Clinical decision making: from theory to practice. The individual vs society. Resolving the conflict

Eddy argues for reform of the American health care system. In seeking health coverage, he explains, there are two positions: the first, that of society, seeks to allocate services efficiently; the second, that of the patient, seeks to optimize individual patients' care. Using his illustration of breast cancer coverage from a previous JAMA article (1991 Mar 20; 265 (11): 1446+), Eddy contends that a tradition of decision-making from the second position is the root of present health care inefficiencies. Eddy's ideal would be complete information to physicians and patients about service costs, benefits, and financial feasibility, and an agreed-upon standard of fair resource allocation, based on the threshold of a specific measure of benefit per resource. To approach this ideal, he concludes, we must recognize the problem, pursue education about service costs and benefits and people's desires of the system, and identify and review services that presently are inefficiently utilized.     

Health care use among young children in day care. Results in a randomized trial of early intervention

Exposure of young children to group day-care settings increases the risk of illness and may result in higher use of medical care. These observations raise concerns that the use of such settings for early intervention programs for low-birth-weight infants may increase the already high burden of medical care costs incurred by these children and their families. To address the question of medical care use associated with center-based care, we examined the hospital-based and ambulatory care reported for participants of the Infant Health and Development Program. This project is a multisite randomized trial of an early intervention program for preterm low-birth-weight infants with an intervention including 2 years of center-based care. The Intervention group did not differ in hospital-based care and averaged only two more physicians' visits over the 3-year observation period than the comparison group. We conclude that early intervention programs involving high-quality group care are not accompanied by substantial increases in health care use.     

A successful treatment of an intrarenal arteriovenous fistula by percutaneous embolization

A 37-year-old woman patient, known to have poorly controlled arterial hypertension that was diagnosed following a cerebrovascular accident at the age of 15 years, was referred to our outpatient clinic for investigation in 1987. An intrarenal arteriovenous fistula was diagnosed by selective renal angiography. Embolization of the fistula was performed using four 15-mm/5-cm coils, which induced thrombosis and obstructed the fistula. The vascularization of the affected kidney improved immediately. During the following 4 months, the antihypertensive treatment was stopped gradually, and the patient remained normotensive. This is an unusual case of a large intrarenal arteriovenous fistula, whose etiology was not clear, that was successfully treated by percutaneous embolization.     

Cellular, metabolic, and clinical consequences of adipose mass enlargement in obesity.

When adipose tissue enlarges in obesity, as the result of an imbalance between caloric intake and caloric expenditure, many changes occur in the cellular components of the adipose mass. A combination of increased cell size and number underlies the accretion of the adipose mass, however, only a reduction in cell size is possible with weight loss. Several metabolic abnormalities accompany obesity--most important--hyperinsulinemia, hyperlipidemia, insulin resistance, and carbohydrate intolerance. Clinical consequences of obesity include hypertension, venous insufficiency, gallbladder disease, osteoarthritis, pulmonary and cardiovascular insufficiency, diabetes, and atherosclerotic cardiovascular disease, and all are dependent on the severity and duration of the obesity. Once established, obesity is difficult to correct because of the development of many adaptive mechanisms by which obesity defends itself.     

Serious respiratory consequences of detergent ingestions in children

After ingesting or inhaling laundry detergent powder, eight children required hospital admission. The predominant symptoms were stridor, drooling, and respiratory distress. All but one patient underwent endoscopy of the airways and the esophagus, five children were admitted to the intensive care unit, and four children required endotracheal intubation. Laundry detergent ingestions are generally considered to have minor consequences, and there exists a paucity of literature on the subject. Evidence of significant morbidity incurred because of ingestion or inhalation of sodium carbonate-containing laundry detergent powder is presented, together with a review of the existing literature.     

Congenital diaphragmatic defects that present late.

Twenty two patients (age range: 1 month to 11 years) were treated for congenital diaphragmatic defects (excluding hiatus hernia) in the six year period 1983-8. Presenting features were failure to thrive (n = 7), abdominal pain and vomiting (n = 4), chronic respiratory symptoms (n = 3), and inability to wean from ventilatory support (n = 3). The defect was an incidental finding in five patients. Operative repair was performed with no mortality or serious postoperative morbidity. Dramatic improvement occurred in 15 of the 17 symptomatic patients. Awareness of the differential diagnosis should avoid delay in diagnosis or inappropriate treatment. Surgical correction is strongly recommended in all cases.
