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

Abstract

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

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

Methods: 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.

Results: 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.

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