Patient decision aids

Patient decision aids help to supplement counselling by physicians on treatment options and outcomes, so that patients can make specific, informed decisions about their care. Holbrook and coauthors report on their study of whether patients' treatment choices are influenced by certain features of decision aids (their format and their graphic presentation of data on treatment benefits and harms) and the names of the treatments themselves. In a related commentary, O'Connor emphasizes how important decision aids are in helping patients navigate the “grey zone” of medical decision-making, where the best choice differs depending on how patients weigh the benefits and risks.
Tighter anticoagulation control decreases adverse events
In a meta-analysis of studies involving more than 71 000 people taking anticoagulants orally, Oake and colleagues found that almost half of all hemorrhages and thromboemboli occurred when patients' international normalized ratios were over or under their therapeutic range. The investigators suggest that improved anticoagulation control could decrease the likelihood of such events, and they encourage the evaluation of interventions such as anticoagulation clinics and patient self-management for implementation.
