Abstract

Objective: This paper describes an objective method for assessing the decontamination procedures used for reprocessing dental instruments in primary dental care facilities. Materials and methods: The study population comprised all general dental practitioners in Scotland with an NHS list number. A two-stage process was used to identify which surgeries were to be surveyed, using a proportional stratifi ed random sampling method. First, practices were randomly selected in proportion to the distribution of practices within each of the health boards. Then, if there was more than one dentist within a selected practice, simple random sampling was used to identify a single dentist within the selected practice to be approached. The surgery that the dentist worked from and its associated decontamination facilities were the subject of the survey. A set of data collection forms provided questions designed to investigate compliance with extant guidance documents on decontamination. Specifi c training for the survey team members was provided during a three day course, to ensure consistency of approach. The data collection forms were piloted in 20 dental surgeries. Results: A methodology was developed, which utilised both staff interviews and direct observation of decontamination processes. Data were collected on a set of 28 standard forms, which could be machine read. Three hundred and seventy-three dentists were selected at random from the dental practitioners list held by Practitioner Services, Scotland. One hundred and eighty-nine practitioners either declined to participate or could not be contacted at the address supplied. One hundred and eighty-four surgeries were surveyed, data were available for analysis from 179 sites. Data from fi ve sites were rejected because of illegibility (three) and incomplete data (two). Each surgery survey was undertaken by a team of two surveyors, comprising one infection control/decontamination expert and one experienced dental practitioner. The survey team interviewed the dental practitioner and dental nurse, reviewed documentation relevant to the survey, directly observed decontamination practices and recorded the physical layout of the premises. Conclusion: The use of machine readable data collection forms, trained survey staff and direct observation of decontamination protocols provides a workable method for accurate collection of decontamination practice in primary care facilities. © 2007 Nature Publishing Group.
