Learning from low income countries: mental health

Prevention of mental illness by social support

Pathways to care in high income countries usually neglect community services and factors in operation before statutory care is sought. The development of provision of traditional care is an area where high income countries can learn from lower income countries. Although traditional care often reflects a lack of resources rather than an active choice, medical care does not always produce better outcomes. An example is the prevention of postpartum depression, which occurs in 10-20% of women in the United Kingdom and United States but is considered rare in Chinese populations, Fiji, and some African populations.3 Postpartum depression has an important effect on the mother's occupational and social function, bonding with her child, suicide, homicide, and burden on the family. Social support is considered important in prevention.3

Structured social supports after childbirth are described in groups of women with low rates of postpartum depression.3 In traditional Chinese society, women's bodies are considered weak in the month after childbirth, and the mothers are prohibited from working and visiting. Extra help is brought in—often it is the woman's mother or mother in law who helps with domestic duties, looks after the family, and offers advice.3 Studies in Hong Kong show lower levels of depression at three months in women who have this support.3 The rate of depression seems, however, to depend on who offers the support and whether this leads to conflict with the mother.4

In Fiji, new mothers are given intensive social supports and mandated relief from domestic duties (3-4 months) and work on family farms (12 months).3 In addition, a close female family member assists with the care of the newborn and other infants. The local community prepares food for the household. This support has also been linked to lower rates of postpartum depression.3

It would be hard, intuitively, not to come to the conclusion that traditional support offers benefit, but better evidence may be required by high income countries. Perhaps the central message is that external care should be focused on the mother, not the baby. Increasing care for new mothers would not require huge cultural changes. A study in the UK's West Midlands health region found a significantly decreased rate of postpartum depression when care was redesigned to focus on the needs of the mother.5

The response does not have to be service led. Governments could increase the pool of social support available to mothers. Perhaps paid leave from work to support mothers could be extended to grandparents or family members outside the nuclear family. Rich countries could consider longer periods of maternity leave and changes in financial packages to decrease the economic pressures to return to work.

The aim is not to transfer social responsibilities from the state to families and communities but to share the wealth of a nation to facilitate social support and give mothers and their families a safer financial environment in which to make choices. Given the economic and social impact of postnatal depression, with little evidence that current strategies decrease the rates of illness, employing some of the remedies from traditional paradigms may be cost effective.

Primary care response to depression

Worldwide, depression is one of the four main causes of life years lost to illness and the main non-fatal cause of disease.6 Care for depression in many developed countries is poorly coordinated and so often ineffective. Depression is commonly managed by primary care physicians, who have variable knowledge and interest in dealing with it. Many doctors who treat depression have no formal postgraduate training in psychiatry. Patients from the poorer areas of rich countries are less likely to receive effective treatment.

Structured models that aim to provide acceptable, simple, low cost but effective treatment for depression have emerged from low income countries. For instance, a recent randomised controlled trial in Santiago, Chile, reported on an effective, coordinated stepped care approach to treating depression.7 This multicomponent intervention was led by a non-medical health worker and included group psychoeducation about depression, systematic monitoring of symptoms, and a structured drug programme for those with more severe or persistent depression. At six months, 70% of the stepped care group had recovered. This study, and others in the developed world, have shown that small investments in the treatment of depression can have a huge impact, especially in socially deprived populations.8 This message has influenced decision makers, and the stepped care approach is now used to treat depression in primary care in Chile.9

The structured approach facilitated an increased role for non-medical staff and patients. One of the outcomes of the programme was greater patient involvement, and in some places women's groups started by the programme were still functioning after two years. The outcomes would be considered good for many inner city areas in high income countries. Clearly, however, the development of structured programmes may be easier in places where there are fewer services and vested interests.

Secondary care in non-traditional settings

Jamaica has developed innovative responses to the burden of care of those with severe mental illness. One innovation has been to treat people with psychiatric problems on acute general hospital wards.10 The rationale was that if acute psychosis and other presentations of mental distress were emergencies then clinicians on medical wards should play their part. Those admitted to the ward rather than a psychiatric hospital had a shorter hospital stay and better compliance with treatment, leading to employment. As this was a naturalistic study, the results should be treated with caution.

From secondary care to community care

India has developed the community based rehabilitation model. This comprises three tiers in which outpatient care (first tier) is supplemented with help from community case workers (second tier) and community rehabilitation initiatives (third tier).11 Case workers are drawn from the populations they are going to serve, and offer a service to users, their families, and communities. Initiatives are planned in a forum called a village health group, which includes carers and key local stakeholders. Compared with outpatient treatment, the community based rehabilitation model leads to better outcomes for disability, compliance, and engagement with treatment.11 The development of local health groups that focus on rehabilitation could offer a model to help deal with stigma, social exclusion, and community involvement.

Conclusion

We have provided some examples at different levels of the pathway to care and prevention of mental illness where the developed world could learn from the developing world. High income countries considering such developments would have to make them fit for purpose in a different social and economic environment. The issue of sustainability also arises. Community based support after childbirth has a long history, and medical ward care for psychiatric emergencies in Jamaica has been used for 30 years, but the stepped care approach and community based rehabilitation model are relatively new initiatives.

It could be argued that all these models use the least possible healthcare resources. With fewer resources the community may be empowered to take on more responsibilities for ill people. Some may see this as a positive development, but others may see such initiatives as a way of transferring state responsibilities to the population. If there were to be such a diversification in provision of care in the developed world then it would be hoped that resources would follow responsibility.

The development of sufficient open access psychotherapeutic groups for depression as part of a stepped care approach, or the changes in tax and benefits required for increased support to new mothers, may only be cost neutral if they are balanced against the costs of poorly or untreated depression. If these initiatives represented a decrease in service quality or outcome, it would be difficult for developed countries to consider them.

In the developing world the poorest have no choice but to take what is offered. This is sometimes true of inner city areas in developed countries where novel cheaper healthcare initiatives are sometimes introduced. We understand the tension between value for money, innovation, and quality. We do not advocate the development of two tier healthcare systems in developed countries.

Of interest for developed countries is that when these simple models have been tested in the developing world they have been shown to be at least equally effective as more sophisticated and expensive ones. Moreover, whether through decreasing the cultural gulf between services and their recipients, increasing community involvement in health care, reinforcing preventive strategies, or developing more rational models of service delivery the examples that we have cited may offer added value.
