Intravenous metoprolol versus diltiazem for rate control in noncardiac, nonthoracic postoperative atrial fibrillation.

Background: Little guidance exists on effective management of postoperative atrial fibrillation (POAF) following noncardiac, nonthoracic (NCNT) surgery.

Objectives: The purpose of this study was to identify whether a difference exists between intravenous (IV) metoprolol and diltiazem when used to achieve hemodynamically stable rate control in POAF following NCNT surgery.

Methods: This retrospective cohort study examined critically ill adult surgical patients experiencing POAF with rapid ventricular response.

Quality and safety in home and ambulatory settings.

Much of the work in quality and patient safety has been based in hospitals and other acute care settings, yet it has become increasingly apparent that there are errors in delivery of care in other settings, all of which require attention. This article reviews sources of errors in 3 nonacute settings: the home, children's day care, and ambulatory surgery centers. Also described are standards that have been developed to guide practice, as well as specific regulatory agencies that are involved and some of the safeguards that have been instituted in each of the settings to protect against errors.
