Quantifying the Economic Impact of Delayed Multiple-Inhaler Triple Therapy Initiation in Patients with COPD: A Retrospective Cohort Study of Linked Electronic Medical Record and Hospital Administrative Data in England

Purpose

To assess if early multiple-inhaler triple therapy (MITT) initiation in patients with chronic obstructive pulmonary disease (COPD) reduces subsequent healthcare resource utilization (HCRU), direct medical costs, and acute exacerbations of COPD (AECOPDs).

Patients and Methods

This retrospective, longitudinal cohort study used electronic health records and linked hospital administrative data in England. COPD patients with an AECOPD between July 2012 and May 2016 (index), and who subsequently started MITT within 180 days were eligible. Patients with an AECOPD 6 months prior to index were excluded. HCRU, direct healthcare costs, and AECOPDs were assessed in the following 24-month period for early (≤30 days) and delayed (31-180 days) MITT initiators.

Results

A total of 934 patients were included in the analysis and categorized as early (n=367, 39%) or delayed (n=567, 61%) MITT initiators. Mean patient age was 68.5 years and 53.2% were male. A significantly higher proportion of delayed MITT initiators required ≥1 outpatient appointment (all-cause) compared with early MITT initiators (87% vs 79%; p=0.0016). A significantly higher proportion of delayed MITT initiators required ≥1 COPD‑related inpatient stay versus early MITT initiators (47% vs 40%; p=0.0262). Over the 24-month follow-up, mean all-cause and COPD-related total healthcare costs were significantly higher in delayed MITT initiators compared with early MITT initiators (all‑cause: £11,348 vs £8126; p=0.0011; COPD-related: £7307 vs £4535; p=0.0009).

Conclusion

Delayed initiation of multiple-inhaler triple therapy was associated with higher all-cause and COPD-related costs, suggesting that earlier initiation of triple therapy in COPD patients may help reduce the economic burden on the healthcare system.

COPD patients' characteristics, usual care, and adherence to guidelines: the Greek UNLOCK study

Purpose

GOLD guidelines classify COPD patients into A–D groups based on health status as assessed by COPD Assessment Test (CAT) or mMRC tools and exacerbations and recommend single or dual long-acting bronchodilators as maintenance therapy, with additional inhaled corticosteroids (ICS) if the disease remains uncontrolled. We aimed to classify primary care COPD patients into A–D groups, assess usual treatment and adherence to guidelines, potential mismatches between CAT-and mMRC-based classification and described symptoms within groups.

Patients and methods

A total of 257 primary care COPD patients were enrolled between 2015 and 2016 in Greece. Physicians used structured interviews to collect cross-sectional data including demographics, symptoms, CAT, mMRC scores, and medications. Patients were classified into A–D groups based on CAT and mMRC, and prevalence of symptoms and medication was estimated within A–D groups. Interviews with physicians were also performed to explore additional issues about treatment and adherence to guidelines.

Results

Mean (SD) age was 65 (12.3) years with 79% males. The majority of patients reported uncontrolled symptoms (91% and 61% with ≥10 CAT or ≥2 mMRC scores, respectively). Thirty-seven percentage had $2 exacerbations in the past year. Group B was the largest followed by Groups D, A, and C. Patients were classified as more severe by CAT than by mMRC. In all groups, the majority were treated with combined long-acting beta agonist/ICS (> 50%). When patients were asked to report their main symptoms, dyspnea and cough were the most important symptoms mentioned, and there was a great variation between the A–D groups. However, Groups A–C reported mainly morning symptoms, whereas Group D suffered symptoms all day. Physicians reported a significant number of barriers to implementing guidelines, eg, frequent lack of guideline updates, access to diagnostic procedures, and prescription-reimbursement issues.

Conclusion

Our study confirms poor adherence to guidelines regarding treatment with an overuse of ICS and important barriers to implementation. A mismatch in classification occurs depending on the tool used, which can mislead clinicians in their choice of treatment.
