“Low dead space” syringes with permanently attached needles
retain less fluid, blood, and HIV after use than standard “high dead space”
syringes. This reduces the probability of HIV transmission if they are shared
by people who inject drugs (PWID). The World Health Organization recently
recommended that needle and syringe programs (NSP) offer clients low dead space
syringes. The success of this recommendation will depend on PWID switching to
low dead space needles and syringes. This paper examines the needles and
syringes that PWID in Tajikistan use and factors that influence their choices.
In May 2014, we conducted six focus groups in Kulob and six
in Khorog, Tajikistan, with a total of 100 participants. NSP staff members
recruited participants. Focus group topics included the needles and syringes
used and factors that influence choice of needles and syringes. Focus groups
were conducted in Russian and Tajik, audio recorded, transcribed, and
translated into English. The translated files were imported into NVivo 10 for
coding and analysis.
All participants in both cities were male and reported
injecting heroin. Everyone also reported using syringes with detachable needles
almost exclusively. The most popular syringe sizes were 2 and 5 ml.
Needles ranged in gauge from 25 to 21 g. Needle gauge was influenced by
the size of the vein, the viscosity of drug solution to be injected, and problems
with blood clotting. Needles ranged in length from 12 to 38 mm, with 25
and 32 mm being the most popular. Needle length was influenced by the
depth of the vein being used. Many PWID inject volumes of fluid greater than
1 ml into deep veins that require needles at least 25 mm long and
25 g in diameter.
Most low dead space syringes are 1-ml insulin syringes with
12 mm 28 g permanently attached needles. Findings from this project
suggest that these will not be acceptable to PWID who need larger syringes and
longer and thicker needles that are detachable. Low dead space detachable
needles appear to be an acceptable option that could overcome barriers to the
widespread use of low dead space equipment for reducing HIV and HCV
transmission.
