Since we wanted to measure the appropriateness of serum digoxin levels in our institution, with the aim of developing interventions to improve it, we undertook a study with the following goals: (1) to develop explicit criteria that define appropriate indications for measuring digoxin levels in both inpatients and outpatients; (2) to use these criteria to evaluate the proportion of digoxin determinations with an inappropriate indication; (3) to describe the indications for ordering determinations of drug levels; and (4) to determine how often levels with an inappropriate indication generated clinically important results. If you’re on digoxin, take as low a dose as possible, and make sure to routinely check your blood levels.

Digoxin level determinations can be clinically useful in patients receiving digoxin therapy for a variety of reasons, including evaluating compliance and verifying toxicity of the therapy.4-6 While many studies have evaluated the use of digoxin therapeutic drug–monitoring services and sampling for drug monitoring of digoxin, few have evaluated the proportion of digoxin level determinations with appropriate indications.7-10. - Digoxin therapy should be monitored by clinical effect rather than serum levels, unless toxicity is suspected.

English-language studies involving the appropriateness of digoxin level monitoring were identified by reviewing the following Medical Subject Heading (MeSH) key words in MEDLINE from 1966 through 1996: digoxin, clinical laboratory, therapeutic drug monitoring, appropriateness criteria, and consensus conference.4-9,11-14 In addition, the bibliographies of original and review articles were searched by hand and relevant references cross-checked with those identified through the computer search. The final criteria were derived based on input from the expert review. Our experts felt annual monitoring was reasonable, but this issue in particular should be evaluated further.
