- Purpose The Swedish National Diabetes Register (NDR) has developed a diabetes-specific questionnaire to collect information on individuals' management of their diabetes, collaboration with healthcare providers and the disease’s impact on daily life. Our main objective was to develop measures of well-being, abilities to manage diabetes and judgements of diabetes care, and to detect and quantify differences using the NDR questionnaire.Design, setting and participants The questionnaire was analysed with using responses from 3689 participants with type 1 and 2 diabetes, randomly sampled from the NDR population, combined with register data on patient characteristics and cardiovascular and diabetes complication risk factors.Methods We used item response theory to develop scales for measuring well-being, abilities to manage diabetes and judgements of diabetes care (scores). Test–retest reliability on the scale level was analysed with intraclass correlation. Associations between scores and risk factor levels were investigated with subgroup analyses and correlations.Results We obtained scales with satisfactory measurement properties, covering patient reported outcome measures such as general well-being and being free of worries, and patient reported experience measure, for example, access and continuity in diabetes care. All scales had acceptable test–retest reliability and could detect differences between diabetes types, age, gender and treatment subgroups. In several aspects, for example, freedom of worries, type 1 patients report lower than type 2, and younger patients lower than older. Associations were found between some scores and glycated haemoglobin, but none with systolic blood pressure or low-density lipoprotein cholesterol. Clinicians report positive experience of using scores, visually presented, in the patient dialogue.Conclusions The questionnaire measures and detects differences in patient well-being, abilities and judgements of diabetes care, and identifies areas for improvement. To further improve diabetes care, we conclude that patient-reported measures are important supplements to cardiovascular and diabetes complication risk factors, reflecting patient experiences of living with diabetes and diabetes care.

- Objectives: To estimate risks of fatal/nonfatal coronary heart disease (CHD), stroke and cardiovascular disease (CVD) with SBP in an observational study of patients with type 2 diabetes. Methods: Twelve thousand, six hundred and seventy-seven patients aged 30–75 years, treated with antihypertensive drugs, without previous congestive heart failure, followed for 5 years. Results: Risk curves of CHD and stroke increased progressively with higher baseline or updated mean SBP in a Cox model, in all participants, and in two subgroups without (n = 10 304) or with (n = 2373) a history of CVD, with no J-shaped risk curves at low SBP levels. Hazard ratios for CHD and stroke per 10-mmHg increase in updated mean SBP in all participants, adjusting for clinical characteristics and traditional risk factors, were 1.08 (1.04–1.13) and 1.20 (1.13–1.27), P < 0.001. With updated mean SBP of 110–129 mmHg as reference, SBP of at least 140 mmHg showed risk increases of 37% for CHD, 86% for stroke and 44% for CVD (P = 0.001 to <0.001), whereas SBP of 130–139 mmHg showed nonsignificant risk increases for these outcomes. With baseline SBP of 110–129 mmHg, CHD and CVD risks increased with further SBP reduction, hazard ratios were 1.77 and 1.73 (P = 0.002), but decreased considerably for CHD, stroke and CVD with higher baseline SBP. Conclusion: Risks of CHD and stroke increased progressively with higher SBP, with no J-shaped curves, although risk increase was significant only for SBP of at least 140 mmHg, but not comparing 130–139 and 110–129 mmHg. Additionally, baseline SBP of 110–129 mmHg showed increased CHD and CVD risk with further SBP reduction during follow-up, whereas baseline SBP of at least 130 showed benefits.

- We assessed blood pressure (BP) trends in patients with type 2 diabetes from a national diabetes register using three cross-sectional samples (aged 30?85 years) in 2005, 2007 and 2009, and in patients from 2005 followed individually until 2009. The prevalence of hypertension was 87% among all 180 369 patients in 2009, although lower in subgroups with ages 30?39, 40?49 and 50?59 years: 40%, 60% and 77%. In the three cross-sectional surveys, mean BP decreased (141/77?136/76 mmHg), uncontrolled BP? 140/90 mmHg decreased (58?46%), and antihypertensive drug treatment (AHT) increased (73?81%). Comparatively in 79 185 patients followed individually for 5 years, mean BP decreased (141/77?137/75 mmHg), uncontrolled BP ?140/90 mmHg decreased (58?47%) and AHT increased (73?82%). Independent predictors of BP decrease were BMI decrease (stronger) and increase in AHT. AHT occurred among 81% of all patients in 2009. In 57 645 patients on AHT followed individually, mean BP decreased (143/77?138/75 mmHg) and uncontrolled BP ?140/90 mmHg decreased (63?50%). Among 5164 patients with nephropathy on AHT followed individually, BP <130/80 mmHg increased (12?21%). In conclusion, BP control improved from 2005 to 2009, relative to BMI decrease and AHT increase, although still about half had BP ?140/90 mmHg.

Implementing the Digital Diabetes Questionnaire as a clinical tool in routine diabetes care : Focus group discussions with patients and health care professionals
- 2022

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The Diabetes Questionnaire is a digital patient-reported outcome and experience measure for adults living with diabetes. The Diabetes Questionnaire is intended for use in routine clinical visits in diabetes care and to enable patient perspectives to be integrated into the Swedish National Diabetes Register. The Diabetes Questionnaire was developed on the basis of patients' perspectives, and evidence for its measurement qualities has been demonstrated. Patients receive an invitation to complete the questionnaire before clinical visits, and the patient and health care professional (HCP) can discuss the findings, which are instantly displayed during the visit. Implementation processes for new tools in routine care need to be studied to understand the influence of contextual factors, the support needed, and how patients and HCPs experience clinical use.OBJECTIVE: The aim of this study was to describe patients' and HCPs' experiences of initiating the use of the digital Diabetes Questionnaire as a clinical tool in routine diabetes care, supported by a structured implementation strategy involving initial education, local facilitators, and regular follow-ups.METHODS: In this qualitative study, semistructured focus group discussions were conducted 12 months after the use of the Diabetes Questionnaire was initiated. Participants were diabetes specialist nurses and physicians (20 participants in 4 groups) at hospital-based outpatient clinics or primary health care clinics and adults with type 1 or type 2 diabetes (15 participants in 4 groups). The audiotaped transcripts were analyzed using inductive qualitative content analysis.RESULTS: The results revealed 2 main categories that integrated patients' and HCPs' experiences, which together formed an overarching theme: While implementation demands new approaches, the Diabetes Questionnaire provides a broader perspective. The first main category (The Diabetes Questionnaire supports person-centered clinical visits) comprised comments expressing that the digital Diabetes Questionnaire can initiate and encourage reflection in preparation for clinical visits, bring important topics to light during clinical visits, and broaden the scope of discussion by providing additional information. The second main category (The process of initiating the implementation of the Diabetes Questionnaire) comprised comments that described differences in engagement among HCPs and their managers, challenges of establishing new routines, experiences of support during implementation, thoughts about the Diabetes Questionnaire, need to change local administrative routines, and opportunities and concerns for continued use.CONCLUSIONS: The Diabetes Questionnaire can broaden the scope of health data in routine diabetes care. While implementation demands new approaches, patients and HCPs saw potential positive impacts of using the questionnaire at both the individual and group levels. Our results can inform further development of implementation strategies to support the clinical use of the questionnaire.

- Aims: This study assessed hemoglobin A1c (HbA1c) across the lifespan in people with type 1 diabetes (T1D) in Germany/Austria, Sweden, and the United States between 2011 and 2017 to ascertain temporal and age-related trends. Methods: Data from the Diabetes-Patienten-Verlaufsdokumentation (DPV) (n = 25,651 in 2011, n = 29,442 in 2017); Swedish Pediatric Diabetes Quality Registry (SWEDIABKIDS)/National Diabetes Register (NDR), (n = 44,474 in 2011, n = 53,690 in 2017); and T1D Exchange (n = 16,198 in 2011, n = 17,087 in 2017) registries were analyzed by linear regression to compare mean HbA1c overall and by age group. Results: Controlling for age, sex, and T1D duration, HbA1c increased in the United States between 2011 and 2017, decreased in Sweden, and did not change in Germany/Austria. Controlling for sex and T1D duration, mean HbA1c decreased between 2011 and 2017 in all age cohorts in Sweden (P < 0.001). In the United States, HbA1c stayed the same for participants <6 years and 45 to <65 years and increased in all other age groups (P < 0.05). In Germany/Austria, HbA1c stayed the same for participants <6 to <13 years and 18 to <25 years; decreased for participants ages 13 to <18 years (P < 0.01); and increased for participants >= 25 years (P < 0.05). Conclusions: The comparison of international trends in HbA1c makes it possible to identify differences, explore underlying causes, and share quality improvement processes. National quality improvement initiatives are well accepted in Europe but have yet to be implemented systematically in the United States. However, disparities created by the lack of universal access to health care coverage, unequal access to diabetes technologies (e.g., continuous glucose monitoring) regardless of insurance status, and high out-of-pocket cost for the underinsured ultimately limit the potential of quality improvement initiatives.

Tidskriftsartikel (refereegranskat)abstract
- Background A chronic disease impacts a patient's daily life, with the burden of symptoms and managing the condition, and concerns of progression and disease complications. Such aspects are captured by Patient-Reported Outcomes Measures (PROM), assessments of e.g. wellbeing. Patient-Reported Experience Measures (PREM) assess patients' experiences of healthcare and address patient preferences. Biomarkers are useful for monitoring disease activity and treatment effect and determining risks of progression and complications, and they provide information on current and future health. Individuals may differ in which among these aspects they consider important. We aimed to develop a measure of quality of life using biomarkers, PROM and PREM, that would provide an unambiguous ranking of individuals, without presuming any specific set of importance weights. We anticipated it would be useful for studying needs and room for improvement, estimating the effects of interventions and comparing alternatives, and for developing healthcare with a broad focus on the individual. We wished to examine if efficiency analysis could be used for this purpose, in an application to individuals with type 1 diabetes. Results We used PROM and PREM data linked to registry data on risk factors, in a large sample selected from the National Diabetes Registry in Sweden. Efficiency analysis appears useful for evaluating the situation of individuals with type 1 diabetes. Quality of life was estimated as efficiency, which differed by age. The contribution of different components to quality of life was heterogeneous, and differed by gender, age and duration of diabetes. Observed quality of life shortfall was mainly due to inefficiency, and to some extent due to the level of available inputs. Conclusions The efficiency analysis approach can use patient-reported outcomes measures, patient-reported experience measures and comorbidity risk factors to estimate quality of life with a broad focus on the individual, in individuals with type 1 diabetes. The approach enables ranking and comparisons using all these aspects in parallel, and allows each individual to express their own view of which aspects are important to them. The approach can be used for policy regarding interventions on inefficiency as well as healthcare resource allocation, although currently limited to type 1 diabetes.

- OBJECTIVE Patients with diabetes or familial hypercholesterolemia (FH) have an increased incidence of cardiovascular diseases compared with the population, but whether this risk is exacerbated in patients with combined traits is unknown. RESEARCH DESIGN AND METHODS In this Swedish nationwide, register-based cohort study, patients with diabetes were included between 2002 and 2020. Adjusted Cox proportional hazards models were used to assess the risk of cardiovascular events in patients with or without phenotypic FH (‡6 points for phenotypic FH according to Dutch Lipid Clinic Network criteria) compared with general population control subjects without diabetes as reference. RESULTS A total of 45,585 patients with type 1 diabetes (227,923 control subjects) and 655,250 patients with type 2 diabetes (655,250 control subjects) were followed for a median of 14.1 and 7.9 years, respectively. Of those, 153 and 7,197, respectively, had phenotypic FH. Compared with control subjects, patients with diabetes and phenotypic FH had higher risk of cardiovascular mortality (type 1: Hazard ratio 21.3 [95% CI 14.6-31.0]; type 2: 2.40 [2.19-2.63]) and of a cardiovascular event (type 1: 15.1 [11.1-20.5]; type 2: 2.73 [2.58-2.89]). Further, patients with diabetes and phenotypic FH had higher LDL-cholesterol levels during observation (P < 0.05) and increased risk of all major cardiovascular outcomes (P < 0.0001) than patients with diabetes but without FH. The proportion receiving lipid-lowering treatment was higher in patients with phenotypic FH (P < 0.0001). CONCLUSIONS Patients with both diabetes and phenotypic FH are more at risk for adverse cardiovascular outcomes and have higher LDL-cholesterol levels despite receiving intensified lipid-lowering therapy.

- Aims: We assessed the association between risk factors and cardiovascular disease in an observational study of patients with Type 1 diabetes from the Swedish National Diabetes Register.Methods: A derivation sample of 3661 patients, aged 30-65 years, 6.1% with previous cardiovascular disease, baseline 2002, and 197 cardiovascular disease events when followed for 5 years until 2007. A separate validation data set of 4484 patients, baseline 2003, 201 cardiovascular disease events when followed for 4 years.Results: Adjusted hazard ratios at Cox regression for fatal/non-fatal cardiovascular disease were: diabetes duration 2.76 (2.21-3.44); onset age 1.47 (1.21-1.78); log ratio total cholesterol:HDL cholesterol 1.26 (1.09-1.45); log HbA(1c) 1.19 (1.03-1.38); log systolic blood pressure 1.17 (1.01-1.34) (1 SD increase in continuous variables); smoker 1.76 (1.27-2.46); macroalbuminuria (> 200 mu g/min) 1.52 (1.10-2.10); previous cardiovascular disease 3.51 (2.54-4.84). All eight variables were used to elaborate a risk equation for 5-year cardiovascular disease risk. Regarding calibration in the derivation data set, ratio predicted 5-year risk (mean 5.4 +/- 7.9%) to observed event rate was 1.0. Discrimination was sufficient, with C-statistic 0.83, sensitivity and specificity 72 and 77%, respectively, for the top quartile of predicted risk. Similarly, calibration and discrimination were adequate in the validation data set: ratio of predicted 4-year risk/observed rate 0.94, C-statistic 0.80, sensitivity and specificity 62 and 77%, respectively, for the top quartile.Conclusions: This 5-year cardiovascular disease risk model from a large observational study of patients with Type 1 diabetes in routine care showed adequate calibration and discrimination and can be useful for clinical practice. It should also be tested in patients with Type 1 diabetes from other countries.

- Objectives: Estimate risks of coronary heart disease (CHD), stroke and cardiovascular disease (CVD) with updated mean systolic (SBP) and diastolic (DBP) blood pressure in an observational study of patients with type 2 diabetes. Methods: Thirty-five thousand and forty-one patients treated with antihypertensive drugs, and 18 512 untreated patients, aged 30-75 years, without previous heart failure, followed for 6 years until 2009. Results: In treated patients, nonlinear splines for 6-year risk of fatal/nonfatal CHD, stroke and CVD by BP as a continuous variable showed a progressive increase with higher SBP from 140 mmHg and higher, and with DBP from 80 mmHg, with a J-shaped risk curve at lowest SBP levels, but not obviously at lowest DBP levels. Analysing intervals of SBP with 130-134 mmHg as reference at Cox regression, adjusted hazard ratios (HR) for fatal/nonfatal CHD, stroke and CVD with at least 140 mmHg were 1.22 [95% confidence interval (CI): 1.08-1.39], 1,43 (1.18-1.72), 1.26 (1.13-1.41), all P<0.001. HR with 115-129 and 135-139 mmHg were nonsignificant, whereas increased with 100-114 mmHg, 1.96 (P<0.001), 1.75 (P=0.02), 2.08 (P < 0.001), respectively. With DBP 75-79 mmHg as reference, adjusted HR for fatal/nonfatal CHD, stroke and CVD with DBP 80-84 mmHg were 1.42 (1.26-1.59), 1.46 (1.24-1.72), 1.39 (1.26-1.53), all P< 0.001. Corresponding HR with DBP at least 85 mmHg were 1.70 (1.50-1.92), 2.35 (1.99-2.77), 1..87 (1.69-2.07), all P < 0.001. Corresponding HR with DBP 60-69 and 70-74 mmHg were nonsignificant. The picture was similar in 7059 patients with previous CVD and in untreated patients. Conclusion: BP around 130-135/75-79 mmHg showed lower risks of cardiovascular diseases in patients with type 2 diabetes.

- OBJECTIVE: Type 2 diabetes has been associated with high dementia risk. However, the links to different dementia subtypes is unclear. We examined to what extent type 2 diabetes is associated with dementia subtypes and whether such associations differed by glycemic control. RESEARCH DESIGN AND METHODS: We used data from the Swedish National Diabetes Register and included 378,299 patients with type 2 diabetes and 1,886,022 control subjects matched for age, sex, and county randomly selected from the Swedish Total Population Register. The outcomes were incidence of Alzheimer disease, vascular dementia, and nonvascular dementia. The association of type 2 diabetes with dementia was stratified by baseline glycated hemoglobin (HbA1c) in patients with type 2 diabetes only. Cox regression was used to study the excess risk of outcomes. RESULTS: Over the follow-up (median 6.8 years), dementia developed in 11,508 (3.0%) patients with type 2 diabetes and 52,244 (2.7%) control subjects. The strongest association was observed for vascular dementia, with patients with type 2 diabetes compared with control subjects having a hazard ratio [HR] of 1.34 (95% CI 1.28, 1.41). The association of type 2 diabetes with nonvascular dementia was more modest (HR 1.10 [95% CI 1.07, 1.13]). However, risk for Alzheimer disease was lower in patients with type 2 diabetes than in control subjects (HR 0.94 [95% CI 0.90, 0.99]). When the analyses were stratified by circulating concentrations of HbA1c, a dose-response association was observed. CONCLUSIONS: The association of type 2 diabetes with dementia differs by subtypes of dementia. The strongest detrimental association is observed for vascular dementia. Moreover, patients with type 2 diabetes with poor glycemic control have an increased risk of developing vascular and nonvascular dementia. © 2022 by the American Diabetes Association.

Tidskriftsartikel (refereegranskat)abstract
- Introduction Renal complications are both a marker of previous suboptimal glycaemic control and a major risk factor for cardiovascular disease in persons with type 1 diabetes (T1D). The aim of the study was to evaluate the prevalence of renal complications in persons with T1D in four geographical regions. Methods Nationwide registry data from Austria/Germany, Sweden and the US were used to estimate the prevalence of renal complications from January 2016 until September 2018. Chronic kidney disease (CKD) and albuminuria in the study population and each registry were analysed by diabetes duration. Risk factors for renal complications were described by registry. Results In the total cohort of 78.926 adults with T1D, mean age was 44.4 +/- 18.43 years and mean diabetes duration was 21.6 +/- 22 years. Mean estimated glomerular filtration rate (eGFR) was 94.0 +/- 31.45 ml/min, 13.0% had microalbuminuria and 3.9% had macroalbuminuria. Mean age, diabetes duration, use of insulin pumps and continuous glucose monitoring, as well as presence of albuminuria, varied between registries. Albuminuria was present in approximately 10% of persons with diabetes duration < 20 years and impaired renal function (eGFR < 60 ml/min) was present in 17%. In persons with diabetes duration > 40 years, approximately one-third had albuminuria and 25% had impaired renal function. Conclusions This analysis used three nationwide registries of persons with T1D. Despite recent use of more effective diabetes therapies, a substantial proportion of persons with T1D have renal complications at < 20 years after diagnosis. Efficient glucose-lowering and renal-protective strategies are needed in persons with T1D.

Cardiovaskular risk factors and complications in type 1 and type 2 diabetes
- 2010

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Patients with diabetes have increased risk of cardiovascular disease (CVD) and mortality compared to the general population. The aim of this work was to describe the clinical characteristics and risk factors in patients with type 1 diabetes, and also to investigate the association between glycaemic control and CVD in type 1 and type 2 diabetes, and to analyse the association between BMI, overweight and obesity, and CVD in type 2 diabetes. These observational studies comprise patients from the Swedish National Diabetes Register (NDR). Clinical characteristics and risk factor control in type 1 diabetes were analysed in two cross-sectional samples, in 1997 and 2004. 7454 patients with type 1 diabetes were followed from 2002/03 to 2007, and 13,087 patients (Study III) and 18,336 (Study IV) with type 2 diabetes were followed from 1997/98 to 2003, regarding fatal/non-fatal CVD events. Cox proportional hazard models were used to estimate adjusted hazard ratios with 95% confidence intervals and to estimate 5- and 6-year event rates for the outcomes. In patients with type 1 diabetes slight but significant improvements were seen in glycaemic control, blood pressure and lipid levels from 1997 to 2004. Hazard ratios for coronary heart disease (CHD) and CVD per 1%-unit increase in baseline HbA1c were 1.31 and 1.26 (p<0.001), respectively, when adjusted for age, sex, duration of diabetes and cardiovascular risk factors. Adjusted 5-year event rates of CHD and CVD increased progressively with higher HbA1c levels. Patients with HbA1c levels of 5-7.9% (mean 7.2%) at baseline had about 40% lower risk for CHD and CVD, compared with patients with HbA1c 8-11.9% (mean 9.0%). In type 2 diabetes adjusted hazard ratios for a 5-unit increase in BMI were 1.15 for first-incident CHD and 1.13 for CVD. Obesity was associated with a 44% increase in risk of CVD, and overweight with a 24% increase in risk, compared with normal weight. Adjusted hazard ratios for a 1%-unit increase in HbA1c were 1.11 for CHD and 1.10 for CVD (p<0.001), and the corresponding adjusted 6-year event rates for these outcomes increased progressively with higher baseline and updated mean HbA1c values, also when sub-grouping the data by duration, previous CVD or hypoglycaemic treatment. A group of patients with a mean baseline HbA1c of 6.5% showed a 20% lower risk of CHD and a 16% lower risk of CVD, than a group with a mean HbA1c of 7.5%. These large observational studies on patients with diabetes in everyday clinical practice show a slow improvement in glycaemic control and risk factors in type 1 diabetes. Higher HbA1c level was found to be independently associated with increased risk of CHD and CVD, emphasizing the role of HbA1c as a strong independent risk factor in type 1 diabetes. In type 2 diabetes, increasing risks of CHD and CVD were seen in patients with higher HbA1c levels, while no risk increase was seen in those with low HbA1c levels. HbA1c levels lower than 7% were associated with a lower risk of CVD, providing support for current treatment guidelines. Higher BMI, overweight and obesity independently increased the risk of CHD and CVD in patients with type 2 diabetes, providing additional evidence that overweight and obesity should be counteracted in type 2 diabetes.

Methods: Observational study of 13,477 females and males aged 30-75years, with baseline HbA1c 41-67mmol/mol, systolic blood pressure 122-154mmHg and ratio non-HDL:HDL 1.7-4.1, followed for mean 6.5years until 2012. Four groups were created: a reference group (n=6757) with increasing final versus baseline HbA1c, systolic blood pressure and non-HDL:HDL cholesterol during the study period, and three groups with decreasing HbA1c (n=1925), HbA1c and systolic blood pressure (n=2050) or HbA1c and systolic blood pressure and non-HDL:HDL (n=2745). Results: Relative risk reduction for fatal/nonfatal cardiovascular disease was 35% with decrease in HbA1c only (mean 6 to final 49mmol/mol), 56% with decrease in HbA1c and systolic blood pressure (mean 12 to final 128mmHg) and 75% with combined decreases in HbA1c, systolic blood pressure and non-HDL:HDL (mean 0.8 to final 2.1), all p<0.001 adjusting for clinical characteristics, other risk factors, treatments and previous cardiovascular disease. Similar risk reductions were found for fatal/nonfatal coronary heart disease, fatal cardiovascular disease, all-cause mortality and also in a subgroup of 3038 patients with albuminuria. Conclusion: Considerable risk reductions for cardiovascular disease and mortality were seen with combined long-term risk factor improvement.

- OBJECTIVE: This study was designed to investigate the clinical characteristics of a large type 1 diabetic population and to evaluate the degree of fulfillment of recently updated treatment goals. RESEARCH DESIGN AND METHODS: The Swedish National Diabetes Register was initiated in 1996 as a tool for quality assurance in diabetes care. A1C levels, treatment, and risk factors were analyzed in two cross-sectional samples of 9,424 patients in 1997 and 13,612 patients in 2004 and in a smaller longitudinal sample from 1997 to 2004. RESULTS: Mean A1C decreased from 8.2 +/- 1.3% in 1997 to 8.0 +/- 1.2% in 2004 (P < 0.001). The proportion of patients reaching A1C <7.0% increased from 17.4 to 21.2% in 2004. A slow but significant improvement in blood pressure levels was seen, but only 61.3% reached the blood pressure goal of <130/80 mmHg in 2004. Lipid control improved, and the use of lipid-lowering drugs increased. Among patients treated with lipid-lowering agents, 38% reached the goal of total cholesterol <4.5 mmol/l, and 48% reached the goal of LDL cholesterol <2.5 mmol/l. Successful long-term glycemic and blood pressure control were both independently predicted by low BMI and the absence of microalbuminuria in 1997. CONCLUSIONS: In this large cohort of type 1 diabetic patients, there was a slow improvement in glycemic and risk factor control from 1997 to 2004, although the gap between the clinical results and current Swedish and American treatment goals is still unsatisfactory. It is crucial that additional measures be taken to improve risk factor control in type 1 diabetic patients.

- Background: In effective diabetes management, it is important that providers and health care systems prioritize the delivery of patient-centered care and that they are respectful of and responsive to individual patient preferences and barriers. Objective: The objective of the study was to conduct focus group interviews to capture patients' and health care professionals' perceptions and attitudes regarding digital technology and to explore how the digital Diabetes Questionnaire can be used to support patient participation in diabetes care, as a basis for an implementation study. Methods: A qualitative study was conducted with six focus group discussions with diabetes specialist nurses and medical doctors (n=29) and four focus group discussions with individuals with diabetes (n=23). A semistructured focus group interview guide was developed, including probing questions. The data were transcribed verbatim, and qualitative content analysis was performed using an inductive approach. Results: Two main categories were revealed by the qualitative analysis: perceptions of digital technology and the digital questionnaire in diabetes management and care and perceptions of participation in diabetes care. An overarching theme that emerged from the focus group interviews was patients' and professionals' involvement in diabetes care using digital tools. Conclusions: The analysis identified important factors to consider when introducing the digital Diabetes Questionnaire in clinical use. Both professionals and patients need support and training in the practical implementation of the digital questionnaire, as well as the opportunity to provide feedback on the questionnaire answers.

- BackgroundThe Swedish National Diabetes Register (NDR) initiated registration of the FreeStyle Libre (R) system and other continuous glucose monitoring (CGM) systems in June 2016. We investigated change in HbA1c for people with type 2 diabetes (T2DM) using FreeStyle Libre in Sweden.MethodsWe included adults with T2DM, registered in the NDR after January 1, 2014, and an index date for first use of FreeStyle Libre of June 2016 or later. Methodology was a before/after comparison of HbA1c within 6 months before the index date versus HbA1c around 6 and 12 months after the index date.Results711 adults with T2DM using FreeStyle Libre had HbA1c measurements within the study period. Mean HbA1c was significantly reduced at 6 months (-0.50%-unit) and at 12 months (-0.52%-unit) in this group. Degree of change was negatively correlated to baseline HbA1c. Reductions in HbA1c were observed in incident users of FreeStyle Libre with T2DM who were truly naive to CGM or had unknown prior experience of CGM, and aged 25-74 years.ConclusionsThis real-world study on the Swedish NDR shows that people with T2DM using FreeStyle Libre system for 6 and 12 months significantly reduced their HbA1c.

- AIMS/HYPOTHESIS: The aim of this study of type 2 diabetic patients in the Swedish National Diabetes Register was to study the associations of BMI, overweight (BMI 25-29.9 kg/m(2)) and obesity (BMI >or= 30 kg/m(2)) with cardiovascular disease in type 2 diabetes, as these associations have not previously been clarified. METHODS: Patients aged 30-74 years with no previous CHD or stroke (N = 13,087) were followed for a mean of 5.6 years until 2003 for fatal or non-fatal CHD, stroke, cardiovascular disease (CHD or stroke) and total mortality. In total, 1,922 cardiovascular-disease events occurred, based on 64,864 person-years. RESULTS: The relative risks of CHD, stroke, cardiovascular disease and total mortality for a 5 unit increase in BMI at baseline were 15%, 11%, 13% and 27%, respectively, using Cox regression analysis, after adjusting for age, sex, diabetes duration, hypoglycaemic treatment and smoking (model 1), and were 9%, 4% (not significant), 7% and 20%, respectively, when adjusting also for HbA(1c), blood pressure, antihypertensive drugs, lipid-reducing drugs and microalbuminuria (model 2). Adjusted hazard ratios (model 1) for CHD, cardiovascular disease and total mortality with overweight were 1.27 (95% CI 1.09-1.48), 1.24 (1.09-1.41) and 1.16 (0.94-1.45), respectively, and 1.49 (1.27-1.76), 1.44 (1.26-1.64) and 1.71 (1.36-2.14) with obesity, as compared with normal weight. Significant hazard ratios were attenuated when adjusted according to model 2. For a 1 unit increase in BMI during follow-up, the relative risk of CHD (model 2) was 1.13 (1.04-1.23; p = 0.005). CONCLUSIONS/INTERPRETATION: Both overweight and obesity independently increased the risk of CHD and cardiovascular disease in patients with type 2 diabetes. The CHD risk was higher with increasing BMI than with stable or decreasing BMI during the study.
