[Malaise and its cost: the cost effectiveness of complementary tests]

A study of 200 patients hospitalized in the Internal Medicine ward for malaise enabled us to specify several clinical features and to estimate the cost of this disorder. Clinical data from our investigation showed that the mean age of patients was 60 +/- 1.7 years, the women were older than the men, and age is an important parameter for orienting examinations which affects the length of hospitalization and increases with it. Among the etiological diagnoses of malaise, the systematic search for orthostatic hypotension is extremely important: it was responsible for 22 of the malaises of which only half were diagnosed in the emergency room. In addition, 12% of our series of malaises were medication-associated. The 200 patients represent 1,300 hospital-days at a total cost of 2,273,000 FF (congruent to US$454,600), and an average cost of 11,660 FF (congruent to US$2330) per malaise, of which 730 FF (congruent to US$145) was paid for complementary examinations. Thus it appears that the "hotel accommodations" part of the bill is the major element. All the complementary examinations ordered during the etiological search do not provide the same information and cost-benefit analysis showed that several simple tests, i.e., ECG, blood-sugar level, blood electropherogram and dosage of toxic substances, led to approximately 75% of the diagnoses; more sophisticated tests, e.g., cerebral computed-tomography scanning, Holter ECG or echocardiography, did not concern more than 25% of the malaises studied.(ABSTRACT TRUNCATED AT 250 WORDS)
