- 2023

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on glycemic control measured as HbA1c in type 1 diabetes (T1D) patients during childhood and especially during adolescence, both in a Swedish and an international context, and relates the glycemic control to the risk of complications in young adults. In studies I and II, the Swedish Pediatric Diabetes Quality Register (SWEDIABKIDS) and the Swedish National Diabetes Register (NDR) were used. More than 4000 young adults with T1D and data on HbA1c in NDR both in 2011 and 2012 as well as data on HbA1c in SWEDIABKIDS were used. The T1D patients with poor glycemic control during their teenage period had a risk for retinopathy several times higher than those with good glycemic control. The risk for micro- and macroalbuminuria was also higher in those with poor glycemic control and was most pronounced in the T1D patients with high HbA1c in both registers. Females had worse glycemic control than males during the teenage period and an increased risk of retinopathy as young adults. In studies III and IV, pediatric diabetes quality register data from, respectively, eight and seven Western high-income countries were collected in the year 2013. Data on about 60 000 T1D patients were analyzed according to mean HbA1c levels in the countries and related to actual age and T1D duration to determine if there were differences in glycemic control between the countries. There were large differences in mean HbA1c between the countries, both when related to age and T1D duration. Despite the differences in mean HbA1c, the increase in mean HbA1c with increasing age and T1D duration was very similar in all countries. The overall picture of these studies is that good glycemic control is very important to avoid complications of T1D as young adults, and it seems particularly important to maintain a good glycemic control during adolescence. Furthermore large differences in glycemic control in T1D patients in Western high-income countries were found. Despite the differences in glycemic control, the pattern of rising HbA1c with increasing age and duration of T1D was very similar in all countries. Females have worse glycemic control than males during their teenage period, both in Sweden and internationally, and they also have more retinopathy as young adults. This thesis shows that it is of the utmost importance to treat T1D patients intensively directly after diagnosis, to treat the young T1D patients intensely and to reduce the rise in HbA1c with increasing age and duration of T1D in order to avoid complications early in life. Diabetes quality registers give the opportunity to compare results and share experiences, both within and between countries, so treatment of T1D can be designed in the best possible way and thereby minimize T1D complications.

- Aims: To evaluate how HbA1c in adolescents with type 1 diabetes affects microvascular complications in young adults. Methods: All individuals registered in the Swedish paediatric diabetes quality registry (SWEDIABKIDS) 13-18 years of age, and as adults registered in the Swedish National Diabetes Registry (NDR) in both the years 2011 and 2012 were included, in total 4250 individuals. Results: Of the individuals with mean HbA1c >78 mmol/mol in SWEDIABKIDS 83.4% had retinopathy, 15.8% had microalbuminuria and 4.9% had macroalbuminuria in NDR. The logistic regression analysis showed that the OR to develop macroalbuminuria as a young adult was significantly higher in the group with mean HbA1c >78 mmol/mol in SWEDIABKIDS (p < 0.05). Among the patients with mean HbA1c above 78 mmol/mol in both registries there was a significantly higher proportion that had retinopathy, microalbuminuria (p < 0.001) and/or macroalbuminuria (p < 0.01) compared to the group with HbA1c below 57 mmol/mol in both registries. Only 6.5% of the persons in this study were over 30 years of age. Conclusions: Paediatric diabetes teams working with teenagers must be aware of the impact of good metabolic control during adolescence, and should intensify the care during this vulnerable period of life to reduce the risk of microvascular complications in young adults.

- OBJECTIVE International studies on childhood type 1 diabetes (T1D) have focused on whole-country mean HbA(1c) levels, thereby concealing potential variations within countries. We aimed to explore the variations in HbA(1c) across and within eight high-income countries to best inform international benchmarking and policy recommendations. RESEARCH DESIGN AND METHODS Data were collected between 2013 and 2014 from 64,666 children with T1D who were amp;lt; 18 years of age across 528 centers in Germany, Austria, England, Wales, U.S., Sweden, Denmark, and Norway. We used fixed-and random-effects models adjusted for age, sex, diabetes duration, and minority status to describe differences between center means and to calculate the proportion of total variation in HbA(1c) levels that is attributable to between-center differences (intraclass correlation [ICC]). We also explored the association between within-center variation and childrens glycemic control. RESULTS Sweden had the lowest mean HbA(1c) (59mmol/mol [7.6%]) and together with Norway and Denmark showed the lowest between-center variations (ICC amp;lt;= 4%). Germany and Austria had the next lowest mean HbA(1c) (61-62 mmol/mol [7.7-7.8%]) but showed the largest center variations (ICC similar to 15%). Centers in England, Wales, and the U.S. showed low-to-moderate variation around high mean values. In pooled analysis, differences between counties remained significant after adjustment for children characteristics and center effects (P value amp;lt; 0.001). Across all countries, children attending centers with more variable glycemic results had higher HbA(1c) levels (5.6mmol/mol [0.5%] per 5mmol/mol [0.5%] increase in center SD of HbA(1c) values of all children attending a specific center). CONCLUSIONS A tsimilar average levels of HbA(1c), countries display different levels of center variation. The distribution of glycemic achievement within countries should be considered in developing informed policies that drive quality improvement.

- Self-directed learning denotes that the individual is in command of what should be learned and why it is important. In this study, guidelines for the design of Web 2.0 systems for supporting diabetic adolescents every day learning needs are examined in light of theories about information behaviour and social learning. A Web 2.0 system was developed to support a community of practice and social learning structures were created to support building of relations between members on several levels in the community. The features of the system included access to participation in the culture of diabetes management practice, entry to information about the community and about what needs to be learned to be a full practitioner or respected member in the community, and free sharing of information, narratives and experience-based knowledge. After integration with the key elements derived from theories of information behaviour, a preliminary design guideline document was formulated.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: The quality of nursing care has a significant impact on the outcomes of care. The specific needs of children requiring hospital care make it essential to monitor and compare data not only on the medically oriented outcome measure but also on nursing care, structure, and process, requiring perspectives from registered nurses (RNs) and nurse managers (NMs). Thus, this project aimed to evaluate the structure and process of nursing quality indicators in pediatric hospital care with questionnaires distributed to RN and NM.Methods: We developed separate questionnaires for NMs and RNs to assess the process and structure of the quality indicators of breastfeeding, management of pain, venous access, medication management, and provision of a child-oriented environment. Nine NMs and 113 RNs from 9 pediatric wards answered the questionnaires.Result: Local guidelines were available for 3 out of the 5 quality indicators: pain management, venous access, and medication management. RNs reported varying levels of adherence to pain management (62%), and venous access management (72%). Satisfaction with the conditions for safe medication management was 90%. Approximately, two-thirds (67%) of RN reported sufficient knowledge regarding the impact of the child-oriented environment and less than half (44%) regarding how to support breastfeeding.Conclusion: Structure and process is a prerequisite for quality of care outcomes. This study discloses areas for quality improvement and offers instruments to compare structure and process in pediatric nursing care to discuss with consumers, managers, staff, and other stakeholders.
