Abstract
BACKGROUND
Although the ultimate goal of asthma treatment is to improve asthma-specific Health-Related Quality-Of-Life (HRQOL), in the UK population this is insufficiently studied. National asthma-specific HRQOL data is needed to inform strategies to address this condition.
AIMS AND OBJECTIVES
To benchmark asthma-specific HRQOL in a national survey of adults with asthma, and explore differences in this measure within subsections of the population.
METHODS
We analysed answers to the Marks Asthma Quality-of-Life Questionnaire (AQLQ-M) from a representative sample of 658 adults with asthma. Respondents answered asthma-specific questions to assess control, previous hospital admissions, asthma attacks and an indicator of severity. Higher scores indicate poorer HRQOL (maximum = 60). The highest quintile formed a subgroup 'Poor HRQOL'. Data were weighted to correct for any biases caused by differential non-response. Chi-square analyses were used to determine differences between good and poor quality of life and regression analyses performed to determine what factors are associated with poor HRQOL.
RESULTS
The response rate was 49%. AQLQ-M median (IQR) scores were 5 (2-13) for the total sample (poor HRQOL = 21, good HRQOL = 3). Significant differences between good and poor HRQOL were observed in smoking status, SES, employment status and co-morbidities, but no differences were found between age groups. Those with poorly controlled asthma were significantly more likely to have poor HRQOL, ≥1 breathing related hospital admission or ≥1 asthma attack.
CONCLUSIONS
This article provides benchmarking data on asthma-specific HRQOL. Improved strategies are needed to target interventions towards people experiencing poor HRQOL.
