Objectives: This study aimed to evaluate the relationship between oral health professionals' knowledge, attitude, and practice with regard to infectious waste management and to identify related factors influencing it. Methods: The study comprised of 219 oral health professionals from select dental clinics and public health centers recruited between August 25, 2016 and September 5, 2016, who agreed to participate in the study with full understanding of the study objectives. A self-reported questionnaire was administered, which consisted of 22 items on knowledge of infectious waste management, 9 items on attitude, and 16 items on practice. Data were analyzed using Pearson's correlation coefficient and stepwise multiple regression analyses. Results: The age, knowledge, and clinical attitude of oral health professionals significantly correlated with waste management practice. Specifically, infectious waste management practice improved with increasing age, a greater level of knowledge, and a more positive clinical attitude. Additionally, the standardized regression coefficient demonstrated that, of these three factors, clinical attitude more strongly correlated with effective waste management practice, followed by age and level of knowledge. Conclusions: These results indicated that oral health professionals had a low level of knowledge regarding infectious waste management, and a more positive clinical attitude resulted in better practices. Therefore, the development of detailed and active education guidelines and strategies are needed to enhance the attitude, knowledge, and practice of oral health professionals with regard to infectious waste management.

Since improper management practices of solid medical waste (SMW) could potentially result in serious health risks and environmental problems, it is very important to properly treat and dispose of the medical wastes. In this study, current practices of SMW management from storage to final disposal stage in 12 health care facilities (HCFs) of Burundi were investigated using the official government reports. The results showed that 75% and 92% of HCFs used uncovered wheelbarrows and trucks for on-site or off-site SMW transportation, respectively, indicating that most transportation equipment and waste workers are not safely protected. The results also showed that 92.8% of SMW (15,736.4 ton) from all 12 HCFs were inappropriately disposed of through uncontrolled land disposal and incineration. If pharmaceutical wastes and discarded medical plastics (29.5% of SMW) can be separated and treated properly, the treatment costs can be reduced and resource savings can be achieved. Raising awareness of healthcare workers and general public about potential health effects arising from improper SMW management, sufficient financial and human resources for the treatment facilities (especially incinerators), and effective regulations and guidelines for transportation and treatment of SWM are some of the major tasks for safe and sustainable medical waste management in Burundi.

Objectives: Because the amount of medical waste (i.e., health-care waste) generated in Korea is rapidly increasing and social concern against its safety is widespread, a number of issues related with medical wastes are being discussed. The purpose of this study is to compare diverse medical waste management systems worldwide and propose future directions of a medical waste management system in Korea. Methods: Literature review was conducted mainly on the WHO, and developed countries such as the European Union (Germany, Belgium and UK), Japan and the United States. For these countries, the data with respect to their systems for medical waste management ranging from the definition of medical waste to the whole processes of collection, transportation and disposal were summarized and compared. Results: The terminology and classification of medical wastes were not consistent for WHO recommendation, EU, Japan, US and Korea. Comparison of the collection, storage, transportation and disposal of medical waste showed that Korea had rather stronger regulations for medical waste management compared to developed countries including Belgium (Flanders region), Germany, Japan and the US. Considering that developed countries adopt rather flexible disposal system especially for general medical wastes which pose lower possibility of infection, Korean government could consider diversifying disposal methods other than incineration. It may also be very important to try to reduce the amount of medical wastes and enough capacity for off-site incineration are secured. Conclusion: Our study of international comparisons suggests that it is necessary to continue to identify advantages and disadvantages of the current medical waste management systems and establish more effective one in Korea.

의료폐기물은 감염성물질을 함유하고 있는 모든 종류의 폐기물을 가리키며 전염을 예방하기 위해 운송에 신중을 기해야 한다. 처리 수단으로의 소각은 부피 감소, 악취 제거, 위해성 측면에서 매립이나 투기보다 장점을 갖고 있다. 야외 소각이나 바람직하지 않은 환경에서의 소각은 환경오염 물질의 대기 중 배출을, 생물학적 폐기물의 매립은 토양과 수질오염을 야기시킨다. 피지의 대부분의 2차 병원은 의료 폐기물을 세 군데에 있는 3차 병원으로 차량 또는 배로 이송하여 소각 처리한다. 어떤 의료폐기물은 일반폐기물로 간주되어 현장에서 야외 소각되거나 출산 시 발생한 생물학적 의료폐기물은 매립되기도 하였다. 이런 측면에서 의료폐기물 처리 관련 인력들에 대한 인식 증진을 위한 교육이 시급하다. 피지에서의 의료폐기물 처리는 단일 도로를 따르는 차량운송, 배를 이용한 도서간 운송보다 소형 소각로를 이용한 현장소각이 권장되며, 가이드라인 제정, 관련 인력 훈련, 정부의 법률적 제정 등 의료 폐기물 처리를 위한 기반 조성이 필요하다.

In order to protect Rescue 119 workers exposed on the spot from potential infection, this study identified their awareness and practices of infection control so that it could help preventing them from infection and also provide basic materials necessary for pre-hospital infection control. This study applied questionnaire survey to total 215 Rescue 119 workers at fire stations in Jeonbuk province, Jeonnam province and Gwangju city from July 14 to Sept. 14, 2006 for the benefit of data collection. The questionnaire about possible associations between awareness and practices of infection control consisted of total 46 times across 6 categories such as washing hands during emergency activities ; fluid therapy and injection ; respirator maintenance; individual hygienics ; disinfectant supplies and equipments maintenance ; and control of infectious wastes. And collected data were processed using SPSS statistic program to analyze frequency and percentage, mean and standard deviation, Pearson's correlation coefficient, t-test and one-way ANOVA. As a result, this study came to the following conclusions : In terms of awareness about infection control, our respondents showed highest awareness about infectious waste control, and also showed highest level of practices in washing hands during emergency activities. Throughout all domains, awareness means were higher than practice means. In particular, infectious waste control was the domain of significant differences between awareness and practices. In terms of associations between awareness and individual characteristics, it was found that female rescue worker group and hospital/general hospital career group (before joining the Rescue 119) showed significantly higher awareness on statistic level. In regard to associations between individual characteristics and practices, it was found that female rescue worker group showed higher level of practices than male group on statistic level. This study also analyzed correlations between rescue workers' awareness and practice of infection control. As a result, it was found that the higher awareness was in correlations with the higher practices across all 6 domains including washing hands. In addition, the higher awareness of a questionnaire item was in significantly positive correlations with the higher practice of other items. However, our respondents showed high awareness about anti-infection, but low practices in reality. This indicates necessity of devising possible solutions to improve the practices as much as awareness. Especially, it was noted that major reasons for insufficient practices of infection control guideline come from unhabituated practices and lack of supports for infection-preventing supplies and protective device (mask, etc). Hence, it is necessary to provide more infection-preventing supplies for local rescue workers sufficiently, in parallel with steady habituation of infection control. Furthermore, it is required to manage and study infection control policies even at pre-hospital step in efforts for effective infection control, education and activities.
