Benchmarking Companion Diagnostics
What does analysis of the last five years of literature on companion diagnostics tell us about the priorities of the field, and the contributors to it?
New medical interventions often get a lot of media attention – but less is given to companion diagnostics, diagnostic tests and devices that provide essential information for the use of a corresponding intervention. But companion diagnostics are vital to the safety and efficacy of those interventions; they help physicians decide which patients should receive a particular therapy, which patients need to be monitored more closely, and which patients are responding appropriately to treatment.
But what do those “on the ground,” developing and using companion diagnostics, think? What are your peers reading and researching? To find out, we decided to benchmark all of the PubMed-listed literature on the topic. We asked:
- What are the major topics the field?
- Which journals have the greatest impact?
- How is the knowledge available online?
- What types of articles are being published?
- Who are the most prolific authors?
