Internet-based self-management compared with usual care in adolescents with asthma: a randomized controlled trial.
BACKGROUND
Asthma control often is poor in adolescents and this causes considerable morbidity. Internet-based self-management (IBSM) improves asthma-related quality of life in adults. We hypothesized that IBSM improves asthma-related quality of life in adolescents.


METHODS
Adolescents (12-18 years) with persistent and not well-controlled asthma participated in a randomized controlled trial with 1 year follow-up and were allocated to IBSM (n = 46) or usual care (UC, n = 44). IBSM consisted of weekly asthma control monitoring with treatment advice by a web-based algorithm. Outcomes included asthma-related quality of life (Pediatric Asthma Quality of Life Questionnaire, PAQLQ) and asthma control (Asthma Control Questionnaire, ACQ) and were analyzed by a linear mixed-effects model.


RESULTS
At 3 months, PAQLQ improved with 0.40 points (95% CI: 0.17-0.62, P < 0.01), by IBSM compared to 0.0 points for UC (P = 0.02 for the difference). At 12 months the between-group difference was -0.05 (95% CI: -0.50 to 0.41, P = 0.85). At 3 months ACQ improved more in IBSM than in UC (difference: -0.32 points; 95% CI: -0.56 to -0.079, P < 0.01). At 12 months the difference was -0.05 (95% CI: -0.35 to 0.25, P = 0.75).


CONCLUSIONS
IBSM improved asthma-related quality of life and asthma control in adolescents with not well-controlled asthma after 3 months, but not after 12 months.
