PDCA-Based Precision Nursing for Stroke Patients With Tracheostomy (PDCA-ST)

2026年7月4日 更新者:AnQi Ba、The First Affiliated Hospital of Soochow University

Effect of a PDCA Cycle-Based Precision Nursing Program on Clinical Outcomes in Stroke Patients With Tracheostomy: A Randomized Controlled Trial

Stroke patients undergoing tracheostomy are at high risk of pulmonary complications because tracheostomy bypasses the normal upper airway defense mechanisms and increases the risk of airway colonization and infection. Although routine nursing care is widely used, a standardized quality improvement strategy for airway management remains lacking.

This single-center, prospective, randomized, single-blind controlled trial aims to evaluate whether a PDCA (Plan-Do-Check-Act) cycle-based precision nursing program improves clinical outcomes in stroke patients with tracheostomy compared with routine nursing care. Eighty eligible participants will be randomly assigned in a 1:1 ratio to receive either the PDCA-based precision nursing intervention or routine nursing. The primary outcome is the incidence of pulmonary infection. Secondary outcomes include sputum viscosity, arterial blood gas parameters (PaO₂, PaCO₂, and oxygenation index), nursing satisfaction, and safety outcomes including unplanned extubation, incision infection, and airway mucosal injury.

調査の概要

詳細な説明

Background: Stroke is a leading cause of disability and mortality worldwide. Many patients with severe stroke require tracheostomy to maintain airway patency and facilitate respiratory management. However, tracheostomy bypasses the physiological functions of the upper airway, increasing the risks of pulmonary infection, secretion retention, and airway-related complications. Although routine airway nursing is commonly implemented, evidence supporting a structured quality improvement model for tracheostomy care remains limited.

Objective: The primary objective is to determine whether a PDCA cycle-based precision nursing program reduces the incidence of pulmonary infection compared with routine nursing care in stroke patients with tracheostomy.

Secondary objectives are to evaluate the effects of the intervention on sputum viscosity, arterial blood gas parameters (PaO₂, PaCO₂, and oxygenation index), nursing satisfaction, and the occurrence of adverse events including unplanned extubation, incision infection, and airway mucosal injury.

Study Design: This is a prospective, single-center, randomized, single-blind, parallel-group controlled trial. Eighty participants meeting the eligibility criteria will be randomly allocated in a 1:1 ratio to either the intervention group or the control group using a computer-generated randomization sequence with sealed opaque envelopes. Outcome assessors and statisticians will remain blinded to treatment allocation.

Intervention: Participants in the control group will receive routine nursing care, including standard airway management, oxygen therapy, suctioning, nebulization, nutritional support, and routine tracheostomy care.

Participants in the intervention group will receive routine nursing plus a structured PDCA cycle-based precision nursing program. The intervention consists of multidisciplinary quality management following the Plan-Do-Check-Act framework together with seven standardized nursing modules, including catheter safety management, continuous airway humidification, graded secretion management, standardized incision care, individualized airway clearance, aspiration prevention, and early rehabilitation training.

Outcome Measures: The primary outcome is the incidence of pulmonary infection during hospitalization. Secondary outcomes include sputum viscosity, arterial blood gas parameters (PaO₂, PaCO₂, oxygenation index), nursing satisfaction, and safety outcomes including unplanned extubation, incision infection, and airway mucosal injury.

Study Duration: Participant recruitment is planned from March 2025 through March 2026. Participants will receive the assigned intervention from enrollment until hospital discharge or transfer. No post-discharge follow-up is planned.

実験的:PDCA-Based Precision Nursing Group
Participants in this group will receive routine nursing care plus a PDCA cycle-based precision nursing program from enrollment until hospital discharge or transfer. The intervention includes catheter safety management, continuous airway humidification, graded secretion management, standardized incision care, individualized airway clearance, aspiration prevention, and early rehabilitation training.
The PDCA cycle-based precision nursing program is a structured nursing intervention delivered in addition to routine nursing care. It follows the Plan-Do-Check-Act quality improvement framework and includes catheter safety management, continuous airway humidification, graded secretion management, standardized incision care, individualized airway clearance, aspiration prevention, and early rehabilitation training. The intervention is implemented from enrollment until hospital discharge or transfer.
Routine nursing care includes standard airway management, oxygen therapy, suctioning, nebulization, nutritional support, and routine tracheostomy wound care according to usual clinical practice. It does not include the structured PDCA cycle-based precision nursing program.
アクティブコンパレータ:Routine Nursing Group
