Onderzoek naar (kosten) effectiviteit van epilepsiehonden

Projectomschrijving

Het doel van dit onderzoek is het evalueren van de kosten en effecten van epilepsiehonden bij patiënten met refractaire epilepsie (epilepsie waarbij medicatie niet werkt). Epilepsiehonden zijn honden die worden getraind om op een epileptische aanval van hun baas te reageren, door bijvoorbeeld het inschakelen van hulp.

De EPISODE trial (EPIlepsy SuppOrt Dog Effectiveness trial) wordt uitgevoerd met een gerandomiseerd ‘stepped-wedge’ ontwerp. Dit betekent dat alle deelnemers aan het onderzoek (naar verwachting 35) een epilepsiehond krijgen. Het moment waarop de deelnemers een hond krijgen, is echter voor iedere deelnemer anders, en wordt aselect bepaald. Gedurende de studie wordt de gezondheid (bijvoorbeeld aanvalsfrequentie en kwaliteit van leven) en het welzijn van de deelnemers bestudeerd, zowel voor als na het krijgen van een epilepsiehond. Met de verzamelde gegevens kunnen we aan het einde van de studie aangeven wat de gezondheids-opbrengsten zijn van een epilepsiehond, en hoeveel het kost om deze opbrengsten te genereren. Deze kennis heeft Zorginstituut Nederland nodig om een advies te kunnen geven aan het ministerie van VWS over vergoeding van epilepsiehonden vanuit het basispakket.

Samenvatting van de aanvraag

OBJECTIVE(S)/RESEARCH QUESTION(S) Patients with epilepsy could have persistent seizures despite treatment with anti-epileptic drugs or epilepsy surgery. The aim of this study is to evaluate the (cost-)effectiveness of seizure dogs compared to standard care in patients with refractory epilepsy. HYPOTHESIS With the introduction of a seizure dog, we expect that the number of epileptic seizures decreases. Besides the effect of seizure dogs on seizure frequency, we expect an impact on other outcomes measures, such as well-being and health-related quality of life. Furthermore, we expect seizure dogs to decrease the seizure severity, lower the burden on informal caregivers and reduce healthcare resource use. STUDY POPULATION(S)/DATASETS The study population consists of patients with refractory epilepsy (i.e. medication resistant epilepsy) who are not eligible for epilepsy surgery and have a high risk of injury or dysfunction. INTERVENTION The intervention consists of seizure dogs. The training of these dogs focuses on responding to seizures during or immediately after an epileptic seizure occurs in their human companion. Seizure dogs may also be able to develop alerting behaviour, which consist of anticipating on an impending seizure event and providing a warning signal to the human companion (before the seizure). USUAL CARE /COMPARISON Since there are no alternative treatment options available for patients with refractory epilepsy who are not eligible for epilepsy surgery, standard care consists of ‘doing nothing’. OUTCOME MEASURES The primary outcome of the study will be seizure frequency. Besides this outcome measure, the impact of seizure dogs on seizure severity, well-being, health-related quality of life and healthcare resource use will be evaluated. STUDY DESIGN We plan to evaluate the (cost-)effectiveness of seizure dogs with a stepped-wedge (or randomised-delay) design, which uses observations at multiple time points both before and after the intervention. This implies that we have for each subject a time series of measurements for each of the outcomes of interest. There is no separate control group; patients act as their own controls. We will start including patients at the end of the second quarter of 2018. DATA COLLECTION AND ANALYSIS Seizures will be recorded continuously using a seizure diary. Data regarding health-related quality of life will be collected using the EQ-5D and the QOLIE 31. The ICECAP will be used to measure the well-being of patients with epilepsy. Furthermore, the iMCQ (iMTA Medical Consumption Questionnaire), the iVICQ (iMTA Valuation of Informal Care Questionnaire) and the iPCQ (iMTA Productivity Cost Questionnaire) will be used to collect data regarding health care use, informal care and productivity losses. A simple before-and-after comparison will be conducted, by calculating per person the average of the measurements before the dog’s training starts, during the dog’s epilepsy training at home and after the training of the dog is completed, using repeated measures anova. Additionally, mixed effect models for repeated measurements will be used, with random patient effects and slopes. SAMPLE SIZE CALCULATION Within the total budget of €857,709, Stichting Hulphond Nederland and Bultersmekke can train a total of 35 dogs. With 35 patients (and dogs), we should be able to detect a significant difference in the number of seizures. COST-EFFECTIVENESS ANALYSIS/ BUDGET IMPACT ANALYSIS The cost-effectiveness analysis will adopt a societal perspective in line with the Dutch guidelines for economic evaluations in healthcare. The most important cost category within the cost-effectiveness analysis is the cost of training seizure dogs. Besides the costs of the intervention, costs within the healthcare sector will be incorporated, just as patient and family costs (i.e. time costs) and costs in other sectors (i.e. productivity costs). The cost-effectiveness study ultimately leads to an incremental cost per QALY gained. Besides the cost-effectiveness analysis, a budget impact analysis will be conducted, taking into account the size and characteristics of the affected population, the current intervention mix and the new intervention mix. TIME SCHEDULE In three years (2018-2020), Stichting Hulphond Nederland and Bultersmekke will be able to train and match 35 seizure dogs. Data analyses and reporting will be conducted in 2021.
