Video quality using outpatient smartphone videos in epilepsy: Results from the OSmartViE study

European Journal of Neurology JANUARY 2021

RESULTS:

Forty‐four patients (31 women, age 45.1 years [r = 20–82]) were included and 530 SVs were viewed by a mean of seven experts and six residents; one video per patient was reviewed for a mean of 133.8 s (r = 9–543).
In all, 30 patients had PNEAs, 11 had ESs, and three had PhysNEEs.
Quality was suitable in 70.8% of SVs (375/530 total views), with 36/44 (81.8%) patient SVs rated as adequate by the majority of reviewers.
Accuracy improved with the presence of convulsive features from 72.4% to 98.2% in ESs and from 71.1% to 95.7% in PNEAs.
An accurate diagnosis was given by all reviewers (100%) in 11/44 SVs (all PNEAs).
Audio was rated as good by 86.2% of reviewers for these SVs compared with 75.4% for the remaining SVs (p = 0.01).
Lighting was better in SVs associated with high accuracy (p = 0.06), but clarity was not (p = 0.59).
Poor video quality yielded unknown diagnoses in 24.2% of the SVs reviewed.
Features hindering diagnosis were limited interactivity, restricted field of view and short video duration.

ASSESSMENT OF THE PREDICTIVE VALUE OF OUTPATIENT SMARTPHONE VIDEOS FOR DIAGNOSIS OF EPILEPTIC SEIZURES

JAMA NEUROLOGY JANUARY 2020

RESULTS:

The odds of receiving a correct diagnosis were 5.45 times greater using smartphone video alongside patient history and physical examination results than with history and physical examination alone (95% CI, 1.01-54.3; P = .02)
One-fourth of the smartphone videos were correctly diagnosed by 100% of the reviewing physicians, composed solely of psychogenic attacks.
When histories and physical examination results were combined with smartphone videos, correct diagnoses rose from 78.6% to 95.2%.

Outpatient Smartphone Videos for Classifying Epileptic and Nonepileptic Seizures

PRESENTED AT AMERICAN EPILEPSY SOCIETY MEETING 2017

CONCLUSION: Secure uploading, exchange, and analysis of SV data in patients with paroxysmal neurological events is feasible. Most SVs were non-convulsive though those with the highest concordance among raters were PNES almost exclusively differing from H & P. The median duration of SV was 1min 28sec vs 60 mins with routine H & P and 2.54 days with VEM (p= < 0.0001).

Outpatient Smartphone Videos in Epilepsy (OSmartViE): Initial Results of Video Quality

POSTER PRESENTED AT AMERICAN EPILEPSY SOCIETY MEETING DEC 2017

CONCLUSION: Smartphone Video (SV) are highly specific for ES diagnosis and highly sensitive to PNEA diagnosis. Most SV were adequate in clarity, audio and light according to physician review. SV were mostly limited by limited bystander interaction, lack of whole body view and ictal period recorded.

Outpatient Smartphone Videos in Epilepsy (OSmartViE): Initial Results

POSTER PRESENTED AT AMERICAN EPILEPSY SOCIETY DEC 2016

CONCLUSION: Secure exchange of Smartphone Video (SV) information is feasible. Most SV had convulsive episodes but 70% were not ES. SV diagnosis had a level of confidence similar to History & Physical. Epileptologists (71.4% accurate sv diagnostic rate) were better in identifying ES than trainees and more confident in non-epilepsy despite similar accuracy.

TESTING feasibility and utility of remote data capture technology to assess parkinson’s disease

POSTER PRESENTED AT INTERNATIONAL PARKINSON AND MOVEMENT DISORDER SOCIETY BERLIN, GERMANY JUNE 2016

CONCLUSION:

High quality of home video recordings for asynchronous video-recordings are feasible in early to mid-stage PD using a HIPAA-compliant app and cloud-based platform
Ratings from the modified “svUPDRS” are in good agreement with scores on equivalent items from the in- person UPDRS
Two independent raters did not differ significantly in ratings on the video-based visits
1 hour in-office training is adequate for most patients
Asynchronous virtual visits are a novel tool for creating an archive of rich patient data beyond the scope & scale of what can be captured in a clinical setting

REMOTE ASYNCHRONOUS TELEREHABILITATION FOLLOWING TOTAL KNEE ARTHROPLASTY

JOURNAL OF TELEMEDICINE TELECARE MARCH 2016

CONCLUSION: Overall utilization of hospital-based resources was 60% less than for the traditional group. We report that clinical outcomes following asynchronous telerehabilitation administered over the web and through a hand-held device were not inferior to those achieved with traditional care. Outpatient resource utilization was lower. Patient satisfaction was high for both groups. The results suggest that asynchronous telerehabilitation may be a more practical alternative to real-time video visits and are clinically equivalent to the in-person care model.

BENEFITS OF MEDICAL MEDIA IN PEDIATRIC NEUROLOGY

AWARDED “ORAL PRESENTATION” AT AAN POSTER SESSION APRIL 2013

CONCLUSION: CaptureProof EASY-TO-USE, NON-INVASIVE, SECURE SYSTEM FOR REAL-LIFE PATIENT MONITORING AT A FRACTION OF THE COST OF CURRENT STANDARDS WILL BENEFIT PATIENTS FROM THE VERY FIRST EVENT THROUGH DIAGNOSIS AND TREATMENT. THE STUDY DEMONSTRATED THE USEFULNESS OF MEDIA IN PEDIATRIC NEUROLOGY PRACTICES PROVING THAT IT: A) ALLOWS FOR FASTER AND MORE ACCURATE DIAGNOSIS, B) REDUCES THE NEED FOR COSTLY TESTS, ER/OFFICE VISISTS, AND LENGTHY HOSPITAL STAYS, C) OPTIMIZES TREATMENT MODALITIES AND D) RESULTS IN BETTER CARE AT A FRACTION OF THE COST OF THE CURRENT STANDARD OF CARE FOR PATIENTS.
