Introduction:
Despite the huge burden related to mental disorders, there is a huge treatment gap, especially in low- and middle-income countries. The WHO Model Lists of Essential Medicines (EML), updated every two years, aims to support countries in selecting a list of medicines that are considered essential for a basic health-care systems. However, the mental health section has seen limited revisions in the past 45 years. Aiming to address this gap, a proposal for a comprehensive revision of the entire mental health section was submitted to the WHO Expert Committee in 2022
Methods:
We submitted nine evidence-based applications to the WHO Expert Committee on the Selection and Use of Essential Medicines in December 2022, advocating for a substantial revision of the WHO EML mental health section. We conducted systematic reviews of the literature, meta-analyses and network meta-analyses on safety and effectiveness, GRADE assessment of the certainty of evidence, and cost-effectiveness evaluations.
Results:
All nine applications on psychotropic medicines for mental disorders were accepted by the WHO and contributed to the update of the EML. For psychotic disorders, first and second-generation antipsychotics were added. Substantial changes were made for mood and anxiety disorders as well, with the addition of second-generation antipsychotics for bipolar disorder and the removal of old tricyclics for depression and the addition of SSRIs to the option for obsessive-compulsive disorders. The list of benzodiazepines was also reduced to diazepam and lorazepam.
Discussion-Conclusion:
The comprehensive revision of the WHO EML mental health section will enhance access to the most effective, safe, and cost-effective medicines for mental disorders worldwide. Implementation of the proposed changes signifies a pivotal step toward ensuring that individuals worldwide have access to optimal treatments for mental health conditions, fostering a more inclusive and equitable approach to mental health care on a global scale.
