Development, usability and acceptability of an integrated eHealth system for spondyloarthritis in the Netherlands (SpA-Net).

Objective: To develop and test the usability and acceptability of a disease-specific integrated electronic health (eHealth) system for spondyloarthritis (SpA) in the Netherlands ('SpA-Net'). Methods: SpA-Net was developed in four phases. First, content and design were discussed with experts on SpA and patients. Second, the database, electronic medical record (EMR) and quality management system were developed. Third, multiple rounds of testing were performed. Fourth, the eHealth system was implemented in practice and feasibility was tested among patients through semistructured focus interviews (n=16 patients) and among care providers through feedback meetings (n=11 rheumatologists/fellows and 5 nurses). Results: After completion of the first three steps of development in 2015, SpA-Net was implemented in 2016. All patients included have a clinical diagnosis of SpA. Information on domains relevant to clinical record-keeping is prospectively collected at routine outpatient consultations and readily available to care providers, presented in a clear dashboard. Patients complete online questionnaires prior to outpatient visits. In February 2019, 1069 patients were enrolled (mean [SD] age 54.9 [14.1] years, 52.4% men). Patients interviewed (n=16) considered SpA-Net an accessible system that was beneficial to disease insight and patient-physician communication, and had additional value to current care. Care providers appreciated the additional information for (preparing) consultations. Barriers were the initial time required to adopt the EMR and the quantity of data entry. Conclusion: SpA-Net enables monitoring of patients with SpA and real-life data collection, and could help improve knowledge and optimise communication between patients and care providers. Both considered SpA-Net a valuable addition to current care. Trial registration number: NTR6740.

Cost effectiveness of combined spa-exercise therapy in ankylosing spondylitis: a randomized controlled trial.

OBJECTIVE: To evaluate the cost effectiveness and cost utility of a 3-week course of combined spa therapy and exercise therapy in addition to standard treatment consisting of antiinflammatory drugs and weekly group physical therapy in ankylosing spondylitis (AS) patients. METHODS: A total of 120 Dutch outpatients with AS were randomly allocated into 3 groups of 40 patients each. Group 1 was treated in a spa resort in Bad Hofgastein, Austria; group 2 in a spa resort in Arcen, The Netherlands. The control group stayed at home and continued their usual activities and standard treatment during the intervention weeks. After the intervention, all patients followed weekly group physical therapy. The total study period was 40 weeks. Effectiveness of the intervention was assessed by functional ability using the Bath Ankylosing Spondylitis Function Index (BASFI). Utilities were measured with the EuroQoL (EQ-5D(utility)). A time-integrated summary score defined the clinical effects (BASFI-area under the curve [AUC]) and utilities (EQ-5D(utility)-AUC) over time. Both direct (health care and non-health care) and indirect costs were included. Resource utilization and absence from work were registered weekly by the patients in a diary. All costs were calculated from a societal perspective. RESULTS: A total of 111 patients completed the diary. The between-group difference for the BASFI-AUC was 1.0 (95% confidence interval [95% CI] 0.4-1.6; P = 0.001) for group 1 versus controls, and 0.6 (95% CI 0.1-1.1; P = 0.020) for group 2 versus controls. The between-group difference for EQ-5D(utility)-AUC was 0.17 (95% CI 0.09-0.25; P < 0.001) for group 1 versus controls, and 0.08 (95% CI 0.00-0.15; P = 0.04) for group 2 versus controls. The mean total costs per patient (including costs for spa therapy) in Euros (euro;) during the study period were euro;3,023 for group 1, euro;3,240 for group 2, and euro;1,754 for the control group. The incremental cost-effectiveness ratio per unit effect gained in functional ability (0-10 scale) was euro;1,269 (95% CI 497-3,316) for group 1, and euro;2,477 (95% CI 601-12,098) for group 2. The costs per quality-adjusted life year gained were euro;7,465 (95% CI 3,294-14,686) for group 1, and euro;18,575 (95% CI 3,678-114,257) for group 2. CONCLUSION: Combined spa-exercise therapy besides standard treatment with drugs and weekly group physical therapy is more effective and shows favorable cost-effectiveness and cost-utility ratios compared with standard treatment alone in patients with AS.
