Such patients are disproportionately represented among populations that are socioeconomically deprived and elderly.1 A socioeconomic gradient exists in the incidence and prevalence of almost all major categories of disease, meaning that individuals and families who are socioeconomically disadvantaged are at risk of a compounding multiplicity of health and social problems.2 This multiple morbidity, coupled with the fact that the population of the United Kingdom is ageing,3 poses challenges to the delivery of effective health care that have received almost no official attention.

    Examples from mental health show that provision of service in this field has been slow to move from single diagnosis to dual diagnosis.4 Dual diagnosis applies to patients who have a mental health problem and problematic substance or alcohol use. A recent report on dual diagnosis from the Department of Health highlighted the role that primary care had in ensuring adequate care pathways for patients with mental health problems, drug problems, and related physical problems such as infection with hepatitis B or C virus or HIV.2 The report highlighting the issue of dual diagnosis did not use the term “multiple morbidity” to describe these patients. We believe, however, that such a term accurately describes the multitude of health need.
