Objectives: While patient input to health technology assessment (HTA) has traditionally been of a qualitative nature, there is increasing interest to integrate quantitative evidence from patient preference studies into HTA decision making. Preference data can be used to generate disease-specific health utility data. We generated a health utility score for patients with chronic obstructive pulmonary disease (COPD) and consider its use within HTAs.

The aim of this phase IIb dose-finding study was to compare a CFTR potentiator, icenticaftor (QBW251), with placebo in patients with COPD and chronic bronchitis. Patients with COPD on triple therapy for at least three months were randomized to six treatment arms (icenticaftor 450, 300, 150, 75, or 25 mg or placebo twice daily [b.

In nematodes, neuronal degeneration can be reversed by intestinal GABA and lactate-producing bacteria, or by hibernation driven by food deprivation. However, it is not known whether these neuroprotective interventions share common pathways to drive regenerative outcomes.

The Cough and Sputum Assessment Questionnaire (CASA-Q) was developed and tested for this purpose. This study reviewed the performance of the CASA-Q in published online studies and tested a novel approach to complement traditional methods of qualitative content validation.

Despite the essential functions conferred by microbes, the source and acquisition of the rhizosphere are not entirely clear. Therefore, we investigated microbial community diversity and potential source using the only two native Antarctic plants, (Da) and (Cq), as models.

Over the years, terminology and methods for developing recommendations for PRO score interpretation in clinical trials have evolved, leading to some confusion in the field. The phrase "minimal clinically important difference (MCID)" has been simplified to "minimal important difference (MID)" and use of responder thresholds to interpret statistically significant treatment effects has increased.

Methods: The inclusion criteria were people living with COPD aged 40 years or older who experienced ≥1 exacerbation in the previous year with daily symptoms of cough and excess mucus production. The study design included: 1) development of an attributes and levels grid through qualitative patient interviews; and 2) implementation of the main online quantitative survey, which included a discrete choice experiment (DCE) to allow assessment of attributes and levels using hypothetical health state profiles.
Rationale: Patients with chronic obstructive pulmonary disease (COPD) struggle with respiratory symptoms that impair their daily activities and quality of life. Understanding a treatment's ability to relieve symptoms requires precise assessment. The Evaluating Respiratory Symptoms in COPD (E-RS:COPD) was developed to quantify respiratory symptoms in clinical trials.

Passive observation of such online interaction between patients (social media listening) is conducted in order to understand the burden of the disease, symptom perception, and expectations from a patient perspective. For most conditions, it remains to be established how representative the social media user community is for the overall patient population.

However, the clinical trials evaluating these and other novel treatments have used a variety of different outcomes to evaluate efficacy. The evolution of asthma care calls for a re-examination of outcomes that are most important to patients and other stakeholders.
View Article and Find Full Text PDFPurpose: The aim of this study was to assess the association between exacerbation frequency and clinical and economic outcomes in patients with COPD.
Patients And Methods: Electronic medical record data linked to National Health Registries were collected from COPD patients at 52 Swedish primary care centers (2000-2014). The outcomes analyzed were exacerbation rate, mortality, COPD treatments, lung function and healthcare costs during the follow-up period.

This study reports the association of ICS use and the risk of type 2 diabetes mellitus (T2DM) in Swedish patients with COPD using data from real-world, primary care settings. A total of 7078 patients with COPD were included in this analysis and the 5-year cumulative incidence rate per 100,000 person years was 1506.9.

Materials And Methods: RMT analysis was conducted on the baseline SGRQ data from five multi-national, Phase III randomized trials investigating a fixed-dose combination of a long-acting β2-agonist and a long-acting muscarinic antagonist in COPD patients.
The effect of inhaled corticosteroids (ICS) on the risk of osteoporosis and fracture in patients with chronic obstructive pulmonary disease (COPD) remains uncertain. The aim of this study was to assess this risk in patients with COPD.Electronic medical record data linked to National Health Registries were collected from COPD patients and matched reference controls at 52 Swedish primary care centres from 2000 to 2014.

Dauer entry as a response to chronic exposure to pathogenic bacteria in is an example of a dramatic survival response. This response is dependent on the RNA interference (RNAi) machinery, suggesting the involvement of small RNAs (sRNAs) as effectors.

Key characteristics of chronic obstructive pulmonary disease (COPD) that significantly affect health-related quality of life (HRQoL) include chest symptoms, dyspnea, cough, sputum production, and exacerbations. Additional areas of impact are sleep, fatigue, emotional well-being, social functioning, and coping. Patient-reported outcomes (PROs) are essential to evaluate symptoms, impact of symptoms on activities of daily living, and treatment response.
View Article and Find Full Text PDFPurpose: Previous studies have shown that opportunities to diagnose chronic obstructive pulmonary disease (COPD) early are often missed in primary care. This retrospective study aimed to utilize secondary data from the United Kingdom (UK) healthcare system to understand the impact of early versus late diagnosis of COPD.
Patients And Methods: Newly diagnosed COPD patients were identified in the UK Clinical Practice Research Database from 2011 to 2014.
Purpose: Exacerbations drive outcomes and costs in chronic obstructive pulmonary disease (COPD). While patient-level (micro) simulation cost-effectiveness models have been developed that include exacerbations, such models are complex. We developed a novel, exacerbation-based model to assess the cost-effectiveness of indacaterol/glycopyrronium (IND/GLY) versus salmeterol/fluticasone (SFC) in COPD, using a Markov structure as a simplification of a previously validated microsimulation model.

Applying a decision tree model, we assumed a hypothetical absence of OS and compared OS (intervention) with conservative treatment (CONS; comparator). We included patients with femur, tibia and radius fractures (age <65 years) and for proximal femur fractures also elderly patients (≥70 years).

ARCTIC is a large, real-world, retrospective cohort study conducted in Swedish COPD patients and a matched reference population from 52 primary care centers in 2000-2014. The incidence of COPD, prevalence of asthma and other comorbidities, risk of exacerbations, mortality rate, COPD drug prescriptions, and healthcare resource utilization were analyzed.

The four-step approach comprised the following: literature search, social media listening (SML) study, online bulletin board (OBB) exercise, and design of an online patient preference study (PPS). The initial online studies (SML and OBB) revealed that, besides dyspnoea and exacerbations, patients perceive cough and mucus production as equally important aspects of disease management for COPD.

Aim of this study was to evaluate AO's impact on science, education, patient care and the MedTech business.
Design/methods: Impact evaluations were conducted as appropriate for the individual domains: Impact on science was measured by analyzing citation frequencies of publications promoted by AO.

Qualitative research provides real-life information on patients' condition and facilitates informed design of future clinical studies. We used Online Communities as a qualitative research tool to evaluate the effect of cough and mucus on COPD patients. Two 2-week Online Communities were run in parallel in the UK and in the USA, including COPD patients with persistent cough and excessive mucus.
