Insights
A guided internet-based therapy did not reduce depressive symptoms in hemodialysis patients compared to usual care. Future research should focus on optimizing intervention design and accessibility for this population.
Area of Science:
- Nephrology
- Psychiatry
- Digital Health
Background:
- Depressive symptoms are common in patients undergoing chronic hemodialysis.
- Effective interventions are needed to manage depression in this vulnerable population.
Purpose of the Study:
- To evaluate the effectiveness of a guided internet-based self-help problem-solving therapy for hemodialysis patients experiencing depressive symptoms.
Main Methods:
- A cluster-randomized controlled trial was conducted across nine Dutch hospitals.
- 190 hemodialysis patients with depression scores (Beck Depression Inventory-II ≥10) were randomized.
- Intervention group received guided internet-based therapy; control group received usual care.
Main Results:
- No significant difference in depression scores (BDI-II) was observed between the intervention and control groups (mean difference -0.1, 95% CI -3.0; 2.7, p=0.94).
- Per-protocol analysis yielded similar results.
- No significant differences were found in secondary outcomes.
Conclusions:
- The guided internet-based self-help problem-solving therapy was not effective in reducing depressive symptoms in hemodialysis patients compared to usual care.
- Further research is recommended to improve the design and accessibility of digital interventions for depression in this patient group.
Objective:
To investigate the effectiveness of a guided internet-based self-help intervention for hemodialysis patients with depressive symptoms.
Method:
Chronic hemodialysis patients from nine Dutch hospitals with a depression score on the Beck Depression Inventory - second edition (BDI-II) of ≥10, were cluster-randomized into a five modules guided internet-based self-help problem solving therapy intervention or a parallel care-as-usual control group. Clusters were based on hemodialysis shift. The primary outcome depression was measured with the BDI-II. Analysis was performed with linear mixed models.
Results:
A total of 190 hemodialysis patients were cluster-randomized to the intervention (n = 89) or control group (n = 101). Post-intervention measurement was completed by 127 patients (67%) and more than half of the patients (54%) completed the intervention. No significant differences were found on the BDI-II score between the groups (mean difference - 0.1, 95%CI -3.0; 2.7, p = 0.94). Per protocol sensitivity analysis showed comparable results. No significant differences in secondary outcomes were observed between groups.
Conclusions:
Guided internet-based self-help problem solving therapy for hemodialysis patients with depressive symptoms does not seem to be effective in reducing these symptoms as compared to usual care. Future research should examine how to best design content and accessibility of an intervention for depressive symptoms in hemodialysis patients.
