Background

Although many of the Small Island Development States (SIDS) are renowned as holiday destinations, they are not unscathed by the same mental health issues which affect other countries. Owing to the relatively small population sizes of SIDS – ranging from countries as small as Niue (population about 1200) to Jamaica with nearly 3 million people – and their remoteness, their mental health systems face many common difficulties, including the following.

• • Few mental health specialists owing to population size, high turnover and brain drain. Some of the countries have a population below 10 000, which makes it difficult to afford psychiatrists or mental health specialists.

• • Limited access to mental health services in countries with small, scattered islands. In some countries, mental health services are only available on the main island, which may take days or even weeks to reach from remote islands with infrequent transfers by boat.

• • Low mental health awareness, which leads to stigma and discrimination. Confidentiality is difficult to maintain, owing to the small population and closeness of community members; everybody knows everybody else.

• • Non-communicable diseases are a serious concern, leading to an increase in mental health issues.

• • High alcohol use owing to limited leisure activities, or to attract tourism. Gender-based violence is common and usually associated with alcohol misuse.

• • Vulnerability to climate change, especially related to the increase in natural disasters. Most recently, Fiji has been struck by Cyclone Winston, and Hurricane Matthew has hit several Caribbean countries and provoked serious damage in Haiti. Mental health and psychosocial support are needed for those affected.

However, there are also the following strengths.

• • Strong cultural bonding because of the relatively small population. Strong community solidarity and a strong sense of supporting each other.

• • Strong informal support, which compliments the weak formal social support in areas such as social security, housing services and disability pensions.

• • Availability of functioning basic health services via general hospitals, primary healthcare clinics and, in some countries, dispensaries. Most of the countries have a tax-based health system, similar to the British system. The government pays medical fees, including the cost of medicines, and provides services as part of a public system.

Because of these limitations and strengths, the World Health Organization (WHO) Mental Health Gap Action Programme (mhGAP) (WHO, 2008), which aims to decrease the treatment gap by training non-specialists, is the obvious strategy for SIDS. mhGAP is a programme developed by WHO, which aims to increase mental health service coverage and to reduce the gap between needs and supply. The programme was launched in 2008, and its clinical protocol to assess and manage priority mental disorders and conditions, the mhGAP Intervention Guide (mhGAP-IG), was developed in 2010 (WHO, 2010). A second version was revised and released in 2016 (WHO, 2016). mhGAP-IG targets non-specialist health workers, mainly doctors and nurses who do not specialise in mental health. Since then, more than 90 countries across the world have implemented mhGAP, including more than 20 SIDS.

Here, we will describe examples of mhGAP implementation in the Pacific and the Caribbean regions, then discuss lessons learned and the way forward.

mhGAP implementation

Example from the Pacific

Implementation of mhGAP in the Pacific island countries started with an in-country planning workshop to which key mental health stakeholders were invited. During the workshop, stakeholders discussed various topics related to mhGAP implementation, such as who to train, who the trainer will be, who the supervisor will be, establishing support and a supervision system, ensuring drug availability at the target facilities, and monitoring and evaluation of the whole process. Adaptations of mhGAP implementation to the local context, such as which conditions and medications to train in as a priority, and what the consultation and referral pathways will be, were also discussed. Cultural adaptation was usually addressed through the training. Depending on the priority of the country and number of training days, the sessions usually focused on the modules for depression, psychosis, alcohol, suicide, and other significant emotional or medically unexplained complaints.

For larger countries, a ‘training of the trainers’ (ToT) model was applied, in which mental health specialists were to become mhGAP trainers. The mhGAP training programme developed by WHO is designed to be interactive, using discussions, case studies, roleplays and videos. The first mhGAP training in each country was completed by a combination of international and local facilitators, and then rolled out by local facilitators, depending on the country's capacity and needs.

Three mhGAP ToTs were conducted in the Pacific: two in Fiji with participants from Kiribati, Tonga and Vanuatu, and one in Guam with participants from the Marshall Islands, Federated States of Micronesia, Palau and Northern Mariana. So far, 14 countries have initiated mhGAP and trained more than 900 doctors and nurses (Fig. 1). Pre- and post-training tests showed remarkable improvement in knowledge, and the trainees showed confidence in assessing and managing people with mental disorders after completing the training.

Learning from the Caribbean experience (below), an online version of the training is planned for 2017, mainly targeting busy medical doctors.

Lessons learned and the way forward

From implementation of mhGAP in more than 20 SIDS, many lessons have been learned regarding the way forward. We will discuss a few of the most important ones.

Mental health specialist support is crucial. Each mhGAP trainee will be trained to assess and manage common mental disorders, but will need a mental health specialist who can support, supervise, continue to train and be a reference for the more difficult cases. Online training and supervision could be one solution to this problem.

mhGAP training has been proved to be effective to improve the trainees' knowledge and attitudes towards people with mental disorders, but close monitoring and supervision is needed to change their clinical practice.

It is crucial to raise awareness on mental health and also on the availability of mental health services to increase help-seeking behaviour. Awareness raising and mental health service capacity building need to go hand in hand.

Weak health information systems make monitoring and evaluation difficult. There is a need to integrate and strengthen health information systems, and to report on a core set of mental health indicators.

Mental health has been included in Sustainable Development Goals (United Nations 2016); for example, target 3.4 states: ‘By 2030, reduce by one third premature mortality from non-communicable diseases through prevention and treatment and promote mental health and well-being’. Target 3.c recommends an increase in the health workforce in SIDS: ‘Substantially increase health financing and the recruitment, development, training and retention of the health workforce in developing countries, especially in least developed countries and small island developing States’. To realise these targets by 2030, countries need to invest more in mental health, especially in human resources. Mental health services do not require expensive equipment, but they do need more trained human resources. mhGAP is one effective solution, but there is also need to increase human resources at all levels – specialists, non-specialists and community/village health workers.
