The Effects of a Digital Health Intervention on Patient Activation in Chronic Kidney Disease

My Kidneys & Me (MK&M), a digital health intervention delivering specialist health and lifestyle education for people with CKD, was developed and its effects tested (SMILE-K trial, ISRCTN18314195, 18/12/2020). 420 adult patients with CKD stages 3-4 were recruited and randomised 2:1 to intervention (MK&M) (n = 280) or control (n = 140) groups. Outcomes, including Patient Activation Measure (PAM-13), were collected at baseline and 20 weeks. Complete case (CC) and per-protocol (PP) analyses were conducted. 210 (75%) participants used MK&M more than once. PAM-13 increased at 20 weeks compared to control (CC: +3.1 (95%CI: -0.2 to 6.4), P = 0.065; PP: +3.6 (95%CI: 0.2 to 7.0), P = 0.041). In those with low activation at baseline, significant between-group differences were observed (CC: +6.6 (95%CI: 1.3 to 11.9), P = 0.016; PP: +9.2 (95%CI: 4.0 to 14.6), P < 0.001) favouring MK&M group. MK&M improved patient activation in those who used the resource compared to standard care, although the overall effect was non-significant. The greatest benefits were seen in those with low activation.
