Objective: To analyze the opinion of different neurologists from Spain about the STAT-ON tool after using the device in a real clinical practice setting (RCPS).

Background: The identification of motor fluctuations in Parkinson´s disease (PD) patients is important for PD treatment but not straightforward. STAT-ON is an objective tool that registers ON-OFF fluctuations making possible to know the state of the patient for a week (1,2).

Methods: CE Mark Medical Device STAT-ON was provided by the Company Sense4Care to Spanish neurologists for using it in a RCPS. All neurologists were expert on PD. Each neurologist had the device for at least 3 months and could use it in PD patients at his/her own discretion. In February 2020, a survey with 30 questions was sent to all participants. The data was anonymized and 3 waves were made to obtain the responses.

Results: A total of 27 surveys were received (51.9% females; mean age 44.9 ± 9 years old). Two thirds of the neurologists worked in a Movement Disorders Unit, the mean experience on PD was of 16 ± 6.9 years, and 59.3% of them had used previous different devices for PD. A total of 119 evaluations in 114 patients (range from 2 to 9 per neurologist; mean 4.5 ± 2.3) were performed. Using a score from 1 (unhelpful) to 7 (very helpful), the opinion about different usability aspects was recorded (Table 1). The subjective general opinion about the device (from 0, the worst, to 10, the best) was 6.9 ± 1.7. STAT-ON was considered better than the diaries by 70.3% of the neurologists (Figure 1A) and a useful tool for identification of advanced PD patients by 81.5%. A high percentage of PD patients were considered that could benefit from using STAT-ON (Figure 1B). STAT-ON was considered from quite to very useful by 74% of the neurologists (Figure 1C). A correlation was observed between the number of assessments performed and the opinion about the device (r=0.403; p=0.046). Proper identification of FOG episodes and falls were the most frequent limitations reported.

Conclusions: STAT-ON could be a useful device for using in PD patients in clinical practice.
