American health care is transitioning to electronic physician ordering. These computerized systems are unique because they allow custom order interfaces. Although these systems provide great benefits, there are also potential pitfalls, as the behavioral sciences have shown that the very format of electronic interfaces can influence decision making. The current research specifically examines how defaults in electronic order templates affect physicians' treatment decisions and medical errors. ⋯ The defaults used in electronic order sets influence medical treatment decisions when the consequences to a patient's health are low. This pattern suggests that physicians cognitively override incorrect default choices but only to a point, and it implies tradeoffs that maximize accuracy and minimize cognitive effort. Results indicate that defaults for low-impact items on electronic templates warrant careful attention because physicians are unlikely to override them.

The evidence supporting the use of vignettes to study physician decision making comes primarily from the study of low-risk decisions and the demonstration of good agreement at the group level between vignettes and actual practice. The validity of using vignettes to predict decision making in more complex, high-risk contexts and at the individual level remains unknown. ⋯ The instrument developed to assess trauma triage decision making performed reliably and detected known group differences. However, it did not predict individual physician performance.

Making surrogate decisions on behalf of incapacitated patients can raise difficult questions for relatives, physicians, and society. Previous research has focused on the accuracy of surrogate decisions (i.e., the proportion of correctly inferred preferences). Less attention has been paid to the procedural satisfaction that patients' surrogates and patients attribute to specific approaches to making surrogate decisions. The objective was to investigate hypothetical patients' and surrogates' procedural satisfaction with specific approaches to making surrogate decisions and whether implementing these preferences would lead to tradeoffs between procedural satisfaction and accuracy. ⋯ Next to decision making by patient-designated surrogates, shared surrogate decision making is the preferred approach among patients and surrogates alike. This approach appears to impose no tradeoff between procedural satisfaction and accuracy. Therefore, shared decision making should be further studied in representative samples of the general population, and if people's preferences prove to be robust, they deserve to be weighted more strongly in legal frameworks in addition to patient-designated surrogates.
