Limited Public Profiles Unlike private practice specialists, many EM group leaders don’t maintain robust online profiles, making LinkedIn or general searches unreliable. 4. Time-Sensitive Workflows Emergency medicine is fast-paced. Gaining the attention of key stakeholders who are constantly dealing with urgent cases can be particularly tough.
