RESUMO
BACKGROUND: People with secondary progressive multiple sclerosis (pwSPMS) experience increasing disability, which impacts negatively on their health-related quality of life (HRQoL). Our aims were to assess the impact of secondary progressive multiple sclerosis (SPMS) on functional status and HRQoL and describe the clinical profile in this population. METHODS: DISCOVER is an observational, cross-sectional, multicenter study with retrospective data collection in real-world clinical practice in Spain. Sociodemographic and clinical variables, functional and cognitive scales, patient-reported outcomes (PROs), and direct healthcare, and non-healthcare and indirect costs were collected. RESULTS: A total of 297 evaluable pwSPMS with a EDSS score between 3-6.5 participated: 62.3 % were female and 18.9 % had active SPMS. At the study visit, 77 % of them presented an Expanded Disability Scale Score (EDSS) of 6-6.5. Nearly 40 % did not receive any disease-modifying treatment. Regarding the working situation, 61.6 % were inactive due to disability. PROs: 99.3 % showed mobility impairment in EuroQoL-5 Dimensions-5 Levels, and about 60 % reported physical impact on the Multiple Sclerosis Impact Scale-29. Fatigue was present in 76.1 %, and almost 40 % reported anxiety or depression. The Symbol Digit Modalities Test was used to assess cognitive impairment; 80 % of the patients were below the mean score. Participants who presented relapses two years before and had high EDSS scores had a more negative impact on HRQoL. PwSPMS with a negative impact on HRQoL presented a higher cost burden, primarily due to indirect costs. CONCLUSIONS: PwSPMS experience a negative impact on their HRQoL, with a high physical impact, fatigue, cognitive impairment, and a high burden of indirect costs.
RESUMO
BACKGROUND: The treatment landscape for neuromyelitis optica spectrum disorder (NMOSD) has changed in recent years with the approval of therapies with different efficacy, safety and administration profiles. OBJECTIVE: The aim of this study was to assess neurologists' preferences for different NMOSD treatment attributes using conjoint analysis (CA). METHODS: We conducted an online, non-interventional, cross-sectional study in collaboration with the Spanish Society of Neurology. Our CA assessed five drugs' attributes: prevention of relapse, prevention of disability accumulation, safety risk, management during pregnancy, and route and frequency of administration. Participants were presented with eight hypothetical treatment scenarios to rank based on their preferences from the most preferred to the least. An ordinary least squares method was selected to estimate weighted preferences. RESULTS: A total of 104 neurologists were included. Mean age (standard deviation-SD) was 37.7 (10.3) years, 52.9 % were male, and median time (interquartile range) of experience managing NMOSD was 5.0 (2.9, 10.8) years. Neurologists placed the greatest importance on efficacy attributes, time to relapse (44.1 %) being the most important, followed by preventing disability accumulation (36.8 %). In contrast, route and frequency of administration (4.6 %) was the least important characteristic. Participants who prioritised efficacy attributes felt more comfortable in decision-making, had fewer past experiences of care-related regret and a lower attitude to risk taking than their counterparts. CONCLUSION: Neurologists' treatment preferences in NMOSD were mainly driven by efficacy attributes. These results may be useful to design policy decisions and treatment guidelines for this condition.

Introduction and objective: Limited information is available on how neurologists make therapeutic decisions in neuromyelitis optica spectrum disorder (NMOSD), especially when new treatments with different mechanisms of action, administration, and safety profile are being approved. Decision-making can be complex under this uncertainty and may lead to therapeutic inertia (TI), which refers to lack of treatment initiation or intensification when therapeutic goals are not met. The study aim was to assess neurologists' TI in NMOSD. Methods: An online, cross-sectional study was conducted in collaboration with the Spanish Society of Neurology. Neurologists answered a survey composed of demographic characteristics, professional background, and behavioral traits. TI was defined as the lack of initiation or intensification with high-efficacy treatments when there is evidence of disease activity and was assessed through five NMOSD aquaporin-4 positive (AQP4+) simulated case scenarios. A multivariate logistic regression analysis was used to determine the association between neurologists' characteristics and TI. Results: A total of 78 neurologists were included (median interquartile range [IQR] age: 36.0 [29.0-46.0] years, 55.1% male, median [IQR] experience managing demyelinating conditions was 5.2 [3.0-11.1] years). The majority of participants were general neurologists (59.0%) attending a median (IQR) of 5.0 NMOSD patients (3.0-12.0) annually. Thirty participants (38.5%) were classified as having TI. Working in a low complexity hospital and giving high importance to patient's tolerability/safety when choosing a treatment were predictors of TI. Conclusion: TI is a common phenomenon among neurologists managing NMOSD AQP4+. Identifying TI and implementing specific intervention strategies may be critical to improving therapeutic decisions and patient care.
