Pharmaeconomics in asthma

[Healthcare resources for asthma management at primary care level: Asthmabarometer Project]

OBJECTIVE

The objective of this study was to describe the current provision of basic resources for asthma management in Primary Health Care (PHC).

DESIGN

Cross-sectional study, with an ad hoc quantitative survey.

LOCATION AND PARTICIPANTS

A total of 380 primary healthcare physicians in Spain.

INTERVENTIONS AND MAIN MEASUREMENTS

Analysis of perceptions of management and use of basic human, organisational and material resources to ensure appropriate care provision to asthma patients.

RESULTS

Survey respondents stated that their centre did not have a consultant doctor (64%) or nurse (62%) in respiratory disease. Almost all (92%) of the centres have spirometers, of which 70% have peak flow meters, and 93% have placebo inhalers. In the last year, respondents have received specific theoretical/practical training from the centre (46%), and by third parties (83%). More than three-quarters (78%) of the centres has educational material available for patients. There is no specific healthcare protocol in 36% of the centres, and 43% had no referral protocol. A clinical interview is conducted to monitor the patient (90%), but there are no validated questionnaires to measure therapeutic adherence (85%), or a checklist to check inhalation technique (83%). Differences are observed in the relevant variables in the analysis of each Spanish Autonomous Community.

CONCLUSIONS

Access to certain resources in the care of patients with asthma is limited in aspects of coordination between levels, varied according to Spanish Autonomous Community, and improved in most health resources in Asthma.

Cost of asthma in Portuguese adults: A population-based, cost-of-illness study

INTRODUCTION

Asthma is one of the most frequent chronic diseases, putting a considerable economic burden on societies and individuals. We aimed to estimate the total cost of adult asthma in Portugal, as well as the extent to which direct and indirect costs are influenced by the level of asthma control.

METHODS

A nationwide, prevalence-based, cost-of-illness study using a bottom-up approach to calculate direct and indirect costs of asthma was conducted, using participant data from the Portuguese National Asthma Survey (INAsma). Direct (healthcare service usage, diagnostic tests and treatment) and indirect (absenteeism and transportation) costs were measured. Decision analytic modelling was used to perform multivariate deterministic sensitivity analysis.

RESULTS

On average, each adult costs 708.16€ (95%CI: 594.62-839.30) a year, with direct costs representing 93% (658.46€; 95%CI: 548.99-791.29) and indirect costs representing 7% (49.70€; 95%CI: 32.08-71.56). This amounts to a grand total of 386,197,211.25€ (95%CI: 324,279,674.31-457,716,500.18), with direct costs being 359,093,559.82€ (95%CI: 299,391,930.03-431,533,081.07). Asthma direct costs are 2.04% of the total Portuguese healthcare expense in 2010. The major cost domains were acute care usage (30.7%) and treatment (37.4%). Asthma control was significantly associated with higher costs throughout several domains, most notably in acute medical care.

CONCLUSIONS

Asthma in adults poses a significant economic burden on the Portuguese healthcare system, accounting for over 2% of the total healthcare expenditure in Portugal in 2010. It is important to note that a considerable portion of this burden might be eased by improving asthma control in patients, as uncontrolled patients' costs are more than double those of controlled asthma patients.
