Inhaled treatment of COPD: a Delphi consensus statement

Perception and knowledge of general practitioners on COPD management according to the GOLD23 document and reimbursement criteria for drugs prescription: an e-Delphi study

BACKGROUND

COPD management and therapy have been periodically revised to support a more patient-specific approach. Several concerns remain in primary care, such as the proper choice of initial treatment, medication adherence, and missing values for spirometry investigations. These concerns may be exacerbated by inconsistencies between the GOLD23 report and reimbursement criteria, as per the Italian NOTA99, especially for what concerns the assessment of disease severity and related treatment choice. We therefore examined the perception and knowledge of general practitioners (GPs) on COPD management and treatment.

METHODS

We conducted an exploratory e-Delphi study among 600 GPs. The study examined the COPD-related GP's access to spirometry evaluations in primary care clinics; knowledge on early recognition of COPD and related clinical concerns; perception of the clinical application of the NOTA99; the place in therapy of the triple LABA/LAMA/ICS combination.

RESULTS

Among 466 participating GPs (response rate: 70.3%; mean age 52, SD: 14.2; mean years of experience: 21.3, SD: 15) had a good level of knowledge about the GOLD 2023 document and the reimbursement criteria for COPD medications. Nevertheless, a low (34%) direct access to spirometry was reported, along with absence of consensus on the proper choice of initial treatment (especially of use of LABA/LAMA combination), and the re-evaluation of free-triple therapy LABA/LAMA/ICS through specialist's referral.

CONCLUSIONS

This study captured the domains on which further training for GPs might be implemented to improve the management and treatment of COPD. An extension of this e-Delphi to a larger GPs' panel might further confirm these findings.

Investigating the rationale for COPD maintenance therapy prescription across Europe, findings from a multi-country study

This study aims to understand healthcare professionals' thoughts and motivations about optimal management and treatment of patients with chronic obstructive pulmonary disease (COPD). We conducted a DELPHI survey through an online questionnaire distributed to 220 panellists from six European countries and a discrete choice experiment to describe the relationship between selected clinical criteria and the initial COPD treatment of choice. One hundred twenty-seven panellists (general practitioners [GPs] and pulmonologists) completed the survey. Despite the familiarity and use (89.8%) of the GOLD classification for initial treatment selection, a frequent use of LAMA/LABA/ICS was noted. In fact, panellists agreed that inhaled corticosteroids (ICS) are over-prescribed in the primary care setting. Our study showed that GPs felt less confident than pulmonologists with ICS withdrawal. This mismatch observed between best practice and behaviour indicates the need to increase awareness and efforts to improve the adherence to guidelines in clinical practice.

The future exacerbation and mortality of different inhalation therapies among patients with chronic obstructive pulmonary disease in various GOLD groups: a focus on the GOLD 2017 and GOLD 2023 reports

BACKGROUND

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 report revised the combined assessment, merged the C and D groups into the E group, and revised the initial inhalation therapy recommendation.

OBJECTIVES

This study aimed to analyze the future exacerbation and mortality of different inhalation therapies among patients with chronic obstructive pulmonary disease (COPD) in various groups based on the GOLD 2017 and GOLD 2023 reports.

DESIGN

This is a multicenter and retrospective study.

METHODS

Stable COPD patients from the database setup by 12 hospitals were enrolled. The patients were divided into Groups A, B, C, D, and E according to the GOLD 2017 and GOLD 2023 reports. Then, the patients were classified into long-acting muscarinic antagonist (LAMA), long-acting β2-agonist (LABA) + inhaled corticosteroid (ICS), LABA + LAMA, and LABA + LAMA + ICS subgroups. Data on exacerbation and death during 1 year of follow-up were collected.

RESULTS

A total of 4623 patients were classified into Group A (15.0%), Group B (37.8%), Group C (7.3%), Group D (39.9%), and Group E (47.2%). The exacerbation, frequent exacerbation, and mortality showed no differences between different inhalation therapies in Groups A and C. Patients treated with LABA + LAMA or LABA + LAMA + ICS had a lower incidence of exacerbation and frequent exacerbation than patients treated with LAMA or LABA + ICS in Groups B, D, and E. The exacerbation, frequent exacerbation, and mortality showed no differences between different inhalation therapies after combining Groups A with C.

CONCLUSION

Patients in Group A should be recommended to undergo mono-LAMA, while patients in Groups B and E should be recommended treatment with LABA + LAMA, which is consistent with the GOLD 2023 report. However, it is worth considering merging Groups A and C into a single group and recommending mono-LAMA as the initial inhalation therapy.

The Prescribing Practice for COPD: Relationship to Circadian Rhythm, Disease Severity, and Clinical Phenotype in the STORICO Observational Study

INTRODUCTION

While selected clinical and laboratory findings are taken into account to find the best therapeutic strategies for chronic obstructive pulmonary disease (COPD), it is unknown whether the circadian rhythm of respiratory symptoms, a distinctive feature of COPD, affects the prescription pattern of pharmacological therapy. The main aim of this study was to verify whether the circadian rhythm of symptoms correlates with bronchodilating therapy prescribed to COPD patients as per clinical practice. A secondary objective was to assess the relationship between Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage and circadian rhythm of symptoms and health status.

METHODS

Five hundred sixty-six COPD patients were enrolled in the Italian multicenter STORICO study. Patients underwent a multidimensional assessment, and correlates of prescribed therapy were assessed through a multivariate multilevel model.

RESULTS

As expected, patients in GOLD D stage were more likely to receive triple inhaled therapy than GOLD A-C patients, but the circadian rhythm of symptoms, assessed by the nighttime, morning, and daytime symptoms of the COPD questionnaire, was unrelated to the prescription pattern. The multivariate model showed that emphysematous (EM) patients had a 50% increased risk compared with patients affected by chronic bronchitis (CB) of being prescribed long-acting β2-agonists (LABA)/long-acting muscarinic antagonist (LAMA) fixed-dose combination (FDC) instead of triple therapy [relative risk (RR) _{EM versus CB} 1.50, 95% CI 1.11, 2.03]. Symptoms, mainly in the early morning and daytime, were highly prevalent, even in GOLD B stage (76%).

CONCLUSION

Even if we cannot infer about causality of the symptoms-therapy relationship, based on the structured recording of circadian symptoms clearly shows that symptoms are poorly controlled as the circadian rhythm of symptoms does not correlate with the prescription pattern, and many patients are symptomatic both at daytime and by nighttime. Thus, therapy should be better tailored to the individual needs, with special attention to control nocturnal symptoms.

A modified Delphi consensus study to identify improvement proposals for COPD management amongst clinicians and administrators in Spain

AIMS

To identify the obstacles hindering the appropriate management of chronic obstructive pulmonary disease (COPD) in Spain based on consensus amongst clinicians and administrators.

METHODS

A two-round modified Delphi questionnaire was sent to clinicians (pulmonologists and GPs) and administrators, all experts in COPD. The scientific committee developed the statements and selected the participating experts. Four areas were explored: diagnosis, training, treatment, and clinical management. Panellists' agreement was assessed using a 9-point Likert scale, with scores of 1 to 3 indicating disagreement and 7 to 9, agreement. Consensus was considered to exist when 70% of the participants agreed or disagreed with the statement.

RESULTS

Respective response rates for the first and second round were 68% and 91% for clinicians, and 60% and 100% for administrators. The statements attracting the highest degree of consensus were: "Not enough nursing resources (time, staff, duties) are allocated for performing spirometry" (85.3% clinicians; 75% administrators); "Nurses need specific training in COPD" (84.8% clinicians; 100% administrators); "Rehabilitation programs are necessary for treating patients with COPD" (94.1% clinicians; 91.7% administrators); and "Integrated care processes facilitate the deployment of educational programs on COPD" (79.4% clinicians; 83.3% administrators).

CONCLUSIONS

This document can inform the development and implementation of specific initiatives addressing the existing obstacles in COPD management.

WHAT'S KNOWN

COPD is a prevalent and underdiagnosed disease that causes substantial morbidity and mortality. The National COPD Strategy established objectives and work programmes to apply in Spain. There are barriers impeding the application of interventions contemplated in the COPD strategy.

WHAT'S NEW

Different agents involved in COPD management agree that the main challenges to improve COPD management are resource shortages in primary care nursing and lack of training in the use of COPD clinical guidelines. Clinicians and administrators involved in COPD management support the implementation of urgent measures to tackle the underdiagnosis of COPD, especially in primary care, along with the routine inclusion of respiratory rehabilitation programmes for COPD.

An analysis of the dynamic changes in the self-efficacy and quality of life of elderly patients with chronic obstructive pulmonary disease following community-based rehabilitation

OBJECTIVE

This study aimed to investigate the effects of community-based rehabilitation (CBR) on the self-efficacy and quality of life in elderly patients with chronic obstructive pulmonary disease (COPD).

METHOD

Eighty-one elderly patients with COPD admitted to our hospital were recruited as the study cohort and were randomly divided into a control group (n=41) and a study group (n=40). The control group underwent outpatient rehabilitative treatment, and the study group additionally underwent CBR. The treatment effects of the two groups at 1 month, 3 months, and 6 months of intervention were assessed using their pulmonary function and quality of life scores.

RESULTS

After completion of the CBR, the patients in the study group and the control group were scored using the CSES scale, which did not differ at 1 month of intervention, but the scores were higher in the study group than they were in the control group at 3 and 6 months of intervention (P < 0.05). The patients in the study group also scored higher on the WHOQOL-BREF scale than the control group (P < 0.05).

CONCLUSION

CBR improves the self-efficacy and quality of life in elderly patients with COPD.

EAACI position paper on diet diversity in pregnancy, infancy and childhood: Novel concepts and implications for studies in allergy and asthma

To fully understand the role of diet diversity on allergy outcomes and to set standards for conducting research in this field, the European Academy of Allergy and Clinical Immunology Task Force on Diet and Immunomodulation has systematically explored the association between diet diversity and allergy outcomes. In addition, a detailed narrative review of information on diet quality and diet patterns as they pertain to allergic outcomes is presented. Overall, we recommend that infants of any risk category for allergic disease should have a diverse diet, given no evidence of harm and some potential association of benefit in the prevention of particular allergic outcomes. In order to harmonize methods for future data collection and reporting, the task force members propose relevant definitions and important factors for consideration, when measuring diet diversity in the context of allergy. Consensus was achieved on practice points through the Delphi method. It is hoped that the definitions and considerations described herein will also enable better comparison of future studies and improve mechanistic studies and pathway analysis to understand how diet diversity modulates allergic outcomes.

Guiding Principles for the Recognition, Diagnosis, and Management of Infants with Anaphylaxis: An Expert Panel Consensus

Infant anaphylaxis is an emerging risk, with food allergy the most common cause. Although the presentation of anaphylaxis involves the same systems as in older children and adults, there are real-world challenges to identifying symptoms of an allergic emergency in nonverbal children, as well as implementing optimal treatment. Recognition of anaphylaxis in infants can be challenging because allergic symptoms and certain normal infant behaviors may overlap. Intramuscular epinephrine is the treatment of choice for infants, as it is for older children and adults, and an epinephrine autoinjector approved by the Food and Drug Administration is now available for infants weighing between 7.5 and 15 kg. A panel of experts sought to develop guiding principles for the recognition, diagnosis, and management of anaphylaxis in infants, and provide a framework for the development of new guidelines and future research. Accordingly, anaphylaxis emergency action planning for infants was addressed by the panel. In considering formation of future infant anaphylaxis guidelines, health care providers should be aware of the needs to improve the recognition, diagnosis, and management of infants with anaphylaxis. Future research should identify and validate clinical criteria for the diagnosis of anaphylaxis in infants, as well as risk factors for the most severe reactions.

Early management of COPD: where are we now and where do we go from here? A Delphi consensus project

PURPOSE

There is a lack of consensus on the most appropriate early diagnostic strategy, criteria for early access to treatment and follow-up approach for patients with COPD.

MATERIALS AND METHODS

A Delphi consensus project investigated the early management of COPD. We formulated two questionnaires for completion by pneumologists in Italy.

RESULTS

A total of 207 specialists completed questionnaire 1 and 184 of them questionnaire 2, between November 2016 and October 2017. Early diagnosis of COPD was considered uncommon for 93.2% of the expert panel. Regardless of the definition of "early diagnosis" - a diagnosis made before the clinical manifestation of the disease for most responders (60.4%) - experts were confident of the positive effects of early disease management, which they consider is effective in modifying the natural history of the disease. Lack of awareness of the disease was considered the first limiting factor to early COPD management for 78% of respondents. The most effective steps to reduce functional decline were considered to be smoking cessation, followed by long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA), LAMA, LABA, and finally inhaled corticosteroid/LABA (P<0.01 for each paired comparison). Specialists considered it "inappropriate" for general practitioners to perform both the early diagnosis and therapy of COPD without the involvement of a specialist.

CONCLUSION

Early management of COPD is uncommon, and although data on the effects of early disease management on long-term outcomes are limited, Italian experts are confident of the clinical efficacy of this approach.
