Objectives: The prevalence of different geriatric syndromes in older home care (HC) recipients is yet to be determined. Dizziness is often regarded as a geriatric syndrome. The natural course of dizziness in older people is still unknown, because of a lack of longitudinal studies. The objective of this study was to investigate the prevalence and persistence of dizziness in HC recipients., Design: Prospective cohort study., Setting: Home care organizations in 6 European countries participating in the EU-funded Identifying best practices for care-dependent elderly by Benchmarking Costs and outcomes of community care (IBenC) project., Participants: 2616 community-dwelling long-term HC recipients aged 65 years or older., Methods: Data were collected at baseline and 6 and 12 months by using the interRAI Home Care instrument (interRAI-HC). Dizziness status was assessed by the number of days people experienced dizziness in the last 3 days (0-3) and later dichotomized for analyses (present or not in the last 3 days). Dizziness persistence was defined as the odds for dizzy people at baseline to also report dizziness at subsequent follow-up moments, compared with people who were not dizzy at baseline. The pattern of dizziness was descriptively analyzed in recipients who completed all measurements. Generalized estimating equations analysis was used to determine the persistence of dizziness symptoms., Results: The prevalence of dizziness of 2616 eligible HC recipients at baseline was 25.1%, ranging from 16.2% (Belgium) to 39.7% (Italy). The majority of dizzy recipients at baseline also experienced dizziness after 6 and 12 months (79.1%). Dizziness persistence was high at 6 months [odds ratio (OR) 57.8, 95% confidence interval (CI) 43.1-77.5] and at 12 months (OR 30.2, 95% CI 22.3-41.1)., Conclusions and Implications: Dizziness in older HC recipients in Europe is common, and dizziness persistence is high. This warrants a more active approach in treating dizziness in older HC recipients., (Copyright © 2019 AMDA – The Society for Post-Acute and Long-Term Care Medicine. Published by Elsevier Inc.

Background: Car driving is a form of passive transportation associated with higher sedentary behaviour, which is associated with morbidity. The decision to drive a car is likely to be influenced by the 'drivability' of the built environment, but there is lack of scientific evidence regarding the relative contribution of environmental characteristics of car driving in Europe, compared to individual characteristics. This study aimed to determine which neighbourhood- and individual-level characteristics were associated with car driving in adults of five urban areas across Europe. Second, the study aimed to determine the percentage of variance in car driving explained by individual- and neighbourhood-level characteristics., Methods: Neighbourhood environment characteristics potentially related to car use were identified from the literature. These characteristics were subsequently assessed using a Google Street View audit and available GIS databases, in 59 administrative residential neighbourhoods in five European urban areas. Car driving (min/week) and individual level characteristics were self-reported by study participants (analytic sample n = 4258). We used linear multilevel regression analyses to assess cross-sectional associations of individual and neighbourhood-level characteristics with weekly minutes of car driving, and assessed explained variance at each level and for the total model., Results: Higher residential density (β:-2.61, 95%CI: - 4.99; -0.22) and higher land-use mix (β:-3.73, 95%CI: - 5.61; -1.86) were significantly associated with fewer weekly minutes of car driving. At the individual level, higher age (β: 1.47, 95%CI: 0.60; 2.33), male sex (β: 43.2, 95%CI:24.7; 61.7), being employed (β:80.1, 95%CI: 53.6; 106.5) and ≥ 3 person household composition (β: 47.4, 95%CI: 20.6; 74.2) were associated with higher weekly minutes of car driving. Individual and neighbourhood characteristics contributed about equally to explained variance in minutes of weekly car driving, with 2 and 3% respectively, but total explained variance remained low., Conclusions: Residential density and land-use mix were neighbourhood characteristics consistently associated with minutes of weekly car driving, besides age, sex, employment and household composition. Although total explained variance was low, both individual- and neighbourhood-level characteristics were similarly important in their associations with car use in five European urban areas. This study suggests that more, higher quality, and longitudinal data are needed to increase our understanding of car use and its effects on determinants of health.

Introduction: Robotic guidance (RG) and computer-assisted navigation (NV) have seen increased adoption in instrumented spine surgery over the last decade. Although there exists some evidence that these techniques increase radiological pedicle screw accuracy compared with conventional freehand (FH) surgery, this may not directly translate to any tangible clinical benefits, especially considering the relatively high inherent costs. As a non-randomised, expertise-based study, the European Robotic Spinal Instrumentation Study aims to create prospective multicentre evidence on the potential comparative clinical benefits of RG, NV and FH in a real-world setting., Methods and Analysis: Patients are allocated in a non-randomised, non-blinded fashion to the RG, NV or FH arms. Adult patients that are to undergo thoracolumbar pedicle screw instrumentation for degenerative pathologies, infections, vertebral tumours or fractures are considered for inclusion. Deformity correction and surgery at more than five levels represent exclusion criteria. Follow-up takes place at 6 weeks, as well as 12 and 24 months. The primary endpoint is defined as the time to revision surgery for a malpositioned or loosened pedicle screw within the first postoperative year. Secondary endpoints include patient-reported back and leg pain, as well as Oswestry Disability Index and EuroQOL 5-dimension questionnaires. Use of analgesic medication and work status are recorded. The primary analysis, conducted on the 12-month data, is carried out according to the intention-to-treat principle. The primary endpoint is analysed using crude and adjusted Cox proportional hazards models. Patient-reported outcomes are analysed using baseline-adjusted linear mixed models. The study is monitored according to a prespecified monitoring plan., Ethics and Dissemination: The study protocol is approved by the appropriate national and local authorities. Written informed consent is obtained from all participants. The final results will be published in an international peer-reviewed journal., Trial Registration Number: Clinical Trials.gov registry NCT03398915; Pre-results, recruiting stage., Competing Interests: Competing interests: VES, GM, PMvK, ET and MLS conceived and designed the study.
