The Director of the Centers for Disease Control recently highlighted a campaign to convince up to 86 million Americans that they have pre-diabetes, a condition that doesn't even exist. Meanwhile, the Obama administration is concerned that health care costs under the Affordable Care Act have skyrocketed and millennials are opting to pay the penalty rather than get the health care, which could be twice as expensive. 

That is one of the reasons why increasing diagnoses and hospitalizations of chronic obstructive pulmonary disease (COPD) are a concern. 

There's no doubt that asthma is real, but its broad use as a term is an outdated approach to understanding an individual's condition, according to a paper in the European Respiratory Journal. In a perspective article, Professor Alvar Agusti and colleagues call for a new approach to patient management, which moves away from categorizing patients using the broad disease terms of asthma and COPD and towards a more personalized approach to management that identifies 'treatable traits' in each patient. 

Hospitalization rates for COPD are continuing to increase and a majority of asthma patients live with significant symptoms, impairing their quality of life. While the labels of asthma and COPD are valuable for patients who display stereotypical symptoms, there are a growing number of patients who do not fit this category, including patients with adult-onset asthma, smoking asthmatics, or patients with the so-called asthma-COPD overlap syndrome. 

In the past 30 years, new technologies have developed, providing clinicians with a range of tools to allow them to observe a patient and define that patient's condition. Previously, understanding a patient's condition relied on analysis of symptoms and signs, such as lung function measurements and airway hyper-responsiveness, but now clinicians can access information about a range of other underlying complex biological traits, including cellular and molecular traits. This could include measures such as CT scanning, cellular and molecular markers taken from blood samples, sputum and exhaled air and microbiome analysis. 

Professor Agusti commented, "We propose a label-free precision medicine approach based on treatable traits that categorize the clinical and biological complexity of airway disease. The approach we are suggesting would radicalize health care and have significant implications for the organization of a health care system. By recognizing the clinical and biological complexity of a disease, we can use causal mechanistic disease pathways to adopt a more precise approach, which is hopefully more effective at managing patients with these conditions."  

In an accompanying editorial, Professor Peter Sterk, from the University of Amsterdam, supports the call for a move away from diagnostic labels. Professor Sterk commented, "We are living in an era where we have new biological knowledge and new targets for therapy but we largely continue to guide patient management with diagnostic labels. It is the right time for health care professionals to take bold steps and move aware from historical diagnoses that are impeding modern medicine."
