Evaluating Quality of Care for Patients with Asthma in the Readmission Penalty Era

Rationale: Asthma poses a significant burden for U.S. patients and health systems, yet inpatient care quality is understudied. National chronic obstructive lung disease (COPD) readmission policies may affect inpatient asthma care through hospital responses to these policies because of imprecise diagnosis and identification of patients with COPD and asthma. Objectives: Evaluate inpatient care quality for patients hospitalized with asthma and potential collateral effects of the Medicare COPD Hospital Readmissions Reduction Program (HRRP). Methods: This was a retrospective cohort study of patients aged 18-54 years hospitalized for asthma across 924 U.S. hospitals (Premier Healthcare Database). Results: Care quality for patients with asthma was evaluated before HRRP implementation (n = 20,820; January 2010-September 2014) and after HRRP implementation (n = 26,885; October 2014-December 2018) using adherence to inpatient care guidelines (recommended, nonrecommended, and "ideal care" [all recommended with no nonrecommended care]). Between 2010 and 2018, at least 80% of patients received recommended care annually. Recommended care decreased similarly (rate of 0.02%/mo) after versus before HRRP (P = 0.8). Nonrecommended care decreased more rapidly after HRRP (rate of 0.29%/mo) versus before HRRP (rate of 0.17%/mo; P < 0.001), with changes driven largely by decreased antibiotic prescribing. Ideal care increased more rapidly after HRRP (rate of 0.25%/mo) versus before HRRP (rate of 0.17%/mo; P = 0.02), with changes driven largely by nonrecommended care improvements. Conclusions: Post-HRRP trends suggest asthma care improved with increased rates of guideline concordance in nonrecommended and ideal care. Although federal policies (e.g., HRRP) may have had positive collateral effects, such as with asthma care, parallel care efforts, including antibiotic stewardship, likely contributed to these improvements.

Role of anticholinergics in asthma management: recent evidence and future needs

PURPOSE OF REVIEW

Anticholinergic antimuscarinic bronchodilators play a major role in the treatment of chronic obstructive pulmonary disease, but their role in asthma has long been limited to acute management. More recently, the role of long-acting antimuscarinic bronchodilators (LAMAs) in chronic asthma management has been explored. This review will examine the pharmacological rationale for use of inhaled anticholinergics in the treatment of asthma, and provide an overview of the current literature supporting this use, as well as describe future research needs in this area.

RECENT FINDINGS

Short-acting anticholinergic bronchodilators have a role as add-on agents in the treatment of acute asthma. Preliminary clinical studies suggest that inhaled LAMAs may be comparable to long-acting beta2-agonists (LABAs) as an add-on therapy in patients not controlled by inhaled corticosteroids (ICS) alone, and may also have added benefit in patients not controlled on combined ICS-LABA. Mechanistic studies suggest that apart from their bronchodilator activity, LAMAs may have anti-inflammatory and antiremodeling influences on the airways. Further research is needed to clarify the clinical relevance of these experimental observations.

SUMMARY

Accumulating evidence supports the use of inhaled LAMAs as an add-on therapy in patients with asthma, who remain symptomatic despite guideline-based therapy with ICS with or without LABAs. Further studies are warranted to help define mechanisms of action of LAMAs, apart from their role as bronchodilators, and determine how these other actions impact asthma outcomes over time. Furthermore, future studies need to examine the long-term efficacy and safety of LAMAs in asthma and identify a subgroup of patients who would benefit from such therapies to facilitate early, personalized therapy.
