Abstract

Introduction: The World Health Organization (WHO) has been instrumental in developing evidence-based guidelines to address mental, neurological, and substance use disorders through its Mental Health Gap Action Programme (mhGAP). These guidelines provide essential recommendations for healthcare professionals to deliver effective care in non-specialized health settings. Aim: This article aims to review and analyze the updated WHO guidelines on the mhGAP intervention for mental, neurological, and substance use disorders, focusing on their significance, content, and implications for clinical practice. Methods: A comprehensive review of the WHO documents published in 2023, including the "mhGAP intervention guide for mental, neurological, and substance use disorders in non-specialized health settings" and the "Update of the Mental Health Gap Action Programme (mhGAP) guidelines for mental, neurological, and substance use disorders, 2015," was conducted. The review examines the scope of the guidelines, their recommendations, and the evidence supporting them. Results: The updated WHO guidelines cover a wide range of mental health conditions, including alcohol use disorders, anxiety disorders, depression, and more. Each guideline provides evidence-based recommendations for prevention, diagnosis, and treatment, with the aim of improving access to quality mental health care in diverse healthcare settings. The guidelines are freely accessible online through the WHO's mhGAP Evidence Resource Centre website, offering detailed evidence profiles and recommendations for healthcare professionals. Conclusions: The WHO guidelines on the mhGAP represent a critical resource for healthcare professionals worldwide, offering evidence-based guidance for the delivery of mental health care. By providing standardized recommendations informed by the best available evidence, these guidelines support the implementation of evidence-based practice and contribute to improved patient outcomes. The WHO's commitment to updating and disseminating these guidelines underscores its dedication to promoting mental health equity and advancing evidence-based care globally.
