Abstract

IntroductionClassifying the ethical issues in clinical ethics consultations is important to clinical practice and scholarship. We conducted a systematic review to characterize the typologies used to analyze clinical ethics consultations.MethodsWe identified empirical studies of clinical ethics consultation that reported types of ethical issues using PubMed. We screened these articles based on their titles and abstracts, and then by a review of their full text. We extracted study characteristics and typologies and coded the typologies.ResultsWe reviewed 428 articles; 30 of the articles fulfilled our inclusion criteria. We identified 27 unique typologies. Each typology contained five to 47 categories (mean = 18). The most common categories were do-not-attempt-resuscitation orders (19 typologies, 70 percent), capacity (18 typologies, 67 percent), withholding (18 typologies, 67 percent), withdrawing (17 typologies, 63 percent), and surrogate or proxy (16 typologies, 59 percent). Only seven (26 percent) of the typologies contained all five of the most common categories. The typologies we used to characterize clinical ethics consultations exhibit significant heterogeneity and several conceptual limitations. A common typology is needed whose development may require multi-institutional collaboration and could be facilitated by professional organizations.
