Eur J Prev CardiolPublished

  • Randomised controlled trial
  • assessor-blinded
  • two-arm
  • two regional hospitals in Hong Kong

Authors' conclusion

Remotely delivered i-CARE intervention effectively promote self-care among CAD patients and may help address critical healthcare workforce shortages, while also conferring secondary benefits in blood pressure and HRQoL.

Primary result

As reported in the abstract

Self-care behaviours
self-care maintenance
β 4.055 (95% CI 1.420–6.691); P = 0.003
self-care confidence
β 5.609 (95% CI 1.089–10.129); P = 0.015

Secondary outcomes

BP and health-related quality of life (HRQoL) · 3 months

SBP reduction with the intervention, β (95% CI), P
−3.725 (−7.322 to −0.128), P = 0.042
DBP reduction with the intervention, β (95% CI), P
−2.153 (−4.228 to −0.079), P = 0.042
HRQoL improvement with the intervention, β (95% CI), P
0.208 (0.073-0.343), P = 0.003
  • benefits for DBP and HRQoL sustained at 6 months
