Which innovations are examples of improving patient safety in hospitals?

The choice of barcode medication administration as an innovation for improving patient safety is indeed a strong example. This technology enhances the accuracy of medication administration by utilizing barcodes on both medications and patients' wristbands. When healthcare providers scan these barcodes, it ensures that the right patient receives the right medication at the right dose and time, significantly reducing the potential for medication errors. This process not only streamlines the administration workflow but also integrates with electronic health records, providing real-time documentation and accountability.

In contrast, the other options do not promote patient safety in the same way. Increased staffing can improve patient safety by ensuring that patients receive more attentive care, however, it is not a direct technological innovation aimed at reducing errors. Physical constraints on patients can be controversial as they may sometimes compromise patient dignity and well-being, and they do not inherently improve safety but can actually lead to increased risks of injury if not managed properly. Paper charting systems are outdated and prone to errors, lacking the benefits of digitization, such as easy access to patient data and decision support, which are crucial for ensuring both safety and efficiency in patient care.
