Issues around the Prescription of Half Tablets in Northern Switzerland: The Irrational Case of Quetiapine

Figure 2

Geographical distribution of split tablets in general (heat map; the warmer the colour (i.e., red), the higher the frequency, independently of the surface) and of half quetiapine tablets (purple bars; the higher the column, the higher the proportion) for each of the 51 retirement homes (,956). Grey areas indicate cantonal borders. The two distant homes located in cantons SG and GR (<0.1% split tablets; no quetiapine) are not depicted.
