“…About 79% of the healthcare workers in primary and secondary care hospitals in Nepal thought that wrapped sterilized medical devices could be stored for seven days at room temperature before use. A shelf-life of 7 days is very much less than the shelf-life indicated by many previous studies, and there is be growing support for the event-based determination of shelf-life rather than the time-based shelf-life of sterilized medical devices [ 46 – 49 ]. When event-based shelf-life is implemented, wrapped medical devices are stored for a longer time, i.e.…”

Background Healthcare facilities reprocess and sterilize reusable medical devices before each invasive clinical procedure, such as surgery, to prevent person-to-person or environmental transmission of pathogens through medical devices. We conducted a nationwide multi-centre cross-sectional survey in primary and secondary-care public hospitals in Nepal to assess the knowledge and attitudes of healthcare workers towards sterilization and reuse of medical devices. Methods We carried out a multi-centre cross-sectional survey comprising eleven primary-care (two district-level and nine district hospitals) and two secondary-care (zonal hospitals) public hospitals which covered all seven provinces of Nepal. Survey questionnaires were distributed to 234 healthcare workers including doctors, nurses, paramedics, and office assistants (involved in medical device reprocessing); 219 (93.6%) returned the completed questionnaire. Descriptive analyses of demographic information, knowledge and attitude responses of survey participants were performed. Logistic regression and ordinal regression models for complex samples were used to investigate associations between responses and independent variables. Results Except for a few areas, more than 70% of healthcare workers had proper knowledge about different aspects of sterilization and reuse of medical devices. Paramedics and office assistants were less likely to have the correct knowledge in different aspects compared to nurses. Permanent staff were more likely to give correct answers to some knowledge questions compared to temporary staff. Previous infection control training was positively associated with correct responses to some knowledge items. Most of the healthcare workers had positive attitudes towards different aspects of sterilization and reuse of medical devices, and nurses were more likely to have positive attitudes compared with other staff categories. Conclusions Most of the healthcare workers had correct knowledge and positive attitudes towards most areas of sterilization and reuse of medical devices. However, they need proper education and training in some areas such as sterilization procedures, storage of sterilized devices, prion decontamination and standard precautions.

“…One study verified that, after two years, 100% (152) of the sterilized and stored packages, which suffered no adverse events, were sterile ( 22 ) . Another study concluded that even after exposure to the microorganism Serratia marcescens , an item with a safe microbial barrier remained sterile after 180 days ( 23 ) . Event-related sterility is safe and should, therefore, replace time-related expiration ( 22 ) .…”

OBJECTIVES: to adapt and validate, by expert consensus, a set of indicators used to assess the sterilization process of dental, medical and hospital supplies to be used in PHC services. METHOD: qualitative methodological study performed in two stages. The first stage included a focal group composed of experts to adapt the indicators to be used in PHC. In the second stage, the indicators were validated using a 4-point Likert scale, which was completed by judges. A Content Validity Index of ≥ 0.75 was considered to show approval of the indicators. RESULTS: the adaptations implemented by the focal group mainly referred to the physical structure, inclusion of dental care professionals, inclusion of chemical disinfection, and replacement of the hot air and moist heat sterilization methods. The validation stage resulted in an index of 0.96, which ranged from 0.90 to 1.00, for the components of the indicators. CONCLUSION: the judges considered the indicators after adaptation to be validated. Even though there may be differences among items processed around the world, there certainly are common characteristics, especially in countries with economic and cultural environments similar to Brazil. The inclusion of these indicators to assess the safety of healthcare supplies used in PHC services should be considered.

“…Therefore, potentially infectious aerosolized particles may land on sterile packages that are not contained or covered in the OR. There also is evidence that instruments wrapped or packaged and sterilized according to the manufacturer’s instructions for use remain sterile until something occurs that affects sterility (eg, tear, puncture, exposure to out‐of‐range humidity), which is known as event‐related sterility 1,8‐12 …”
