KCE Reports 90 Making General Practice Attractive: Encouraging GP attraction and Retention 11
Tables 5 and 6 in appendix 1.9 give details on the percentages of inactivity or small
practices for licensed/unlicensed general practitioners by gender and by age group
(1995, 2000 and 2005).
1.4.1.4 Inactivity in the curative sector for the licensed GPs: analysis per linguistic
community (INAMI/RIZIV database)
Figures 3 and 4 in appendix 1.9 show the inactivity percentages for the French-speaking
and the Dutch-speaking licensed GPs. For further details on those two figures, see table
7 in appendix 1.9.
Although the number of licensed GPs increased in the French-speaking part (from 5849
in 1995 to 6644 in 2005), the proportions of inactivity increased too for all age groups
(from 4% in 1995 to 11% in 2005) (figure 3, appendix 1.9).
The inactivity proportion for the younger age group increased from 5.6% in 1995 to 8%
in 2005.
The number of licensed GPs was higher in the Dutch speaking part (from 6443 in 1995
to 7526 in 2005) (table 7 in appendix 1.9) compared to the French-speaking part of
Belgium. However, the increase of inactivity proportion was slightly higher in the
Dutch-speaking part (from 4% in 1995 to 13% in 2005) (figure 4, appendix 1.9)
compared to the French-speaking part of Belgium (from 4% in 1995 to 11% in 2005)
(figure 3, appendix 1.9). However, the differences were not statistically significant (table
4 below).
The small practice percentages were higher in the French-speaking part than in the
Dutch-speaking part of Belgium and this for all age groups (table 7 appendix 1.9).
1.4.1.5 Inactivity in the curative sector for the licensed GPs: annual growth rates by age
group and gender (INAMI/RIZIV database)
Overall, the inactivity rate of licensed GPs increased annually, for all genders and in
mostly all age groups (table 3 below). As an example, inactivity increased by an annual
8.3% among men and 6% among women for those aged 30-39 years. The only exception
is the youngest age group (its size is however small): the inactivity rate decreased by
non-significant 2% annually for the men between 1995 and 2005, while it increased by a
4% for women.
We tested whether men and women had different annual growth rate of inactivity (see
p-value column). Broadly the test was non significant or had a borderline significance
(for 30-39 and 50-59). There is very slight evidence that the growth rate of inactivity
has been higher for men than women.
