A prolonged QTc interval on electrocardiography is often used as a surrogate marker for ventricular arrhythmia. Medications that can prolong the QTc interval may increase the risk of cardiac complications, although the exact incidence is unknown. It is reasonable to assume that administration of QTc-prolonging medications to patients with pre-existing QTc prolongation will further increase the risk of cardiac consequences. This study was designed to examine the frequency of prescription of QTc-prolonging medications in such patients and to explore the potential for clinical pharmacists to minimize the associated risks. ⋯ A substantial proportion (26%) of patients for whom QTc-prolonging medications were prescribed had pre-existing prolongation of the QTc interval. Clinical pharmacists may have a role in reducing the risk of subsequent complications.

Evaluation of an alcohol withdrawal protocol and a preprinted order set at a tertiary care hospital.
Alcohol withdrawal protocols involving symptom-triggered administration of benzodiazepine have been established to reduce the duration of treatment and the cumulative benzodiazepine dose (relative to usual care). However, the effects of a protocol combining fixed-schedule and symptom-triggered benzodiazepine dosing are less clear. ⋯ Implementation of an alcohol withdrawal protocol with a combination of fixed-schedule and symptom-triggered benzodiazepine dosing in a medical ward was associated with a shorter duration of benzodiazepine use and a lower incidence of severe complications of alcohol withdrawal.

Supporting preceptors is critical to the expansion of experiential learning opportunities for the pharmacy profession. Informal learning opportunities within communities of practitioners are important for hospital preceptors. However, such communities may be limited by geographic separation of preceptors from peers, faculty members, and supports within the pharmacy services department. ⋯ Computer-mediated conferencing allowed preceptors to learn from and to support each other despite geographic distance. The participants felt that these sessions encouraged them to serve as preceptors regularly. Such encouragement could contribute to the retention of preceptors, which is important to the expansion of experiential learning.
