The Effects of Interventions on Health-Related Quality of Life Among Persons With Diabetes

Somatic and mental symptoms associated with dysglycaemia, diabetes-related complications and mental conditions in people with diabetes: Assessments in daily life using continuous glucose monitoring and ecological momentary assessment

AIM

To analyse the potential drivers (glucose level, complications, diabetes type, gender, age and mental health) of diabetes symptoms using continuous glucose monitoring (CGM) and ecological momentary assessment.

MATERIALS AND METHODS

Participants used a smartphone application to rate 25 diabetes symptoms in their daily lives over 8 days. These symptoms were grouped into four blocks so that each symptom was rated six times on 2 days (noon, afternoon and evening). The symptom ratings were associated with the glucose levels for the previous 2 hours, measured with CGM. Linear mixed-effects models were used, allowing for nested random effects and the conduct of N = 1 analysis of individual associations.

RESULTS

In total, 192 individuals with type 1 diabetes and 179 with type 2 diabetes completed 6380 app check-ins. Four symptoms showed a significant negative association with glucose values, indicating higher ratings at lower glucose (speech difficulties, P = .003; coordination problems, P = .00005; confusion, P = .049; and food cravings, P = .0003). Four symptoms showed a significant positive association with glucose values, indicating higher scores at higher glucose (thirst, P = .0001; urination, P = .0003; taste disturbances, P = .021; and itching, P = .0120). There were also significant positive associations between microangiopathy and eight symptoms. Elevated depression and diabetes distress were associated with higher symptom scores. N = 1 analysis showed highly idiosyncratic associations between symptom reports and glucose levels.

CONCLUSIONS

The N = 1 analysis facilitated the creation of personalized symptom profiles related to glucose levels with consideration of factors such as complications, gender, body mass index, depression and diabetes distress. This approach can enhance precision monitoring for diabetes symptoms in precision medicine.

Effect of islet alone or islets after kidney transplantation on quality of life in type 1 diabetes: A systematic review

BACKGROUND

Pancreatic islet transplantation for type 1 diabetes mellitus (T1DM) is efficacious in supressing severe hypoglycaemic episodes (SHE) and restoring glycaemic regulation, which are both pivotal in increasing health-related quality of life (HRQoL). Therefore, a systematic assessment of reports detailing HRQoL outcomes is warranted to better understand the benefits of islet transplantation. To this end, we performed a systematic review of the literature to assess the impact of islet transplantation on HRQoL in individuals with T1DM, whether as a standalone procedure (ITA) or following renal transplantation (IAK).

METHOD

All studies providing a quantitative assessment of HRQoL following ITA or IAK were included. Selected studies had to meet the following criteria: they had to (i) involve adult recipients of islet grafts for T1DM, (ii) use either generic or disease-specific QoL assessment tools, (iii) provide a comparative analysis of QoL metrics between the pre- and post-transplantation state or between the post-transplantation state and other pre-transplant patients or the general population.

RESULTS

Seven studies that met the inclusion criteria provided data on 205 subjects. In the included studies, HRQoL was measured using both generic instruments, such as the 36-item Short Form Health Survey (SF-36) and the Health Status Questionnaire (HSQ) 2.0, and disease-specific instruments, such as the Diabetes Distress Scale (DDS), the Diabetes Quality of Life Questionnaire, and the Hypoglycaemia Fear Survey (HFS). These instruments cover physical, mental, social, or functional health dimensions. We found that pancreatic islet transplantation was associated with improvements in all HRQoL dimensions compared with the pre-transplant baseline.

CONCLUSIONS

Our systematic review demonstrates that islet transplantation significantly enhances quality of life in individuals with T1DM who are experiencing SHE. To our knowledge, this is the most extensive systematic review conducted to date, evaluating the impact of islet transplantation on HRQoL.

Sex-driven factors associated with anxiety and depression in autoimmune diabetes

AIM

To analyze the prevalence of anxiety and depression in a large cohort of adults with autoimmune diabetes, identifying sex-driven associated factors.

MATERIALS AND METHODS

In this cross-sectional study, we enrolled 553 consecutive adults with Type 1 diabetes mellitus or latent autoimmune diabetes in adults who came to the Division of Endocrinology of the S.Orsola-Malpighi Polyclinic, Bologna (Italy), to receive their second dose of SARS-CoV-2 vaccine. We administered the questionnaires: Hospital Anxiety and Depression Scale, Diabetes Distress Scale, Diabetes-related Quality of Life, Diabetes Treatment Satisfaction Questionnaire. We collected clinical and biochemical data and 14 days glucose metrics in patients with sensor use > 70% in a time span of ± 4 months from the questionnaires' administration. We excluded 119 patients from our analyses with missing data (final cohort n = 434: 79% of those enrolled).

RESULTS

Anxiety and depression prevalence was respectively 30.4% and 10.8%. According to the multivariate analysis, higher diabete-related emotional burden, lower treatment satisfaction, but not physician-related distress, were risk factors for anxiety and depression; female sex was associated with anxiety (OR 0.51, 95% 0.31-0.81; p = 0.005); in women, depression was associated with increasing age (males vs. females OR 0.96 per 1 year increase, 95% CI 0.92-1.00; p = 0.036), whilst in men with HbA1c (OR 1.08 per 1 mmol/mol increase, 95% CI 1.03-1.13; p = 0.002).

CONCLUSION

Nearly 1/3 of patients with autoimmune diabetes suffers from anxiety and 1/10 from depression. These conditions are associated with independent modifiable and non-modifiable characteristics. For depression, these characteristics differ between males and females.

The effectiveness of diabetes self-management education intervention on glycaemic control and cardiometabolic risk in adults with type 2 diabetes in low- and middle-income countries: A systematic review and meta-analysis

Diabetes mellitus (DM) poses a significant challenge to public health. Effective diabetes self-management education (DSME) interventions may play a pivotal role in the care of people with type 2 diabetes mellitus (T2DM) in low- and middle-income countries (LMICs). A specific up-to-date systematic review is needed to assess the effect of DSME interventions on glycaemic control, cardiometabolic risk, self-management behaviours, and psychosocial well-being among T2DM across LMICs. The MEDLINE, Embase, CINAHL, Global Health, and Cochrane databases were searched on 02 August 2022 and then updated on 10 November 2023 for published randomised controlled trials (RCTs) and quasi-experimental studies. The quality of the studies was assessed, and a random-effect model was used to estimate the pooled effect of diabetes DSME intervention. Heterogeneity (I2) was tested, and subgroup analyses were performed. Egger's regression test and funnel plots were used to examine publication bias. The risk of bias of the included studies was assessed using the Cochrane risk-of-bias tool for randomized trial (RoB 2). The overall assessment of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation approach. A total of 5893 articles were retrieved, and 44 studies (n = 11838) from 21 LMICs met the inclusion criteria. Compared with standard care, pooled analysis showed that DSME effectively reduced the HbA1c level by 0.64% (95% CI: 0.45% to 0.83%) and 1.27% (95% CI: -0.63% to 3.17%) for RCTs and quasi-experimental design studies, respectively. Further, the findings showed an improvement in cardiometabolic risk reduction, diabetes self-management behaviours, and psychosocial well-being. This review suggests that ongoing support alongside individualised face-to-face intervention delivery is favourable for improving overall T2DM management in LMICs, with a special emphasis on countries in the lowest income group.

A multidisciplinary, shared care clinic using personalized medicine and coordinated care in patients with concomitant type 2 diabetes and cardiovascular disease. Protocol and baseline characteristics

Background

Concomitant type 2 diabetes (T2DM) and cardiovascular disease (CVD) is frequent with a poor prognosis with high risk of comorbidities. Strict risk factor control reduces the risk for complications - yet many people do not achieve treatment targets. The complexity and fragmentation of the healthcare system may, together with the vulnerability of these patients, be a reason.

Objective

The purpose of this paper is to describe the protocol of a non-randomized interventional pilot study testing the feasibility and effect of a multidisciplinary, shared care clinic using personalized medicine and coordinated care in people living with concomitant T2D and CVD.

Methods

Participants were included from the Holbaek area in Denmark. People suffered from T2DM and CVD and were dysregulated regarding to HbA1c, cholesterol, micro/macroalbuminuaria or blood pressure. Participants went through a thorough evaluation to identify their needs and resources and received consultations every three months for one year.

Results

A total of 63 participants with T2DM and CVD were enrolled in the clinic. The participants had a mean age of 69 years and a BMI of 30.9 kg/m2. Almost 50 % had heart failure, 95 % dyslipidemia and 91 % hypertension. Around 54 % received GLP-1 agonists and 39 % received SGLT-2-inhibitors.

Perspectives

To our knowledge, a similar study with a multidisciplinary, shared care, outpatient clinic treating people living with concomitant T2DM and CVD, has not been performed previously. This study will provide information about the feasibility and efficacy of a multidisciplinary clinic based on changes in cardiovascular risk factors and medication.

The effect of health behavior interventions to manage Type 2 diabetes on the quality of life in low-and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Behavioral interventions targeted at managing Type 2 diabetes mellitus (T2DM) may have a positive effect on quality of life (QOL). Limited reviews have synthesized this effect in low- and middle-income countries (LMICs). This review and meta-analysis synthesised available evidence on the effect of behavioral interventions to manage T2DM on the QOL of people with T2DM in LMICs.

METHODS

Electronic databases PUBMED/MEDLINE, SCOPUS, CINAHL, Embase, Web of Science and PsycINFO were searched from May to June 2022. Studies published between January 2000 and May 2022, conducted in LMICs using randomized controlled trial design, using a health behavior intervention for T2DM management, and reporting QOL outcomes were included. Difference in QOL change scores between the intervention and control group was calculated as the standardized mean difference (SMD) of QOL scores observed between the intervention and control groups. Random-effects model was used for meta-analysis.

RESULTS

Of 6122 studies identified initially, 45 studies met the inclusion criteria (n = 8336). Of them, 31 involved diabetes self-management education and 14 included dietary and/or physical activity intervention. There was moderate quality evidence from the meta-analysis of mean QOL (n = 25) that health behavior intervention improved the QOL of people with T2DM (SMD = 1.62, 95%CI = 0.65-2.60 I2 = 0.96, p = 0.001). However, no significant improvements were found for studies (n = 7) separately assessing the physical component summary (SMD = 0.76, 95%CI = -0.03-1.56 I2 = 0.94, p = 0.060) and mental component summary (SMD = 0.43, 95%CI = -0.30-1.16 I2 = 0.94, p = 0.249) scores. High heterogeneity and imprecise results across studies resulted in low to moderate quality of evidence.

CONCLUSION

The findings suggest that health behavior interventions to manage T2DM may substantially improve the QOL of individuals with T2DM over short term. However, due to low to moderate quality of evidence, further research is required to corroborate our findings. Results of this review may guide future research and have policy implications for T2DM management in LMICs.

Changes of health-related quality of life after initiating basal insulin treatment among people with type 2 diabetes

To assess the association between insulin regimens and health-related quality of life (HRQoL) after the introduction of basal insulin (BI) among people with type 2 diabetes in real-world clinical settings. 16,339 registered people with diabetes who had inadequate glycaemic control by oral agents initiated BI (either single BI or Basal-bolus) and completed a 6-month follow-up from 209 hospitals were included in the analyses. At the end of the follow-up, the switches of insulin regimens, change of HRQoL (EQ-5D-3L) and their associations were assessed. Initial insulin regimens of single BI and of basal-bolus (BI included Glargine, Detemir, and Neutral Protamine Hagedorn) accounted for 75.6% and 24.4%, respectively. At 6 months, regimens used were BI alone (65.2%), basal-bolus (10.4%), and premixed (6.4%), whereas 17.9% stopped all insulin therapy. The visual analogue scale score increased by 5.46 (P < .001), and the index value increased slightly by 0.02 (P < .001). Univariate analysis showed that people with diabetes taking basal-bolus regimen had the greatest improvement on HRQoL in all dimensions, especially in the reduction of the percentage of Pain/Discomfort (by 10.03%) and Anxiety/Depression (by 11.21%). In multivariable analysis, single BI or premixed insulin at 6 months was associated with more improvement of visual analogue scale score compared with stopping all insulin. Improved HRQoL was observed after initiating BI in people with type 2 diabetes . If the same achievement on HbA1c control can be guaranteed, single BI is preferred to other regimens from the viewpoint of HRQoL. Basal-bolus has the most significant potential to increase HRQoL, however, the people with diabetes characteristics differ from those initiating BI alone. Further longitudinal cohort study with a longer study period might be necessary to evaluate the certain effect.

The role of sense of community in improving the health-related quality of life among Black Americans

Black Americans have the lowest life expectancy and health-related quality of life (HRQoL; a strong predictor of premature mortality) of any racial/ethnic group in the United States. Low rates of physical activity and engagement in healthy eating are two known contributors to low HRQoL. Black Americans are more likely to live in environments that inhibit engagement in these two contributors. The present study examined sense of community as a buffer against the adverse effects of low physical activity and healthy eating on HRQoL among Black Americans. A sample of 290 Black American adults were recruited for the present study. Results indicate that sense of community buffers against the adverse effects of low physical activity on HRQoL. The results of the present study can be used by health promotion interventionists and policy-makers to improve HRQoL and reduce premature mortality among Black Americans.

Predictors of Health-Related Quality of Life Among African American Men

African American men have the lowest life expectancy of any ethnic gender group in the USA. Furthermore, these men endorse having a lower health-related quality of life (HRQoL) than any other group. There have been recent calls from national organizations to improve HRQoL-a multidimensional indicator of health strongly associated with mortality and morbidity. Following these calls, there have been widespread efforts implemented to improve HRQoL among the US population, though no known effort has been implemented that is tailored to the unique experiences of African American men. Health promotion efforts that are not tailored to the unique preferences and experiences of these men are likely to produce limited results. Formative research conducted among African American men is needed in order to design and implement an effective HRQoL-promoting intervention for African American men. The present study constitutes such formative research and was conducted with a sample of 211 African American men. Hierarchical regressions were performed to understand the role of literature-derived predictors of HRQoL among these men. Results found that depression, stress, and physical activity were found to be significant predictors of HRQoL among these men. This is the first known study to examine predictors of HRQoL among African American men-a group that disproportionately experiences health disparities and low HRQoL, though for who few successful health promotions exist. The findings from this study have implications for those seeking to design and implement HRQoL-promoting interventions among African American men.

Effects of Metabolic Medicine and Metabolic Surgery on Patient-Reported Outcomes Among Patients with Type 2 Diabetes

The assessment and management of patient-reported outcomes (PROs) is considered secondary to that of cardiometabolic outcomes. When assessed, health-related quality of life (HRQOL), a PRO, can yield pertinent information that cannot be obtained from cardiometabolic assessments. For instance, physical and mental distress can be quantified and treated. Moreover, treatment convenience and satisfaction can be gaged. Behavioral modification, bariatric surgery, and pharmacotherapy can improve PROs. Typically, HRQOL is responsive to changes in weight. Specifically, weight loss and weight gain are associated with positive and negative changes in quality of life, respectively. In addition, patient satisfaction can be influenced by glycemic control. Therefore, hypoglycemia and hyperglycemic episodes can negatively affect patient satisfaction. When managing type 2 diabetes (T2D), it is important to consider how therapies impact PROs. Generally, changes in clinical outcomes mirror changes in PROs. To best manage T2D, integrating the assessment of PROs with clinical outcomes is needed.

Cost-effectiveness analysis of infected necrotizing pancreatitis management in an academic setting

BACKGROUND AND AIMS

Traditional management for infected necrotizing pancreatitis (INP) often utilizes open necrosectomy, which carries high morbidity and complication rates. Thus, minimally invasive strategies have gained favor, specifically step-up approaches utilizing endoscopic or minimally-invasive surgery (MIS); however, the ideal management modality for INP has not been identified.

METHODS

A decision tree model was designed to analyze costs and survival associated with open necrosectomy, endoscopic step-up, and MIS step-up protocols for management of INP after 4 weeks of necrosis development with adequate retroperitoneal access. Costs were based on a third-party payer perspective using Medicare reimbursement rates. The model's effectiveness was represented by quality-adjusted life-years (QALYs). Sensitivity analyses were performed to validate results.

RESULTS

Endoscopic step-up was the dominant economic strategy with 7.92 QALYs for $90,864.09. Surgical step-up resulted in a decrease of 0.09 QALYs and a cost increase of $10,067.89 while open necrosectomy resulted in a decrease of 0.4 QALYs and an increased cost of $18,407.52 over endoscopic step-up. In 100,000 random-sampling simulations, 65.5% of simulations favored endoscopic step-up. MIS step-up was favored when MIS acute mortality rates fell and when MIS drainage success rates rose.

CONCLUSIONS

In our simulated patients with INP, the most cost-effective management strategy is endoscopic step-up. Cost-effectiveness varies with changes in acute mortality and drainage success, which will depend on local expertise.

Influences of Demographic, Social Determinants, Clinical, Knowledge, and Self-Care Factors on Quality of Life in Adults With Type 2 Diabetes: Black-White Differences

BACKGROUND

This study evaluated racial differences in the contribution of demographic, social determinants, clinical, and self-care factors on quality of life (QOL) in adults with type 2 diabetes mellitus (T2DM).

METHODS

A total of 615 adults with T2DM in Southeastern United States were recruited. Linear regression models were used to assess the contribution of demographic, social determinants, clinical, and self-care factors on the mental (MCS) and physical components (PCS) of QOL, after stratifying by race.

RESULTS

For the entire sample, there were significant relationships between PCS and psychological distress (β = 0.02, p < 0.01), neighborhood aesthetics (β = 0.05, p < 0.01), neighborhood walking environment (β = -0.02, p < 0.05), access to healthy food (β = 0.01, p < 0.05), neighborhood crime (β = -0.15, p < 0.05), and neighborhood comparison (β = 0.13, p < 0.05); and MCS and depression (β = -0.06, p < 0.05), psychological distress (β = -0.09, p < 0.001), perceived stress (β = -0.12, p < 0.01), and perceived health status (β = -0.33, p < 0.01). In the regression models stratified by race, notable differences existed in the association between PCS, MCS, and demographic, psychosocial, built environment, and clinical factors among Whites and Blacks, respectively.

CONCLUSION

In this sample, there were racial differences in demographic, social determinants, built environment, and clinical factors associated with PCS and MCS components of QOL. Interventions may need to be tailored by race or ethnicity to improve quality of life in adults with T2DM.

Parental understanding of relapsing idiopathic nephrotic syndrome-Where are the knowledge gaps?

AIM

To assess parental understanding of idiopathic nephrotic syndrome (INS) and its management, to enable targeted education in areas of deficit.

METHODS

Families of children with at least one relapse of INS were interviewed, following a template covering key domains of (a) disease understanding, (b) management of INS and (c) access to information. Common trends and responses were identified and notable observations recorded.

RESULTS

Twenty-one parents were interviewed. The mean duration of INS was 4.4 years (range 0.5-14.5 years), with a mean of two steroid-sparing agents used. Although 90% parents self-reported that they understood INS, only 29% could appropriately define relapse and 24% name potential complications. The management of INS was generally good, with most parents appropriately testing urine (81%) and managing relapses (90%). Unnecessary dietary restrictions were imposed on 57% during remission. The Internet was searched by 90% of parents for disease and drug information. Further information was desired in paper form (71%), hospital website (81%) and face-to-face workshop (90%), plus educational materials for schools.

CONCLUSION

Parents overestimated their understanding of INS; however, their management was generally well done. Parents desired more information and support in various forms.

Diabetic patient assessment of chronic illness care using PACIC

BACKGROUND

The Patient Assessment of Chronic Illness Care plus is used in order to assess whether provided care is congruent with the Chronic Care Model, according to patients. The purpose of this study was to correlate PACIC+ and the revised 5As "ask, advise, agree, assist and arrange" scoring of a sample of DM patients, with their QoL, depressive symptomatology, demographic and disease characteristics, self-management behaviours of healthy eating and physical activity.

METHODS

This is a cross-sectional study where data were collected between January and April 2018 by using three questionnaires (PACIC+, SF-36, CES-D) from a sample of 90 DM patients treated at a Public General Hospital of Central Greece. Anonymous self-completed questionnaires were used to collect the data. Data was processed in the Statistical Package for the Social Sciences (SPSS).

RESULTS

The mean age of the participants with DM was 52.8 years (SD = 21.2 years), with cardiovascular disease and arterial hypertension scoring as the most frequently reporting chronic comorbidities. The healthcare received by DM patients has been correlated with their QoL. More specifically SF - 36 and PACIC+ scale scores showed a positive and low correlation in several subscales. The total score of PACIC+ scale as well as the Patient activation score were increased in higher scores of vitality (p = 0.034 & p = 0.028 respectively), hence both scores correlate significantly with latter. In addition, Delivery System / Practice Design score was increased in higher scores of mental health (p = 0.01) and MCS (p = 0.03).

CONCLUSIONS

The shift from hospital care focusing on the disease to a more patient-oriented approach puts forward a dynamic holistic approach to chronic diseases and the reduction of their impact. Finding evidence-based and effective strategies to promote health, prevent and manage chronic diseases such as diabetes mellitus is deemed to be crucial and necessary. PACIC+, which is a tool of a patient-level assessment of CCM implementation, can be used by countries which intend to apply changes in the way their health systems provide chronic care and specifically wish to improve the quality of chronic disease care and the QoL of their patients.

Global Mapping of Interventions to Improve Quality of Life of People with Diabetes in 1990-2018

Improving the quality of life (QOL) of people living with diabetes is the ultimate goal of diabetes care. This study provides a quantitative overview of global research on interventions aiming to improve QOL among people with diabetes. A total of 700 English peer-reviewed papers published during 1990-2018 were collected and extracted from the Web of Science databases. Latent Dirichlet Allocation (LDA) analysis was undertaken to categorize papers by topic or theme. Results showed an increase in interventions to improve the QOL of patients with diabetes across the time period, with major contributions from high-income countries. Community- and family-based interventions, including those focused on lifestyle and utilizing digital technologies, were common approaches. Interventions that addressed comorbidities in people with diabetes also increased. Our findings emphasize the necessity of translating the evidence from clinical interventions to community interventions. In addition, they underline the importance of developing collaborative research between developed and developing countries.

[Quality of Life and Satisfaction During the Diabetes Prevention Program GLICEMIA: a Cluster-Randomized, Controlled Trial]

OBJECTIVES

We aimed to assess the health-related quality of life as well as participant satisfaction during the pharmacy-based diabetes prevention program GLICEMIA.

METHODS

GLICEMIA comprises 3 individual counseling sessions and 5 group-based lectures addressing a lifestyle modification. In a cluster-randomized controlled trial, GLICEMIA was compared with reduced standard information in the control group. After 12 months, the groups were compared regarding the diabetes risk score FINDRISC, health-related quality of life with the 12-item Short Form health survey (SF-12) and participant satisfaction.

RESULTS

In total, the data of 1,087 participants were analyzed. During GLICEMIA, 38.9% reduced their FINDRISC whereas 20.9% reached this goal in the control group. Moreover, the physical quality of life improved significantly in the intervention group compared with the control group (adjusted effect size: 2.39 points, 95% CI 1.43-3.34). Participants of GLICEMIA who reduced their diabetes risk had enhanced mental and physical quality of life after one year. This was not observed in the control group. The overall benefit and satisfaction were rated very high in the intervention group.

CONCLUSION

Participation in GLICEMIA results in a significant reduction of the diabetes risk according to the FINDRISC, as well as an improved physical and mental quality of life. The high satisfaction of the participants reflects the overall benefit. Nationwide implementation of the program is recommended.

National rates of emergency department visits associated with diabetes in Saudi Arabia, 2011-2015

BACKGROUND

Despite the fact that diabetes is an important component of the burden of disease on the individual and on the national healthcare systems in Saudi Arabia, knowledge of the volume of emergency department (ED) visits for diabetes is unclear.

OBJECTIVE

Examine changes in ED visit rates associated with diabetes.

DESIGN

Retrospective.

SETTINGS

Governmental hospitals.

METHODS

Publicly available records of health statistics published by the Saudi Ministry of Health from 2011 through 2015 were used to extract data on ED visits related to diabetes. ED visits associated with diabetes were compared over time and by gender. We calculated diabetes-specific rates per 10000 persons for each sex category by dividing the total number of diabetes-associated ED visits in that category by the sex-specific population. We calculated the rate difference (RD) with 95% CI between 2011 and 2015.

MAIN OUTCOME MEASURES

Diabetes-specific rates per 10000 persons for each sex category.

RESULTS

Total annual visits to the ED for management of diabetes increased from 617683 cases in 2011 to 748605 in 2015. The annual number of ED visits associated with diabetes increased by 21% over the study period (20% for males and 23% for females). Compared to males, females had a larger increase in visit rates from 240.5 to 249.8 visits per 10000 women over the study years (RD, 9.6 per 10000 persons, 95% CI -16.4 to 26.6 versus 5.7 per 10 000 persons, 95% CI-13.6 to 18.3 ; P=.01).

CONCLUSION

Although diabetes-associated ED visit rates dramatically increased in 2012, they remained relatively stable after 2012 to the end of the study period. More effective preventive diabetes programs that prevent the use of ED visits and other expensive healthcare resources among people with diabetes are needed.

LIMITATIONS

We had no information on the specific indications for the reported ED visits. These estimates may represent a lower bound on ED visits associated with diabetes since the private sector was not included.

CONFLICT OF INTEREST

None.

Effectiveness of the Chronic Care Model in Type 2 Diabetes Management in a Community Health Service Center in China: A Group Randomized Experimental Study

OBJECTIVE

The Chronic Care Model, based on core elements of team-centered care in chronic diseases, has widely been accepted. This study was aimed at evaluating the effectiveness of the Chronic Care Model in type 2 diabetes management.

METHODS

A group randomized experimental study was conducted. Twelve communities of the Zhaohui Community Health Service Center in Hangzhou, China, were randomly assigned into an intervention group (n = 6) receiving the Chronic Care Model-based intervention and a control group (n = 6) receiving conventional care. A total of three hundred patients, twenty-five for each community, aged ≥18 years with type 2 diabetes for at least 1-year duration, were recruited. Data of health behaviors, clinical outcomes, and health-related quality of life (Short-Form 36-item questionnaire) were collected before and after a 9-month intervention and analyzed using descriptive statistics, t-test, chi-square test, binary logistic regression, and linear mixed regression. A total of 258 patients (134 in intervention and 124 in control) who completed the baseline and follow-up evaluations and the entire intervention were included in the final analyses.

RESULTS

Health behaviors such as drinking habit (OR = 0.07, 95% CI: 0.01, 0.75), physical activity (OR = 2.92, 95% CI: 1.18, 7.25), and diet habit (OR = 4.30, 95% CI: 1.49, 12.43) were improved. The intervention group had a remarkable reduction in glycated hemoglobin (from 7.17% to 6.60%, P < 0.001). The quality of life score changes of the role limitation due to physical problems (mean = 9.97, 95% CI: 3.33, 16.60), social functioning (mean = 6.50, 95% CI: 2.37, 10.64), role limitation due to emotional problems (mean = 8.06, 95% CI: 2.15, 13.96), and physical component summary score (mean = 3.31, 95% CI: 1.22, 5.39) were improved in the intervention group compared to the control group.

CONCLUSION

The Chronic Care Model-based intervention helped improve some health behaviors, clinical outcomes, and quality of life of type 2 diabetes patients in China in a short term.

Association Between the Rate of Diabetes and Quality of Patient Care in Home Health Agencies

The multitude of comorbidities and disabilities that are prevalent among diabetic patients make their care very challenging for providers. This, in turn, may have a negative effect on measures of patient satisfaction, quality, and outcomes. This study examines the correlation between diabetes ratio as a primary diagnosis in home health agencies (HHAs) with the Home Health Care Consumer Assessment of Healthcare Providers and Systems (HHCAHPS) survey and the Outcome and Assessment Information Set (OASIS) star ratings. Our result indicates that HHAs with a higher proportion of patients with diabetes have lower ratings in health outcomes (bathing, breathing, moving from the bed, moving around, and controlling pain). The association was stronger in the case of diabetic cases with complications.

Diabetic retinopathy in type 1 diabetes patients in Western Norway

PURPOSE

To describe the prevalence of diabetic retinopathy (DR), associated risk factors and health-related quality of life (HRQoL) in a population-based cohort of patients with type 1 diabetes mellitus (DM1).

METHODS

All patients underwent a general and ophthalmic examination including seven-field stereo fundus photography for grading of DR and diabetic macular oedema (DMO). Kaplan-Meier survival analyses were performed to evaluate disease progression in relation to diabetes duration, age and year of diabetes onset. HRQoL and its association with DR were assessed by the Medical Outcomes Study Short Form 36 (SF-36) questionnaire.

RESULTS

A total of 237 DM1 patients were included. Mean age at inclusion was 34 years (range, 4-75 years), and mean diabetes duration was 19 years (range, 5 months-63 years). A total of 145 patients (61%) had DR. Sixty-two patients (26%) had mild, 39 (16%) moderate and 13 (5%) severe nonproliferative DR, while 31 (13%) had proliferative DR. The prevalence of DMO was 8%. The most important risk factors predicting severity of DR were diabetes duration (p < 0.0001) and HbA1c level (p < 0.0001). Neuropathy (p = 0.006), nephropathy (p = 0.004) and male gender (p = 0.02) were also significant predictors of DR. Compared to normative SF-36 data, there was a linear trend of decreasing HRQoL with increasing severity of DR that was statistically significant for the four physical dimension scores.

CONCLUSION

The prevalence of DR in DM1 was largely within the range of previous reports. Diabetes duration, HbA1c level, neuropathy, nephropathy and male gender were all significant predictors of DR severity. The patients with more severe DR had lower HRQoL.

The relationship between intensification of blood glucose-lowering therapies, health status and quality of life in type 2 diabetes: The Fremantle Diabetes Study Phase II

AIMS

To determine whether therapeutic intensification in type 2 diabetes influences health status and quality of life (QoL).

METHODS

We studied 930 participants in the longitudinal observational Fremantle Diabetes Study Phase II (mean age 65.3 years, 53.8% males, median diabetes duration 8.0 years) with valid data from baseline assessment and two biennial reviews (4 years of follow-up) between 2008 and 2015. The main outcome measures were the Short Form-12 version 2 physical and mental health composite scores (PCS, MCS) and the average weighted impact (AWI) score from the Audit of Diabetes Dependent QoL.

RESULTS

There were reductions in PCS at Year 4 compared with baseline and Year 2 in patients on stable diet-based management (n = 160), oral glucose-lowering medication (OGLM; n = 387), and insulin with/without OGLM (n = 168; P < 0.05), but no statistically significant temporal changes in MCS/AWI. Insulin-treated patients had the lowest PCS, MCS and AWI compared to the other two subgroups at each time-point (P ≤ 0.012). In participants initiating OGLM (n = 84) or insulin (n = 85), there were no differences in PCS, MCS or AWI at the biennial assessments either side of these therapeutic changes (P ≥ 0.08).

CONCLUSIONS

These real-life data show that treatment intensification, including insulin initiation, does not impact adversely on patient well-being in community-based type 2 diabetes. Since insulin use at entry was associated with longer diabetes duration, worse glycaemic control, and a greater risk of chronic complications, the burden of disease rather than treatment modality appears the primary determinant of health status and QoL.

Evaluation of the internal and external responsiveness of Short Form-12 Health Survey version 2 (SF-12v2) in patients with type 2 diabetes mellitus

PURPOSE

The evidence on the responsiveness of the Short Form-12 Health Survey version 2 (SF-12v2) in patients with type 2 diabetes mellitus (T2DM) is limited. The aim of this study was to examine both the internal and external responsiveness of the SF-12 measures in Chinese patients with T2DM.

METHODS

A prospective longitudinal observational study was conducted on 1443 T2DM patients managed in public primary care clinics between 2012 and 2013. These patients were surveyed at baseline and at 12 months using SF-12v2. The internal responsiveness was evaluated by linear mixed effect models. Meanwhile, the external responsiveness was tested by multiple linear regression models and receiver operating characteristic (ROC) curve analysis.

RESULTS

The internal responsiveness of the SF-12v2 to detect negative change was satisfactory among T2DM patients in worsened group, but only the general health domain of SF-12v2 could detect positive change among T2DM patients with improved group. For external responsiveness, the SF-12v2 detected a significant difference-in-difference between patients with worsened and stable/improved group, but not between patients with stable and improved group. The areas under the ROC curve for all domains and summary scales of the SF-12v2 were not statistically different from 0.7.

CONCLUSION

This study showed that the responsiveness of SF-12v2 might not achieve the standard. Despite the wide use of the SF-12v2, we would like to urge that both clinicians and researchers should use it with caution in longitudinal study.

Measuring the reliability and validity of the Greek edition of the Diabetes Quality of Life Brief Clinical Inventory

BACKGROUND

The present study focuses on studying the validity and reliability of the Greek edition of DQOL-BCI. DQOL-BCI includes 15 questions-elements that are evaluated on a 5-grade scale like Likert and two general form-shapes.

METHODS

The translation process was conducted in conformity with the guidelines of EuroQol group. A non-random sample of 65 people-patients diagnosed with diabetes I and II was selected. The questionnaire that was used to collect the data was the translated version of DQOL-BCI, and included the demographic characteristics of the interviewees. The content validity of DQOL-BCI was re-examined from a team of five experts (expert panel) for qualitative and quantitative performance. The completion of the questionnaire was done via a personal interview.

RESULTS

The sample consisted of 58 people (35 men and 23 women, 59.9 ± 10.9 years). The translation of the questionnaire was found appropriate in accordance to the peculiarities of the Greek language and culture. The largest deviation of values is observed in QOL1 (1.71) in comparison to QOL6 (2.98). The difference between the standard deviations is close to 0.6. The statistics results of the tests showed satisfactory content validity and high construct validity, while the high values for Cronbach alpha index (0.95) reveal high reliability and internal consistency.

CONCLUSIONS

The Greek version of DQOL-BCI has acceptable psychometric properties and appears to demonstrate high internal reliability and satisfactory construct validity, which allows its use as an important tool in evaluating the quality of life of diabetic patients in relation to their health.

The relationship between psychiatric morbidity and quality of life: interview study of Norwegian tsunami survivors 2 and 6 years post-disaster

BACKGROUND

The study investigated the impact of psychiatric disorders on Quality of Life (QOL) cross-sectionally and longitudinally in a group of Norwegian tourists severely exposed to the 2004 tsunami.

METHODS

Sixty-two adult Norwegian tsunami survivors were interviewed face to face 2 years post-tsunami (T1) and 58 were interviewed again by telephone 6 years post-tsunami (T2). The majority (81 %) reported direct exposure to the waves, and 14 participants (23 %) lost a close family member in the tsunami. Psychiatric morbidity was measured by structured clinical interviews and QOL was assessed with WHO's Quality of Life-Bref scale. Multiple linear regression analyses were performed to assess the independent effects of psychiatric disorders on QOL 2 and 6 years after the tsunami.

RESULTS

Psychiatric disorders, especially depression, but also PTSD and other anxiety disorders, were associated with reduced QOL. Psychiatric disorders were more strongly related to QOL at 6 years after the tsunami than at 2 years.

CONCLUSIONS

Psychiatric disorders, and especially depression, is related to reduced QOL in a disaster exposed population. Post-disaster psychiatric disorders, such as PTSD and especially depression, should be addressed properly in the aftermath of disasters.

The Aging, Community and Health Research Unit-Community Partnership Program for older adults with type 2 diabetes and multiple chronic conditions: a feasibility study

BACKGROUND

Few studies have examined the effectiveness of community-based self-management interventions in older adults with type 2 diabetes mellitus (T2DM) and multiple chronic conditions (MCC). The objectives of this study were to examine the feasibility of implementation in practice (primary) and the feasibility of study methods and potential effectiveness (secondary) of the Aging, Community and Health-Community Partnership Program, a new 6-month interprofessional, nurse-led program to promote diabetes self-management in older adults (>65 years) with T2DM and MCC.

METHODS

This study used a prospective one-group pre-test/post-test design. Participants were recruited from a specialized diabetes clinic. They received a median of three in-home/clinic visits by certified diabetes educators (CDEs) and attended a median of three group wellness sessions provided by the CDEs in partnership with a community-based seniors' association. The primary outcome was the feasibility of the program (acceptability, fidelity, implementation barriers/facilitators). Secondary outcomes included the feasibility of the study methods (recruitment/retention rates and procedures, eligibility criteria, data collection and analysis methods) and potential effectiveness of the program based on 6-month changes in self-reported outcomes including self-management behavior (diet, exercise, self-monitoring), health status (quality of life, mental health), and costs of service use. Analysis of feasibility outcomes was primarily based on descriptive statistics. The potential effectiveness of the program was explored using different tests, with the results expressed using descriptive statistics and effect estimates (95 % confidence intervals).

RESULTS

In total, 45 (88 %) of 51 eligible persons consented to participate. Of these, 37 (82 %) completed the 6-month follow-up. Participants and providers viewed the program as acceptable and feasible. Participants had a higher SF-12 physical component summary score at 6 months compared with baseline (mean score difference 3.0, 95 % CI 0.2-5.8). Median costs for diabetes care increased over 6 months (reflecting inclusion of program costs), while other service costs either decreased or remained unchanged.

CONCLUSIONS

This study offers preliminary evidence that the program was feasible to deliver and acceptable to participants and providers. Initial results suggest that the program may improve physical functioning. A randomized controlled trial is feasible, with some adaptations to the program and study methods that were identified from this feasibility study.

Stages of change for physical activity and dietary habits in persons with type 2 diabetes included in a mobile health intervention: the Norwegian study in RENEWING HEALTH

OBJECTIVE

The aim of this study was to investigate stages of change for physical activity and dietary habits using baseline data from persons with type 2 diabetes included in a mobile health intervention. We examined the associations between stages of change for physical activity change and dietary change, and between stages of change for each behavior and individual characteristics, health-related quality of life, self-management, depressive symptoms, and lifestyle.

RESEARCH DESIGN AND METHODS

We examined 151 persons with type 2 diabetes with an glycated hemoglobin (HbA1c) level ≥7.1%, aged ≥18 years at baseline of a randomized controlled trial, before testing a mobile app with or without health counseling. Stages of change were dichotomized into 'pre-action' and 'action'. Self-management was measured using the Health Education Impact Questionnaire (heiQ) where a higher score reflects increased self-management, and health-related quality of life was measured with the Short-Form-36 (SF-36). Logistic regression modeling was performed.

RESULTS

The median HbA1c level was 7.9% (7.1-12.4), 90% were overweight or obese, and 20% had ≥3 comorbidities. 58% were in the preaction stage for physical activity change and 79% in the preaction stage for dietary change. Higher scores of self-management were associated with an increased chance of being in the action stage for both dietary change and physical activity change. Higher body mass index was associated with an 8% reduced chance of being in the action stage for physical activity change (OR 0.92, 95% CI 0.86 to 0.99).

CONCLUSIONS

Being in the action stage was associated with higher scores of self-management, crucial for type 2 diabetes. Over half of the participants were in the preaction stage for physical activity and dietary change, and many had a high disease burden with comorbidities and overweight.

Change in cardio-protective medication and health-related quality of life after diagnosis of screen-detected diabetes: Results from the ADDITION-Cambridge cohort

AIMS

Establishing a balance between the benefits and harms of treatment is important among individuals with screen-detected diabetes, for whom the burden of treatment might be higher than the burden of the disease. We described the association between cardio-protective medication and health-related quality of life (HRQoL) among individuals with screen-detected diabetes.

METHODS

867 participants with screen-detected diabetes underwent clinical measurements at diagnosis, one and five years. General HRQoL (EQ5D) was measured at baseline, one- and five-years, and diabetes-specific HRQoL (ADDQoL-AWI) and health status (SF-36) at one and five years. Multivariable linear regression was used to quantify the association between change in HRQoL and change in cardio-protective medication.

RESULTS

The median (IQR) number of prescribed cardio-protective agents was 2 (1 to 3) at diagnosis, 3 (2 to 4) at one year and 4 (3 to 5) at five years. Change in cardio-protective medication was not associated with change in HRQoL from diagnosis to one year. From one year to five years, change in cardio-protective agents was not associated with change in the SF-36 mental health score. One additional agent was associated with an increase in the SF-36 physical health score (2.1; 95%CI 0.4, 3.8) and an increase in the EQ-5D (0.05; 95%CI 0.02, 0.08). Conversely, one additional agent was associated with a decrease in the ADDQoL-AWI (-0.32; 95%CI -0.51, -0.13), compared to no change.

CONCLUSIONS

We found little evidence that increases in the number of cardio-protective medications impacted negatively on HRQoL among individuals with screen-detected diabetes over five years.

Weight loss is not mandatory for exercise-induced effects on health indices in females with metabolic syndrome

The aim of this study was to investigate the impact of moderate aerobic training on functional, anthropometric, biochemical, and health-related quality of life (HRQOL) parameters on women with metabolic syndrome (MS). Fifteen untrained women with MS performed moderate aerobic training for 15 weeks, without modifications of dietary behaviours. Functional, anthropometric, biochemical, control diet record and HRQOL parameters were assessed before and after the training. Despite body weight maintenance, the patients presented decreases in waist circumference (P = 0.001), number of MS components (P = 0.014), total cholesterol (P = 0.049), HDL cholesterol (P = 0.004), LDL cholesterol (P = 0.027), myeloperoxidase activity (P = 0.002) and thiobarbituric acid-reactive substances levels (P = 0.006). There were no differences in total energy, carbohydrate, protein and lipid intake pre- and post-training. Furthermore, improvements in the HRQOL subscales of physical functioning (P = 0.03), role-physical (P = 0.039), bodily pain (P = 0.048), general health (P = 0.046) and social functioning scoring (P = 0.011) were reported. Despite the absence of weight loss, aerobic training induced beneficial effects on functional, anthropometric, biochemical and HRQOL parameters in women with MS.

Health-related quality of life in women and men with type 2 diabetes: a comparison across treatment groups

AIM

This study compares health-related quality of life (HRQL) in patients with type 2 diabetes (T2DM) across treatment groups and explores gender differences.

METHODS

Four regional surveys (KORA, CARLA, SHIP, DHS) and a national survey (GNHIES98) were pooled at individual level. HRQL was assessed with the SF-12/-36v1. Linear regression models were used to assess the effect of T2DM by treatment type (no medication; oral; oral/insulin combination; insulin) on the physical (PCS-12) and mental summary score (MCS-12) and the SF-6D, controlling for age, sex, study and covariates. We also performed an explanatory analysis of single items.

RESULTS

PCS-12 scores and treatment type were associated (P-value 0.006), with lowest values for insulin treatment (-4.44 vs. oral; -4.41 vs. combination). MCS-12 scores were associated with treatment type and gender (P-value <0.012), with lower scores for women undergoing oral (-4.25 vs. men) and combination treatment (-6.99 vs. men). Similar results were observed for SF-6D utilities and single items, related to mental health, social functioning, vitality and role limitation (emotional). Comorbidities were predictors of lower PCS-12 and SF-6D scores.

CONCLUSIONS

T2DM treatment impacts differently on physical and mental HRQL and on women and men. Further studies of gender-specific perceptions of T2DM treatment regimens are needed.

Improvements in quality of life associated with biphasic insulin aspart 30 in type 2 diabetes patients in China: results from the A1chieve® observational study

BACKGROUND

Based on the 24-week, prospective, non-interventional, observational study, A1chieve®, we investigated how health-related quality of life (HRQoL) changed, and the predictors of such changes, in Chinese people with type 2 diabetes mellitus (T2DM) after starting with, or switching to, biphasic insulin aspart 30 (BIAsp 30).

METHODS

In total, 8,578 people with T2DM starting treatment with, or switching to, BIAsp 30 were recruited from 130 urban hospitals in China. HRQoL was assessed at baseline and 24 weeks using the EuroQol-5 dimensions (EQ-5D) questionnaire. Descriptive statistics, paired t-test, and chi-square test were conducted and the linear ordinary least squares regression model was used to determine predictors for changes in EQ-5D score.

RESULTS

Haemoglobin A1c (HbA1c) decreased from 9.5% to 7.0% after 24 weeks. The reported HRQoL measured by the EQ-5D visual analogue scale score increased by 6.2 (p < 0.001) from 75.8 to 82.0, and EQ-5D index score increased by 0.018 (p < 0.001) from 0.875 to 0.893 for the cohort over 24 weeks. The percentage of patients reporting no problems in the mobility, pain/discomfort, and anxiety/depression dimensions of EQ-5D increased significantly (p < 0.001) from 88.4% to 91.4%, 77.3% to 82.8%, and 74.2% to 77.1%, respectively. Patients with higher HbA1c levels at baseline, major hypoglycaemia or micro-complications exhibited significantly larger changes in EQ-5D scores than those with lower baseline HbA1c levels, without major hypoglycaemia or micro-complications after controlling for demographics and other baseline characteristics.

CONCLUSIONS

BIAsp 30 treatment was associated with improved glycaemic control and HRQoL in T2DM patients in China. Patients with worse health conditions were more likely to experience larger improvements in HRQoL than those with better health conditions.

Application of a health-related quality of life conceptual model in community-dwelling older Chinese people with diabetes to understand the relationships among clinical and psychological outcomes

AIMS/INTRODUCTION

The present study applied the Wilson-Cleary model of health-related quality of life (HRQOL) by using the structural equation modeling (SEM) approach to understand the interrelationships among clinical, sociodemographic and psychological characteristics in older people with diabetes.

MATERIALS AND METHODS

This was a cross-sectional study with 452 Chinese older people with diabetes recruited from three primary care clinics. A series of assessments were made, including four instruments: the Chinese version of the Short Form 36 Health Survey, Older American Resources and Services Multidimensional Functional Assessment Questionnaire, Rand Mental Health Inventory and Medical Outcomes Study Social Support Survey; and clinical outcomes (diabetes-related characteristics and physiological data).

RESULTS

In the present study, we identified six patient individual and environmental characteristics, namely, age, sex, physical activity, psychological distress, social support and adequacy of income, that significantly influence HRQOL directly or by way of physical functional status and general health perception.

CONCLUSIONS

Improving social and financial support as well as providing interventions to promote physical activity and to cope with psychological distress in this patient population might be effective to eventually enhance their HRQOL. The present findings add to the literature the underlying complex biological and psychological processes of HRQOL, and take the body of knowledge in HRQOL of older people with diabetes to a theoretical level, and provide insights for development of appropriate strategies to optimize their HRQOL.

Interventions to improve safe and effective medicines use by consumers: an overview of systematic reviews

BACKGROUND

Many systematic reviews exist on interventions to improve safe and effective medicines use by consumers, but research is distributed across diseases, populations and settings. The scope and focus of such reviews also vary widely, creating challenges for decision-makers seeking to inform decisions by using the evidence on consumers' medicines use.This is an update of a 2011 overview of systematic reviews, which synthesises the evidence, irrespective of disease, medicine type, population or setting, on the effectiveness of interventions to improve consumers' medicines use.

OBJECTIVES

To assess the effects of interventions which target healthcare consumers to promote safe and effective medicines use, by synthesising review-level evidence.

METHODS

SEARCH METHODS

We included systematic reviews published on the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects. We identified relevant reviews by handsearching databases from their start dates to March 2012.

SELECTION CRITERIA

We screened and ranked reviews based on relevance to consumers' medicines use, using criteria developed for this overview.

DATA COLLECTION AND ANALYSIS

We used standardised forms to extract data, and assessed reviews for methodological quality using the AMSTAR tool. We used standardised language to summarise results within and across reviews; and gave bottom-line statements about intervention effectiveness. Two review authors screened and selected reviews, and extracted and analysed data. We used a taxonomy of interventions to categorise reviews and guide syntheses.

MAIN RESULTS

We included 75 systematic reviews of varied methodological quality. Reviews assessed interventions with diverse aims including support for behaviour change, risk minimisation and skills acquisition. No reviews aimed to promote systems-level consumer participation in medicines-related activities. Medicines adherence was the most frequently-reported outcome, but others such as knowledge, clinical and service-use outcomes were also reported. Adverse events were less commonly identified, while those associated with the interventions themselves, or costs, were rarely reported.Looking across reviews, for most outcomes, medicines self-monitoring and self-management programmes appear generally effective to improve medicines use, adherence, adverse events and clinical outcomes; and to reduce mortality in people self-managing antithrombotic therapy. However, some participants were unable to complete these interventions, suggesting they may not be suitable for everyone.Other promising interventions to improve adherence and other key medicines-use outcomes, which require further investigation to be more certain of their effects, include:· simplified dosing regimens: with positive effects on adherence;· interventions involving pharmacists in medicines management, such as medicines reviews (with positive effects on adherence and use, medicines problems and clinical outcomes) and pharmaceutical care services (consultation between pharmacist and patient to resolve medicines problems, develop a care plan and provide follow-up; with positive effects on adherence and knowledge).Several other strategies showed some positive effects, particularly relating to adherence, and other outcomes, but their effects were less consistent overall and so need further study. These included:· delayed antibiotic prescriptions: effective to decrease antibiotic use but with mixed effects on clinical outcomes, adverse effects and satisfaction;· practical strategies like reminders, cues and/or organisers, reminder packaging and material incentives: with positive, although somewhat mixed effects on adherence;· education delivered with self-management skills training, counselling, support, training or enhanced follow-up; information and counselling delivered together; or education/information as part of pharmacist-delivered packages of care: with positive effects on adherence, medicines use, clinical outcomes and knowledge, but with mixed effects in some studies;· financial incentives: with positive, but mixed, effects on adherence.Several strategies also showed promise in promoting immunisation uptake, but require further study to be more certain of their effects. These included organisational interventions; reminders and recall; financial incentives; home visits; free vaccination; lay health worker interventions; and facilitators working with physicians to promote immunisation uptake. Education and/or information strategies also showed some positive but even less consistent effects on immunisation uptake, and need further assessment of effectiveness and investigation of heterogeneity.There are many different potential pathways through which consumers' use of medicines could be targeted to improve outcomes, and simple interventions may be as effective as complex strategies. However, no single intervention assessed was effective to improve all medicines-use outcomes across all diseases, medicines, populations or settings.Even where interventions showed promise, the assembled evidence often only provided part of the picture: for example, simplified dosing regimens seem effective for improving adherence, but there is not yet sufficient information to identify an optimal regimen.In some instances interventions appear ineffective: for example, the evidence suggests that directly observed therapy may be generally ineffective for improving treatment completion, adherence or clinical outcomes.In other cases, interventions may have variable effects across outcomes. As an example, strategies providing information or education as single interventions appear ineffective to improve medicines adherence or clinical outcomes, but may be effective to improve knowledge; an important outcome for promoting consumers' informed medicines choices.Despite a doubling in the number of reviews included in this updated overview, uncertainty still exists about the effectiveness of many interventions, and the evidence on what works remains sparse for several populations, including children and young people, carers, and people with multimorbidity.

AUTHORS' CONCLUSIONS

This overview presents evidence from 75 reviews that have synthesised trials and other studies evaluating the effects of interventions to improve consumers' medicines use.Systematically assembling the evidence across reviews allows identification of effective or promising interventions to improve consumers' medicines use, as well as those for which the evidence indicates ineffectiveness or uncertainty.Decision makers faced with implementing interventions to improve consumers' medicines use can use this overview to inform decisions about which interventions may be most promising to improve particular outcomes. The intervention taxonomy may also assist people to consider the strategies available in relation to specific purposes, for example, gaining skills or being involved in decision making. Researchers and funders can use this overview to identify where more research is needed and assess its priority. The limitations of the available literature due to the lack of evidence for important outcomes and important populations, such as people with multimorbidity, should also be considered in practice and policy decisions.

Does a 2.5-year self-management education and support intervention change patterns of healthcare use in African-American adults with type 2 diabetes?

AIMS

To investigate the impact of a 2.5-year diabetes self-management education and support intervention on healthcare use and to examine factors associated with patterns of healthcare use.

METHODS

We recruited 60 African-American adults with type 2 diabetes who completed a 2.5-year empowerment-based diabetes self-management education and support intervention. Primary healthcare use outcomes included acute care visits, non-acute care visits and days lost to disability. Acute care was a composite score calculated from the frequency of urgent care visits, emergency department visits and hospitalizations. Non-acute care measured the frequency of scheduled outpatient visits. To examine change in patterns of healthcare use, we compared the frequency of healthcare visits over the 6-month period preceding the intervention with that in the last 6 months of the intervention.

RESULTS

No significant changes in patterns of healthcare use were found for acute care, non-acute care or days lost to disability. Multiple regression models found higher levels of depression (P = 0.001) to be associated with a greater number of non-acute healthcare visits, and found longer duration of diabetes (P = 0.019) and lower levels of diastolic blood pressure (P = 0.025) to be associated with fewer days lost to disability.

CONCLUSIONS

Participation in a long-term diabetes self-management education and support intervention had no impact on healthcare use in our sample of African-American subjects.

Diabetes in Europe: an update

Diabetes is among the leading causes of death in the IDF Europe Region (EUR), continues to increase in prevalence with diabetic macro- and microvascular complications resulting in increased disability and enormous healthcare costs. In 2013, the number of people with diabetes is estimated to be 56 million in EUR with an overall estimated prevalence of 8.5%. However, estimates of diabetes prevalence in 2013 vary widely in the 56 diverse countries in EUR from 2.4% in Moldova to 14.9% in Turkey. Trends in diabetes prevalence also vary between countries with stable prevalence since 2002 for many countries but a doubling of diabetes prevalence in Turkey. For 2035, a further increase of nearly 10 million people with diabetes is projected for the EUR. Prevalence of type 1 has also increased over the past 20 years in EUR and there was estimated to be 129,350 cases in children aged 0-14 years in 2013. Registries provide valid information on incidence of type 1 diabetes with more complete data available for children than for adults. There are large differences in distribution of risk factors for diabetes at the population level in EUR. Modifiable risk factors such as obesity, physical inactivity, smoking behaviour (including secondhand smoking), environmental pollutants, psychosocial factors and socioeconomic deprivation could be tackled to reduce the incidence of type 2 diabetes in Europe. In addition, diabetes management is a major challenge to health services in the European countries. Improved networking practices of health professionals and other stakeholders in combination with empowerment of people with diabetes and continuous quality monitoring need to be further developed in Europe.

Benchmarks for interpretation of score differences on the SF-36 health survey for patients with diabetes

OBJECTIVE

To estimate clinical and social benchmarks for interpretation of score differences on the Short-Form 36 Health Survey, and apply these benchmarks to populations with diabetes mellitus (DM).

METHODS

Using survival and logistic regression models, we reanalyzed data from three US cohorts: the Medical Outcomes Study (N = 3,445; 541 patients with DM), the Medicare Health Outcomes Survey (N = 78,183; 16,388 patients with DM), and the QualityMetric 2009 Norming Study (N = 4,040; 580 patients with DM). Outcome variables were mortality, hospitalization, current inability to work, and loss of ability to work.

RESULTS

Benchmarks were robust across disease groups, but varied according to age and score level. A 1-point lower score on the Physical Function, General Health, and Physical Component Summary scales was associated with a 1.05 to 1.09 relative risk (RR) of mortality for the typical patient with DM, with stronger associations in the younger age groups. For several scales (Physical Function, Role Physical, Bodily Pain, General Health, Vitality, Social Function, and Role Emotional), the associations with mortality also depended on score level, with stronger associations in the lower score ranges (i.e., patients in worse health). A 1-point lower score on the Physical Function, Role Physical, Bodily Pain, General Health, Vitality, Social Function, and Physical Component Summary scales implied a 1.02 to 1.04 RR of hospitalization, a 1.07 to 1.12 RR of being unable to work, and a 1.04 to 1.07 RR of losing the ability to work.

CONCLUSIONS

A 1-point lower score on selected Short-Form 36 Health Survey scales is associated with an excess risk of up to 9% for mortality and 12% for inability to work.

Resource utilisation and quality of life following initiation of insulin detemir in patients with type 2 diabetes mellitus

OBJECTIVE

Barriers to insulin initiation in type 2 diabetes mellitus (T2DM) include fear of treatment complexity and perceived lack of time and resources by primary care physicians. The SOLVE study investigated the effect of insulin initiation on resource utilisation and patient quality of life.

METHODS

SOLVE was a 24-week cohort study in 10 countries evaluating the safety and effectiveness of initiating once-daily insulin detemir in patients with T2DM. Patient quality of life was assessed using the Insulin Treatment Appraisal Scale (ITAS).

RESULTS

A total of 14,611 (84%) patients completed the 24-week study. During the study, HbA1c improved by 1.3 ± 1.5%. The corresponding insulin dose increased from 13 ± 6 IU (0.16 ± 0.09 IU/kg) at baseline, to 22 ± 16 IU (0.27 ± 0.17 IU/kg) at final visit. FlexPen was the preferred device (63%) for insulin administration. The time taken to teach patients to self-inject and perform dose self-adjustment was 15 ± 13 min and 11 ± 11 min, respectively. The quality of life analysis included 6875 patients. The addition of insulin was associated with an improvement in mean ITAS score [-3.5 (95% CI -3.8, -3.3), p < 0.001]. Physicians reported the use or self-adjustment of insulin detemir as easy or very easy in 79% of participants; and satisfaction with the level of glycaemic control was reported for 74% of patients.

CONCLUSIONS

Initiating basal insulin therapy resulted in a substantial decrease in HbA1c and improved patients' perceptions of insulin treatment.

Effects of insulin changes on quality of life and glycemic control in Japanese patients with type 2 diabetes mellitus: The insulin-changing study intending to gain patients' insights into insulin treatment with patient-reported health outcomes in actual clinical treatments (INSIGHTs) study

Aims/Introduction

Our primary objective was to assess changes in quality of life (QOL) associated with changes in insulin regimen in patients with type 2 diabetes mellitus. Secondary objectives were to assess the reasons for and patterns of changes in insulin regimen, and the effects on glycemic control.

Materials and Methods

This 12‐week, observational study included patients with type 2 diabetes mellitus (n = 625) who planned to change insulin regimen (type of insulin, injection device and/or number of injections). The primary outcome measure was a change from baseline in QOL assessed by the Insulin Therapy‐Related (ITR) QOL questionnaire. The secondary outcome measures included change from baseline in plasma glycated hemoglobin (HbA_1c) level, the reasons for and pattern of insulin regimen change, and change from baseline in QOL assessed by Diabetes Treatment Satisfaction Questionnaire (DTSQ).

Results

QOL did not worsen during the study. Improvements were seen in the ITR‐QOL ‘daily activities’ subscale score (baseline: 12.7 ± 2.3; week 12: 12.9 ± 2.3; P = 0.038, n = 568) and the DTSQ ‘perceived frequency of hyperglycemia’ subscale score (baseline: 3.4 ± 1.6; week 12: 3.0 ± 1.7; P < 0.001, n = 573). Glycemic control improved, as evidenced by decreased plasma HbA_1c levels (baseline: 8.21 ± 1.47%; week 12: 7.85 ± 1.31%; P < 0.001, n = 606).

Conclusions

It was suggested that insulin regimen changes might improve glycemic control in Japanese patients with type 2 diabetes mellitus without worsening QOL. This trial was registered with ClinicalTrials.gov (no. NCT01055808).

A changed pattern of insulin use following the introduction of basal analog insulin treatment in primary care

AIMS

We analyzed the impact of the removal of administrative restrictions on basal analog insulin prescribing by primary care physicians in the year 2008 in a large HMO.

METHODS

This cross-sectional database study of patients with diabetes study was conducted in Maccabi Healthcare Services, the second largest HMO in Israel, insuring 1.9 million members countrywide. The research population included men over 40 and women over the age of 45 from MHS diabetes registry during the time period 1.1.2002-31.12.2009.

RESULTS

After removal of basal analog insulin prescription restrictions, more primary care physicians initiated treatment with basal analog insulin than with other types of insulin and did so with fewer referrals for specialty diabetes consultation. No growth in the relative number of patients commencing insulin use was observed, nor did we find an earlier initiation of insulin.

CONCLUSION

In the first year following the relaxation of prescribing restrictions on the use of basal analog insulin we observed an increase in its use amongst patients previously treated with other types of insulin. The administrative changes did not result in an overall increase in the use of insulin in the study population.

A psychological support program for individuals with Type 1 diabetes

We aimed to test the effects of a psychological support program on the psychological distress, mood, and quality of life of well-educated individuals with type 1 diabetes. A newly developed support program was offered to 60 patients with type 1 diabetes on intensive insulin treatment, previously enrolled in group-care educational programs. Thirty-three subjects participated (experimental group, in groups of 8-12 subjects); 22, who postponed their entry, were used as controls. The program consisted of 7 weekly work sessions of 2 hours chaired by a psychologist and covered aspects of daily living with diabetes using role-playing, metaplan, and problem solving. At baseline and approximately 6 months later, all participants completed a battery of questionnaires, and the differences between the experimental and the control group were analyzed by repeated-measurements ANOVA. In response to the psychological support program, subjects in the experimental group reduced their depressive mood (Beck Depression Inventory and depression scales of the Psychological Well-Being Index) and anxiety (Self-rating Anxiety Scale), improved disease-specific quality of life (Symptom and Well-Being scales of the Well-Being Enquiry for Diabetes), increased their internal and decreased their external locus of control. These changes were accompanied by a 0.3% decrease in glycosylated hemoglobin, whereas no significant changes were observed in the control group (ANOVA, P = 0.032). These results underline the importance of psychological aspects in individuals with type 1 diabetes; treating the psychological aspects related to the disease may be as important as medical control in order to improve living with diabetes.

Psychological status and diabetes-related distress of Chinese type 1 diabetes patients in Jiangsu province, China

We sought to assess the psychological status and diabetes-related distress of Chinese type 1 diabetes patients in Jiangsu province, China. According to the World Health Organization criteria, 42 patients with type 1 diabetes were enrolled in the study and assessed with the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and Diabetes Distress Scale (DDS). All data were tabulated and statistical analyses were performed. The study summarized cases of 42 patients with type 1 diabetes, including 17 males and 25 females with a mean age of 23±12 years and a mean duration of diabetes of 7±6 years. Compared to the Chinese normative data, the SAS standard score was significantly higher, whereas SDS standard score had no statistical significance. The SAS standard score was most highly correlated with diabetes duration (γ = 0.547, P = 0.011). Additionally, 19.5% of the patients had moderate or even severe diabetes-related distress and 21.4% had moderate or even severe emotional burden while 26.2% had regimen-related distress. Multiple stepwise regression analysis showed that the mean correlation between DDS and the four domains was high, particularly the emotional burden domain (estimated β = 0.363, P < 0.001) and regimen-related distress domain (estimated β = 0.356, P < 0.001). The correlation between SAS and DDS was positive (estimated β = 0.039, P = 0.027). In conclusion, the results showed the importance of psychological aspects in Chinese individuals with type 1 diabetes. Screening and treatment of psychological aspects may result in better adherence and increased quality of life for patients with diabetes.

Aging, diabetes, and the public health system in the United States

Diabetes (diagnosed or undiagnosed) affects 10.9 million US adults aged 65 years and older. Almost 8 in 10 have some form of dysglycemia, according to tests for fasting glucose or hemoglobin A1c. Among this age group, diagnosed diabetes is projected to reach 26.7 million by 2050, or 55% of all diabetes cases. In 2007, older adults accounted for $64.8 billion (56%) of direct diabetes medical costs, $41.1 billion for institutional care alone. Complications, comorbid conditions, and geriatric syndromes affect diabetes care, and medical guidelines for treating older adults with diabetes are limited. Broad public health programs help, but effective, targeted interventions and expanded surveillance and research and better policies are needed to address the rapidly growing diabetes burden among older adults.

Effect of short-term intensive insulin therapy on quality of life in type 2 diabetes

RATIONALE, AIMS AND OBJECTIVES

Short-term intensive insulin therapy (IIT) early in the course of type 2 diabetes can improve pancreatic beta-cell function and even induce normoglycemia that persists post-therapy. In spite of this benefit, insulin is often delayed until late in the course of disease partly because of its perceived negative impact on quality of life (QOL). Therefore, we sought to examine the effect of early implementation of short-term IIT on patient-reported QOL and treatment satisfaction.

METHODS

A total of 34 patients with type 2 diabetes (5.9 ± 6.6 years duration, on zero to two oral antihyperglycaemic agents) underwent 4-8 weeks of IIT consisting of basal detemir and pre-meal insulin aspart. Patient-reported QOL, treatment satisfaction and symptom distress were assessed at baseline and post-IIT using the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), Diabetes Quality of Life Measure (DQOL), and Diabetes Symptoms Checklist-Revised (DSC-R).

RESULTS

There was a significant improvement in glycated haemoglobin post-IIT (mean 6.5% vs. 7%; P < 0.001). All 34 patients tolerated IIT well with no severe hypoglycaemia. Following IIT, the SF-36 showed a significant improvement compared to baseline in reported physical functioning (mean 88.2 vs. 83.3, P = 0.009), general health (69.4 vs. 65.6, P = 0.03), and general mental health (85.2 vs. 82.2, P = 0.04). The DQOL demonstrated a significant improvement in global health perception (P = 0.02), diabetes worry (P = 0.006) and treatment satisfaction (P = 0.007). The DSC-R revealed a significant improvement in the diabetes-related total symptom score (P = 0.01).

CONCLUSIONS

Contrary to popular perception, a short course of IIT resulted in significant improvements in QOL and treatment satisfaction, demonstrating the patient acceptability of early insulin therapy.

Quality of life in type 2 diabetes mellitus after a very low calorie diet and exercise

OBJECTIVE

To evaluate whether the addition of exercise to a very low calorie diet (VLCD) has beneficial short- and long-term effects on health-related quality of life (QoL) in obese patients with type 2 diabetes mellitus (T2DM).

METHODS

We included 27 obese, insulin-dependent T2DM patients in a 16-week VLCD study, of whom 13 participated simultaneously in an exercise program (VLCD+E). Before, immediately after and 18 months after the intervention anthropometric measurements, glucoregulation and QoL (SF-36, HADS, NHP and MFI-20) were assessed. Patients were compared to healthy lean and obese (matched for body mass index) controls matched for gender and age.

RESULTS

At baseline, T2DM patients had significantly worse QoL scores in 18 and 14 of the 22 subscales of the QoL questionnaires, compared to lean and obese controls, resp. The 16-week VLCD (n=27) decreased bodyweight (-25.4±1.3 kg, p<0.0001, p=0.179 between groups), and improved glucoregulation (HbA1c -1.3±0.3%, p<0.0001, p=0.488 between groups) and 9 (VLCD-only) and 11 (VLCD+E) of the 22 subscales of QoL. After 18 months, in the VLCD+E group the QoL subscales did not differ from those in obese controls and only 4 of the 22 subscales were significantly worse compared to lean controls. However, in the VLCD-only group 17 and 13 of the 22 QoL subscales were significantly worse compared to the lean and obese controls, resp.

CONCLUSION

A 16-week VLCD induces considerable weight loss, metabolic amelioration, and major improvements in QoL in obese T2DM patients. The addition of exercise is of paramount importance for the maintenance of better QoL.

Seligman's Theory of Attributional Style: Optimism, Pessimism, and Quality of Life after Heart Transplant

Context—

Posttransplant quality of life can be significantly affected by personality characteristics identified before transplant.

Objective—

Although overall quality of life in heart transplant patients improves after transplant, many studies reveal poorer mental health outcomes after transplant. We aimed to determine whether transplant recipients with an optimistic explanatory style had improved quality of life, fewer depressive symptoms, and increased survival.

Design—

We reviewed 68 patients who had completed a Minnesota Multiphasic Personality Inventory a mean of 2 years before transplant and examined associations between scores on the Optimism-Pessimism scale, survival rates, and results from the Health Status Questionnaire nearly 4 years after transplant.

Results—

Optimism was significantly associated with higher quality of life even after age (at the time of transplant), sex, depression score before transplant, time from the personality inventory to transplant, and time from transplant to the Health Status Questionnaire were controlled for. Furthermore, a pessimistic explanatory style was significantly associated with self-reported depressive symptoms, even after depression before transplant was adjusted for. Neither optimism nor pessimism was associated with length of survival.

Conclusions—

Pretransplant patients with a pessimistic explanatory style reported depressive symptoms nearly 5 years later. Furthermore, over the same time span, patients with an optimistic explanatory style described a significantly higher quality of life than the pessimists described.

Diabetes-specific Quality of Life After a Low-carbohydrate and Low-fat Dietary Intervention

Purpose

The purpose of the study was to examine the impact of a 12-month weight loss intervention with either a low-carbohydrate or a low-fat diet on quality of life (QOL) among obese patients with type 2 diabetes.

Methods

Participants were enrolled in a randomized trial comparing a low-carbohydrate to a low-fat diet in type 2 diabetes. QOL was assessed with the Diabetes-39 questionnaire, which measures QOL within 5 distinct scales: anxiety and worry, diabetes control, energy and mobility, social burden, and sexual functioning. Repeated measures ANOVA compared change in QOL scales at baseline and 6 and 12 months.

Results

Forty-six participants completed all measures. Following 12 months, there was a significant reduction in the scores related to sexual function and energy and mobility, suggesting improvement in QOL related to these domains. These changes were not significantly different between dietary arms. Changes in weight, A1C, and dietary composition were not significantly correlated with changes in QOL.

Conclusions

Participants with diabetes have various options for weight loss. Dietary interventions with either low-carbohydrate or low-fat diets may lead to some improvements in QOL in patients with type 2 diabetes.

Impact of physical activity and bodyweight on health-related quality of life in people with type 2 diabetes

PURPOSE

Increasing obesity prevalence rates in the general population are reflected in patients with type 2 diabetes. Health-related quality of life (HRQoL) is negatively affected in patients who are overweight or have diabetes, but physical activity (PA) is proven to have positive side effects on the perceived quality of life. Little is known about the relationship of PA with obesity, diabetes, and HRQoL. Therefore, the objective of the present study was to examine the relationship between HRQoL and PA in type 2 diabetics in association with the severity of overweight.

METHODS

This was a cross-sectional multicenter cohort study involving 370 outpatients with type 2 diabetes. Participants completed the SF-36 Health Survey (SF-36(®)) and the Freiburger Questionnaire for Physical Activity (FFkA). Endurance capacity was tested with a 2 km walking test. t-tests, analysis of variance, Pearson's correlation test, and multiple regression analyses were performed.

RESULTS

HRQoL is negatively affected by body mass index (BMI). The results show that patients with type 2 diabetes and grade II obesity (BMI > 35) have a lower HRQoL than overweight patients (BMI 25-29.99) and patients with grade I obesity (BMI 30-35). HRQoL decreases with decreasing PA in all dimensions of the SF-36. PA remains a significant predictor of physical composite summary (B = 0.09; β = 0.11; P < 0.05), physical function (B = 0.10; β = 0.13; P < 0.01), mental composite summary (B = 0.13; β = 0.20; P < 0.001), vitality (B = 0.15; β = 0.24; P < 0.001), and psychological well-being (B = 0.11; β = 0.18; P < 0.01) when controlling for age, sex, and BMI.

CONCLUSION

Because of the strong association between being overweight/obese and several risk factors for morbidity and mortality, reversing the obesity epidemic is an urgent priority. Based upon the results of this study and the available evidence of the efficacy of PA for preventing and treating those who are overweight or obese, health care professionals should continue to stress the importance of PA as a treatment option.
