Abstract Background Programmatic data from New York City syringe exchange programs suggest that many clients visit the programs infrequently and take few syringes per transaction while separate survey data from individuals using these programs indicate that frequent injecting - at least daily -is common. Together these data suggest a possible syringe gap between the number of injections performed by users and the number of syringes they are receiving from programs for those injections. Methods We surveyed a convenience sample of 478 injecting drug users in New York City at syringe exchange programs to determine whether program syringe coverage was adequate to support safer injecting practices in this group. Results Respondents reported injecting a median of 60 times per month visiting the syringe exchange program a median of 4 times per month and obtaining a median of l0 syringes per transaction more than one in four reported reusing syringes. .
