NCT07262229

Brief Summary

The goal of this pilot randomized controlled trial is to evaluate the feasibility, acceptability, and preliminary effects of a theory-based self-management digital intervention (Respir'air BPCO) designed to promote physical activity in patients with Chronic Obstructive Pulmonary Disease (COPD) after completion of a pulmonary rehabilitation program. The main question it aims to answer is: Is the Respir'air BPCO intervention (mobile app) feasible, acceptable, and preliminarily effective in increasing physical activity, enhancing self-management, improving motivation, and quality of life, while reducing dyspnea severity, exacerbations, and hospitalizations, compared with no additional intervention? Researchers will compare an experimental group (receiving the Respir'air BPCO intervention + usual care) to a control group (no additional intervention, only usual care) Participants will: Be assigned either to the control group, receiving no additional intervention beyond usual care (traditional pulmonologist follow-up), or to the experimental group, receiving access to the Respir'air BPCO mobile app in addition to usual care.

  • Complete baseline assessments immediately after finishing their in-person pulmonary rehabilitation program.
  • Complete follow-up assessments at 3 months and 6 months after the start of the intervention

Outcome Measures

Primary Outcomes (10)

  • Trial methodological feasibility indicator - Time required to complete recruitment

    T0 - End of face-to-face PR program (Researchers expect to need 3 months to recruit 20 participants.)

  • Trial methodological feasibility indicator - Consent rate

    Consent rate: proportion of eligible participants who sign the informed consent form

    T0: Within 72 hours after completion of the face-to-face PR program

  • Intervention feasibility indicator - Potential refinements after the completion of the pilot study

    A digital logbook for researchers' use, to record any observations or comments (patients and/or researchers perspectives) regarding the intervention design, content and/or usage, with the aim of informing potential refinements after the completion of the pilot study

    From the start of the intervention to study completion, assessed for up to 9 months.

  • Intervention acceptability indicators - App usage

    Daily App Login Status

    T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

  • Intervention acceptability indicators - Intervention acceptance

    French-adapted version of the Treatment Acceptance and Preference (TAP) questionnaire.Responses are scored on a five-point Likert scale ranging from 0 ("not at all") to 4 ("extremely"), with higher scores reflecting greater acceptance.

    T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

Secondary Outcomes (7)

  • Preliminary effectiveness measures - Main variable: number of daily steps

    T0: Within 72 hours after completion of the face-to-face PR program T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

  • Preliminary effectiveness measures - secondary variable: Self-management

    T0: Within 72 hours after completion of the face-to-face PR program T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

  • Preliminary effectiveness measures - secondary variable: Motivational regulation of physical activity

    T0: Within 72 hours after completion of the face-to-face PR program T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

Data Sharing

IPD Sharing
Will share

De-identified individual participant data (IPD) underlying the results reported in publications, including demographic characteristics, outcome measures, and study variables necessary to reproduce the analyses, will be made available upon reasonable request to the Principal Investigator. Given the relatively small sample size and the detailed clinical information collected in this single-centre study, full anonymization in the legal sense (i.e., irreversible de-identification with no reasonable means of re-identification) may not be achievable for all variables. A disclosure risk assessment will therefore be conducted once data collection is complete, to determine an appropriate level of data granularity. Depending on the outcome of this assessment, high-risk quasi-identifiers (e.g., precise age, detailed geographic or clinical subgroup information) may be generalized, aggregated, or withheld, and data will be shared through a secure transfer platform.

Shared Documents
STUDY PROTOCOL, ANALYTIC CODE
Time Frame
Data and supporting documents will be made available beginning 6 months after publication of the primary study results and will remain available for 5 years thereafter. Recipients will be required to securely destroy all shared at the end of the approved project.
Access Criteria
Access will be granted to qualified researchers whose proposed use of the data has been approved following review by the Principal Investigator (or, in the event of the PI's unavailability, a designated institutional data steward) and is consistent with the participants' informed consent, the original ethical approval, and applicable Swiss and, where relevant, other data protection regulations. Requests must include a methodologically sound research proposal and will be evaluated for consistency with the scope of participant consent. Data will be shared as de-identified datasets after execution of a Data Sharing Agreement (DSA). The DSA will require the recipient to: (a) not attempt to re-identify participants; (b) not redistribute the data to third parties; (c) store and process the data under specified security standards; and (d) destroy the data at the end of the agreed period.
