Objective: To evaluate the agreement between the criteria used for hospitalization of patients with communityacquired pneumonia (CAP) and those of the Brazilian Thoracic Association guidelines, and to evaluate the association of that agreement with 30-day mortality. Secondarily, to evaluate the agreement between the treatment given and that recommended in the guidelines with length of hospital stay, microbiological profile, 12-month mortality, complications, ICU admission, mechanical ventilation, and 30-day mortality. Methods: This was a retrospective study involving adult patients hospitalized between 2005 and 2007 at the Federal University of Minas Gerais Hospital das Clínicas, located in Belo Horizonte, Brazil. Medical charts and chest X-rays were reviewed. Results:Among the 112 patients included in the study, admission and treatment criteria were in accordance with the guidelines in 82 (73.2%) and 66 (58.9%), respectively. The 30-day and 12-month mortality rates were 12.3% and 19.4%, respectively. The 30-day mortality rate was lower for patients in whom the CRB-65 (mental Confusion, Respiratory rate, Blood pressure, and age ≥ 65 years) score was 1-2 and the antibiotic therapy was in accordance with the guidelines (p = 0.01). Cerebrovascular disease and appropriate antibiotic therapy showed independent associations with 30-day mortality. There was a trend toward an association between guidelineconcordant antibiotic therapy and shorter hospital stay. Conclusions: In the population studied, admission and treatment criteria that were in accordance with the guidelines were associated with favorable outcomes in hospitalized patients with CAP. Cerebrovascular disease, as a risk factor, and guideline-concordant antibiotic therapy, as a protective factor, were associated with 30-day mortality.Keywords: Pneumonia/therapy; Pneumonia/mortality; Hospitalization; Guideline adherence. ResumoObjetivo: Avaliar a concordância entre os critérios de hospitalização utilizados para a admissão de pacientes com pneumonia adquirida na comunidade (PAC) e aqueles da Sociedade Brasileira de Pneumologia e Tisiologia e avaliar a associação dessa concordância com a taxa de mortalidade em 30 dias. Secundariamente, avaliar a associação da concordância entre o tratamento instituído e as recomendações dessas diretrizes com duração da internação hospitalar, investigação microbiológica, mortalidade em 12 meses, complicações, internação em UTI, ventilação mecânica e mortalidade em 30 dias. Métodos: Estudo retrospectivo que incluiu pacientes adultos internados entre 2005 e 2007 no Hospital das Clínicas da Universidade Federal de Minas Gerais, na cidade de Belo Horizonte (MG). Foram revisados prontuários e radiografias de tórax. Resultados: Dentre os 112 pacientes incluídos, os critérios de internação e de tratamento foram concordantes com as diretrizes em 82 (73,2%) e 66 (58,9%), respectivamente. A taxa de mortalidade em 30 dias e em 12 meses foi de 12,3% e 19,4%, respectivamente. Pacientes com escore de CRP-65 (Confusão mental, frequênci...

The results show that the majority of non-specialized physicians working within the public health care system do not manage the treatment of patients with asthma in accordance with the guidelines. This situation calls for continuing medical education programs that prioritize primary care.

Objective: To evaluate whether the use of inhaled albuterol via a metered-dose inhaler with a large-volume spacer with antistatic treatment modifies the bronchodilator test results when compared with the usual technique (no spacer). Methods: A prospective study involving 24 patients, 18-45 years of age, clinically suspected of having asthma, and under treatment at the Outpatient Pulmonary Clinic of the Federal University of Minas Gerais Hospital das Clínicas, located in the city of Belo Horizonte, Brazil. All of the patients underwent two bronchodilator tests: one with and one without the use of a large-volume spacer. Results: There was no significant difference in the variation of FEV 1 prior to and after bronchodilator use between the two techniques (mean ΔFEV 1 = 0.01 L; 95% CI: −0.05 to 0.06; p = 0.824). No statistically significant difference was found between the two techniques regarding the qualitative results on the bronchodilator test (p = 1.00). There was concordance between the techniques in terms of the bronchodilator test results (kappa coefficient = 0.909; p < 0.005). Conclusions: According to the results of this study, the use of large-volume spacers does not significantly modify bronchodilator test results.Keywords: Asthma; Spirometry; Inhalation spacers. ResumoObjetivo: Avaliar se o uso de salbutamol inalatório através de inalador dosimetrado acoplado a espaçadores de grande volume com tratamento antiestático na espirometria com prova broncodilatadora modifica os resultados do teste quando comparado à técnica usual (sem espaçador). Métodos: Estudo prospectivo envolvendo 24 pacientes, com idades entre 18 e 45 anos e suspeita clínica de asma, atendidos no Ambulatório de Pneumologia do Hospital das Clínicas da Universidade Federal de Minas Gerais, em Belo Horizonte (MG). Os pacientes foram submetidos a duas espirometrias com prova broncodilatadora realizadas com e sem o uso de espaçador de grande volume. Resultados: Não houve diferença significativa na variação do VEF 1 antes e após o uso de broncodilatador entre as duas técnicas (ΔVEF 1 média = 0,01 L; IC95%: −0,05 a 0,06; p = 0,824). Não houve diferença estatisticamente significativa entre as duas técnicas em relação ao resultado qualitativo da prova broncodilatadora (p = 1,00). Houve concordância dos resultados da prova broncodilatadora entre as técnicas (coeficiente kappa = 0,909; p < 0,005). Conclusões: De acordo com os resultados deste estudo, a utilização de espaçadores de grande volume não modificou de forma significativa os resultados da prova broncodilatadora.Descritores: Asma; Espirometria; Espaçadores de inalação.
