How accessible are needle exchange programs in Manhattan to injecting drug user populations? A closer look at geographic access to needle exchange programs using a Geographic Information System (GIS)

A recent study of the New York City needle exchange program suggests that needle exchanges need to work on an operational level more closely with the rest of the healthcare network in order to build capacity and operational effectiveness¹². There are currently nine legal needle exchange programs that operate in New York City, with two different formats (storefront operations and street-based operations). Storefront operations provide a safe space for users, longer hours, and a space for on-site medical care, support groups and other services. Street-based operations offer syringes and support in a variety of ways—door to door, in vans or on street corners. Street-based exchanges reach out to people that do not usually come to the storefront operations.² While some of the programs have ties to other healthcare service providers, for the most part, needle exchange programs operate independently with little outside collaboration. This is mostly due to the following: (a) lack of resources to work on organizational development and strategic planning, (b) IDU/AIDS related stigma from the collaborating service-providers and (c) no coordinating body to provide vision and connection services.^2,13 The inconsistent support spurred by an ongoing debate about needle exchange effectiveness in reducing HIV transmission hinders operational effectiveness of individual needle exchange programs.

The opponents of needle exchanges argue that needle exchange programs facilitate and increase public health risks and crime rates in their surrounding areas. While this argument has been used to fuel public debate, studies have shown that needle exchange programs do not increase crime or public health risks within their proximity.^14,15 Russell Rockwell likened opposition to needle exchange programs to the NIMBY (Not In My Back Yard) approach of dealing with unfavorable social welfare and public health initiatives. ¹⁶NIMBYism refers to the organization of citizens at a grass roots level around an unfavorable activity occurring close to their home or place of work. Since needle exchange programs are viewed by many as unfavorable, their location is a hotly debated topic.

Does the location of a needle exchange program influence its effectiveness in HIV prevention? Studies in Glasgow, Scotland and New York City have tackled the location question. Both studies found that strategic geographic placement of needle exchange locations proved essential to the effectiveness of the needle exchange program and subsequent HIV prevention efforts.^16,17 These resource-constrained organizations need tools to identify where their services should be placed in order to attain optimal levels of service provision for affected populations.

The questions on the public health level, the geographic level, the political level and the operational level all intersect in this project. Through spatial analysis, a computerized geographic information system can synthesize geographic, political, public health and operational layers. The researchers of this project aimed to (1) map the existing needle exchanges in Manhattan; (2) map the high risk populations (IDUs living with AIDS); (3) map potential political constraints towards placement; (4) identify any holes in service provision; and (5) identify potential needle exchange locations.
