Implementation of British Thoracic Society guidelines for acute exacerbation of chronic obstructive pulmonary disease: impact on quality of life.

backgroundThe British Thoracic Society (BTS) guidelines have not been examined collectively for their impact on chronic obstructive pulmonary disease (COPD). Whether intensive outpatient follow up of COPD patients after acute admission, using these guidelines, improved quality of life compared to the "usual practice" of primary care follow up was investigated.

methodsAltogether 103 patients with a new diagnosis of COPD were admitted and screened over a four year period. Seventy patients were excluded because of another dominant medical condition or a mandatory requirement for intervention. Patients were randomised to regular primary care (control group, n = 15) or chest clinic follow up (intervention group, n = 10). Spirometry, oxygen saturation, St George's Respiratory Questionnaire (SGRQ), and Short Form 36 questionnaire were measured at baseline and six months. The intervention group was reviewed at least four times in the six month period and received spirometry, ambulatory oxygen assessment, smoking cessation advice, nebuliser assessment, a steroid trial, advice about nutrition/exercise, and introduction to a patient support group.

resultsThere was no significant difference between baseline measurements in the two groups. There was a significant mean (SD) improvement in the SGRQ symptom score from baseline to six months in the intervention group [20.98 (20.36)] compared with the controls [0.23 (12.55)] (p = 0.004). At six months the SGRQ symptom score, impact score, and total score was significantly better in the intervention than the control group (p = 0.01, 0.02, and 0.02).

conclusionAggressive implementation of BTS guidelines after initial hospitalisation may improve respiratory health specific quality of life scores in patients with COPD. Larger studies are needed to confirm this finding.
