The Perspectives of Patients on Health-Care for Co-Morbid Diabetes and Chronic Kidney Disease: A Qualitative Study

Background Multi-morbidity due to diabetes and chronic kidney disease (CKD) remains challenging for current health-systems, which focus on single diseases. As a first step toward health-care improvement, we explored the perspectives of patients and their carers on factors influencing the health-care of those with co-morbid diabetes and CKD. Methods In this qualitative study participants with co-morbid diabetes and CKD were purposively recruited using maximal variation sampling from 4 major tertiary health-services from 2 of Australia’s largest cities. Separate focus groups were conducted for patients with CKD stages 3, 4 and 5. Findings were triangulated with semi-structured interviews of carers of patients. Discussions were transcribed verbatim and thematically analysed. Results Twelve focus groups with 58 participants and 8 semi-structured interviews of carers were conducted. Factors influencing health-care of co-morbid diabetes and CKD grouped into patient and health service level factors. Key patient level factors identified were patient self-management, socio-economic situation, and adverse experiences related to co-morbid diabetes and CKD and its treatment. Key health service level factors were prevention and awareness of co-morbid diabetes and CKD, poor continuity and coordination of care, patient and carer empowerment, access and poor recognition of psychological co-morbidity. Health-service level factors varied according to CKD stage with poor continuity and coordination of care and patient and carer empowerment emphasized by participants with CKD stage 4 and 5, and access and poor recognition of psychological co-morbidity emphasised by participants with CKD stage 5 and carers. Conclusions According to patients and their carers the health-care of co-morbid diabetes and CKD may be improved via a preventive, patient-centred health-care model which promotes self-management and that has good access, continuity and coordination of care and identifies and manages psychological morbidity.

Defining the relationship between average glucose and HbA1c in patients with type 2 diabetes and chronic kidney disease

AIMS To examine the relationship between average glucose (AG) and HbA1c in patients with and without chronic kidney disease (CKD) and type 2 diabetes. MATERIALS AND METHODS 43 patients with diabetes and CKD (stages 3-5) with stable glycaemic control, and glucose-lowering and erythropoiesis stimulating agent (ESA) doses, were prospectively studied for 3 months and compared to 104 age-matched controls with diabetes, without CKD from the ADAG study. Over 3 months, AG was calculated from 7 to 8 point self-monitored blood glucose measurements (SMBG) and from continuous glucose monitoring (CGMS), and mean HbA1c was calculated from 4 measurements. AG and HbA1c relationships were determined using multivariable linear regression analyses. RESULTS The CKD and non-CKD groups were well matched for age and gender. Mean AG tended to be higher (p=0.08) but HbA1c levels were similar (p=0.68) in the CKD compared with non-CKD groups. A linear relationship between AG and HbA1c was observed irrespective of the presence and stage of CKD. The relationship was weaker in patients with stage 4-5 CKD (non-CKD R2=0.75, stage 3 CKD R2=0.79 and stage 4-5 CKD R2=0.34, all p<0.01). The inclusion of ESA use in the model rendered the effect of CKD stage insignificant (R2=0.67, p<0.01). CONCLUSIONS In patients with type 2 diabetes and CKD there is a linear relationship between HbA1c and AG that is attenuated by ESA use, suggesting that ESA results in a systematic underestimation of AG derived from HbA1c.

Self-management in patients with diabetes and chronic kidney disease is associated with incremental benefit in HRQOL

AIMS There is insufficient and inconsistent data regarding the association between diabetes self-management, the process of facilitating the knowledge, skill, and ability necessary for diabetes self-care, and health-related quality of life (HRQOL) in people with diabetes and moderate to severe chronic kidney disease (CKD). METHODS In a cross sectional study, participation in diabetes self-management assessed by the Summary of Diabetes Self-Care Activities (SDSCA) questionnaire and HRQOL was examined in 308 patients with diabetes and CKD (stages 3 to 5) recruited from outpatient diabetes and renal clinics of 4 public tertiary hospitals. Associations were examined by Pearson correlation coefficients and hierarchical multiple regression after controlling for potential confounders. An examination of trend across the levels of patient participation in self-management was assessed using a non-parametric test for trend. RESULTS The median age and interquartile range (IQR) of patients were 68 and 14.8years, respectively with 59% of the population being over 65years old and 69.5% male. The median durations of diabetes and CKD were 18years (IQR-17) and 5years (IQR-8) respectively. General diet, exercise and medication taking were positively associated with at least one HRQOL subscale (all p<0.05) but diabetes specific diet, blood sugar testing and foot checking were not. As levels of participation in self-management activities increased there was a graded increase in mean HRQOL scores across all subscales (p for trend <0.05). CONCLUSIONS In people with diabetes and moderate to severe CKD, participation in diabetes self-management activities, particularly those focused on general diet, exercise and medication taking, was associated with higher HRQOL.

The association between patient activation and self-care practices: A cross-sectional study of an Australian population with comorbid diabetes and chronic kidney disease

This study aimed to examine the association between performance of self‐care activities and patient or disease factors as well as patient activation levels in patients with diabetes and chronic kidney disease (CKD) in Australia.

Predictors of Health-Related Quality of Life in Patients with Co-Morbid Diabetes and Chronic Kidney Disease

Background People living with diabetes and chronic kidney disease (CKD) experience compromised quality of life. Consequently, it is critical to identify and understand factors influencing their health-related quality of life (HRQoL). This study examined factors associated with HRQoL among patients with diabetes and CKD. Methods A cross sectional study among adults with comorbid diabetes and CKD (eGFR <60 mL/min/1.73m2) recruited from renal and diabetes clinics of four large tertiary referral hospitals in Australia was performed. Each participant completed the Kidney Disease Quality of Life (KDQoL ™ -36) questionnaire, which is comprised of two composite measures of physical and mental health and 3 kidney disease specific subscales with possible scores ranging from 0 to 100 with higher values indicating better HRQoL. Demographic and clinical data were also collected. Regression analyses were performed to determine the relationship between HRQoL and potential predictor factors. Results A total of 308 patients were studied with a mean age of 66.9 (SD = 11.0) years and 70% were males. Mean scores for the physical composite summary, mental composite summary, symptom/problem list, effects of kidney disease and burden of kidney disease scales were 35.2, 47.0, 73.8, 72.5 and 59.8 respectively. Younger age was associated with lower scores in all subscales except for the physical composite summary. Female gender, obese or normal weight rather than overweight, and smoking were all associated with lower scores in one or more subscales. Scores were progressively lower with more advanced stage of CKD (p<0.05) in all subscales except for the mental composite summary. Conclusion In patients with diabetes and CKD, younger age was associated with lower scores in all HRQoL subscales except the physical composite summary and female gender, obese or normal weight and more advanced stages of CKD were associated with lower scores in one or more subscales. Identifying these factors will inform the timely implementation of interventions to improve the quality of life of these patients.

Primary and tertiary health professionals' views on the health-care of patients with co-morbid diabetes and chronic kidney disease - a qualitative study.

BackgroundHealth-care for co-morbid diabetes and chronic kidney disease (CKD) is often sub-optimal. To improve health-care, we explored the perspectives of general practitioners (GPs) and tertiary health-care professionals concerning key factors influencing health-care of diabetes and CKD.MethodsA total of 65 health professionals were purposively sampled from Australia’s 2 largest cities to participate in focus groups and semi-structured interviews. Four focus groups were conducted with GPs who referred to 4 tertiary health services in Australia’s 2 largest cities, with 6 focus groups conducted with tertiary health-care professionals from the 4 tertiary health services. An additional 8 semi-structured interviews were performed with specialist physicians who were heads of diabetes and renal units. All discussions were facilitated by the same researcher, with discussions digitally recorded and transcribed verbatim. All qualitative data was thematically analysed independently by 2 researchers.ResultsBoth GPs and tertiary health-care professionals emphasised the importance of primary care and that optimal health-care was an inter-play between patient self-management and primary health-care, with specialist tertiary health-care support. Patient self-management, access to specialty care, coordination of care and a preventive approach were identified as key factors that influence healthcare and require improvement. Both groups suggested that an integrated specialist diabetes-kidney service could improve care. Unit heads emphasised the importance of quality improvement activities.ConclusionsGPs and tertiary health-care professionals emphasised the importance of patient self-management and primary care involvement in the health-care of diabetes and CKD. Supporting GPs with an accessible, multidisciplinary diabetes-renal health service underpinned by strong communication pathways, a preventive approach and quality improvement activities, may improve health-care and patient outcomes in co-morbid diabetes and CKD.

Effectiveness of management models for facilitating self-management and patient outcomes in adults with diabetes and chronic kidney disease

BackgroundSelf-management models can be a very powerful resource in the health system provided they are well tailored to a particular disease and setting. Patient outcomes have been demonstrated to improve when self-management practices are embedded in the care of people with certain diseases. However, it remains unclear whether self-management models and specific components of these programmes can be implemented in order to effectively improve the care of people with diabetes and/or chronic kidney disease.Methods/DesignMedline (including Medline in-process), Excerpta medica database (EMBASE), Cumulative Index to Nursing and Allied Health (CINAHL) and all evidence-based medicine (EBM) will be systematically searched for randomised controlled studies comparing self-management models with usual care in patients with diabetes or chronic kidney disease. Two reviewers will independently assess articles for eligibility: extract data, evaluate risk of bias and complete quality assessment of included studies. The data will be tabulated and narratively synthesised. Meta-analyses will be performed if there is sufficient homogenous data.DiscussionThis protocol utilises rigorous methodology as well as pre-specified eligibility criteria to comprehensively search for diabetes and kidney disease self-management models which have been compared with usual care in randomised controlled trials. The review is likely to provide insight into the effectiveness of current models for improving patient self-management, and this may address the key translational issue of how to integrate and tailor these self-management practices for patients with diabetes and chronic kidney disease.Systematic review registrationPROSPERO CRD42015017316.

Factors associated with patient activation in an Australian population with comorbid diabetes and chronic kidney disease: a cross-sectional study

Objective To evaluate the extent of patient activation and factors associated with activation in adults with comorbid diabetes and chronic kidney disease (CKD). Design A cross-sectional study. Setting Renal/diabetes clinics of four tertiary hospitals across the two largest states of Australia. Study population Adult patients (over 18 years) with comorbid diabetes and CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2). Main outcome measures Patients completed the Patient Activation Measure, the Kidney Disease Quality of Life and demographic and clinical data survey from January to December 2014. Factors associated with patient activation were examined using χ2 or t-tests and linear regression. Results Three hundred and five patients with median age of 68 (IQR 14.8) years were studied. They were evenly distributed across socioeconomic groups, stage of kidney disease and duration of diabetes but not gender. Approximately 46% reported low activation. In patients with low activation, the symptom/problem list, burden of kidney disease subscale and mental composite subscale scores were all significantly lower (all p<0.05). On multivariable analysis, factors associated with lower activation for all patients were older age, worse self-reported health in the burden of kidney disease subscale and lower self-care scores. Additionally, in men, worse self-reported health in the mental composite subscale was associated with lower activation and in women, worse self-reported health scores in the symptom problem list and greater renal impairment were associated with lower activation. Conclusion Findings from this study suggest that levels of activation are low in patients with diabetes and CKD. Older age and worse self-reported health were associated with lower activation. This data may serve as the basis for the development of interventions needed to enhance activation and outcomes for patients with diabetes and CKD.

Intensive glucose control in patients with type 2 diabetes is associated with a reduction in albuminuria and may be associated with reduced end-stage renal disease

Commentary on: Coca SG, Ismail-Beigi F, Haq N, et al. Role of intensive glucose control in development of renal end points in type 2 diabetes mellitus: systematic review and meta-analysis intensive glucose control in type 2 diabetes. Ann Intern Med 2012; 172:761–9.[OpenUrl][1][CrossRef][2][Web of Science][3] Diabetic nephropathy is the commonest cause of end-stage renal disease (ESRD)1 making the prevention of its onset and progression, critically important. While epidemiological studies have linked hyperglycaemia to diabetic nephropathy, randomised controlled trials (RCTs) to date have reported the beneficial effects of intensive glycaemic control on early stages of nephropathy, that is, albuminuria levels but not ESRD. On the basis of this evidence, guidelines have recommended a glycated haemoglobin (HbA1c) of <7% to prevent renal outcomes. This systematic review specifically examines whether intensive glycaemic control improves a range of early and advanced renal outcomes in patients with type 2 diabetes (T2DM).

Evaluating optimal utilisation of technology in type 1 diabetes mellitus from a clinical and health economic perspective: protocol for a systematic review

BackgroundTechnology has been implemented since the 1970s with the hope of improving glycaemic control and reducing the burden of complications for those living with type 1 diabetes. A clinical and cost-effectiveness comparison of all available technologies including continuous subcutaneous insulin infusion (CSII), continuous glucose monitors (CGMs), sensor-augmented pump therapy (including either low-glucose suspend or predictive low-glucose suspend), hybrid closed-loop systems, closed-loop (single-hormone or dual-hormone) systems, flash glucose monitoring (FGM), insulin bolus calculators, and ‘smart-device’ applications is currently lacking. This systematic review, network meta-analysis, and narrative synthesis aims to summarise available evidence regarding the clinical and cost-effectiveness of available technologies in the management of patients with type 1 diabetes.MethodsRelevant studies will be searched using a comprehensive strategy through MEDLINE, MEDLINE in-process and other non-indexed citations, EMBASE, PubMed, all evidenced-based medicine reviews, EconLit, Cost-effectiveness Analysis Registry, Research Papers in Economics, Web of Science, PsycInfo, CINAHL, and PROSPERO for randomised controlled trials and economic evaluations. The search strategy will assess if there are combinations of currently available technologies that are superior to each other or to insulin injections and capillary blood glucose testing with regard to glycaemic control, morbidity/mortality, quality of life, and cost-effectiveness. Two reviewers will screen all articles for eligibility and then independently evaluate risk of bias, complete quality assessment, and extract data for included studies. Network meta-analyses will be performed where there is sufficient homogenous clinical data. Narrative synthesis will be performed for heterogeneous clinical data that cannot be pooled for network meta-analysis with critical appraisal of economic evaluations.DiscussionThis systematic review protocol utilises rigorous methodology and pre-determined eligibility criteria to provide a uniquely comprehensive search for a broad spectrum of clinical and economic outcomes in comparing multiple currently available technologies for managing type 1 diabetes. Evidence on which technologies may be most appropriate for particular patient groups will be examined as well as the economic justification for funding of different technologies.Systematic review registrationPROSPERO (CRD42017077221)
