Plain Language Summary Biologics are a type of medicine becoming widespread in the treatment of many diverse diseases. Biologics are injected under the skin and can sometimes be injected by patients themselves at home. Many injection devices are available to help patients with this self-injection, and fall into three broad categories: prefilled syringes, prefilled pens, and electromechanical devices. Each has its own advantages and disadvantages, and different devices suit different patients. For example, some patients have difficulty achieving consistent and successful self-injection because of limited hand movement or become anxious at the prospect of self-injection or injection-site pain. These factors can reduce patients’ ability and willingness to take medication as prescribed and may worsen their overall experience. Further, many disposable devices involve single-use plastics and may pose an environmental toll. Reusable electromechanical devices are the newest of the available devices and offer enhanced features over some earlier devices. These include customisable injection speeds or durations, consistent rates of injection, electronic injection logs, reminders, and real-time instructions. Evidence suggests that patients using electromechanical devices may have higher rates of adherence (i.e. more patients take their medication as prescribed) than those using other devices. Additionally, with time and further research, the reusability of electromechanical devices may prove to lighten the environmental impact compared with disposable devices. Here we discuss the differences between prefilled pens, prefilled syringes, and electromechanical devices, and explore the features that may help reduce injection-associated pain and anxiety, improve patient experience, connectivity, and adherence, and drive greater sustainability.
