Smartphone-App as Maintenance Program in COPD (AMOPUR)

Impact of a Smartphone Application (KAIA COPD-App) in Combination With Activity Monitoring as Maintenance Program Following Pulmonary Rehabilitation in COPD: an International Multi-centered Randomized Controlled Trial

Increasing Physical activity (PA) is considered to be an important factor in an efficient management of the chronic obstructive pulmonary disease (COPD). The successful methods required to achieve improvements in PA following Pulmonary Rehabilitation (PR), however are sparsely reported. Therefore, the investigators conduct this trial to evaluate the effectiveness of using a COPD management program delivered to the patient through a mobile medical application Kaia COPD-App, after the completion of a PR.

Study Overview

• Status: Completed
• Conditions: Pulmonary Disease, Chronic Obstructive
• Intervention / Treatment: Device: Kaia COPD Application; Other: Usual Care

Detailed Description

This is a randomized, controlled, open-label, multi-centered trial carried out at in-patient PR-hospital centers in Germany and Switzerland . The interventions will involve use of KAIA COPD-app program (Arm 1) or an active comparator i.e. usual care (Arm 2). Patients completing an in-hospital PR-Program and consenting to participate in the study will be screened for the inclusion and exclusion criteria and enrolled in the study. After fulfillment of the screening requirements, they will be randomized into one of the two arms with parallel group assignment in a 1:1 ratio. The training program will be delivered to the participants grouped to the arm 1 through KAIA COPD-App and arm 2 as provided in regular recommendations or standard of care through the PI. In total, 104 participants will be included to the trial. Treatment period will last for 24 weeks. Electronic versions of Questionnaires will be used to collect patient reported assessments remotely. The primary outcome measure is the change in physical activity of the intervention group in comparison to the control group, measured over one week as mean steps per day with the Polar A 370 activity tracker, from baseline (end of PR) to 6-months follow-up. The secondary outcome measures are functional exercise capacity, health status, sleep quality, exacerbation rate, depression and anxiety symptoms assessed at several intervals.

This study seeks to prove the implications of the Kaia COPD mobile application in COPD patients after PR. The app offers educational, exercise training plus activity monitoring and motivational program that can be easily implemented in the patient's home-setting enabling patients.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Device: KAIA COPD-App (Medical Mobile Application).; The study intervention is an exercise training program that requires only a chair or water bottles, consisting of training elements with progressive levels of intensity, individually adaptable to the participant's exercise level. This training program is delivered to the participants with the help of KAIA COPD-App. Additionally, the Polar A370 watch will collect the daily symptoms and training log during each session for the Database.	Device: Kaia COPD Application; The study intervention consists of training sessions conducted daily by the patient via the COPD-App.
Active Comparator: Usual Care; The Training of the control-group is performed by regular recommendations/ Standard of care. Standard of care in this context means to hand out the brochure " Besser Leben mit COPD " including an emergency plan, providing exercise training examples, to hand out addresses of out-patient physiotherapists and to hand out a detailed medical report including medical recommendations.Additionally, the Polar A370 watch will collect the daily symptoms and training log during each session for the Database.	Other: Usual Care; The control group will also be an active control as participants receive a leaflet to convey an active lifestyle and a list of exercises to do at home.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Steps per day as mean over one week from baseline until the treatment end	The primary outcome are the steps per day as mean over one week from baseline (second week after discharge from PR) to 6 months follow-up in the intervention group in comparison to the control group as an equivalent for the physical activity of the participants, measured by an activity tracker (Polar A370-Watch).	Every day for 6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Dyspnea	Dyspnea will be assessed by the COPD Assessment Test (CAT) which measures the impact of COPD on a person's health status (8 questions, 6-point Likert-type scale)	Baseline, Visit 5 (12 weeks) and Visit 8( 24 weeks)
Functional exercise capacity using I min Sit to stand test	Functional exercise capacity will be assessed by the widely-used and validated 1-min sit-to-stand test (STS). The patients are guided through an integrated video with a stop watch in an ePRO to perform the test in a right way in home settings.	Baseline (day 0), Visit 5 (12 weeks) and Visit 8( 24 weeks)
Quality of life through SAS-CRQ	SAS- CRQ The chronic respiratory questionnaire, a self-administered instrument, includes 20 items across four domains: dyspnea (5 items), fatigue (4 items), emotional function (7 items), and mastery (4 items). Patients will be scored for the Quality of life around their experience on a 7-point scale ranging from 1 (maximum impairment) to 7 (no impairment).	Baseline (day 0), Visit 5 (12 weeks) and Visit 8( 24 weeks)
Subjective health status	A feeling thermometer scale allows respondents to rank how positively individuals feels about the quality of life to measure individuals' subjective health status. The scale ranges from a minimum of 0 to a maximum of 100.	At the Baseline (Day 0) and every 4 weeks (V2 to V8) until the end of treatment period of 24 weeks
Sleep efficacy and total sleep time	Sleep efficacy (SE) and total sleep time (TST)will be measured by the Polar A370 Watch every night during the treatment period.	Every night for 6 months of treatment period
Motivation for reaching his or her individual defined goal of physical activity	This assessment is linked to the intervention group using COPD App only. During monthly visits, a certain number of steps will be fixed as a goal for the patients in the COPD application.	At the Baseline (Day 0) and every 4 weeks (V2 to V8) until the end of treatment period of 24 weeks
Assessment of usability	This assessment is linked to the intervention group using COPD App only. The use of the application will be assessed every week through patient data reports captured in the COPD Application.	End of the treatment period of 24 weeks from baseline
Rate, number and severity of adverse events	The AEs and SAEs will be documented to assess the safety related to the use of the application and trainings, in the home settings.	At baseline (day 0) and every 2 weeks after, until the end of the treatment period of 24 weeks
Rate, number and severity of device deficiencies	The DDs will be documented to assess the performance of the device and usability.	At baseline(day 0) and every 2 weeks after, until the end of the treatment period of 24 weeks
Hospital Anxiety and Depression Scale	The HADS Questionnaire will be used to measure anxiety and depression. Each item on the questionnaire is scored from 0-3 and this means that a person can score between 0 and 21 for either anxiety or depression.	Baseline (day 0), Visit 5 (12 weeks) and Visit 8( 24 weeks)
