60. January 2009 Treating COPD and Asthma Mucusdoc@hotmail.com Systemic Corticosteroids Treatment of an exacerbation of COPD with oral or parenteral corticosteroids significantly reduces treatment failure and the need for additional medical treatment . It increases the rate of improvement in lung function and dyspnoea over the first 72 hours, but at a significantly increased risk of an adverse drug reaction
61. January 2009 Treating COPD and Asthma Mucusdoc@hotmail.com Bacterial vs. Non-bacterial Bacterial: potential pathological microorganism isolated in 19% of 116 COPD exacerbations
Non-bacterial: negative result of a sputum Gram stain, absence of a decrease in lung function and occurrence of <2 exacerbations in the previous year …….100% predictive of a nonbacterial origin of the exacerbation.
The presence of all 3 of these clinical characteristics yielded a positive predictive value of 67% for a bacterial exacerbation. Save $$$?
