Utilisation and outcomes following the introduction of an interventional radiology day unit.
OBJECTIVE
To assess the utilisation of an interventional radiology day unit (RDU), the rates of on-time discharges, the financial performance of the unit, and finally, the patient satisfaction rates.


METHODS
Data regarding the unit utilisation, discharge times, and complications were retrospectively collected for the first 2 years of operation of the unit (1 April 2013 to 1 January 2015). In addition, monitoring the activity going through the RDU and applying a contribution margin to the freed-up beds measured the financial performance. The data were provided by the finance department of the hospital. Satisfaction survey questionnaires were sent randomly by post to 100 patients who had been previously admitted to the RDU.


RESULTS
During the study period, 3019 patients were admitted to the RDU, comprising 1426 during the first year and 1513 during the second. On average, 5.6 patients were discharged from the RDU on every working day during the first year and 7.1 patients during the second (21% increase in the discharge rate). Given the 8-hour working time configuration of the unit, a realistic 80% utilisation rate of the RDU's seven beds could free a total of 1400 inpatient bed days over a full year. The cost of delivering these episodes of care was reduced by approximately 50%. From the financial data, it was estimated that the RDU managed to achieve a total of £393,000 in savings for the Trust for the financial year 2013-2014. The return rate of the patient satisfaction survey was 40%. All patients were satisfied with their overall RDU experience.


CONCLUSIONS
The RDU has brought significant benefits for patients and the Trust without compromises in safety or quality.
