The Brief

The brief was to investigate the possibility to reduce the transmission of Hepatitis C through the reuse of injection material among people who inject drugs.

The Result

The Solution - CollectOne

​

The final solutions is a combination of a service and a product with the collective name of CollectOne. The service, Collect, is the possibility to get perscripted injection material to pick up at any pharmacy in Gothenburg. Through this solution, the availability of new and sterile injection materials will increase drastically. 
 

The product, One, is a syrenge designed to only be funcioning for one use. The syrenge would be available at the pharmacys as well as at the syrenge exchange clinic. The syrenge has a small cylinder attached to the plunger that is pushed down to the bottom and get stucks when the liquid is injected.

 

Since the users will be creative in trying to reuse the syrenge, it is designed to not harm the user even if it is reused or misused.

Project overview

The process

​

The project was divided in to three main phases:

  • Gathering of data, which carried on throughout the project

  •  Ideation

  • Evaluation 

​​

The stakeholders to adress were mainly focused on the people who inject drugs but also the caregivers related to them and the Sahlgrenska University Hospital.

​

Methods

​

  • Expert interviews

    • KRIS (Kriminellas Revansch i Samhället)​

    • Substance Abuse Therapeuts

    • Hepatitis C & Transmission disease Experts

  • Attending a Hepatitis C conference

  • Literature reviews

  • Surveys

  • Visit/Observation at syrenge exchanges, clinics for homeless & Narcotics Anonymlous (NA)

​

Key findings​

​

Hepatitis C is mainly transmitted through sharing of injection materials among people who inject drugs. This is due to the lack of new injection materials to use for drug injection purposes. Therefore, old material is reused or shared or illegal material is bought which could be infected. In Gothenburg there is one clinic open one weekdays from 9-16 where users can get free injection materials. However, for a group of users that has problems with order and time the opening hours is an issue. Internationally these clinics have been a success to reduce the transmission of Hepatitus C and HIV but legislations in Sweden makes it difficult to copy the method (open more clinics).

 

The users have problems with time and order, their financial and general living situation and ignorance towards Hepatitis C.

 

Further issues are Sweden's attitude towards drugs and drug users and the restrictive drug politics in Sweden.

Reflections & Improvements

In this project we evaluated our process and design proposals with users, however the amount and diversity of users were not as good as it could have been. As well, I would have used users as a bigger part of a co-creational process. Furthermore, I would have done further benchmarking early on in the project since we found really useful inspiration in projects done internationally. Lastly, I would have chosen to work in faster, more agile phases and prototype the design proposals earlier through for example 3D-printing.
