Abstract
in English, Portuguese

Objective: To evaluate the applicability of the London Chest Activity of Daily Living (LCADL) scale in patients on the waiting list for lung transplantation.

Methods: This was a cross-sectional study, conducted between May and September of 2010, involving 26 male and female patients on the waiting list for lung transplantation and treated at the Pulmonary Rehabilitation Program in the Complexo Hospitalar Santa Casa de Misericórdia de Porto Alegre, located in the city of Porto Alegre, Brazil. We evaluated the patients using the six-minute walk test (6MWT) and pulmonary function tests. We also obtained the LCADL scores, as well as the modified Borg scale scores for sensation of dyspnea and leg fatigue. Cronbach's alpha coefficient was used to determine the internal consistency of the LCADL scale. Linear regression analysis was used in order to identify associations between the total LCADL score (expressed as a percentage) and the variables studied.

Results: According to the LCADL scale results, 69% of the patients reported that the performance of their activities of daily living was significantly impaired by their dyspnea. The internal consistency of the LCADL scale was 0.89. After adjusting for age and FEV1, we found that the total LCADL scale score showed statistically significant negative associations with the six-minute walk distance (β = -0.087; p < 0.001) and the six-minute walk work (β = -0.285; p < 0.001).

Conclusions: Our findings suggest that the LCADL scale is a useful tool for assessing patients on the waiting list for lung transplantation.

OBJETIVO:: Avaliar a aplicabilidade da escala London Chest Activity of Daily Living (LCADL), em pacientes em lista de transplante pulmonar.

MÉTODOS:: Estudo transversal com 26 pacientes em lista de espera para transplante de pulmão, de ambos os sexos, entre maio e setembro de 2010 tratados no Programa de Reabilitação Pulmonar, Complexo Hospitalar Santa Casa de Misericórdia de Porto Alegre, em Porto Alegre, RS. Todos os pacientes foram submetidos ao teste de caminhada de seis minutos (TC6) e a teste de função pulmonar e foram obtidos os escores das escalas LCADL e de Borg modificada para dispneia e fadiga das pernas. O teste alfa de Cronbach foi utilizado para verificar a consistência interna da escala LCADL. A análise de regressão linear foi utilizada para identificar associações entre o escore total em porcentagem da escala LCADL e as variáveis estudadas.

RESULTADOS:: Segundo os resultados da LCADL, 69% dos pacientes indicaram que suas atividades de vida diária são muito comprometidas pela dispnéia. A consistência interna da escala LCADL foi de 0,89. Houve associações negativas estatisticamente significativas entre o escore total da escala LCADL e distância percorrida no TC6 (β = −0,087; p < 0,001) e trabalho realizado no TC6 (β = −0,285; p < 0,001), quando os dados foram ajustados por idade e VEF1.

CONCLUSÕES:: Esses achados sugerem que a escala LCADL é um instrumento útil para avaliar o desempenho funcional dos pacientes em listas de transplante pulmonar.
