Introduction: Goal-setting interviews in randomised controlled trials (RCTs), such as the Bangor Goal-Setting Interview (BGSI), provide personalised, measurable outcomes that are meaningful to participants because they reflect their unique needs. The PRACTIC (PReventing and Approaching Crises for frail community-dwelling patients Through Innovative Care) RCT (2023– 2024) evaluates a biopsychosocial intervention to approach and prevent crises for frail community-dwelling patients. The PRACTIC Goal Setting Interview (PGSI), adapted from the BGSI, focuses on individual goal attainment and readiness to change and was chosen as the primary outcome in the PRACTIC RCT. This study aimed to translate and develop the PGSI, exploring its feasibility, content validity and interrater reliability.

Design and Methods: This study used a convergent mixed-method design; quantitative and qualitative data were collected with equal priority, analysed separately, and compiled for the results and discussion. Two substudies are included: 1) translation and development of the BGSI towards the PGSI and 2) feasibility, content validity and interrater reliability of the PGSI. Substudy 1 comprised field notes from meetings with municipal staff (n=7) across two municipalities. Substudy 2 included data from 28 municipalities participating in the PRACTIC RCT; patient (n=126), next of kin (n=72), and data from focus groups with staff members (n=13) and data collectors (n=5), as well as individual interviews; patients (n=8) and next of kin (n=4).

Results: The PGSI was well received in the home care services and helped strengthen patient involvement. However, there were challenges in using the PGSI, such as time pressure and workload for the staff. After 12 weeks, participants with high motivation showed a significant increase in PGSI compared with those with low motivation (p = 0.010). Analyses also revealed strong positive correlations between participants and staff members assessments of goal attainment at 12 weeks (Spearman’s ρ = 0.87– 0.92, p < 0.001). The results indicate that the PGSI is a valid and reliable tool for improving patient care through structured goal setting and the active involvement of patients and their next of kin.

Conclusion: The PGSI appears to be a useful and feasible tool for goal setting in home care services. The tool strengthens patient engagement and goal attainment with high content validity and interrater reliability.

Abstract

Background: Malnutrition and frailty frequently affect older adults receiving domiciliary care services, increasing their vulnerability to adverse events such as delirium. Despite this, the role of malnutrition as a risk factor for delirium in this population remains under-researched. The aim of this study was to examine the relationship between nutritional status and the development of delirium over a 2-year period among older adults who received domiciliary care services.

Method: In this 2-year prospective cohort study, we included 210 participants aged 65 years or older who received domiciliary care services at least once per week. Nutritional status was assessed using the Mini Nutritional Assessment at the time of inclusion, while delirium was assessed weekly, upon admission to hospital, and upon clinical indication according to DSM-5 criteria. Logistic regression analysis was used to examine the relationship between malnutrition and delirium.

Results: Of the sample, 116 (55.2%) were malnourished/at risk of malnutrition at the time of inclusion. Over a 2-year period, 42.4% developed delirium. The odds ratio for developing delirium was 2.00 (95% CI 1.08-3.72, P = 0.028), for the group with malnutrition/risk of malnutrition, adjusted for covariates.

Conclusion: Malnutrition is an independent risk factor for delirium in older adults receiving domiciliary care services. These findings highlight the importance of regular nutritional assessments and interventions to potentially reduce the risk of delirium in this vulnerable population.

Abstract: 

Background: Immersive technologies such as virtual reality (VR) that has been developed the recent years, are now increasingly accessible and offers new opportunities for VR environments combined with games that may enhance physical activity. However, these games may require adaptation and further customization for use among older users. In this pilot study, we investigate the experiences of older adults using a head-mounted VR exercise game that was developed in close collaboration with end users.

Methods: We included ten community-dwelling older adults aged 65 years and older who undertook six VR exercise sessions across a two-week period, each session lasting 15 min. Descriptive information included age, gender, mobility (Timed Up and Go test, TUG), and gait speed (10 m walk test), and daily steps from ankle-worn accelerometers. Semi-structured individual interviews were conducted, transcribed verbatim and analyzed by use of reflexive thematic analysis.

Results: We included four men and six women, age range from 66 to 77 years, with an average gait speed of 1.4 m/sec and an average TUG-time of 7.6 s. Their average activity levels were close to 4200 steps per day. After the trial period, participants’ experiences were that VR is a new and exciting development. They found VR to be more of a game than exercise, and they suggested integrating more challenging activities, physical movement and social engagement to enhance the exercise part of the game. They did not feel that the game facilitated any more physical activity in their daily lives.

Discussion/conclusion: VR is a promising tool that older adults in this trial enjoyed, but the game was not physically demanding enough for the participants. Future adaptations should include more challenges. Game development should focus on tasks that keep players interested and engaged over longer times, without jeopardizing safety.

Background: Knowledge about how older adults walk is crucial for the effective prevention and treatment of various mobility issues as well as treatment evaluation, but it is currently largely limited to laboratory-based measurements. Although laboratory-based data provide relevant information about what older adults can do under standardized conditions, they do not provide insight into how they actually walk in their daily life, a gap that needs to be addressed urgently.

Objective: The objective of this study was to describe how older adults walk in daily life, in relation to age, sex, and level of physical function, using wearable sensor data from a large sample of older adults with a wide range of age and function from the HUNT4 Trondheim 70+ study.

Methods: The current study is based on 1-week accelerometer data (Axivity AX3) from 1289 older adults (mean age 77.41, SD 6.06 years; age range 70-105 years; n=705, 54.7% women). Physical function was assessed using the Short Physical Performance Battery (SPPB). To investigate the effect of age and SPPB score on gait metrics (daily number of steps, 95th percentile speed, mode speed, 95th percentile cadence, mode cadence, and maximum walking bout [WB] distance) for women and men, univariate gamma regression models with log link were used for each outcome measure, with age and SPPB score in separate models. Sex differences were investigated using Mann-Whitney U tests.

Results: Older adults showed a large variation in how and how much they walked in daily life across age, sex, and physical function, particularly younger participants and those with better physical function. Most gait metrics decreased at an increasing rate with higher age, with men maintaining their levels up to higher ages than women. Poorer physical function led to an exponential or close-to-linear decrease in all gait metrics apart from habitual cadence, which remained stable up to a high age. Women had a lower daily number of steps, gait speed, and maximum distance but higher cadence than men (P<.001 for all). On average, 63% of all WBs lasted <10 seconds, corresponding to a median accumulated time of 99 (IQR 66-128) minutes. For WBs lasting 10 to 30 seconds, 30 to 60 seconds, and >60 seconds, the median accumulated time was 105 (IQR 65-154) minutes, 31 (IQR 18-47) minutes, and 113 (IQR 37-219) minutes, respectively.

Conclusions: Daily-life walking performance was affected more by functional ability than by age itself, except for the highest ages, and differed significantly between sexes. Although most WBs were very short, the total accumulated walking time in WBs shorter than 30 seconds was longer than that in longer WBs. Future research can build upon our findings by considering both the impact of short WBs and relevant group and sex differences when implementing daily-life mobility assessment in both clinical studies and patient follow-up.

Abstract:

Purpose:
Suicide rates are high among older adults, yet research on risk factors associated with suicide in this age group remain largely unexplored. This study aims to examine the relationship between suicide and sociodemographic characteristics among individuals aged 60 and older.

Methods:
We utilized data from Norwegian national registries, identifying individuals aged 60 and older who died by suicide between 2005 and 2019 (n = 2060, 70.7% males), and used a case-control design. To examine the relationships between suicide and sociodemographic factors, we used descriptive analyses and conditional multivariate logistic regression analyses, stratified by sex and age categories.

Results:
Among individuals aged 60 to 69, risk factors for suicide included receiving a disability pension (odds ratio (OR) = 2.79 males, OR = 7.71 females), having mixed income sources (OR = 1.79 males, OR = 3.70 females), living alone (OR = 2.49 males, OR = 2.46 females), and living in urban areas, which was associated with an increased risk for females (OR = 1.85). Among males, living alone was also a significant risk factor for suicide in the 70 to 79 age group (OR = 1.85), and those aged 80 and above (OR = 2.16). Living in rural areas reduced risk for females aged 80 and above (OR = 0.05).

Conclusion:
This first register-based study of suicide in older adults in Norway highlights that living arrangements, urbanization level, and income source are significant risk factors for suicide among older adults. Interventions to improve social connectedness, with a focus on the urban-rural divide, could potentially reduce suicide risk. Sex and age categories should be considered in future research and when implementing preventive measures.

Background: As life expectancy increases, the incidence of age-related chronic health conditions and functional decline rises, increasing the need for institutional long-term care such as nursing homes. In Norway, 84% of nursing home residents have mild cognitive impairment or dementia. This population is characterized by a high burden of neuropsychiatric symptoms (NPS), which contribute to limited physical activity (PA) and a largely sedentary lifestyle. Regular PA is essential for maintaining physical function (PF) and independence, yet nursing home residents spend most of their time being sedentary. The present study aims to explore sensor-based measured PA patterns and investigate how PA is associated with NPS and PF in nursing home residents.

Methods: This cross-sectional study used data from the fourth wave of the population-based Trøndelag Health Study 70-years-and-older cohort (HUNT4 70+), including activity data from a total of 163 nursing home residents. PA was measured using two accelerometers placed on the lower back and thigh. PA patterns were described through the activity types walking, standing, sitting, and lying, activity bouts, and transitions. NPS was assessed using the Nursing Home Version of the Neuropsychiatric Inventory (NPI-NH), and PF using the Short Physical Performance Battery (SPPB). All outcome variables were grouped based on cognitive impairment and dementia severity, set by clinical experts using the DSM-5 diagnostic criteria and the Clinical Dementia Rating (CDR) scale.

Results: Participants’ mean age was 87.8 years, and 62% were female. With a daily average of 17.6 min walking, 1.1 h standing, 9.9 h sitting, and 12.7 h lying, our nursing home residents spent approximately 94% of the day being sedentary. Walking and standing appeared predominantly in bouts under 10 min across cognitive impairment and dementia severity. No association was found between time spent walking, standing, sitting, lying and transitions from sedentary behavior to activity with NPS. Time spent walking, standing, lying and transitions from sedentary behavior to activity was significantly associated with PF.

Conclusions: PA mainly occurred in bouts shorter than 10 min and sitting and lying accounted for most of the daily behavior. No association was detected between time spent in different activities and NPS. Although time spent walking and standing was limited in all groups, it showed an association with PF. This may suggest that even small amounts of PA play a significant role in maintaining or improving physical capabilities in nursing home residents.

ABSTRACT

Objectives:
The study aims to conduct a systematic review of peer-reviewed articles about psychosocial interventions to reduce the caregiver burden in family caregivers of people with dementia to explore the effectiveness and the type of intervention and methodology used.

Methods:
Five databases were searched (AgeLine, CINAHL, MEDLINE, PsycINFO, PubMed) for studies reporting on experimental research of psychosocial interventions for dementia-related caregiver burden. Data quality checks were completed for included papers.

Results:
Forty-three studies were included in the analysis; about half of them (n = 24) were randomized controlled trials. The types of interventions most often used were psychoeducation (n = 21) and multi-component interventions (n = 12). The caregiver burden was after the intervention successfully reduced in about half of the studies (n = 19). Additionally, 10 studies had success in reducing caregiving burden in one of several assessment measures used. The studies using psychoeducation (57%) and multi-component (58%) intervention approaches had the highest success rates.

Conclusion:
Health professionals should be encouraged to implement psychosocial interventions for caregivers of patients with dementia.

Introduction: Frontotemporal symptoms are usually associated with frontotemporal dementia (FTD), but people with all forms of dementia may develop these symptoms as the dementia disease progresses. Knowledge about psychosocial interventions that meet the needs of people with FTD symptoms, and literature on the subject, is hard to find. The aim of the study was to describe current practice as it is experienced by healthcare experts in the clinical field in Norway.

Method: Three focus groups were conducted. Healthcare personnel with clinical experience in care and treatment to people with FTD and other dementia diseases with frontotemporal symptoms were eligible for inclusion. Qualitative directed content analysis with open coding focusing on both manifest and latent content was applied.

Results: Four categories were described: (1) Dilemmas of anosognosia, (2) establishment of a diagnosis, (3) establishment of post-diagnostic support at home, and (4) establishment of care in the nursing home.

Conclusion: People with FTD and other dementias with frontotemporal symptoms need rigid, easy-to-understand, predictable surroundings and healthcare personnel that are clear, friendly, and respectful in their communication. Post-diagnostic support provided in flexible systems ensuring smooth transitions between services and levels of care is required. To ensure quality of care, frontline healthcare staff should be able to recognize FTD symptoms. To achieve this, supervision and training are needed. More research about clinical care interventions and how to derive good nursing practice should be prioritized.

Abstract

Background: Alcohol is a leading risk factor for disease burden. We examined longitudinal trends in sex and age-specific alcohol consumption among middle-aged and older subjects who had participated in the population-based Trøndelag Health Study (HUNT) in Norway since the 1990s.

Methods: This study included 23,151 individuals aged ≥43 years when they participated in the HUNT2 Survey (1995-1997) and who also had participated in the HUNT3 Survey (2006-2008), and/or the HUNT4 Survey (2017-2019). We used self-reported data to examine trends and identify sex- and age-specific differences in abstinence from alcohol, current drinking, risky drinking (≥8 units of alcohol/week), and heavy episodic drinking (≥5 or ≥6 units of alcohol in one sitting at least monthly). Concentrations of the objective alcohol marker phosphatidylethanol (PEth) were available in subsamples from HUNT3 to HUNT4.

Results: The proportion of subjects with self-reported alcohol abstinence and with PEth concentrations <0.03 µmol/l increased from HUNT2 and/or HUNT3 to HUNT4, while heavy episodic drinking and PEth concentrations ≥0.03 µmol/l decreased from HUNT3 to HUNT4 in both sexes in most age groups, and more in men than in women. There was an increase in risky drinking from HUNT2 to HUNT4 in women and men aged 43-64 years in HUNT2. Men were more likely to consume alcohol than women measured with both self-report and with PEth in most age groups. Among those aged ≥65 years in HUNT2 a convergence between the sexes regarding abstinence and heavy episodic drinking was observed which was mostly caused by changes in men.

Conclusion: Drinking patterns among middle-aged and older Norwegians have changed since the 1990s with a trend toward more abstinence and less heavy episodic drinking and PEth concentrations ≥0.03 µmol/l in both women and men with increasing age. There is a trend of more risky drinking with age among both sexes.
