Smartphone todo list application to improve workflow in an intensive care unit: a superiority quasiexperimental study Abstract   Background  Smartphone todo list app was hypothesized to be more efficient than a paperbased list in the management of workflow and to provide additional benefits.    Purpose  To analyze the impact of a mobile taskmanagement application on the workflow of an ICU medical staff.    Methods  Superiority by a margin test, quasiexperimental study comparing the use of a smartphone application versus standard practice regarding tasks management in an academic ICU. Superiority margin was set at 8% based on a pilot study. During two periods of 20 working days each (October 2018 and January 2019), medical staff managed tasks with both methods on a weekly rotation basis. Primary outcome was the proportion of daily tasks completed. Secondary outcomes assessed usersxe2x80x99 satisfaction and the impact of the app in terms of changes in clinical practice.    Results  25 ICU physicians were enrolled. A total of 1983 tasks were recorded. The proportion of completed tasks per day was higher when using the smartphone app (99% 96100 versus 95% 9398 for the standard group, pxe2x80x89xe2x80x890.006), but did not reach the superiority margin. Smartphone application was perceived as positive experience, as participants felt that they forgot fewer tasks (pxe2x80x89xe2x80x890.02), were more aware of their progress on ongoing or remaining tasks (pxe2x80x89xe2x80x890.03) and observed an improvement in communication among the medical staff (pxe2x80x89xe2x80x890.03).    Conclusion  This study failed to demonstrate the superiority of a smartphone app over paperbased lists regarding the proportion of daily tasks completed. However, positive feedback regarding the application was received from the medical staff.

Mobile Apps to Quantify Aspects of Physical Activity: a Systematic Review on its Reliability and Validity The purpose of this study was to systematically review and evaluate the evidence on the accuracy (validity) and consistency (reliability) of mobile apps used to quantify physical activity. Systematic literature searches were conducted in Pubmed, Science Direct, Web of Science, Physiotherapy Evidence Database (PEDro), Academic Search Complete and IEEE Xplore. Studies were included if they reported on the validity andor reliability of a mobile application aiming primarily at measuring physical activity in humans with or without pathology. The reference lists of included articles were also screened for reports not identified through electronic searches. The methodological quality of included studies was assessed by 2 independent reviewers and data extracted by one reviewer and checked for accuracy by a second reviewer. A total of 25 articles were included in this review, of which 18 refer to validity and 7 to both validity and reliability. Mean percentage difference was used as an indicator of validity and varied between 0.1% and 79.3%. Intraclass Correlation Coefficients varied between 0.02 and 0.99 indicating poor to excellent reliability. There is conflicting and insufficient evidence on the validity and reliability, respectively, of apps for measuring physical activity. Nevertheless, velocity and the place where the smartphone is carried seem to have an impact on validity.
