UKTIS - information

What written information is available?
To assist with enquiry answering, summary information has been developed for a number of drugs and chemicals to assist in the provision of risk assessments following exposure during pregnancy. The UKTIS now has 410 summaries available and of these, 350 are available directly to health professionals on TOXBASE. Since November 2011, monograph summaries were made freely available on the UKTIS website.


How is follow up done?
Prospective data collection using standardised procedures occurs by contacting an appropriate health professional, usually the patient’s general practitioner. This happens on two occasions:

  • Around the time of the enquiry;
  • Approximately four weeks after the expected date of delivery (EDD).

What information is collected and held?

Information collected by the UKTIS includes:

  • Details about the original enquirer, including their name, contact details; and the referring Unit and department;
  • Details about the mother, including her name and date of birth or age, past medical history and any medications taken therapeutically, obstetric history (how many previous pregnancies, any history of miscarriage or malformations), and her expected date of delivery;
  • Details about the suspected exposure, including the agent(s) involved, route of exposure, estimated dose, date, time and duration of exposure, indication for treatment (if appropriate), use of protective equipment (if appropriate, e.g. for occupational exposures), and maternal symptoms, investigation results and treatment so far.
