Use of anti-asthmatic drugs in Italy: analysis of prescriptions in general practice in the light of guidelines for asthma treatment

The level of control of mild asthma in general practice: an observational community-based study

OBJECTIVE

The aim of the present community-based study was to evaluate the level of asthma control in patients with mild asthma, regularly treated with inhaled steroids (ICS).

METHOD

This observational cross-sectional study included patients registered in the general practitioner (GP) database and with at least three prescriptions of ICS in the last 12 months. Patients were asked to refer to the doctor's office for a standardised interview. The level of asthma control was self-measured by the patients using the Asthma Control Test (ACT)™ (Quality Metric, Inc.).

RESULTS

The study included 950 asthmatic patients, referred by 540 GPs: 54.5% were females, mean age was 51 (±19.1) years; 59.5% were non-smokers, 22.5% were current smokers and 18.0% were former smokers; 81.1% of the patients were on ICS in the last 4 weeks. Only 38.6% of patients had a spirometry in the last 12 months. According to the ACT, 13.7% of the asthmatic patients were totally controlled, 51.0% well controlled, and 35.3% poorly controlled. Smoking habit, older age (>60) and living in Central or Southern Italy were associated with poorer control. In the last 12 months 4.5% of patients had an asthma-related hospitalisation, 5.3% an emergency visit and 18.9% a specialist visit.

CONCLUSIONS

More than one of three patients had poor asthma control, despite being considered by their GPs as mild asthmatics and treated with ICS. Asthmatic patients need to be regularly re-evaluated. Treatment is often inadequate and should be targeted to improve control and reduce asthma morbidity (SAM104964).

Assessing paediatric asthma occurrence through dispensed prescription data and questionnaires

BACKGROUND

The prevalence of asthma, a common disorder in childhood, is often estimated by cross-sectional studies based on questionnaires, with the drawback that estimates are limited to certain age groups and areas. The use of electronic health data is increasingly allowing researchers to overcome these limitations. This study is aimed at assessing asthma occurrence of a school-aged population in Northeast Italy using two different data sources.

METHODS

In 2004, a population-based survey using a standardized questionnaire was conducted to estimate asthma occurrence among a resident population of children aged 6-7 years and adolescents aged 13 years. A selection of dispensed asthma medications was extracted from electronic databases for a 4-year period prior to questionnaire completion (2000-03). Asthma prevalence was estimated by commonly used questionnaire classifications and compared with use of inhaled bronchodilators (alone or in combination) in various time periods. Correlations between the two approaches were calculated.

RESULTS

A total of 10 252 subjects were eligible for analysis (85% of the resident population). A total of 4747 subjects (38% of the resident population) were registered in the drug database during 2000-03. Asthma prevalence was higher in males and in children. Congruence between the two enquiry methods varied according to criteria applied and improved with the protraction of the observation period.

CONCLUSION

A longer period for the capture of medication data yielded higher congruence. A degree of mismatch was observed between the two methods most likely related to factors of drug use and questionnaire reliability. Nonetheless, the benefits of using easily accessible population data prevail, and further studies are warranted.

Impact of 'mild' asthma on health outcomes: findings of a systematic search of the literature

The present bibliographic review shows that patients considered to have mild asthma often suffer impairment in quality of life (QoL) and use considerable scheduled and unscheduled health care resources. I found that asthma investigators used no consistent classification scheme for asthma severity, and the level of agreement amongst specialists when categorizing patients with asthma was low. Asthma severity has been classified using a wide range of parameters including medication use, asthma symptoms, lung function, hospitalizations and incidence of exacerbations. Most studies showed a general association between asthma severity and health-related quality of life (HRQoL) such that patients with severe disease suffered greater impairment. However, few patients with mild asthma enjoyed unimpaired HRQoL. Indeed depression and impaired HRQoL were reported as frequently in patients with mild asthma as in those with more severe disease. Although in general severe patients used the most health care resources, even patients with mild asthma used considerable health care resources including emergency room care and hospitalizations. In summary, the term 'mild' when applied to asthma is potentially misleading given the impaired HRQoL and avoidable health care utilization prevalent amongst such patients. The application of disease severity classification in clinical asthma management has not been validated. It may now be appropriate to examine these classifications more critically in order to determine if they have clinical or research usefulness. By contrast, the strategy of treating to achieve disease control has been validated and offers the advantage of simplicity in its application.

Achievements and shortcomings of Finnish asthma care

BACKGROUND

The Finnish National Asthma Programme was launched in 1994.

AIM

A postal self-completion questionnaire study was undertaken to evaluate how the guideline is working in the Finnish healthcare system.

METHODS

A postal inquiry was sent to a random sample of 6,000 subjects aged 16+ years who were entitled to special reimbursement for anti-asthmatic medication and 4,657 subjects with self-reported asthma were included.

RESULTS

The subjects comprised 38% men (n=1,781) and 62% women (n=2,876). In all, 62% of all the subjects and 78% of those with severe asthma had visited a doctor on account of asthma in the past 12 months. Some 83% of the respondents had a given physician who was responsible for treating their asthma, and 75% of these were under observation by a primary healthcare physician. Visits to asthma nurses were relatively rare. Inhaled glucocorticoids were used by 83% of the subjects, but short-acting beta-2-agonists were still the most commonly used asthma drug in monotherapy regardless of the severity of asthma. Inhaled glucocorticoids and a short-acting beta-2-agonist was the most frequent combination. Every tenth subject used this combination supplemented by a long-acting beta-2-agonist.

CONCLUSION

Asthma care in Finland seems to be compatible with the national guidelines in terms of continuity and the common use of inhaled glucocorticoids. The primary care sector has adopted the main responsibility for the treatment of asthma. The common use of short-acting beta-2-agonists is an exception to an otherwise positive trend.
