Predicting Hospital Activity (System Watch)

System Watch is a tool used by NHS Boards and hospitals to monitor and predict numbers of emergency and elective admissions and the number of beds occupied at a national, NHS Board and hospital level. It has been developed to assist with service planning within NHS Scotland. The Scottish Government are provided with information from System Watch to monitor activity across NHS Scotland. This is particularly valuable over the winter period when the weather and public holidays can affect demand on the health service.

Data is received weekly from NHS boards, Health Protection Scotland, Scottish Ambulance Service, NHS 24 and National Records of Scotland. Predictions are available one to six weeks ahead and are based on seasonal and weekly variation and current emergency admission activity. Information is available at national, NHS board and hospital levels.

System Watch Data Mart

The System Watch data mart has been in existence since June 2014. It contains data on inpatient admissions to acute hospitals, derived from weekly submissions made by NHS Boards. Data on the number of deaths is also available, using information provided by National Records of Scotland. The System Watch data mart is one of the multiple data marts contained in the NHS National Services Scotland (NSS) Corporate Data Warehouse. Each data mart represents its own functional area e.g. acute, prescribing, etc.

The data mart holds episodic patient level and stay level information and data is available at national, NHS board and hospital levels. The System Watch data mart is queried using Business Objects and allows users to create adhoc reports.
