Drug interactions and multiple drug administration.

Effects of multiple drug administration on adverse drug reactions were studied in 10,518 patients hospitalized on a general medical service during a five-year period. Nine index drug groups, including analgesic, antacid, antiarrhythmic, antimicrobic, anticoagulant, antihypertensive, anti-inflammatory, diuretic, and sedative-tranquilizer drugs, were selected for study. The average number of adverse drug reactions for the anticoagulant and antihypertensive drug groups was higher (p less than 0.05) than for all other drug groups when classified by the number of drugs being taken concurrently (i.e., 0 to 5, 6 to 10, etc.). The rate of reaction for anticoagulant and antihypertensive drug groups was higher (p less than 0.001) than the rate for other drug groups studied. These data suggest a higher risk of adverse drug reactions for patients receiving multiple drugs. The increased risk may result from drug interactions.

Pseudomonas bacteremia. Review of 108 cases.

The current circumstances associated with Pseudomonas aeruginosa bacteremia are reviewed in 108 episodes to assess the impact of new antimicrobial drugs on this infection. Since 1961, Pseudomonas bacteremia has apparently become more frequent with proportional increases in middle-aged patients. The respiratory tract has become the major source of infection. Clinical features are not characteristic, but infected patients are almost uniformly severely ill before blood stream invasion occurs. The use of gentamicin, carbenicillin and colistin has not changed the outcome of Pseudomonas bacteremia. Although better than no antimicrobial treatment, these drugs cannot be shown to be superior to any other available antibiotics. A reassessment is needed to evaluate the relationship between the in vitro action and the effectiveness of antibiotics in the treatment of Pseudomonas infection and the use of gentamicin, carbenicillin and colistin in these bacteremias. In view of the poor results with antibiotics, investigation into immunologic prophylaxis and therapy is needed. At the present time, control of the patients' underlying disease contributes most towards assuring survival with Pseudomonas bacteremia.

Adverse drug reactions leading to hospitalization in children.

During a three-year period of prospective epidemiologic surveillance for adverse drug reactions in a pediatric population, 72 (2.0%) of 3,556 medical admissions were the result of adverse drug reactions. Antineoplastic drugs were most frequently cited as causing a reaction leading to admission. Approximately 40% of the reactions were severe, and four reactions contributed to death.

Drug-associated deaths of medical inpatients.

Of 7,423 medical inpatients, 16 (0.22%) died of drug-associated causes. The overall mortality for all medical inpatients was 6.5%. Eleven of the 16 patients who died of drug-associated causes had been terminally ill; the rest had been seriously ill before the fatal drug reaction occurred. Half of the patients had had either hematologic malignant changes or lupus nephritis. Antineoplastic drugs, azathioprine, prednisone, and heparin sodium were the most frequently implicated drugs. In other studies, we have found widely differing incidences of fatal drug reactions, due to a number of different drugs; these disparities are probably related to variations in the types of illnesses amoung different hospital populations and to varying interpretations of the term "drug-associated death." Extrapolation from the available data to a national incidence of drug-associated deaths is not possible. Drug-associated deaths are relatively uncommon and usually occur in the cases of severely or terminally ill patients treated with potentially highly toxic drugs.
