Summary
Asthma care quality was assessed using indicators in Saskatchewan. Results show suboptimal management, with many patients not receiving adequate inhaled corticosteroids, highlighting a need for guideline-adherent treatment.
Area of Science:
- Pulmonary Medicine
- Health Services Research
- Epidemiology
Background:
- Asthma significantly burdens healthcare systems globally.
- Effective asthma management is achievable in most cases.
- Quality-of-care indicators are crucial for monitoring and improving asthma management.
Purpose of the Study:
- To evaluate the quality of asthma care in Saskatchewan using a defined set of quality indicators.
- To identify specific areas of suboptimal asthma management within the studied population.
Main Methods:
- A retrospective cross-sectional study utilizing Saskatchewan health databases (population ~1 million).
- Assessment of six quality-of-care indicators for asthma patients aged 5-54.
- Statistical analysis included crude/adjusted rates, confidence intervals, chi-squared tests, and generalized linear modeling.
Main Results:
- Prevalence of asthma was 3.8% (24,616 individuals aged 5-54) in 2002/03.
- 18% of asthma patients experienced poor symptom control.
- Among patients with poor control, 37% received no inhaled corticosteroids (ICS), and 40% received inadequate ICS doses.
- High ICS doses with other preventer use occurred in 26% of poorly controlled patients.
- Asthma hospital admissions were highest in children (6-9 years) and adult females (20-44 years).
- Males and adult age groups (20-44 years) showed poorer quality of care across four indicators.
Conclusions:
- Suboptimal asthma management identified, particularly concerning ICS and preventer medication use.
- Increased utilization of inhaled corticosteroids and preventer medications is recommended.
- Reduced reliance on short-acting beta-agonists is necessary to align with consensus guidelines for improved asthma control.
