[The DISC tool improves communication and results in pulmonary rehabilitation].

Introduction. - Competence in personal relationships is essential for a caregiver, especially in pulmonary rehabilitation (PR). Considering the behavioral profile of patients might help to optimize their management and the results of PR. Methods. - We evaluated eight hundred and thirty-two consecutive patients with chronic respiratory disease who received eight weeks of home-based PR. Their exercise tolerance (six-minute stepper test, 6MST), mood (HAD), and quality of life (VSRQ, MRF28) were evaluated at the beginning and end of PR. For six hundred and ninety patients, a behavioral approach was implemented at the beginning of PR by using the DISC tool to identify four behavioral profiles: dominance, influence, steadiness, conscientiousness. The remaining 142 patients served as the control group. Results. - Subjectively, the therapeutic alliance was more easily established with the behavioral approach. Compared with the control group, patients with the "steadiness" profile were younger (60.7 +/- 12 years) and mostly female (52.8%), whereas patients with the "conscientiousness" profile were older (67.5 +/- 10.6 years) and mostly male (85.5%). The four behaviorally profiled groups showed no differences in exercise tolerance, mood, or quality of life scores at baseline. Globally, all patients improved their exercise tolerance, mood and quality of life. The percentage of responders to 6MST and VSRQ (> MCID) was 7.5% and 5.3% higher with the behavioral approach. For non-responders to 6MST and VSRQ (< MCID), only patients benefiting from the behavioral approach improved the other parameters studied, patients from control group having exhibited no improvement at all. Conclusions. - The DISC-guided behavioral approach improves the patient caregiver relationship and achieves better results at the end of PR. (C) 2018 SPLF. Published by Elsevier Masson SAS.
