Clinical outcomes in patients receiving edoxaban or phenprocoumon for prevention of stroke in atrial fibrillation: a German real-world cohort study.

BACKGROUND: Appropriate and timely anticoagulant therapy with vitamin K antagonists (VKAs) or non-vitamin K oral antagonists (NOACs) is essential for stroke prevention in non-valvular atrial fibrillation (NVAF). Comparative data regarding effectiveness and safety for edoxaban vs phenprocoumon, the predominant VKA in Germany, are scarce. OBJECTIVES: The study evaluates effectiveness and safety of edoxaban vs phenprocoumon in NVAF patients in a German real-world setting. METHODS: German statutory health insurance claims data of the Institute for Applied Health Research Berlin (InGef) Research Database from 2014 until 2019 were analyzed. In NVAF patients, new users of edoxaban and phenprocoumon were compared to assess effectiveness (stroke/systemic embolism (SE)) and safety (bleeding) during therapy. Hazard ratios (HR) were estimated through multiple outcome-specific cox proportional hazard models adjusting for baseline characteristics. Outcomes of geriatric patients were analyzed in subgroup analyses. RESULTS: Between 2015 and 2018, 7,975 and 13,319 NVAF patients newly initiated treatment with edoxaban or phenprocoumon. After adjusting for baseline confounders, the risk of stroke/SE (HR: 0.85, 95% CI: 0.70-1.02) was numerically but not significantly lower, while the risk of major bleeding (HR: 0.69, 95% CI: 0.58-0.81) was significantly lower for edoxaban. In the geriatric subgroups, homogenous results compared to the main analysis were obtained. CONCLUSION: The results of this real-world analysis indicated better effectiveness and safety outcomes in patients with NVAF initiating edoxaban treatment compared to phenprocoumon. The findings confirm that the beneficial effects observed in the pivotal ENGAGE AF-TMI 48 trial can also be achieved in real-world use of edoxaban.

Safety and Persistence of Nalmefene Treatment for Alcohol Dependence. Results from Two Post-authorisation Safety Studies.

AIMS: Two post-authorisation studies assessed the safety and persistence of patients' use of nalmefene. METHODS: The START study (EUPAS5678) was a non-interventional, multi-country, prospective, 18-month (8 follow-up visits) cohort study including outpatients initiating nalmefene for the first time. The multi-database retrospective cohort study (MDRC, EUPAS14083) included baseline and follow-up data from German, Swedish and UK healthcare databases. Both studies permitted 'all comers' without explicit exclusion criteria; predefined subgroups of interest included the elderly (≥65 years) as well as patients with significant psychiatric and/or somatic comorbidities. RESULTS: START study: Overall, the mean duration of nalmefene treatment was 10.3 ± 7.3 months (N = 1348), with 49.0% of patients treated for ≥1 year; frequent reasons for treatment discontinuation were 'goal reached' and 'drug cost'. The most frequently reported adverse drug reactions (ADRs) were nausea (4.7%), dizziness (3.2%) and insomnia (2.0%). ADR rates appeared higher in the elderly subpopulation (18.6% reported ≥1 ADR vs. 12.0% in the total population) but were not higher in the other predefined subgroups.MDRC study: The database follow-up analysis followed 2892 patients over 18 months for whom the duration of nalmefene treatment was between 2 and 3 months and <5% of patients used nalmefene for ≥1 year. CONCLUSIONS: Despite the inclusion of a wider patient population (e.g. elderly patients and those with relevant co-morbidities), the safety and tolerability profile of nalmefene given in routine practice was consistent with previous clinical studies. The differing rates of persistence beyond 1 year likely reflect the different methodologies and highlight the relevance of psychosocial support at follow-up visits.

Subjective perception of craniofacial growth asymmetries in patients with deformational plagiocephaly.

OBJECTIVES: The present investigation aimed to evaluate the subjective perception of deformational cranial asymmetries by different observer groups and to compare these subjective perceptions with objective parameters. MATERIALS AND METHODS: The 3D datasets of ten infants with different severities of deformational plagiocephaly (DP) were presented to 203 observers, who had been subdivided into five different groups (specialists, pediatricians, medical doctors (not pediatricians), parents of infants with DP, and laypersons). The observers rated their subjective perception of the infants' cranial asymmetries using a 4-point Likert-type scale. The ratings from the observer groups were compared with one another using a multilevel modelling linear regression analysis and were correlated with four commonly used parameters to objectively quantify the cranial asymmetries. RESULTS: No significant differences were found between the ratings of the specialists and those of the parents of infants with DP, but both groups provided significantly more asymmetric ratings than did pediatricians, medical doctors, or laypersons. Moreover, the subjective perception of cranial asymmetries correlated significantly with commonly used parameters for objectively quantifying cranial asymmetries. CONCLUSIONS: Our results demonstrate that different observer groups perceive the severity of cranial asymmetries differently. Pediatricians' more moderate perception of cranial asymmetries may reduce the likelihood of parents to seek therapeutic interventions for their infants. Moreover, we identified some objective symmetry-related parameters that correlated strongly with the observers' subjective perceptions. CLINICAL RELEVANCE: Knowledge about these findings is important for clinicians when educating parents of infants with DP about the deformity.

Ankylosing spondylitis causes high burden to patients and the healthcare system: results from a German claims database analysis.

To compare healthcare resource utilization and costs between ankylosing spondylitis (AS) patients and a matched sample from the general population without AS covered by the German Statutory Health Insurance (SHI) system, a non-interventional retrospectively matched cohort analysis was conducted using anonymized SHI claims data. Data from January 1st, 2011 through December 31st, 2014 were analyzed. Individuals with a coded diagnosis of AS during the enrollment period comprising the full year of 2013 were directly matched (1:5) to individuals without AS diagnosis in the whole study period by age, gender, hospitalizations, and comorbidities. All-cause healthcare resource utilization and direct costs were analyzed for the year 2013. Statistical tests were applied to compare the differences between the two sampled populations. In 2013, 10,208 AS patients were identified and matched to a sample of 51,040 patients without AS from the general population. Healthcare resource utilization was significantly higher in all healthcare sectors (inpatient, outpatient, pharmaceuticals, remedies, devices and aids, and sick leave) in the AS cohort. Mean all-cause healthcare costs per patient were about €2475 higher in the AS cohort compared to the general population. Most important cost drivers were hospitalizations and pharmaceuticals in terms of bDMARDs prescribed in 10% of the patients. Real-world data from this German claims database analysis showed that AS is associated with a substantial incremental economic burden to the healthcare system.

Natural History of Visual Acuity and Microperimetry-Based Functional Outcome Measures of the Macula in Patients with Geographic Atrophy: A Retrospective Chart Review Study in Germany.

Background/Objectives: Geographic atrophy (GA) is an advanced form of age-related macular degeneration (AMD) leading to the progressive and irreversible loss of visual function. Characteristics of GA include atrophic lesions resulting from the loss of photoreceptors, retinal pigment epithelium, and choriocapillaris. During GA progression, atrophic lesions typically advance from the macular periphery to the center, affecting foveal light sensitivity and visual acuity. This study analyzed changes in light sensitivity and visual acuity during the natural course of GA progression using the topographic analysis of structural and functional changes based on Early Treatment Diabetic Retinopathy Study (ETDRS) charts, multimodal imaging, and microperimetry assessment. Methods: Medical chart data of GA patients between 2014 and 2022 from the Internationale Innovative Ophthalmochirurgie GbR (I.I.O.) research center (Düsseldorf, Germany) were retrospectively analyzed. All patient eyes fulfilling the phase 3 OAKS study inclusion criteria were included and followed up for 60 months. The imputation of missing measurements and dropouts was performed by linear mixed models. Results: A total of 20 GA eyes from 13 GA patients were included in the study. At the index, 53.8% of patients had bilateral GA, with 70.0% of the eyes showing multifocal GA and 30.0% subfoveal encroachment (SFE). A total of 35.0% of the eyes had 2-5, and 15.0% over 20, areas of atrophy. Over time, the GA lesion size increased from 6.4 mm2 to 11.8 mm2 (1.08 mm2/year). After an average observation time of 2.9 years, 78.6% of the initially unaffected study eyes developed SFE. The percentage of study eyes without visual impairment decreased from 55.0% to 30.0%, with mean normal-luminance best-corrected visual acuity (NL-BCVA) reducing from 63.7 to 55.7 ETDRS letters. The share of absolute scotoma points in microperimetry assessment increased from 15.7% to 43.5% while overall average macular sensitivity declined from 15.7 dB to 7.4 dB. Conclusions: The substantial deterioration of macular outcomes and visual function was comprehensively detected. The results were a documentation of structural and functional aspects of the natural progression of GA for a 60-month follow-up, providing a typical outline for AMD patients with GA.

Treatment with the SQ tree sublingual immunotherapy tablet is safe and well tolerated in real-life.

BACKGROUND: The SQ tree sublingual immunotherapy (SLIT)-tablet is authorised for treatment of allergic rhinoconjunctivitis with or without asthma in trees of the birch homologous group in 21 European countries. The primary objective of this study was to explore the safety in real-life. METHODS: In a prospective, non-interventional post-authorisation safety study (EUPAS31470), adverse events (AEs) and adverse drug reactions (ADRs) at first administration and follow-up visits, symptoms, medication use, and pollen food syndrome were recorded by physicians in 6 European countries during the first 4-6 months of treatment. RESULTS: ADRs with the SQ tree SLIT-tablet were reported in 57.7% of 1069 total patients (median age 36.0 years, 53.7% female) during the entire observation period (severity, mild-to-moderate: 70.1%, severe: 4.7%, serious: 0.7%) and in 45.9% after first administration. ADRs were not increased with pollen exposure at first administration. With coadministration of the SQ tree and grass SLIT-tablet AEs were reported in 73.8% of patients and in 52.8% with the SQ tree SLIT-tablet alone. Nasal and eye symptoms improved in 86.9% and 80.9% of patients and use of symptomatic medication in 76.0%. PFS with symptoms was reported in 43.0% of patients at baseline and in 4.3% at the individual last visit. CONCLUSIONS: The results of this non-interventional safety study with the SQ tree SLIT-tablet confirm the safety profile from placebo-controlled clinical trials and support effectiveness in real-life according to the published efficacy data. Safety was not impaired by pollen exposure at first administration or co-administration with other SLIT-tablets.

Did the change of the vaccination schedule effect pneumococcal conjugate vaccination compliance and adherence of premature and mature born infants in Germany? Answers from a claims database analysis.

BACKGROUND: In August 2015, the German Standing Committee on Vaccination (STIKO) changed the pneumococcal conjugate vaccination (PCV) schedule for mature infants from a 3+1 to a 2+1scheme. For premature infants, the 3+1schedule remained unchanged. Aim was to assess vaccination rates, completeness, and timeliness for PCV stratified by premature and mature infants before and after the recommendation change based on real-world data. METHODS: Retrospective claims data analyses were conducted using a comprehensive research database. The study population consisted of all mature and premature infants born in 2013, 2016, or 2018 with an individual follow-up of 24 months using ICD-10-GM codes P07.2 and P07.3 for premature infants. Hexavalent (HEXA) combination vaccination with a consistent 3+1recommendation for premature and mature infants was analyzed as a reference. RESULTS: After follow-up of 24 months, rates of premature and mature infants receiving ≥1PCV and HEXA vaccination steadily increased since the change of STIKO's recommendation. However, in 2018 (2016/2013), only 47 % (41 %/65 %) of premature but 74 % (72 %/68 %) of mature infants obtained the recommended 3+1 respectively 2+1 PCV doses. At the same age, a consistent increase in complete HEXA vaccination with 3+1 doses was observed over time in premature (2013/2016/2018: 66 %/68 %/70 %) and mature (2013/2016/2018: 69 %/72 %/73 %) infants. Timeliness of PCV and HEXA booster administration remained stable with âˆ¼50 % of all premature and mature infants receiving the booster according to recommended timelines. CONCLUSION: There is no proven evidence that the reduced PCV schedule for mature infants induced a higher acceptance of vaccination. The rate of unvaccinated infants remained at a considerable level and vaccinations were often delayed. Although the STIKO still recommends a 3+1 PCV schedule for premature infants in Germany, less than half of children showed a completed vaccination series. To protect these vulnerable groups, efforts are needed to increase adherence to the STIKO recommendation especially for premature infants.

European multicenter study on the real-world use and clinical impact of extracorporeal photopheresis after heart transplantation.

BACKGROUND: Aim of this study was to describe the real-world use of extracorporeal photopheresis (ECP) and assess its impact on clinical outcomes in the modern era of heart transplantation. METHODS: Seven transplant centers from 5 European countries participated in this retrospective, observational, single-arm chart review study. All patients received ECP after heart transplantation in 2015 or later. Data were extracted from medical records between November 2020 and December 2021. RESULTS: Overall, 105 patients were enrolled and followed for an average of 2 years after initiation of ECP. Reasons to start ECP were acute cellular rejection (35.2%), rejection prevention (32.4%), mixed rejection (18.1%), and antibody-mediated rejection (14.3%). Rejection ISHLT grades improved from start to end of ECP treatment in 92% of patients treated with ECP for rejection. Of patients who started ECP to prevent rejection, 88% remained free from any rejection despite a reduction of calcineurin inhibitors. Overall survival was 95%, and no deaths were related to ECP. Safety events occurred in 18 patients, of which 13 experienced complications with venous access. CONCLUSIONS: This study, the largest European ECP study in heart transplantation, demonstrates that ECP can effectively be used to treat different rejection types and to prevent rejection in the modern era of immunosuppression. Patients with rejections who have received ECP have shown high response as measured by histological improvements in ISHLT classification. A high percentage of patients in the prevention group remained free from rejection despite reduction in immunosuppression, in particular calcineurin inhibitors.

Health Resource Utilization and Associated Health Care Costs of Biologic Disease-Modifying Antirheumatic Drugs in German Patients With Psoriatic Arthritis.

OBJECTIVE: To investigate health care costs associated with biologic disease-modifying antirheumatic drugs (bDMARDs) in a German real-world cohort of adult biologics-naive patients with psoriatic arthritis (PsA). METHODS: Claims data from the Institute for Applied Health Research Berlin (InGef) research database for patients with a PsA diagnosis and bDMARD claims record (index date) between January 1, 2014, and December 31, 2017, and no bDMARD prescriptions for 365 days before the index date were retrospectively analyzed. Primary outcomes were determination of health care resource utilization and associated annual health care costs for overall and individual bDMARDs in the 12-month pre-index and post-index periods. These outcomes were compared between persistent and nonpersistent groups. Nonpersistence was defined as treatment gap or switch to a bDMARD other than the index therapy. RESULTS: Among 10,954 patients with a PsA diagnosis, 348 were eligible. Although mean ± SD post-index costs were significantly higher in the persistent group than the nonpersistent group (€27,869 ± 8,001 versus €21,897 ± 10,600, P < 0 .001) due to higher bDMARD acquisition costs (€23,996 ± 4,818 versus €16,427 ± 9,033, P < 0.001), persistence reduced inpatient treatment costs (-€760), outpatient treatment costs (-€192), other drug costs (-€724), and sick leave costs (-€601). CONCLUSION: Although initiation of bDMARDs increased the total health care costs irrespective of persistence status, partial cost offsets were observed in the persistent patient population.

Real-World Treatment Persistence with Biologic Disease-Modifying Antirheumatic Drugs Among German Patients with Psoriatic Arthritis-A Retrospective Database Study.

INTRODUCTION: To investigate drug survival for biologic disease-modifying antirheumatic drugs (bDMARDs) in a real-world cohort of German adult biologic-naïve patients with psoriatic arthritis (PsA). METHODS: Claims data for patients with a diagnosis of PsA, a bDMARD claims record (index date) between 1 January 2014 and 31 December 2017, and no bDMARD prescription for 365 days before the index date were retrospectively analyzed. The primary outcomes were the overall and individual bDMARD persistence rates over 12 months. Nonpersistence was defined as a treatment gap exceeding the days of supply plus 60 days or switching to a bDMARD other than the index therapy. Sensitivity analysis was performed, wherein the treatment gap was found to vary depending on the bDMARD regimen. Kaplan-Meier curves were plotted to determine persistence; the log-rank test was used to evaluate differences in the persistence rate. Factors associated with treatment discontinuation were evaluated using Cox regression analysis. RESULTS: Among 10,954 patients with a PsA diagnosis, 348 were eligible. The overall bDMARD persistence rate was 57.5%; individual bDMARD persistence rates were 81.3% for ustekinumab, 66.7% for infliximab, and 60.0% for golimumab. The mean (SD) overall persistence with bDMARDs was 289 (103) days; the mean persistence was 334 (72) days for ustekinumab, 309 (82) days for golimumab, and 305 (92) days for infliximab. The main reasons for nonpersistence were switching to another bDMARD (15.8%) and treatment discontinuation (26.7%). Male gender was significantly associated with a lower risk of treatment discontinuation (hazard ratio 0.54, 95% confidence interval 0.39-0.77; P < 0.001). The sensitivity analysis yielded similar results. CONCLUSION: The one-year persistence rate for bDMARDs in German PsA patients is modest, although the persistence rate depends on the bDMARD considered.

Vaccination rates and adherence in pneumococcal conjugate vaccination in mature born infants before and after vaccination schedule change - A claims database analysis.

BACKGROUND: In August 2015, the German Standing Committee on Vaccination (STIKO) changed the pneumococcal conjugate vaccination (PCV) schedule for mature infants from a 3+1 scheme to a 2+1 scheme. It was expected that a reduction of doses would be associated with a higher acceptance of the vaccination. Aim of this study was to assess vaccination rates and adherence for PCV after the change of recommendation based on real-world data. METHODS: A retrospective claims data analysis using the InGef Research Database was conducted. The study population consisted of all mature infants born in 2013 (last birth cohort completely under 3+1 recommendation) or 2016 (first birth cohort completely under 2+1 recommendation) with an individual follow-up of 24 months. Hexavalent combination vaccination (HEXA) with a consistent 3+1 recommendation was analyzed as reference. RESULTS: After follow-up of 24 months, 90.9% (91.2%) of the 2016 (2013) cohort received at least one dose of PCV. At the same age, 67.7% of the 2013 cohort received a booster dose according to the 3+1 schedule and 75.6% of the 2016 cohort received a booster dose presumably either according to the 2+1 (71.7%) or 3+1 (3.9%) schedule. Of those receiving the booster dose, only 46.3% (2016) and 45.1% (2013) received the booster dose on time as recommended. The HEXA vaccination rate increased from 88.9% (2013) to 91.6% (2016) with a full series completion in 69.1% (2013) vs 72.9% (2016). The proportion of infants receiving the booster vaccination on time rose to 50.0% in 2016 (47.8% in 2013). CONCLUSIONS: Although the rate for the PCV booster dose slightly increased, nearly a quarter of the infants born in 2016 did not receive a booster dose at all. Furthermore, vaccinations were still frequently delayed, and the rate of unvaccinated infants remained constant.

Vaccination rates and adherence in premature infants before and after pneumococcal conjugate vaccine schedule change for term infants - A claims database analysis in Germany.

BACKGROUND: In 2015, the German Standing Committee on Vaccination (STIKO) changed the pneumococcal conjugate vaccination (PCV) schedule for mature infants from a 3+1scheme (2, 3, 4, and 11-14 months of age) to a 2+1scheme (2, 4, and 11-14 months of age). For premature infants, the 3+1scheme remained. The aim of this study was to assess vaccination rates, completeness, and timeliness for PCV in premature infants before and after the modified recommendation. METHODS: A retrospective claims data analysis using the "Institut für angewandte Gesundheitsforschung Berlin" Research Database was conducted. Premature infants born in 2013 and 2016 with an individual follow-up of 24 months were included. Hexavalent combination (HEXA) vaccination with a consistent 3+1recommendation for mature and premature infants was analyzed as reference vaccination. RESULTS: After 24 months, the PCV rate for at least one dose remained stable in premature newborns of 2016 compared to 2013, while the HEXA vaccination rate increased slightly. However, a significant decrease of a completed PCV schedule (4 doses) in premature infants was noted, whereas the completeness of HEXA vaccination did not change. The timeliness of PCV in premature newborns increased for the first and the booster PCV, while the timeliness of HEXA immunization did not change from 2013 to 2016. CONCLUSION: Although STIKO still recommends a 3+1PCV schedule for premature infants in Germany, premature infants were vaccinated according to the changed recommendations for mature born infants. A substantial share of premature infants remained unvaccinated, and their vaccinations were often delayed.

Application study of the EQ-5D-5L in oncology: linking self-reported quality of life of patients with advanced or metastatic colorectal cancer to clinical data from a German tumor registry.

BACKGROUND: The EQ-5D-5L questionnaire is used in oncology to generate health-related quality of life (HRQoL) weights and corresponding health states. The purpose was to explore the relationship between demographic and clinical characteristics and HRQoL among advanced or metastatic colorectal cancer (CRC) patients by linking clinical data of a German CRC registry to self-reported HRQoL measures from the EQ-5D-5L. METHODS: The study sample included patients with advanced or metastatic CRC currently recruited in the German Tumor Registry Colorectal Cancer. The EQ-5D-5L was administered once to patients who were at the start or at later stages of palliative treatment. Data on comorbidities, disease-specific health states, symptoms, and treatment status were drawn from the registry. Multivariate regression analyses were performed to explore the impact of patient and disease characteristics on HRQoL. RESULTS: In total, n = 433 questionnaires were included in the data analysis. Mean age of patients was 66.3 years and 61.2% were male. The mean EQ-5D-5L utility score was 0.82 and the mean EQ-5D-5L VAS score was 62.05. The regression analyses revealed that none of the demographic characteristics and few of the clinical characteristics, such as fatigue and pain, had a significant impact on the HRQoL. CONCLUSIONS: The study demonstrated a reduced HRQoL of patients with advanced or metastatic CRC when compared to the general population. The symptoms fatigue and pain negatively affected the HRQoL, whereas other characteristics such as age, gender, and comorbidities did not have a significant impact on HRQoL.

Oral versus intravenous iron therapy in patients with inflammatory bowel disease and iron deficiency with and without anemia in Germany - a real-world evidence analysis.

BACKGROUND: Iron-deficiency anemia and iron deficiency are common comorbidities associated with inflammatory bowel disease (IBD) resulting in impaired quality of life and high health care costs. Intravenous iron has shown clinical benefit compared to oral iron therapy. AIM: This study aimed to compare health care outcomes and costs after oral vs intravenous iron treatment for IBD patients with iron deficiency or iron deficiency anemia (ID/A) in Germany. METHODS: IBD patients with ID/A were identified by ICD-10-GM codes and newly commenced iron treatment via ATC codes in 2013 within the InGef (formerly Health Risk Institute) research claims database. Propensity score matching was performed to balance both treatment groups. Non-observable covariates were adjusted by applying the difference-in-differences (DID) approach. RESULTS: In 2013, 589 IBD patients with ID/A began oral and 442 intravenous iron treatment. After matching, 380 patients in each treatment group were analyzed. The intravenous group had fewer all-cause hospitalizations (37% vs 48%) and ID/A-related hospitalizations (5% vs 14%) than the oral iron group. The 1-year preobservation period comparison revealed significant health care cost differences between both groups. After adjusting for cost differences by DID method, total health care cost savings in the intravenous iron group were calculated to be €367. While higher expenditure for medication (€1,876) was observed in the intravenous iron group, the inpatient setting achieved most cost savings (€1,887). CONCLUSION: IBD patients receiving intravenous iron were less frequently hospitalized and incurred lower total health care costs compared to patients receiving oral iron. Higher expenditures for pharmaceuticals were compensated by cost savings in other domains.

Patient preferences in allergy immunotherapy (AIT) in Germany - a discrete-choice-experiment.

BACKGROUND: Allergic Rhinitis (AR) is a common disorder in Europe with Allergic Asthma (AA) as a frequent comorbidity. Allergy immunotherapy (AIT) is the only causal therapy of AR and AA, and can be administered as subcutaneous injections at the physician or as sublingual drops or tablets at home. The usual treatment duration is 3 years. OBJECTIVE: This study aimed to elicit patient preferences to identify the AIT administration mode preferred by patients. METHODS: A discrete-choice-experiment (DCE) was developed to determine how people weight different treatment options using a paper-based questionnaire from June to September 2014, including 16 study centres. Main inclusion criteria: >18 years, grass, birch and/or house dust mite AR with moderate to severe symptoms, AIT-naïve and AIT-indicated. DCE-attributes were: Administration form, number and duration of physician visits, frequency of life-threatening anaphylactic shocks, local side-effects and co-payments. RESULTS: Two-hundred thirty-nine subjects participated, resulting in analysable 1842 choices. All attributes were significant predictors for the treatment-choice. Ranked by importance, the following first three attributes are most preferred by patients: 1(st) Number and duration of physician visits: Fewer visits with shorter duration preferred (0.658*) 2(nd) Frequency of life-threatening anaphylactic shocks: Lower risk of shocks preferred (0.285*) 3(rd) Local side-effects: Preference for rash/swelling on upper arm over itching/swelling under the tongue (0.210*) (*coefficient-size represents relative importance of the attributes) CONCLUSION: The most important attribute is the number and duration of visits to a physician. A lower risk of life-threatening anaphylactic shocks was ranked as the second whereas co-payments and administration form play a limited role.
