Short-term Evaluation of a Comprehensive Education Program Including Inhaler Training and Disease Management on Chronic Obstructive Pulmonary Disease.

ABSTRACT: BACKGROUND:Proper education regarding inhaler usage and optimal management of chronic obstructive pulmonary disease (COPD) is essential for effectively treating patients with COPD. This study was conducted to evaluate the effects of a comprehensive education program including inhaler training and COPD management. METHODS:We enlisted 127 patients with COPD on an outpatient basis at 43 private clinics in Korea. The patients were educated on inhaler usage and disease management for three visits across 2 weeks. Physicians and patients were administered a COPD assessment test (CAT) and questionnaires about the correct usage of inhalers and management of COPD before commencement of this program and after their third visit. RESULTS:The outcomes of 127 COPD patients were analyzed. CAT scores (19.6±12.5 vs. 15.1±12.3) improved significantly after this program (p<0.05). Patients with improved CAT scores of 4 points or more had a better understanding of COPD management and the correct technique for using inhalers than those who did not have improved CAT scores (p<0.05). CONCLUSION:A comprehensive education program including inhaler training and COPD management at a primary care setting improved CAT scores and led to patients' better understanding of COPD management.

Project description:BACKGROUND:Guidelines recommend that treatment with a long-acting β2 agonist (LABA), a long-acting muscarinic antagonist (LAMA), and inhaled corticosteroids (ICS), i.e. triple therapy, is reserved for a select group of symptomatic patients with chronic obstructive pulmonary disease (COPD) who continue to exacerbate despite treatment with dual therapy (LABA/LAMA). A number of single-inhaler triple therapies are now available and important clinical questions remain over their role in the patient pathway. We compared the efficacy and safety of single-inhaler triple therapy to assess the magnitude of benefit and to identify patients with the best risk-benefit profile for treatment. We also evaluated and compared study designs and population characteristics to assess the strength of the evidence base. METHODS:We conducted a systematic search, from inception to December 2018, of randomised controlled trials (RCTs) of single-inhaler triple therapy in patients with COPD. The primary outcome was the annual rate of moderate and severe exacerbations. RESULTS:We identified 523 records, of which 15 reports/abstracts from six RCTs were included. Triple therapy resulted in the reduction of the annual rate of moderate or severe exacerbations in the range of 15-52% compared with LAMA/LABA, 15-35% compared to LABA/ICS and 20% compared to LAMA. The patient-based number needed to treat for the moderate or severe exacerbation outcome ranged between approximately 25-50 (preventing one patient from having an event) and the event-based number needed to treat of around 3-11 (preventing one event). The absolute benefit appeared to be greater in patients with higher eosinophil counts or historical frequency of exacerbations and ex-smokers. In the largest study, there was a significantly higher incidence of pneumonia in the triple therapy arm. There were important differences in study designs and populations impacting the interpretation of the results and indicating there would be significant heterogeneity in cross-trial comparisons. CONCLUSION:The decision to prescribe triple therapy should consider patient phenotype, magnitude of benefit and increased risk of adverse events. Future research on specific patient phenotype thresholds that can support treatment and funding decisions is now required from well-designed, robust, clinical trials.

Project description:Two studies were undertaken to characterize the maximal effort inhalation profiles of healthy subjects and patients with asthma or chronic obstructive pulmonary disease (COPD) through a moderate-resistance dry powder inhaler (DPI). Correlations between inhaler-specific inhalation characteristics and inhaler-independent lung function parameters were investigated.Healthy subjects (n?=?15), patients with mild, moderate, or severe asthma (n?=?45), and patients with mild, moderate, severe, or very-severe COPD (n?=?60) were included in the studies. Inhalation pressure drop versus time profiles were recorded using an instrumented ELLIPTA® DPI or bespoke resistor component with equivalent resistivity. Inhaler-independent lung function assessments included pharyngometry, spirometry, plethysmography, and diffusion.For the inhaler-specific inhalation profiles, the mean maximal effort peak inspiratory flow rates (PIFRs) varied across the subgroups from 65.8-110.6 L/min (range: 41.6-142.9). Peak pressure drop, PIFR, inhaled volume, and average inhalation flow rate (primary endpoints) did not differ markedly between healthy subjects and patients with asthma or mild COPD. Moderate, severe, and very-severe COPD patients demonstrated lower mean peak pressure drops, PIFRs and inhaled volumes, which tended to decrease with increasing COPD severity. Severe and very-severe COPD patients demonstrated shorter mean inhalation times compared with all other participants. Inhaler-independent lung function parameters were consistent with disease severity, and statistically significant (p?<?0.05) strong correlations (R?>?0.7) with components of the inhaler-specific inhalation profiles were observed in the COPD cohort; correlations in the asthma cohort tended to be weaker.All participants achieved a maximal effort PIFR???41.6?L/min through the moderate resistance of the ELLIPTA inhaler. Patients with asthma achieved similar inhalation profiles to healthy subjects, but increasing COPD severity tended to reduce a patient's inhalation capability. Correlation analyses suggest that some lung function parameters may be a useful indicator of ability to inhale efficiently through a moderate-resistance DPI, such as the ELLIPTA inhaler.

Project description:BackgroundInhalers are the mainstay of treatment for patients suffering from chronic obstructive pulmonary disease. However, incorrect inhaler technique is a considerable challenge.ObjectiveWe aimed to evaluate inhaler technique and its association with quality of life in a sample of patients with chronic obstructive pulmonary disease.MethodsThis cross-sectional study included patients with confirmed chronic obstructive pulmonary disease who were prescribed at least 1 inhaler medication on a regular basis. Patients were recruited from the outpatient pulmonary clinic of a hospital in Tehran. Inhaler technique was assessed according to a validated checklist. Patients' quality of life was evaluated using Chronic Obstructive Pulmonary Disease Assessment Test.ResultsOne hundred seventy-five patients with mean (SD) age of 59.0 (10.1) years were included. Patients' devices were 192 (62.3%) pressurized metered-dose inhalers (including pressurized metered-dose inhalers plus spacer) and 116 (37.7%) dry powder inhalers. Unfortunately, only 2.86% of patients used their inhalers completely correct. The highest rate of errors was committed by patients who used metered-dose inhalers plus spacer. Patients with a higher educational degree had significantly lower rate of errors on average (P = 0.001). The most frequent errors made by patients using pressurized metered-dose inhalers or Turbuhaler was priming the inhaler before the first administration in 90.6% and 78.3% of patients, respectively. Chronic Obstructive Pulmonary Disease Assessment Test scores in patients using different inhaler devices were not significantly different. However, in patients with lower quality of life, significantly more patients had poor inhaler technique (P = 0.0001).ConclusionsThere is still considerable need for interventions to optimize inhaler technique. We also noted that appropriate inhaler technique is associated with better quality of life. (Curr Ther Res Clin Exp. 2020; 81:XXX-XXX).
