Registration Number

Lead Sponsor
University Hospital, Montpellier
Brief Summary

The onset of smartphone usage has provided new opportunities for managing patients outside the walls of healthcare facilities. The development of asthma-specific smartphone applications represents an excellent area for partnership between developers and medical teams for delivering therapeutic education at the required time and in a personalised way. Within this context, the overall goal of the AsthmaTrain study is to perform a first, small pilot study comparing a new French-language chat-bot guided asthma patient education programme (the 'Vik' application) with the classic, authority-approved patient education program at the University Hospitals of Montpellier, Montpellier, France.

The primary objective is to compare a population of adult patients with asthma and participating in a standard patient education programme with a similar population participating in Vik-guided education programme in terms of change in overall scores on the Asthma Quality of Life Questionnaire (AQLQ).

Detailed Description

Secondarily, the following will also be compared between the two study arms:

* the subdomains of the AQLQ score,

* lung function, overall asthma control and exacerbation rates,

* general health status via the Euroqol 5-domain 5-level questionnaire (EQ-5D-5L),

* adherence to the program and burden of the program for the medical team,

* major categories of direct health resource consumption.

Finally, because education intervention success may depend on patient-specific characteristics, an ancillary study will compare the following baseline traits between the 50% best intervention responders in either arm:

* the big five personality traits,

* the hospital anxiety and depression,

* coping mechanisms.

Primary Outcome Measures
NameTimeMethod
Change in the total AQLQ scorebaseline to 6 months

The Asthma Quality of Life Questionnaire (AQLQ) is a 32-item, 4-domain instrument that can either be self- or interviewer-administered. The recall-time is two weeks. The four domains covered are: (i) symptoms (11 items), (ii) activity limitation (12 items, 5 of which are individualized), (iii) emotional function (5 items), and (iv) environmental exposure (4 items). Each item is ranked by the patient using a 7-point Likert scale ranging from 1 (severely impaired) to 7 (not impaired at all). Scores range from 1 to 7, higher scores indicate better quality of life and a minimally important difference (for overall scores and for each sub-domain) has been established at 0.5.

Change in the EQ-5D-5L scorebaseline to 6 months

In its original version, this self-administered questionnaire consists of two pages: the first contains the EQ-5D descriptive system and the second a visual analogue scale. The descriptive system has five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), each described by five levels of intensity ("no problems", "slight problems", "moderate problems", "severe problems" and "extreme problems or complete inability"). The respondent must indicate one intensity level for each dimension.

Accumulating numbers of specialist consultsbaseline to 6 months
Accumulating numbers of unexpected/emergency consultsbaseline to 6 months
Accumulating numbers of days of exacerbationbaseline to 6 months
Change in the ACQ-5 scorebaseline to 6 months

The ACQ-5 is a shortened version of the ACQ that assesses asthma symptoms (night-time waking, symptoms on waking, activity limitation, shortness of breath, wheezing) omitting the forced expiratory volume in 1 second measurement and short acting beta antagonist use from the original ACQ score. Patients are asked to recall how their asthma has been during the previous week by responding to 5 symptom questions. Questions are weighted equally and scored from 0 (totally controlled) to 6 (severely uncontrolled). The mean ACQ-5 score is the mean of the responses. Mean scores of ≤0.75 indicate well-controlled asthma, scores between 0.75 and \<1.5 indicate partly controlled asthma, and a score ≥1.5 indicates not well controlled asthma . Individual changes of at least 0.5 are considered to be clinically meaningful.
