Unidirectional endobronchial valves for management of persistent air-leaks. Results of a multicenter study

Background: To evaluate the efficacy of Endo-Bronchial Valves in the management of persistent air-leaks (PALs) and the procedural cost. Methods: It was a retrospective multicenter study including consecutive patients with PALs for alveolar pleural fistula (APF) undergoing valve treatment. We assessed the efficacy and the cost of the procedure. Results: Seventy-four patients with persistent air leaks due to various etiologies were included in the analysis. In all cases the air leaks were severe and refractory to standard treatments. Sixty-seven (91%) patients underwent valve treatment obtaining a complete resolution of air-leaks in 59 (88%) patients; a reduction of air-leaks in 6 (9%); and no benefits in 2 (3%). The comparison of data before and after valve treatment showed a significant reduction of air-leak duration (16.2±8.8 versus 5.0±1.7 days; P<0.0001); chest tube removal (16.2±8.8 versus 7.3±2.7 days; P<0.0001); and length of hospital stay (LOS) (16.2±8.8 versus 9.7±2.8 days; P=0.004). Seven patients not undergoing valve treatment underwent pneumo-peritoneum with pleurodesis (n=6) or only pleurodesis (n=1). In only 1 (14%) patient, the chest drainage was removed 23 days later while the remaining 6 (86%) were discharged with a domiciliary chest drainage removed after 157±41 days. No significant difference was found in health cost before and after endobronchial valve (EBV) implant (P=0.3). Conclusions: Valve treatment for persistent air leaks is an effective procedure. The reduction of hospitalization costs related to early resolution of air-leaks could overcome the procedural cost

Cost comparison of two aerosol bronchodilator delivery methods in patients with acute asthma in the emergency department : intermittent nebulization versus metered-dose inhaler with valved spacer

Objetivo: A administração de broncodilatadores através de dispositivo com aerossol dosimetrado (spray) ou através de nebulizador é equivalente em eficácia no tratamento da asma aguda. Alguns estudos sugerem que o spray tem um custo menor. A escolha do método de administração do aerossol depende de considerações sobre o custo. O objetivo deste estudo é comparar os custos entre nebulização intermitente com fluxo de ar comprimido versus spray acoplado a espaçador valvulado na administração do aerossol broncodilatador no tratamento da asma aguda no setor de adultos da sala de emergência. Métodos: Comparamos os custos de diferentes agentes beta-adrenérgicos, com e sem brometo de ipratrópio, administrados por nebulização intermitente versus spray acoplado a espaçador valvulado no setor de adultos da emergência do Hospital de Clínicas de Porto Alegre. As comparações foram feitas para 1, 6 e 12 horas de tratamento. Foram considerados os custos de todos os materiais utilizados. Resultados: O spray com espaçador consistiu em um método mais barato de administrar o broncodilatador em comparação com a nebulização intermitente para diferentes agentes beta-agonistas, com e sem ipratrópio Conclusões: A administração do broncodilatador por spray com espaçador valvulado foi mais econômica em comparação à administração por nebulização intermitente no tratamento da asma aguda na sala de emergência. O tratamento com spray/espaçador é progressivamente mais barato à medida que o tempo de permanência no setor de emergência aumenta. Unitermos: Estudo de custo; medicina de emergência; tratamento da asma aguda; espaçador; nebulizador.Objetive: Bronchodilator delivery by means of metered-dose inhaler or intermittent nebulization is equivalent in the acute treatment of asthma. Some studies suggest that metereddose inhaler is less costly. The choice of the delivery method will depend on the consideration of costs. The aim of the present study is to compare the costs of aerosol bronchodilator delivery by use of an intermittent nebulizater versus metered-dose inhaler with valved spacer in patients with acute asthma in the adult emergency department. Methods: We compared the costs of different beta-adrenergic agents with and without ipratropium bromide delivered by intermittent nebulizer versus metered-dose inhaler with valved spacer in the adult emergency department of Hospital de Clínicas de Porto Alegre. Comparisons were made for 1, 6 and 12-hour treatment. The costs of all material used were taken into consideration. Results: The metered-dose inhaler with spacer was a less costly method of bronchodilator delivery in comparison to intermittent nebulization for the different beta-agonist agents, with and without ipratropium bromide. Conclusions: Bronchodilator delivery by means of a metered-dose inhaler with valved spacer was cost-saving in comparison to delivery by means of an intermittent nebulization in the treatment of acute asthma in the emergency department. The metered-dose inhaler/spacer treatment is progressively less expensive as the length of stay in the emergency department increases
