Effectiveness of the eCARE programme: a short message service for asthma monitoring.

Objective: To evaluate the effectiveness of the upgraded eCARE monitoring system on asthma control in discharged emergency department (ED) patients.

Methods: A multicentre randomised controlled study (randomised controlled trial) was done for patients with a primary diagnosis of asthma seen at the EDs in Singapore between 1 March 2013 and 28 February 2015. Those who met the inclusion criteria were randomised into a control group (routine care, n=212) and intervention group (eCARE, n=212). Patients in the intervention group received short message service (SMS) messages according to a structured workflow, while patients in the control group did not receive SMS support.

Results: For patients with poorly controlled asthma at recruitment, the results at 5 weeks showed no statistical difference in the proportion of patients who attained well-controlled asthma between the eCARE and routine care groups. At 3 months, the routine care group had a higher proportion of patients with well-controlled asthma but this was not statistically significant after adjustment for baseline differences using logistic regression. Approximately 95% of patients under the eCARE programme were satisfied with the SMS service.

Discussion: Patients in the eCARE programme did not have better asthma control than those receiving routine care. Conversely, patients in the eCARE programme appeared to have poorer asthma control, though a larger sample size will be required to confirm this finding.
