Aim: To determine the cost-effectiveness of a mobile phone text messaging intervention (KIDNEYTEXT) targeting dietary behaviours in people receiving haemodialysis.
Background: A key component of determining feasibility is to determine whether an intervention is cost-effective. There is a paucity of data available to inform the cost-effectiveness of eHealth interventions in improving patient health outcomes.
Methods: A trial-based economic evaluation from a health system perspective of a 6-month pilot randomized controlled trial (KIDNEYTEXT) was undertaken. Outcomes included the cost of the KIDNEYTEXT intervention, cost-effectiveness and marginal effects on total costs. KIDNEYTEXT trial registration – ACTRN12617001084370.
Results: The cost of developing and maintaining the KIDNEYTEXT intervention was AU$160 per participant. At 6 months the total costs were AU$2058 higher in the usual care arm compared to the intervention arm. The incremental benefits were greater than 0 for both QALYs and dietary adherence. The largest component of total costs was related to admission to hospital.
Conclusion: Mobile phone text messages targeting dietary behaviours may be cost saving, while maintaining similar or improved dietary behaviours. A larger trial with longer follow-up time is warranted.
