RESUMO
OBJECTIVES: The Munich Breathlessness Service (MBS) significantly improved control of breathlessness measured by the Chronic Respiratory Questionnaire (CRQ) Mastery in a randomized controlled fast track trial with waitlist group design spanning 8 weeks in Germany. This study aimed to assess the within-trial cost-effectiveness of MBS from a societal perspective. METHODS: Data included generic (5-level version of EQ-5D) health-related quality of life and disease-specific CRQ Mastery. Quality-adjusted life years (QALYs) were calculated based on 5-level version of EQ-5D utilities valued with German time trade-off. Direct medical costs and productivity loss were calculated based on standardized unit costs. Incremental cost-effectiveness ratios (ICER) and cost-effectiveness-acceptance curves were calculated using adjusted mean differences (AMD) in costs (gamma-distributed model) and both effect parameters (Gaussian-distributed model) and performing 1000 simultaneous bootstrap replications. Potential gender differences were investigated in stratified analyses. RESULTS: Between March 2014 and April 2019, 183 eligible patients were enrolled. MBS intervention demonstrated significantly better effects regarding generic (AMD of QALY gains of 0.004, 95% confidence interval [CI] 0.0003 to 0.008) and disease-specific health-related quality of life at nonsignificantly higher costs (AMD of 605 [95% CI -1109 to 2550]). At the end of the intervention, the ICER was 152 433/QALY (95% CI -453 545 to 1 625 903) and 1548/CRQ Mastery point (95% CI -3093 to 10 168). Intervention costs were on average 357 (SD = 132). Gender-specific analyses displayed dominance for MBS in males and higher effects coupled with significantly higher costs in females. CONCLUSIONS: Our results show a high ICER for MBS. Considering dominance for MBS in males, implementing MBS on approval within the German health care system should be considered.

OBJECTIVES: At 3 months after the intervention, this study evaluates the cost-effectiveness of a 3-week inpatient pulmonary rehabilitation (PR) in patients with asthma compared with usual care alongside the single-center randomized controlled trial-Effectiveness of Pulmonary Rehabilitation in Patients With Asthma. METHODS: Adopting a societal perspective, direct medical costs and productivity loss were assessed using the Questionnaire for Health-Related Resource Use-Lung, a modification of the FIM in an Elderly Population. The effect side was operationalized as minimal important differences (MIDs) of the Asthma Control Test (ACT) and the Asthma Quality of Life Questionnaire (AQLQ) and through quality-adjusted life-years (QALYs) gained. Adjusted mean differences in costs (gamma-distributed model) and each effect parameter (Gaussian-distributed model) were simultaneously calculated within 1000 bootstrap replications to determine incremental cost-effectiveness ratios (ICERs) and to subsequently delineate cost-effectiveness acceptability curves. RESULTS: PR caused mean costs per capita of 3544. Three months after PR, we observed higher mean costs (Δ3673; 95% confidence interval (CI) 2854-4783) and improved mean effects (ACT Δ1.59 MIDs, 95% CI 1.37-1.81; AQLQ Δ1.76 MIDs, 95% CI 1.46-2.08; QALYs gained Δ0.01, 95% CI 0.01-0.02) in the intervention group. The ICER was 2278 (95% CI 1653-3181) per ACT-MID, 1983 (95% CI 1430-2830) per AQLQ-MID, and 312 401 (95% CI 209 206-504 562) per QALY gained. CONCLUSIONS: Contrasting of PR expenditures with ICERs suggests that the intervention, which achieves clinically relevant changes in asthma-relevant parameters, has a high probability to be already cost-effective in the short term. However, in terms of QALYs, extended follow-up periods are likely required to comprehensively judge the added value of a one-time initial investment in PR.

BACKGROUND: Evidence on the economic impact of chronic obstructive pulmonary disease (COPD) for third-party payers and society based on large real world datasets are still scarce. Therefore, the aim of this study was to estimate the economic impact of COPD severity and its comorbidities, stratified by GOLD grade, on direct and indirect costs for an unselected population enrolled in the structured German Disease Management Program (DMP) for COPD. METHODS: All individuals enrolled in the DMP COPD were included in the analysis. Patients were only excluded if they were not insured or not enrolled in the DMP COPD the complete year before the last DMP documentation (at physician visit), had a missing forced expiratory volume in 1 s (FEV1) measurement or other missing values in covariates. The final dataset included 39,307 patients in GOLD grade 1 to 4. We used multiple generalized linear models to analyze the association of COPD severity with direct and indirect costs, while adjusting for sex, age, income, smoking status, body mass index, and comorbidities. RESULTS: More severe COPD was significantly associated with higher healthcare utilization, work absence, and premature retirement. Adjusted annual costs for GOLD grade 1 to 4 amounted to 3809 [3691-3935], 4284 [4176-4394], 5548 [5328-5774], and 8309 [7583-9065] for direct costs, and 11,784 [11,257-12,318], 12,985 [12,531-13,443], 15,805 [15,034-16,584], and 19,402 [17,853-21,017] for indirect costs. Comorbidities had significant additional effects on direct and indirect costs with factors ranging from 1.19 (arthritis) to 1.51 (myocardial infarction) in direct and from 1.16 (myocardial infarction) to 1.27 (cancer) in indirect costs. CONCLUSION: The findings indicate that more severe GOLD grades in an unselected COPD population enrolled in a structured DMP are associated with tremendous additional direct and indirect costs, with comorbidities significantly increase costs. In direct cost category hospitalization and in indirect cost category premature retirement were the main cost driver. From a societal perspective prevention and interventions focusing on disease control, and slowing down disease progression and strengthening the ability to work would be beneficial in order to realize cost savings in COPD.

BACKGROUND: Risk attitudes influence decisions made under uncertainty. This paper investigates the association of risk attitudes with the utilization of preventive and general healthcare services, work absence and resulting costs to explore their contribution to the heterogeneity in utilization. METHODS: Data of 1823 individuals (56.5 ± 9.5 years), participating in the German KORA FF4 population-based cohort study (2013/2014) were analyzed. Individuals' general and health risk attitude were measured as willingness to take risk (WTTR) on 11-point scales. Utilization of preventive and medical services and work absence was assessed and annual costs were calculated from a societal perspective. Generalized linear models with log-link function (logistic, negative-binomial and gamma regression) adjusted for age, sex, and height were used to analyze the association of WTTR with the utilizations and costs. RESULTS: Higher WTTR was significantly associated with lower healthcare utilization (physician visits, physical therapy, and medication intake), work absence days and indirect costs. Regarding preventive services, an overall negative correlation between WTTR and utilization was examined but this observation remained non-significant except for the outcome medical check-up. Here, higher WTTR was significantly associated with a lower probability of participation. For all associations mentioned, Odds Ratios ranged between 0.90 and 0.79, with p < 0.05. Comparing the two risk attitudes (general and regarding health) we obtained similar results regarding the directions of associations. CONCLUSIONS: We conclude that variations in risk attitudes contribute to the heterogeneity of healthcare utilization. Thus, knowledge of their associations with utilization might help to better understand individual decision-making - especially in case of participation in preventive services.
RESUMO
BACKGROUND: Patients with interstitial lung diseases (ILD) have impaired health-related quality of life (HRQL). Little is known about the applicability of the disease-specific King's Brief Interstitial Lung Disease questionnaire (K-BILD) and the generic EQ-5D-5L in a German setting. METHODS: We assessed disease-specific (K-BILD) and generic HRQL (EQ-5D experience based value set (EBVS) and Visual Analog Scale (VAS)) in 229 patients with different ILD subtypes in a longitudinal observational study (HILDA). Additionally, we assessed the correlation of the HRQL measures with lung function and comorbidities. In a linear regression model, we investigated predictors (including age, sex, ILD subtype, FVC percentage of predicted value (FVC%pred), DLCO percentage of predicted value, and comorbidities). RESULTS: Among the 229 patients mean age was 63.2 (Standard deviation (SD): 12.9), 67.3% male, 24.0% had idiopathic pulmonary fibrosis, and 22.3% sarcoidosis. Means scores were as follows for EQ-5D EBVS 0.66(SD 0.17), VAS 61.4 (SD 19.1) and K-BILD Total 53.6 (SD 13.8). K-BILD had good construct validity (high correlation with EQ-5D EBVS (0.71)) and good internal consistency (Cronbach's alpha 0.89). Moreover, all HRQL measures were highly accepted by patients including low missing items and there were no ceiling or floor effects. A higher FVC % pred was associated with higher HRQL in all measures meanwhile comorbidities had a negative influence on HRQL. CONCLUSIONS: K-BILD and EQ-5D had similar HRQL trends and were associated similarly to the same disease-related factors in Germany. Our data supports the use of K-BILD in clinical practice in Germany, since it captures disease specific effects of ILD. Additionally, the use of the EQ-5D-5L could provide comparison to different disease areas and give an overview about the position of ILD patients in comparison to general population.
