Metric evidence of the success of Tableau
Increased engagement with data: Previously, the organization had no ability to subscribe to reports. Now, there are 1,157 registered Tableau Server users, with 469 visualizations subscribed to on a daily, weekly, or monthly basis, across users from the board to the ward. More than 600 visualizations are being viewed on a daily basis, in addition to the 469 subscribed visualizations.
Improved data access: Visualizations are now available to all registered Tableau users, previously these would have been shared manually via email to a small number of users. For example, daily operational reports were previously emailed to a pre-defined list of 25 individuals, these are now viewed on a daily basis by more than 100 individuals—an increase of 400%.
Increased timeliness of data: Manual reports used to be available only five days a week and were updated by 11 a.m. Now they are available seven days a week and are updated at 5 a.m. every morning. This ensures the latest data is automatically available to Southern Health. For example, emergency admissions for all patients within Hampshire are now visualized through Tableau, processing more than 130,000 unplanned clinical interactions with patients.
Efficiency saving: Previous manual processes are now automated through daily Tableau extracts and visualizations. For example one daily report now available through Tableau is saving 45 minutes per day. In total, it is estimated the Information Team is achieving efficiency savings exceeding five working days per calendar month, a figure that is increasing week on week as new functionality is released.
After 12 months of using Tableau, the Information Team is expected to achieve efficiency savings of over 15 working days per calendar month. Within 24 months, this figure is expected to increase to an efficiency saving of over 30 working days per calendar month. This efficiency savings is used to transform the role of analysts to support cultural improvements in the use of data across the organization and complete more ad hoc analysis to facilitate service improvement and redesign.
Improvements to data quality: Tableau has resulted in increased visibility of data and performance and as such has facilitated improvements to data quality across a number of key performance metrics. For example, one mental health metric has experienced an improvement in data quality of over 23% with performance and data quality being sustained at between 99% and 100% for the last eight weeks.
