ABSTRACT Asthma is one of the most common chronic diseases and a major economical burden to families and health systems. Whereas efficacy of current therapeutical options has been clearly established, cost-effectiveness analysis of public health interventions for asthma control are scarce.
81 patients with severe asthma (12-75 years) joining a programme in a reference clinic providing free asthma medication were asked retrospectively about costs and events in the previous 12 months. During 12 months after joining the programme, information on direct and indirect costs, asthma control by lung function, symptoms and quality of life were collected. The information obtained was used to estimate cost-effectiveness of the intervention as compared to usual public health asthma management. Sensitivity analysis was conducted.
64 patients concluded the study. During the 12-months follow-up within the programme, patients had 5 fewer days of hospitalization and 68 fewer visits to emergency/non scheduled medical visits per year, on average. Asthma control scores improved by 50% and quality of life by 74%. The annual saving in public resources was US$387 per patient. Family annual income increased US$512, and family costs were reduced by US$733.
A programme for control of severe asthma in a developing country can reduce morbidity, improve quality of life and save resources from the health system and patients families.

    ABSTRACT: Despite increase in understanding of asthma patomechanisms the practical actions to lessen asthma burden in the communities are far behind of scientific knowledge. There are still reports of uderdiagnosis and poor treatment leading to repeated severe exacerbations, often demanding emergency care and hospitalisation, which cause most of the economic burden both for families and society. From the public health perspective, the key issue is to implement the best standards of care in every-day practice. The problems are different in high income compared to low- and middle-income countries, and the solutions have to be tailored to each country needs and resources. We present here examples from Finland, Poland and Brazil, to show that asthma burden can be reduced using varied strategies in quite different societal, economical and health care environments. The experience from those interventions confirms that regardless of the health care system and its coverage, a major change for the better can be achieved by local efforts, systematic planning and networking to implement the best asthma practice.

    ABSTRACT: Asthma is a chronic inflammatory disorder of the airways that is characterized by recurrent symptoms associated with airflow limitation and by bronchial hyper-responsiveness. Free asthma treatment has been guaranteed in Brazil since 2003, notably after the Brazilian government decided to support drugs for the most serious forms of the disease. The asthma treatment access policy in Brazil offers a new opportunity for pharmacists to work closely with patients, and for caregivers and health care teams to promote educational activities and patient counselling about asthma. Pharmacists have an important role in the management of drug therapy within the health care team. Pharmacists should be prepared to engage with the latest concept of health care delivery proposed for Brazilian Unified Health System. These are centred on forming health care networks and strengthening multidisciplinary teams to integrate all professionals who are in charge of patient care.

    ABSTRACT: the asthma morbidity statistics in the City. The reference center of the Program, in its initial first three years of functioning, assisted 3,504 patients. Children of less than 13 years old represented 53% of the total. Asthma was diagnosed in 44% of the patients, asthma and rhinitis in 32%, rhinitis only in 12%, and there were other diagnoses in 12%. A reduction of 42% in asthma hospitalizations was observed in Feira de Santana in the first year of ProAR's functioning, indicating a significant impact in asthma morbidity and, consequently, in the expenses of the Brazilian Health Public System with the disease.
