Abstract [en]

AIM: To compare the degree of asthma control in 2001 and 2005 in a primary care setting in Sweden. METHOD: Two similar questionnaire surveys were performed in 2001 and 2005 with 1,012 and 224 asthma patients aged 18-45 randomly selected from 42 and 56 primary health care centres, respectively. A classification of asthma control similar to the GINA guidelines was made using information obtained from the questionnaire. RESULTS: In 2001, 36.6% had achieved asthma control, 23.8% were partly controlled and 39.6% uncontrolled. In 2005, the corresponding figures were 40.2%, 26.8% and 33.0%, respectively, with no difference between the two surveys (p=0.114). Uncontrolled asthma was more common in women (p<0.001 in the first and p<0.05 in the second survey) and smokers (p<0.01 in the first and p<0.01 in the second survey). The use of combination corticosteroid/long-acting bronchodilator inhalers had increased - 34.2% and 48.2%, respectively (p<0.001) - and many patients used their inhaled corticosteroids periodically. CONCLUSION: In spite of treatment guidelines many patients in Swedish primary care still have insufficient asthma control.

Abstract [en]

Aims. The overall aim was to examine the severity, treatment and level of control in patients with asthma in primary care in Sweden. The specific aims were to assess what matters to asthma patients, evaluate symptoms, medication and identify factors related to asthma severity, compare the extent of asthma control in 2001 and 2005, and investigate the development of asthma and degree of asthma control in adolescents and young adults who had reported asthma six years earlier.

Methods. The first study was a telephone interview of a representative sample of Swedish asthmatics. In the second study a random sample of 1,136 patients answered two questionnaires. A classification of the asthma severity similar to that in the GINA guidelines was made. In the third study two surveys were performed, in 2001 and in 2005, with a random sample of 1,012 and 224 asthma patients, respectively, and a classification of asthma control similar to the recent GINA guidelines was made. In the fourth study 71 individuals who reported physician-diagnosed asthma in a population-based survey in 1997 and were defined as current asthmatics, were reinvestigated in 2003 with a skin prick test, methacholine challenge test, eucapnic voluntary hyperventilation test and measurement of exhaled nitric oxide.

Results. Common situations causing symptoms of asthma were physical exertion and contact with pets. Nocturnal symptoms were frequent. In primary care 35% of the women and 24% of the men were classified as having severe asthma. Female sex, increasing age, not filling the asthma prescription owing to cost, daily smoking, and pollen allergy increased the odds of having severe asthma. In 2001, 37% had achieved asthma control, as compared with 40% in 2005. Uncontrolled asthma was more common in women and smokers. In the 2003 study of adolescents and young adults with asthma six years earlier, the definition of current asthma was fulfilled by 50 of the 71 subjects and one third had achieved asthma control.

Conclusions. The majority of the asthmatics reported a large number of symptoms and limitations in their daily living. Many asthma patients in primary care have insufficient asthma control. One reason for lack of control might be undertreatment with inhaled corticosteroids.
