SELF-EFFICACY AND LONG-TERM MEDICATION USE IN PATIENTS WITH CHRONIC KIDNEY DISEASE

Interventions for improving health literacy in people with chronic kidney disease

BACKGROUND

Low health literacy affects 25% of people with chronic kidney disease (CKD) and is associated with increased morbidity and death. Improving health literacy is a recognised priority, but effective interventions are not clear.

OBJECTIVES

This review looked the benefits and harms of interventions for improving health literacy in people with CKD.

SEARCH METHODS

We searched the Cochrane Kidney and Transplant Register of Studies up to 12 July 2022 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. We also searched MEDLINE (OVID) and EMBASE (OVID) for non-randomised studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and non-randomised studies that assessed interventions aimed at improving health literacy in people with CKD.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed studies for eligibility and performed risk of bias analysis. We classified studies as either interventions aimed at improving aspects of health literacy or interventions targeting a population of people with poor health literacy. The interventions were further sub-classified in terms of the type of intervention (educational, self-management training, or educational with self-management training). Results were expressed as mean difference (MD) or standardised mean difference (SMD) with 95% confidence intervals (CI) for continuous outcomes and risk ratios (RR) with 95% CI for dichotomous outcomes.

MAIN RESULTS

We identified 120 studies (21,149 participants) which aimed to improve health literacy. There were 107 RCTs and 13 non-randomised studies. No studies targeted low literacy populations. For the RCTs, selection bias was low or unclear in 94% of studies, performance bias was high in 86% of studies, detection bias was high in 86% of studies reporting subjective outcomes and low in 93% of studies reporting objective outcomes. Attrition and other biases were low or unclear in 86% and 78% of studies, respectively. Compared to usual care, low certainty evidence showed educational interventions may increase kidney-related knowledge (14 RCTs, 2632 participants: SMD 0.99, 95% CI 0.69 to 1.32; I² = 94%). Data for self-care, self-efficacy, quality of life (QoL), death, estimated glomerular filtration rate (eGFR) and hospitalisations could not be pooled or was not reported. Compared to usual care, low-certainty evidence showed self-management interventions may improve self-efficacy (5 RCTs, 417 participants: SMD 0.58, 95% CI 0.13 to 1.03; I² = 74%) and QoL physical component score (3 RCTs, 131 participants: MD 4.02, 95% CI 1.09 to 6.94; I² = 0%). There was moderate-certainty evidence that self-management interventions probably did not slow the decline in eGFR after one year (3 RCTs, 855 participants: MD 1.53 mL/min/1.73 m², 95% CI -1.41 to 4.46; I² = 33%). Data for knowledge, self-care behaviour, death and hospitalisations could not be pooled or was not reported. Compared to usual care, low-certainty evidence showed educational with self-management interventions may increase knowledge (15 RCTs, 2185 participants: SMD 0.65, 95% CI 0.36 to 0.93; I² = 90%), improve self-care behaviour scores (4 RCTs, 913 participants: SMD 0.91, 95% CI 0.00 to 1.82; I² =97%), self-efficacy (8 RCTs, 687 participants: SMD 0.50, 95% CI 0.10 to 0.89; I² = 82%), improve QoL physical component score (3 RCTs, 2771 participants: MD 2.56, 95% CI 1.73 to 3.38; I² = 0%) and may make little or no difference to slowing the decline of eGFR (4 RCTs, 618 participants: MD 4.28 mL/min/1.73 m², 95% CI -0.03 to 8.85; I² = 43%). Moderate-certainty evidence shows educational with self-management interventions probably decreases the risk of death (any cause) (4 RCTs, 2801 participants: RR 0.73, 95% CI 0.53 to 1.02; I² = 0%). Data for hospitalisation could not be pooled.

AUTHORS' CONCLUSIONS

Interventions to improve aspects of health literacy are a very broad category, including educational interventions, self-management interventions and educational with self-management interventions. Overall, this type of health literacy intervention is probably beneficial in this cohort however, due to methodological limitations and high heterogeneity in interventions and outcomes, the evidence is of low certainty.

Relationship between patient activation and self-efficacy among patients undergoing hemodialysis: a cross-sectional study

Background

Patient activation in chronic kidney disease (CKD) is increasingly being prioritized and considered a quality metric in CKD. Given the importance of patients’ activation in improving the quality of chronic disease care, this study aimed to assess patients’ activation levels and its relationship with self-efficacy among patients undergoing hemodialysis.

Methods

In this cross-sectional study, a total of 180 patients undergoing maintenance hemodialysis were selected by random sampling from the largest hemodialysis center (dialysis center of Emam Reza hospital, Tabriz) in Iran. Data were collected by demographics, patient activation measure, and chronic kidney disease self-efficacy (CKD-SE) scale from March to May 2021. Collected data were analyzed using SPSS software (ver. 26) using ANOVA, t-test, Pearson correlation coefficient, and multiple regression tests.

Results

The majority of the participants (35%) were at level 1 of activation and only 28.9% of the individuals were at level 4. According to the results, the mean score of self-efficacy in patients undergoing hemodialysis (in a possible range of 0–10) was 5.50 ± 1.45. Multiple regression analysis showed that factors including self-efficacy, educational level, and marital status were significant predictors of change in patient activation (R2 = 0.85, adjusted R2 = 0.66, p < 0.001). The results showed that self-efficacy was the main predictor of patient activation (β = 0.49, p < 0.001).

Conclusion

According to the result, improving the patients' self-efficacy could improve the patient's activation. Moreover, patients with lower educational level reported the lower activation score; therefore, health care providers should improve the knowledge of patients with lower educational level, encourage them to be more active in their health care, and help them in providing more tailored strategies to improve the quality of care more efficiently. Furthermore, Measuring patients' activation level at admission to the dialysis unit is recommended for all patients undergoing hemodialysis.

Evaluation of health-promoting self-care behaviors in hypertensive patients with concomitant chronic kidney disease in primary care

Aim:

This study was to investigate the relationships among health behaviors and quality of life (QOL) and to test a proposed model among people with hypertension and concomitant chronic kidney disease (CKD) in primary care. In addition, the mediation effect of modifiable risk factors between self-care health behaviors and QOL was examined.

Methods:

This study was prospective, conducted in the centers of primary medical care in the period from January 2018 to January 2020. In total, 170 patients diagnosed with hypertension and CKD at least 12 months previously were included in this study. The following parameters were measured: self-efficacy, self-care health behaviors with the subscales of health responsibility, exercise, consumption of a healthy diet, stress management, and smoking cessation; modifiable risk score; and QOL (assessed using the 36-item Short-Form Health Survey instrument).

Results:

Self-efficacy had a significantly positive direct effect on self-care health behaviors, with a standardized regression coefficient of 0.87 (P = 0.007), a negative indirect effect on risk factors, with a standardized regression coefficient of 0.11 (P = 0.006), and a positive indirect effect on QOL, with a standardized regression coefficient of 0.62 (P = 0.008). Self-care health behaviors had a significantly positive direct effect on QOL, with a standardized regression coefficient of 0.72 (P = 0.012); there was also an indirect effect of 0.053 (P = 0.004). The direct effect of risk factors on QOL was significant, with a standardized regression coefficient of 0.44 (P = 0.018). The direct effect of self-care health behaviors on QOL was 0.77 (P = 0.008), which has been reduced to 0.72 (P = 0.012). The reduced effect of 0.05 was significant (P = 0.004), confirming the mediating role of modified risk factors.

Conclusions:

This study indicates health-promoting behaviors in hypertensive patients with CKD have a potential impact on their QOL in primary care. Primary care physicians should focus on motivation strategies to encourage individuals to perform self-care health-promoting behaviors associated with the improved QOL, in order to achieve better outcomes in risk factor management.

A Chinese and Western medication adherence scale in patients with Chronic Kidney Disease

OBJECTIVE

The self-reported scale is a widely used method to assess patients' medication adherence in clinical practice, but there is still a lack of medicine adherence measurement scale for patients with Chronic Kidney Disease (CKD). Therefore, this study aimed to develop a medication adherence measurement scale of traditional Chinese medicine and Western medicine, providing a tool for evaluating medicine adherence of CKD patients.

METHODS

In the preliminary stage, we formed the prediction scale after three rounds Delphi method and it was filled by 20 patients, who were selected randomly. After pre-investigation and language adaption, we adjusted the prediction measurement scale which included 31 items based on Knowledge-Attitude-Belief Theory. Then, 222 CKD patients in Guangdong Hospital of traditional Chinese Medicine were investigated by this 31-item scale. We screened 31 items by Items analysis theory, including critical ratio, item correlation analysis, internal consistency analysis, principal component analysis and other methods. The left 26 items made up a formal scale. We collected and analyzed data of the 26-item scale and Chinese version of MGL scale, and took their scores correlation analysis as the criterion validity of the 26-item scale. At the same time, we evaluated content validity, Cronbach alpha coefficient and retest reliability of the 26-item scale.

RESULTS

We developed a scale with 26 items and 5 dimensions finally. In the validation analysis, the scale had good construct validity and content validity. The Pearson relation index between respective scores of the scale and Chinese version of MGL scale was 0.426, P<0.01. The scale also had good reliability as its 0.915 in Cronbach alpha, 0.753 in retest reliability and P<0.01.

CONCLUSION

The scale revealed great reliability and validity, which could be used as a measurement tool to evaluate the medication adherence of patients with CKD.

Self-management interventions for adults with chronic kidney disease: a scoping review

OBJECTIVE

To systematically identify and describe self-management interventions for adult patients with chronic kidney disease (CKD).

SETTING

Community-based.

PARTICIPANTS

Adults with CKD stages 1-5 (not requiring kidney replacement therapy).

INTERVENTIONS

Self-management strategies for adults with CKD.

PRIMARY AND SECONDARY OUTCOME MEASURES

Using a scoping review, electronic databases and grey literature were searched in October 2016 to identify self-management interventions for adults with CKD stages 1-5 (not requiring kidney replacement therapy). Randomised controlled trials (RCTs), non-RCTs, qualitative and mixed method studies were included and study selection and data extraction were independently performed by two reviewers. Outcomes included behaviours, cognitions, physiological measures, symptoms, health status and healthcare.

RESULTS

Fifty studies (19 RCTs, 7 quasi-experimental, 5 observational, 13 pre-post intervention, 1 mixed method and 5 qualitative) reporting 45 interventions were included. The most common intervention topic was diet/nutrition and interventions were regularly delivered face to face. Interventions were administered by a variety of providers, with nursing professionals the most common health professional group. Cognitions (ie, changes in general CKD knowledge, perceived self-management and motivation) were the most frequently reported outcome domain that showed improvement. Less than 1% of the interventions were co-developed with patients and 20% were based on a theory or framework.

CONCLUSIONS

There was a wide range of self-management interventions with considerable variability in outcomes for adults with CKD. Major gaps in the literature include lack of patient engagement in the design of the interventions, with the majority of interventions not applying a behavioural change theory to inform their development. This work highlights the need to involve patients to co-developed and evaluate a self-management intervention based on sound theories and clinical evidence.

Improvement of Immunosuppressive Medication Adherence Using a SystemCHANGE Intervention: Case Study of an Older Adult Kidney Transplant Recipient

This article reports a case study of an older adult kidney transplant recipient with poor medication adherence enrolled in an innovative six-month SystemCHANGE intervention that seeks to systematically improve medication adherence by identifying and shaping routines, involving others in routines, and using medication-taking feedback through small, patient-led experiments. Medication adherence increased immediately and was sustained throughout the intervention and maintenance phases. This is the first case study to demonstrate effectiveness of the SystemCHANGE intervention for promoting medication adherence in a kidney transplant recipient. The intervention improved the timing of doses by linking them to a regularly occurring behavior and providing feedback. The SystemCHANGE intervention represents a systems-thinking approach for both provider and patients, and gives healthcare providers the tools needed to assist patients in using habits and routines, and feedback to improve medication taking and timing.

The Perceived Medical Condition Self-Management Scale can be applied to patients with chronic kidney disease

Chronic Kidney Disease (CKD) is a major burden on patients and the health care system. Treatment of CKD requires dedicated involvement from both caretakers and patients. Self-efficacy, also known as perceived competence, contributes to successful maintenance of patient's CKD self-management behaviors such as medication adherence and dietary regulations. Despite a clear association between self-efficacy and improved CKD outcomes, there remains a lack of validated self-report measures of CKD self-efficacy. To address this gap, the Perceived Kidney/Dialysis Self-Management Scale (PKDSMS) was adapted from the previously validated Perceived Medical Condition Self-Management Scale. We then sought to validate this using data from two separate cohorts: a cross-sectional investigation of 146 patients with end-stage renal disease receiving maintenance hemodialysis and a longitudinal study of 237 patients with CKD not receiving dialysis. The PKDSMS was found to be positively and significantly correlated with self-management behaviors and medication adherence in both patient cohorts. The PKDSMS had acceptable reliability, was internally consistent, and exhibited predictive validity between baseline PKDSMS scores and self-management behaviors across multiple time points. Thus, the PKDSMS is a valid and reliable measure of CKD patient self-efficacy and supports the development of interventions enhancing perceived competence to improve CKD self-management.
