When people wait longer for treatment, sick leave gets longer and Kela's sickness allowance spending grows.
Of every 100 euros that a change to “Health” saves or brings in, 5 € comes back as extra spending on the line “Social protection: sickness and disability”, starting after 1 yr and building up to its full size over 2 yrs. (The other way round if the change adds spending or cuts taxes.)
Estimate; to be refined from Kela's sickness allowance statistics.
How the effect builds up over time
Share of the change's own effect on the balance, year by year while the change continues: −15% means 15% of a saving comes back as cost (or 15% of extra revenue is lost). With the default values.
You can switch the effect on or off and adjust its assumptions in the simulator under Cause-and-effect chains.
