[Patient safety in general dental practice 2009]

In recent years various studies have been published which indicate that adverse events in health care facilities are the result of structural factors. In 2009 a national study was carried out in the Netherlands to gain insight into patient safety in primary care settings, including general dental practices. In 20 randomly selected practices, patient records were investigated and oral care professionals reported, during a period of 2 weeks, adverse events which occurred. For each practice, 2 researchers screened, with the help of a checklist, 50 randomly selected patient records covering a period of 1 year. A total of 8 preventable adverse events were found in the 1000 patient records (0.8%). Anonymous reports made during the 2 weeks of the research period resulted in 7 adverse events. Practically all of the adverse events had to do with diagnostics and treatment and resulted in limited harmful consequences for patients. On the basis of these results, oral care in general dental practice would appear to be safe, but the concept 'patient safety' is not at all or only minimally active among general dental practitioners. Regarding patient safety performance, improvement in the quality of record-keeping would be desirable.
