Improving mental health care in humanitarian emergencies

Editorials 666 The mental health needs of people affected by emergencies are significant, but often overlooked by health-care providers. 1 The world is facing an unprecedented number of humanitarian emergencies arising from conflict and disasters. In 2014, nearly 60 million people were forcibly displaced due to conflict, the highest number on record. 2 Climatic and geological hazards continue to take their toll, as seen recently following the devastating earthquake in Nepal, cyclone in Vanuatu and flooding in China, Malawi and Myanmar. Although estimated rates of mental disorder after conflict vary due to differences in context and study methods, a meta-analysis of methodically stronger surveys indicate average rates of 15–20% for depression and post-traumatic stress disorder. 3 This is in line with projected rates of mental disorder after disasters. 4 In humanitarian emergencies, mental health complaints are diverse in nature and severity. First, grief and acute stress are usually transient psychological reactions to adversity and loss. These require a basic, supportive psychosocial response. 5 Yet, when these reactions interfere with daily functioning – as is the case when people develop associated symptoms of insomnia, enuresis or hyperventilation – general health-care providers (e.g. non-specialized physicians, clinical officers and nurses) need to know how to manage this. Second, common mental disorders, such as depression, post-traumatic stress disorder, and prolonged grief disorder, may be triggered by extreme stressors (e.g. trauma and loss). These disorders may become chronic and undermine the functioning of individuals and communities , which is essential for their survival and socioeconomic recovery. Health-care providers need to know how to manage these problems and how to distinguish mental disorders from widespread emotional distress that is common in emergency settings. 6 Third, pre-existing chronic psy-choses, bipolar disorder, intellectual disability and epilepsy can cause significant vulnerability in the chaos of an emergency. People with these conditions are at particular risk of neglect, aban-donment, abuse, interruption of maintenance medication and lack of access to health services. Moreover, triggered by the stress of adversity, people with a history of severe mental disorder may experience a relapse or exacerbation of existing symptoms. 7 Finally, acute health risks and social problems due to alcohol and drug use can be magnified in humanitarian settings ; 8 health-care providers need to be able to manage harmful use of alcohol and drugs as well as life-threatening withdrawal. 5 There is consensus that humanitarian assistance should address mental health and psychosocial issues …
