This paper uses the Cost of Illness (COI) framework to estimate the co
st of rheumatoid arthritis (RA) to society in the year 1992/93. By doi
ng so, a clear insight is given into the many cost elements of RA trea
tment and monitoring. This paper estimates point prevalence rates of 2
.06 and 6.94/1000 persons at risk for men and women, respectively, sho
wing that prevalence is three times higher amongst women than men. Fur
ther to this, prevalence increases with age in both sexes, resulting i
n very high prevalence rates for RA amongst the elderly. The total eco
nomic impact of RA in England was estimated to be pound 1.256 billion
in 1992, of which 52% was a result of production loss caused by RA dis
ability.
