Annual costs of chronic obstructive pulmonary disease in Finland during 1996–2006 and a prediction model for 2007–2030

Abstract

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major burden for the health care system, but the exact costs are difficult to estimate and there are insufficient data available on past and future time trends of COPD-related costs. AIMS: The aim of the study was to calculate COPD-related costs in Finland during the years 1996-2006 and estimate future costs for the years 2007-2030. METHODS: COPD-related direct and indirect costs in the public health care sector of the whole of Finland during the years 1996-2006 were retrieved from national registers. In addition, we made a mathematical prediction model on COPD costs for the years 2007-2030 on the basis of population projection and changes in smoking habits. RESULTS: The total annual COPD-related costs amounted to about 100-110 million Euros in 1996-2006, with no obvious change, but there was a slight decrease in direct costs and an increase in indirect costs during these years. The estimation model predicted a 60% increase up to 166 million Euros in COPD-related annual costs by the year 2030. This is caused almost entirely by an increase in direct health care costs that reflect the predicted ageing of the Finnish population, as older age is a significant factor that increases the need for hospitalisation. CONCLUSIONS: The total annual COPD-related costs in Finland have been stable during the years 1996-2006, but if management strategies are not changed a significant increase in direct costs is expected by the year 2030 due to ageing of the population.

S eng hs and limi a ions o his s udy
This s udy is based on na ional egis e s co e ing he public heal h
ca e sys em in he whole o Finland and gi es a eliable es ima e
on he ue cos s o COPD. Howe e , ou es ima e o o al cos s is
likely a conse a i e one because o se e al easons. Fi s , he
exac eason and p ima y diagnosis o hospi alisa ion o a subjec
wi h COPD and many como bidi ies is no always s aigh o wa d,
and some exace ba ions o COPD a e ce ainly ea ed unde o he
diagnoses, which may lead o unde es ima ion o hospi alisa ion
cos s. Second, ou pa ien isi s in p i a e heal h ca e sys ems o in
p ima y public heal h ca e could no be included because o lack
o eliable egis e s. Howe e , his is p obably no a significan
issue, as he cos s o ou pa ien isi s a e small when compa ed
wi h hospi alisa ions and indi ec cos s, and he numbe o isi s
o elde ly people in p i a e heal h ca e is e y small. Thi d, no all
pa ien s wi h mild o mode a e COPD ha e a special eimbu se-
men o medica ion, and he medica ion cos s o subjec s wi hou
his eimbu semen a e no included in his analysis. As
medica ion cos s a e highe in subjec s wi h se e e COPD, his
may no be a ma ked flaw bu leads o unde es ima ion in any
case. Fu he mo e, he indi ec cos s a e always di ficul o define
and calcula e, and we did no include, e.g., he possibili y ha
mo ali y due o COPD migh dec ease he expenses o e i emen
pensions due o ea lie dea h o subjec s wi h COPD.
Ou es ima e o u u e cos s assumes ha he e ec i eness o

The e o e, he accu acy in p edic ing u u e smoking habi s is no

much mo e pi o al o longe ime pe iods.
A weakness o he cu en s udy, as wi h all p edic ion models,
is ha in p edic ing u u e COPD- ela ed cos s we needed o

e en conse a i e, as possible.
Implica ions o u u e esea ch, policy and p ac ice
In he pas , he p e alence o COPD has been on he ise due o
ageing o he popula ion, and he medicine cos s ha e also isen
as new d ugs ha e become a ailable. Howe e , hese ac o s
inc easing he cos s ha e been balanced ou by inc eased
e ficiency o he heal h ca e sys em ha has dec eased he leng h
o in-hospi al pe iods. The Finnish popula ion will be ageing
much mo e apidly du ing he nex 20 yea s han du ing he yea s
1996–2006. The numbe o pa ien s wi h COPD will inc ease
especially in he olde age g oups, in which also he need
o hospi al ea men is he g ea es . This is why he e will be
ageing- ela ed inc ease in o al COPD- ela ed cos s in he u u e,
al hough his did no ake place in he pas . As he olde age
g oups ha e al eady e i ed, he highe p e alence o COPD
among hese subjec s does no cause an inc ease in indi ec cos s
ha a e ela ed o loss o p oduc i i y.
The ageing- ela ed inc ease in COPD cos s should be aken in o
accoun in Finland when planning he na ional heal h ca e
s a egy. The esul s can be expanded o o he wes e n coun ies
wi h simila smoking habi s and ageing o he popula ion. As he
s eamlining o he heal h ca e sys em in ea ing exace ba ions
has al eady aken place, his is likely no a significan op ion in
educing he cos s anymo e. Ins ead, ocus should be on smoking
policy o dec ease age-adjus ed COPD incidence and on he
managemen o s able COPD o dec ease he isk o
exace ba ions.
Conclusions
In conclusion, he annual cos s o COPD in Finland ha e been
s able du ing he yea s 1996–2006, bu he cos s a e es ima ed o
