ObjectiveTo evaluate the effect of long-distance medical intervention on chronic obstructive pulmonary disease (COPD) assessment test (CAT) scores of stable COPD patients. MethodsA total of 244 stable COPD patients treated in our hospital between November 2011 and November 2012 were randomly divided into two groups with 122 in each. Group one was treated with long-distance medical intervention and group two with route nursing care. CAT scores were obtained at discharge from hospital and 3 months later. ResultsBaseline CAT scores of the two groups were respectively 23.99±8.03 and 22.14±7.71 with no significant difference between the two groups (P>0.05). Three months later, CAT scores of the two groups were respectively 17.54±7.83 and 20.93±7.21, and the difference was statistically significant (P<0.05). ConclusionThe CAT score of stable COPD patients can be improved by long-distance medical invention.
