Traditional dedicated coronary care units (CCU) are being decommissioned and cardiology precincts are evolving. These precincts often have cardiac and non-cardiac patients with a diverse array of acuity levels. Critical care trained cardiac nurses are frequently caring for lower acuity patients resulting in a deskilling of this experienced workforce. The aim of this paper was to discuss the implications of restructuring CCUs on nursing workforce and patient outcomes. An integrated literature review was conducted. The following databases were searched for articles published between January 2000 and December 2011: Ovid Medline, CINHAL, EMBASE and Cochrane. Additional studies obtained from the articles searched and policy documents from key professional organisations and government departments were reviewed.
