Real-world care patterns and specialist encounters of patients with systemic autoimmune rheumatic disease-related interstitial lung disease in the United States: a retrospective administrative claims database analysis.

ABSTRACT:

Objectives

We aimed to describe the demographics, clinical characteristics and care patterns of patients with systemic autoimmune rheumatic diseases (SARD) prior to their interstitial lung disease (ILD) diagnosis.

Methods

Adults diagnosed with SARD-ILD were identified, with the earliest ILD diagnosis date designated as the index date. A minimum of 36 months of continuous enrolment before the index date was required. All measures were analysed descriptively. For a subset of patients with respiratory symptoms before ILD diagnosis, the association between type of specialist encounter and time from symptom onset to SARD-ILD diagnosis was assessed using a Cox prop
