Diabetes Distress and Associations With Demographic and Clinical Variables: A Nationwide Population-Based Registry Study of 10,186 Adults With Type 1 Diabetes in Norway.

OBJECTIVE: To estimate diabetes distress prevalence and associations with demographic and clinical variables among adults with type 1 diabetes in Norway. RESEARCH DESIGN AND METHODS: In this nationwide population-based registry study, the 20-item Problem Areas in Diabetes (PAID-20) questionnaire was sent to 16,255 adults with type 1 diabetes. Linear regression models examined associations of demographic and clinical variables with distress. RESULTS: In total, 10,186 individuals (62.7%) completed the PAID-20, with a mean score of 25.4 (SD 18.4) and 21.7% reporting high distress. Respondents endorsed worrying about the future and complications as the most problematic item (23.0%). Female sex, younger age, non-European origin, primary education only, unemployment, smoking, continuous glucose monitoring use, more symptomatic hypoglycemia, reduced foot sensitivity, treated retinopathy, and higher HbA1c were associated with higher distress. CONCLUSIONS: Diabetes distress is common among adults with type 1 diabetes and associated with clinically relevant factors, underlining that regular care should include efforts to identify and address distress.

High adherence to recommended diabetes follow-up procedures by general practitioners is associated with lower estimated cardiovascular risk.

AIMS: To explore whether the general practitioners' (GPs') performance of recommended processes of care was associated with estimated risk of cardiovascular disease (CVD) and poor glycaemic control in patients with type 2 diabetes. METHODS: A cross-sectional study from Norwegian general practice including 6015 people with type 2 diabetes <75 years old, without CVD and their 275 GPs. The GPs were split into quintiles based on each GP's average performance of six recommended processes of care. The quintiles were the exposure variable in multilevel regression models with 10-year risk of cardiovascular events estimated by NORRISK 2 (total and modifiable fraction) and poor glycaemic control (HbA1c >69 mmol/mol (>8.5%)) as outcome variables. RESULTS: The mean total and modifiable estimated 10-year CVD risk was 12.3% and 3.3%, respectively. Compared with patients of GPs in the highest-performing quintile, patients treated by GPs in the lowest quintile had an adjusted total and modifiable CVD risk that was 1.88 (95% CI 1.17-2.60) and 1.78 (1.14-2.41) percent point higher. This represents a relative mean difference of 16.6% higher total and 74.8% higher modifiable risk among patients of GPs in the lowest compared with the highest quintile. For patients with GPs in the lowest-performing quintile, the adjusted odds of poor glycaemic control was 1.77 (1.27-2.46) times higher than that for patients with a GP in the highest quintile. CONCLUSIONS: We found a pattern of lower CVD risk and better glycaemic control in patients of GPs performing more recommended diabetes processes of care.

Variation between general practitioners in type 2 diabetes processes of care.

AIMS: To explore variation in general practitioners' (GPs') performance of six recommended procedures in type 2 diabetes patients <75 years without cardiovascular disease. METHODS: Cross-sectional study of quality of diabetes care in Norway based on electronic health records from 2014. GPs (clustered in practices) were divided in quintiles based on a composite measure of performance of six processes of care. We fitted a multilevel partial ordinal regression model to identify GP factors associated with being in quintiles with better performance. RESULTS: We identified 6015 type 2 diabetes patients from 275 GPs in 77 practices. The GPs performed on average 63.4% of the procedures; on average 46% in the poorest quintile to 81% in the best quintile with a larger range in individual GPs. After adjustments, use of a structured follow-up form was associated with GPs being in upper three quintiles (OR 12.4 (95% CI 2.37-65.1). Routines for reminders were associated with being in a better quintile (OR 2.6 (1.37-4.92). GPs' age >60 years and heavier workload were associated with poorer performance. CONCLUSION: We found large variations in GPs' performance of processes of care. Factors reflecting structure and workload were strongly associated with performance.

Making Use of Comparable Health Data to Improve Quality of Care and Outcomes in Diabetes: The EUBIROD Review of Diabetes Registries and Data Sources in Europe.

Background: Registries and data sources contain information that can be used on an ongoing basis to improve quality of care and outcomes of people with diabetes. As a specific task of the EU Bridge Health project, we carried out a survey of diabetes-related data sources in Europe. Objectives: We aimed to report on the organization of different sources of diabetes information, including their governance, information infrastructure and dissemination strategies for quality control, service planning, public health, policy and research. Methods: Survey using a structured questionnaire to collect targeted data from a network of collaborating institutions managing registries and data sources in 17 countries in the year 2017. Results: The 18 data sources participating in the study were most frequently academic centres (44.4%), national (72.2%), targeting all types of diabetes (61.1%) covering no more than 10% of the target population (44.4%). Although population-based in over a quarter of cases (27.8%), sources relied predominantly on provider-based datasets (38.5%), fewer using administrative data (16.6%). Data collection was continuous in the majority of cases (61.1%), but 50% could not perform data linkage. Public reports were more frequent (72.2%) as well as quality reports (77.8%), but one third did not provide feedback to policy and only half published ten or more peer reviewed papers during the last 5 years. Conclusions: The heterogeneous implementation of diabetes registries and data sources hampers the comparability of quality and outcomes across Europe. Best practices exist but need to be shared more effectively to accelerate progress and deliver equitable results for people with diabetes.

Availability and analytical quality of hemoglobin A1c point-of-care testing in general practitioners' offices are associated with better glycemic control in type 2 diabetes.

Background It is not clear if point-of-care (POC) testing for hemoglobin A1c (HbA1c) is associated with glycemic control in type 2 diabetes. Methods In this cross-sectional study, we linked general practitioner (GP) data on 22,778 Norwegian type 2 diabetes patients to data from the Norwegian Organization for Quality Improvement of Laboratory Examinations. We used general and generalized linear mixed models to investigate if GP offices' availability (yes/no) and analytical quality of HbA1c POC testing (average yearly "trueness score", 0-4), as well as frequency of participation in HbA1c external quality assurance (EQA) surveys, were associated with patients' HbA1c levels during 2014-2017. Results Twenty-eight out of 393 GP offices (7%) did not perform HbA1c POC testing. After adjusting for confounders, their patients had on average 0.15% higher HbA1c levels (95% confidence interval (0.04-0.27) (1.7 mmol/mol [0.5-2.9]). GP offices participating in one or two yearly HbA1c EQA surveys, rather than the maximum of four, had patients with on average 0.17% higher HbA1c levels (0.06, 0.28) (1.8 mmol/mol [0.6, 3.1]). For each unit increase in the GP offices' HbA1c POC analytical trueness score, the patients' HbA1c levels were lower by 0.04% HbA1c (-0.09, -0.001) (-0.5 mmol/mol [-1.0, -0.01]). Conclusions Novel use of validated patient data in combination with laboratory EQA data showed that patients consulting GPs in offices that perform HbA1c POC testing, participate in HbA1c EQA surveys, and maintain good analytical quality have lower HbA1c levels. Accurate HbA1c POC results, available during consultations, may improve diabetes care.
