Chronic breathlessness in fibrotic interstitial lung diseases-patient centered assessment and management in outpatient settings.

Abstract

Chronic breathlessness (CB) or dyspnea is prevalent in fibrotic interstitial lung diseases (F-ILD). It is the main driver of a poor health-related quality of life (HRQOL). Timely and accurate assessment and management of CB are paramount in F-ILD care. This is reflected in latest American and European guidelines that recommend early integration of symptom-targeted therapies. Despite calls for improved CB care, evidence indicates that it remains under recognized and under treated. This narrative review focuses on the current evidence for CB assessment and management in F-ILD and proposes an algorithm for patient-centered management of CB in an outpatient setting. An overview of CB assessment tools is provided along with recommendations from guidelines and experts. The limited evidence base for CB interventions in ILD is reviewed; existing dyspnea guidelines recommend a hierarchical approach to therapies starting with the implementation of nonpharmacologic interventions (NPI). Pulmonary rehabilitation is the most common NPI in F-ILD, that improves function, dyspnea, and HRQOL. Oxygen can be prescribed to treat CB associated with exertional hypoxemia early in the course of F-ILD, with evidence suggesting short-term improvements in CB and HRQOL. For patients with severe, persistent CB despite optimization of NPI and oxygen, opioids can be prescribed, initially as short-acting, low-dose oral morphine with prophylactic doses for exertion and as needed for crises. Self-management education and written action plans may help improve patient confidence and control. Development of competency in symptom management and fostering a professional and institutional culture prioritizing CB will advance patient care and should be a priority for F-ILD patients.
