As a freelance healthcare writer, you write content related to the healthcare industry, from marketing materials to patient education to health news blog posts. If you have a science background, you can write projects geared toward healthcare professionals, such as courses for continuing education, regulatory writing, and journal articles. Because you work on an independent basis, your duties and responsibilities also include prospecting new clients, building client relationships, and continuing your education within your niche. Today’s medical writers tend to find a specialization within the healthcare sector to distinguish themselves from other freelance writers. Depending on your specialization, your duties might be more investigative or informative.
