Cost-effectiveness and budget impact of the fixed-dose dual bronchodilator combination tiotropium–olodaterol for patients with COPD in the Netherlands

PURPOSE: The fixed-dose dual bronchodilator combination (FDC) of tiotropium and olodaterol showed increased effectiveness regarding lung function and health-related quality of life in patients with chronic obstructive pulmonary disease (COPD) compared with the use of its mono-components. Yet, while effectiveness and safety have been shown, the health economic implication of this treatment is still unknown. The aim of this study was to assess the cost-utility and budget impact of tiotropium-olodaterol FDC in patients with moderate to very severe COPD in the Netherlands. PATIENTS AND METHODS: A cost-utility study was performed, using an individual-level Markov model. To populate the model, individual patient-level data (age, height, sex, COPD duration, baseline forced expiratory volume in 1 second) were obtained from the tiotropium-olodaterol TOnado trial. In the model, forced expiratory volume in 1 second and patient-level data were extrapolated to utility and survival, and treatment with tiotropium-olodaterol FDC was compared with tiotropium. Cost-utility analysis was performed from the Dutch health care payer's perspective using a 15-year time horizon in the base-case analysis. The standard Dutch discount rates were applied (costs: 4.0%; effects: 1.5%). Both univariate and probabilistic sensitivity analyses were performed. Budget impact was annually assessed over a 5-year time horizon, taking into account different levels of medication adherence. RESULTS: As a result of cost increases, combined with quality-adjusted life-year (QALY) gains, results showed that tiotropium-olodaterol FDC had an incremental cost-effectiveness ratio of €7,004/QALY. Without discounting, the incremental cost-effectiveness ratio was €5,981/QALY. Results were robust in univariate and probabilistic sensitivity analyses. Budget impact was estimated at €4.3 million over 5 years assuming 100% medication adherence. Scenarios with 40%, 60%, and 80% adherence resulted in lower 5-year incremental cost increases of €1.7, €2.6, and €3.4 million, respectively. CONCLUSION: Tiotropium-olodaterol FDC can be considered a cost-effective treatment under current Dutch cost-effectiveness thresholds

Development of an allergy management support system in primary care

BACKGROUND: Management of allergic patients in the population is becoming more difficult because of increases in both complexity and prevalence. Although general practitioners (GPs) are expected to play an important role in the care of allergic patients, they often feel ill-equipped for this task. Therefore, the aim of this study was to develop an allergy management support system (AMSS) for primary care. METHODS: Through literature review, interviewing and testing in secondary and primary care patients, an allergy history questionnaire was constructed by allergists, dermatologists, GPs and researchers based on primary care and specialists’ allergy guidelines and their clinical knowledge. Patterns of AMSS questionnaire responses and specific immunoglobulin E (sIgE)-test outcomes were used to identify diagnostic categories and develop corresponding management recommendations. Validity of the AMSS was investigated by comparing specialist (gold standard) and AMSS diagnostic categories. RESULTS: The two-page patient-completed AMSS questionnaire consists of 12 (mainly) multiple choice questions on symptoms, triggers, severity and medication. Based on the AMSS questionnaires and sIgE-test outcome of 118 patients, approximately 150 diagnostic categories of allergic rhinitis, asthma, atopic dermatitis, anaphylaxis, food allergy, hymenoptera allergy and other allergies were identified, and the corresponding management recommendations were formulated. The agreement between the allergy specialists’ assessments and the AMSS was 69.2% (CI 67.2–71.2). CONCLUSION: Using a systematic approach, it was possible to develop an AMSS that allows for the formulation of diagnostic and management recommendations for GPs managing allergic patients. The AMSS thus holds promise for the improvement of the quality of primary care for this increasing group of patients

Assessing the Needs and Perspectives of Patients With Asthma and Chronic Obstructive Pulmonary Disease on Patient Web Portals: Focus Group Study

BACKGROUND: As accessibility to the internet has increased in society, many health care organizations have developed patient Web portals (PWPs), which can provide a range of self-management options to improve patient access. However, the available evidence suggests that they are used inefficiently and do not benefit patients with low health literacy. Asthma and chronic obstructive pulmonary disease (COPD) are common chronic diseases that require ongoing self-management. Moreover, patients with COPD are typically older and have lower health literacy. OBJECTIVE: This study aimed to obtain and present an overview of patients' perspectives of PWPs to facilitate the development of a portal that better meets the needs of patients with asthma and COPD. METHODS: We performed a focus group study using semistructured interviews in 3 patient groups from the north of the Netherlands who were recruited through the Dutch Lung Foundation. Each group met 3 times for 2 hours each at a 1-week interval. Data were analyzed with coding software, and patient descriptors were analyzed with nonparametric tests. The consolidated criteria for reporting qualitative research were followed when conducting the study. RESULTS: We included 29 patients (16/29, 55% male; mean age 65 [SD 10] years) with COPD (n=14), asthma-COPD overlap (n=4), asthma (n=10), or other respiratory disease (n=1). There was a large variation in the internet experience; some patients hardly used the internet (4/29, 14%), whereas others used internet >3 times a week (23/29, 79%). In general, patients were positive about having access to a PWP, considering access to personal medical records as the most important option, though only after discussion with their physician. A medication overview was considered a useful option. We found that communication between health care professionals could be improved if patients could use the PWP to share information with their health care professionals. However, as participants were worried about the language and usability of portals, it was recommended that language should be adapted to the patient level. Another concern was that disease monitoring through Web-based questionnaire use would only be useful if the results were discussed with health care professionals. CONCLUSIONS: Participants were positive about PWPs and considered them a logical step. Today, most patients tend to be better educated and have internet access, while also being more assertive and better informed about their disease. A PWP could support these patients. Our participants also provided practical suggestions for implementation in current and future PWP developments. The next step will be to develop a portal based on these recommendations and assess whether it meets the needs of patients and health care providers

ERS International Congress 2020::Highlights from the General Pneumology Assembly

The European Respiratory Society (ERS) accepted 4062 abstracts for presentation at the ERS International Congress in 2020. Although the conference was held virtually, making it possible to replay presentations, it remains a challenge to keep abreast of all the clinical and scientific advances. Therefore, this article provides highlights from the General Pneumology Assembly. Selected presentations from rehabilitation and chronic care, general practice and primary care, and electronic/mobile health (e-health/m-health) are summarised. The highlights incorporate novel findings from laboratory-based science, randomised controlled trials and qualitative research together with insights from newly available clinical guidelines

Mapping the clinical chronic obstructive pulmonary disease questionnaire onto generic preference-based EQ-5D values

Objectives To develop a model to predict EuroQol five-dimensional questionnaire (EQ-5D) values from clinical chronic obstructive pulmonary disease (COPD) questionnaire (CCQ) scores. Methods We used data from three clinical trials (the Randomized Clinical Trial on Effectiveness of Integrated COPD Management in Primary Care [RECODE], the Assessment Of Going Home Under Early Assisted Discharge [GO-AHEAD], and the Health Status Guided COPD Care [MARCH]). Data were randomly split into an estimation sample and a validation sample. The conceptual similarity between patient-reported CCQ and preference-based EQ-5D scores was assessed using correlation and principal-component analysis. Different types of models were estimated with increasing complexity. We selected the final models on the basis of mean absolute error and root mean square error when comparing predicted and observed values from the same population (internal validity) and from different trial populations (external validity). We also developed models for different country-specific EQ-5D value sets. Results The principal-component analysis showed that the CCQ domains functional state and mental state are associated with four dimensions of the EQ-5D. The EQ-5D dimension pain/discomfort formed a separate construct on which no CCQ item loaded. The mean observed EQ-5D values were not significantly different from the mean predicted EQ-5D values in internal validation samples but did significantly differ in external validation samples. The models underestimated EQ-5D values in milder health states and overestimated them in more severe health states. The predictive ability of the models was similar across different EQ-5D value sets. Conclusions The models can predict mean EQ-5D values that are similar to observed mean values in a similar population. The overestimating/underestimating of the low/high EQ-5D values, however, limits its use in Markov models. Therefore, mapping should be used cautiously

Health status in routine clinical practice: validity of the clinical COPD questionnaire at the individual patient level

<p>Abstract</p> <p>Background</p> <p>There is a growing interest to use health status or disease control questionnaires in routine clinical practice. However, the validity of most questionnaires is established using techniques developed for group level validation. This study examines a new method, using patient interviews, to validate a short health status questionnaire, the Clinical COPD Questionnaire (CCQ), at the individual patient level.</p> <p>Methods</p> <p>Patients with COPD who visited an outpatient clinic completed the CCQ before the consultation, and the specialist physician completed it after the consultation. After the consultation all patients had a semi-structured in-depth interview. The patients' CCQ scores were compared with those of the treating clinician, and with mean scores from 5 clinicians from a pool of 20 who scored the CCQ after reading the transcript of the in-depth interviews only. Agreement was assessed using Lin's concordance correlation coefficient (CCC), and Blant and Altman plots. Interviews with patients with low agreement were reviewed for possible explanations.</p> <p>Results</p> <p>A total of 44 COPD patients (32 male, mean age 66 years, FEV₁45% of predicted) participated. Agreement between the patients' CCQ scores and those of the treating clinicians (CCC = 0.87) and the mean score of the reviewing clinicians (CCC = 0.86) was very high. No systematic error was detected. No explanation for individuals with low agreement was found.</p> <p>Conclusion</p> <p>The validity of the CCQ on the individual patient level, as assessed by these methods, is good. Individual health status assessment with the CCQ is therefore sufficiently accurate to be used in routine clinical practice.</p
