Clinical Trial Summary

Randomized controlled trial to assess the effectiveness and cost-effectiveness of an intervention combining patient initiated care and telemonitoring through the online eHealth platform SpA-Net versus standard care for patients with spondyloarthritis.

Description:

Multicenter randomized controlled trial to investigate the effectiveness and cost-effectiveness of telemonitoring through SpA-Net, in combination with patient initiated care, versus standard care. Participants will be recruited at the outpatient clinics of participating centers, and will be randomised (after informed consent) into either the telemonitoring or standard care group. Patients in both arms will use SpA-Net and will be followed up for 1 year. Concomitantly a trial-based cost-utility analysis will be performed. Randomisation (1:1; intervention versus standard care) is done using the minimisation method, stratifying for medical centre, subtype of SpA (axial, peripheral or combined) and treatment (biological use versus no biological use). Due to the nature of the intervention neither patients nor clinicians can be blinded to the allocation. A sample size of 80 patients per group is necessary to detect the primary outcome with a power of 0.80 and alpha of 0.05. Assuming a 20% drop-out during follow-up, 100 patients per group will be included. This sample size also suffices to show non-inferiority for all secondary objectives with a power of 0.80 and a one-sided alpha of 0.025. Study endpoints A. The primary endpoint is defined as at least 25% reduction in the number of rheumatology department outpatient visits in the intervention group compared to the standard care group, within a 1-year follow-up period. Due to the COVID-19 pandemic these may also take place through telephone or video calls, replacing physical visits. B. Secondary study parameters/endpoints - Non-inferiority of telemonitoring compared to standard care with respect to quality of care and health outcomes. - Non-inferiority with respect to experience with SpA-Net and general rheumatological care. - Association between patient-reported self-management skills and successful application of telemonitoring - Experience with telemonitoring through SpA-Net among care providers - Difference between the populations with regard to healthcare cost per quality adjusted life year (QALY) gained after 1 year - Difference between the populations with regard to societal cost per QALY gained after 1 year STATISTICAL ANALYSIS The primary outcome will be analysed in the intention to treat (ITT) population. The differences between the two groups with respect to quality of care aspects and overall resource utilisation will be analysed in the ITT and the per-protocol (PP) population. All other secondary outcomes will be analysed in the ITT population. The primary endpoint will be compared between both groups with ANOVA. Given that the population is randomised, an equal distribution of baseline characteristics is to be expected. In case differences between the two groups exist on baseline (visually), post-hoc analyses adjusting for these differences will be done (ANCOVA). Secondary endpoints will be analysed with ANOVA. Post-hoc, subgroup analyses and predictive analyses with respect to self-management skills and and successful application of telemonitoring will be done with linear mixed-effect models with each endpoint as dependent variable and time, group and their interaction as fixed effects. Descriptive statistics will be used to summarize experience with telemonitoring among care providers. Non-inferiority margins for secondary outcome measures: - For ASDAS, non-inferiority is defined as an increase of no more than 0.9. - A change in BASDAI of < 2.0 will be considered non-inferior. - A cut-off of 20 millimetres is used for the patient global VAS, and a cut-off of 10 millimetres for the physician global VAS. - An increase in VAS pain of no more than 20 millimetres will be considered non-inferior. - At the time of the study proposal, approximately 90% of the patients is satisfied with the care provided. Non-inferiority is defined as a decrease of no more than 5%. Health economic evaluation will be performed in accordance with the ISPOR guidelines, as well as the current Dutch guidelines for economic evaluations in healthcare. Analyses will be done both from a Dutch healthcare and societal perspective. Currently, no consensus exists with regard to disease weights for SpA. As such, results will be reported for willingness-to-pay thresholds of both 20.000 and 50.000 euros per QALY gained. Sensitivity analyses will be performed to test the robustness of the results gathered. Missing data will be addressed using multiple imputation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Healthcare cost per quality adjusted life year (QALY) gained after 1 year	Self-reported health resource utilisation will be evaluated for two separate 6-month recall periods. Total resource consumption will be reported as the sum of resources utilized during the entire 12-month study period.	1 year
Other	Societal cost per QALY gained after 1 year	To calculate societal costs, self-reported professional absenteeism will be used. Paid productivity loss is valued using the friction cost method as per Dutch national guidelines with a friction period of 85 days. Presenteeism (decreased productivity while at work due to illness) and unpaid productivity loss will be measured and valued based on Dutch costing guidelines.	1 year
Other	Quality Adjusted Life Years (QALY)	To determine incremental cost-utility (iCU), utility will be measured in QALYs. Results from health-related quality of life measures will be converted into utility scores (0-1) to allow calculation of QALYs. Where available, Dutch tariffs will be used.	1 year
Other	Self-management characteristics	As measured by the Self-Management Screening questionnaire (SeMaS) which contains 27 items, assessing a total of 10 domains. Each domain has three possible scores (low = important barrier for self management, middle = unclear/possible barrier for self management, high = self-management likely to be successful). Different combinations of scores result in different patient profiles.	Baseline
Other	Experience with telemonitoring through SpA-Net among care providers	Global satisfaction and agreement on statements (safety, effectiveness, patient-centeredness, timeliness, efficiency, equitability, flexibility, use of time and resources) about telemonitoring with SpA-Net, measured on a 5 point Likert scale (range: 'I strongly agree' to 'I strongly disagree').	1 year
Primary	Number of scheduled and unscheduled outpatient visits to the rheumatology department.	Comparison of total number of outpatient visits in a 1-year period between intervention and control group.	1 year
Secondary	Ankylosing Spondylitis Disease Activity Score (ASDAS)	ASDAS is a composite index to assess disease activity in ankylosing spondylitis. Parameters included are C-reactive protein value (mg/L) and four self-reported items (0-10, numerical rating scale [NRS]): back pain, duration of morning stiffness, peripheral pain/swelling and patient global assessment of disease activity. Higher scores on individual parameters represent more severe symptoms. Higher ASDAS represents higher disease activity.	1 year
Secondary	Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)	BASDAI consists of 6 questions representing the 5 major symptoms of ankylosing spondylitis (AS), every question is answered by using a 0-10 numerical rating scale with higher scores representing more severe symptoms: fatigue, spinal pain, joint pain / swelling, areas of localized tenderness, morning stiffness duration, morning stiffness severity. The mean of the two scores relating to morning stiffness is taken. The resulting sum of all scores (0 to 50 score) is divided by 5, resulting in a 0 - 10 BASDAI score, with increasing scores representing more active disease.	1 year
Secondary	Global well-being patient	Assesses the patient's global well-being during the last week on a Visual Analogue Scale, range: 0-100 mm. A score of 100 mm represents the worst outcome.	1 year
Secondary	Patient reported pain	Visual Analogue Scale, 0-100 mm. A score of 0 equals no pain. Higher scores represent more severe pain.	1 year
Secondary	Disease activity according to physician	Visual Analogue Scale, 0-100 mm. A score of zero equals no disease activity. Higher scores represent more active disease.	1 year
Secondary	C-Reactive Protein (CRP)	Amount of CRP detected in blood samples, expressed in mg/L.	1 year
Secondary	Tender Joint Count 66 / Swollen Joint Count 68	Only if present, the number of tender (0-66) and swollen (0-68) joints will be evaluated by an independent assessor at each physical outpatient visit.	1 year
Secondary	Presence of dactylitis and/or enthesitis	If present, dactylitis (presence/absence, locations) and enthesitis (presence/absence, locations) will be evaluated by an independent assessor at each physical outpatient visit.	1 year
Secondary	Psoriasis severity: Body Surface Area (BSA)	Measurement of total area of patient's body affected by psoriasis, expressed in percentages (range: 0 - 100).	1 year
Secondary	Psoriasis severity: Nail involvement	Nail changes due to psoriasis will be reported as either present (yes) or absent (no).	1 year
Secondary	36-item Short Form Health Survey (SF-36)	The SF-36 survey contains 36 items, covering eight domains and one single item that provides an indication of perceived change in health. Aggregate percentage scores will be calculated for two components (Mental Component Score [MCS] and Physical Component Score [PCS]). Range: 0% (worst possible level of functioning) to 100% (best possible level of functioning).	1 year
Secondary	EuroQol with 5 dimensions and 5 point Likert scale (EQ-5D-5L)	The EQ-5D-5L evaluates five dimensions, each dimension has 5 levels (no problems, slight problems, moderate problems, severe problems, extreme problems). This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. In addition, a vertical Visual Analogue Scale records the patient's self-rated health (range: 'The worst health you can imagine' [0 mm, bottom-end] to 'The best health you can imagine' [100 mm, top-end]).	1 year
Secondary	Assessment of SpondyloArthritis international Society health index (ASAS HI)	The ASAS HI contains 17 dichotomous response items (0 = 'I do not agree'; 1 = 'I agree'). A sum score is calculated, resulting in a total ASAS HI score ranging from 0 to 17. Lower scores indicate a better health status.	1 year
