Strong Association of Perceived Chronic Stress with Leadership Quality, Work–Privacy Conflict and Quantitative Work Demands Göbel, Julian; Degen, Lukas; Minder, Karen; Rieger, Monika A.; Weltermann, Birgitta M. The health of primary care professionals is crucial for the health of populations. A lower number of general practitioners per 1000 patients correlates with higher patient mortality. Challenging work demands, work–privacy conflict, and poor leadership quality are associated with higher perceived chronic stress and/or burnout in physician populations. However, studies investigating the influence of all three factors in a single quantitative model are lacking. This study analysed the associations between the mentioned parameters and perceived chronic stress among general practice personnel based on baseline data of the cluster-randomized IMPROVEjob study. It comprised 60 German general practices with 366 participants (84 general practice leaders, 28 employed physicians, 254 practice assistants). Perceived chronic stress (TICS-SSCS), leadership quality (LMX-7, FIF), work–privacy conflict (COPSOQ), and quantitative and emotional work demands (COPSOQ) were measured with validated questionnaires. The factors associated with lower perceived chronic stress were identified using a multilevel regression model approach. The model showed a significant association with less work–privacy conflict (p < 0.001, β = 0.31), lower quantitative work demands (p < 0.001, β = 0.28), and good leadership quality (p < 0.001, β = −0.22). Especially transformational leadership with the dimension 'innovation of the leader' was associated with lower perceived chronic stress. The data support the importance of high-quality leadership as a protective factor for perceived chronic stress among general practice personnel, which needs to be considered in future leadership interventions in this setting.

Short physical performance battery

Short physical performance battery Küppers, Lucas; Pfannenstiel, Richard; Bozorgmehr, Arezoo; Jonas, Stephan; Weltermann, Birgitta; Reimer, Lara Marie Background: A standardized fall risk assessment can guide targeted interventions. The widely used short physical performance battery (SPPB) for mobility assessment covers balance, gait speed, and lower limb strength, but is time-consuming and requires trained raters. The newly developed video-based smartphone application called MobiSPPB provides a rater-independent SPPB assessment. This study evaluated the technical validity and reliability of the MobiSPPB app compared to the standard rater-based SPPB. In addition, the ability to detect disease-related movement patterns was investigated.
Methods: Using a standardized experimental setting, 10 healthy participants performed the SPPB with and without movement impairments simulated by an instant aging suit. Two experienced raters rated the SPPB performance, and a smartphone recorded at the same time. The MobiSPPB app analyzed videos via vision-based human motion capture techniques. Spearman's correlations, the intraclass correlation coefficient (ICC), and receiver operating characteristic curves were calculated.
Results: There was a strong correlation between the app and standard SPPB (Spearman's Correlation of 0.869, 95% confidence interval (CI) of 0.79–0.92, p < 0.001). Compared with the standard assessment, the app presented a more significant ICC in the test–retest reliability analysis (0.936, 95% CI of 0.87-0.97, p < 0.001). Detecting disease-related movement patterns achieved high accuracy in capturing severe impairments such as hemiplegia (area under the curve (AUC) 93%). Inconsistencies between the raters indicated that the app provides more objective assessments.
Conclusions: The technical validation of the MobiSPPB app was successful in a standardized experimental setting and requires further testing in clinical practice.

Use of the FallAkte Plus System as an IT Infrastructure for the North Rhine-Westphalian General Practice Research Network

Use of the FallAkte Plus System as an IT Infrastructure for the North Rhine-Westphalian General Practice Research Network Bozorgmehr, Arezoo; Thiem, Simon-Konstantin; Wild, Dorothea; Reinsdorff, Melanie; Vollmar, Horst Christian; Kappernagel, Annika; Schloessler, Kathrin; Weissbach, Sabine; Pentzek, Michael; Dehnen, Dorothea; Drexler, Julia; Mueller, Beate Sigrid; Pilic, Larisa; Lehmann, Lion; Loescher, Susanne; Hohmann, Elena Darinka; Frank, Friederike; Ates, Gülay; Kersten, Susanne; Mortsiefer, Achim; Aretz, Benjamin; Weltermann, Birgitta Background: Primary care research networks can generate important information in the setting where most patients are seen and treated. However, this requires a suitable IT infrastructure (ITI), which the North Rhine-Westphalian general practice research network is looking to implement.
Objective: This mixed methods research study aims to evaluate (study 1) requirements for an ITI and (study 2) the usability of an IT solution already available on the market, the FallAkte Plus (FA+) system for the North Rhine-Westphalian general practice research network, which comprises 8 primary care university institutes in Germany’s largest state.
Methods: In study 1, a survey was conducted among researchers from the institutes to identify the requirements for a suitable ITI. The questionnaire consisted of standardized questions with open-ended responses. In study 2, a mixed method approach combining a think-aloud approach and a quantitative survey was used to evaluate the usability and acceptance of the FA+ system among 3 user groups: researchers, general practitioners, and practice assistants. Respondents were asked to assess the usability with the validated system usability scale and to test a short questionnaire on vaccination management through FA+.
Results: In study 1, five of 8 institutes participated in the requirements survey. A total of 32 user requirements related primarily to study management were identified, including data entry, data storage, and user access management. In study 2, a total of 36 participants (24 researchers and 12 general practitioners or practice assistants) were surveyed in the mixed methods study of an already existing IT solution. The tutorial video and handouts explaining how to use the FA+ system were well received. Researchers, unlike practice personnel, were concerned about data security and data protection regarding the system’s emergency feature, which enables access to all patient data. The median overall system usability scale rating was 60 (IQR 33.0-85.0), whereby practice personnel (median 82, IQR 58.0-94.0) assigned higher ratings than researchers (median 44, IQR 14.0-61.5). Users appreciated the option to integrate data from practices and other health care facilities. However, they voted against the use of the FA+ system due to a lack of support for various study formats.
Conclusions: Usability assessments vary markedly by professional group and role. In its current stage of development, the FA+ system does not fully meet the requirements for a suitable ITI. Improvements in the user interface, performance, interoperability, security, and advanced features are necessary to make it more effective and user-friendly. Collaborating with end users and incorporating their feedback are crucial for the successful development of any practice network research ITI.
