# Evaluation of the effectiveness of a multimodal aspiration prevention system in stroke rehabilitation nursing

## TL;DR

A new system called MAPS was tested to prevent aspiration and pneumonia in stroke patients during rehabilitation, showing promising results.

## Contribution

The study introduces and evaluates a novel multimodal system for aspiration prevention in stroke rehabilitation.

## Key findings

- MAPS significantly reduced overt aspiration incidence compared to conventional care.
- Stroke-associated pneumonia rates decreased substantially with MAPS implementation.
- Patient satisfaction scores reached 99.2% in the MAPS group.

## Abstract

To evaluate the efficacy of the Multimodal Aspiration Prevention System (MAPS) in reducing aspiration incidence, preventing pneumonia, and improving swallowing function in stroke rehabilitation patients.

A before-after controlled study was conducted involving 855 stroke rehabilitation patients (408 in the MAPS intervention group, 447 in the historical control group). The intervention group received MAPS, including a three-tier risk warning system, standardized intervention procedures, and multidisciplinary collaboration, while the control group received conventional care. Primary outcomes included overt aspiration incidence, with secondary outcomes assessing stroke-associated pneumonia rates, swallowing function improvement, psychological status, and patient satisfaction.

The MAPS group demonstrated a significantly lower incidence of overt aspiration compared to control group (p < 0.05), with complete elimination of aspiration events achieved by the second month of implementation. Secondary outcomes revealed clinically meaningful improvements following MAPS adoption: stroke-associated pneumonia rates decreased substantially (p < 0.05), psychological assessments indicated significant alleviation of anxiety and depression symptoms (p < 0.05), and patient satisfaction scores reached 99.2%. Although swallowing function showed numerical improvement in the MAPS group, the difference did not reach statistical significance when compared to the control group (p > 0.05).

MAPS effectively reduces aspiration and pneumonia risks while enhancing psychological well-being and patient satisfaction in stroke rehabilitation. Its closed-loop management model demonstrates clinical applicability. Further multicenter studies are warranted to validate long-term benefits.
