Evaluation of a nurse-led disease management programme for chronic kidney disease: A randomized controlled trial

BACKGROUND Patients with end stage renal failure require dialysis and strict adherence to treatment plans to sustain life. However, non-adherence is a common and serious problem among patients with chronic kidney disease. There is a scarcity of studies in examining the effects of disease management programmes on patients with chronic kidney disease. OBJECTIVES This paper examines whether the study group receiving the disease management programme have better improvement than the control group, comparing outcomes at baseline (O1), at 7 weeks at the completion of the programme (O2) and at 13 weeks (O3). METHODS This is a randomized controlled trial. The outcome measures were non-adherence in diet, fluid, dialysis and medication, quality of life, satisfaction, symptom control, complication control and health service utilisation. RESULTS There was no significant difference between the control and study group for the baseline measures, except for sleep. Significant differences (p<0.05) were found between the control and study group at O2 in the outcome measures of diet degree non-adherence, sleep, symptom, staff encouragement, overall health and satisfaction. Sustained effects at O3 were noted in the outcome measures of continuous ambulatory peritoneal dialysis (CAPD) non-adherence degree, sleep, symptom, and effect of kidney disease. CONCLUSIONS Many studies exploring chronic disease management have neglected the group with end stage renal failure and this study fills this gap. This study has employed an innovative model of skill mix using specialist and general nurses and demonstrated patient improvement in diet non-adherence, CAPD non-adherence, aspects of quality of life and satisfaction with care. Redesigning chronic disease management programmes helps to optimize the use of different levels of skills and resources to bring about positive outcomes.

Comparison of effects between home visits with telephone calls and telephone calls only for transitional discharge support: a randomised controlled trial

Background: home visits and telephone calls are two often used approaches in transitional care but their differential effects are unknown. Objective: to examine the overall effects of a transitional care programme for discharged medical patients and the differential effects of telephone calls only. Design: randomised controlled trial. Setting: a regional hospital in Hong Kong. Participants: patients discharged from medical units fitting the inclusion criteria (n = 610) were randomly assigned to: control (‘control’, n = 210), home visits with calls (‘home’, n = 196) and calls only (‘call’, n = 204). Intervention: the home groups received alternative home visits and calls and the call groups calls only for 4 weeks. The control group received two placebo calls. The nurse case manager was supported by nursing students in delivering the interventions. Results: the home visit group (after 4 weeks 10.7%, after 12 weeks 21.4%) and the call group (11.8, 20.6%) had lower readmission rates than the control group (17.6, 25.7%). Significance differences were detected in intention-to-treat (ITT) analysis for the home and intervention group (home and call combined) at 4 weeks. In the per-protocol analysis (PPA) results, significant differences were found in all groups at 4 weeks. There was significant improvement in quality of life, self-efficacy and satisfaction in both ITT and PPA for the study groups. Conclusions: this study has found that bundled interventions involving both home visits and calls are more effective in reducing readmissions. Many of the transitional care programmes use all-qualified nurses, and this study reveals that a mixed skills model seems to bring about positive effects as well.

The impact and importance of clinical learning experience in supporting nursing students in end-of-life care: Cluster analysis

BACKGROUND Nursing students are often expected to provide end-of-life care to patients during clinical practice. Little research has been conducted to examine the heterogeneity of the students and how learning outcomes are affected by their education experience and other demographic factors. AIM The aim of this study was to identify and compare groups of nursing students based on their demographics, clinical experience, knowledge, perceived competency, and attitude towards end-of-life care. METHOD A group of 253 nursing students was asked to complete a cross-sectional survey to explore their clinical experience, knowledge, attitude, and perceived competency towards end-of-life care. Cluster analysis was used to determine whether specific groups of students could be identified within the study cohort. RESULTS Three distinct clusters were identified. Students from the three clusters showed no significant differences in end-of-life knowledge. Significant differences were identified in clinical experience amongst the three clusters and in attitude and perceived competency within the clusters. The cluster of students that had greater clinical experience demonstrated higher perceived competency and a more positive attitude towards end-of-life care. CONCLUSION Clinical experience was found to be crucial in enhancing the perceived competency and attitude of nursing students in end-of-life care.

Determining the validity and reliability of the Chinese version of the Kidney Disease Quality of Life Questionnaire (KDQOL-36™)

BackgroundHealth-related quality of life is a crucial outcome for the chronic kidney disease population, the Kidney Disease Quality of Life (KDQOL) questionnaire is commonly used as an integral part of clinical evaluations. The abbreviated version of the KDQOL-36™ has been translated into Mandarin Chinese, but has not been tested for use in the Chinese patients. The aim of the study was to evaluate the validity and reliability of the KDQOL-36™ with a sample of Chinese patients.MethodsThe Mandarin Chinese version of the KDQOL-36™ has been translated by Amgen, Inc. and the MAPI Institution following the instrument translation specifications provided by the RAND health. The translated instrument was further reviewed by a Chinese expert panel for content validity and translational equivalence. The KDQOL-36™ along with Beck depression Inventory-II were administrated to 103 chronic renal disease patients recruited through convenience sampling procedure from the renal wards and an outpatient dialysis clinic. The convergent validity was determined through investigating the correlational evidence of the KDQOL-36™ with the Beck depression Inventory-II and the overall health rating. Known-group validity was supported by the evidence that the instrument could differentiate subgroups of patients. The internal consistency was estimated using Cronbach’s α and test-retest reliability was examined using an intraclass correlation coefficient.ResultsFor the convergent validity, there were positive correlations between the overall health rating and most of the KDQOL-36™ subscales, and the Beck depression inventory score was inversely correlated with the mental component summary score and disease-specific scores of the scale. Significant correlations were noted between disease-targeted and generic dimensions of the KDQOL-36™. The results of the known-group comparisons indicated females, the unemployed, and patients had a longer dialysis history reported a worse quality of life. With regard to the reliability, the Cronbach’s alpha ranged from 0.69 to 0.78, and the intraclass correlation test-retest was higher than 0.70.ConclusionsThe Mandarin Chinese version of the KDQOL-36™ is a brief, valid, and reliable instrument for use in examining the quality of life of chronic kidney disease patients in China.

A randomized controlled trial of a nurse-led case management programme for hospital-discharged older adults with co-morbidities

Aim To examine the effects of a nurse-led case management programme for hospital-discharged older adults with co-morbidities. Background The most significant chronic conditions today involve diseases of the cardiovascular, respiratory, endocrine and renal systems. Previous studies have suggested that a nurse-led case management approach using either telephone follow-ups or home visits was able to improve clinical and patient outcomes for patients having a single, chronic disease, while the effects for older patients having at least two long-term conditions are unknown. A self-help programme using motivation and empowerment approaches is the framework of care in the study. Design Randomized controlled trial. Method The study was conducted from 2010–2012. Older patients having at least two chronic diseases were included for analysis. The participants were randomized into three arms: two study groups and one control group. Data were collected at baseline and at 4 and 12 weeks later. Results Two hundred and eighty-one patients completed the study. The interventions demonstrated significant differences in hospital readmission rates within 84 days post discharge. The two intervention groups had lower readmission rates than the control group. Patients in the two study arms had significantly better self-rated health and self-efficacy. There was significant difference between the groups in the physical composite score, but no significant difference in mental component score in SF-36 scale. Conclusion The postdischarge interventions led by the nurse case managers on self-management of disease using the empowerment approach were able to provide effective clinical and patient outcomes for older patients having co-morbidities.

A nurse-led case management program on home exercise training for hemodialysis patients: A randomized controlled trial

BACKGROUND Patients on maintenance hemodialysis suffer from diminished physical health. Directly supervised exercise programs have been shown to be effective at improving physical function and optimizing well-being. However, nurses seldom include an exercise intervention in the care plan for hemodialysis patients. OBJECTIVES The purpose of this study was to examine the effects of a 12-week nurse-led case management program on home exercise training for hemodialysis patients. DESIGN The study was a randomized, two-parallel group trial. SETTINGS Hemodialysis units in two tertiary hospitals in Nanjing, mainland China. PARTICIPANTS One hundred and thirteen adult patients who have been in stable condition while on dialysis treatment for more than 3 months were recruited and randomly assigned to either the study group (n=57) or the control group (n=56). METHODS Both groups underwent a brief weekly in-center exercise training session before their dialysis sessions for the first 6 weeks. The study group received additional nurse case management weekly for the first 6 weeks and biweekly for the following 6 weeks. The intervention was to facilitate patients in performing regular exercise at home. Outcome measures, including gait speed, 10-repetition sit-to-stand performance, and quality of life were collected at baseline, and at 6 and 12 weeks into the program. RESULTS The results revealed that patients in the study group demonstrated greater increases in normal gait speed [F(1,111)=4.42, p=0.038] than the control group. For the study group, a mean increase of 12.02 (±3.03)centimeters/second from baseline to week 12 was found. With regard to the fast gait speed, there was a marginally significant between-group effect [F(1,111)=3.93, p=0.050]. The study group showed a mean improvement of 11.08 (±3.32)cm/s, from baseline to week 12. Patients from both groups showed improvements in their 10-repetition sit-to-stand performance. The between-group differences approached significance [F(1,111)=3.92, p=0.050], with the study group showed greater improvement than the control group. The time taken by the patients in the study group to complete the 10-STS test increased by 5.75 (±3.88)s from baseline to week 12. Significant improvements in quality of life across three time points were found only in the study group. CONCLUSIONS Home exercise using a nurse-led case management approach is practical and effective in improving the physical function and self-perceived health of stable hemodialysis patients.

Is the kidney disease quality of life-36 (KDQOL-36) a valid instrument for Chinese dialysis patients?

BackgroundThe aim of this study is to determine the validity and reliability of the Cantonese Chinese version of the Kidney Disease Quality of Life-36 (KDQOL-36™) questionnaire. The scale has been translated into Cantonese Chinese, but has not been tested among the Cantonese-speaking populations.MethodsA total of 110 dialysis patients and 122 renal transplant patients were recruited. The data for the KDQOL-36™ were extracted from the KDQOL-Short Form. The criterion validity and scale equivalence were examined using the KDQOL-Short Form scores as the gold standard. The Hospital Anxiety and Depression scale was used to identify the correlations between depression, anxiety, and quality of life to establish the convergent validity. Discriminant validity was examined using the transplant patients to compare the quality of life of dialysis patients. The Cronbach’s alpha coefficient and test-retest were used for estimating reliability.ResultsThere were very strong positive correlations for the physical and mental component summary between the KDQOL-36™ and KDQOL-Short Form. Despite the strong correlations, the effect size was 0.6 and 0.13 for the physical composite summary and mental composite summary score, respectively. Most of the subscales demonstrated significant moderate correlations with the Hospital Anxiety and Depression Scale, from -0.265 to -0.516. The discriminant validity was confirmed with a significant difference between the dialysis and transplant group patients. A high intraclass correlation of >0.98 was demonstrated in the test-retest.ConclusionThe Cantonese Chinese KDQOL-36™ was reliable. Further testing will be required to determine its validity for the physical health summary scale.

The Effect of a Restraint Reduction Program on Physical Restraint Rates in Rehabilitation Settings in Hong Kong

Background. In view of the adverse effects of using restraints, studies examining the use of restraint reduction programs (RRPs) are needed. Objectives. To investigate the effect of an RRP on the reduction of physical restraint rates in rehabilitation hospitals. Methods. A prospective quasi-experimental clinical trial was conducted. Demographic data, medical and health-related information on recruited patients from two rehabilitation hospitals, as well as facility data on restraint rates were collected. Results. The increase in the restraint rate in the control site was 4.3 times greater than that in the intervention site. Changes in the restraint mode, from continuous to intermittent, and the type of restraint used were found between the pre- and postintervention periods in both the control site and the intervention site. Discussion. Compared with that in the control site, the RRP in the intervention site helped arrest any increase in the restraint rate although it had no effect on physical restraint reduction. The shift of restraint mode from continuous to intermittent in the intervention site was one of the positive outcomes of the RRP.

Knowledge and Misconceptions on Cardiovascular Disease among Nursing Students

According to Centers for Disease Control and Prevention, Coronary artery disease is the most common type of heart disease in the United States. Nurse educators should evaluate the cardiac knowledge and misconceptions of the nursing students to ensure they are disseminating accurate information in their future practice. There were 362 Hong Kong nursing students participated in the study. The results showed that the scores for the nursing students’ level of knowledge were diverse. A negative correlation, r=-0.33 was found among students with more knowledge and fewer misconceptions. (p<0.001). The Chisquare tests found some associations between the students’ experiences of caring for cardiac patients and misconceptions about stress and physiology. A new paradigm of teaching should include inputs from both perspectives to help students to make critical use of theoretical knowledge to rectify their misconceptions and pursue excellence in the working world.
