1. Scales of medical institutions and the rates of EO sterilization activities Table 1
The rate of EO sterilization activities of clinics employing less than 10 workers and the rate of clinics that had less than 20 beds were both about 10%. When classified by number of employees, the rate of sterilization activity in medical institutions which had more than or equal to 10 and less than 300 employees was in the order of 40%. But, when classified with the number of beds, the rate was 69% if they had more than or equal to 20 and less than 100 beds. We found that the smaller the number of beds within a set range the higher the rate of EO sterilization activities. There was a 30% difference between institutions with 20 to 99 beds and those with 100 to 500 beds.
2. Rates of EO sterilization in different clinical departments Table 2
Among clinical departments, ophthalmology departments (57.1%) and obstetrics and gynecology departments (42.9%) showed higher rates.
3. Occupational health management system Table 3-1, Table 3-2, Table 3-3
The rates of occupational health professions (OHP) appointment were 58% in institutions with more than or equal to 50 and less than 100 employees, and 80% in institutions with more than or equal to 100 and less than 300 employees.
4. Scales of medical institutions and sterilization activities Table 4
The percentages of employees engaged in sterilization were 1.6% in hospitals and 20.5% in clinics, showing that the clinics have much higher rate.
5. Review of actual conditions
1) Management of sterilization activities
Five items of the questionnaire are relevant to the management of sterilization activities. The 72% (28/39) of medical institutions limited "2: Entrance of workers to the sterilization areas", 51%(20/39) of them recommended wearing "7: Gloves", 5%(2/39) actually applied "8: Full facepiece", 31%(12/39) recommended wearing "9:
Protective clothing for sterilization activities", 90%(35/39) actually "11: Removed the sterilized items quickly".2) Daily management
Four items are relevant to this. The 33%(13/39) of them performed "10: Recording of daily work contents", 69%(27/39) carried out "17: Periodical maintenance", 18%(7/39) did "18: Measurement of EO in the working environment", and 15%(6/39) actually had attachment of "19: Material safety data sheet".
3) Occupational health education Table 5-4
The 90%(35/39) of medical institutions informed workers of the hazards related to EO ("20: Hazards notification to workers"), while 67%(26/39) provided hygiene education for those engaged in sterilization activities ("21: Hygienic education to workers engaging in sterilization activities").
6 Facilities
1) Management of gas circuit from the cylinder to sterilant Table 5-1
As far as the relevant 3 items, 49%(19/39) of medical institutions did "1: EO gas cylinder isolation", 59%(23/39) of them reported the "3: Leak from an airline from a cylinder", 49%(19/39) have set up "4:Local exhaust system in gas supply equipment".
2) Management of sterilant Table 5-2
The 72%(28/39) of medical institutions put limitations on "2: Entrance of workers to the sterilization areas" and 95%(37/39) of them used "5: Fully closed type sterilization equipment". Also 5%(2/39) experienced the "6: Leak from packing and bulb".
3) Exhaust gas process circuit Table 5-3
The 79%(31/39) of medical institutions set up "12: Exclusive exhaust system", 41%(16/39) of them reported that they experienced "15: Back-streaming of the exhaust air from outside".
4) Local ventilation and whole ventilation around the sterilantAs far as local ventilation, less than half (36%(14/39)) of medical institutions have set up "13: Local exhaust ventilation at the opening of the sterilant". Almost of all institutions (97%(38/39)) were provided for "14: Ventilation for the whole working area".
7. The relationship between occupational health management system and items of work environment Table 6
The relationship between occupational health management like assignment of occupational health professionals and the items on Table 6 was tested through Fisher´s exact probability test. In this test a work environment with dedicated OHP was compared with one that didn´t have OHP. In 3 items ("1: Gas cylinder isolation" (p=0.008), "7: Gloves" (p=0.008), "9: Protective clothing for sterilization activities" (p=0.037)), significant differences were observed.
