Improving clinical data collection in the patients’ home in Parkinson’s disease: the SleepFit app (Preprint)
BACKGROUND Home-based systems for ecological momentary assessment of clinically-relevant information in Parkinson’s Disease (PD) are helpful tools to improve patients’ care. Nevertheless, new technologies are not always easy-to-use for these patients. OBJECTIVE We developed a tablet-based application, SleepFit, specifically designed for patients with PD, to collect objective and subjective data at their home. SleepFit is presented with the improvements made from the prototype to the latest v2.0 version, aimed to enhance user-friendliness and the quality of the collected data. METHODS The core structure of SleepFit consists of: a) an electronic finger-tapping test; b) motor, sleepiness, and emotional subjective scales; c) a sleep diary. SleepFit v2.0 features enhanced ergonomics and graphics; automated flows that guide the patients in performing tasks throughout the 24 hours; secured real-time data collection and consultation; the possibility to easily integrate new tasks and features. Fifty-six patients with PD were asked to perform multiple home-assessments four times a day for two weeks. Patients’ compliance to SleepFit was calculated as the proportion of completed tasks out of the total number of expected tasks; satisfaction was evaluated as a potential willingness to use SleepFit again after the end of the study. RESULTS Fifty-two patients were included in the analyses. Overall compliance (all versions) was 88.9%. SleepFit was progressively enhanced and compliance increased from 87.9% to 89.9%. Among the patients who used the final version, 96.2% declared they would use SleepFit again. CONCLUSIONS SleepFit is an easy-to-use tablet-application to prospectively collect objective and subjective clinical data and to increase compliance in home-based studies in PD
