The (cost) effectiveness of guided internet-based self-help CBT for dialysis patients with symptoms of depression: study protocol of a randomised controlled trial

Depression, anxiety and quality of life of hemodialysis patients before and during the COVID-19 pandemic

OBJECTIVE

To investigate the impact of the coronavirus pandemic on mental health in hemodialysis patients, we assessed depression, anxiety and quality of life with valid mental health measures before and after the start of the pandemic.

METHODS

Data were used from 121 hemodialysis patients from the ongoing prospective multicenter DIVERS-II study. COVID-19 related stress was measured with the Perceived Stress Scale - 10, depression with the Beck Depression Inventory - second edition (BDI-II)), anxiety with the Beck Anxiety Inventory (BAI) and quality of life with the Short Form - 12 (SF-12). Scores during the first and second COVID-19 wave in the Netherlands were compared to data prior to the pandemic with linear mixed models.

RESULTS

No significant differences were found in BDI-II, BAI and SF-12 scores between before and during the pandemic. During the first wave, 33% of participants reported COVID-19 related stress and in the second wave 37%. These patients had higher stress levels (mean difference (MD) 4.7 (95%CI 1.5; 8.0), p = 0.005) and BDI-II scores (MD 4.9 (95%CI 0.7; 9.0), p = 0.021) and lower SF-12 mental component summary scores (MD -5.3 (95%CI -9.0, -1.6), p = 0.006) than patients who did not experienced COVID-19 stress. These differences were already present before the pandemic.

CONCLUSION

The COVID-19 pandemic does not seem to influence mental health in hemodialysis patients. However, a substantial subgroup of patients with pre-existent mental health problems may be more susceptible to experience COVID-19 related stress.

Validation of Two Screening Tools for Anxiety in Hemodialysis Patients

Background: Symptoms of anxiety are often unrecognized and untreated in dialysis patients. We investigated the diagnostic accuracy of two widely used screening tools for anxiety in hemodialysis patients. Methods: For this cross-sectional validation study, chronic hemodialysis patients from eight dialysis centers in the Netherlands were included. The Beck Anxiety Inventory (BAI) and Hospital Anxiety and Depression Scale—Anxiety subscale (HADS-A) were validated by the Mini International Neuropsychiatric Inventory (MINI) diagnostic interview. Receiver operating characteristic curves were used to determine the optimal cut-off values. Results: Of 65 participants, 13 (20%) were diagnosed with one or more anxiety disorders on the MINI, of which 5 were included in the analysis. ROC curves showed a good diagnostic accuracy of the BAI and HADS-A. The optimal cut-off value for the BAI was ≥13 (sensitivity 100%, specificity 85%) and for the HADS-A was ≥10 (sensitivity 80%, specificity 100%). Conclusions: Based on our limited data, both the BAI and the HADS-A seem to be valid screening instruments for anxiety in hemodialysis patients that can be used in routine dialysis care. The HADS-A consists of fewer items and showed fewer false-positive results than the BAI, which might make it more useful in clinical practice.

Internet-based treatment for depressive symptoms in hemodialysis patients: A cluster randomized controlled trial

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.

Perspectives on mental health among patients receiving dialysis

BACKGROUND

Diminished mental health is associated with increased morbidity and mortality and may contribute to loss of independence and motivation in patients receiving dialysis and their caregivers. Increased understanding of the patient perspective on triggers, impacts and strategies for managing mental health may inform ways to address mental health conditions in this population.

METHODS

A secondary thematic analysis was undertaken using data from the Standardized Outcomes in Nephrology (SONG)-Hemodialysis and SONG-Peritoneal Dialysis projects. We extracted and analysed data on the perceived causes, meaning, impact and management of mental health in patients receiving dialysis from 26 focus groups (in six countries), multinational Delphi surveys and consensus workshops.

RESULTS

A total of 644 patients and caregivers participated. We identified five themes: bound to dialysis (forced into isolation, enslaved to a machine, stress of relentless planning and grieving the loss of a normal life), underrecognized and ignored (missed by health practitioners, need for mental health support), an uncertain future (dreading complications, coming to terms with mortality), developing self-reliance (vulnerability in being solely responsible for dialysis, sustaining motivation for dialysis, necessity for self-vigilance and taking charge to regulate emotions) and responding to a lifestyle overhaul (guilt of burdening family, controlling symptoms for overall mental wellness, protecting independence and trying to feel grateful).

CONCLUSIONS

Patients receiving dialysis and their caregivers endure mental and emotional distress attributed to the burden of dialysis, lifestyle restrictions, the constant threat of death and symptom burden, which can impair motivation for self-management. Increased attention to monitoring and management of mental health in this population is needed.
