The document discusses pointillist charts that visualize patient flow and length of stay data for emergency departments. It describes the current charts, which are based on local Scottish data, and plans to produce standardized charts using national Irish health data. The charts cover metrics like length of stay by arrival time, flow group, and breach reason. There are aims to expand the charts to include additional breakdowns of the data and integrate them into a system for monitoring hospital performance.

1. Pointillist Charts: A&E
• Currently based on local data supplied by selected sites
(maintained by Scottish Government analysts)
• 8 charts covering Length of Stay by Arrival Time, Flow
Group, Breach Reason, Admission type
• Cumulative LOS and Hourly Occupancy

2. System Watch Development A&E:
Pointillist Charts
• Produce once, for all NHS Boards and all sites
• ISD have produced charts on Length of Stay by Arrival
Time, Flow Group and Breach Reason (Published in secure
area with MMI A&E data)
• Time Lag currently based on monthly National Data split by
week
• Currently moving to weekly submissions into National Data
(12 NHS Boards by end of October)
• Further development of tool (e.g. split by age, condition,
new time points)
• Include suite of charts into System Watch
