题目：Analyzing Professional Ethics of Physicians Using Online Patient Reviews:

A Machine Learning Approach

主讲人：Professor David Zhang（张大卫），College of Business, Lehigh University

内容摘要:

Our society permits a few professions, e.g., medicine, law, and accounting, to self-regulate, mainly by setting standards of ethical and professional conduct and disciplining practitioners who fail to meet them. However, there exist few early indicators of medical professionals, specifically doctors’ unethical behavior, which would be valuable to patients as well as to regulators for effective governance. Increasingly, patients use rating websites as open platforms to provide information on their experiences. These reviews may possess operational values on the management and regulation of professional conduct. Yet few studies have theoretically or empirically established the link between patient reviews of professional services and potential or ongoing ethical breaches in medicine. This research introduces a novel set of text-based measures of physicians’ professional ethics using a large dataset of online patient reviews. Drawing upon the literature on healthcare quality and ethics, we design and validate a novel deep-learning-based approach to quantify ethical-related concerns in patient reviews. We combine a large language model with few-shot learning to accurately extract indicators of professional ethics. Empirical results suggest that our novel measures can help predict drug-related deaths, disciplinary actions, details in malpractice claims, and rent-seeking behavior indicated by the association of pharmaceutical firms’ payments to physicians and their prescription behaviors. Our study provides a new framework for detecting early indications of unethical behavior, allowing healthcare organizations and regulators to promote ethical conduct and prevent medical misconduct.
