This paper reports the results of a 'cost-of-illness' study of the socio-ec
onomic costs of back pain in the UK. It estimates the direct health care co
st of back pain in 1998 to be pound 1632 million. Approximately 35% of this
cost relates to services provided in the private sector and thus is most l
ikely paid for directly by patients and their families. With respect to the
distribution of cost across different providers, 37% relates to care provi
ded by physiotherapists and allied specialists, 31% is incurred in the hosp
ital sector, 14% relates to primary care, 7% to medication, 6% to community
care and 5% to radiology and imaging used for investigation purposes. Howe
ver, the direct cost of back pain is insignificant compared to the cost of
informal care and the production losses related to it, which total pound 10
668 million. Overall, back pain is one of the most costly conditions for wh
ich an economic analysis has been carried out in the UK and this is in line
with findings in other countries. Further research is needed to establish
the cost-effectiveness of alternative back pain treatments, so as to minimi
se cost and maximise the health benefit from the resources used in this are
