Overview of chronic cough

The estimated global prevalence of chronic cough (CC) is close to 10%; however, this is likely higher, as many epidemiologic surveys do not adequately capture symptoms or diagnoses of CC. There is a large healthcare burden associated with CC as well as decreased quality of life (QOL). CC has previously been considered a symptom of other comorbidities. Now that it is regarded as a disease state on its own, education is needed to ensure a CC diagnosis is not missed and is adequately treated. CC is associated with many complications and triggers. Unfortunately, there are few effective therapies for CC, and many have severe adverse effects that limit use. Many people experience decreased QOL because of the impact of CC on daily activities. Because there is not a standard definition of chronic cough in the literature, a comprehensive approach to taking a cough history is essential. It is important to consider all triggers, including occupational and geographic triggers. Identified gaps in care include appropriate history taking, efficacious treatments, and more clinicians specializing in cough. Pharmacists require education on the background of CC and current and future therapies to improve disease competency, clinical decision making, and interventions to enhance the QOL by treating CC. Improved decision making will allow pharmacists to educate people with CC and provide resources to enhance their cough-related QOL.
