Abstract

Objectives
The majority of female street-based sex workers (SSWs) are dependent on illicit drugs and sell sex to fund their drug use. They typically face multiple traumatic experiences, starting at a young age, which continue through sex work involvement. Their trauma-related symptoms tend to increase when drug use is reduced, hindering sustained reduction. Providing specialist trauma care to address post-traumatic stress disorder (PTSD) alongside drug treatment may therefore improve treatment outcomes. Aims to (i) evaluate recruitment and retention of participants; (ii) examine intervention experiences and acceptability; and (iii) explore intervention costs using mixed methods feasibility study.

Setting
Female SSW charity premises in a large UK inner city.

Participants
Females aged 18 years or older, who have sold sex on the street and used heroin and/or crack cocaine at least once a week in the last calendar month.

Intervention
Female SSW-only drug treatment groups in a female SSW-only setting delivered by female staff. Targeted post-traumatic stress disorder (PTSD) screening then treatment of positive diagnoses with eye movement desensitization and reprocessing (EMDR) therapy by female staff from a specialist NHS trauma service.

Results
(i) Of 125 contacts 11 met inclusion criteria and provided informed consent, 4 reached the intervention final stage (ii) Service providers said working in collaboration with other services was valuable, the intervention was worthwhile and had a positive influence on participants. Participants viewed recruitment as acceptable and experienced the intervention positively. The unsettled nature of participant’s lives was a key attendance barrier. (iii) The total cost of the intervention was £11,710, with staff costs dominating.

Conclusions
Recruitment and retention rates reflected study inclusion criteria targeting women with the most complex needs. Two participants received EMDR demonstrating that the three agencies working together was feasible. Staff heavy costs highlight the importance of supporting participant attendance to minimise per participant costs in a future trial.
