"In 2011, the total capacity of the treatment units (main treatment phase) was 7,853 slots (data for 75 of the 78 treatment units) (Figure 5.2). Most of the treatment slots were offered in OST units (6,789, 86.5%, Figure 5.10), and 13.5% (1,064, Figure 5.5) were offered by drug-free treatment programmes. Compared to 2010, in 2011 the treatment capacity increased by 18.8%, sustaining the increasing trend observed in the entire 2002-2011 period (Figure 5.2), which is a direct consequence of the increasing number of treatment units over the years (Figure 5.1).
"In 2011, the total number of people in treatment (main phase) was 9,047 (Figure 5.2), of whom 6,783 (75.0%) were offered services in OST, and 2,264 (25.0%) in drug-free settings. In addition, 4,934 (54.5%) were in continuous treatment (mainly OST), while 4,113 (45.5%) were admitted to the main phase of the treatment in the reporting year (Figure 5.2).
"In the period 2002-2011, the annual total number of individuals receiving treatment has been consistently increasing (Figure 5.2). In 2011, there has been a 9.1% increase in the number of people who received main treatment compared to 2010, with new admissions being the only group driving this increase (31.0% increase between the two years)."
