Unfortunately, poor patient adherence is a widespread problem in Adherence is a major problem in patients with chronic kidney disease. Patients can be non- adherent with different aspects of their treatment, which includes medications, treatment reg- imens, and dietary and fluid restrictions. Although many lessons have been learned from adherence research, the evidence of how to modify adherence is somewhat mixed. To mini- health care that carries with it sub- mize nonadherence, interventions need to focus on both patient factors and the extent to stantial medical, social, and economic which relationships and system problems compromise the patient’s ability to adhere to med- consequences, particularly among ication and treatment plans. There continues to be a tendency to focus on the patient as the patients with chronic kidney disease reason for problems with adherence, ignoring other factors such as the patient-health care (CKD). Much research has been provider relationships and the health care system that surrounds the patient. These latter fac- devoted to understanding patient tors can have a considerable effect on adherence. The nurse can develop a strong relationship nonadherence, but has generally of support with the patient, identify barriers, and offer strategies to help patients improve failed to demonstrate that any patient adherence. demographic or psychological char- acteristics are consistent predictors of adherence (Cvengros, Christiansen, & Lawton, 2004).

  3. 3. Figure 1 resources and the motivation to adhere Interacting Factors Affecting Adherence to the treatment protocol (Morgan, 2000). Individuals with chronic illness who experience a diminished sense of con- trol often seek alternative methods to re-establish control. These behaviors may manifest in positive or negative Patient Provider ways. Many theories suggest that a per- ceived lack of control over the disease process and/or the dialysis procedure may help to explain nonadherence (Cvengros et al., 2004). Patients who shortened treatments were more likely to be bothered by the effects of kidney Health disease on their daily lives and more Care System likely to report perceived lack of con- trol over their future health (Kutner et al., 2002).
