Title: Making Digoxin Therapeutic Drug Monitoring More Effective
Abstract: Digoxin is an important drug in the treatment of patients with either congestive heart failure or atrial arrhythmia. Because of its narrow therapeutic range, digoxin serum concentrations are commonly monitored in both inpatients and outpatients. However, with the costs of health care skyrocketing, there is debate whether such therapeutic drug monitoring (TDM) is cost-effective. To reduce the number of samples drawn too soon after a previous dose and in an effort to improve digoxin TDM at this teaching hospital, a new dosing and monitoring policy was initiated. This policy involved uniform digoxin dosing at 5 p.m. (1700 h) for all inpatients and serum drug measurements at 7 a.m. (0700 h) the next day. By coordinating the time of dosing to be greater than 12 h prior to serum digoxin analysis, the number of inappropriate digoxin serum determinations have been reduced. This new protocol has increased the effectiveness of the toxicology laboratory and enhanced the efficiency of the house staff. Other issues concerning digoxin TDM are also addressed. These findings can be generalized to all drugs that are monitored at any hospital and can result in a significant cost savings and decrease the time spent analyzing inappropriate data.
