Abstract

PURPOSE:Dyspnea is a disabling symptom limiting quality of life in a significant population suffering respiratory and non respiratory diseases. There is a need for cultural sensitive instruments to assess its severity in Puerto Rico, a Latino population.

METHODS:The Oxygen Cost Diagram was developed in English to measure dyspnea with activities of daily living. It was translated to Spanish and adapted to the Puerto Rican culture in a previous qualitative cultural study. To assess its psychometric properties the adapted version was tested in subjects referred to a laboratory for pulmonary function tests. Subjects rated their perception of air hunger in the OCD, performed a pulmonary function test and a six minutes walk.

RESULTS:Ninety three subjects having asthma, COPD, lung fibrosis, lung mass, collagen disease, arterial hypertension and other non respiratory diseases were recruited. Mean age was 52 years old (range 21 to 80), 54% were women, and the educational background varied from less than 6th grade to university education. The mean FEV1 was 78.8% (range 25 to 120%), but in only %5 it was below 50% of predicted. OCD ratings and the measured FEV1% were significantly correlated although the correlation was weak (2 tailed 0.007; spearman’s rho 0.285). The correlation of the OCD to the 6 min walking distance was higher (P < 0.0001, spearman’s rho 0.517).

CONCLUSION:The Spanish version of the OCD adapted for its use in Puerto Rico correlated well with objective measures of capacity of ambulation such as the 6 min walk test. Correlation with FEV1 was weak, but limited by the scarcity representation of the severely impaired pulmonary patients.

CLINICAL IMPLICATIONS:The adapted Spanish OCD may be used to assess the patient’s perception of exercise tolerance in the Puerto Rican population and its rating is significantly correlated to distance walked in six minutes and to FEV1.
