Abstract
The Hawai'i Demonstration to Maintain Independence and Employment was a randomized controlled trial examining the effect of a participant-driven, multicomponent intervention on 190 employed adults with diabetes, 36% of whom were Asian and 35% of whom were Native Hawaiian or Pacific Islander. A no treatment concurrent control group was used, and the treatment group was provided an intervention that paired each participant with a life coach and a pharmacist counselor with whom they worked to achieve collaboratively chosen goals. Treatment fidelity data suggest that the intervention was largely implemented as planned. Life coaches and pharmacists performed key program functions with high to moderate adherence. The quality of their adherence to the intervention model ranged from basic to above basic and below basic to above basic for life coaches and pharmacists, respectively. Results of repeated-measures analysis of covariance analyses indicate that the intervention had a significant positive effect on participants' diabetes self-efficacy, quality of life, and body mass index but not on hemoglobin A1c levels. Further analyses examining just the treatment group indicate a dosage effect, with body mass index and quality of life outcomes optimized among participants who engaged in a greater number of sessions with life coaches and pharmacists. Implications of the study findings for practice are discussed.

Abstract
Incretin-based therapies have a glucose-dependent mode of action that results in excellent glucose-lowering efficacy with very low risk of hypoglycaemia, and weight neutrality [dipeptidyl peptidase-4 (DPP-4) inhibitors] or weight loss [glucagon-like peptide-1 (GLP-1) receptor agonists], in people with type 2 diabetes mellitus (T2DM). Patient-reported outcomes (PROs) complement physician evaluations of efficacy and tolerability and offer insights into the subjective experience of using modern diabetes treatments. We conducted a systematic search of clinical trials of the GLP-1 receptor agonists liraglutide, exenatide and long-acting exenatide, one of which included the oral DPP-4 inhibitor sitagliptin as a comparator. No other PRO data for DPP-4 inhibitors were identified. This review summarizes PRO data from eight clinical trials, the majority of which used the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and/or Impact of Weight on Quality of Life-Lite (IWQOL-Lite) to evaluate patient experience. People with T2DM were highly satisfied with modern incretin-based therapies compared with traditional therapies. Treatment satisfaction (including perceptions of convenience and flexibility) was high and generally higher with GLP-1 agonists in association with their greater glucose-lowering efficacy and tendency to facilitate weight loss. Weight-related quality of life (QoL) also improved in people using incretin therapies. The glycaemic improvements achieved with GLP-1 receptor agonists, coupled with the low incidence of hypoglycaemia and ability to cause weight loss, seemed to offset potential concern about injections. It is plausible that superior patient-reported benefits found in clinical trials may translate into improved, clinically meaningful, long-term outcomes through increased treatment acceptability. Long-term, prospective data are needed to ascertain whether this is the case in practice.

Abstract
INTRODUCTION The aim of this study was to measure health-related quality of life (HRQoL) in Iranian people with Type 2 Diabetes Mellitus using two different measures and examines which socio-demographic and diabetes-related characteristics are associated with better quality of life based on a nationally distributed sample. METHODS A multi-stage cluster sampling method was used to select 3472 subjects as a part of Iranian surveillance of risk factors of non-communicable disease (ISRFNCD). EuroQol-5 Dimensions questionnaire (EQ-5D) and Visual Analog Scale (VAS) were employed to measure HRQoL. Binary logistic and Tobit regression models were used to investigate factors associated with EQ-5D results. RESULTS The mean age of subjects was 59.4 years (SD = 11.7), 61.3% were female and had 8.08 years (SD = 6.7) known duration of diabetes. The patients reported "some or extreme problems" most frequently in Pain/Discomfort (69.3%) and Anxiety/Depression (56.6%) dimensions of EQ-5D. The mean EQ-5D and VAS score were 0.70 (95% CI 0.69-0.71) and 56.8 (95% CI 56.15-57.5) respectively. Female gender, lower education, unemployment, long duration of diabetes, diabetes-related hospitalization in past years and having nephropathy and lower extremity lesions were associated with higher probabilities of reporting "some or extreme problems" in most dimensions of EQ-5D in binary logistic regression models. The same factors in addition to retinopathy were significantly associated with lower levels of HRQoL in Tobit regression analysis too. CONCLUSIONS The study findings indicate that patients with diabetes in Iran suffer from relatively poor HRQoL. Therefore much more attention should be paid to main determinants of HRQoL to identify and implement appropriate policies for achieving better management of diabetes and ultimately improving the quality of life of diabetic patients in this region.

Abstract
OBJECTIVE Nearly one-half of diabetic patients have glycated hemoglobin A(1c) (HbA(1c)) levels above recommended targets. Effective physician-patient communication improves glycemia and diabetes self-care; however, communication gaps may exist that prevent patients from discussing self-care problems with treatment providers. RESEARCH DESIGN AND METHODS We assessed diabetic patients' (n = 316, 85% white, 51% female, 71% type 2 diabetes, 59 ± 11 years old, 16 ± 3 years education, 19 ± 13 years diabetes duration, and HbA(1c) = 7.9 ± 1.4%) HbA(1c), frequency of self-care, diabetes-related distress, depressive and anxiety symptoms, coping styles, diabetes quality of life, and self-care communication in the treatment relationship. Multivariate logistic regression models examined the main and interaction effects of health and psychosocial factors associated with patients' reluctance to discuss self-care. RESULTS Patients reported positive relationships with their doctors and valued honest communication; however, 30% of patients were reluctant to discuss self-care. Reluctant patients reported less frequent self-care (P = 0.05), lower diabetes quality of life (P = 0.002), and more diabetes-related distress (P = 0.001), depressive symptoms (P < 0.001), and anxiety symptoms (P = 0.001). Patients who reported elevated depressive symptoms, although not necessarily major depression, were more likely to be reluctant to discuss self-care (odds ratio [OR] 1.66 for 10-point change in t score; P < 0.001), whereas patients who were older (OR 0.78 for 10-year change; P = 0.05) and those who used more self-controlled coping styles (OR 0.78 for 10-point change; P = 0.007) were less likely to be reluctant. CONCLUSIONS Awareness of elevated depressive symptoms is important in clinical practice given that these patients may be more reluctant to discuss self-care. Interventions and evidence-based approaches are needed to improve both depressive symptoms and physician-patient communication about self-care.

Abstract
AIMS Post-hoc evaluation of relationships between first-year change in glycaemic control (HbA(1c) ) and change in patient-reported outcomes among ACCORD health-related quality of life (HRQoL) substudy participants. METHODS Data from 2053 glycaemia-trial subjects were analysed. We assessed physical and mental health status (36-Item Short Form Health Survey, Version-2), symptom count and severity (Diabetes Symptoms Distress Checklist) and treatment satisfaction (Diabetes Treatment Satisfaction Questionnaire). Linear mixed models were used to test relationships between 1-year changes in HbA(1c) and patient reported outcomes sequentially adjusting for correlates (baseline characteristics, baseline patient reported outcomes, treatment assignment, frequency of clinical contact and post-randomization weight change plus new complications). RESULTS Poorer baseline control of HbA(1c) and cardiovascular disease risk factors predicted greater one-year improvements in treatment satisfaction. Similarly, poorer baseline patient reported outcome scores all individually predicted greater 1-year improvement in that same outcome. Accounting for baseline and post-randomization characteristics and treatment arm, 1-year change in HbA(1c) was unrelated to changes in overall physical or mental health; however, every one percentage-point (10.9 mmol/mol) reduction in HbA(1c) was associated with lower symptom count (β = 0.599; P = 0.012), lower symptom distress (β = 0.051; P = 0.001), and higher treatment satisfaction (β = -2.514; P < 0.001). CONCLUSIONS Independent of all relevant covariates, better glycaemic control over 1 year was associated with reduced patient-reported diabetes symptoms and symptom distress, and increased treatment satisfaction, but not overall physical and mental health. Further investigation is required to understand the specific psychosocial mechanisms that affect how patients value health and treatments.

Abstract
BACKGROUND Clinical evidence points to patient-perceived difficulties and compliance problems in implementing early insulin therapy. Therefore, individual treatment aims are necessary to optimize diabetes therapy, as currently acknowledged by the new ADA/EASD guidelines. Better characterization of patient-perceived difficulties in the implementation of early insulin treatment may contribute to improved compliance and optimal tailoring of treatment regimens for the individual patient. OBJECTIVES To assess differences in quality of life (QoL) and patient-perceived difficulties in health care with every addition of oral hypoglycemic agents (OHAs) and insulin therapy. METHODS The analysis was conducted on a cross-sectional sample of 714 diabetic patients treated with OHAs or with insulin once or twice daily. Differences in diabetes-specific QoL, overall QoL, and perception of difficulties associated with specific diabetes treatment attributes were evaluated using trend analysis and comparisons between groups. The contribution of each diabetes treatment attribute to QoL measures and glycemic control was also assessed. RESULTS No significant differences were found in QoL measures among patients treated exclusively with OHAs when these patients were assessed by the number of oral agents, irrespective of the degree of glycemic control. Better controlled patients treated with 2 OHAs, compared with poorly controlled patients treated with a single OHA, had a lower perception of difficulties associated with diabetes treatment attributes. Poorly controlled patients treated with 2 OHAs and better controlled patients treated with 3 OHAs had similar QoL and perceived difficulties with care. However, the insulin-based alternative was consistently associated with a significantly higher perception of pain and lower overall QoL when compared with the oral regimens. Multivariate models accounted for 52% and 32% of the variance in QoL measures. CONCLUSIONS From the patients' perspective, oral therapy is the preferred strategy for attaining the treatment goals since the addition of OHAs was not associated with lower QoL or patient-perceived difficulties with care. If early insulin treatment is considered, physicians should address specific diabetes treatment characteristics, mainly the issue of pain, to promote improved QoL and disease control.

Abstract
OBJECTIVE There is an established link between health-related functioning (HRF) and cardiovascular disease (CVD) mortality, and it is known that those with diabetes predominantly die of CVD. However, few studies have determined the combined impact of diabetes and impaired HRF on CVD mortality. We investigated whether this combination carries a higher CVD risk than either component alone. RESEARCH DESIGN AND METHODS The Australian Diabetes, Obesity and Lifestyle (AusDiab) study included 11,247 adults aged ≥ 25 years from 42 randomly selected areas of Australia. At baseline (1999-2000), diabetes status was defined using the World Health Organization criteria and HRF was assessed using the SF-36 questionnaire. RESULTS Overall, after 7.4 years of follow-up, 57 persons with diabetes and 105 without diabetes had died from CVD. In individuals with and without diabetes, HRF measures were significant predictors of increased CVD mortality. The CVD mortality risks among those with diabetes or impaired physical health component summary (PCS) alone were similar (diabetes only: hazard ratio 1.4 [95% CI 0.7-2.7]; impaired PCS alone: 1.5 [1.0-2.4]), while those with both diabetes and impaired PCS had a much higher CVD mortality (2.8 [1.6-4.7]) compared with those without diabetes and normal PCS (after adjustment for multiple covariates). Similar results were found for the mental health component summary. CONCLUSIONS This study demonstrates that the combination of diabetes and impaired HRF is associated with substantially higher CVD mortality. This suggests that, among those with diabetes, impaired HRF is likely to be important in the identification of individuals at increased risk of CVD mortality.

Abstract
OBJECTIVE Testosterone levels are commonly lowered in men with diabetes, but it is unclear how these relate to symptoms of hypogonadism and quality of life. We sought to investigate the relationship between testosterone levels, symptoms of androgen deficiency, erectile function and quality of life in men with type 1 and type 2 diabetes. DESIGN AND SUBJECTS Cross-sectional study of 115 men with type 2 diabetes, 93 men with type 1 diabetes and 121 healthy controls. MEASUREMENTS Total, bioavailable and free testosterone levels were measured or calculated by Vermuelen's formula. Quality of life and symptom scores were assessed by the Audit of Diabetes Dependent Quality of Life (ADDQoL), androgen deficiency in the aging male (ADAM) and International Index of Erectile Function (IIEF) questionnaires. RESULTS Forty-five and sixty-one per cent of men with type 2 diabetes had low total and calculated free testosterone (CFT) levels, respectively. Total testosterone (TT) levels were not lowered in men with type 1 diabetes, but 32% had low CFT. After adjustment for age and waist circumference, only CFT in men with type 2 diabetes (-0·037 nm, 95% CI -0·075 to -0·0003, P = 0.048) remained lowered compared with controls. CFT correlated weakly with ADAM (r = -0·26, 95% CI -0.42 to -0·08, P = 0·006), IIEF (r = 0.19, 95% CI 0.01-0.37, P = 0.042) and ADDQoL (r = 0.21, 95% CI 0·03 to 0·38, P = 0·022) scores in men with type 2, but not type 1 diabetes. Age exerted the predominant effect on erectile function in both groups, in a model incorporating age, testosterone level and complications. CONCLUSIONS Testosterone levels are strongly affected by age and central obesity in men with type 1 and type 2 diabetes but correlate weakly with symptoms of androgen deficiency and erectile function. Testosterone levels do not appear to be a major determinant of quality of life in patients with diabetes.

Abstract
AIMS To estimate population values of health-related quality of life (HRQL) in subjects with and without Type 2 diabetes mellitus across several large population-based survey studies in Germany. Systematic differences in relation to age and sex were of particular interest. METHODS Individual data from four population-based studies from different regions throughout Germany and the nationwide German National Health Interview and Examination Survey (GNHIES98) were included in a pooled analysis of primary data (N = 9579). HRQL was assessed using the generic index instrument SF-36 (36-item Short Form Health Survey) or its shorter version, the SF-12 (12 items). Regression analysis was carried out to examine the association between Type 2 diabetes and the two component scores derived from the SF-36/SF-12, the physical component summary score (PCS-12) and the mental component summary score (MCS-12), as well as interaction effects with age and sex. RESULTS The PCS-12 differed significantly by -4.1 points in subjects with Type 2 diabetes in comparison with subjects without Type 2 diabetes. Type 2 diabetes was associated with significantly lower MCS-12 in women only. Higher age was associated with lower PCS-12, but with an increase in MCS-12, for subjects with and without Type 2 diabetes. CONCLUSIONS Pooled analysis of population-based primary data offers HRQL values for subjects with Type 2 diabetes in Germany, stratified by age and sex. Type 2 diabetes has negative consequences for HRQL, particularly for women. This underlines the burden of disease and the importance of diabetes prevention. Factors that disadvantage women with Type 2 diabetes need to be researched more thoroughly.

Abstract
As a common side effect of insulin treatment for diabetes, hypoglycaemia is a constant threat and can have far-reaching and potentially devastating consequences, including immediate physical injury as well as more pervasive cognitive, behavioural and emotional effects. Moreover, as a significant limiting factor in achieving optimal glycaemic control, exposure to hypoglycaemia can influence diabetes self-management. Although hypoglycaemia is known to occur in Type 2 diabetes, its morbidity and impact on the individual are not well recognized. The aim of the current review is to examine published evidence to achieve a synthesis of the scope and significance of the potential detriment caused by hypoglycaemia to individuals with Type 2 diabetes. The implications of these observations for treatment and research have also been considered. A narrative review was performed of empirical papers published in English since 1966, reporting the effect of hypoglycaemia on quality of life and related outcomes (including generic and diabetes-specific quality of life, emotional well-being and health utilities) in Type 2 diabetes. Research demonstrates the potential impact of hypoglycaemia on the lives of people with Type 2 diabetes, from an association with depressive symptoms and heightened anxiety, to impairment of the ability to drive, work and function in ways that are important for quality of life. Few studies consider hypoglycaemia as an explanatory variable in combination with quality of life or related primary endpoints. As a consequence, there is a pressing need for high-quality research into the overall impact of hypoglycaemia on the lives of people with Type 2 diabetes.

Abstract
BACKGROUND The need for an approach to measuring health results that incorporates patients' and payers' perspectives has generated a wide range of health care outcomes (HCOs), but it is yet unknown whether these HCOs are appropriate or valid for the health care decision-making process. OBJECTIVE The goal of this study was to assess HCOs, patient-reported outcomes (PROs), and economic outcomes in terms of validity and appropriateness to health care decision making in type 2 diabetes mellitus (T2DM). METHODS This systematic review of studies published between January 1, 1996, and November 1, 2010, comprised an electronic literature search of MEDLINE and Centre for Reviews and Dissemination databases. Studies included were clinical trials, observational studies, economic analyses, and studies on the development and validation of HCOs in T2DM in the adult population. HCOs were assessed and classified according to their relevance for decision makers in terms of feasibility for routine use, validity, sensitivity, reliability, understanding, and scope. RESULTS Two independent reviewers screened 4497 citations. Of these, 281 potentially eligible full articles were retrieved, and 185 met the inclusion criteria. A total of 121 HCOs in T2DM were identified: 80 (66.1%) PROs and 41 (33.9%) economic outcomes. Only 44.6% of the outcomes assessed were appropriate and valid for health care decision making. Greater deficiencies in evidence were found for PROs (61.3%), followed by economic outcomes (43.9%). CONCLUSIONS A large number of HCOs are being used in the health care decision-making process, but a significant proportion of these new outcomes have not been properly validated. Despite the fact that appropriate measures will depend on the specific needs of the decision makers, researchers need to use HCOs for which evidence of quality and appropriateness is available.

Abstract
Background Diabetes mellitus is a major global public health threat. In Australia, as elsewhere, it is responsible for a sizeable portion of the overall burden of disease, and significant costs. The psychological and social impact of diabetes on individuals with the disease can be severe, and if not adequately addressed, can lead to the worsening of the overall disease picture. The Living With Diabetes Study aims to contribute to a holistic understanding of the psychological and social aspects of diabetes mellitus. Methods/Design The Living With Diabetes Study is a 5-year prospective cohort study, based in Queensland, Australia. The first wave of data, which was collected via a mailed self-report survey, was gathered in 2008, with annual collections thereafter. Measurements include: demographic, lifestyle, health and disease characteristics; quality of life (EQ-5D, ADDQoL); emotional well-being (CES-D, LOT-R, ESSI); disease self-management (PAM); and health-care utilisation and patient-assessed quality of care (PACIC). 29% of the 14,439 adults who were invited to participate in the study agreed to do so, yielding a sample size of 3,951 people. Discussion The data collected by the Living With Diabetes Study provides a good representation of Australians with diabetes to follow over time in order to better understand the natural course of the illness. The study has potential to further illuminate, and give a comprehensive picture of the psychosocial implications of living with diabetes. Data collection is ongoing.

BACKGROUND Few qualitative studies of simultaneous pancreas-kidney transplantation (SPK Tx) have been published. The aims of this study were to explore from the perspective of patients, the experience of living with diabetes mellitus type 1 (T1DM), suffering from complications, and undergoing SPK Tx with good outcome; and to determine the impact of SPK Tx on patients and their social and cultural environment. METHODS We performed a focused ethnographic study. Twenty patients were interviewed. Data were analyzed using content analysis and constant comparison following the method proposed by Miles and Huberman. RESULTS A functioning SPK Tx allowed renal replacement therapy and insulin to be discontinued. To describe their new situation, patients used words and phrases such as "miracle", "being reborn" or "coming back to life". Although the complications of T1DM, its surgery and treatment, and associated psychological problems did not disappear after SPK Tx, these were minimized when compared with the pretransplantation situation. CONCLUSION For patients, SPK Tx represents a recovery of their health and autonomy despite remaining problems associated with the complications of T1DM and SPK Tx. The understanding of patients' existential framework and their experience of disease are key factors for planning new intervention and improvement strategies.

Abstract
BACKGROUND The goal of this project is to evaluate the implementation of an integrated and interdisciplinary program for prevention and management of cardiometabolic risk (PCMR). The intervention is based on the Chronic Care Model. The study will evaluate the implementation of the PCMR in 6 of the 12 health and social services centres (CSSS) in Montréal, and the effects of the PCMR on patients and the practice of their primary care physicians up to 40 months following implementation, as well as the sustainability of the program. Objectives are: 1-to evaluate the effects of the PCMR and their persistence on patients registered in the program and the practice of their primary care physicians, by implementation site and degree of exposure to the program; 2-to assess the degree of implementation of PCMR in each CSSS territory and identify related contextual factors; 3-to establish the relationships between the effects observed, the degree of PCMR implementation and the related contextual factors; 4-to assess the impact of the PCMR on strengthening local services networks. METHODS/DESIGN The evaluation will use a mixed design that includes two complementary research strategies. The first strategy is similar to a quasi-experimental "before-after" design, based on a quantitative approach; it will look at the program's effects and their variations among the six territories. The effects analysis will use data from a clinical database and from questionnaires completed by participating patients and physicians. Over 3000 patients will be recruited. The second strategy corresponds to a multiple case study approach, where each of the six CSSS constitutes a case. With this strategy, qualitative methods will set out the context of implementation using data from semi-structured interviews with program managers. The quantitative data will be analyzed using linear or multilevel models complemented with an interpretive approach to qualitative data analysis. DISCUSSION Our study will identify contextual factors associated with the effectiveness, successful implementation and sustainability of such a program. The contextual information will enable us to extrapolate our results to other contexts with similar conditions. TRIAL REGISTRATION ClinicalTrials.gov: NCT01326130.

Abstract
PURPOSE This study aims to analyse the psychometric properties of the most recent 19 item version of the Audit of Diabetes-Dependent Quality of Life (ADDQoL) in a large, population-based sample of adults living in Australia. METHODS A total of 3,951 people living with diabetes completed the ADDQoL as part of the Living With Diabetes Study. Data analysis investigated the feasibility of using the ADDQoL in a large, population-based survey; internal consistency; adherence to a single-factor structure; and convergent/discriminant validity. RESULTS Data support the feasibility of using the ADDQoL in population-based survey research. Although a strict single-factor structure for the ADDQoL was not demonstrated, the results overall support an interpretation of essential unidimensionality. A validation matrix provides support for the convergent and divergent validity of the measure, as does the ADDQoL's ability to discriminate between respondents based on insulin dependence and complications. CONCLUSIONS The ADDQoL has good psychometric properties and provides clinicians and researchers with a useful tool for comprehensively assessing quality of life in adults with diabetes.

Abstract
AIM This study was intended to cross-culturally adapt and evaluate the Chinese version of the Audit of Diabetes Dependent Quality of Life (ADDQoL)--the Chinese Normal Audit of Diabetes-Dependent Quality of Life (CN-ADDQoL) in Mainland, China. METHODS The standard procedure for cross-culture adaptation was used to develop the Chinese version CN-ADDQoL. After the linguistic validation, the validity and reliability of CN-ADDQoL questionnaire were evaluated based on a sample of 697 Type 2 diabetes patients. The Cronbach's α coefficient, correlation analysis and the structural equation model (SEM) were applied, respectively. RESULTS We developed 19 items for the CN-ADDQoL questionnaire. The estimated Cronbach's α coefficient was 0.941, indicating an excellent internal consistency of the scale. All items had high performance in the structural validity evaluation, with most factor loading values being larger than 0.40 (varied from 0.44 to 0.88). CONCLUSIONS The Chinese version CN-ADDQoL has maintained its original psychometric properties and achieved adequate reliability and validity. Therefore, it could be efficiently used to evaluate the current trend of diabetes self-management education programs and multinational clinical research trials.

Abstract
BACKGROUND Multimorbidity in the older population is well acknowledged to negatively affect health-related quality of life (HRQL). Several studies have examined the independent effects of single diseases; however, little research has focused on interaction between diseases. The purpose of this study was to assess the impact of six self-reported major conditions and their combinations on HRQL measured by the EQ-5D. METHODS The EQ-5D was administered in the population-based KORA-Age study of 4,565 Germans aged 65 years or older. A generalised additive regression model was used to assess the effects of chronic conditions on HRQL and to account for the nonlinear associations with age and body mass index (BMI). Disease interactions were identified by a forward variable selection method. RESULTS The conditions with the greatest negative impact on the EQ-5D index were the history of a stroke (regression coefficient -11.3, p < 0.0001) and chronic bronchitis (regression coefficient -8.1, p < 0.0001). Patients with both diabetes and coronary disorders showed more impaired HRQL than could be expected from their separate effects (coefficient of interaction term -8.1, p < 0.0001). A synergistic effect on HRQL was also found for the combination of coronary disorders and stroke. The effect of BMI on the mean EQ-5D index was inverse U-shaped with a maximum at around 24.8 kg/m². CONCLUSIONS There are important interactions between coronary problems, diabetes mellitus, and the history of a stroke that negatively affect HRQL in the older German population. Not only high but also low BMI is associated with impairments in health status.

Abstract
BACKGROUND The EQ-5D is a generic preference-based health status measure that has been widely applied to measure the impact of Type 2 diabetes mellitus. This review summarizes evidence on the validity, reliability and responsiveness of the EQ-5D in studies of Type 2 diabetes and provides a catalogue of EQ-5D index scores for Type 2 diabetes and various complications and subgroups. METHODS A structured search was conducted (1987-2009) using keywords relevant to Type 2 diabetes and the EQ-5D. Original research studies in Type 2 diabetes that reported EQ-5D results and/or measurement properties were included. RESULTS Of the 59 included articles, 54 publications reported EQ-5D responses and 39 papers presented evidence on the measurement properties of the EQ-5D. Studies that reported measurement properties supported construct, convergent and discriminant validity, test-retest reliability and responsiveness of the EQ-5D in Type 2 diabetes. Several studies reported a ceiling effect for the EQ-5D and an inability to capture multiple complications was observed. EQ-5D index scores ranged from 0.20 (severe diabetic peripheral neuropathic pain) to 0.88 (general population: good HbA(1c) level). For six subgroups, sufficient studies were available to calculate pooled mean index scores (95% CI): general population 0.67 (0.59-0.75), no complications 0.76 (0.68-0.83), microvascular complications 0.73 (0.57-0.89), macrovascular complications 0.73 (0.57-0.88), diabetic peripheral neuropathic pain 0.45 (0.39-0.51) and retinopathy 0.57 (0.46-0.69). CONCLUSIONS Evidence supported validity, reliability and responsiveness of the EQ-5D in Type 2 diabetes. EQ-5D index scores associated with Type 2 diabetes and various complications can be useful for modelling health outcomes in economic evaluations of health programmes for Type 2 diabetes.

Abstract
With the increasing prominence of the patients' involvement in the care they receive, the assessment of outcomes based on the patient's perspective using patient-reported outcome measures (PROMs), are increasingly accompanying the traditional clinical ways of measuring health and the effects of treatment on the patient. This article provides an overview as to what PROMs are and the different health constructs they are purported to measure. Differences between generic and disease-specific, multidimensional and index scored PROMs are also described. Factors relating to the choice of a PROM are discussed with a particular focus on the importance of developing a measurement strategy and endpoint model to ensure the appropriate PROM is selected to measure the desired outcome. Examples of the application of PROMs are given together with some of the methodological approaches to interpreting PROM data. Finally, issues on maximizing the benefits of using PROMs are briefly discussed.

Abstract
Nondigital lower extremity ulcers are a difficult to treat
complication of scleroderma, and a significant cause of morbidity.
The purpose of this study was to evaluate the prevalence of
nondigital lower extremity ulcers in scleroderma and describe the
associations with autoantibodies and genetic prothrombotic states.
A cohort of 249 consecutive scleroderma patients seen in the
Georgetown University Hosptial Division of Rheumatology was
evaluated, 10 of whom had active ulcers, giving a prevalence of
4.0%. Patients with diffuse scleroderma had shorter disease
duration at the time of ulcer development (mean 4.05 years ± 0.05)
compared to those with limited disease (mean 22.83 years ± 5.612, P value .0078).
Ulcers were bilateral in 70%. In the 10 patients
with ulcers, antiphospholipid antibodies were positive in 50%,
and genetic prothrombotic screen was positive in 70% which is
higher than expected based on prevalence reports from the general
scleroderma population. Of patients with biopsy specimens
available (n = 5), fibrin occlusive vasculopathy was seen in 100%,
and all of these patients had either positive antiphospholipid
antibody screen, or positive genetic prothrombotic profile. We
recommend screening scleroderma patients with lower extremity
ulcers for the presence of anti-phospholipid antibodies and
genetic prothrombotic states.

Abstract
Background The aim of this study was to describe how diabetes complications influence the health-related quality of life of individuals with diabetes using the individual EQ-5D dimensions and the EQ-5D index. Methods We mailed a questionnaire to 1,000 individuals with diabetes type 1 and 2 in Norway. The questionnaire had questions about socio-demographic characteristics, use of health care, diabetes complications and finally the EQ-5D descriptive system. Logistic regressions were used to explore determinants of responses in the EQ-5D dimensions, and robust linear regression was used to explore determinants of the EQ-5D index. Results In multivariate analyses the strongest determinants of reduced MOBILITY were neuropathy and ischemic heart disease. In the ANXIETY/DEPRESSION dimension of the EQ-5D, "fear of hypoglycaemia" was a strong determinant. For those without complications, the EQ-5D index was 0.90 (type 1 diabetes) and 0.85 (type 2 diabetes). For those with complications, the EQ-5D index was 0.68 (type 1 diabetes) and 0.73 (type 2 diabetes). In the linear regression the factors with the greatest negative impact on the EQ-5D index were ischemic heart disease (type 1 diabetes), stroke (both diabetes types), neuropathy (both diabetes types), and fear of hypoglycaemia (type 2 diabetes). Conclusions The EQ-5D dimensions and the EQ-5D seem capable of capturing the consequences of diabetes-related complications, and such complications may have substantial impact on several dimensions of health-related quality of life (HRQoL). The strongest determinants of reduced HRQoL in people with diabetes were ischemic heart disease, stroke and neuropathy.

Abstract
The relationships between co-morbid depression in people with diabetes and adverse outcomes including poor HbA(1c) control, adherence to medication and mortality have been examined and confirmed. However, as the awareness of the decrement to health-related quality of life (HRQOL) in people with diabetes and its clinical consequences grows, investigators have become increasingly interested in measuring HRQOL in clinical trials. Given that the psychological factors such as depression may contribute to diminished HRQOL, the present review sought to summarize the association between these variables in people with type 2 diabetes. Articles for a systematic review were obtained via a search performed using MEDLINE, EMBASE and PsycINFO (1980-2007).Fourteen articles fulfilled the inclusion criteria. Studies indicated that self-reported depressive symptoms markedly impaired HRQOL on several domains. However, depression was not related to all sub-domains of HRQOL in all studies, suggesting that the effects of depression on certain aspects of HRQOL may vary between clinical and demographic subgroups. Although a number of shortcomings identified in the current literature should be taken into account for future research, the importance of this review lies in the possibility it raises that the improvements in HRQOL and clinical practice may potentially be achieved by placing greater attention on the identification and management of depression.
