DIGICHOL: Effects of a Digital Health Application (Lipodia) on LDL-cholesterol Levels
Study Details
Study Description
Brief Summary
This pragmatic randomized controlled trial (RCT) with 272 patients with hypercholesterolemia aims to investigate the effectiveness of lipodia, an unguided digital health intervention for patients with hypercholesterolemia on plasma lipid levels and other clinical variables. Inclusion criteria are: age ≥ 18 years, presence of hypercholesterolemia, low-density lipoprotein cholesterol (LDL-C) levels above the risk-adapted target, stability of potential drug treatments for at least four weeks, and stability of potential hormonal treatment for at least 6 months, next to provision of informed consent and sufficient knowledge of the German language. Exclusion criteria are plans to change potential drug treatment in the upcoming 6 months, the presence of homozygous familial hypercholesterolemia (FH) or type III hyperlipidemia, receiving plasmapheresis, Lp(a) > 50 mg/dL, triglyceride (TG) above 400 mg/dL, current pregnancy, planned major operations, liver dysfunction, end-stage renal failure, and other systemic diseases that might interfere with successful study participation.
Patients will be randomized and allocated to either an intervention group, in which they will receive access to lipodia in addition to treatment as usual (TAU), or to a control group, in which they will receive only TAU.
The primary endpoint will be a change in plasma LDL-C levels, with six months post-allocation (T2) being the primary timepoint for assessment of effectiveness. Three months post-allocation (T1) will serve as early-response assessment of endpoints. Secondary endpoints will be patient activation, the change in levels of other plasma lipids (non-high-density lipoprotein cholesterol (non-HDL-C), high-density lipoprotein cholesterol (HDL), TG), responder rate of LDL-C, self-reported health-related quality of life, and BMI.

Experimental: Intervention group Participants allocated to the intervention group will receive access to lipodia in addition to treatment as usual (TAU). lipodia is a digital health application designed for individuals with hypercholesterinemia, accessible through a web browser. The application focuses on treatment methods derived health behavior change and cognitive behavioral therapy (CBT). Topics addressed by lipodia are activity planning and impulse control, dietary habits, physical activity, stress management, mood management, sleep management, weight management, as well as quitting smoking and drinking. The program operates through interactive "dialogues", which are accompanied by illustrations, audio recordings, motivating text messages, worksheets, and summaries. Users are also encouraged to regularly complete short questionnaires to monitor their complaints. Once registered, the program remains accessible for 365 days. |
