Trial Outcomes & Findings for Sensor and Electronic Health Records (EHR) Integration Pilot Study (NCT NCT03357341)

NCT ID: NCT03357341

Last Updated: 2020-11-24

Results Overview

FEV1 is an important measure of pulmonary function and is the maximum amount of air that can be forced out in one second after taking a deep breath. FEV1 was measured using spirometry. Participants were given a hand-held spirometer with instructions on its proper use. Baseline (Week 1) measurement was taken in clinic and the participants were instructed to perform home spirometry on a weekly basis for the remainder of the study. The spirometry use was linked to the Propeller Health application on the iPad, which provided visual cues for the spirometry and sent the data to the central database after completion of the session. Change from Baseline was calculated as the value at specified time point minus Baseline value. Change from Baseline in FEV1 at 4-weekly intervals is presented.

Participant Flow

This was a prospective observational study that included two cohorts of participants identified through electronic health records (EHR) within the Geisinger Health System (GHS) database. The study was conducted at a single center in the United States.

A total of 194 participants were enrolled and followed up for six months. The study data was captured remotely via sensors and devices provided by GlaxoSmithKline (GSK) to the participants, or via extraction of EHR data.

Asthma Cohort
Asthma participants were identified via EHR database analyses, study provider referral (asthma diagnoses with and without specialist confirmation) or recruited from sites of usual care. Participants attended two visits at the Baseline (Visit 1) and approximately six months later (Visit 2). At Visit 2, the participants returned the study devices and attended exit interview to provide relevant feedback.
COPD Cohort
Participants with chronic obstructive pulmonary disease (COPD) were identified via EHR database analyses, study provider referral (COPD diagnoses with and without specialist confirmation) or recruited from sites of usual care. Participants attended two visits at the Baseline (Visit 1) and approximately six months later (Visit 2). At Visit 2, the participants returned the study devices and attended exit interview to provide relevant feedback.

The PROactive tool is used to investigate dimensions of physical activity (symptoms, distress, difficulties, amount etc.) that are judged as being essential by participants living with COPD. The clinic visit version of PRO was used, and was offered via the participant's electronic PRO application every 28 days. This version of PRO includes 14 items, measuring a physical activity 'Total Score' with 2 domains ('amount' and 'difficulty'). The 'amount' domain is covered by 2 items (amount of walking outside and chores outside) and by 2 activity monitor outputs (vector magnitude units per minute \[VMU/min\] and steps per day). The 'difficulty' domain is covered by 10 items. Each domain score is based on the simple addition of items (scale ranging from 0 to 15 for amount domain and 0 to 40 for difficulty domain), and then scaled from 0 to 100. 'Total Score' is calculated as the sum of the two domains (amount and difficulty) divided by two, thus scored from 0 (worse) to 100 (much better).

The E-RS: COPD scale is a derivative instrument used to measure the effect of treatment on the severity of respiratory symptoms in stable COPD. The E-RS utilizes the 11 respiratory symptom items contained in the 14-item Exacerbations of Chronic pulmonary disease Tool (EXACT). For the COPD cohort specifically, the daily EXACT was offered each evening. The domains included: respiratory symptoms (RS)-breathlessness (RS-BRL comprised of 5 items, score range \[0-17\]), RS-cough and sputum (RS-CSP comprised of 3 items, score range \[0-11\]), and RS-chest symptoms (RS-CSY comprised of 3 items, score range \[0-12\]). The total score was derived by summing the 11-item scores and ranged between 0-40 with higher values indicating severe respiratory symptoms. Scores for the week were summarized for each COPD participant where they completed the questionnaire on three or more days during the study week

PRIMARY outcome

Timeframe: Baseline (Week 1) and Weeks 5, 9, 13, 17, 21 and 25

Population: All Enrolled Population. A total of 92 participants were included in the analysis; however, only those participants with data available at the specified time points were analyzed (indicated by n=X in category titles).

The CAT is an 8 item questionnaire (cough, sputum, chest tightness, breathlessness, going up hills/stairs, activity limitation at home, confidence leaving the home, and sleep and energy) that measures health status of participants with COPD. Participants completed each question by rating their experience on a 6 point scale ranging from 0 (maximum impairment) to 5 (no impairment). Total score was calculated by summing the non-missing scores on the eight items and ranged from 0-40. Higher scores indicated greater disease impact. Week 1 was considered as Baseline. Change from Baseline was calculated as value at the specified time point minus Baseline value.

Population: All Enrolled Population. A total of 95 participants were included in the analysis; however, only those participants with data available at the specified time points were analyzed (indicated by n=X in category titles).

The ACT is a validated self-administered questionnaire utilizing 5 questions to assess asthma control on a 5-point categorical scale (1 to 5). Total score was calculated as the sum of scores from 5 questions and ranged from 5 to 25. Higher scores indicated better control of asthma. Week 1 was considered as Baseline. Change from Baseline was calculated as value at the specified time point minus Baseline value.
