We assessed the associations between multimorbidity and health-related quality of life (HRQL), and healthcare utilization, based on 16 common self-reported chronic conditions.
A cross-sectional questionnaire survey including the EQ-5D was conducted in a sample of the general population of adults (≥18 years) living in Alberta, Canada. Multiple linear and logistic regressions were used to assess the association between multiple chronic conditions and HRQL, hospitalization and emergency department (ED) use.
A total of 4,946 respondents reported their HRQL, noting problems mostly with pain or discomfort (48.0 %). All chronic conditions were associated with a clinically important reduction in HRQL, the highest burden with anxiety or depression (−0.19, 95 % CI −0.21, −0.16) and chronic pain (−0.19, 95 % CI −0.21, −0.17). Multimorbidity was associated with a clinically important reduction in the EQ-5D index score (−0.12, 95 % CI −0.14, −0.11) and twice the likelihood of being hospitalized (OR = 2.2, 95 % CI 1.7, 2.9) or having an ED visit (OR = 1.8, 95 % CI 1.4, 2.2).
Pain or discomfort is a common problem in people living with chronic conditions, and the existence of multimorbidity in these individuals is associated with a reduction in the HRQL as well as frequent hospitalization and emergency department visits.
