kingdom Participants 11228 men and 13786 women aged 40-79 years in 1993-1997 followed between 1999-2009. Main outcomes measures Number of hospital admissions and total bed days for individuals over a ten year follow-up period identified using record linkage; five categories for admissions (from zero to highest>=7) and hospital bed days (from zero to highest>=20 nights). Results Over a period of ten years, 18179 (72.7%) study participants had at least one admission to hospital, 13.8% with 7 or more admissions and 19.9% with 20 or more nights in hospital. In logistic regression models with outcome >=7 admissions, low education level OR 1.14 (1.05-1.24), age OR per 10 year increase 1.75 (1.67-1.82), male sex OR 1.32 (1.22-1.42), manual social class 1.22 (1.13-1.32), current cigarette smoker OR 1.53 (1.37-1.71), and body mass index > 30 kg/m² OR 1.41 (1.28-1.56) all independently predicted the outcome with p<0.0001. Results were similar for those with >=20 hospital bed days. A risk score constructed using male sex, manual social class, no educational qualifications; current smoker, and body mass index > 30 kg/m², estimated percentages of the cohort in the categories of admission numbers and hospital bed days in stratified age bands with two to three fold differences in future hospital use between those with high and low risk scores. Conclusions The future probability of cumulative hospital admissions and bed days appears independently related to a range of simple demographic and behavioural indicators. The strongest of these is increasing age with high body mass index and smoking having similar magnitudes for predicting risk of future hospital usage.
