Psychosocial determinants of healthcare use costs in kidney transplant recipients

Quality of life and psychological distress in end-stage renal disease patients undergoing hemodialysis and transplantation

BACKGROUND

Among diverse profound impacts on patients' quality of life (QoL), end-stage renal disease (ESRD) frequently results in increased levels of depression, anxiety, and stress. Renal replacement therapies such as hemodialysis (HD) and transplantation (TX) are intended to enhance QoL, although their ability to alleviate psychological distress remains uncertain. This research posits the existence of a significant correlation between negative emotional states and QoL among ESRD patients, with varying effects observed in HD and TX patients.

AIM

To examine the relationship between QoL and negative emotional states (depression, anxiety, and stress) and predicted QoL in various end-stage renal replacement therapy patients with ESRD.

METHODS

This cross-sectional study included HD or TX patients in the Eastern Region of Saudi Arabia. The 36-item Short Form Survey and Depression Anxiety Stress Scale (DASS) was used for data collection, and correlation and regression analyses were performed.

RESULTS

The HD and TX transplantation groups showed statistically significant inverse relationships between QoL and DASS scores. HD patients with high anxiety levels and less education scored low on the physical component summary (PCS). In addition, the results of the mental component summary (MCS) were associated with reduced depression. Compared with older transplant patients, TX patients' PCS scores were lower, and depression, stress, and negative working conditions were highly correlated with MCS scores.

CONCLUSION

The findings of this study revealed notable connections between well-being and mental turmoil experienced by individuals undergoing HD and TX. The PCS of HD patients is affected by heightened levels of anxiety and lower educational attainment, while the MCS of transplant patients is influenced by advancing age and elevated stress levels. These insights will contribute to a more comprehensive understanding of patient support.

Mediating role of inner strength in the relationship between medication literacy and medication adherence among kidney transplant patients

OBJECTIVES

Compared with long-term renal replacement therapy, kidney transplantation is the ideal treatment for end-stage renal disease (ESRD), significantly extending patient life and improving quality of life. Kidney transplant patients need to adhere to lifelong immunosuppressive medication regimens, but their medication adherence is generally poor compared with other organ transplant recipients. Medication adherence is closely related to medication literacy and psychological status, yet related studies are limited. This study aims to investigate the current status of medication adherence, inner strength, and medication literacy in kidney transplant patients, analyze the relationships among these 3 factors, and explore the mediating role of inner strength in the relationship between medication literacy and medication adherence.

METHODS

A cross-sectional survey was conducted from March to October 2023 involving 421 patients aged≥18 years who visited kidney transplantation outpatient clinics at 4 tertiary hospitals in Hunan Province. The inner strength, medication literacy, and medication adherence of kidney transplant patients were investigated using the Inner Strength Scale (ISS), the Chinese version of the Medication Literacy Assessment in Spanish and English (MedLitRxSE), and the Chinese version of the Morisky Medication Adherence Scale-8 (C-MMAS-8), respectively. Univariate analysis was performed to examine the effects of demographic and clinical data on medication adherence. Correlation analysis was conducted to explore the relationships among medication literacy, medication adherence, and inner strength. Significant variables from univariate and correlation analyses were further analyzed using multiple linear regression, and the mediating effect of inner strength was explored.

RESULTS

Among the 421 questionnaires collected, 408 were valid, with an effective rate of 96.91%. The scores of C-MMAS-8, MedLitRxSE, and ISS were 6.64±1.16, 100.63±14.67, and 8.47±4.03, respectively. Among the 408 patients, only 86 (21.08%) patients had a high level of medication adherence, whereas 230 (56.37%) patients had a medium level of medication adherence, and 92 (22.55%) patients had poor medication adherence. Univariate analysis indicated that the kidney transplant patients' age, marital status, education levels, years since their kidney transplant operation, number of hospitalizations after the kidney transplant, and adverse drug reactions showed significant differences in medication adherence (all P<0.05). Correlation analysis showed that inner strength positively correlated with both medication literacy (r=0.183, P<0.001) and medication adherence (r=0.201, P<0.001). Additionally, there was a positive correlation between medication adherence and medication literacy (r=0.236, P<0.001). Inner strength accounted for 13.22% of the total effect in the mediating role between medication literacy and medication adherence.

CONCLUSIONS

The level of medication adherence among kidney transplant patients needs improvement, and targeted intervention measures are essential. Inner strength mediates the relationship between medication literacy and medication adherence in these patients. Healthcare professionals should focus on enhancing medication literacy and supporting patients' inner strength to improve medication adherence.

Early Post-Transplant Adaptation Experience in Young and Middle-Aged People With Kidney Transplant in China: A Qualitative Study

BACKGROUND

Successful adaptation to post-transplantation life in patients who have undergone kidney transplants is crucial. The psychosocial needs of people with kidney transplants are closely related to the health of the transplanted kidney. If transplant recipients cannot adapt to the effects of the transplant, their physical and mental health will be seriously impaired.

OBJECTIVE

The purpose of this study was to explore the early post-transplant adaptation experience of young and middle-aged persons with kidney transplants in China based on the Roy adaptation model.

METHODS

A qualitative descriptive study was conducted using semi-structured interviews. Fifteen young and middle-aged persons with kidney transplant were recruited from a tertiary hospital in China between September 2022 and March 2023 through purposive sampling. Data were analyzed using a thematic analysis approach.

RESULTS

This study identified 4 themes: (1) "two-sided" changes in physiological functioning, (2) "dawn and darkness" (conflicting perceived emotions about the future), (3) role functioning adaptation conflict and impairment, and (4) social isolation and the challenges of coping.

CONCLUSIONS

This study found that early post-transplant adaptation in young and middle-aged people with kidney transplant included both positive and negative experiences, and these findings can provide new insights into research related to successful post-operative adaptation.
