Coronary care unit usage has expanded rapidly in all high income countries with little attention to effectivity or cost. A study of six randomly chosen Swedish units showed that larger units in teaching hospitals had significantly lower age-adjusted mortality rates, higher proportions of myocardial infarction patients, and greater productivity and efficiency. Comparisons with a study from the United States showed better results in the Swedish hospital units according to all variables measured. Although proof of effectiveness of CCU's is lacking, their continued use is assured. A less than optimal solution is a rational distribution of units based upon epidemiologically determined need, while stressing good organization and efficiency.
