In Ghana, the main burden of ill-health, as in many sub-Saharan countries, consists of communicable disease, illnesses due to inadequate nutrition and poor reproductive health. As these conditions are tackled, other diseases, such as mental disorders and substance misuse, are also becoming the focus of development efforts. In Ghana, it has been estimated that there are 2166 000 individuals experiencing a mild to moderate mental disorder, with a further 650000 suffering from a severe mental disorder, out of a population of 21.6 million (World Health Organization, 2007). In 2003, the country's mental health workforce consisted of 9 psychiatrists (only 4 of whom worked in mental health services), 451 nurses and 160 community psychiatric nurses (World Health Organization, 2003). Currently there are just 5 consultant psychiatrists in active service in the public sector and 11 retired psychiatrists. As just under 33 000 individuals are seen each year in Ghana by mental health services, there is an estimated treatment gap of 98% (World Health Organization, 2007). Most mental healthcare is undertaken at the three large psychiatric hospitals, in the south of the country. This is reflected in the ratio of out-patient attendance to admission, which is 4.64 for mental health, compared with 14.6 for all health conditions (Ghana Health Service, 2005).
