Tallaght Hospital is one of the biggest healthcare facilities in Ireland. With more than 625 beds and almost 3,000 employees, the hospital provides local, regional, supra-regional and national speciality health services to a massively-growing, urbanised area with a predominantly young population. As you can imagine, such a large operation makes for a very complex mail flow. With a very diverse range of documents and correspondence moving between patients, medical teams, GPs, admin staff, suppliers and a vast network of other stakeholders across the wider medical landscape, that equates to a lot of letters going into envelopes. In 2014, Tallaght Hospital embarked on a project aimed at bringing greater efficiency to this massively complex mail flow.
