Impact of individualized nursing interventions on ventilator weaning and respiratory outcomes in ICU patients with severe pneumonia A retrospective cohort study

Abstract

Severe pneumonia frequently necessitates intensive care, with mechanical ventilation serving as a cornerstone of treatment. Despite its life-saving benefits, ventilator weaning poses considerable challenges and is often associated with complications. This study evaluates the efficacy of a tailored nursing approach in enhancing weaning outcomes and accelerating pulmonary recovery. A retrospective analysis was conducted on 110 intensive care units (ICU) patients with severe pneumonia requiring mechanical ventilation at our institution between January 2022 and July 2024. Participants were stratified into 2 cohorts: an intervention group (n = 55) receiving individualized nursing care – encompassing rigorous disease surveillance, optimized airway management, and structured respiratory rehabilitation – and a control group (n = 55) managed with standard protocols. Key findings demonstrated superior clinical metrics in the intervention group, including faster resolution of fever (P < .05), reduced intensive care units (ICU) and hospital stays (P < .05), and shorter mechanical ventilation duration (P < .05). Notably, the intervention group achieved a 96.36% weaning success rate, significantly outperforming the control group’s 81.82% (P = .014). Adverse events were markedly lower in the intervention cohort (10.91% vs 40.00%, P = .003), alongside significantly higher patient satisfaction scores (P = .026). These results underscore that personalized nursing strategies substantially improve ventilator weaning success, expedite respiratory function restoration, mitigate complications, and elevate care satisfaction. The model presents valuable implications for critical care practice.
