Impacto de uma intervenção educacional de curta duração sobre a adesão ao tratamento e controle da asma

OBJECTIVE To evaluate the effect of a short-term individualized education program on adherence to asthma treatment, inhalation techniques, and asthma control. METHODS A prospective study involving patients aged 14 years or older, with a confirmed diagnosis of asthma and recruited from the asthma outpatient clinic of a university hospital in the city of Porto Alegre, Brazil. The study was conducted in two phases (before and after the educational intervention). At a routine medical visit, the participants completed a general questionnaire in order to assess the level of asthma control and inhalation techniques. The participants also underwent pulmonary function testing. Subsequently, they participated in an asthma education program, which consisted of one individualized session. The participants were reevaluated after three months. RESULTS Of the 174 patients recruited, 115 completed the study. Between the first and second evaluations, there was a significant improvement in the effective use of inhaled corticosteroids (90.4% vs. 93.3%; p = 0.003), the effective use of long-acting β2 agonists (57.4% vs. 63.5%; p < 0.0001), the effective use of a combined regimen with these two medications (57.4% vs. 62.6%; p < 0.0001), and the self-reported adherence to corticosteroid therapy (p = 0.001). There was a significant decrease in the proportion of patients visiting ERs (30.4% vs. 23.5%; p = 0.012). However, the level of asthma control and the inhalation technique did not improve significantly (p = 0.095 and p = 0.512, respectively). CONCLUSIONS This short-term asthma education program resulted in an improvement in the use of medications for asthma control and a decrease in the number of ER visits, although it had no significant effect on the inhalation technique.

Respiratory viral infections and effects of meteorological parameters and air pollution in adults with respiratory symptoms admitted to the emergency room

Respiratory viral infections (RVIs) are the most common causes of respiratory infections. The prevalence of respiratory viruses in adults is underestimated. Meteorological variations and air pollution are likely to play a role in these infections.

Perfil epidemiológico dos atendimentos de emergência por sintomas respiratórios em um hospital terciário

OBJECTIVE: To evaluate the prevalence of respiratory symptoms as the motive for emergency room visits by adult and pediatric patients, describing the major clinical syndromes diagnosed and the outcomes of the patients. METHODS: A cross-sectional study conducted in the emergency room of a tertiary care university hospital. Between November of 2008 and November of 2009, we reviewed the total number of emergency room visits per day. Children and adults who presented with at least one respiratory symptom were included in the study. The electronic medical records were reviewed, and the major characteristics of the patients were recorded. RESULTS: During the study period, there were 37,059 emergency room visits, of which 11,953 (32.3%) were motivated by respiratory symptoms. The prevalence of emergency room visits due to respiratory symptoms was 28.7% and 38.9% among adults and children, respectively. In adults, the rates of hospitalization and mortality were 21.2% and 2.7%, respectively, compared with 11.9% and 0.3%, respectively, in children. Among the adults, the time from symptom onset to emergency room visit correlated positively with the need for hospitalization (p < 0.0001), the length of the hospital stay (p < 0.0001), and the mortality rate (p = 0.028). CONCLUSIONS: We found a high prevalence of respiratory symptoms as the motive for emergency room visits by adult and pediatric patients. Our results could inform decisions regarding the planning of prevention measures. Further epidemiological studies are needed in order to clarify the risk factors for severe respiratory symptoms.
