Use of conditional medical orders to minimize moral, ethical, and legal risk in critical care.

Risk managers and ethicists monitor adherence to codes of conduct in the delivery of medical services and proactively participate with providers to create protocols that minimize the moral, ethical, and legal risks inherent in many commonly used medical protocols. "Code/no code" medical orders work well for patients at the extremes who always or never want to undergo a procedure, but they create troubling uncertainties for others by preventing them from expressly requesting procedures under some circumstances but not others. Obeying binary orders such as DNAR (Do Not Attempt Resuscitation) can allow deaths that a patient might want to delay or can expose patients to prolonged suffering they wish to avoid. These risks can be reduced by: (1) fully explaining the nature of proposed interventions and their possible beneficial and adverse effects in varying circumstances; and (2) replacing the traditional dichotomy with a continuum of options from always, through conditionally sometime, to never orders adapted to a range of situations and preferences. The Conditional Medical Orders (CMO) form summarizes patients' preferences regarding resuscitation, ventilation, and artificial hydration and nutrition (ANH) is an efficient way to increases the chance that patients will undergo only the treatments they want.

Evaluation of anesthesia residents using mannequin-based simulation: a multiinstitutional study.

BACKGROUND: Anesthesia simulators can generate reproducible, standardized clinical scenarios for instruction and evaluation purposes. Valid and reliable simulated scenarios and grading systems must be developed to use simulation for evaluation of anesthesia residents. METHODS: After obtaining Human Subjects approval at each of the 10 participating institutions, 99 anesthesia residents consented to be videotaped during their management of four simulated scenarios on MedSim or METI mannequin-based anesthesia simulators. Using two different grading forms, two evaluators at each department independently reviewed the videotapes of the subjects from their institution to score the residents' performance. A third evaluator, at an outside institution, reviewed the videotape again. Statistical analysis was performed for construct- and criterion-related validity, internal consistency, interrater reliability, and intersimulator reliability. A single evaluator reviewed all videotapes a fourth time to determine the frequency of certain management errors. RESULTS: Even advanced anesthesia residents nearing completion of their training made numerous management errors; however, construct-related validity of mannequin-based simulator assessment was supported by an overall improvement in simulator scores from CB and CA-1 to CA-2 and CA-3 levels of training. Subjects rated the simulator scenarios as realistic (3.47 out of possible 4), further supporting construct-related validity. Criterion-related validity was supported by moderate correlation of simulator scores with departmental faculty evaluations (0.37-0.41, P < 0.01), ABA written in-training scores (0.44-0.49, < 0.01), and departmental mock oral board scores (0.44-0.47, P < 0.01). Reliability of the simulator assessment was demonstrated by very good internal consistency (alpha = 0.71-0.76) and excellent interrater reliability (correlation = 0.94-0.96; P < 0.01; kappa = 0.81-0.90). There was no significant difference in METI versus MedSim scores for residents in the same year of training. CONCLUSIONS: Numerous management errors were identified in this study of anesthesia residents from 10 institutions. Further attention to these problems may benefit residency training since advanced residents continued to make these errors. Evaluation of anesthesia residents using mannequin-based simulators shows promise, adding a new dimension to current assessment methods. Further improvements are necessary in the simulation scenarios and grading criteria before mannequin-based simulation is used for accreditation purposes.
