The awareness of chest physicians about nutritional assessment in chronic obstructive pulmonary disease

The number of studies that target nonpharmacologic treatments for chronic obstructive pulmonary disease (COPD) are increasing because no existing pharmacologic treatment modality for COPD leads to significant improvement in lung function.Positive effects can be observed in patients with COPD using nutritional support alone or as an adjunct to exercise. In this study, we aimed to evaluate the awareness of chest physicians about the nutritional state of patients with COPD.

A questionnaire consisting of 15 multiple choice questions was conducted to 121 chest physicians. The questions were formed to evaluate the awareness of chest physicians on the patients' nutritional state and the importance of nutrition in COPD follow-up.

In total, of the 121 physicians, only 3 (2.5%) reported undertaking routine assessment for nutritional state of patients with COPD. The rates of physicians who routinely questioned patients about weight loss and loss of appetite were 56.2% (n= 68) and 51.2% (n= 62), respectively. Forty-five (37.2%) physicians said that they usually started nutritional support if they detected weight loss in patients with COPD.

Although there is limited data on the benefits of nutritional supplementation for patients with COPD, some studies have suggested advantages of nutritional support against the progress of COPD. Our study showed that routine screening for malnutrition in patients with COPD is rare among chest physicians and this did not differ according to the hospitals in which they worked or from where they took their residency training. There is a need for further studies emphasizing the importance of nutritional state in the progress of COPD.
