Analyzing factors determining vaccination willingness against COVID-19 in Germany 2020.

The study is based on a German single-topic population survey on vaccination willingness against COVID-19 (VWC) by the authors (2020, n = 2014). The single-topic survey allowed us to test several competing explanations for VWC, as discussed in the literature. The VWC in the sample was 67.3%. Logistic regression was used to identify factors affecting VWC. Being at high risk from COVID-19 and having received flu vaccination have a positive impact on VWC. Perceived VWC of friends has a strong positive effect on respondents' VWC. Bivariate relationships of gender, age, and level of education with VWC were no longer significant in a multivariate analysis. Trust in alternative medicine and belief in conspiracy theories have a negative effect on VWC.

[Parents' Willingness to Vaccinate with a COVID-19 Vaccine]. / Impfbereitschaft von Eltern mit einem COVID-19-Vakzin: Die Rolle von Elternschaft und Geschlecht.

BACKGROUND: Parents are faced with a vaccination decision in the context of their own vaccination and that of their children with a COVID-19 vaccine. At present, there is no (complete) vaccination recommendation. RESEARCH QUESTION: The study investigates the willingness to vaccinate of parents of minors and people without children who are minors, in which gender differences in particular are examined. METHODS: The study is based on a random sample (telephone survey, n = 2,014, collected between 12 November and 10 December 2020). The evaluation is primarily based on the sub-sample of people with minors in the household (n = 461). RESULTS: Parents of minors consistently show a lower willingness to be vaccinated with a COVID-19 vaccine than respondents without minors (54.1% vs 71.1%). Fathers show a stronger willingness to be vaccinated than mothers. Furthermore, men are more willing to get their own child vaccinated with a COVID-19 vaccine than are women. CONCLUSIONS: Among parents and especially mothers, a considerable misrepresentation of vaccination risks and frequent beliefs in vaccination conspiracy theories can be observed. Clear and easily understandable information on the effects and side effects of vaccination with a COVID-19 vaccine by relevant institutions and physicians is recommended.

[The first steps after a proximal femoral fracture : Sensor-based mobility exploration in geriatric trauma patients]. / Die ersten Schritte nach einer hüftnahen Fraktur : Sensorbasierte Bewegungsexploration bei geriatrischen Traumapatient/-innen.

BACKGROUND: Sensor-based monitoring allows continuous observations of patient mobilization after proximal femoral fractures. A wrist-worn motion tracker allows long-term observation that is low in interruption and constraints for subjects. OBJECTIVE: Description of steps development after hip fracture surgery on a specialized geriatric trauma ward and beyond. MATERIAL AND METHODS: In the explorative long-term field research study, an applicable motion tracker observed steps per day of 20 patients (80% female, mean age 85.2 years ± 7.86 years) for 10 weeks. Weekly mean values (days 1-7, 8-14 etc.) of steps per day formed the database for descriptive analysis (mean, SD, min, max, median). RESULTS: During observation weeks (ow) a positive development of steps took place. A mean increase factor of 1.285 (±0.351) occurred from ow 1 (M = 353.57 ± 310.15) to ow 10 (M = 2482.07 ± 1374.12). The highest increase by a factor of 1.8 could be reported from ow 2 (M = 556.27 ± 478.11) to ow 3 (M = 1024.86 ± 921.24) as well as from ow 6 (M = 1268.21 ± 880.47) to 7 (M = 2367.14 ± 1680.08). A slight decrease of steps occurred from ow 4 (M = 1208.27 ± 1210.45) to ow 5 (0.99-fold) and from ow 9 (M = 2689.98 ± 2339.71) to 10 (0.92-fold). High ranges and standard deviations in relation to the mean occurred constantly. The presence of several step development groups could be presumed. CONCLUSION: Motion tracker and the variable steps per day can represent the ability to walk within an everyday environment, with a possible underestimation of < 10%. Differences regarding observation lengths and disruptions occurred. Cluster analysis should detect group attributes of different courses of development in subsequent studies.

Comparing Monitoring Results of Two Motion Trackers for Geriatric Patients.

BACKGROUND: Fitbit and Garmin motion tracker devices are highly used in research. The validity and reliability of these devices is proven for healthy adults between 18 and 64. OBJECTIVES: Comparing data output of two devices. METHODS: Observational case study on a test track and in the domestic environment of a 80- year-old female multimorbide geriatric patient. RESULTS: High significant correlation of the devices on the test track [r=.776, p≤.001, Bca-CI-95% (.618;.874), N=33], but significant different in the domestic environment over time (z=4.840, p≤.001). CONCLUSION: The dominant/non-dominant body side and further sources of error may play a role in monitoring steps with these devices.

Exploratory Analysis of Motion Tracking Data in the Rehabilitation Process of Geriatric Trauma Patients.

BACKGROUND: This article is based on an ongoing long-term study, in which customary motion trackers measure steps during rehabilitation of geriatric trauma patients (Med=86 years). OBJECTIVES: Exploring steps after 28 days of measurement. Finding similarities in the data by running cluster analysis and formulating linear regressions models to predict steps through time. METHODS: Two types of motion trackers (FitBitAlta HR and Garmin vívofit 3) have been used to measure patients' (N=24) steps after hip fracture in two study groups. Cluster analysis detected three clusters for progress in number of steps that were tested for group differences with ANOVA. Regression analysis tested models for individual patients. RESULTS: Three-cluster solutions showed significant differences for the average amount of steps after 5, 14, 21 and 28 days. Regression models could predict 71 % of the individual patients' progress in study group 2. CONCLUSION: The long-term study will provide more data in the future to examine the three-cluster solution and to find out in what stage of rehabilitation the measurement of the steps could be used to predict individual rehabilitation.

How to Measure Physical Motion and the Impact of Individualized Feedback in the Field of Rehabilitation of Geriatric Trauma Patients.

BACKGROUND: This preparatory study accelerates an implementation of individualized monitoring and feedback of physical motion using conventional motion trackers in the rehabilitation process of geriatric trauma patients. Regaining mobility is accompanied with improved quality of life in persons of very advanced age recovering from fragility fractures. OBJECTIVES: Quantitative survey of regaining physical mobility provides recommendations for action on how to use motion trackers effectively in a clinical geriatric setting. METHODS: Method mix of quantitative and qualitative interdisciplinary and mutual complementary research approaches (sociology, health research, philosophy/ethics, medical informatics, nursing science, gerontology and physical therapy). While validating motion tracker use in geriatric traumatology preliminary data are used to develop a target group oriented motion feedback. In addition measurement accuracy of a questionnaire about quality of life of multimorbid geriatric patients (FLQM) is tested. CONCLUSION: Implementing a new technology in a complex clinical setting needs to be based on a strong theoretical background but will not succeed without careful field testing.
