Integrating Psychiatric, Psychotherapeutic, and Nursing Care in Intranasal Esketamine for Treatment-Resistant Depression

We conducted a narrative review informed by a structured literature search in major databases from inception to the most recent update. Search terms combined ‘esketamine’/‘Spravato’ with ‘treatment-resistant depression’, ‘nursing’, ‘psychotherapy’, ‘multidisciplinary’, and ‘implementation’. Outcomes prioritized in the synthesis included depressive symptom severity/response, relapse prevention, safety/tolerability, anhedonia, suicidality monitoring, functional outcomes, and patient-reported experience/retention. Based on this evidence, an integrated, phase-based multidisciplinary framework for esketamine treatment was developed.

Available evidence supports the efficacy of intranasal esketamine in reducing depressive symptoms in TRD, with growing real-world data confirming its effectiveness and safety. Beyond global symptom improvement, studies highlight benefits on clinically relevant domains such as anhedonia and suicidality trajectories, as well as meaningful patient-reported outcomes. However, the complexity of esketamine delivery requires structured clinical pathways. The proposed model delineates complementary roles for medical supervision, nursing care, and psychotherapy across pre-treatment assessment, induction and session delivery, post-session integration, and maintenance phases, emphasizing safety, continuity of care, and patient-centred monitoring.
