Relación entre el volumen espiratorio máximo en un segundo, el índice BODE y la calidad de vida percibida por el paciente de enfermedad pulmonar obstructiva crónica

Abstract

Objective

To measure the correlation between perceived quality of life and two objective severity parameters: forced expiratory volume in one second (FEV₁) and body mass, airflow obstruction, dyspnea and exercise capacity (BODE) index.

Material and methods

Observational descriptive cross-sectional study involving 40 Chronic Obstruction Pulmonary Disease (COPD) patients. They were classified using the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification system into moderate or severe. The Saint George Respiratory Questionnaire (SGRQ) was carried out by interview and the BODE value was analyzed after measurement of the parameters included in it. Anthropometry and demography data were also collected.

Results

A study including 40 patients, 38 of them men 38 (95%), with mean age 76.15 ± 5.82 was performed. The means obtained for the subjective variable of the SGRQ was 33.58 ± 18.14. Regarding the data obtained for the objective variables, the FEV₁ had a mean of 49.05 ± 15.731, and the BODE index showed 2.33 ± 1.8. The parameters making it up were: 6-minute exercise test 440 ± 87.9, mean MRC score: 1.4 ± 0.6, and body mass index (BMI) 28.16 ± 4.4. According to the values obtained, we observed the existence of a correlation between SGRO and the BODE index and between the activity, and subscale of the SGRO and BODE index.

Conclusions

The BODE index are weakly correlative with the results of the SGRO combined. High index BODE negatively affects the perceived quality of life of moderate/severe COPD patients.
