COPD Clinical Trial
Official title:
Evaluation of a Mobile Application to Facilitate the Interpretation of the Spirometry Test by Family Physicians and Family Medicine Residents: Impact on Prescription and Interpretation of This Test
Problematic: Spirometry is used to objectify the obstructive syndrome defining chronic
obstructive pulmonary disease (COPD). However, this test remains underused in the primary
care. The tools available for its interpretation are little used and the existence of several
decision algorithms can create confusion during the diagnosis.
Principal objective: To evaluate the impact of a mobile application (SPIRO©) on medical
practice (interpretation and prescription of spirometry) of family physicians and family
medicine residents working in family medicine units (FMU) in Quebec affiliated with Laval
University.
Secondary objective : To evaluate the usability of SPIRO© among family physicians and
residents in family medicine working in FMU in Quebec affiliated with Laval University.
Methods: This is a pre-post clinical trial with control group. Participants (family MD and
family medicine residents) will be recruited from the various FMU affiliated with Laval
University. Participants working in the FMU in the experimental group will be able to use the
SPIRO® mobile application to facilitate interpretation of the spirometry test results while
participants in the control group will not have access to it during the study. The basic
characteristics of the participants and various behavioral parameters based on the theory of
planned behavior concerning the interpretation and prescription of spirometry test will be
measured. Data from the control group will be collected before those in the experimental
group at the time the application is not yet available, which will minimize contamination
between groups. The data will be collected with questionnaires delivered in person to the
participants before the intervention (T0 time) and then four months later (T1 time) during
their team or research meeting. Participants will be recruited in eight of the 12 Quebec FMU
affiliated with Laval University, who will be randomly assigned to two equal groups: control
and experimental. The intervention will consist in sending the SPIRO© mobile application to
participants in the experimental group who will use it for a period of four months.
Hypothesis : The investigators hypothesize that the use of the SPIRO© application will
increase the skills and confidence of family physicians and family medicine residents in
prescribing and interpreting spirometry compared to the control group.
The project will be conducted in the following six major steps: 1) Collection of
socio-demographic and behavioral characteristics of participants using sections A, B, C and D
of the NAPI questionnaire in the control group; 2) Intervention in the control group (they
will continue their daily medical practice without being subject to any intervention by our
research team), for a period of 4 months; 3) Measurement of behavioral changes in the control
group using Sections B, C, D and E of the NAPI questionnaire 4 months after the start of the
study; 4) Collection of socio-demographic and behavioral data from participants in the
experimental group using sections A, B, C and D of the NAPI questionnaire; 5) E-mail
distribution of the application and use of the application by participants in the
experimental group for a period of four months, 6) Measurement of behavioral changes in the
experimental group after the use of the application, Using sections B, C, D and E of the NAPI
questionnaire as well as a questionnaire on the application SPIRO© (SPIRO questionnaire)
which will evaluate the usability of this one.
The study has been approved by the research ethic board of the Health and Social Services
Center of the old capital - attached to the Integrated Center for Health and Social Services
of the National Capital.
