Doctors have physician assistants and registered nurses along with EHR medical databases the hospitals subscribe to for aiding in their patient diagnosis and medical workup via always up-to-date medical coding insurance industry practices (for billing patient health insurance $$$). Any exotic infections/diseases or surgery are farmed out to specialist doctors who are also following medical billing guidelines and a narrow workup to diagnose patients within their specialty. Lawyers have paralegals that dig through the case studies and case law for them along with law databases like LexisNexis.
