"42 OST units currently operate in Greece of which nine (9) methadone substitution units and thirty-three (33) buprenorphine substitution units. Only OKANA provides substitution treatment services.
"Capacity and treated population
"As shown in Figure 5.10, the total capacity of OST units in 2011 was 6 789 (data for 38 of the 39 OST units). A total of 6,783 individuals9 were offered OST services, 32.7% (n=2 218) of whom were in methadone –and 67.3% (n=4 565) in buprenorphine OST units (Figure 5.10).
"In 2011 the total capacity of the OST programme increased by 28.1% over 2010, was 41.3% higher compared to 2008 and quintupled compared to 2002, while there is no difference in capacity between 2008 and 2009 (Figure 5.11). As it is shown in Figure 5.11 the increase in the capacity of OST from 2008 to 2011 is mostly attributed to the increase in the capacity of the buprenorphine (increased by 100%), while the capacity in methadone decreased by 13%.
"The total number of people in treatment is continuously increasing between 2002 and 2011. More specifically, in 2011 the total number of clients in OST increased by 8.3% over 2010 and 34.4% compared to 2008, whereas it was quadrupled compared to 2002 (Figure 5.12). In 2011 admissions increased by 43.7% compared to 2010, mostly because of the opening of the OST units (Figure 5.1).
"The increase between 2008 and 2011 is due to the increased number of clients by 106% in buprenorphine, while the number of clients in methadone decreased by 22% (Figure 5.13)."
