Insights
Cognitive Behaviour Therapy (CBT) significantly improved adherence to dialysis, fluid, drug, and diet regimens in chronic kidney disease (CKD) patients undergoing haemodialysis. CBT demonstrated superior outcomes compared to non-directive counselling.
Area of Science:
- Nephrology
- Psychology
- Clinical Medicine
Background:
- Patients with chronic kidney disease (CKD) undergoing haemodialysis frequently encounter psychosocial challenges impacting treatment adherence.
- Poor adherence to therapeutic regimens exacerbates clinical complications in CKD patients.
Purpose of the Study:
- To evaluate the efficacy of Cognitive Behaviour Therapy (CBT) in enhancing adherence to dialysis, fluid intake, medication, and diet.
- To compare the impact of CBT versus non-directive counselling on adherence and clinical outcomes in haemodialysis patients.
Main Methods:
- A randomized controlled trial involving 67 CKD patients undergoing haemodialysis in India.
- The experimental group received CBT, while the control group received non-directive counselling over a six-month period.
- Adherence was measured using a validated haemodialysis adherence scale; effect sizes were calculated using Cohen's d.
Main Results:
- The CBT group showed significant reductions in interdialytic weight gain and blood pressure.
- Significant improvements were observed in haemoglobin levels and adherence to dialysis, fluids, diet, and drugs in the CBT group.
- These improvements were statistically significantly greater in the CBT group compared to the control group (P = 0.001).
Conclusions:
- Cognitive Behaviour Therapy (CBT) is more effective than non-directive counselling for improving therapeutic adherence in CKD patients on haemodialysis.
- CBT positively impacts physiological and clinical parameters, offering a valuable intervention for this patient population.
Objectives:
Patients with chronic kidney disease (CKD) undergoing haemodialysis often experience a myriad of psychosocial problems, resulting in poor adherence to their therapeutic regimen. This study aimed to examine the effect of cognitive behaviour therapy (CBT) on dialysis, fluid, drug and diet adherence among a previously reported sample of CKD patients undergoing haemodialysis.
Methods:
A randomised controlled trial was conducted between January 2013 to Febrary 2014 on a random selection of 67 CKD patients attending a tertiary multispecialty hospital in India. The experimental group (n = 33) was exposed to CBT, whereas the control group (n = 34) received non-directive counselling. A haemodialysis adherence scale was developed and used to assess adherence to the treatment regimen. The effect size was calculated using Cohen's d statistics.
Results:
At six months, mean reductions from baseline were observed in the experimental group in terms of interdialytic weight gain (-1.23 kg; effect size: 0.57), systolic blood pressure (-22.18 mmHg; effect size: 0.71) and diastolic blood pressure (-10.06 mmHg; effect size: 0.72), whereas mean increases were noted in haemoglobin (+0.75 g/dL; effect size: 0.31) and adherence to dialysis (+0.94; effect size: 0.51), fluids (+16.34; effect size: 2.30), diet (+61.19; effect size: 4.75) and drugs (+10.73; effect size: 1.3). Differences from baseline were significantly higher in the experimental group compared to the control group (P = 0.001 each).
Conclusion:
These results show that CBT is more effective than non-directive counselling for improving therapeutic adherence and physiological, clinical parameters among CKD patients undergoing haemodialysis.
