ABSTRACT
OBJECTIVES: An awareness of the risk of blood-borne infections among dentists has been promoted by the Dutch Dental Association (NMT) as part of their quality and safety programme, and a nationally operating expert counselling centre was contracted to manage all reported incidents. METHODS: We analysed data on hepatitis B vaccination status, sex and age for all reported incidents recorded by this centre during 2008. We compared this with data collected at same time during a national survey to assess the performance of the centre. The number of blood exposure injuries among dentists and their assistants, and reporting behaviour, were also assessed. RESULTS: In 2008, 387 incidents were reported to the counselling centre. The percentage of high-risk incidents was 16, with a risk of hepatitis B, hepatitis C and HIV infections. In the hepatitis B cases, 12% had no or insufficient immunization. Eight per cent of those injured were unable to start HIV Post-Exposition Prophylaxis because they reported too late. Of the 1442 surveys sent, 487 (34%) were returned. Dentists estimated levels of hepatitis B vaccination at 98%. Thirty-two per cent reported to have had one or more injuries in their practice in 2008. Of these, 37% were counselled by the expert centre, 18% were counselled by others and 45% sought no medical attention. The performance of the counselling centre received a positive score (95%). A need for more information about vaccination and blood-borne infections in dentistry (52%) was reported. CONCLUSIONS: Nationwide data show blood exposure incidents occur frequently in dental settings, with a considerable number of high-risk incidents. Administering anaesthetics and cleaning-up are major risk factors. There is a need to intensify measures for safe working conditions in dental care settings in the Netherlands, irrespective of the type of dental practice.
