The funds available for the health services at present are not sufficient. When assessing their desirable volume, we must consider a number of factors which influence the needs of financial means. This comprises direct and indirect action, in different spheres and direction and of different intensity. Different factors are not quantifiable to the same extent; some can be expressed only verbally. The resultant of their action which may have the same trend (then the effects add) or have an opposite trend (then the effects cancel out), is then the concrete pressure which in a concrete situation affects the concrete need of financial means. A team of specialists will have to study the identification of factors and assess the assumed forces of their action.
