Predictors of self-care in kidney transplant patients according to preoperative dialysis: A comparative study

Background

Preemptive kidney transplantation (PKT) is associated with reduced dialysis-related morbidity and improved graft survival, which has led to an increase in the prevalence of PKT. The distinct clinical pathways of PKT and non-preemptive kidney transplantation (NPKT) patients may affect their ability to perform self-care, a key factor in post-transplant recovery. However, there is ongoing controversy regarding which group demonstrates better self-care abilities, highlighting the need to explore the factors influencing self-care in each group.

Objectives

This study aims to identify and compare predictors of self-care in PKT and NPKT groups.

Methods

We collected data from 209 KT recipients, consisting of 101 PKT and 108 NPKT patients, using self-administered questionnaires. These questionnaires assessed general and disease-specific characteristics, stress, social support, and self-care behaviors. Data were analyzed using descriptive statistics, t-tests, ANOVA, and multiple regression analysis.

Results

The study identified significant predictors of self-care among both PKT and NPKT patients. For PKT patients, marital status (β = .19, p = .033) and family support (β = .28, p = .006) are key predictors of self-care, with those having spousal support and strong family networks reporting better self-care levels. Conversely, in NPKT patients, significant predictors of self-care included marital status (β = .31, p = .001), employment status (β = .29, p = .007), post-transplantation duration (less than 36 month) (β = -.22, p = .015), post-transplantation duration (36-72 month) (β = -.33, p = .001), and stress levels (β = -.20, p = .028).

Conclusions

The study provides valuable insights into the predictors of self-care based on preoperative dialysis status, illustrating distinct predictors between the growing population of PKT and NPKT patients. These findings emphasize the need for personalized nursing strategies to enhance post-transplant self-care, tailored to individual patient characteristics.

Structural equation modeling for associated factors with self-care behavior among young and middle-aged hypertensive patients: a cross-sectional study

BACKGROUND

Self-determination theory (SDT) states that the self-care behaviors of patients with chronic illnesses are affected by an autonomy-supportive healthcare climate, satisfaction of autonomy, competence, and relatedness. Autonomy-supportive healthcare climate means to provide interpersonal conditions that support the person's volition, initiative, and integrity.

OBJECTIVE

The aim of this study was to explore the structural relationships of an autonomy-supportive healthcare climate, as well as the perception of illness consequences, autonomy, competence, and relatedness with self-care behaviors among adult outpatients with hypertension.

DESIGN

A cross-sectional survey was conducted in 2020 across three hospitals outpatient clinics in South Korea.

METHODS

A questionnaire package containing instruments measuring the perception of autonomy-supportive healthcare climate, autonomy, competence, relatedness, perception of illness consequence, self-care behaviors, sociodemographic data, and disease-related characteristics among the patients. The hypothetical model was derived from the SDT. Data were analyzed to test the hypothetical model and propose the final model.

RESULTS

Complete survey data was provided by 228 participants. Overall, the findings supported the hypothesized model (Goodness-of-Fit Index = 0.90 and Comparative Fit Index = 0.99). An autonomy-supportive healthcare climate and autonomy, competence, and relatedness directly influenced the self-care behaviors of adult hypertensive patients. However, the perception of illness consequences did not have a significant direct effect on self-care behavior.

CONCLUSION

Improving the autonomy-supportive healthcare climate, as well as positive perception of illness consequences, autonomy, competence, and relatedness among patients positively affects self-care behavior. Thus, an authentic partnership between healthcare providers and hypertensive patients is required to enhance trust, cooperation, and adaptation, consequently improving self-care behaviors among patients.

IMPACT STATEMENT

Autonomy-supportive healthcare climate was both directly and indirectly associated with self-care behavior that mediates autonomy, competence, and relatedness among young and middle-aged hypertensive patients.

Factors associated with self-management after hybrid revascularization in patients with peripheral artery disease: A structural equations model

AIM

To investigate the factors associated with self-management after hybrid revascularization in patients with lower extremity peripheral artery disease using a structural equation modelling approach.

DESIGN

A cross-sectional study was adopted.

METHODS

A total of 221 patients who underwent hybrid revascularization for peripheral artery disease of the lower limbs were included from outpatient clinics at a 1200-bed tertiary care hospital in Korea. Data were collected using a self-reported questionnaire between December 1, 2019, and August 31, 2020. Structural equation modelling was applied to test the hypothetical model.

RESULTS

The item mean score of participants' self-management was 6.28 (standard deviation, 0.83) out of 8. The structural equation modelling had a good fit index. Autonomy support from healthcare providers was directly associated with self-management (β = 0.20, p = 0.041). Illness perception directly (β = -0.33, p = 0.031) and indirectly (β = -0.19, p = 0.032) influenced self-management through competence and relatedness in patients with peripheral artery disease. The construct of autonomy support from healthcare providers, illness perception, competence and relatedness accounted for 49% of the variance in self-management. The Sobel test confirmed the statistically significant mediating effects of competence (z = -4.52, p < 0.001) and relatedness (z = -2.12, p < 0.001) on the relationship between illness perception and self-management.

CONCLUSION

Our findings revealed that autonomy support from healthcare providers and patients' illness perception directly influenced patients' self-management. Additionally, patients' illness perception can indirectly influence self-management through their perceived competence and relatedness.

IMPACT

Healthcare providers' autonomy support to patients may promote self-care behaviours, leading to greater autonomous motivation. Assessment of patients' illness perception before patient education is vital to designing effective self-management strategies which can improve patients' perceived competency and meaningful relatedness with healthcare providers.

Type D personality, cognitive illness perception, depression, approach coping, and self-management among older adults in long-term care hospitals: Structural equation modeling

This study aimed to construct a structural equation model to explore the relationship between Type D personality, cognitive illness perception, depression, approach-coping, and self-management. The study was conducted at two long-term care hospitals with 300 or more beds in Korea. Participants were 287 older patients from whom data were collected from February 17 to March 10, 2021, using a structured questionnaire comprising items on the following variables: Type D personality, cognitive illness perception, depression, approach coping, and self-management. Type D personality (β=-.601, p=.001), cognitive illness perception (β =.692, p <.001), depression (β =-.204, p =.011), and approach-coping (β =.326, p <.001) explained 78.8% of the total variance of self-management, highlighting their impact on how patients accept and manage a disease and their relevance to the self-management of older adults in long-term care hospitals.

Factors influencing the self-management of kidney transplant patients based on self-determination theory: a cross-sectional study

Background

Self-determination theory is useful for explaining how kidney transplant recipients self-manage their postoperative health, including drug regimens, but few studies have applied this theory to transplant recipients. This study aimed to examine the influence of health professionals’ autonomy support, autonomous motivation and competence on kidney transplant patients’ self-management based on the self-determination theory.

Methods

This study included 79 kidney transplant patients from one outpatient clinic in a general hospital in Seoul, Korea. Data on the health professionals’ support of patient autonomy and the kidney transplant patients’ autonomous motivation, competence, and self-management were collected from self-report questionnaires.

Results

The factors that influenced self-management behavior in kidney transplant patients were competence (β=0.377, P=0.001) and autonomous motivation (β=0.293, P=0.006). The explanatory power of these variables was 30.1%.

Conclusions

This study found that autonomous motivation and competence in kidney transplant patients affected their self-management, indicating that if healthcare professionals enhance patients’ competence and autonomous motivation, their self-management can be improved. The development of intervention programs that assist healthcare professionals in strengthening patients’ autonomous motivation and competence is recommended.

Mediating Role of Hope Between Social Support and Self-Management Among Chinese Liver Transplant Recipients: A Multi-Center Cross-Sectional Study

This study aimed to investigate the common status of self-management in liver transplant recipients and to explore the mediating role of hope in the relationship between social support and self-management. Two hundred and ten liver transplant recipients from two tertiary hospitals were included. Questionnaires were used for general demographic information, the Perceived Social Support Scale, the Herth Hope Index, and the Self-Management Questionnaire for Liver Transplantation Recipients. Lifestyle management of liver transplant recipients was good, while the communication with physicians, cognitive symptom management, and exercise dimensions were less than satisfactory. Minimal assurance of family and education levels were significantly associated with self-management. Social support was positively correlated with self-management and hope (r = .31, p < .01; r = .40, p < .01). Hope was positively correlated with self-management (r = .39, p < .01). Additionally, the effect of social support on self-management was partially mediated (β = .17, p < .01) by hope. The proportion of mediation of hope was 40.09%. Therefore, well-designed interventions that boost both social support and hope may help improve self-management behavior in liver transplant recipients.

Feasibility and preliminary effects of a theory-based self-management program for kidney transplant recipients: A pilot study

Self-care activities are important to prevent transplant-related side effects and complications among kidney transplant recipients. Therefore, we developed a theory-based self-management program for kidney transplant recipients hospitalized after surgery. This study aimed to examine the feasibility of the program and to identify its preliminary effects on autonomy, competence, and self-care agency. We assessed feasibility using quantitative data collected based on a single group repeated-measures design, along with qualitative data such as patients' feedback on satisfaction during patient counseling. The program comprised video education and individual counseling by nurses. Thirty patients completed this program. Outcome variables were measured thrice: before education, immediately following the first week of video education, and after two consecutive weeks of counseling. A repeated measures ANOVA showed a statistically significant increase in autonomy (F = 5.03, p = .038), competence (F = 17.59, p < .001), and self-care agency (F = 24.19, p < .001). Our pilot study provided preliminary evidence supporting the feasibility for implementation of the theory-based self-management program, and suggesting its preliminary effects in improving autonomy, competence, and self-care agency among kidney transplant recipients. Further research is needed to examine the short- and long-term effects of this program in a longitudinal, randomized control study with a larger sample.

Psychometric properties of the Chinese Version of the Readiness for Hospital Discharge Scale for people living with HIV

Objective

The study was conducted to validate the reliability and factor structure of the Chinese version of the Readiness for Hospital Discharge Scale (RHDS-CH) for people living with HIV (PLWH).

Methods

From May 2017 to November 2017, a cross-sectional survey was performed in two AIDS inpatient departments located in two cities in Hunan, China. Reliability was evaluated by examining the internal consistency and split-half reliability of the items. A confirmatory factor analysis was performed to assess the factor structure of the RHDS-CH, and the model was revised according to the modification index.

Results

Cronbach’s α for the RHDS-CH was 0.912, and the split-half reliability of the total scale was 0.831. Initially, the results of the confirmatory factor analysis indicated that the sample did not fit this four-factor model and its 23 items well (χ²/df = 3, GFI =0.772, TLI = 0.823, CFI = 0.844, RMSEA = 0.100). To improve the model fit indices, we performed model modification with the guidance of modification indices. Finally, the model fit indices showed an acceptable fit to the data (χ²/df = 2.141, GFI = 0.844, TLI = 0.899, CFI = 0.915, RMSEA = 0.075). Coefficients of corrected item-total correlation of the RHDS-CH ranged from 0.435 to 0.726.

Conclusion

This study is the first to examine the psychometric properties of the RHDS-CH for PLWH. Our findings showed good reliability and confirmed the four-factor structure model for PLWH.

Mediation Effects of Basic Psychological Needs Between Autonomy Support from Healthcare Providers and Self-Management Among Cancer Survivors

Objectives

This study examined the mediating effects of basic psychological needs between patient autonomy support from healthcare providers, and self-management among cancer survivors.

Methods

This study collected data from 148 cancer patients who had visited D hospitals in B city, Korea. A structured questionnaire was distributed to determine patient characteristics, healthcare provider autonomy support, basic psychological needs, and self-management. Data were analyzed using descriptive statistics, Pearson’s correlation coefficient, and regression analysis that implemented Baron and Kenny’s method for mediation were used for analyses.

Results

Self-management was significantly correlated with the level of healthcare provider autonomy support (r = 0.38, p < 0.001), autonomy (r = 0.40, p < 0.001), competence (r = 0.25, p = 0.002), and relatedness (r = 0.32, p < 0.001). Furthermore, autonomy (β = 0.30, p < 0.001) and relatedness (β = 0.22, p = 0.008) had partial mediating effects on the relationship between healthcare provider autonomy support and self-management (Z = 3.13, p = 0.002 and Z = 2.29, p = 0.022, respectively).

Conclusion

Autonomy and relatedness mediated the impact of healthcare provider autonomy support for self-management among cancer survivors. This suggests that strategies for enhancing autonomy and relatedness should be considered when developing self-management interventions for cancer survivor patients.

Analysis of mortality prognostic factors using model for end-stage liver disease with incorporation of serum-sodium classification for liver cirrhosis complications: A retrospective cohort study

Since the progression of cirrhosis is accelerated each time a complication recurs, the management and treatment of the complication is critical in enhancement of the quality of life and expectation of life in patients. The use of model for end-stage liver disease with incorporation of serum-sodium (MELD-Na) with physiological indicators can be used to assess severity and differentiate therapeutic interventions.This study is aimed to determine the mean survival period and cumulative survival rate by classifying patients into high-risk and low-risk groups based on MELD-Na, a predictor of mortality in liver disease, and to investigate the mortality prognostic factors.A retrospective cohort study, which follows the STROBE checklist, was performed. 263 patients who were diagnosed with liver cirrhosis complications for the first time and hospitalized were selected as the subjects of this study. The collected data were analyzed based on the survival package provided by the statistical program R version 3.4.2.Subjects were classified into high-risk and low-risk groups using MELD-Na 14 points where sensitivity and specificity crossed the cut-off point. Gender, age, and primary caregiver were significant variables in the mortality high-risk group, and AST, albumin, and primary caregiver were significant variables in the mortality low-risk group. Based on these mortality prognostic factors, it is possible to present the factors affecting mortality in patients who were diagnosed with liver cirrhosis complications for the first time. The classification of patients by risk level could be the foundation to provide accurate guidelines for management and it is necessary to modify prognostic factors and apply nursing interventions to manage complications.

[Structural Equation Modeling of Self-Care Behaviors in Kidney Transplant Patients Based on Self-Determination Theory]

PURPOSE

The purpose of this study was to test a hypothesis explaining direct and indirect relationships among the factors affecting self-care behaviors of kidney transplant patients, based on self-determination theory.

METHODS

Data were collected from 222 outpatients with kidney transplantation. The endogenous and exogenous variables of the hypothetical model consisted of healthcare provider's autonomy support, duration after kidney transplantation, basic psychological need satisfaction, autonomous and controlled motivation, depression, and self-care behaviors. Collected data were analyzed using SPSS/WIN 24.0 and AMOS 24.0.

RESULTS

The hypothetical model demonstrated a good fit: RMSEA=.06, SRMR=.04, TLI=.94, CFI=.97. Statistically significant explanatory variables for the self-care behaviors of kidney transplant patients were duration after transplantation and basic psychological need satisfaction. Healthcare provider's autonomy support was indirectly significant, while autonomous motivation, controlled motivation and depression were not statistically significant for self-care behaviors. The variables accounted for 59.5% of the self-care behaviors of kidney transplant patients.

CONCLUSION

It is necessary to develop an autonomy support program for healthcare providers to enhance the self-care behaviors of kidney transplant patients. Preventing the deterioration of self-care behaviors will be possible by conducting this program at one year and six years post-transplantation. In addition, the results suggest the need to developing personalized autonomy support programs for healthcare providers that can meet the basic psychological need satisfaction of kidney transplant patients.
