Impact of a Multimodal Intervention to Improve Patient Identification in Health Care: A Quasi-Experimental Study

Patient identification is a key aspect to avoid risks and maintain patient safety.

The purpose of this study was to evaluate the impact of a multimodal intervention on patient identification.

A quasi-experimental pre-post study design was used. A multimodal intervention was implemented targeting nursing staff at 2 public Specialized Primary Care Centers. Data on the knowledge levels of nurses and nursing assistants, as well as the implementation of active patient identification, were collected.

The study included 27 health care professionals and 353 direct observations of patient active identification. Knowledge was assessed via a questionnaire, and active identification observations were conducted between March 2022 and December 2023. After the intervention, the correct performance rate improved to 100%, slightly decreasing to 82.3% over 21 months post-intervention. All evaluated knowledge items showed significant improvement post-intervention.

The multimodal intervention significantly improved active identification knowledge and practice, enhancing patient safety.
