Routine exposure to blood within hostel environments might help to explain elevated levels of hepatitis C amongst homeless drug users: insights from a qualitative study.

BACKGROUND: Although homelessness is a risk factor for HCV infection, there is a lack of research exploring the relationship between living in a hostel for homeless people and blood-borne viruses. The tendency to focus on risky injecting practices and HCV has also eclipsed the transmission risks potentially posed by spilt and dried blood.
METHODS: Semi-structured qualitative interviews were conducted with 40 homeless drug users (HDUs) (29 men and 11 women). The aim of the study was to explore the support needs of HDUs staying in emergency hostels or night shelters, but blood emerged as an unexpected recurring topic within participants' accounts. Accordingly, all blood data were coded and analysed inductively.
RESULTS: Participants reported that spilt and dried blood were routine features of hostel life, particularly in larger night shelters. Given that the hepatitis C virus can survive outside the human body for several weeks and even months, this poses a worrying but largely overlooked transmission risk. According to the HDUs interviewed, hostel providers were often slow to remove blood and other bodily waste, leaving residents to clean it themselves or to avoid soiled areas.
CONCLUSIONS: The routine presence of blood within hostel environments might help to explain elevated levels of HCV amongst homeless drug users. However, there is a need for robust quantitative and qualitative research to systematically test and explore associations between HCV and hostel life. Recommendations are made for improving hostel cleanliness, apprising hostel staff and residents of HCV and other blood-borne virus transmission risks, and ensuring that blood and other bodily waste are deemed unacceptable features of any hostel setting.
