The factors of perceived disease knowledge and self-care behavior in type 2 diabetic patients with chronic kidney disease: A cross-sectional study.

Chronic kidney diseases (CKD) is an important public health issue worldwide, and diabetes mellitus is the main cause of CKD. Having sufficient disease knowledge and good self-care behavior both help to prevent the progression of diabetes mellitus and CKD. This cross-sectional study enrolled 181 type 2 diabetic patients with CKD from July 2017 to October 2017. Perceived Kidney Knowledge survey and structured questionnaires of self-care behavior were used to measure perceived disease knowledge and CKD Self-Care (CKDSC) scales respectively with the determinants analyzed by linear regression. Meanwhile, socio-demographic information, kidney function and laboratory data were collected. Of 181 enrolled patients, the mean age was 66.8 ±â€…9.7 years, 59.1% were male and the mean estimated glomerular filtration rate was 33.1 ±â€…23.1 mL/min/1.73 m2. The mean scores of CKDSC and perceived disease knowledge were 63.2 and 22.4, respectively. High scores of disease knowledge were significantly correlated with low glycated hemoglobin (P = .03) and high scores of overall self-care behavior (P = .03) and aspects of self-care behavior, including diet (P = .003), exercise (P = .02), and home blood pressure monitoring (P = .04). The relationship between young age and high scores of disease knowledge was found (P = .001); however, old age was significantly associated with high scores of overall self-care behavior (P < .001) while additionally, married patients had high scores of regular medication behavior (P = .03). Our findings identified the significant factors correlated with disease knowledge and self-care behavior in type 2 diabetic patients with CKD. Healthcare givers should establish personalized health education plans to improve perceived disease knowledge and self-care behavior.

Shared decision-making for renal replacement treatment and illness perception in patients with advanced chronic kidney disease.

BACKGROUND: Current healthcare trends emphasize the use of shared decision-making (SDM) for renal replacement treatment (RRT) in patients with chronic kidney disease (CKD). This is crucial to understand the relationship between SDM and illness perception of CKD patients. Few studies have focused on SDM and illness perception status of CKD patients and the impact of illness perception on RRT after SDM. METHODS: In this cross-sectional study, we used a questionnaire with purposive sampling from March 2019 to February 2020 at the nephrology outpatient department of a medical center in southern Taiwan. The nephrology medical team in this study used the SHARE five-step model of SDM to communicate with the patients about RRT and Brief Illness Perception Questionnaire (BIPQ) was applied to evaluate illness perception of these patients at the beginning of SDM. According to the SDM decision time, the study participants were classified general and delayed SDM groups. The distribution between SDM groups was estimated using independent two sample t-test, chi-squared test or Fisher's exact test. The correlation between illness perception and SDM decision time were illustrated and evaluated using Spearman's correlation test. A p-value less than 0.05 is statistically significant. RESULTS: A total of 75 patients were enrolled in this study. The average time to make a dialysis decision after initiating SDM was 166.2 ± 178.1 days. 51 patients were classified as general group, and 24 patients were classified as delayed group. The median SDM decision time of delayed group were significantly longer than general group (56 vs. 361 days, P < 0.001). Our findings revealed that delayed group was significantly characterized with not created early surgical assess (delayed vs. general: 66.7% vs. 27.5%, p = 0.001) compared to general group. The average BIPQ score was 54.0 ± 8.1 in our study. We classified the patients into high and low illness perception group according to the median score of BIPQ. The total score of BIPQ in overall participants might increase by the SDM decision time (rho = 0.83, p = 0.830) and the linear regression line also showed consistent trends between BIPQ and SDM decision time in correspond cohorts. However, no statistically significant findings were found. CONCLUSIONS: The patients with advanced chronic kidney disease took an average of five and a half months to make a RRT decision after undergoing SDM. Although there is no statistical significance, the trend of illness perception seems correlated with decision-making time. The stronger the illness perception, the longer the decision-making time. Furthermore, shorter decision times may be associated with earlier establishment of surgical access. We need more research exploring the relationship between illness perception and SDM for RRT in CKD patients.

Mobile Health, Disease Knowledge, and Self-Care Behavior in Chronic Kidney Disease: A Prospective Cohort Study.

Mobile health (mHealth) management is an emerging strategy of care for patients with chronic diseases. However, the effect of mHealth management on clinical outcomes of patients with chronic kidney disease (CKD) has not been well-studied. The aim of this study was to investigate the additional influence of mHealth on disease knowledge and self-care behavior in CKD patients who had received traditional education. We designed and developed a new healthcare mobile application, called iCKD, which has several major features, including home-based physiological signal monitoring, disease health education, nutrition analysis, medication reminder, and alarms and a warning system. Trained nurses interviewed patients with CKD using structured questionnaires of disease knowledge and self-care behavior. After propensity score matching, we analyzed 107 patients who used iCKD and traditional education, and 107 who received traditional education. The patients who used iCKD had higher disease knowledge scores than those who received traditional education. In multivariate analysis, iCKD was significantly and positively associated with disease knowledge scores. Patients with high education levels could have greater disease knowledge through using mHealth. There was no significant difference in total scores of self-care behavior between the two groups. In conclusion, mHealth can significantly increase disease knowledge in patients with CKD.

The Relationship between Subtypes of Health Literacy and Self-Care Behavior in Chronic Kidney Disease.

Chronic kidney disease (CKD) is a global public health issue that is associated with high rates of morbidity and mortality. Self-care behavior has been associated with clinical outcomes in chronic diseases, and adequate self-care behavior may mitigate adverse outcomes. Health literacy may be an important factor associated with self-care. The aim of this study was to examine the relationships between different domains of self-care behavior and health literacy in patients with CKD. This study enrolled 208 patients with CKD stages 1-5 who were not undergoing renal replacement therapy at Kaohsiung Medical University Hospital from April 2019 to January 2020. Health literacy was measured using a multidimensional health literacy questionnaire covering the following five dimensions: accessing, understanding, appraising, and applying health information, and communication/interaction. The CKD Self-Care scale, which is a 16-item questionnaire with five domains including medication adherence, diet control, exercise, smoking behavior, and home blood pressure monitoring was used to assess self-care behavior. Among the 208 patients, 97 had sufficient or excellent health literacy, and 111 had inadequate or limited/problematic health literacy. A higher health literacy score was significantly correlated with greater self-care behavior. Among the five domains of self-care behavior, the patients who had sufficient or excellent health literacy had higher diet, exercise, and home blood pressure monitoring scores than those who had inadequate or limited/problematic health literacy. This study demonstrated that health literacy was significantly and positively correlated with self-care behavior in patients with CKD.

The interaction between self-care behavior and disease knowledge on the decline in renal function in chronic kidney disease.

Multidisciplinary care can improve the outcomes of chronic kidney disease (CKD), however the contribution of self-care behavior and knowledge about CKD is unclear. This study enrolled 454 participants with CKD stages 1-5 not on dialysis. Structured questionnaires were used to evaluate self-care behavior and kidney disease knowledge. Rapid decline in renal function was defined as the decline in estimated filtration rate > 3 ml/min per 1.73 m2/year within 1-year prior to enrollment. The mean age of all study participants was 65.8 ± 12.1 years and 55.9% were male. The elderly had better self-care behavior while younger participants had better disease knowledge. Both high self-care and high disease knowledge scores were significantly associated with and had a synergistic effect on decreasing the risk of rapid decline in renal function. CKD patients with better self-care behavior and better kidney disease knowledge had lower risk of rapid decline in renal function.

[Project to Increase the Usage Rate of iCKD Application Mobile Healthcare on Chronic Kidney Disease Patients].

BACKGROUND & PROBLEMS: In recent years, improved mobile capacities and mobile-device computing capabilities as well as a maturing mobile-communications infrastructure have combined to promote the development and widespread use of mobile healthcare applications. Mobile healthcare supports the self-management of chronic diseases, enhances healthcare quality, and reduces medical costs. Due to the low rate of iCKD usage in our hospital, we set up a project team that was tasked to improve the rate of iCKD usage among chronic disease patients. PURPOSE: To improve the iCKD usage rate from the current 5.8% to 9.3%. RESOLUTIONS: Questionnaire-based survey results indicated that the main reasons for the low iCKD usage rate in our hospital were: negative attitudes toward iCKD as a helpful tool in disease management, lack of awareness of the importance of using iCKD, unfamiliarity with how to operate smartphone applications, low numbers of iCKD physician referrals for patients, and slow Internet speeds. The improvement strategy included providing instructions on iCKD use, organizing a practical learning program, designing and printing a mobile healthcare referral form, and holding related events. RESULTS: The rate of iCKD usage increased to 21.3% after the intervention. CONCLUSIONS: The project team successfully increased the iCKD usage rate by getting more patients involved in mobile healthcare, which is expected to have a positive impact on the success of patient self-management.

Patient assessment of chronic kidney disease self-care using the chronic kidney disease self-care scale in Taiwan.

AIM: Self-care represents the 'action' element of self-management. This study aimed to use the chronic kidney disease self-care (CKDSC) scale to examine factors associated with self-care and aspects of self-care deficits among CKD patients in Taiwan. METHODS: A cross-sectional investigation was conducted using the CKDSC scale with 449 CKD patients in Taiwan. The CKDSC is a 16-item questionnaire with five subscales, including medication adherence, diet control, exercise, smoking behaviours and blood pressure monitoring. Patient demographic and clinical factors taht may affect CKD self-care were analyzed in the multivariable regression models. RESULTS: Overall CKDSC scores were significantly higher for women (P = 0.020), older patients (P < 0.001), higher education (P = 0.033), BMI <24 kg/m2 (P = 0.005), later CKD stage or participants in the CKD care programme. Early-stage CKD patients had significantly lower for medication adherence, diet control, and blood pressure monitoring. Patients who participated in the CKD care programme had higher for medication adherence, diet control and regular exercise habits. CONCLUSION: The CKDSC scale is a tool to assess patient self-care. However, given the CKDSC tool is in Chinese, future studies should validate it in CKD patients in other languages or countries before it can be considered for general use.

Association of Fluid Status and Body Composition with Physical Function in Patients with Chronic Kidney Disease.

BACKGROUND: Impairment of physical function and abnormal body composition are the major presentations in patients with chronic kidney disease (CKD). The aim of this study is to investigate the relationship between body composition and physical function in CKD patients. METHODS: This cross-sectional study enrolled 172 of CKD stages 1-5 from February 2013 to September 2013. Handgrip strength (upper extremity muscle endurance), 30-second chair-stand test (lower extremity muscle endurance) and 2-minute step test (cardiorespiratory endurance) were used as indices of physical function. Body composition, including fluid status (extracellular water/total body water, ECW/TBW), lean tissue index (LTI), and fat tissue index (FTI), was measured using a bioimpedance spectroscopy method. RESULTS: All patients with high ECW/TBW had lower handgrip strength and 30-second chair-stand than those with low ECW/TBW (P<0.001 and P = 0.002). CKD patients with high FTI had lower handgrip strength and 30-second chair-stand than those with low FTI (P<0.001 and P = 0.002). These patients with low LTI had lower handgrip strength than those with high LTI (P = 0.04). In multivariate analysis, high ECW/TBW was positively associated with decreased handgrip strength (ß = -41.17, P = 0.03) in CKD patients. High FTI was significantly correlated with decreased times of 30-second chair-stand (ß = -0.13, P = 0.01). There was no significant relationship between body composition and 2-minute step test. CONCLUSIONS: Our results show a significant association of impaired upper and lower extremity muscle endurance with high fluid status and fat tissue. Evaluation of body composition may assist in indentifying physical dysfunction earlier in CKD patients.

[Construction and Validation of a Chronic Kidney Disease Self-Care Scale].

BACKGROUND: As the prevalence of chronic kidney disease (CKD) increases, it is important to understand the self-care behavior of CKD patients. OBJECTIVES: To construct a CKD self-care scale and evaluate its metric properties. METHODS: Through literature review and clinical experience, question items were constructed and validated using item analysis. Factors analysis was used to validate the reliability and validity of the resultant questionnaire in a cross-sectional study. RESULTS: Six subscales containing a total of 20 items were extracted from the original CKD self-care scale using item and exploratory factor analysis. After performing three-time model goodness of fit, only five subscales including regular medication (5 items), diet control (4 items), regular exercise (3 items), smoking habits (2 items), and blood pressure management (2 items) were included in the final scale. The total explained variance of the final subscales was 74.96%. The reliability of the scale was examined and found to be satisfactory. Each absolute factor loading value fell between .72 and .94. The Cronbach's alpha for the overall scale was .83 and those for the five subscales were .83, .83, .94, .81, and .87, respectively. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: Appropriate assessment tools that allow CKD health educators to evaluate the self-care behaviors of patients effectively are needed. The valid and reliable CKD self-care scale that was developed in the present study is able to assist CKD health educators to quickly evaluate the self-care behavior of patients and to make appropriate health plans.

Quality of life predicts risks of end-stage renal disease and mortality in patients with chronic kidney disease.

BACKGROUND: Quality of life (QOL) may be associated with morbidity and survival in end-stage renal disease (ESRD), and is considered to be an important outcome measure for patients with chronic kidney disease (CKD). However, the prognostic role of QOL for survival in CKD remains unclear. We studied the relationship between QOL and risks of ESRD and mortality in CKD patients. METHODS: From 1 January 2007 to 31 December 2007, we prospectively used the Taiwan version of World Health Organization Quality-of-Life Questionnaire (Taiwan version) (WHOQOL-BREF(TW)) with 568 CKD patients at a medical centre in southern Taiwan, and patients were followed up for 1-2 years after enrollment. The primary outcome was the time to dialysis or death. We used Kaplan-Meier curve and Cox proportional hazard model for survival analyses. RESULTS: Of the 568 patients enrolled, 423 were able to complete the questionnaires, and their data were analysed. The median follow-up time was 410 days. Progressive decreases in scores of QOL in all domains were noted with decrease in eGFR. In unadjusted analysis, dialysis and death were associated with lower scores of total and all four domains of WHOQOL-BREF(TW). In adjusted analysis, the total scores and scores of both physical and psychological domains predicted dialysis and mortality (every 1-point decrease hazard ratio (HR): 1.050, 95% CI: 1.008-1.095, P = 0.020; HR: 1.179, CI: 1.033-1.346, P = 0.014; HR: 1.167, CI: 1.016-1.339, P = 0.028, respectively). The adjusted risks of ESRD and mortality also increased in patients in the lowest tertile of psychological domain (P < 0.01), and physical domain and total scores (P < 0.05). CONCLUSIONS: Physical, psychological and total scores of QOL are significantly correlated with increased risks of ESRD and death in CKD patients. QOL should be considered as an independent predictor of risks of ESRD and mortality.
