Minimizing contamination in the use of personal protective equipment: Simulation results through tracking contamination and enhanced protocols.

BACKGROUND: Due to variations and the inadequate use of personal protective equipment (PPE), this study aimed to evaluate our enhanced PPE protocols for minimizing doffing contamination. METHODS: Among 3 PPE kits (simple, Level D, and Level C), 30 participants conducted the first simulation in their adapted way and the second following enhanced protocols. After donning, participants performed a 1-minute simulation of direct care on a patient simulator covered with fluorescent powder. For tracking contamination routes between doffing processes, fluorescent powder contamination was examined with ultraviolet lamps in the darkened room. RESULTS: Participants were mostly registered nurses (N = 27, 90%), female (87%), and on average 31.7 years old with 8.5 years of clinical experience. Among 61 total simulations, 32 had at least 1 contamination (52.5%); "Noticeable" level (40%) at the "hands-fingers" and "shirt" body areas were most frequent. For first and second simulations with identical PPE kits, compared to the first with adapted practice, the second with enhanced protocols showed a significant reduction in doffing contamination rates (72.7% vs 22.7%, P = .0009 for both Level C and D; 77.8% vs 27.8%, P = .0027 for Level D). CONCLUSIONS: Our enhanced protocols could significantly reduce contaminations. More studies are necessary to provide safer PPE protocol options.

South Korea's responses to stop the COVID-19 pandemic.

BACKGROUND: South Korea's aggressive responses to the coronavirus disease 2019 (COVID-19) have greatly slowed the epidemic without regional lockdowns. METHODS: The Korean Centers for Disease Control and Prevention's daily briefings were thoroughly reviewed. Information about hospital countermeasures and government coordination was collected via telephone interviews with 4 infection control team leaders, 1 emergency department nurse, and 1 infectious disease physician in Korea. RESULTS: After the 2015 Middle East Respiratory Syndrome outbreak, the government and hospitals prepared for the inevitable outbreak of emerging infectious diseases by reforming the epidemic preparedness system. As a result, COVID-19 diagnostic test kits were quickly developed, enabling extensive early detection of potential cases. Other key steps were tracking cases, finding exposed individuals, coordinating case assignments with health care facilities, and selective clinic screenings for visitors' entering hospitals with mandatory mask wearing. Consequently, after overcoming the initial peak of the outbreak, which was related to a religious group, Korea has been able to maintain daily new cases at around 100 and to less than 50 daily cases in the second week of April. CONCLUSIONS: To counter the COVID-19 pandemic, which may persist, long-term, sustained response strategies must be prepared along with coordination between government and health systems.

Difficulties in using personal protective equipment: Training experiences with the 2015 outbreak of Middle East respiratory syndrome in Korea.

This study aimed to evaluate practical barriers to personal protective equipment (PPE) use found through health care personnel (HCP) training sessions held during and after the 2015 Middle East respiratory syndrome outbreak in Korea. Difficulties observed were ill-fitting sizes, anxiety, confusion from unstandardized protocols, doubts about PPE quality and effectiveness, and complexity of using several PPE items together. Further research to generate robust evidence and repeated HCP trainings are necessary to ensure HCP and patient safety in future outbreaks.

Qualitative content analysis of psychologic discomfort and coping process after needlestick injuries among health care workers.

BACKGROUND: This study was designed to survey psychologic discomfort and coping processes of health care workers that suffered needlestick injuries (NSIs). METHODS: This qualitative analysis was performed with 15 health care workers who experienced NSIs. Data were collected using face-to-face interviews. The study subjects were asked the following: please describe the psychologic discomfort that you experienced after the NSI incidence. Data were evaluated by qualitative content analysis. RESULTS: Types of psychologic discomfort after NSI among health care workers included anxiety, anger, and feelings of guilt. Some personnel adopted active coping strategies, such as seeking first aid or reporting the incident to a monitoring system, whereas others used passive coping methods, such as avoidance of reporting the incident, vague expectancy to have no problems, and reliance on religious beliefs. Recommended support strategies to improve the prevention of NSIs were augmenting employee education and increasing recognition of techniques for avoiding NSIs. CONCLUSION: Medical institutions need to provide employees with repeated education so that they are familiar with guidelines for preventing NSIs and to stimulate their alertness to the risk of injuries at any time, in any place, and to anybody.
