3.8. At-Home Ketamine Therapy via Telehealth Platforms
- Efficacy: Both studies reported significant and rapid reductions in symptoms. Hull et al. (2022) [16], in a sample of 1247 patients, found that 62.8% achieved a response (≥50% reduction) on the PHQ-9 for depression, with a large effect size (d = 1.61). Similarly, 62.9% responded on the GAD-7 for anxiety (d = 1.56). Mathai et al. (2024) [15] replicated these findings in a much larger cohort of 11,441 patients, reporting a 56.4% response rate and a 28.1% remission rate for depression.
- Safety: The safety profile was generally favorable, with a low overall rate of adverse events (AEs) reported (4.7–4.8%). However, both studies noted the occurrence of serious adverse events (SAEs), which were exclusively psychiatric in nature. Mathai et al. [15] reported six SAEs, including psychosis and suicidal behavior, and 46 patients (0.4%) discontinued treatment due to AEs.
- Feasibility/Acceptability: The large-scale implementation and high treatment completion rates reported in both studies suggest that this model is a feasible and acceptable method for increasing access to care.
3.9. At-Home (Es)ketamine with Mobile or Telemedicine Support
- Efficacy: Kim et al. (2024) [17] found that esketamine nasal spray produced a significant reduction in depressive symptoms (mean PHQ-9 score decreased from 19.69 to 14.14; p < 0.001) in 29 patients with TRD. Notably, their mobile app detected a statistically significant improvement in depressive symptoms just one day after the first dose (p = 0.049). The case report by Longpré-Poirier et al. (2020) [20] did not measure efficacy quantitatively but noted a “positive experience” for a 61-year-old patient receiving remotely supervised intranasal ketamine.
- Safety: The safety findings were mixed. The case report by Longpré-Poirier et al. (2020) [20] reported no AEs. In contrast, Kim et al. (2024) [17] reported one death by suicide and one instance of self-harm, though both were attributed to the exacerbation of pre-existing symptoms rather than the drug itself. The case report by Johnson et al. (2024) [19] detailed the most severe safety event in this review: a life-threatening, unintentional overdose of 1200 mg of sublingual ketamine at home, which resulted in hospitalization.
- Feasibility/Acceptability: These studies suggest the model is feasible. Kim et al. (2024) [17] reported high patient adherence (89.6% in the first 3 days) to the daily monitoring app. Longpré-Poirier et al. (2020) [20] concluded that remote supervision was a feasible strategy to continue care during the COVID-19 pandemic. However, the overdose reported by Johnson et al. (2024) [19] raises critical concerns about the feasibility of ensuring patient safety without robust regulation and clear provider instructions.
3.10. Online Ayahuasca Rituals
- Efficacy: Efficacy was not measured clinically. The study found that the online format fulfilled an important social function by allowing the community to maintain its practice and foster a sense of global connection during a time of social isolation.
- Safety: The primary concerns were contextual rather than medical, including a higher potential for distractions, social anxiety from being on camera, and an “in-built tension between the social and spiritual dimensions of ritual.”
- Feasibility/Acceptability: The online format was a feasible ad-hoc alternative during the pandemic. However, acceptability was mixed. While it provided a crucial social lifeline, participants also reported an “impoverished ritual experience” and expressed concerns about the commodification of the sacred ritual.
