Multimorbidity, health-related quality of life and health service use among individuals with mental health problems: Urban-rural differences in South Australia.

Abstract

To investigate urban-rural differences in the relationship between the coexistence of multiple physical health conditions, health-related quality of life and health service use among individuals with mental health problems. Cross-sectional. Population-based. Random sample of 2977 South Australians aged 15+years. Analyses restricted to 535 individuals self-reporting a "current" mental health problem (anxiety, depression, another mental condition). Number of physical health conditions (none, 1-2, 3+ conditions) based on a list of 16 self-reported chronic diseases. Physical and mental health-related quality of life, frequently visited a GP (3+ times), visited a mental health specialist, visited an emergency department, was hospitalised in the last 3months. The mean age of the participants was 57.3± 13.9 years (51.9% females) with 10.6% of them living ininner regional and 14.9% in outer/remote locations.Mental health problems had similar prevalence in major cities (15.4%; 95% confidence intervals [CI]: 13.5-17.4), inner regional (19.3%; 95% CI: 14.8-24.7) and outer/remote areas (16.8%; 95% CI: 14.4-17.7). The remoteness of residence did not affect the relationship between the number of physical health conditions with health-related quality of life or visits to the emergency department/hospitalisations. Individuals without a physical health condition living in major cities were five times more likely to have frequently visited a GP than their counterparts in outer/remote South Australia (35% and 7%, respectively), but these differences were less marked among those with multiple co-morbidities. The coexistence of multiple physical health conditions among patients with a mental health problem is associated with less urban-rural disparities in terms of visiting a GP.
