Insights
Low medication adherence in adults with chronic kidney disease (CKD) is linked to a higher risk of CKD progression. This finding highlights the importance of adherence for managing kidney disease outcomes.
Area of Science:
- Nephrology
- Clinical Epidemiology
Background:
- Medication nonadherence is a significant issue in the general population, leading to adverse health outcomes.
- Limited data exists on medication adherence patterns and their impact among adults diagnosed with chronic kidney disease (CKD).
Purpose of the Study:
- To investigate the association between self-reported medication adherence and the progression of CKD.
- To examine the relationship between medication adherence and all-cause mortality in patients with CKD.
Main Methods:
- A prospective observational study involving 3305 adults with mild-to-moderate CKD from the Chronic Renal Insufficiency Cohort (CRIC) Study.
- Baseline medication adherence was self-reported and categorized into high, medium, and low groups.
- CKD progression (defined as a 50% eGFR decline or ESRD) and all-cause death were analyzed using multivariable Cox proportional hazards models.
Main Results:
- The majority of participants (68%) reported high medication adherence, with 17% reporting medium and 15% reporting low adherence.
- Over a median follow-up of 6 years, low adherence was significantly associated with an increased risk of CKD progression (HR=1.27, 95% CI=1.05-1.54) after adjustments.
- A trend towards increased all-cause mortality risk was observed in the low adherence group (HR=1.14, 95% CI=0.88-1.47), but it did not reach statistical significance.
Conclusions:
- Low self-reported medication adherence at baseline is a significant predictor of CKD progression in adults with mild-to-moderate CKD.
- Further research is warranted to elucidate the underlying mechanisms and develop targeted interventions to enhance medication adherence in this patient population.
Introduction:
In the general population, medication nonadherence contributes to poorer outcomes. However, little is known about medication adherence among adults with chronic kidney disease (CKD). We evaluated the association of self-reported medication adherence with CKD progression and all-cause death in patients with CKD.
Methods:
In this prospective observational study of 3305 adults with mild-to-moderate CKD enrolled in the Chronic Renal Insufficiency Cohort (CRIC) Study, the baseline self-reported medication adherence was assessed by responses to 3 questions and categorized as high, medium, and low. CKD progression (50% decline in eGFR or incident end-stage renal disease) and all-cause death were measured using multivariable Cox proportional hazards.
Results:
Of the patients, 68% were categorized as high adherence, 17% medium adherence, and 15% low adherence. Over a median follow-up of 6 years, there were 969 CKD progression events and 675 deaths. Compared with the high-adherence group, the low-adherence group experienced increased risk for CKD progression (hazard ratio = 1.27, 95% confidence interval = 1.05, 1.54) after adjustment for sociodemographic and clinical factors, cardiovascular medications, number of medication types, and depressive symptoms. A similar association existed between low adherence and all-cause death, but did not reach standard statistical significance (hazard ratio = 1.14 95% confidence interval = 0.88, 1.47).
Conclusion:
Baseline self-reported low medication adherence was associated with an increased risk for CKD progression. Future work is needed to better understand the mechanisms underlying this association and to develop interventions to improve adherence.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
