Objective
While gel-formulated Rectal Microbicides (RM) are the first to enter clinical trials, rectal douching in preparation for anal intercourse is a common practise, thus RMs formulated as douches may be a convenient alternative to gels. Nonetheless, little is known about potential users’ thoughts regarding douche-formulated RMs or rectal douching practises, data needed to inform the advancement of douche-based RMs. This qualitative study examined thoughts regarding douches, their use as a RM and current douching practises among men who have sex with men and transgender women.
Methods
Ten focus groups and 36 in-depth interviews were conducted (N=140) to examine the overall acceptability of RM, of which one component focused on rectal douching. Focus groups and interviews were recorded, transcribed verbatim and coded; text relating to rectal douching was extracted and analysed. Sociodemographic information was collected using a self-administered questionnaire.
Results
Support for a douche-formulated RM centred on the possibility of combined pre-coital hygiene and HIV protection, and it was believed that a deeply-penetrating liquid douche would confer greater HIV protection than a gel. Drawbacks included rectal dryness; impracticality and portability issues; and, potential side effects. Non-commercial douching apparatus use was common and liquids used included detergents, vinegar, bleach, lemon juice and alcohol.
Conclusions
A douche-formulated RM while desirable and perceived as more effective than a gel-formulated RM also generated questions regarding practicality and side-effects. Of immediate concern were the non-commercial liquids already being used which likely damage rectal epithelia, potentially increasing HIV infection risk. Pre-coital rectal douching is common and a RM formulated as such is desirable, but education on rectal douching practices is needed now.
