“…Moreover, both studies showed that surface disinfection is not being done properly. Furthermore, it has been reported that the bacterial contamination is very high when the surfaces of the tools and equipment in the dental clinic are not disinfected, and that pathogenic sources of infection can spread when a surface disinfectant is not used or when surface disinfection is not properly done [17]. Therefore, all the equipment and tools used during dental procedures, including the dental unit chair, require sterilization or disinfection, and thorough management is necessary [18].…”

This study was conducted to determine the importance of infection prevention and to promote effective disinfection through a comparison of the degrees of bacterial contamination before and after disinfection in the clinical laboratory of a dental hygiene department. The subjects were five infectionprone parts of a dental unit chair, including the back of the chair, the spitting bowl, the bracket button, the light handle, and the bracket handle, of the clinical laboratory of the dental hygiene department of K University in Gangwon Province. To compare the degree of bacterial contamination before disinfection with that after disinfection, a sterilized cotton swab was used to swipe a 1x1cm area on the surface of a dental unit chair before disinfection, after which the cotton swab was promptly put into a sterilized saline solution. Safe Clean Spray (Associated Dental Products Ltd. Kemdent Works, Swindon, UK) was then applied to the same 1 × 1 cm surface of the dental unit chair, and after 1 min, another sterilized cotton swab was used to swipe the area, after which the cotton swab was promptly put into a sterilized saline solution. The bacteria on the cotton swab were smeared onto a Lysogeny broth (LB) agar medium and were cultured for 48 h at 37°C. The colony-forming unit (CFU) results showed less bacteria after surface disinfection, and all the five areas of the dental unit chair showed significant results (p<0.05). The bacterial identification results showed the highest rate of enterococcus in the pre-disinfected spitting bowl, followed by the bracket handle, and the distribution of the gram-positive bacteria was high. Although most of the bacteria were eliminated after surface disinfection, there were some remaining bacteria. Therefore, the frequency of surface disinfection in clinical laboratories is increased to prevent human cross-contamination from bacteria, using a more potent and biostable disinfectant.

“…의료기관의 CSR은 수술실(Operation Room, OR)을 제외 한 병원 내 모든 부서에서 사용한 기구나 물품의 세척, 소독 및 멸균을 담당하고 있다 [9,11]. 이와는 다른 경향으로 수술실과 치과 진료실 등 충분한 세척 공간과 교육받은 숙달된 세척 직원 을 확보하기 어려운 현실을 감안하여 의료기구 재처리 과정은 의료기관의 중앙부서에서 이루어지도록 시스템을 정비할 필 요가 있다 [14]. 최근에는 수술기구도 CSR에서 처리하는 방식 으로 하고 있다 [13].…”

Purpose: This study aimed to identify the knowledge and educational needs of operating room(OR) and central supply room (CSR) nurses about medical equipment reprocessing .Methods: The subjects were 148 operating room and central supply room nurses working at 13 general hospitals in Gyeonggi Province, South Korea. The descriptive study surveyed knowledge and educational needs about medical device reprocessing among nurses. Data were collected from April 1 to May 20, 2022 and, analyzed using the mean and standard deviation, independent t-test, and one-way analysis of variance with SPSS 27.0.Results: The participants were 66 CSR nurses and 82 OR nurses. The score for knowledge was 26.93±4.14 and the highest score in knowledge and educational needs was found for sterilization indicators. The number of beds was significantly associated with knowledge (F=3.16, p=.046), and OR nurses had higher scores for educational needs than CSR nurses (t=3.28, p<.001). Exposure to external education was associated with a higher score for educational needs (t=1.73, p=043). In knowledge, significant differences according to the current department were found for return and cleaning (t=-4.02, p<.001) and, sterilization methods (t=2.57, p=.006). Regarding educational needs, significant differences were found according to the current department in return and cleaning (t=2.83, p=.003), packing (t=2.85, p=.003), sterilization methods (t=3.29, p<.001). Sterilization indicators (t=2.26, p=.013), and sterilization maintenance and release (t=3.85, p<.001).Conclusion: The risk of medical device related infection should be minimized through correct reprocessing. It is necessary to develop an educational program for nurses in charge of reprocessing.

Purpose: Cleaning is crucial for reprocessing reusable surgical instruments (RSIs). In this study, we used the adenosine triphosphate (ATP) bioluminescence method to assess the cleanliness of RSIs according to the cleaning method used.Methods: From April 3 to June 2, 2023, surgical sets, including hemostatic forceps, needle holders, operating scissors, dressing forceps, and suction tubes, that arrived at the decontamination room in the central sterile supply department of one general hospital were selected through convenience sampling. For each of the three cleaning processes, 30 cleaned RSIs were sampled with test swabs for inspection, and the relative light unit value was measured using ATP test equipment.Results: Suction tubes, hemostatic forceps, and needle holders ranked low in cleanliness (x2=11.69, p=.020), and the contamination rate after mechanical cleaning was significantly lower than that after manual cleaning (x2=31.34, p<.001).Conclusion: Surgical instruments treated by manual processing and those containing tubes were associated with the low cleanliness. Therefore, it is necessary to check whether surgical instruments, including tubes, are manually washed at an appropriate level, and regular monitoring will be required.
