What is a common consequence of improper sterilization procedures?

Improper sterilization procedures can significantly increase the risk of healthcare-associated infections. When surgical instruments and medical devices are not properly sterilized, they may harbor pathogens such as bacteria, viruses, and fungi. This poses a serious threat to patients, as these contaminants can lead to postoperative infections, complications, prolonged hospital stays, and even increased morbidity and mortality. Effective sterilization is crucial in preventing the transmission of infections in healthcare settings, making this consequence a critical factor for patient safety and overall healthcare quality.

In contrast, the other choices reflect outcomes that are not associated with improper sterilization. For example, increased efficiency in surgeries is usually a result of properly sterilized and quickly available instruments. Similarly, a longer instrument lifespan is linked to proper care and sterilization practices rather than improper ones. Reduced training needs for staff would imply that they do not require education on effective sterilization procedures, which is not realistic, as proper training is essential to maintain safety standards in medical environments.
