Electronic healthcare databases for active drug safety surveillance: is there enough leverage?
Active surveillance using healthcare data-based networks for signal detection is feasible, although the leverage to do so may be low for infrequently used drugs and for rare outcomes. Extending database network size to include data from heterogeneous populations and increasing follow-up time are warranted to maximize leverage of these surveillance systems.
Primary syphilis in Greece is on the rise. Τhe majority of our patients are Greek, despite immigrant influx. Men clearly outnumber women, representing more than 80% of the total number of patients. Furthermore, there seems to be a trend towards predominance of men having sex with men as the core group among male patients.
