[Hyperkalemia with potassium-sparing and potassium-losing diuretics. Results from the Comprehensive Hospital Drug Monitoring Bern (CHDM)].

Of 5047 in-patients in the Division of Internal Medicine, Zieglerspital Bern (regional/teaching hospital), admitted from 1982 to 1985, 2412 were treated with at least one diuretic. The hospital records of these patients were reviewed with regard in particular to serum potassium and creatinine values as well as potassium supplementation. On the basis of this evaluation the patients were assigned to 6 different treatment groups and the relative occurrence rate of hyperkalemia probably related to drug treatment was determined.
