Epidemiological study on knowledge, attitudes and behaviour of health care workers with respect to HIV infection

To analyse knowledge, perception of risk, attitudes and behaviour towards HIV infection among health workers in two hospitals in the North-East of Italy, we sent all health care workers who were working in direct contact with patients an anonymous self-administered questionnaire covering personal and occupational data, perception and knowledge of risk, behaviour in routine activities, attitudes towards and care of HIV patients. The response rate was 70.06%. The perception of the risk of acquiring HIV infection was influenced by occupational qualification, by work unit and by having cared for a HIV-positive patient. Scientific knowledge about transmissibility of HIV infection was poor and 11.3% of the staff did not know the Universal Precautions. 28.3% behaved correctly in recapping needles, but with patients considered not at risk 29.9% did not use any protection in drawing venous blood. A significant portion of staff showed low willingness to care for HIV-positive patients. We found a high mean perception of the risk of contracting HIV infection through occupational exposure; health workers overestimated the specific risk and wrong behavioural attitudes persisted. To conclude, more attention should be paid to educational programs for health workers.
