A summary of the work in synchronous assisted circulation undertaken at the Tufts-New England Medical Center Hospitals for the past year is presented.Counterpulsation, introduced in 1958, reduces myocardial oxygen consumption and increases coronary flow. It was applied to seven patients with terminal cardiogenic shock: one patient survived and three showed temporary improvement.The synchronous external assist makes possible control of the blood volume distribution, increases the cardiac output and decreases the pressure work of the left ventricle. The procedure does not require cannulation of the vascular system and is atraumatic.The same concept has been applied to the right ventricle using synchronous respiration.An "in-series" subcutaneously exteriorized prosthetic left ventricle, capable of long-term left ventricular assist, is under development. The device can atrialize the left ventricle. It requires no intracorporeal source of energy.This program offers hope for the development of effective temporary and long-term circulatory-assist procedures.

The profound political changes that followed the Spanish Constitution of 1978 have had a major influence in the healthcare offered to the Spanish population. The healthcare provision once centred in a single government agency, the Instituto Nacional de la Salud (INSALUD), is now being decentralized to the 17 autonomous regions established by the Constitution. Existing Spanish legislation, traditional accountability and established professional roles are determinant factors in defining the boundaries amongst the main stakeholders in the healthcare accreditation issue. Hospital accreditation has been traditionally understood by the central government agency as a way to assure regulated standards for licensing the operations of healthcare facilities. However, recent public concern over the quality of healthcare, health departments' accountability and health professional technical knowledge are now creating the search for a common approach to accreditation in Spain.
