Ensure confidentiality and session containment

The manuals converge on protecting privacy, limiting exposure, and keeping sessions contained. Across in-person and remote formats, they recommend confidentiality, secure handling of protected information, private rooms or private settings, and reducing access to distractions, identifiers, and outside contact. Several sources also emphasise emergency readiness alongside privacy, with access to communication technology for urgent support or emergency services. They also overlap on clear session boundaries. The manuals recommend restricting recording, limiting disclosure of other participants or protected material, and setting behavioural or logistical agreements that support containment, such as remaining in the treatment area, avoiding harmful behaviour, and clarifying contact and follow-up expectations. Group-based material adds a specific confidentiality layer, where sharing one’s own experience is acceptable but sharing others’ stories is not. The main differences are in format and emphasis. Some sources focus on remote telehealth safeguards, such as approved videoconference platforms, private rooms, screen-sharing precautions, and email or invitation hygiene, while others focus on in-person containment, such as closed cabinets, restricted items, no phone or television, and limiting contact with other patients. The MDMA manuals place more weight on formal behavioural agreements and overnight stay logistics, whereas the ketamine group material focuses more on peer confidentiality and the limits of confidentiality in a group setting.
