Implementing total quality management in the Spanish health care system.

A Total Quality Management Programme for the Spanish Health Care System was set in motion in 1986. The first phase of the programme covers three areas: (1) information sources, (2) training, (3) Total Quality activities, through a cascade of four coordinated projects. The first one defines a basic nucleus of patient information and established two national standards: (a) a minimum basic data set, (b) the use of an ICD-9-CM Spanish translation for codification of diagnoses and procedures. The second is an open demonstration project implementing these two standards in National Health Service hospitals and carrying out intensive training on ICD-9-CM codifiers. The third project encompasses two pilot studies on case-mix measurements systems and cost analysis framework. Through the fourth project concepts, methods and tools for Total Quality Management are developed, setting up specific working groups on clinical and organizational indicators for hospitals and primary health care.

[Congenital fibrosarcoma. Apropos of 2 cases].

Two cases of congenital fibrosarcoma are presented. Both tumors showed histological features of malignancy, but were successful treated with simple resections. Recurrent tumor does not seem to predispose to metastatic disease. Local excision is the initial treatment of choice for lesions occurring in newborns and infants.

[Localized pulmonary interstitial emphysema. Therapeutic management of 3 cases].

Persistent localized interstitial emphysema (PLIE) is a severe complication of assisted ventilation in the neonatal period. From january 1980 to may 1982, 156 cases of IRDS where treated in our Intensive Care Unit. Three of these patients developed this type of emphysema. The initial management was conservative. In two cases, when high ventilatory pressures, and oxygen concentrations were needed to maintain normal blood gases, lobectomy was performed. In both of them mechanical ventilation could be withdrawn shortly after surgery. The third case was managed with conservative medical therapy, and the patient died. In conclusion, when PLIE is diagnosed and does not resolve with medical therapy, the patient needs increasingly higher oxygen concentrations and ventilatory pressures, or mechanical ventilation can not be withdrawn, lobectomy should be performed as long as the process is well localized.

[Necrotizing enterocolitis and its surgical management. Study of 35 cases].

Thirty five cases of necrotizing enterocolitis, seen in the past five years in this clinic, are reviewed. Twenty four cases were seen up to December 1977 and eleven cases from January to March 1978 due to a neonatal I.C.U. epidemy. The relationship between some of the accepted perinatal pathogenic factors and the development of necrotizing enterocolitis is analyzed. The temporal relationship of the time of diagnosis to the onset of treatment is an important consideration for the prognosis. We propose surgical treatment if after eighteen hours of treatment there is no improvement. A guideline for the early treatment and surgical indications of acute necrotizing enterocolitis, is suggested.

Unusual anomaly of the small intestine with malabsorption.

Malabsorption as a complication of anatomic congenital anomalies of the small bowel is uncommon. In this case, malabsorption syndrome in infancy, with features suggestive of coexisting disaccharide intolerance and blind loop syndrome, was the major clinical presentation of a combined anomaly, consisting of a large saccular dilation of the ileum containing heterotropic gastric mucosa, and an adjacent small intramesentric cyst partially lined by small bowel epithelium. Prompt reversal of metabolic and nutritional abnormalities followed surgical resection.

[Virilizing adrenal carcinoma (author's transl)].

A case of virilizing adrenal carcinoma, diagnosed in the first year of age, is presented. The difficulties of differential diagnosis with congenital adrenal hyperplasia are briefly discressed. There is not evidence of metastasis 15 months after complete surgical excision of the tumor and repeated detreminations of 17-CO and 17-OH have remained within normal limits. Finally some considerations are made regarding diagnosis, prognosis and treatment.

Synchronous assisted circulation.

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.
