I think the main difference, at least in my case, between a journalist and a blogger might be the lack of a traditional mast head, no assigned stories (I don't accept them), and a singular interest in teasing out the healthcare complexities, potential solutions, and industry adjacent insights we ignore at our own peril.
You might be surprised how the pendulum is swinging. The majority of conferences I attend (98%) I do not pay for access. I register as press, they take a look at my platform--they invite me as media. I belong to the AHCJ, NASW, and IRE. I intentionally didn't hyperlink. Go flex your journalistic muscles and hunt down the organizations.
The Investigative Reporters & Editors Journal is a treasure trove. If you are approved for membership you also get a 3 year Tableau Desktop license. They are serious about serving their members.
So where is all this data?
I use a wide variety of government databases, non-proprietary and non-proprietary databases in medicine, and a handful of other sources for data. But maybe you should consider creating your own database--an up to date resource ready to go when you need relevant data to inform your content.
Social determinants of health are a critical backdrop to narratives on healthcare, disease status, and economics. I rely quite heavily on the American Community Survey and a wide variety of specific variables. If you are interested in quicker access and can afford a small fee, Public Insight provides access to connected datasets and includes tutorials.
MedDRA can be used to analyse individual medical events (e.g., “Influenza”) or issues involving a system, organ or etiology (e.g., infections) using its hierarchical structure. MedDRA can be used for signal detection and monitoring of clinical syndromes whose symptoms encompass numerous systems or organs using its multiaxial hierarchy or through the special feature of Standardised MedDRA Queries.
