BODE index

The BODE index, for Body-mass index, airflow Obstruction, Dyspnea, and Exercise, is a multidimensional scoring system and capacity index used to test patients who have been diagnosed with chronic obstructive pulmonary disease (COPD) and to predict long-term outcomes for them. The index uses the four factors to predict risk of death from the disease.

The BODE index will result in a score of zero to ten dependent upon FEV₁ or "forced expiratory volume in one second" (the greatest volume of air that can be breathed out in the first second of a breath), body-mass index, the distance walked in six minutes, and the modified MRC dyspnea scale.{{Cite book |last1=Cislo |first1=Geoffrey S. |url=https://books.google.com/books?id=ZptEP_hDrlwC&pg=PA96 |title=General Internal Medicine Consult |last2=Fer |first2=Thomas M.

Results of spirometry are also good predictors of the future progress of the disease, but they are not as good as the test results of the BODE index.{{cite book |first1=John J. |last1=Reilly |first2=Edwin K. |last2=Silverman |first3=Steven D. |last3=Shapiro |chapter=Chronic Obstructive Pulmonary Disease |pages=2151–9 |editor1-first=Dan |editor1-last=Longo |editor2-first=Anthony |editor2-last=Fauci |editor3-first=Dennis |editor3-last=Kasper |editor4-first=Stephen |editor4-last=Hauser |editor5-first=J. |editor5-last=Jameson |editor6-first=Joseph |editor6-last=Loscalzo |year=2011 |title=Harrison's Principles of Internal Medicine |edition=18th |publisher=McGraw Hill |isbn=978-0-07-174889-6}}{{NICE|101|Chronic Obstructive Pulmonary Disease|June 2010|60-70}}
