Abstract
<i>Background:</i> Healthcare professionals face a constant risk of acquiring infections from patients. Exposure to blood, saliva, and sharp instruments increases their susceptibility to various infectious diseases. Proper sterilization and disinfection procedures are crucial for protecting both healthcare workers and patients. <i>Objective:</i> This study aimed to assess the knowledge, attitude, and practices regarding sterilization and disinfection among healthcare professionals in Bangladesh.<i> Methods</i>: A cross-sectional study was conducted at the National Institute of Cardiovascular Diseases & Hospital in Dhaka, Bangladesh, from January to June 2023. A total of 81 healthcare professionals were randomly selected and participated in the study after providing verbal consent. Data collection involved a pre-structured questionnaire focusing on knowledge, attitude, and practices related to sterilization and disinfection. Statistical analysis was performed using SPSS software, and results were presented as frequencies and percentages. Ethical clearance was obtained before the study commenced. <i>Results: </i>The study included healthcare professionals from various backgrounds, with the majority being young adults (21-25 years old). Knowledge assessment revealed a good understanding of sterilization methods, disinfection procedures, post-sterilization instrument management, and waste disposal practices. Additionally, most participants were aware of the hospital's sterilization protocols and infection prevention policies. Regarding attitudes, a positive response was observed towards regular training for staff, proper use of personal protective equipment (PPE), and adherence to sterilization and disinfection guidelines. However, a minority expressed concerns about reusing disposable items. Practices reflected the positive knowledge and attitudes, with a high percentage of participants following hand hygiene protocols, using PPE, and opting for disposable equipment. However, a small number reported experiencing needle-stick injuries, highlighting a potential gap between knowledge and practice. <i>Conclusions:</i> the study found that a majority of healthcare professionals in this setting demonstrated good knowledge, positive attitudes, and appropriate practices regarding sterilization and disinfection. However, a small knowledge, attitude, and practice gap was identified, particularly concerning needle-stick injuries. These findings suggest a need for ongoing education and reinforcement of safe practices to ensure optimal infection prevention and control in healthcare facilities.
