Clinical practice and the perceived importance of identifying high risk patients.

The Royal Free NHS Trust is implementing a Universal Precautions policy for blood and body fluids. Anticipating the introduction of this policy, a questionnaire was sent to a sample of staff and students who work with patients or clinical specimens. The questionnaire covered: views about identifying 'high risk' patients and specimens; perceived risks of human immunodeficiency virus (HIV) and hepatitis B infection from blood exposures; and current practices to avoid exposure to blood. Over half the respondents thought it important to identify high risk patients and specimens. Such respondents were more likely to overestimate the risks of HIV and hepatitis B virus transmission after blood exposures, they were less likely to wear gloves and more likely to resheathe needles. Although two-thirds of respondents thought Universal Precautions would reduce their risk of blood-borne infections, they identified a number of reasons why it would be difficult for them to practice it. Those who thought it important to identify high risk patients gave more reasons than other respondents. This survey indicates that many staff believe it is important to identify high risk patients and this belief seems to influence clinical practice. In order to implement a policy of Universal Precautions successfully, it is necessary to address underlying beliefs as well as giving staff information and training.
