Digitalistherapie in der ärztlichen Praxis: Untersuchungen über Indikationen und Dosierungskriterien im niedergelassenen Bereich
2008
: Two hundred digitalized patients under nine freely practising physicians were investigated. One hundred and ninety-six patients received digoxin or one of its derivatives. Of these, 50% did not have therapeutic serum glycoside concentrations, 48% were in the mostly subtherapeutic range and 2% were in the potentially toxic range. Signs of glycoside intoxication were not found. A substantiated indication for glycoside therapy was found in the final analysis in 55% of the patients. In 128 patients, the methyldigoxin dose calculated (0.16 +/- 0.030 mg/d) was markedly in excess of that actually prescribed (0.13 +/- 0.050 mg/d; p less than 0.001), so that there were indications of a general underdigitalization. In addition, it was not possible to anchor the restrictive kidney function as a reason for reduction of digoxin dosage in the prescription behavior. In the long run, only 36% of the patients with justified indication and therapeutic serum glycoside concentration as well as (with reservations) the 3% with potentially toxic serum glycoside concentration profited from the glycoside therapy.
