Background: Although universal health care aims for equity in service
delivery, socioeconomic status still affects death rates from ischemic
heart disease and stroke as well as access to revascularization procedures.
We investigated whether psychiatric status is associated with a similar
pattern of increased mortality but reduced access to procedures. We
measured the associations between mental illness, death, hospital
admissions and specialized or revascularization procedures for circulatory
disease (including ischemic heart disease and stroke) for all patients in
contact with psychiatric services and primary care across Nova Scotia.
Methods: We carried out a population-based record-linkage analysis of
related data from 1995 through 2001 using an inception cohort to calculate
rate ratios compared with the general public for each outcome (n = 215
889). Data came from Nova Scotia's Mental Health Outpatient Information
System, physician billings, hospital discharge abstracts and vital
statistics. We estimated patients' income levels from the median incomes of
their residential neighbourhoods, as determined in Canada's 1996 census.
Results: The rate ratio for death of psychiatric patients was significantly
increased (1.34), even after adjusting for potential confounders, including
income and comorbidity (95% confidence interval [CI] 1.29-1.40), which was
reflected in the adjusted rate ratio for first admissions (1.70, 95% CI
1.67-1.72). Their chances of receiving a procedure, however, did not match
this increased risk. In some cases, psychiatric patients were significantly
less likely to undergo specialized or revascularization procedures,
especially those who had ever been psychiatric inpatients. In the latter
case, adjusted rate ratios for cardiac catheterization, percutaneous
transluminal coronary angioplasty and coronary artery bypass grafts were
0.41, 0.22 and 0.34, respectively, in spite of psychiatric inpatients'
increased risk of death.
Conclusions: Psychiatric status affects survival with and access to some
procedures for circulatory disease, even in a universal health care system
that is free at the point of delivery. Understanding how these disparities
come about and how to reduce them should be a priority for future research.
