Concern about the epidemic of the acquired immune deficiency syndrome led to discussions in one health district about the dangers of cross-infection from instruments in general practice and health authority clinics. In order to establish what current disinfection practices were in use a telephone survey was adopted as a quick and easy method of data collection. Information was collected on who was responsible for disinfection as well as details of how each instrument was disinfected. Results from 69 general practices and 21 health authority clinice in one health district are reported.
Some form of sterilizer was used in 63 general practices. These included water boilers (49%), dry heat sterilizers (41%), autoclaves (5%) and pressure cookers (5%). Sixty one practices were using metal vaginal specula and of these 29 were disinfecting by boiling, three were using pressure cookers, 18 dry heat, seven chemical methods, three autoclaves and one the central sterile department of the local hospital. Of those who were boiling after simple washing, three practices boiled for five to 10 minutes and reused instruments during the same clinic. Of the 29 using simple boiling 20 (69%) were boiling for less than 20 minutes.
The study highlights the fact that no formal advice has been given on disinfection practice by the DHSS, the health authorities or the family practitioner committees. The need to set up local guidelines and develop practical steps for their introduction are discussed.
