Addressing risk in real-world clinical settings

In a real-world crisis care evaluation, Flow FL-100 use was associated with up to a 75% reduction in reported suicidal ideation and avoided psychiatric hospital admissions, suggesting potential value as a supportive intervention for patients with acute depressive symptoms.

Footnote

*Remission is defined as a score of <10 on MADRS. MADRS remission rate was a secondary endpoint of the study. The primary endpoint of the study reviewed between-group mean difference in HDRS-17 scores and was –2.3 points in favour of the active group (p=0.012).


†Comparison of monotherapy and adjunctive use of Flow FL-100 was a sub-analysis evaluation included as table 10 and 11 in the Empower Study. 


‡Findings from this crisis care evaluation are based on outcomes assessed after 3 and 6 weeks of treatment. The FDA-pivotal clinical trial evaluated its primary endpoint at 10 weeks; this difference in timeframe reflects the design and operational context of the crisis care service evaluation.
