Abstract
SESSION TITLE: Phenotyping and Management of COPD SESSION TYPE: Original Investigations PRESENTED ON: October 18-21, 2020 PURPOSE: Patients with Chronic Obstructive Pulmonary Disease (COPD) who experience exacerbations present a resource burden on the healthcare system. There is little information on healthcare resource utilization (HRU) across commercial and government payers, providing an opportunity for greater understanding of needs. This study describes COPD-related HRU after first diagnosis in claims data by exacerbation frequency and payer type. METHODS: This retrospective study used Medicare Fee-for-Service (FFS) claims and the Inovalon MORE2 Registry® of commercial (COM), Managed Medicaid (MM), and Medicare Advantage (MA) claims. Patients were aged ≥40 years with continuous enrollment 1 year pre- and post-index. Index date was first emergency department (ED) visit or hospitalization, or first of two outpatient medical visits ≥ 30 days apart between 1/1/2015-9/30/2018 (MORE2) or 1/1/2015-12/31/2017 (FFS) with a COPD diagnosis code. Exclusion criteria were pre-index diagnosis of COPD or use of COPD-related medications, or diagnoses of asthma, cancer, interstitial fibrosis, pulmonary embolism, pulmonary hypertension, or sarcoidosis. Post-index exacerbation events were categorized (0, 1, or 2+) and defined by primary COPD-related diagnosis during inpatient or a COPD-related outpatient/ED visit with a prescription for an antibiotic or oral corticosteroid within 5 days. RESULTS: Among 1,406,727 COPD patients, mean (SD) age was 69.9 (11.6) years, 59.2% were female, and payer distribution was 3.9% MA, 4.5% COM, 7.5% MM, and 84.1% FFS. Post-index, 34.7% experienced ≥1 exacerbation (1=28.8%, 2+=5.9%). The proportion of patients with 2+ exacerbations was consistent across payers: 5.2% MA, 5.5% COM, 5.9% FFS, and 6.0% MM. Overall, 11.6% of patients had ≥1 COPD-related hospitalization and of those 25.3% had a COPD-related 30-day readmission. COPD-related hospitalizations ranged from 9.7% for COM to 18.0% for MA, and 30-day readmission rates from 16.6% for COM to 26.5% for FFS. As the number of exacerbations increased, there were corresponding increases in patients with ≥1 COPD-related ED visits (0=11.5%, 1=23.2%, 2+=34.9%), ≥1 hospitalizations (1=9.2%, 2+=23.7%), and ≥1 30-day readmissions (1=20.5%, 2+=34.4%). For those with 2+ exacerbations, COPD-related ED visit frequency ranged from 34.3% for FFS to 46.0% for MA, and 30-day readmissions from 17.2% for COM to 36.6% for FFS. CONCLUSIONS: Patients experiencing 1 or more exacerbations in the year following COPD diagnosis have high HRU related to hospitalizations, readmissions, and ED visits. The pattern of increasing HRU with greater exacerbation frequency was consistent across payers. CLINICAL IMPLICATIONS: These results highlight a need to evaluate COPD patients early in their disease course for appropriate treatment with the aim of reducing exacerbations, which are directly linked to hospitalizations and readmissions.
