[Intermediate coronary care units: rationale, infrastructure, equipment, and referral criteria].

The Spanish Working Group on Coronary Artery Disease of Spanish Society of Cardiology has considered to be necessary the development of this document on the need, structure and organization of Intermediate Cardiac Care Units (ICCU). Acute coronary syndrome registries show that an important percentage of patients receive a suboptimal care, due to an inadequate management of health resources or absence of them. Intermediate cardiac care units arise to solve these challenges and to manage in an efficient way these expensive and limited resources. Their aims are: a) to provide each patient the level of care required; b) to optimize the structural, technical and human resources, and c) to make easier continuous care and care gradient. As a result, ICCU should be established as an essential part of the cardiology department aim to cardiac patients requiring monitoring and medical care superior to those available in a regular cardiac ward but whose risk does not justify the technical and human costs of a Coronary Unit. This document describes the structure (equipment, human resources, management) required to reach the goals previously reported and includes recommendations about indications of admission in a ICCU. These indications include: a) patients with NSTE-ACS with intermediate or high risk but hemodynamically stable, and b) low risk STEAMI or high risk STEAMI stabilized after an initial admission at the Coronary Unit. The admission of some patients undergoing invasive procedures or suffering non-coronary acute cardiac diseases, is also considered.
