FRUGAL INNOVATION AS A HOSPITAL SAFETY STRATEGY:

CASE REPORT ON THE IMPLEMENTATION OF LOW-COST LOCKING MECHANISMS IN MULTIPARAMETER MONITORS

Abstract

The relationship between medical equipment and patient safety is a key determinant of healthcare quality. These high-value devices are exposed to risks such as improper use and misplacement, particularly during episodes of psychomotor agitation in emergency services, which may lead to adverse events. This case report, conducted at Hospital Alberto Urquiza Wanderley (Unimed João Pessoa), describes the development of a low-cost solution designed and implemented by the institution’s Clinical Engineering Department following incidents involving patients and multiparameter monitors. The acquisition of original mounting supports proved financially unfeasible, prompting the creation of anchoring locks produced via 3D printing. The device demonstrated a significantly lower unit cost while maintaining safety and functionality. Practical tests confirmed its effectiveness in preventing equipment damage, unauthorized removal, and loss, as well as avoiding improper transfers between departments. Since its implementation in 2023, no new incidents have been reported. This study reinforces the importance of frugal innovation and highlights the strategic role of Clinical Engineering in risk mitigation, asset protection, patient safety promotion, and the advancement of innovation and health technology management.
