    Applying the Guided Self‐Determination Counselling Method in Primary Healthcare Among People at Risk of Developing Type 2 Diabetes: A Qualitative Study

    by Beate‐Christin Hope Kolltveit, Elín Arnardóttir, Bjørg Frøysland Oftedal, Árún K. Sigurðardóttir

    Aim: To explore how nurses experienced using the Guided Self‐Determination ( GSD ) counselling method in primary healthcare for the follow‐up of patients at risk of developing type 2 diabetes. Design: This study had a qualitative design. Methods: We used individual interviews with nurses in Norway ( n = 5) and Iceland ( n = 6) to collect data. The nurses had prior to this qualitative study participated in a randomised controlled trial, by applying the GSD counselling method in primary healthcare. The data was analysed by using qualitative content analysis. Results: The findings in this study resulted in the identification of three categories: (1) Promoting change in patient awareness and motivation, (2) Facilitation of health behaviour change, and (3) Challenges in applying the GSD method in patient consultations. The counselling method assisted the nurses to approach patients in a different way and to ask questions that stimulated personal reflection and increased the patients´ health awareness. Patient or Public Contribution: Patient representatives contributed in discussing the relevance of the study objectives and justification for undertaking the research, and in the development of adequate written patient information for the study.

    “Outcomes of treatment for people with type 2 diabetes within two nurse-led clinics in primary care in Iceland”

    by Matthildur Birgisdóttir, Hafdís Skúladóttir, Árún K. Sigurðardóttir

    As the prevalence of type 2 diabetes increases in Iceland, more nurse-led diabetes clinics have been established in primary health. This study aimed to evaluate treatment outcomes in patients with type 2 diabetes at two rural nurse-led diabetes clinics and compare these outcomes with guidelines. A retrospective cohort study was conducted in primary care settings in Northern Iceland using secondary data from medical recording systems. The sample (n = 88) included patients with two glycated haemoglobin (HbA1c) measurements taken at least 6 months apart (Time 1 and 2). Between Time 1 and 2, HbA1c levels (p = 0.049), body mass index (p = 0.013), and systolic blood pressure (p = 0.040) decreased. At time 2, approximately 70% of patients reached clinical goals for HbA1c levels, 33% for body mass index, 56% for systolic blood pressure, and 49% for diastolic blood pressure. This finding is consistent with those of other European studies in diabetes care. Assessing healthcare outcomes is beneficial for small rural clinics, where work is often conducted in isolation. This programme evaluation study conducted in two nurse-led clinics in Iceland demonstrated improved diabetes outcomes with care aligned with clinical guidelines and provided a baseline for measuring future outcomes.

    Prediabetes and cardiovascular risk factors: the effectiveness of a guided self-determination counselling approach in primary health care, a randomized controlled trial

    by Elín Arnardóttir, Árún K. Sigurdardóttir, Timothy Skinner, Marit Graue, Beate-Cristin Hope Kolltveit

    Identify individuals who are at risk of Type 2 diabetes, who also are at a greater risk of developing cardiovascular disease is important. The rapid worldwide increase in diabetes prevalence call for Primary Health Care to find feasible prevention strategies, to reduce patient risk factors and promote lifestyle changes. Aim of this randomized controlled trial was to investigate how a nurse-lead Guided Self-Determination counselling approach can assist people at risk of type 2 diabetes to lower their coronary heart disease risk. In this randomized controlled study, 81 people at risk of developing type 2 diabetes were assigned into an intervention group (n = 39) receiving Guided Self-Determination counselling from Primary Health Care nurses over three months and a control group (n = 42) that received a diet leaflet only. Measurements included the Finnish Diabetes Risk Score questionnaire and biological measurements of Hemoglobin A1c protein, Body Mass Index, fasting blood glucose, Blood pressure, Cholesterol, High-density lipoprotein, and triglycerides, at baseline (time1), 6 (time2) and 9 months (time 3). A total of 56 participants, equal number in intervention and control groups, completed all measurements. A significant difference between the intervention and control groups, in coronary heart disease risk was not found at 6 nor 9-months. However, within-group data demonstrated that 55.4% of the participants had lower coronary heart disease risk in the next ten years at the 9-month measurement. Indicating an overall 18% relative risk reduction of coronary heart disease risk by participating in the trial, with the number needed to treat for one to lower their risk to be nine. Within the intervention group a significant difference was found between time 1 and 3 in lower body mass index (p = 0.046), hemoglobin A1c level (p = 0.018) and diastolic blood pressure (p = 0.03). Although unable to show significant group differences in change of coronary heart disease risk by this 12-weeks intervention, the process of regular measurements and the guided self-determination counselling seem to be beneficial for within-group measures and the overall reduction of coronary heart disease risk factors. This study is a part of the registered study ‘Effectiveness of Nurse-coordinated Follow-Up Programme in Primary Care for People at Risk of T2DM’ at www.ClinicalTrials.gov (NCT04688359) (accessed on 30 December 2020).

    When great responsibility comes with limited options: experiences and needs of older community-dwelling adults regarding accessing, understanding, appraising and using health-related information

    by Sonja Stelly Gustafsdottir, Lena Mårtensson, Arun K. Sigurdardottir, Solveig A. Arnadottir

    In previous research, older adults have been associated with reduced levels of health literacy (HL) influenced by a range of contextual factors. To optimise HL, it is essential to better understand the interactions between the ageing process and both personal and environmental factors as perceived by older adults. This study aimed to explore the experiences and needs of older community-dwelling adults when accessing, understanding, appraising and using health-related information. An explorative, qualitative design was used within the social constructivism framework. Semi-structured individual interviews were conducted with 20 adults aged 70–96 living at home in three areas in Northern Iceland. The transcribed interviews were constructed into categories and subcategories using qualitative content analysis. Findings. Four categories emerged. “Expectations for responsibility” describes the experience that individuals are responsible for taking care of their health, including accessing, understanding, appraising and using information and services, showing initiative and keeping needed communications active. “A gap between expectancy and ability/context” includes experiences while taking responsibility for expectations not aligning with skills/situations, creating information gaps. “Finding one’s own ways” comprises various adapted ways to access, understand, and use information and services. “Bridging the gap” describes experiences of needing shared responsibility and more manageable options to enable reasoned health-related decisions and navigation in the healthcare system. The participants valued and took full responsibility for accessing, understanding, appraising and using information and services as part of a social norm; however, they experience information gaps. They request shared responsibility by being provided with fundamental health-related information as a vital step in making reasoned health-related decisions and navigating the healthcare system. They also request more inclusive and accessible service opportunities to bridge the gaps and facilitate HL. It is necessary to critically address, at a systematic level, the conflict between expected individual responsibility and the existence of options to act upon this responsibility. In matters of health, health services and HL, the need to analyse and confront structural disadvantages experienced by older adults is highlighted.

    Can Waist-to-Height Ratio and Health Literacy Be Used in Primary Care for Prioritizing Further Assessment of People at T2DM Risk?

    by Elín Arnardóttir, Árún K. Sigurðardóttir, Marit Graue, Beate-Christin Hope Kolltveit, Timothy Skinner

    Background: To identify people at risk of type 2 diabetes. Primary health care needs efficient and noninvasive screening tools to detect individuals in need of follow-up to promote health and well-being. Previous research has shown people with lower levels of health literacy and/or well-being scores are vulnerable but may benefit from intervention and follow-up care. Aims: This cross-sectional study, aimed to identify people at risk for type 2 diabetes by comparing the Finnish Diabetes Risk instrument with the waist-to-height ratio. Further, the difference was examined in health literacy and well-being scale scores in the countryside versus town areas, respectively. Results: In total, 220, aged 18–75 years, participated. Thereof, 13.2% displayed biomarkers at prediabetes level of HbA1c (39–47 mmol/mol); none had undiagnosed diabetes. Of the participants, 73% were overweight or obese. Waist-to-height ratio demonstrated 93.1% of the prediabetes group at moderate to high health risk and 64.4% of the normal group, with an area under the curve of 0.759, sensitivity of 93.3%, and specificity of 63.1%. Residency did not influence prediabetes prevalence, health literacy, or well-being. Conclusion: Waist-to-height ratio and the Finnish Diabetes Risk instrument may be suitable for identifying who need further tests and follow-up care for health promotion in primary care.

    Using HbA1c measurements and the Finnish Diabetes Risk Score to identify undiagnosed individuals and those at risk of diabetes in primary care

    by Elín Arnardóttir, Árún K. Sigurðardóttir, Marit Graue, Beate-Christin Hope Kolltveit, Timothy Skinner

    Background: Prevalence of prediabetes and type 2 diabetes mellitus (T2DM) is increasing worldwide. The objective of this study was to determine the proportion of people in Northern Iceland with prediabetes, at risk of developing T2DM or with manifest undiagnosed T2DM, as this information is lacking in Iceland. Methods: A cross-sectional study. Clients of the three largest primary health care centres in the Health Care Institution of North Iceland (HSN) were invited to participate if fulfilling the following inclusion criteria: a) aged between 18 and 75 years, b) not diagnosed with diabetes, c) speaking and understanding Icelandic or English fluently and d) living in the included service area. Data collection took place via face-to-face interviews between 1 March 2020 and 15 May 2021. Participation included answering the Finnish Diabetes Risk Score (FINDRISC), measuring the HbA1c levels and background information. Results: Of the 220 participants, 65.9% were women. The mean age was 52.1 years (SD ± 14.1) and FINDRISC scores were as follows: 47.3% scored ≤8 points, 37.2% scored between 9 and 14 points, and 15.5% scored between 15 and 26 points. The mean HbA1c levels in mmol/mol, were 35.5 (SD ± 3.9) for men and 34.4 (SD ± 3.4) for women, ranging from 24 to 47. Body mass index ≥30 kg/m2 was found in 32% of men and 35.9% of women. Prevalence of prediabetes in this cohort was 13.2%. None of the participants had undiagnosed T2DM. Best sensitivity and specificity for finding prediabetes was by using cut-off points of ≥11 on FINDRISC, which gave a ROC curve of 0.814. Conclusions: The FINDRISC is a non-invasive and easily applied screening instrument for prediabetes. Used in advance of other more expensive and invasive testing, it can enable earlier intervention by assisting decision making, health promotion actions and prevention of the disease burden within primary health care. Trial registration: This study is a pre-phase of the registered study “Effectiveness of Nurse-coordinated Follow up Program in Primary Care for People at risk of T2DM” at www.ClinicalTrials.gov (NCT01688359). Registered 30 December 2020.

    Basic mobility, accidental falls, and lifetime physical activity among rural and urban community-dwelling older adults: a population-based study in Northern Iceland

    by Solveig A Arnadottir, Lara Einarsdottir, Arun K Sigurdardottir

    The objective of this research was to investigate late-life physical functioning and lifetime history of physical activity (PA) among older adults in rural and urban Arctic communities. Data was collected in a cross-sectional, population-based study among 65 to 92-year-old community-dwelling Icelanders (N = 175, 41% ≥75-year-old, 43% women, 40% rural). Late-life physical functioning was operationalised as: basic mobility (Timed Up and Go in seconds, TUG); fall risk (TUG≥12 sec); a fall (≥1 fall/year); and recurrent falls (≥2 falls/year). PA history was based on a self-assessment. Compared to urban participants, rural participants were more likely to have fallen recently, be at fall risk, and describe more PA history. Among urban participants, no fall in the past year was independently associated with more PA in middle adulthood; and worse basic mobility and late-life fall risk were independently associated with being in the ≥75-year-old group. Among rural participants, recurrent falls were independently associated with being a man; and better basic mobility was independently associated with more PA in late adulthood. To conclude, this evidence supports an important association between better late-life physical functioning and more mid- and late-life PA and encourages further research to understand high fall risk among older men in Arctic rural areas.

    Making Europe health literate: including older adults in sparsely populated Arctic areas

    by Sonja S. Gustafsdottir, Arun K. Sigurdardottir, Lena Mårtensson, Solveig A. Arnadottir

    Background: Older people have been identified as having lower health literacy (HL) than the general population average. Living in sparsely populated Arctic regions involves unique health challenges that may influence HL. The research aim was to explore the level of HL, its problematic dimensions, and its association with the selection of contextual factors among older adults living in sparsely populated areas in Northern Iceland.Method: This was a cross-sectional study based on a stratified random sample from the national register of one urban town and two rural areas. The study included 175 participants (57.9% participation rate) who were community-dwelling (40% rural) and aged 65–92 years (M74.2 ±SD6.3), 43% of whom were women. Data were collected in 2017-2018 via face-to-face interviews, which included the standardised European Health Literacy Survey Questionnaire-short version (HLS-EU-Q16) with a score range from 0 to 16 (low-high HL).Results: The level of HL ranged from 6–16 (M13.25,SD± 2.41) with 65% having sufficient HL (score 13–16), 31.3% problematic HL (score 9–12) and 3.7% inadequate HL (score 0–8). Most problematic dimension of HL was within the domains of disease prevention and health promotion related to information in the media. Univariate linear regression revealed that better HL was associated with more education (p=0.001), more resiliency (p=0.001), driving a car (p=0.006), good access to health care- (p=0.005) and medical service (p=0.027), younger age (p=0.005), adequate income (p=0.044) and less depression(p=0.006). Multivariable analysis showed that more education (p=0.014) and driving a car (p=0.017) were independent predictors of better HL.Conclusion: Difficulties in HL concern information in the media. HL was strongly associated with education and driving a car however, not with urban-rural residency. Mobility and access should be considered for improving HL of older people.
