An index condition or disease describes the main condition under study (Ording and Sørensen 2013). Related terms, such as dual diagnosis and multimorbidity, are used in various clinical and research settings. Dual diagnosis is usually defined specifically as coexisting mental illness and substance or alcohol use disorders. Multimorbidity refers to the co-occurrence of multiple chronic or acute conditions in one person without identifying an index condition (Valderas et al. 2009). Depending on the setting and application of the concept, such as in clinical care, epidemiology, or health services planning and finances,...
